Mark-ups can provide valuable information on competitive pressures in various sectors of the economy, reflecting pressures stemming from rules of conduct imposed by regulators as well as those arising from such factors as increasing consumer demands in terms of price and quality. Trade and FDI are also sources of such pressure. In particular, FDI can be important is very often it is the only source of competitive pressure. Although mark-ups are only an imperfect measure of competition, the information they provide on market conditions can be useful for inferring trade restrictiveness as they can at a later stage be decomposed into the major sources driving mark-ups in various sectors. Developments in the theoretical and empirical literature over the past decades suggest a departure from the standard assumptions of neoclassical production theory with respect to perfect competition and constant returns to scale. This departure allows for the assumption of monopolistic firms charging markups over marginal costs and opens up new avenues for the estimation of such mark-ups. Following Roeger (1995), the difference between the primal and the dual Solow residuals is explained as a result of imperfect competition and by subtracting the two residuals from each other, the unobservable productivity term cancels out. This way, the price-cost margins can be estimated consistently by standard econometric techniques, though the results obtained are mark-ups over average cost and not marginal cost. The assumption of constant returns to scale may, however, be too restrictive as not all sectors in all countries may exhibit constant returns to scale. Following Dobrinsky et al. (2004), this assumption is relaxed and mark-ups are re-estimated for the sectors and countries for which the hypothesis of constant returns to scale was rejected. The novelty of this paper is that it (i) allows for non-constant returns to scale when estimating markups for a number of OECD countries, (ii) jointly estimates mark-ups for all sectors and in all countries, (iii) estimates mark-ups for services sectors at a conveniently detailed level of disaggregation and (iv) uses different estimates of input coefficients of the production function that feed into the estimation function of mark-ups to check for robustness of results. The estimation is done for the period 1993-2006 and is confined to European Members of the OECD because the underlying database for the analysis (Amadeus) only covers Europe. In general, the estimated mark-ups are higher for professional services, real estate, renting and utilities, while they tended to be substantially lower for construction, computer services, retail and wholesale trade and catering. From the limited number of estimates for the telecommunications sector it can be inferred that mark-ups in this sector are somewhere in between these two ends of the spectrum. There is also large variation across countries in terms of the sizes of the estimated mark-ups. Competitive pressures according to these mark-ups should be large in the United Kingdom and most Scandinavian countries, and relatively small in Central European countries, Sweden and Italy. Spain, Germany and France are in between these two groups. Corresponding author, Senior Economist, Trade and Agriculture Directorate, OECD. T: +33 1 4524 8949.

The methodology applied could also be further refined, for example, by using the Levinsohn-Petrin method to obtain the input coefficients of the production function. With such improvements, these mark-up estimates could better serve as inputs for use in a top-down approach to assessment of service trade restrictiveness. Also, in future analysis, competitive pressures stemming from regulation could be delineated from other pressures stemming from other sources using the newly estimated mark-ups. 5 Introduction One way to infer the relative restrictiveness of economic regulation in different markets is to compare competitive pressures prevailing in those markets. Mark-ups can provide valuable information on competitive pressures in various sectors of the economy, reflecting pressures stemming from rules of conduct imposed by regulators as well as those arising from such factors as increasing consumer demands in terms of price and quality. Trade and FDI are also sources of such pressure. In particular, FDI can be important is very often it is the only source of competitive pressure. Although mark-ups are only an imperfect measure of competition, the information they provide on market conditions can be useful for inferring trade restrictiveness as they can at a later stage be decomposed into the major sources driving mark-ups in various sectors. Mark-ups have some analytical advantages over approaches to assessment of competitive pressures that rely on concentration indices such as the Herfindahl-Hirsch Index. These indices may be misleading in that higher market shares are not necessarily associated with lower competitive pressure; by the same token, in fragmented markets with numerous small players there is not necessarily higher competitive pressure. Mark-ups, in turn, assess the effect of a number of sources of competitive pressure that may not be related to market structures. Mark-up estimation belongs to the top-down approaches for assessment