Coordination Costs, Institutional Investors, and Firm Value Abstract Coordination costs among institutional investors have a signi…cant impact on corporate governance and …rm value. We use two measures, one based on the geographic distance among institutional shareholders and the other based on the correlation in their portfolio allocation decisions, to proxy for coordination costs. We …nd that, after controlling for other factors, coordination costs are negatively associated with …rm value as proxied by industry-adjusted Tobin’s q. This e¤ect is robust to controlling for the endogeneity of the institutional ownership structure. Using the 1992 proxy reform as an exogenous shock that relaxes restrictions on communication and coordination among shareholders, we show that this e¤ect becomes signi…cantly stronger after the reform. We further show that the ease of coordination among institutions is associated with fewer anti-takeover provisions adopted by the …rm, higher equity-based pay for CEOs, and improved CEO turnover-performance sensitivities. Overall, these …ndings suggest that the ease of coordination improves …rm value by enhancing the governance role of institutional investors. JEL Classification: G23, G32, G34 Keywords: Coordination costs; Institutional investors; Corporate governance; Firm value 1 Introduction While institutional investors collectively hold the majority of the U.S. equity market, their in‡uence on corporate governance and corporate performance remains unclear. Theoretical work suggests that institutional investors, as large shareholders, can discipline corporate managers through active monitoring and intervention (Shleifer and Vishny, 1986; Maug, 1998; Kahn and Winton, 1998) as well as through the threat of exit (Admati and P‡eiderer, 2009; Edmans, 2009). Empirical research, however, suggests that there is little evidence of improvement in the long-term …rm value from institutional monitoring.1 One major limitation of institutional monitoring is the free-rider problem, because institutional equity ownership is widely dispersed. As Figure 1 shows, the median value of an institution’s equity holdings in a …rm as a fraction of the …rm’s outstanding shares is 0:07% during 1980 to 2009 and decreases over the years. The di¤used institutional ownership structure suggests that, in the absence of coordination, the classical “free-rider”problem can prevail (Grossman and Hart, 1980). It has been recognized that institutions can play a more e¤ective monitoring role through coordinated activities (see, e.g., Black, 1992). Recent survey evidence of McCahery, Sautner, and Starks (2010) shows that 59% of institutional investment managers consider coordinating their actions in disciplining corporate management. Of great importance, and so far largely unexplored, is the cost of coordinating a group of institutional investors, which includes information production costs (e.g., to identify trustworthy and cooperative peers), communication and other costs incurred to reach an agreement, as well as costs associated with monitoring and enforcement of the agreement. In this paper, we examine the impact of coordination costs on the role of institutional investors in improving corporate governance and …rm value. We hypothesize that a low coordination cost improves …rm value by facilitating a stronger governance role provided by institutional investors. On the one hand, coordination costs can impact the e¤ectiveness of institutional monitoring and intervention. Although it is not cost-e¢ cient for a small shareholder to monitor managers because of the free-rider problem, low coordination costs enable dispersed institutional shareholders to conduct coordinated monitoring activities and mitigate managerial agency costs. For instance, 1 See, e.g., Gillan and Starks (2007) and Yermack (2010) for recent surveys of the literature. 1 institutions can form a shareholder coalition to sponsor proxy proposals to e¤ect changes in corporate governance (Gillan and Starks, 2000; Del Guercio, Seery, and Woidtke, 2008) as well as to engage in direct negotiation with corporate management seeking governance changes (Becht, Franks, Mayer, and Rossi, 2009). This predicts that a low coordination cost should enhance the monitoring role of institutions and lead to higher …rm valuation. On the other hand, the ease of coordination can also intensify the threat of exit. Admati and P‡eiderer (2009) argue that the threat of exit by a large shareholder can have a disciplinary impact if the shareholder possesses private information about corporate managers’ extraction of private bene…ts (and hence her trading can have an impact on the stock price on which managerial compensation is based). In the absence of coordination, institutions may be limited in using the threat of exit as a disciplinary device, because, as mentioned above, the individual equity stake by an institution is very small and because information production is costly. Thus a low coordination cost enables institutional investors to share information and to conduct coordinated selling, which can strengthen the disciplinary e¤ect of the threat of exit. This again predicts that the ease of coordination should be related to improved corporate governance and …rm value. Coordination costs are hard to observe or quantify. In this paper, we use data on institutional shareholders and construct two measures to capture the ease with which they conduct coordinated actions (in monitoring and selling). The …rst measure is the geographic distance among a …rm’s institutional shareholders. If a …rm’s institutional shareholders are geographically close to one another, they are more likely to communicate and thus coordinate their actions in major corporate events such as takeovers. This arises because geographic proximity facilitates word-of-mouth communication among professional money managers (Hong, Kubik, and Stein, 2005) and because geographic proximity can promote cooperation among agents through repeated interaction and mutual trust (Leamer and Storper, 2001). The second measure is the correlation in portfolio allocation decisions among institutional shareholders. Institutional asset managers with similar portfolio allocations are likely to form strong ties among themselves because of the homophily e¤ect. A high portfolio correlation can be the consequences of social connections as well, because institutions in the same social networks have access to the same information sources (Cohen, Frazzini, and Malloy, 2008) and because they engage in direct communication with one another (Hong, Kubik, 2 and Stein, 2005; Stein, 2008). Thus, a high portfolio correlation indicates greater homophily and stronger social ties among institutional asset managers, which should facilitate coordination. Using a comprehensive sample of stocks from 1980 to 2009, we …nd that …rm valuation (proxied by an industry-adjusted Tobin’s q) decreases with coordination costs among institutional shareholders. The economic magnitude of this e¤ect is meaningful: Moving from the 10th percentile in the geographic distance (portfolio correlation) among institutional shareholders to the 90th percentile decreases (increases) the industry-adjusted Tobin’s q by 0:055 (0:173), as compared to the median Tobin’s q of 1:29. The e¤ect is robust to controls for other institutional shareholder characteristics (such as aggregate institutional ownership, institutional ownership concentration, investment horizons of institutional shareholders, and the distance between institutional shareholders and the …rm), …rm size, growth opportunities, diversi…cation, …nancial performance, managerial ownership, and …rm-speci…c e¤ects. Furthermore, this e¤ect is driven mainly by independent institutions and non-transient institutions, both of which are more likely to play an active governance role. These results are consistent with the hypothesis that the ease of coordination among institutional shareholders enhances …rm value. Institutional investors do not randomly invest in …rms, which suggests that institutional ownership structure and hence our coordination cost measures may be endogenous. For instance, institutions that are located nearby to one another may share similar preferences and invest in high-q stocks. This will result in a reverse causality from …rm valuation to the geographic clustering of institutional shareholders. We use two approaches to address this potential