How Does Data-Driven Decision-Making Affect Firm Productivity and CEO Pay? Erik Brynjolfsson, MIT Sloan Lorin Hitt, Wharton, School, University of Pennsylvania Heekyung Kim, MIT Sloan September 15, 2010 Preliminary and Incomplete Draft For consideration at WISE 2010 Comments welcome. Please do not quote. Abstract While there is a great deal of anecdotal evidence that firms can boost their performance by adopting a data driven decision-making (DDD) approach, there is little data or systematic analysis of these claims themselves. We gather detailed information on the business practices and information technology investments of 165 large publicly traded firms and find that DDD can explain a 3-5% increase in their output and productivity, beyond what can be explained by traditional inputs and IT usage. Furthermore, firms with more DDD tend to have a higher degree of consistency in business practices across business units and geography and stronger linkages between business and technology. In addition, we find that DDD is correlated with a significant increase in CEO pay even after controlling for the average worker’s wage, suggesting that the data-driven decision-making may further widen the gap between top managers and average workers. Intriguingly, the quadratic effect of DDD is positive for CEO compensation, but not for firm productivity, echoing Rosen’s (1982) model of increasing rewards to “superstars”. 1. Introduction Each revolution in science is typically preceded by a revolution in measurement and data gathering. The invention of microscope, for example, allowed the exploration of an entire new world that had been invisible, transforming biology and medicine. Today’s data revolution promises to transform management in an equally fundamental way. Businesses now can measure consumer behavior, business operations and myriad other aspects of their environment with unprecedented precision. For instance, clickstream data provides an unprecedented digital trace of customer actions and ERP systems generate terabytes of data as byproducts of their normal activities, while email, RFID, mobile phones, and many other information technologies are all contributing to a doubling of the quantity of business data roughly every 1.2 years. Data by itself does not change anything. It must be analyzed and used to change decisions to have any value. The ability to collect and analyze the enormous amount of data is, therefore, becoming of critical importance for firms to stay competitive and gain market share. Ironically, although there is a great deal of anecdotal evidence of firms’ using data to gain a competitive edge in the business press in popular books, there has been virtually no systematic data analysis of the productivity effects of data-driven decision making using statistical methods. We seek to address this gap by examining detailed business practices and information technology investment of publicly traded large 165 firms in the US. We find that approximately 3-5% increase in the productivity can be explained by data-driven decision-making (DDD) and that the top executives in data driven firms, particular CEOs, have reaped disproportionately large rewards in terms of personal compensation. Our results can help explain not only the relatively higher productivity growth rates that IT-intensive firms have recently experienced, but also the growing gap between CEO pay and the compensation of ordinary workers. As information technology has penetrated every step of business practices, business decisions are increasingly relying on data and experiments. Consumer-facing companies rich in transaction data are routinely testing innovations and randomized testing is standard procedure in online firms such as Amazon, eBay, and Google. For example, Amazon.com continually experiments with their websites for the best appearance. “We have been implementing changes on <online site> based on opinion, gut feeling or perceived belief. It was clear that this was no way to run a successful business…Now we can release modifications to the page based on purely on statistical data” (Kohavi, Longbotham et al., 2009). Kohavi et al. (2009) illustrates how data can overrule the traditional approach of relying on intuition and “the highest paid person’s opinion” (HiPPO) for corporate decision-making. “Greg Linden at Amazon created a prototype to show personalized recommendations based on items in the shopping cart. Linden notes that while the prototype looked promising, a marketing senior vice-president was dead set against it, claiming it will distract people from checking out. Greg was forbidden to work on this any further. Nonetheless, Greg ran a controlled experiment” to prove that the new feature would bring in a lot more sales at a statistically significant level and the HiPPO was wrong. This suggests that information technology, once thought of a major driver in widening income gap between college and high school graduates by replacing workers of routine and simple clerical jobs (i.e., Autor, Katz et al., 1998) is now poised to replace HiPPOs. On the contrary, however, we have been witnessing that a further widening income gap in every sector and every income percentile of the population in recent years (i.e., Piketty and Saez, 2003). In this study we report that the data-driven decision-making is correlated with the increase in CEO’s pay even after controlling for the average worker’s wage, suggesting that DDD is further widening the income gap between the top manager and other workers. Our interpretation of this finding is that information technology is eroding the high-level managers’ work as it has replaced the workers of routine jobs (Autor, Katz et al., 1998), shrunken the ranks of middle managers (Pinsonneault and Kraemer, 1997), and flattened hierarchies (Rajan and Wulf, 2006). At the same time, however, it is complementing the CEO’s job. A CEO’s vision for the future and steering her firm to the future cannot be experimented and replaced by data. Rather, talented CEOs are even more in demand to make sound decisions based on the ever-increasing amount of information, to shape her firm to be data-driven and encourage her employees to experiment and collect and analyze data, to exploit the capability of information technology to gain a competitive advantage. 