of services trade restrictiveness. The mark-up approach provides information on the overall competitive pressure in a market, but does not allow for the identification of particular regulatory measures that drive these competitive pressures. Therefore, it may be appropriate to use mark-ups in combination with regulatory indices to get a fuller picture of the impact of regulation on services trade. In lack of available recent estimates of mark-ups in services industries for OECD countries, this paper proposes new estimates based on micro-data. This allows for aggregation at a detailed level so that estimates for, for instance, different professional services can be obtained separately. An estimation at a disaggregated level also allows for testing (i) whether mark-ups are higher in services where customerspecific products prevail and markets are segmented such as legal services, (ii) whether mark-ups are lower in services that are more traded such as computer services or business consultancy (iii) whether mark-ups are higher in services that require more human capital input such as engineering and (iv) whether mark-ups are higher in network industries owing to the large sunk and fixed costs these industries have to assume. The paper is structured as follows: after setting the scene by highlighting the need to estimate markups using firm-level data, the estimation method is described along with the data used; then, the estimates are compared across countries and sectors and finally their relationship with regulatory indicators is examined. A summary of the findings and possible further steps conclude the paper. New estimates using firm-level data There is an abundant literature on estimating mark-ups, but most studies are constrained to a particular country and to manufacturing industries. Very few studies cover several countries, let alone focus on OECD countries and include services industries. The study by Høj et al. (2007) is one of the few exceptions, estimating mark-ups using industry-level data for 19 OECD countries1 over 1975-2002. The coverage of services in that study, however, is limited to just 6 industries2 and it does not include 1. Austria, Belgium, Canada, Germany, Denmark, Spain, Finland, France, UK, Italy, Japan, Korea, Luxembourg, Netherlands, Norway, Sweden and the United States. 2. Electricity, gas and water supply; wholesale and retail trade, repairs; transport and storage; post and telecommunications, financial intermediation and business services. 6 construction. In addition, the authors lump telecommunications with posts and provide only a single estimate for all business services.3 The use of firm-level data in the analysis that follows allows for aggregation of sectors depending on the purpose of analysis and also for the exploitation of information in a manner that is not possible in the case of industry-level data. Also, using firm level data avoids measurement problems related to input and output measures at the sectoral level. At the same time, there are also drawbacks to using firm-level data, in particular the limited length of available time series. Also, due to constraints in the data drawn from the Amadeus database (the main data source for the present study), mark-ups can only be estimated for countries and sectors where there are a sufficient number of firms. In addition, dealing with micro-data implies much higher work intensity in the estimation of mark-ups and constrains the choices of estimation methods and software used. How are the estimates obtained? Developments in the theoretical and empirical literature over the past decades suggest a departure from the standard assumptions of the neoclassical production theory in terms of perfect competition and constant returns to scale. This departure allows for the assumption of monopolistic firms charging markups over marginal costs and opens up new avenues for the estimation of such mark-ups. Here the Roeger (1995) method is applied, which has recently been widely used owing to its simplicity. Roeger (1995) explains the difference between the primal and the dual Solow residuals as a result of imperfect competition and his method has the beauty of simplicity relative to the method pioneered by Hall (1988), overcoming the need to use variables in volumes and to apply instrumental variables technique. Roeger (1995) also exploits the cancelling out of the unobservable productivity term (present in both residuals) when subtracting the two Solow residuals from each other. This way, the price-cost margins can be estimated consistently by standard econometric techniques. A drawback of this method is that the results obtained this way are mark-ups over average cost and not marginal cost. The production technology is assumed to be defined by the neoclassical production function: (1) where Y is output, A is multifactor productivity growth, there are three inputs: N is labour, M is intermediate inputs and K is capital and F(.) is a homogenous function of degree lambda (the degree of returns to scale). The firm and year subscripts are subtracted for the sake of simplicity. After logdifferentiation4 and re-arranging: (2) where is the primal Solow residual, the lower case indicates log-differentiation, revenue share of factor i and B is the Lerner index, which is closely related to the mark-up µ: is the 3. Due to the limited availability of data, Høj et al. (2007) only estimate mark-ups for all the 6 services sectors for 8 countries: Austria, Germany, Denmark, Finland, France, Netherlands, Norway and the United States. No services mark-ups are available from the study for Spain and the number of services sectors for which markups are estimated varies between 1 and 5 for the remaining countries. Owing to insufficient length of time series, mark-ups are not estimated for any Central European country. 