endogeneity e¤ect. The …rst is an instrumental variable approach. The instruments are based on whether or not the top institutional shareholder is from New York or Boston and on the inclusion of a …rm’s stock in the Standard & Poor’s 500 index. If the top institutional shareholder of a …rm is located in cities with highly concentrated institutional asset managers, the …rm is likely to have a low coordination cost among the institutional shareholder. The addition of a stock to the S&P 500 index can attract institutions that are benchmarked against the index, thereby resulting in a more homogeneous institutional shareholder base and hence reduced coordination costs. On the other hand, it is reasonable that these instruments do not a¤ect our outcome variable through channels other than institutional ownership 3 structure. We …nd that the above relation between coordination costs and …rm value persists even after controlling for the endogeneity of coordination costs. The second is a di¤erence-in-di¤erences approach to gauge the impact of exogenous shocks on the relation between coordination costs and …rm value. We use the proxy reform in 1992 as an exogenous shock that eases coordination among shareholders. We show that the e¤ect of coordination costs on …rm value becomes signi…cantly stronger after the reform. In addition, we use the decimalization in 2001 as an exogenous shock that reduces trading costs and hence strengthens the disciplinary impact of the threat of exit. We …nd that the e¤ect becomes signi…cantly stronger after decimalization, suggesting that the threat of exit is one of the channels through which coordination cost impact …rm value. We then consider how the ease of coordination among institutional shareholders might add value by focusing on corporate governance mechanisms and governance outcomes. We …nd that …rms with low coordination costs are associated with better corporate governance, as proxied by the number of anti-takeover provisions (i.e., the G-index and the E-index). We also show that low coordination costs are associated with higher CEO equity-based pay and improved CEO turnoverperformance sensitivities. These results strengthen our interpretation that the ease of coordination enhances the role of institutional investors in corporate governance. This paper is related to two strands of empirical literature, of which the …rst is the literature on institutional monitoring. A number of studies suggest that institutional investors in‡uence corporate policies through costly monitoring or intervention (see, e.g., Hartzell and Starks, 2003; Chen, Harford, and Li, 2007; Gillan and Starks, 2000; Del Guercio, Seery, and Woidtke, 2008) as well as through the threat of exit (see, e.g., Parrino, Sias, and Starks, 2003). Much of the literature, however, implicitly treats institutional investors (or certain types of institutions) as a monolithic entity. Our paper is the …rst in the literature to study the impact of coordination costs on the role of institutional investors in improving corporate governance and …rm value. This paper also connects to the growing body of …nance literature on geography. Hong, Kubik, and Stein (2005) show that mutual fund managers located close by make similar portfolio decisions, suggesting that geographic proximity facilitates communication among professional money 4 managers. Coval and Moskowitz (1999, 2001) …nd that mutual fund managers exhibit a strong bias towards locally headquartered …rms and deliver superior returns on their local investments than distant investments, indicating an information transfer from …rm managers to mutual fund managers located nearby. Gaspar and Massa (2007) show that mutual funds located near their portfolio companies play the role of informed monitors. Kang and Kim (2007) …nd that, in partial block acquisitions, acquirer …rms tend to pursue geographically proximate targets and play a strong monitoring role in such targets post-acquisition. Our paper adds to the literature by showing that the geographic proximity among shareholders matters by a¤ecting the governance role of shareholders. The rest of the paper is organized as follows. Section 2 describes the data and summary statistics. Section 3 presents the empirical results, and Section 4 concludes. 2 Data and Summary Statistics We retrieve the data for our study from the Center for Research in Stock Prices (CRSP) database, COMPUSTAT, and Thomson Reuters’13F institutional ownership database. Our sample includes all common stocks listed on the NYSE, AMEX or NASDAQ during the period from 1980 to 2009 for which su¢ cient information is available in the three databases. There are 105; 454 …rm-year observations in the sample. We construct two measures to capture the coordination cost among institutional shareholders of a …rm. The …rst measure is based on the geographic concentration of institutional ownership. The premise is that asset managers located close to one another are more likely to come into direct contact (Hong, Kubik, and Stein, 2005) and hence to take coordinated actions. Moreover, geographic proximity can promote cooperation among institutional asset managers by facilitating repeated interaction and cultivating trust (Leamer and Storper, 2001). To construct the geographic distance measure, we …rst manually identify the location (zip code) of institutional investors using the Nelson’s Directory of Investment Managers and by searching the …lings by institutional investors on the SEC Edgar website. We then calculate, for each …rm- 5 quarter, the weighted-average geographic distance among institutional shareholders of the …rm. In particular, for each institutional shareholder in the …rm, we calculate the geographic distance between the institution and all institutions in the …rm, weighted by their respective fractional holdings in the …rm. This measure captures the average distance between an institutional shareholder and its peers. We then calculate a weighted-average of these distances across all institutional shareholders of the …rm, again weighted by their fractional holdings. This weighting scheme ensures that institutions that are likely to be more in‡uential, i.e., those with larger holdings in the …rm, receive greater weights in determining the distance among shareholders. Last, we take a simple average of the geographic distance among shareholders for each …rm over the four quarters in a year. Speci…cally, Geographic distance among institutional shareholders for …rm c = 0 13 2 4 X X X 1 4 wc;i;q l @ wc;j;q l Distij;q l A5 , (1) 4 l=1 i2S j2S where S is the set of institutional shareholders in …rm c, wc;i;t is the weight of institution i in the total percentage held by institutions in …rm c at quarter q, and Distij;t is the geographic distance between institutions i and j at quarter q. To reduce the skewness of the variable, we use the logarithm of one plus the geographic distance among institutional shareholders, Log(1 + Shareholder distance), as an explanatory variable in the regressions. The second measure is based on the portfolio correlation among institutional shareholders of the …rm. This variable is intended to capture the extent of homophily and social ties among institutional shareholders. A large body of literature on homophily in social networks suggests that individuals tend to build connections with others similar to themselves (see McPherson, Smith-Lovin, and Cook, 2001 for a review of research on homophily in social networks). Thus, institutional asset managers that share similar views about certain stocks, i.e., a high correlation in their portfolio allocations, are more likely to exhibit homophily and form strong ties among themselves, which should facilitate coordination. Moreover, a high portfolio correlation can be the consequences of social ties, because institutions in the same social networks have access to the same information sources, e.g., through shared educational ties (Cohen, Frazzini, and Malloy, 2008) and geographic 6 proximity (Coval and Moskowitz, 2001), and because they engage in direct communication with one another (Hong, Kubik, and Stein, 2005; Stein, 2008). To the extent that the portfolio correlation measure captures homophily and social connectedness among institutional asset managers, it should be negatively related to shareholder coordination costs. To construct the portfolio correlation measure, we retrieve the entire portfolio holdings of all institutional