2. Theory The starting point for economic theories of the value of information typically begins with the seminal work of Blackwell (1953). Blackwell’s theorem (Blackwell, 1953) states that decision makers observe signals correlated to the state of nature prior to their choice of action and hence “update” the probability distribution before the “optimal” action is chosen. In this framework the value of information (in terms of expected utility) is always positive. Since the advent of computers in the 1980s, firms have deployed enormous resources to computerize work and collect information. Many researchers, however, showed that only organizations with certain characteristics such as high endowments of human capital and decentralized work practices tend to reap the benefit of their information technology investment (i.e., Bresnahan, Brynjolfsson et al., 2002). Our study is related to the stream of literature, uncovering another organizational characteristic that may be associated with this increase in productivity. Controlling for firms’ human capital and information technology investments, we show that data-driven decisionmaking practices (DDD) significantly affect firm productivity, and are also highly correlated with the consistency of business practices across business units. The increase in the amount of available information may not be always valuable when acquiring and processing the information is too costly. “The real issue is not the lack of data, but our ability to properly process and distribute the information quickly. If we cannot properly process and distribute the information quickly, we run the risk of destroying the value of the information we are striving so hard to attain.” (Collins, 2010). CIOs have expressed concerns that after investing in data collection, they lack the capability and personnel to analyze these data.1 Our study explores the question by empirically examining whether there is an optimal level of DDD. While the answer to the question is inconclusive due to our limited sample size, a striking result emerged – the reward to CEOs shows increasing returns to investments in DDD. For instance, we find that firms at two standard deviations above the mean of our DDD scale have CEO compensation four times larger than the average firm. CEO compensation might be related to DDD because it affects the ability of organizations to transfer and process knowledge. In particular, information technology makes some types of information alienable from workers or mid-level managers (see e.g. Brynjolfsson, 1993) but not necessarily the most senior managers. This increases the marginal value of decisions made by CEOs. 1 CIO forum, MIT center for digital business, 2010. Numerous researchers have noted that some information is not easily transferable because it “tacit” (i.e., Polanyi, 1958; Rosenberg, 1982) or “specific” (i.e., Jensen and Meckling, 1976) or “sticky”(i.e., Von Hippel, 1994). Advancement in information technology has, however, brought in a wave of codification of knowledge. Balconi, 2002) presented an illustrative example of the changes in the progressive codification of technological knowledge occurred over the last 30 years formerly embodied in skilled workers in the steel industry. Until the end of the 1960s instruments to measure the temperature and chemical composition of liquid steel were not widely available so measurements were carried out based on some physical characteristics observable by sight. For example, “in order to know the temperature of liquid steel, a sample was taken out of the furnace, poured upon an iron plate and the temperature was deduced by observing the forming of the spot, its shape and the way it solidified and attached itself to the plate.” The ability to recognize the temperature by sight was acquired with 5 years of experience or more. By the 1970s the content and the temperature of liquid steel was routinely conducted by automated measurement tools but the process was still controlled by workers and line managers. By the end of 1980s the whole processing cycle was automated. Since the mid-90s, workers are principally involved in monitoring automated data collection and processing equipment, and approving process changes recommended by the processing algorithms. Over time, the knowledge once embodied in experienced workers has been supplanted by machine monitoring and largely automated decision making. A consequence is that the specialized knowledge only possessed by the most skilled individuals can now be embedded in computer instruments and available to distant operators in the operating rooms throughout the entire company. More broadly, firms now gather and propogate knowledge not only from production workers, but from their consumers, suppliers, alliance partners, and