4. Through differentiation, the growth rate of output can be related to the growth rates of inputs, i.e. capital, labour and materials. 7 (3) The dual, or priced-based Solow residual is derived by using the cost-function associated with the production function in equation (1). (4) where w is the growth rate of wages, is of material prices, r is of the rental price of capital and p is of output. By subtracting (4) from (2) and adding an error term, B can be estimated as Roeger (1995) showed. As the unobservable productivity term, a cancels out with this subtraction, this equation is relatively easy to estimate. Oliveira Martins et al. (1996) show that the equation to estimate the mark-up can also be derived from the direct definition of the mark-up over average cost: (5) where AC is average cost, P, W, and R are the prices of output, labour, intermediate inputs and capital, respectively, whereas λ is an index of returns to scale (i.e. average costs over marginal costs) and µ is the mark-up. After differentiation and under the assumption of constant returns to scale (λ=1) the equation to estimate (after adding an error term) is obtained: (6) where the first term in the left-hand side is nominal output, the second is wage cost multiplied by the estimated coefficient on labour from the production function, the third is material costs multiplied by the estimated coefficient on material inputs and the fourth is the rental price of capital multiplied by the estimated coefficient on capital (1- ), all in differences. The totality of the left-hand side is the Solow residual with variables measured in nominal terms. In the right hand-side, B is the Lerner index ((Price-Average Cost)/Price) to estimate, which can be used to compute the mark-ups according to: Data Most of the data are obtained from a subset of the Amadeus database comprising nearly 1.5 million European companies.5 The subset was obtained by including any company that meets one of the following criteria, depending on the reporting country: A. France, Germany, Italy and the United Kingdom (i) operating revenue equal to at least EUR 1.5 million, (ii) total assets equal to at least EUR 3 million, or 5. Unlike the case of sectoral data, adjustment for differences in tax systems across countries is not necessary as no taxes affect only one side of either inputs or outputs. 8 (iii) the number of employees equals at least 20. B. Austria, Belgium, Czech Republic, Denmark, Finland, Greece, Hungary, Iceland, Ireland, Netherlands, Norway, Poland, Portugal, Slovak Republic, Spain, Sweden and Switzerland (i) operating revenue equal to at least EUR 1 million, (ii) total assets equal to at least EUR 2 million or (iii) the number of employees equals at least 20. The dataset contains firms’ balance sheets and profit and loss accounts and information on stocks, shareholders, subsidiaries and activities. Company-specific nominal data needed for the estimation of the production function and the markups are directly obtained from the Amadeus database. For the output variable, operating revenue or sales is used; for labour the number of employees is used and for capital, fixed assets. For material – in most countries – the variable called “material costs” is used, but for Denmark, Greece, Iceland, Ireland, Netherlands and the UK, cost of goods sold is used. For wages, there is a straightforward variable to use, except in the case of Greece, where due to the lack of the wage expenditure variable (or company-specific information on the wage rate), mark-ups were estimated using the industry-specific wage expenditure from the STAN database. The rental price of capital is calculated from the following equation: (7) where i is the long term interest rate, is expected inflation and is the depreciation ratio and pk is the fixed asset investment deflator. For the calculation of the rental price of capital, the yield on benchmark government 10 year bonds (or similar maturity) are used from the OECD Economic Outlook database;6 expected inflation is proxied by the Hodrick-Prescott-filtered GDP deflator, which is also extracted from the OECD Economic Outlook database. The depreciation ratio is country-specific and is calculated from the depreciation costs available in the Amadeus database. For the fixed-asset investment deflator sectorspecific deflators are used with the exception of Greece, Iceland, Poland, Portugal, Sweden, Switzerland and the United Kingdom, where, in lack of such data, the economy-wide deflator for business investment from the OECD Economic Outlook database is applied. The Amadeus database classifies firms into 4-digit and 2-digit NACE categories. Due to the limited number of companies in several countries at the 4-digit level and to a slightly different