shareholders of our sample …rms in each quarter. For each pair of institutional shareholders, we calculate the correlation coe¢ cient of the excess portfolio weights on common holdings, i.e., stocks that are held by both institutions.2 The excess portfolio weights are calculated as the actual portfolio weight assigned to a stock relative to the weight of the stock in the market portfolio. We use the excess portfolio weights, rather than the actual weights, to focus on active portfolio allocation decisions of institutional asset managers. Similar to the construction of the geographic distance variable, we …rst calculate, for each institutional shareholder, the portfolio correlation between the institution and all institutions in the …rm, weighted by their respective fractional holdings. We then calculate the weighted-average of these correlations across all institutional shareholders, again weighted by each institution’s fractional holdings in the …rm. We take a simple average of the institutional portfolio correlation for the stock over four quarters in a year. Speci…cally, Portfolio correlation among institutional shareholders for …rm c = 2 0 13 4 X X X 1 4 wc;i;q l @ wc;j;q l Corrij;q l A5 , (2) 4 l=1 i2S j2S where S is the set of institutional shareholders in …rm c, wc;i;t is the weight of institution i in the total percentage held by institutions in …rm c at quarter q, and Corrij;t is the correlation coe¢ cient of the excess portfolio weight (measured as the actual weight relative to the weight in the market portfolio) allocated to overlapping holdings between institutions i and j at quarter q. Panel A of Table 1 presents summary statistics for the two measures of shareholder coordination costs for all sample …rms. The average geographic distance among institutional shareholders is 2 If two institutions have less than …ve common holdings, we set the correlation to zero. The results are robust to using a di¤erent cuto¤ or setting it to missing. 7 878:1 miles.3 The average portfolio correlation among institutional shareholders is 0:30. Both of the coordination cost measures exhibit a fair degree of cross-sectional variation across …rms. Panel A of Table 1 also presents summary statistics for other shareholder characteristics and …rm characteristics. In particular, since institutions located close to their portfolio companies are likely to play a monitoring role (Gaspar and Massa, 2007; Chhaochharia, Kumar, and Niessen, 2009), we calculate the weighted-average geographic distance between institutional shareholders and …rms, weighted by institutions’fractional holdings. The average distance between institutional investors and the …rm is 945:9 miles. Institutional shareholders, in aggregate, own 33% of the outstanding shares of the average …rm. Following Hartzell and Starks (2003), we calculate institutional ownership concentration as a Her…ndahl Index of institutional ownership concentration based on the percentages of institutional holdings by all 13F institutions. The average institutional ownership concentration for the …rms is 0:012. Following Gaspar, Massa, and Matos (2005), we calculate shareholder turnover of a …rm as the weighted-average of the average total portfolio turnover rate of the …rm’s institutional shareholders. The average shareholder turnover rate for the …rms is 0:27. We calculate Tobin’s q as the ratio of market value of assets to book value of assets, where market value of assets is measured as the market value of common equity plus the book value of preferred stock (carrying value) plus the book value of long-term debt minus deferred taxes and investment tax credit.4 The industry-adjusted Tobin’s q is calculated as the di¤erence between the …rm’s Tobin’s q and its industry median using the three-digit SIC code (McConnell and Servaes, 1990). The mean Tobin’s q is 1:83, and the mean industry-adjusted Tobin’s q is 0:30. Panel B of Table 1 presents a correlation matrix of the main variables. The two coordination cost proxies are highly negatively correlated, with a correlation coe¢ cient of 0:786, suggesting that institutional shareholders located close to one another tend to have correlated portfolio allocations. This is consistent with the “word-of-mouth” e¤ect documented by Hong, Kubik, and Stein 3 The magnitude of this distance appears large. However, it should be noted that it is measured across all institutions that hold shares in the …rm. Consider a hypothetical …rm with 50 institutional shareholders from the 50 states in the U.S. (assuming they are located in the state capitals), each holding 2% of the …rm’s outstanding shares. The shareholder distance for the …rm would be 1; 822 miles. Thus, the seemingly large distance among institutions is driven mainly by the fact that the U.S. is geographically large. 4 A more sophisticated approach to estimating Tobin’s q is to calculate the replacement cost of assets (Lindenberg and Ross, 1981). We use the simple approach, instead of the more sophisticated one because the latter requires arbitrary assumptions about depreciation and in‡ation rates and because the two approaches deliver highly correlated estimates of Tobin’s q (Villalonga and Amit, 2006). 8 (2005). Furthermore, both Tobin’s q and industry-adjusted Tobin’s q are signi…cantly negatively correlated with the geographic distance measure, and both are signi…cantly positively correlated with the portfolio correlation measure. These results give a preliminary indication that the ease of coordination cost may improve …rm value. In addition, we retrieve various corporate goverance-related variables, such as managerial ownership, board characteristics, and executive compensation, from RiskMetrics and ExecComp. We report the summary statistics as well as the correlation matrix for these variables in Table 1. [Insert Table 1 about here] 3 Empirical Results 3.1 Coordination Costs and Firm Value In this section, we …rst examine the relation between …rm value and coordination costs using …rm…xed e¤ects regressions. We then address endogeneity concerns by using an instrumental variable approach and by using a di¤erence-in-di¤erences approach to gauge the impact of two exogenous shocks. Last, we conduct robustness checks of the regression results. 3.1.1 Firm-…xed E¤ects Regressions To examine the e¤ects of coordination costs on …rm valuation, we run …rm-…xed e¤ects regressions of industry-adjusted Tobin’s q on our coordination costs proxies and control variables. We lag all our explanatory variables by one year to mitigate any confounding e¤ects due to contemporaneous measurement. Speci…cally, q j;t = + j + Coordination Costs j;t 1 + X i xi;j;t 1 where q j;t is …rm j’s industry-adjusted Tobin’s q at the end of year t, ordination Costs j;t 1 j + "j;t , is …rm-…xed e¤ects, Co- is one of the two measures of coordination costs for …rm j in year t 9 (3) 1, and xi;j;t 1 includes standard control variables for Tobin’s q such as …rm size, pro…tability, capital ex- penditure, leverage, R&D expenses, institutional ownership, institutional ownership concentration, investment horizons of institutional shareholders, the distance between institutional shareholders and the …rm, and year dummies. We cluster the standard errors at the …rm level (Petersen, 2009). As Panel B of Table 1 shows, the two coordination cost proxies are highly negatively correlated, we include them in the regressions one at a time. The regression results, shown in Panel A of Table 2, indicate that the ease of coordination has a positive e¤ect on …rm value. The economic magnitude of this e¤ect is meaningful: Based on the full speci…cation (i.e., the last two columns of Table 2, Panel A), moving from the 10th percentile in the geographic distance (portfolio correlation) among institutional shareholders to the 90th percentile decreases (increases) the industry-adjusted Tobin’s q by 0:055 (0:173), as compared to the median Tobin’s q of 1:29. Since institutions may di¤er in their incentives and abilities to play a governance role, we partition institutional investors into groups in two di¤erent ways. First, we classify institutions into independent institutions and “grey” institutions following Chen, Harford, and Li (2007). Independent institutions include investment companies, independent investment advisors, and public pension funds, which do not have business relationships with their portfolio companies and hence are more likely to engage in active monitoring. Grey institutions include insurance companies, banks, and private pension funds, which are less likely to play a governance role because of their business ties with the …rms they invest in. Second, we divide institutions into transient and non-transient categories following Bushee (1998). Non-transient institutions are dedicated and quasi-indexer based on Bushee’s de…nition, which are likely to be more e¤ective monitors. We expect that the e¤ect of coordination costs on …rm value should be driven mainly by independent institutions and non-transient institutions. We reconstruct the coordination cost measures separately for each category of institutions. We replace the aggregate coordination cost measures in Eq. (3) with separate coordination cost measures for each category of institutions, and re-estimate the regressions. Panel B of Table 2 reports the results. Consistent with our expectation, the negative e¤ects of coordination costs on …rm value are driven mainly by independent institutions and by non-transient institutions. 