competitors much faster and more cheaply with the aid of information technology, make information available for distant decision makers. Knowledge generation does not stop at passive analysis of data. New and broadly available software has enabled managers to conduct active experiments with their new business ideas and base their decisions on scientifically valid data. From banks such as PNC, Toronto-Dominion, and Wells Fargo to retailers such as CKE Restaurants, Famous Footwear, Food Lion, Sears, and Subway to online firms such as Amazon, eBay, and Google, firms test many business ideas through a randomized test before launch, called as “information-based strategy” (Davenport, 2009). This information-based strategy alienates the high-level manager’s tacit knowledge – the knowledge of what was or was not likely to be a successful business innovation. Just as the process of controlling steel processes was transformed by improved measurement of temperature, the innovative process in an online business is now being transformed by the improved measurement of customer preferences. However, this process automation cannot substitute for strategic decision making, although it does allow strategic decisions to be moved from managers at the level of a task or a business unit, to a manager with responsibility for the entire firm. Consequently, a small difference in the talent of top manager who has an enormous amount of information to process may make a huge difference to the fortune of the firm. Our study is also related to the effects of IT on command, control, coordination, and organization of firms (see Leavitt and Whisler, 1958;Rule and Attewell, 1989;Gurbaxani and Whang, 1991;Malone, Yates et al., 1987;Brynjolfsson and Mendelson, 1993;Brynjolfsson, Malone et al., 1994;Brynjolfsson and Hitt, 2000 and the literature reviews cited therein). In theory, IT could shift power either toward the center or away from it, leading to centralization or decentralization of a firm. If IT can transfer knowledge to central managers, a firm can become more centralized which would suggest higher CEO relative pay. On the other hand, if IT facilitates lateral communication of local knowledge between employees, employees can coordinate tasks among themselves more easily with the need for senior management involvement, suggesting lower CEO relative pay. Researchers have found evidence of decentralization at task level, but the increase in the scope of CEO as well (Rajan and Wulf, 2006). Our finding is consistent with the increase in the scope of CEO, but not as a substitute for decentralized work practices. Data driven firms generally invest in both decentralized work practices, but with greater overall centralized coordination of these activities, making them consistent across the firm. Our study is also related to the literature on IT and wage inequality (i.e., Autor, Katz et al., 1998). Our view on the role of IT in increasing CEO pay is close to those of Garicano (Garicano and Rossi-Hansberg, 2006;Garicano, 2000). Their model suggests a hierarchy of knowledge. Some knowledge resides in lower level employees and is used to solve routine problems, while other knowledge resides in higher-level employees that is primary directed at solving non-routine problems. As the cost of communication among agents decreases, the complicated problems that lower-ranked employees cannot solve can be easily passed to their superiors. Once solved, the solution can be disseminated throughout the firm and become part of routine work practice. This can lead to the dependency of the problem-solving on a few “superstars” (Rosen, 1981) and thus a higher wage for the superstars. Their explanation is consistent with our view that the availability of data allows a distant few problem solvers to provide a solution to non-trivial problems and increase their marginal productivity disproportionately. Therefore, data driven firms become dependent on a small number of superstars which should be associated with greater pay. CEOs may or may not be one of these problem solvers, but they are nonetheless responsible for coordinating, managing, and rewarding their activities, which also increases the marginal value of their effort. Finally, our study is related to the literature on CEO compensation, especially studies that document or explain the observed increase in CEO pay. Following Gabaix and Landier’s (2008) summary of the literature on the topic, we recapitulate the literature in four views. The agency view (Jensen and Murphy, 1990;Dow and Raposo, 2005;Holmstrom and Kaplan, 2001) suggests that increased expected compensation is necessary to provide incentives in an increasingly volatile business environment and to reward difficult to measure activities like innovation. The market failure view (Yermack, 1997;Bertrand and Mullainathan, 2001;Bebchuk and Fried, 2005;Bebchuk, Fried et al., 2002;Hall and Murphy, 2003) suggests that the rise in CEO pay is a consequence of failure of corporate governance mechanisms. A third possibility is that the CEO job has changed (Frydman, 2005) to become more general which has increased their outside options and put upward pressure on pay. Finally, the market equilibrium view (Gabaix and Landier, 2008;Tervio, 2008) suggests that CEO pay increases simply reflect an increase in firms size. In equilibrium, the most talented CEO is correctly matched to the largest firm and paid the highest because the marginal value of their decisions is greatest there. Our paper is most closely linked to the market equilibrium view; the