selection of sectors of interest for the present study, the industries were reclassified into a mix of 2- and 4-digit NACE categories, avoiding overlap. This way, mark-ups were estimated for 29 services sectors, including electricity, gas, steam and hot water supply, collection, purification and distribution of water, construction, car sale and gasoline retail, wholesale trade, retail trade, hotels and restaurants, land transport, water transport, air transport, other transport activities, post, telecommunications, financial intermediation,7 activities related to financial intermediation, real estate, renting of machinery and equipment, computer and 6. For Hungary, data for the yield on benchmark government 10-year bonds were obtained from the National Bank of Hungary and for Greece from Eurostat. In lack of such data for the Czech Republic and Poland, long-term lending rates are used. 7. Except insurance and pension funds which are missing from the database. 9 related activities, research and development, legal services, accounting services, advertising services, engineering and architecture services, education and other community, social and personal services. Given the coverage of the Amadeus database with 21 countries and the selection of 29 services sectors, ideally there should be 609 mark-up estimates. In reality, however, given the limited number of observations for some countries and several sectors, the number of estimated mark-ups is substantially lower. Choices of estimation and specification techniques Mark-ups are estimated using two alternative techniques that differ at the first step of estimating the production function; factor shares were determined by: (i) using an ordinary least squares (OLS) method with fixed effects or (ii) computing the shares. The OLS fixed-effects method assumes that productivity that influences firms’ choice is a time-invariant firm-specific attribute and corrects for it by including firm fixed effects.8 The second method relies on computation of the factor shares instead of econometric estimation. The OLS fixed effects method can produce country and sector estimates, while computed factor shares are obtained at the firm level. The application of the two methods allows for the exploitation of the richness of information related to heterogeneity at the country, sector and firm level (and across time). The second step, which is the estimation of the Lerner indices, is identical in the two cases. The Lerner indices were estimated by OLS with and without fixed effects, year dummies and time trend. The Lerner indices were jointly estimated for all countries and all sectors in the sample. The mark-ups were then retrieved from equation (3) and the corresponding standard errors were computed by the delta method. Both estimation methods were applied for two specifications: (i) assuming constant returns to scale and (ii) relaxing the constraint of constant returns to scale. The validity of the assumption of constant returns is checked by econometric tests. Where constant returns were rejected, this constraint was relaxed and the mark-up was estimated under non-constant returns. From the assumption of common input coefficients to sector- and country-specific ones The easiest way to estimate the mark-ups would be to assume that the production functions are identical across countries and industries. A simple F-test, however, shows that even for the 21 European countries covered by the database we cannot assume that firms in the same sector behave the same way across countries. By the same token, firms in the same countries but in different sectors exhibit different characteristics. Therefore, country- and industry-specific input coefficients are estimated simultaneously to be used as inputs for the second step where mark-ups are derived. The second approach, where the factor shares are computed and not estimated, implies firm-specific shares, i.e. the input coefficients are computed at the firm level. Relaxing the assumption of constant returns to scale Constant returns to scale may not hold for all industries, therefore its validity needs to be tested. The hypothesis of constant returns to scale was rejected for several groups; therefore the mark-ups were reestimated under the relaxation of the assumption of constant returns. Following Dobrinsky et al. (2004), to estimate the mark-ups under non-constant returns to scale, the returns to scale index, λ was estimated, and the new mark-up computed from the Lerner index obtained in the case of constant returns to scale: 8. Resources permitting, superior techniques such as the Levinsohn-Petrin method could also be employed to estimate the input coefficients of the production function. 