10 We further add control variables related to managerial ownership and board structure in our …rm-…xed e¤ects regressions to examine whether the negative relation between Tobin’s q and coordination costs are driven by these factors. In particular, we include managerial ownership, managerial ownership squared, indicator variables for small boards (board size less than 9), independent boards (independent outside directors account for more than 75% of the board), and CEO/Chairman duality. The sample size for these variables is 31; 559, about a third of our sample size in the baseline regressions. The results, reported in the last two columns of Table 2, Panel B, suggest that the negative e¤ects of coordination costs on …rm value are robust to adding these controls. The coe¢ cient on managerial ownership is positive and signi…cant, whereas that on managerial ownership squared is negative and signi…cant. These results are consistent with an inverted U-shaped relation between Tobin’s q and managerial ownership (e.g., Morck, Shleifer, and Vishny, 1988). [Insert Table 2 about here] 3.1.2 Addressing Endogeneity Concerns The panel regression results presented above may raise endogeneity concerns, because institutional investors do not invest randomly. For instance, institutions that are located nearby to one another may share similar preferences and invest in high-q stocks. This will result in a reverse causality from …rm valuation to the geographic clustering of institutional shareholders. We use two approaches to address this potential endogeneity e¤ect. The …rst is an instrumental variable approach, and the second is to exploit regulatory changes as exogenous shocks to shareholder coordination. A. Instrumental Variable Regressions. We use two instruments. The …rst is an indicator variable for whether the largest institutional shareholder is headquartered in New York City and Boston. Intuitively, if the top institutional shareholder is from a city with highly concentrated institutional investment managers, the institution can more easily coordinate with other institutional shareholders, because they are likely to be located in the same city and hence share similar portfolio allocations (Hong, Kubik, and Stein, 2005). This should lead to a lower coordination cost for the …rm. We use metropolitan statistical areas (MSAs) to de…ne the location of institutional asset 11 managers. We choose New York and Boston, because these two cities dominate the institutional asset management landscape, representing 19:3% and 16:0% of the total dollar holdings by all 13F institutions, respectively. We indentify the largest institutional shareholder of a …rm at the start of year t 1, i.e., 24 months prior to measuring Tobin’s q, based on holdings in the …rm’s stock. The exclusion restriction for an instrument— that it should not directly a¤ect or be directly a¤ected by the dependent variable— is also satis…ed, since the change in the fundamental value of a …rm should not be directly related to whether or not the …rm’s the top institutional shareholder is located in New York or Boston. The second is an indicator variable for S&P 500 index inclusion that equals one if the stock is included in the S&P 500 index in year t 1 and zero otherwise. The addition of a stock to the S&P 500 index can attract institutions that are benchmarked against the index, thereby resulting in a more homogeneous institutional shareholder base and hence reduced coordination costs. The reverse is true for index deletions. On the other hand, the S&P500 inclusion or deletion seems to satisfy the exclusion restriction for a valid instrument, because a large literature contends that index inclusion is unrelated to any change in the fundamental performance of the included stock (see, e.g., Shleifer, 1986; Kaul, Mehrotra, and Morck, 2000).5 We use the two-stage least square (2SLS) procedure to account for the endogeneity of coordination costs. In the …rst stage, we regress coordination costs measures on the two instruments and other exogenous variables. In the second stage, we run a regression of the industry-adjusted Tobin’s q on the …tted values from the …rst stage regression as the instrument for coordination costs. Speci…cally, we estimate the following 2SLS model: First Stage: Coordination Costs j;t Second Stage: q j;t = where NYC/Boston j;t + 1 j 1 = c+ j + NYC/Boston j;t 1+ + Instrumented Coordination Costs j;t S&P500 j;t 1 + P P 1+ i=1;k #i xi;j;t 1 + j;t 1 i=1;k i xi;j;t 1 + "j;t (4) is an indicator variable that equals one if stock j ’s largest institutional shareholder as of the start of year t 1 is located in New York or Boston and zero otherwise; 5 Standard and Poor’s explicitly states that “the decision to include a company in the S&P 500 Index is not an opinion on that company’s investment potential.” 12 S&P500 j;t 1 is an indicator variable that equals one if stock j is included in the S&P 500 index in year t 1 and zero otherwise; Instrumented Coordination Costs j;t coordination costs measures from the …rst-stage regressions, j and j 1 is the …tted value of the are …rm-…xed e¤ects, xi;j;t 1 is the same set of control variables as in Eq. (3). Table 3 report the results from the 2SLS model. Columns 1 and 2 of Table 3 reports the results of the …rst-stage regression with the dependent variable being one of the two measures of coordination costs. Consistent with economic intuition, …rms whose largest institutional shareholder is from New York or Boston are associated with signi…cantly lower coordination costs, i.e., a smaller geographic distance and a higher portfolio correlation, among the institutional shareholders. Moreover, the addition of a stock to the S&P 500 index has a signi…cant negative e¤ect on the coordination costs among institutions. These e¤ects are economically signi…cant as well. For instance, the geographic distance among institutions decreases by 5:7% if the stock’s largest institutional shareholder switches from a non-New York/Boston institution to a New York/Boston one; the geographic distance among institutions decreases by 26:1% when the stock is added to the S&P 500. We conduct F -tests of joint signi…cance of the two instruments. The F -statistics strongly reject the null hypothesis that our instruments are irrelevant in the …rst-stage regressions. We also conduct the Stock and Yogo (2005) weak instrument test of the null hypothesis that the instruments are only weakly correlated with the endogenous variables. The test strongly rejects the null hypothesis that the instruments are weak. We report these test statistics at the bottom of Table 3. Columns 3 and 4 of Table 3 report the second-stage results with industry-adjusted Tobin’s q as the dependent variable. Consistent with our baseline results from …rm-…xed e¤ects regressions, the coe¢ cient estimates of the instrumented coordination costs measures remain signi…cant (at the 5% level) and in the predicted directions. The absolute magnitude of these coe¢ cient estimates appears greater than those obtained using …rm-…xed e¤ects regressions. Since we use two instruments for each of the coordination costs variables, we have an overidenti…ed speci…cation. We conduct the Hansen overidenti…cation test. The Hansen J -statistics cannot reject the joint null hypothesis that the instruments are uncorrelated with the error term and are correctly excluded from the second-stage regressions. 