increased marginal productivity of CEOs resulted from the increase of firm size is a major determinant of the recent rise of CEO pay. We articulate that what is relevant to the marginal productivity of CEO is an effective size, of which data-driven firm is greater than others of the same nominal size. The more data-driven a firm is, the easier the flow and access of knowledge and thus the larger the effective size of the firm that distant managers can control. As a result, the marginal productivity of CEO increases and this drives an increase in CEO pay. Our argument is related to the study by Baker and Hall (Baker and Hall, 2004), who attributed to a specific mechanism of increased marginal productivity. In particular, they argue that when CEOs perform tasks that affect the entire firm, optimal compensation should be connected to the proportional change in value rather than the absolute change in value. As firms become larger, this implies larger CEO pay. Since modern investments in DDD tend to lead to firm wide changes or standardization of processes across the firm, the Baker and Hall argument would suggest that DDD leads to greater CEO compensation. One challenge to investigating these theories is that different firms, in different vary in the marginal productivity and therefore wages of all workers (Katz and Summers, 1989;Krueger and Summers, 1987;Krueger and Summers, 1988;Gibbons and Katz, 1992). For example, the median workers’ wage in the industry of computer systems and related services, $65,000, was over 3-times higher than that in the industry of food services, $18,000, in 2005. This variance is at least partly due to the fact that DDD can raise the productivity of all workers. However, our theory predicts not just increases in wages, but disproportionate increases in the wages of top executives. Therefore, to isolate this effect, we will control for wages of other workers in our analysis. Data Our business practice and information system measures are estimated from a survey administered to senior human resource (HR) managers and chief information officers (CIO) from large publicly traded firms in 2008. We received matched responses (both HR and CIO) from 127 firms, HR only responses from 122 firms, and only CIOs-only responses from 81 firms. The survey asks over 80 questions on business practices as well as organization and usage of information systems. The questions extend a previous wave of surveys on IT usage and workplace organization administered in 1995-1996 and 2001 (Hitt and Brynjolfsson, 1997 Tambe, Hitt et al., ), but adds additional questions on organizational structure, the usage of information for decision making, and the consistency of their organizational practices. To test our hypothesis, we used the survey response to construct measures of firms’ organizational practices. We combine these measures with publicly financial data and CEO compensation. This yielded 164 firms with complete data for an analysis of firm productivity, and 165 firms during the same period with the variables needed to analyze CEO compensation. Our sample spans manufacturing, retail/wholesale trade, information, and finance/insurance industries over the period from 2005 to 2009. Business Practices We constructed our key independent variable, data-driven decision-making (DDD), from three questions of the survey: 1) the usage of data for the creation of a new product or service, 2) the usage of data for business decision-making in the entire company, and 3) the existence of data for decision-making in the entire company. Two other measures from the survey were also constructed to indicate the general employee’s human capital; 1) the importance of typical employee’s education and 2) the average of % of employees using e-mail and % of employees using PCs, workstation, or terminal. capture in 5-point Likert scales. All measures except the ones based on percentages were We created DDD by first standardizing each factor with mean of zero and standard deviation of 1 and then standardizing the sum of each factor for each composite measure: DDD = STD(STD(use of data for creation of a new product/service) + STD(use of data for business decision in the entire company) + STD(existence of data for such a decision)) To examine the factors which may be correlated with DDD, we constructed a number of other organizational measures listed in Table 1. “Consistency” refers to the consistency of business practices in the entire company. The consistency measure was constructed from a composite of responses to six survey questions on consistency of business practices across operating units, within business units, across functions, and across geographies (4 questions); the effectiveness of IT for supporting consistent practices; and consistency of prioritization of projects (Table 1). “BT-link” captures the integration of business strategy with information technology and is derived from size survey questions focusing on the interaction of employees from both groups, understanding of each other, and the importance of technology in strategy. “Dissemination” was based on two questions focusing on embedding processes in technology and the ability of the firm to disseminate business practices across the firm.. “IT-governance” is a measure on how IT project is governed in terms of prioritization, involvement with business, and managing demand and benefit. “Find” is the effectiveness of employees’ finding knowledge or a colleague with a particular expertise or broadcasting their expertise. “Exploration” is the capability