10 (8) How large are the estimates and how do they compare across countries and sectors? The estimated mark-ups confirm large heterogeneity across sectors and countries. This is not surprising given that sector-specific characteristics affect the mark-ups companies can charge over average costs and that the forces driving competition – and hence reducing mark-ups – vary across sectors and countries. These differences may, to a considerable extent, be related to different domestic regulatory regimes. Notwithstanding this heterogeneity in the estimated mark-ups, some general trends can be identified. With regards to the pilot sectors (i.e. those covered in the current phase of the OECD services trade restrictiveness work), in general, mark-ups are high in professional services, lower in telecom services and lowest in the construction industry and computer services. Not surprisingly, in professional services, such as legal or consultancy services, where human capital is a major input, where most products are customerspecific and where information asymmetry is a major issue, mark-ups are higher than in most other services industries. Some of these services, such as legal services, are less tradable than other professional services, implying even higher mark-ups. Network industries, in general, exhibit higher mark-ups than inherently competitive non-network services such as retail trading or construction. Among network services, mark-ups in telecommunications are relatively lower, probably implying higher competitive pressures in telecommunications markets and increasingly demanding customers with respect to services quality and prices. When looking also at other sectors, mark-ups appear high in financial services, real estate and renting, while trade-related activities (sale of motor vehicles, wholesale and retail trade) are among sectors with the lowest mark-ups. Transport-related sectors are placed between these two extremes. Real estate and renting are characterised by high level of asymmetric information between suppliers and customers giving rise to pricing powers by suppliers. Across countries, the Central European members appear to experience the highest mark-ups alongside Italy, Portugal and Sweden. At the other end, the United Kingdom and some Scandinavian countries seem to have the lowest mark-ups. The large continental countries of France and Germany as well as Spain are in-between these two groups. The following sector-specific discussion of some of the findings will give some insights into the differences in mark-ups across sectors and countries. Estimates obtained by both methods (i.e. with input coefficients estimated by fixed-effect OLS and computed input shares) are presented to show the robustness of results. The relative sizes of the estimates somewhat differ, with the computed method having an upward bias. While the estimated-coefficient method is economically more solid, many observations are lost owing to the estimation procedure. Therefore, where the purpose is to compare as many countries/sectors as possible, the computed-coefficient method may be more useful. Competitive pressure in computer services implies small mark-ups in most countries The computer services market is unregulated in the countries in the sample and computer services are generally tradable. As expected under such circumstances, the analysis points to relatively low mark-ups in most countries (Figure 1). Exceptions are the Central European countries, and to a lesser extent Italy, Sweden and Austria. Most computer services sectors are characterised by non-constant returns to scale except in Finland, where the constant returns to scale hypothesis was not rejected. 11 Figure 8.

Source: Authors’ estimation. Mark-ups in the construction sector are relatively low in general with elevated levels in some countries Generally, the construction sector also appears to exhibit relatively low mark-ups (Figure 2). This wedge is very small in Denmark, relatively small in the UK, Spain, Hungary, Finland, Belgium, Norway and Greece, but relatively high for other Central European countries, Sweden, Portugal and Italy. Given the large number of players in the sector in most countries, mark-ups in construction were obtained using the fixed-effect method for the estimation of the input coefficients for as many as 15 countries. With the computed input coefficients, the number of estimates is even larger (18), though this method tends to overestimate mark-ups. The sector exhibits non-constant returns to scale in all countries in the sample. 12 Figure 9. Mark-ups in the construction sector are relatively low Panel A.

Source: Authors’ estimation. Mark-ups are high in professional services In general, mark-ups are high in professional services sectors in most countries. In architectural and engineering services, Finland, Greece, Norway, Spain and the UK appear to have relatively high competitive pressure and therefore low mark-ups (Figure 3). Most other countries have high mark-ups in this sub-sector, e.g. Italy, Poland, Sweden or the Czech Republic. In accounting, the number of countries where data availability allowed for the estimation of mark-ups is fewer (given the small number of large and large number of small players in this market and the limited sample to medium- to large-size firms). In countries for which mark-ups were estimated, they are generally high with the exception of Finland, France, Greece, Iceland, Norway and Poland. Given the small size of legal services firms, in general and the exclusion of such firms from the sample, the mark-ups in this sector could only be estimated for a handful of countries. Finland and Greece again appear to charge smaller mark-ups over average costs, while in most other countries for which it could be estimated, the mark-ups are relatively high, e.g. in Italy, Norway, Poland and Sweden. 13 Figure 10.