13 Overall, the 2SLS regression results suggest that the impact of coordination costs on Tobin’s q is not driven by the endogenous selection of high-q …rms by coordinated institutions. [Insert Table 3 about here] B. The E¤ect of the 1992 Proxy Reform. We now exploit the 1992 proxy reform as an exogenous shock that reduced the barriers to shareholder coordination in corporate governance (Choi, 2000; Bradley, Brav, Goldstein, and Jiang, 2010). Prior to the October 1992 changes to the proxy rules, any communication among a group of 10 shareholders or more under circumstances reasonably calculated to a¤ect voting decisions would amount to proxy solicitation and was not allowed until a formal proxy statement was delivered to other shareholders. This communication restriction was eased with the 1992 proxy reform such that any communication by shareholders not directly seeking the power to vote as proxy for other shareholders was excluded from the de…nition of what constitutes a solicitation. The reform thus signi…cantly eased communication and coordination among shareholders. This predicts that the e¤ects of coordination costs on …rm value should become stronger in the post-reform period. We use a di¤erence-in-di¤erences approach to examine the impact of the 1992 reform on the relation between coordination costs and …rm value. We use a two-year window and de…ne the …scal year in which the reform occurred as year t. We choose year t 2 for the pre-reform period, and year t as the post-reform period. We discard the year immediately before the reform, i.e., year t 1, because the reform was widely discussed in the media before the …nal adoption of the changes and, as such, …rm value in year t 1 may have factored in the e¤ect associated with coordination costs. In addition, because we are interested in the e¤ect of proxy reform on coordination costs and …rm value, we require that each stock be present in both windows around the reform. As a result, for every stock we note only two observations— one in each window of the event. We divide the sample of stocks into quintiles based on each of the coordination costs proxies. Stocks in the bottom quintile of coordination costs constitute a “treatment”group that experiences an exogenous shock to shareholder coordination. Stocks in the top quintile constitute the control group. Intuitively, the reform signi…cantly reduces the restrictions on shareholder coordination, thereby enabling institutions with low coordination costs to conduct coordinated monitoring activ14 ities. In contrast, the reform should have little, if any, impact on …rms whose institutional shareholders face prohibitively high coordination costs, because the institutions are likely to remain passive post-reform due to the high coordination costs. By comparing the change in industry-adjusted Tobin’s q after the reform for the treatment and control groups, we allow for both group-speci…c and time-speci…c e¤ects. Panels A and B of Table 4 present the results of univariate di¤erence-in-di¤erences comparisons in industry-adjusted Tobin’s q between low- and high-coordination-cost …rms before and after the proxy reform. The di¤erence-in-di¤erences estimator indicates a large increase in industry-adjusted Tobin’s q for …rms with low coordination costs relative to those with high coordination costs after the reform. In particular, Panel A shows that …rms in the bottom quintile of the geographic distance among the institutional shareholders (the treatment sample) experience an increase of 0:11 in industry-adjusted Tobin’s q, compared to a change of 0:01 for …rms in the top quintile. The di¤erence in the change in industry-adjusted Tobin’s q between the two groups, albeit not statistically signi…cant, is economically large. Panel B shows that when the portfolio correlation measure is employed as the coordination cost proxy, the di¤erence-in-di¤erences estimator suggests an increase in industry-adjusted Tobin’s q of 0:15 (signi…cant at the 5% level) for the treatment …rms relative to the control …rms. To control for the e¤ect of other factors that may a¤ect …rm value, we estimate multivariate di¤erence-in-di¤erences regressions on the two-year sample around the reform. In particular, we add an indicator variable, Post-reform, which equals one for observations after October 1992, and zero otherwise. We interact our coordination costs variables with the post-reform dummy; the coe¢ cient on the interaction term captures the di¤erence-in-di¤erences e¤ect of the reform on …rms with low coordination costs relative to those with high coordination costs. Panel C of Table 4 presents the results of the di¤erence-in-di¤erences regressions. In all four speci…cations, the coe¢ cient on the interaction between the coordination costs variables and the post-reform dummy is signi…cant at the 1% level and in the predicted directions. For instance, Column 2 shows that, after controlling for other factors that a¤ect industry-adjusted Tobin’s q, the e¤ect of the geographic distance among institutions on industry-adjusted Tobin’s q is signi…cantly more negative after the reform as compared to before. These results are consistent with our 15 univariate results, indicating a causal e¤ect of coordination costs on …rm value. [Insert Table 4 about here] C. The E¤ect of Decimalization. Institutions can coordinate their selling behavior and use the threat of exit as a disciplinary device. Admati and P‡eiderer (2009) contend that a liquid stock market, i.e., lower transaction costs, can improve the e¤ectiveness of the threat of exit as a corporate governance mechanism. We use decimalization as an exogenous shock that increases stock market liquidity, which in turn can intensify the disciplinary e¤ect of the coordinated threat of exit. The stock markets in the U.S. converted to the decimal-pricing system and reduced the minimum tick size from a sixteenth of a dollar to one cent during the period between August 2000 and April 2001. This led to signi…cant drops in bid-ask spreads following decimalization (Bessembinder, 2003; Fur…ne, 2003). Institutional investors, due to their sizable holdings, are sensitive to transaction costs.6 Other things equal, …rms whose institutional shareholders face lower coordination costs should be more likely to coordinate and use the threat of exit to discipline corporate managers postdecimalization, compared to …rms with widely dispersed institutional shareholders. This predicts that the e¤ects of coordination costs on …rm value should become stronger following decimalization. We estimate multivariate di¤erence-in-di¤erences regressions on a two-year sample around decimalization. In particular, we de…ne the …scal year in which decimalization occurred as year t. We choose year t 1 for the pre-decimalization period, and year t as the post-decimalization period. We add an indicator variable, Post-decimalization, which equals one for observations after January 2001, and zero otherwise. We interact our coordination costs variables with the post-decimalization dummy; the coe¢ cient on the interaction term captures the di¤erence-in-di¤erences e¤ect of decimalization on …rms with low coordination costs relative to those with high coordination costs. Table 5 presents the results of the di¤erence-in-di¤erences regressions. The coe¢ cients on the interaction between the coordination costs variables and the post-reform dummy are all in the predicted directions and generally signi…cant. These results suggest that the threat of exit is one of the channels through which coordination costs a¤ect …rm value. 6 For example, Wermers (2000) …nds that 0:8% of the 2:3% performance di¤erence between mutual funds’ gross returns and net returns is due to transaction costs. 