of innovating and creating a new business capability, product or service, a composite from 7 survey questions. “Exploitation” is the ability of improving their existing capability, a composite from 15 survey questions. The number of instances of IT systems on ERP/SCM, CRM, HR, and Financial Systems and the level of centralization of IT resources on application development and maintenance was used to construct a composite designated “Centralized IT system”. We capture employee human capital a question about the importance of typical employee’s education and the percentage of employees using emails or pc were included. Financial data Financial measures were derived from Compustat. Measures of physical assets, employees, sales and operating income were taken directly from the Industrial annual file from 2005 to 2009. Materials were estimated by subtracting operating income before tax and labor expense from sales. In the case that labor expense was not available, the industry-average was used with the industry average based on average labor expense for all firms that report labor expense and employees in the same industry at the most detailed industry breakdown available. CEO compensation We used Compustat database for Executive pay for the period from 2005 to 2009 which provides data on compensation of as many as 13 senior executives from each company. The Executives database is compiled from proxy statements filed by the companies in compliance with Securities and Exchange Commission (SEC). The two measures of CEO compensation were used; one is the variable, tdc1, from Compustat Executives data set and the other is the sum of salary and bonus. The tdc1 includes salary, bonus, other annual, restricted stock grants, LITP payouts, all other, and value of option grants valued at the day of grants. For a variable for firm’s nominal size, we used three variables; total employee number, sales, or market capitalization. Market capitalization was estimated in the same way as Gabaix and Landier (2008) as the market value of equity at the end of the fiscal year, plus debt less deferred taxes. IT-employee data The survey included the questions about IT budgets, outsourcing, change of IT budgets from 2008 to 2009, and full time IT employment. The number of full-time IT employees for the year 2008 was asked in the survey, but for the year 2009 it was estimated from the questions on IT budget. Using the change of IT budget from 2008 to 2009, the percentage of outsourcing, and IT FTE for 2008, we were able to estimate the IT FTE for the year 2009. The year from 2005 and 2006, we used data collected in a previous study (Tambe and Hitt, ). For the year 2007, a moving average from 2005, 2006, 2008 and 2009 was used. The number of non-IT employees is equal to the number of employees reported on Compustat less our computed IT employment measure. 3. Methods Productivity Tests We use the Cobb-Douglas specification, the most commonly used model in information technology and productivity literature (e.g., Brynjolfsson and Hitt, 1993, 1996; Dewan and Min, 1997). Our primary regression model can be written as the following: ln ()ݏ݈݁ܽݏ௧ = ߚ + ߚଵ ln(݇)୧୲ + ߚଶ ln( ܶܫ− )݁݁ݕ݈݉ܧ୧୲ + ߚଷ ln(ܰ ݊− )݁݁ݕ݈݉ܧ ܶܫ୧୲ + ߚସ (DDD)୧୲ + ߚହ (DDDxDDD)୧୲ Where k is physical capital, IT-Employee is the number of IT employees, Non-IT Employee is the number of Non-IT employees, DDD is our data-driven decision-making variable, and DDDxDDD is the square term of DDD. The last term, DDDxDDD, was included to examine the potential for increasing marginal productivity effects of DDD. In some specifications, we included variables indicating the firm’s human capital, such as importance of typical employee’s education, to rule out some alternative explanations for our results. Although our data on IT and other production inputs and outputs are longitudinal, our main independent variable, DDD, is based on a single survey conducted in 2008. We constructed a 5year panel (2005-2009) by making the assumption that DDD was the same for the years from 2005 to 2009. Similar assumptions have been used in previous studies (Bresnahan, Brynjolfsson et al., 2002), and many researchers have reported that organizational practices change very slowly, especially for large firms (i.e., Milgrom and Roberts, 1990 Hannan and Freeman, 1984). For a robustness check, we categorized the firms into 5 groups based on their response to one of the survey questions about the change in the consistency of their business practices. The productivity tests were conducted controlling for the group, examining the effect of DDD within the same group which is likely to have a similar degree of change in the consistency of business practices. The rationale for this test was based on the observation that the consistency of business practices was highly correlated with DDD in our sample firms. Therefore, the change in the consistency of business practices is likely to be correlated with the change in DDD. Estimating the effect of DDD within the same group mitigates the bias that our assumption may cause. CEO Compensation Tests A robust and high correlation between the nominal size of a firm and its CEO compensation has been supported by theoretical and empirical models in numerous studies (i.e., Baker and Hall, 2004; Gabaix and Landier, 2008) . We extend the model in prior literature by including our organizational variable, DDD and the square term of DDD to capture nonlinear effects. Our empirical model specification is therefore: ln(ܿ݁௧ ) = ߚଵ + ߚଶ ln(݂݅)݁ݖ݅ݏ ݉ݎ୧୲ + ߚଷ (DDD) + ߚସ (DDDxDDD) where ceoit is CEO pay of firm i and year t. We used output as the firm size in most analysis but results are similar when other measures of size are used (employees, assets and market capitalization). In some specifications, we include other variables to control for firm’s human capital to address other potential omitted variables explaining the result. 