Source: Authors’ estimation. Professional services are inherently competitive services and the exceptionally high mark-ups in this sector may indicate inadequate competitive pressure. Unnecessary regulation and the lack of recognition of qualifications may give a particular boost to firms’ pricing power in this sector. Comparing the newly obtained mark-ups with previous OECD estimates Comparability with previous OECD estimates is limited, but the relative magnitudes of mark-ups across countries are mostly similar. Oliveira Martins et al. (1996) provided the first comprehensive markups for OECD countries, though their estimation of mark-ups was limited to manufacturing industries. As noted above, Høj et al. (2007) extended the coverage to include up to 6 services industries (depending on the country) and estimated the mark-ups for 19 countries over 1975-2002. In trade, where owing to the large number of observations, mark-ups were estimated for a number of countries, the new estimates are comparable to the ones obtained in Høj et al. (2007) especially when taking into consideration the different time periods (1993-2006 and 1975-2002) for which the mark-ups were estimated (Figure 4). 14 Figure 11.

While mark-ups reflect competitive pressures in markets, such competitive pressures can partly stem from conduct rules imposed by regulatory bodies, but also from other sources such as increasingly demanding consumers, international trade or foreign direct investment in the country. The proper delineation of sources of competitive pressure remains a topic for future work, but preliminarily, simple charts can already provide some indication of the relationship between mark-ups and regulations. In construction services, those countries with the highest mark-ups such as Poland, Slovak Republic, Sweden and the Czech Republic also have restrictive foreign direct investment (FDI) policies (Figure 5). However, Finland’s score on restrictiveness towards inward FDI is even more restrictive but it has low mark-ups in the construction sector. FDI, of course, is not the only source of competitive pressure and even in the absence of foreign investors, there may develop a competitive domestic market. Nevertheless, the positive association between FDI restrictiveness and mark-ups indicate that foreign competitors may indeed constitute an important source of competitive pressure. In some countries with strict restriction on FDI, mark-ups are higher in construction services, 2006 .12 Figure 12. Finland .08 Slovak Rep Poland Sweden .06 Norway .02 .04 FDI restr .1 Czech Rep.

In the countries where mark-ups are high in telecommunications services, restrictiveness towards inward FDI in the sector also tends to be high (Figure 6). Iceland is a case in point, but also other countries, such as France and Sweden, fit this description. Figure 13.

Professional services, for instance architectural and engineering services, are not an exception to the observed positive association between the size of mark-ups and the restrictiveness of regulations. Higher regulation in architectural and engineering services including entry, qualification requirements and regulations related to conduct, are associated with higher mark-ups in the sector (Figure 7).

Mark-ups are estimated for 1993-2006. Source: OECD FDI restrictiveness indices and authors’ estimation. 16 What have we learnt and what else could be done? Mark-ups provide a comparative perspective on competitive pressures in markets in different countries and industries. In general, the estimated mark-ups were higher for professional services, real estate, renting and utilities, while they tended to be substantially lower for construction, computer services, retail and wholesale trade and catering. From the limited number of estimates for the telecommunications sector it can be inferred that mark-ups in this sector are somewhere in between these two ends of the spectrum. There is also large variation across countries in terms of the sizes of the estimated mark-ups. Competitive pressures according to these mark-ups should be large in the United Kingdom and most Scandinavian countries, and relatively small in Central European countries, Sweden and Italy. Spain, Germany and France are in between these two groups. To allow for comparison across a larger number of OECD countries, the analyses could be extended to non-European Members using the Orbis database. The methodology applied could also be further refined, for example, by using the Levinsohn-Petrin method to obtain the input coefficients of the production function. With such improvements, these mark-up estimates could better serve as inputs for use in a top-down approach to assessment of service trade restrictiveness. Also, in future analyses, competitive pressures stemming from regulation could be delineated from other pressures stemming from other sources using the newly estimated mark-ups. 17 REFERENCES Dobrinsky, R., G.