16 [Insert Table 5 about here] 3.1.3 Robustness Checks In this section, we conduct a series of robustness checks on the relation between …rm valuation and coordination costs. A. Controlling for local institutions. Investors located close to their investments are likely to have an informational advantage (Coval and Moskowitz, 2001; Baik, Kang, and Kim, 2010) as well as to provide a strong monitoring role (Gaspar and Massa, 2007; Kang and Kim, 2008). To test whether the …ndings are driven by local institutional shareholders, we reconstruct the two measures of shareholder coordination costs by excluding institutional investors located within 100 kilometers of the …rm’s headquarter and re-estimate Eq. (3). The results, reported in the …rst two columns of Table 6, show that the e¤ects of coordination costs on …rm value are qualitatively unchanged, suggesting that the results are not driven by local institutions. B. Excluding cities with highly concentrated institutional investors. Institutional asset management is highly geographically concentrated. One concern is that the …ndings are driven by a few cities with a high concentration of institutional investors. We thus repeat the analysis by excluding these cities. We use metropolitan statistical areas (MSAs) to de…ne the location of institutional asset managers. For each MSA and each quarter, we calculate the total dollar value of equity holdings that are managed by institutions residing in that MSA. New York and Boston dominate the institutional asset management landscape, representing 19:3% and 16:0% of the total dollar holdings by all 13F institutions, respectively. We then construct the two measures of shareholder coordination costs by excluding the two MSAs and re-estimate Eq. (3). Columns 3 and 4 of Table 6 show that the results are again qualitatively unchanged. This …nding suggests that the results are not driven by the two extreme cities per se. C. Excluding foreign institutions. The fraction of the total institutional equity holdings in the U.S. managed by foreign institutions has increased signi…cantly from 3% in 1980 to 15% in 2008. On the one hand, the presence of foreign institutions can increase the geographic distance among shareholders and, to the extent that they have di¤erent investment objectives from domestic 17 institutions, decrease the portfolio correlation among the institutional shareholders of a …rm. On the other hand, foreign institutions might be less e¤ective in monitoring management than domestic institutions due to geographic distance (Kang and Kim, 2008). To test whether the results are driven by foreign institutions, we reconstruct the two measures of shareholder coordination costs by excluding foreign institutions and re-estimate Eq. (3). The results, reported in Columns 5 and 6 of Table 6, are essentially unchanged compared to the baseline results reported in Table 2, Panel A, which suggests that foreign institutions do not drive the results. D. OLS regressions with lagged dependent variables. We estimate OLS regressions adding lagged industry-adjusted Tobin’s q as a control variable. The last two columns of Table 6 report the results. As expected, the coe¢ cient on the lagged industry-adjusted Tobin’s q is positive and highly signi…cant. The coe¢ cients on our key variables, i.e., the coordination costs variables, remain signi…cant and in the predicted directions. Furthermore, our results are robust to adding two or three lags of industry-adjusted Tobin’s q in the OLS speci…cation. [Insert Table 6 about here] 3.2 Coordination Costs and Corporate Governance We now consider how the ease of coordination among institutional shareholders might add value by focusing on corporate governance mechanisms and governance outcomes. 3.2.1 Anti-takeover Provisions A large literature in corporate governance suggests that anti-takeover provisions have a negative impact on …rm value by insulating corporate managers from the external discipline of takeovers (e.g., Gompers, Ishii, and Metrick, 2003; Bebchuck, Cohen, and Ferrell, 2009). If coordination costs are low, a coalition of institutional shareholders can in‡uence the use of anti-takeover provisions by corporations by coordinating their actions. For example, institutional shareholders can jointly propose and vote on governance issues, such as removing anti-takeover provisions, in annual shareholder meetings. This predicts that the ease of coordination among institutions should be related 18 to a lower number of anti-takeover provisions. We use two indices to measure the level of external corporate governance. The …rst is the Gindex proposed by Gompers, Ishii, and Metrick (2003), which is based on 24 anti-takeover provisions. The second is the entrenchment index (E-index) proposed by Bebchuck, Cohen, and Ferrell (2009). The entrenchment index consists of six provisions, namely classi…ed boards, limits to shareholder bylaw amendments, poison pills, golden parachutes, and supermajority requirements for mergers and charter amendments. For both indices, a low number indicates strong corporate governance. We estimate multivariate regressions of the corporate governance indices on coordination costs and control variables. Speci…cally, Governance Index j;t = + $Coordination Costs j;t 1 + X i xi;j;t 1 + j;t , (5) where Governance Index j;t is one of the two corporate governance indices for …rm j in year t; Coordination Costs j;t 1 is one of the two measures of coordination costs among institutional share- holders of …rm j in year t 1; and xj;t 1 includes year and industry …xed e¤ects, …rm characteristics, and other ownership characteristics of …rm j in year t 1. Table 7 reports the results. In three out of four speci…cations, the coordination costs variables are signi…cant and in the predicted directions. The economic magnitude is large as well: for instance, moving from the 10th to the 90th percentiles in the geographic distance (portfolio correlation) variable increases (decreases) the G-index by 0:71 (4:04), compared to the median G-index of 9. These results suggest that the ease of coordination enables institutional shareholders to play a stronger monitoring role by removing barriers to takeovers. [Insert Table 7 about here] 3.2.2 Equity-based Incentives An extensive literature suggests that equity-based compensation for corporate managers can improve …rm performance (e.g., Mehran, 1995). Hartzell and Starks (2003) suggests that institutional investors can enhance the pay-for-performance sensitivity of managers through increased monitor19 ing. We hypothesize that institutional investors, through coordinated monitoring, can improve corporate governance by increasing corporate managers’equity-based incentives. We use two measures to capture the equity-based incentives of CEOs. The …rst measure is the incentive ratio proposed by Bergstresser and Philippon (2006). This ratio employs the total holding of stock and options rather than annual grants, and is de…ned as follows: Incentive ratio = Increase in value of CEO stock and options for a 1% increase in stock price Increase in value of CEO stock and options + annual salary + annual bonus (6) where the numerator is calculated as 0.01 multiplied by the product of the …rm’s share price and the number of shares and options held by the CEO. The second measure is the option fraction as in Mehran (1995), which is calculated as the percentage of total CEO annual compensation comprised of grants of new stock options, with the options valued by the Black-Scholes formula. Data on option grants, salary, bonus, and other compensation are available from Standard and Poor’s ExecuComp database, available through Compustat. We estimate multivariate regressions of the equity-based incentives on coordination costs and control variables using a speci…cation similar to Eq. (5). Table 8 reports the results. In all four speci…cations, the coordination costs variables have the predicted signs, although only two are signi…cant at the 1% level. These results suggest that a low coordination cost enables institutional shareholders to in‡uence compensation policies that enhance shareholder value. [Insert Table 8 about here] 3.2.3 Turnover-performance Sensitivity A primary outcome of internal monitoring by shareholders and board of directors is CEO turnover (Huson, Parrino, and Starks, 2001). Coordinated monitoring by institutional investors can exert pressure on the …rm’s board of directors to identify and terminate incompetent CEOs. We explore this possibility by testing whether the ease of coordination enhances CEO turnover-performance sensitivity. 