On the Relationship between International Outsourcing and Price–Cost Margins in European Industries

This paper sets up a model, where multinationals compete in quantities and domestic firms form a competitive fringe. Within this framework, we analyse the relationship between market concentration, international outsourcing and the industry price-cost margin. The empirical results of a panel of 66 industries and the EU12 countries in the 1990s strongly confirm our theoretical hypotheses. Market concentration and international outsourcing are positively related to industry price–cost margins. In a thought experiment, we show that industry price–cost margins would have decreased by 0.4 percentage points more in the 1990s, if international outsourcing had not changed since 1990. In addition, international outsourcing accounts for a convergence in margins across industries in the last decade.     

Firm Density and Industry R & D Intensity: Theory and Evidence

By deriving a formal model of industry R & D that identifies factors influencing industry R & D intensity, this paper first suggests firm density, defined as the inverse of average firm sales or simply the number of firms divided by industry sales, as a measure of market structure that is appropriate in explaining industry R & D intensity. The model shows that the cost structure of R & D, consumer preference over quality and price, the appropriability of R & D, firm density, and the average level of firm R & D intensity jointly determine industry R & D intensity. In particular, firm density has a positive relationship with industry R & D intensity, implying that firms in higher firm-density industries feel fiercer competitive pressure and thus engage more intensively in R & D. An empirical analysis of panel data on industry R & D activities of Korean manufacturing industries during the period 1991–1996 provides supportive evidence for the predictions of the model including the positive relationship between firm density and industry R & D intensity. The theoretical model and the empirical results are also consistent with the recent survey of U.S. corporate R & D activities by the U.S. Department of Commerce and the National Science Foundation (1999).     

Labor market power and the distorting effects of international trade

This article examines how final product trade with China shapes and interacts with labor market imperfections that create market power in labor markets and prevent an efficient market outcome. I develop a framework for measuring such labor market power distortions in monetary terms and document large degrees of these distortions in Germany's manufacturing sector. Import competition only exerts labor market disciplining effects if firms, rather than employees, possess labor market power. Otherwise, increasing export demand and import competition both fortify existing distortions, which decreases labor market efficiency. This widens the gap between potential and realized output and thus diminishes classical gains from trade.     

邮电通信业市场势力测度及对行业发展影响的实证分析

测度市场势力是监控垄断行业滥用市场势力和反垄断的前提,价格—边际成本差额(即勒纳指数)测度法是广泛认可的市场势力测度方法,但由于边际成本的不可获得性,实际上难以直接应用。本文以广受关注的邮电通信业为例解决了这一难题:基于行业数据特征,通过适当变换替代了经济学难以度量的边际成本和实物量,得到了一种能直接计算勒纳指数的方法,该方法适合于观察中长期市场势力,计量分析中明显优于使用价格—平均成本替代价格—边际成本的功效。基于测度结果,实证了市场势力、技术进步(考虑动态效率)、市场结构变化对行业发展的影响。研究发现,技术进步对行业增长有大的贡献,但市场势力产生了负效应,电信业市场结构调整没有达到业务分拆的初衷。上述研究方法和结论对政府制定垄断行业价格成本监审办法和反垄断立法有借鉴意义。     

A new methodology linking concentration dynamics to current and steady-state profits:Examining Korean industrial policy during take-off

We model the dynamics of industrial structure and market power using Korean manufacturing data during the take-off period (1978–82). Structure–Conduct–Performance [SCP] methodologies have been criticized for using accounting data and because a few superior firms may have greater shares and greater profits. Both are argued to present possible spurious correlations between concentration and profits. This paper follows earlier work which shows that market structure responds to observed accounting profits as if these were accurate indices of real profits, and not as if leading firms are perceived to have unmatchable advantages. The methodological contribution of this model is a new latent variable for steady-state profits derived from the speed of structural adjustment. Long run profits are identified by the hypothesis that structural adjustment will be more rapid when industries are farther from steady-state levels. We analyze the long run profits latent variable, finding strong support for this hypothesis. The speed of adjustment is greater for positive and negative deviations from steady-state structure. We show that the profits and structural adjustment relationship is non-monotone. The SCP criticisms above are based on spurious correlations which are monotone in profits and structure. Positing spurious correlations which are at the same time monotone in structure and non-monotone in structural adjustment seems less plausible than accepting the SCP results which are consistent with both. Our analysis also is new in that it is the first direct econometric analysis of Korean industrial policy during its take-off years. We note that in Korea, unlike elsewhere, Industrial Policy was hypothesized to lead to concentration and market power in the popular press and by professional economists. Ours is the first direct econometric analysis of this hypothesis, and we find it supported.     