4. Results and Discussion Productivity Tests The key result for the productivity was shown in Table 2; the first column is the productivity test only with capital, employee, and materials. The coefficients associated with IT employee and non-IT employee are consistent with previous studies (i.e., Tambe, Hitt et al., ). The second column shows the model including our key independent variable, DDD. These coefficients suggest that firms with a one standard deviation higher in on our measure of data-driven decision making (DDD) have a 5% greater productivity than the mean firm. In the third column we add the square of DDD. We find it to be negative but not significant, suggesting the possibility of declining marginal benefits. Our results are largely unchanged when we include a variety of human capital controls. In table 3, we examine the relationship between our DDD measure and other organizational practices. One surprising result was that individual IT use (employees using PCs or e-mail) was not correlated with DDD at all. It seems that the widespread usage of computers and e-mail do not separate high IT-usage firms from low-IT usage firms by this measure. The consistency of business practices across business units was positively correlated with the output in some industries at a statistically significant level (results not shown). The complementarity between DDD and the consistency measure was not, however, statistically significant (results not shown). We assumed that DDD was the same for the tested period (2005-2009). To check the robustness of this assumption, we categorized our sample firms in 5 groups based on their answers on the change of the consistency of business practices over the last 3 years because the change of the consistency of business practices is likely to be correlated with the change of DDD. The DDD coefficient was qualitatively the same for both models; one controlling for the group, the other not controlling for the group (Table 4). Overall, our results are consistent with a positive relationship between DDD and productivity that is robust to a variety of controls and checks. CEO Compensation and DDD Table 5 reports our analysis of the relationship between CEO pay and firm size. The first 3 columns use the total compensation as the dependent variable including options and the next 3 models only the sum of salary and bonus. This result is robust to using physical capital as a size control, which leads to small change reduction in the DDD coefficient. When market capitalization was used as firm size variable, the coefficient of DDD is reduced by half. By construction, the market capitalization value includes the stock price and reflects the expected value of future sales. Firms with high DDD are likely to have a potential to grow faster and their stock price may reflect the growth potential . Indeed, DDD is correlated with the market capitalization at a statistically significant level. When the growth potential of a firm is captured through its market capitalization, DDD coefficient may become smaller. Following the norm in the literature of CEO compensation where sales are most commonly used as size variable, we selected sales as size variable in the next model specifications (Table 6). In the models in Table 6 the nonlinearity of CEO pay on DDD was first examined. Although the coefficient of the square term of DDD in the first model in Table 4 is not statistically significant at 90% confidence level, it becomes statistically significant when more controls are included. It is a striking result that CEO pay increases not only with DDD but the square term of DDD. This result echoes Rosen’s result (1981) that top talent’s earing increases with the quadratic term of her talent as both price and the size of market increases with her talent. Further study will formulate a model to link our result to Rosen’s economics of superstars (1981). DDD coefficient was still statistically significant after controllling for firms’ human capital measured in the importance of education and percentage of employees. Conclusion Overall, a variety of literature suggests a potential connection between data driven decision making, productivity and executive compensation. Using survey data, our initial analysis suggests that DDD is associated with productivity. Moreover, we find a positive and increasing effect of DDD on executive compensation, consistent with the idea that DDD increases the value of central decision makers and “superstar” individual decision makers. More analysis will be conducted to strengthen this result by considering more complex models that control for firm heterogeneity and potential reverse causality. Table 1.

Firms were categorized into 5 groups based on their response to a question on the change in the consistency of business practices. The question was “To what extent do the following statements describe the work practices and environment of your entire company; our business processes have become more consistent over the past 3 years.” The choices were from 1 as “Describes not all” to 5 to “Completely describes”. The first column is a model controlling for the group and the second not controlling for the group.