20 We extract data from the ExecuComp database to identify CEO turnover. We classify a …rm as having experienced a CEO turnover when the CEO in year t is di¤erent from the CEO in year t 1. We identify 2; 851 (11:8%) CEO turnover events out of 24; 228 …rm-years during the period from 1993 to 2009. We then run probit regressions to examine the in‡uence of coordination costs on the likelihood of CEO turnover. Speci…cally, P rob(Turnover j;t ) = + (Coordination Costs j;t + Coordination Costs j;t 1 Stock Return j;t 1 + Stock Return j;t 1 1) + X i xi;j;t 1 + j;t , (7) where Turnover j;t is an indicator variable that equals one if the CEO of …rm j in year t is di¤erent from the CEO in year t 1; Coordination Costs j;t 1 is one of the two measures of coordination costs among institutional shareholders of …rm j in year t return of …rm j’s stock in year t 1; and xi;t 1 1; Stock Return j;t 1 is the buy-and-hold includes …rm- and manager-level characteristics as well as other shareholder characteristics of the …rm. The managerial characteristics we consider are whether the CEO is above the age of 60, whether the CEO is also the chairman of the board, and CEO tenure. The results, reported in the …rst two columns of Table 9, show that the interaction between the geographic distance variable and stock return has a positive and signi…cant (at the 5% level) coe¢ cient, which suggests that the ease of coordination improves the CEO turnover-performance sensitivity. The result using the portfolio correlation variable is insigni…cant. We then create dummy variables for the two coordination costs measures. Geographically concentrated is an indicator variable that equals one if the geographic distance among institutions is in the bottom quartile and zero otherwise. Correlated portfolio is an indicator variable that equals one if the portfolio correlation among institutions is in the top quartile and zero otherwise. We replace each of the coordination costs variables with the respective indicator variables and re-estimate Eq. (7). The results, reported in Columns 3 and 4 of Table 9, show that the coe¢ cients on the interaction terms are signi…cant and in the expected directions. The results lend support to our prediction that the ease of coordination among institutional shareholders is associated with an increased propensity to terminate poorly performing CEOs. 21 [Insert Table 9 about here] 4 Conclusion The ease of coordination has an important impact on the role of institutional investors in corporate governance. Using measures based on the geographic distance among institutional shareholders and their portfolio correlation to measure coordination costs, we …nd that …rm value as measured by industry-adjusted Tobin’s q decreases with coordination costs. This e¤ect is robust to controls for other institutional shareholder characteristics (such as aggregate institutional ownership, institutional ownership concentration, investment horizons of institutional shareholders, and the distance between institutional shareholders and the …rm), …rm size, growth opportunities, diversi…cation, …nancial performance, managerial ownership, and …rm-speci…c e¤ects. Furthermore, this e¤ect is driven mainly by independent institutions and non-transient institutions, both of which are more likely to play an active governance role. We address endogeneity concerns by using an instrumental variable approach and by exploiting two exogenous shocks to shareholder coordination. The e¤ect of coordination costs on …rm value still holds after controlling for the endogeneity of institutional ownership structure. We also …nd that the change in industry-adjusted Tobin’s q after the 1992 proxy reform is signi…cantly greater for …rms with low coordination costs. Furthermore, the change in industry-adjusted Tobin’s q after decimalization is signi…cantly greater for …rms with low coordination costs. These results provide further evidence for the causal e¤ect of coordination costs on …rm value. Last, we show that the ease of coordination among institutions is associated with fewer antitakeover provisions adopted by the …rm, higher equity-based pay for CEOs, and improved CEO turnover-performance sensitivities. Overall, these …ndings suggest that the ease of coordination enhances the governance role of institutional shareholders. This paper contributes to our understanding of institutional monitoring. While the existing literature implicitly treats institutional investors (or certain types of institutions) as a monolithic entity, the di¤use nature of institutional shareholding suggests that coordination among institutions 22 is necessary to limit the free-rider problem. The evidence in this paper highlights the importance of coordination costs in determining the intensity of institutions’monitoring. 23 References [1] Admati, Anat R., and Paul P‡eiderer, 2009, The “Wall Street Walk”and shareholder activism: Exit as a form of voice, Review of Financial Studies 22, 2645–2685.

Table 1: Summary statistics of shareholder coordination costs and other firm characteristics This table reports the summary statistics and correlation matrix of various firm characteristics, including coordination costs among institutional shareholders, institutional ownership, firm valuation, corporate governance structure, and executive compensation and turnover. Shareholder distance is the weighted-average geographic distance among institutional shareholders over the four quarters in a year as given in Eq. (1). Log(1+Shareholder distance) is the logarithm of one plus Shareholder distance. Shareholder portfolio correlation is the weighted-average correlation coefficient of the portfolio weights (relative to the weight in the market portfolio) on common holdings between each pair of institutional shareholders of the firm over the four quarters in a year as given in Eq. (2). Tobin’s q is measured as the market value of common equity plus the book values of preferred equity and long-term debt minus deferred taxes and investment tax credit, all scaled by the book value of assets [COMPUSTAT items (fyme+prf+lt–txditc)/at]. The industry-adjusted Tobin’s q is calculated as the difference between the firm’s Tobin’s q and its industry median using the three-digit SIC code (McConnell and Servaes, 1990). Inst. ownership is the fraction of shares outstanding held by institutional investors. Inst. ownership concentration is calculated as a Herfindahl Index of institutional ownership concentration based on the percentages of institutional holdings by all 13F institutions (following Hartzell and Starks, 2003). Shareholder-firm distance is measured as the weighted-average geographic distance between the firm and its institutional shareholders. Shareholder turnover is the weighted-average of the average total portfolio turnover rate of the firm’s institutional shareholders (following Gaspar, Massa, and Matos, 2005). Return on Assets is the ratio of operating income become depreciation to total assets (COMPUSTAT items oibdp/at). Firm size is the logarithm of total assets [COMPUSTAT item log(at)]. Book leverage is the ratio of total debt to the book value of total assets [COMPUSTAT items (at–be)/at]. R&D/Sales is the ratio of R&D expenses to total sales [COMPUSTAT items xrd/sale]. Asset tangibility is the ratio of net property, plant, and equipment to the book value of total assets [COMPUSTAT items ppent/at]. CapEx/Assets is the ratio of capital expenditure to the book value of total assets [COMPUSTAT items capx/at]. Number of geographic segments is the number of geographic segments in the firm. G-Index is the number of takeover defenses as proposed by Gompers, Ishii, Metrick (2003). E-Index is the entrenchment index based on six provisions: staggered boards, limits to shareholder bylaw amendments, poison pills, golden parachutes, and supermajority requirements for mergers and charter amendments as proposed by Bebchuk, Cohen, and Ferrell (2009). Board size is the number of directors on the board. Board independence is the proportion of the board composed of independent outside directors. CEO/Chairman duality is an indicator variable which equals one if the titles of CEO and Chairman are vested in the same individual and zero otherwise. Managerial stock ownership is the fraction of outstanding shares owned by top five executives of the firm. CEO incentive ratio is the ratio of the increase in value of CEO stock and options for a 1% increase in stock price to the sum of the increase in value of CEO stock and options and annual salary and bonus as proposed by Bergstresser and Philippon (2006). CEO option fraction is the fraction of CEO total compensation composed of option awards based on Black-scholes value. CEO turnover is an indicator variable which equals one if the CEO in year t+1 for the firm is not the same as in year t. Panel A presents the summary statistics, and Panel B presents the correlation matrix for the main variables. In Panel B, the numbers in bold are significantly different from zero at the 1% level.