Power and firm profitability in supply chains: french manufacturing industry in 1993

The paper examines the relationships between the power of suppliers and buyers and the profitability of sellers who are situated in supply chains between both sets of firms. A review of the literature on power in exchange relations shows there are several power concepts which may have a different impact on seller profitability and whose impact possibly can offset each other. This may be the source of the conflicting evidence on this topic. A failure to distinguish among the concepts may also lead to an underestimation of industry effects relative to resource effects as drivers of firm profitability. The paper uses a new data base of the Banque de France on French manufacturing industry. The anlayses examine whether different power concepts may be empirically identified and what their relationships are with seller profitability. The findings point to the existence of multiple power concepts and indicate that, in the sample, industry effects are more important than firm effects (as measured by relative market share) in explaining seller profitability. The findings also suggest that buyer power explains a much larger percentage of the variance in seller profitability than supplier power. © 1998 John Wiley & Sons, Ltd.     

Testing the Competitive Environment and the Persistence of Profits Hypotheses

In the present paper I examine Brozen's (1970, 1971a, b, c, 1982) Competitive Environment Hypothesis and Mueller's (1977) Persistence of Profits Hypothesis in the Greek manufacturing industries between 1958 and 1984. The analysis reveals a positive (market power) association between past and current price-cost margins, although a considerable scrambling in the ranks of price-cost margins takes place over time. A high concentration and high barriers to entry sub-sample of markets examined, showed a general reduction in concentration, barriers to entry and a mobility in price-cost margins ranks, indicating that disciplinary competitive forces are also at work within manufacturing markets.     

Does the ‘persistence of profits’ persist?: a study of company profits in Japan, 1964–97

Earlier, in a time-series study of the profit rates of Japanese manufacturing firms, Odagiri and Yamawaki concluded that profits persist. With the addition of 15 more years of data up to 1997, this conclusion is shown to stand the test of time. In particular, those firms estimated to earn higher-than-average long-run profit rates in the early study were again estimated to earn higher-than-average long-run profit rates. The force of convergence was also found to be at work; for instance, the firms most profitable in Period 1 (1964–82) were most likely to face a decline in estimated long-run profit rates from Period 1 to Period 2 (1983–97). With the use of two sets of data, the firm’s profit performance was found to be positively related to measures of market share. First, among a smaller sample of firms for which reliable market share data could be matched, market share was estimated to have a significant positive effect on long-run profit rate in either period. Secondly, among the entire sample of 357 firms, the long-run profit rate in either period was estimated to be positively associated with firm sales relative to industry sales, which presumably is a crude measure of market share.     

Performance of acquirers of divested assets: Evidence from the U.S. software industry

We provide a comparative analysis of acquirer returns in acquisitions of public firms, private firms, and divested assets. On the basis of a sample of 5,079 acquisitions by U.S. software industry companies during 1988–2008, we find that acquisitions of divested assets outperform acquisitions of privately held firms, which in turn outperform acquisitions of publicly held firms. While the higher returns for acquisitions of divested assets relative to stand‐alone acquisition targets can be explained by market efficiency arguments, seller distress and improved asset fit further enhance the positive returns of acquirers of divested assets consistent with the relative bargaining power explanation. Finally, we find that the effects of these buyer bargaining advantages are mutually strengthening and that they also hold for longer‐term acquirer performance Copyright © 2013 John Wiley & Sons, Ltd.     

企业对员工的人力资本投资研究

本文利用最新的调查数据研究了企业提供的培训与员工个人特征、企业特征和员工企业匹配特征之间的关系，以及企业培训实践对工资水平的决定效应。研究发现，企业提供的培训投资呈现了极不平衡的现象：技能水平和职位等级高的员工能获得大量的培训投资，处于企业生产和技术部门的一般员工获得的培训投资显著偏低；国有企业大量投资于员工的一般培训，不注重企业专用培训，而外资企业则刚好相反；技术资本密集或者技术进步较快的企业比传统劳动密集型企业更注重员工培训。研究还发现，企业向员工提供的大部分一般培训显著地影响了员工的工资水平。研究结果有助于理解国有企业员工在劳动力市场中的工作转换模式。     

Market Power, Scale Economies and Productivity: Estimates from a Panel of Establishment Data

This paper presents a new econometric framework that permits simultaneous estimation of price-cost margins, scale economies and productivity from a panel of establishment data. The model contains only a few, economically interesting parameters to be estimated, but it is nevertheless consistent with a flexible (translog) underlying technology, quasi-fixed capital and the presence of persistent differences in productivity between establishments. The framework is applied to study market power, scale economies and productivity differences in a number of manufacturing industries in Norway. The results reveal statistically significant, but quite small, margins between price and marginal costs in most manufacturing industries.     

Identifying Participants in a Price-fixing Conspiracy: Output & Market Share Tests Reexamined

If there is a cartel agreement among a subset of firms in an industry, it should be predicted that all firms in that industry will increase prices. Nevertheless, industry prices alone should not indicate that a particular firm is guilty of that conspiracy. According to the output test and its market share variant – proposed by Blair and Romano – if the output or the market share of the firm that claims to be innocent in the collusive activity rises in response to the price increase, that firm's claim should be accepted as true. Using a collusive variant of the dominant firm model, this paper shows that these are not robust tests to reveal either innocence or guilt, and characterizes cases where they may pardon a guilty firm (Type I error) or indict an innocent firm (Type II error). This paper also shows that a market share test can not be used to prove a dominant firm's intent for predatory pricing.     