The dependent variable is industry-adjusted Tobin’s q. Panel A reports the results from baseline regressions. Panel B reports the results using alternative specifications. In particular, columns 1 and 2 in Panel B include as regressors separate measures for the coordination costs among independent institutions and grey institutions (Chen, Harford, and Li, 2007). Similarly, columns 3 and 4 in Panel B include as regressors separate measures for the coordination costs among transient institutions and non-transient institutions (Bushee, 1998). The last two columns in Panel B include managerial ownership and board characteristics as additional controls. Small board is an indicator variable that equal one if the board size is less than 9, and zero otherwise. Independent board is an indicator variable that equal one if independent outside directors account for more than 75% of the board, and zero otherwise. See Table 1 for the definition of the variables. Year fixed effects and firm fixed effects are included in all regressions. Numbers in parentheses are t-statistics based on robust standard errors clustered at the firm level. Significance on a 10% (*), 5% (**), or 1% level (***) is indicated.

(4). We use two instruments. The first is Top institution located in NYC/Boston, which is an indicator variable that equals one if the stock’s largest institutional shareholder as of the start of year t−1 is located in New York or Boston and zero otherwise. The second is S&P 500 index inclusion, which is an indicator variable that equals one if the stock is included in the S&P 500 index in year t−1 and zero otherwise. The left panel reports the results from the first-stage regressions with coordination costs proxies as the dependent variable. The right panel reports the results from the second-stage regressions of industryadjusted Tobin’s q on instrumented coordination costs and control variables. See Table 1 for the definition of the variables. Year fixed effects and firm fixed effects are included in all regressions. We report at the bottom of the table the F-statistics of the test for the joint significance of the instruments in the first stage, the Wald statistics for Stock and Yogo (2005) weak instrument tests of the null hypothesis that the instruments are only weakly correlated with the endogenous variables, and the Hansen Jstatistics for overidentifying restrictions. Numbers in parentheses are t-statistics based on robust standard errors clustered at the firm level. Numbers in square brackets are p-values.

We use a two-year window and define the fiscal year in which the reform occurred as year t. We choose year t−2 for the pre-reform period, and year t as the post-reform period. We require that each stock be present in both windows around the reform. We divide the sample of stocks into quintiles based on each of the coordination costs proxies. Stocks in the bottom quintile of coordination costs, i.e., Geographically concentrated and Correlated portfolios, constitute a “treatment” group that experiences an exogenous shock to shareholder coordination. Stocks in the top quintile, i.e., Geographically dispersed and Uncorrelated portfolios, constitute the control group. Panels A and B present the results of univariate difference-in-differences comparisons in industry-adjusted Tobin’s q between low- and high-coordination-cost firms before and after the proxy reform. Panel C presents the results of multivariate difference-in-differences regressions. The dependent variable is industry-adjusted Tobin’s q. See Table 1 for the definition of the variables. Numbers in parentheses are t-statistics based on robust standard errors clustered at the firm level. Significance on a 10% (*), 5% (**), or 1% level (***) is indicated.

The dependent variable is industry-adjusted Tobin’s q. For all the tests except models 7 and 8, we use the same set of firm-level control variables as in Table 2. The coefficient estimates for the control variables are not reported to conserve space. The first two columns report the results when local institutions, i.e., those located within 100 kilometers of the firm, are excluded in constructing the coordination cost measures. Columns 3 and 4 report the results when institutions located in New York and Boston are excluded. Columns 5 and 6 report the results when foreign institutions are excluded. Columns 7 and 8 report the OLS regression results with industry adjusted Tobin’s q in year t−1 as an additional regressor. Year fixed effects are included in all regressions.

We use two measures for CEO compensation structure. The first is Bergstresser and Philippon’s (2006) incentive ratio, which is the ratio of the increase in value of CEO stock and options for a 1% increase in stock price to the sum of the increase in the value of CEO stock and options and annual salary and bonus. The second is the percentage of total CEO annual compensation comprised of grants of new stock options, with the options valued using the Black-Scholes formula (Mehran, 1995). Stock return is the buy-and-hold return of the stock in year t. CEO is Chair is an indicator variable that equals one if the CEO is also the chairman of the board and zero otherwise. Tenure is the number of years that the CEO has held the position with the firm. CEO age is the CEO’s age. The dependent variables are measured in year t+1, while the independent variables are measured in year t. See Table 1 for the definition of other variables. Year fixed effects and industry fixed effects are included in all regressions. Numbers in parentheses are t-statistics based on robust standard errors clustered at the industry level.

The dependent variable is an indicator variable for CEO turnover that equals one if the CEO for the firm in year t+1 is not the same as in year t. Geographically concentrated is an indicator variable that equals one if the geographic distance among institutions is in the bottom quartile and zero otherwise. Correlated portfolio is an indicator variable that equals one if the portfolio correlation among institutions is in the top quartile and zero otherwise. Stock return is the buy-and-hold return of the stock in year t. CEO is Chair is an indicator variable that equals one if the CEO is also the chairman of the board and zero otherwise. Tenure is the number of years that the CEO has held the position with the firm. CEO age > 60 is an indicator variable that equals one if the CEO’s age is greater than 60 and zero otherwise. The dependent variables are measured in year t+1, while the independent variables are measured in year t. See Table 1 for the definition of other variables. Numbers in parentheses are t-statistics based on robust standard errors clustered at the industry level. Significance on a 10% (*), 5% (**), or 1% level (***) is indicated.