Imports as Product and Labour Market Discipline

This article tests the pro‐competitive effect of trade in the product and labour markets of UK manufacturing sectors between 1988 and 2003 using a two‐stage estimation procedure. In the first stage, we use data on 11,799 firms from 20 manufacturing sectors to simultaneously estimate mark‐up and workers' bargaining power parameters according to sector, firm size and period. We find a significant drop in both the mark‐up and the workers' bargaining power in the mid‐1990s. In the second stage, we relate our parameters of interest to trade variables. Our results show that imports from developed countries have significantly contributed to the decrease in both mark‐ups and workers' bargaining power.     

Multinationality and downside risk: The roles of option portfolio and organization

Multinational operations confer firms a portfolio of switching options that offer potential operating flexibility in the context of input cost variability, helping firms reduce downside risk. We suggest that two conditions may shape the relationship between multinationality and downside risk. When subadditivity is present in a firm's option portfolio, such as when the firm operates affiliates in host countries with similar labor cost developments, multinationality is less likely to reduce downside risk since less valuable opportunities exist for shifting operations. Multinationality is more likely to reduce downside risk if a firm's organization facilitates the coordination of cross‐border activities, enabling the exploitation of the shifting opportunities. Analysis of a comprehensive panel dataset of Japanese manufacturing firms and their foreign manufacturing affiliates provides support for these conjectures.

制造业外资进入与市场势力波动:竞争还是垄断

对外资市场效应的评估和计量是处理好外资政策、产业政策和反垄断政策关系的重要问题。本文采用中国1999—2010年28个两位数和447个四位数代码制造业面板数据,首先估计了两位数代码制造业的市场势力水平,然后进一步考察外资进入的市场效应,并测度外资引致的福利变动。研究表明:制造业各行业存在显著的市场势力,但金融危机前后市场势力溢价水平波动较大。全样本结果显示制造业市场势力溢价约为6.2%,但金融危机前样本证实市场势力溢价高达22.1%。细分产业中,外资的竞争效应占主导,但在部分产业中外资表现出了反竞争效应。制造业总体层面上,外资进入与市场势力波动之间呈现U形非线性关系,拐点稳定在外资比重为47.3%—54.0%的区间内。从福利角度看,外资进入的竞争效应,使得垄断带来的无谓损失减少了3334.70亿元;但FDI的反竞争效应使得相应行业垄断福利损失增加2407.45亿元。     

Market Share Instability and the Dynamics of Competition: a Panel Data Analysis of Japanese Manufacturing Industries

This paper explores market share instability as a measure of market mobility. Using a newly constructed panel data set, we examine the determinants of the market share instability of leading firms in Japanese manufacturing industries. The findings suggest that there is a significant relationship between concentration and market share instability, and the market shares of leading firms are more stable in highly concentrated industries. We also provide evidence that industry growth has a significantly positive effect on market share instability.     

The Determinants of Survival of Spanish Manufacturing Firms

This paper analyses the factors determining Spanish manufacturing firms survival–and exit. The data are drawn from the survey Encuesta sobre Estrategias Empresariales for the period 1990–1999. The methodology includes both non-parametric techniques and the estimation of a Cox proportional hazards model (CPHM). Our results suggest that the probability of exit is higher for small firms and also for young and mature firms. Furthermore, exporting firms and firms performing R&D activities enjoy better survival prospects.     

Advertising, Its Determinants, and Market Structure

This study derives a formal model of firm advertising behavior and applies it to the industry level to figure out the relationship between advertising and market structure. The firm advertising model shows that both consumer preference andfirm-specific advertising competence jointly determineprofit-maximizing advertising intensity. At the industry level, advertising intensity is represented multiplicatively by consumer preference and a measure of market structure, which reflects the joint distribution of the levels of advertising competence and market shares among firms. The new market structure measure suggests that those single-dimensional measures of market structure such as seller concentration and the Herfindahl index are inadequate in explaining interindustry differences in advertising intensity, and that the long-debated advertising-concentration relationship differs depending primarily on the appropriability of advertising. An empirical analysis of 426 five-digit Korean manufacturing industries shows that an inverted U-shaped relationship between the Herfindahl index and industry advertising intensity is observed for consumer goods industries but a lazy J-shaped relationship for producer goods industries.     

Market Power,Efficiency and the Dispersion of Systematic Risk

A number of studies have used the Capital Asset Pricing Model (CAPM) to integrate product market and financial theories of the firm. We reexamine the relationship between product market structure and systematic risk at the firm and industry level. We show that theory yields no testable implications at the firm level. We show, however, that there is a relationship between the intraindustry dispersion of systematic risk and industry concentration which depends on the causes and consequences of concentration. Estimates of the relationship between the intraindustry variance of and concentration for a 1987 cross-section of U.S. industries suggest that concentration allows larger firms to exercise market power.     

Diversification, Concentration and Economic Performance: Korean Business Groups

The purpose of this paper is to analyze empirically some of therelationships involving corporate diversification, concentration and economic performance for agroup of 25 of the largest Korean chaebols or business groups over the period 1985–1995. UsingHerfindahl–Hirschman indices of inter-industry diversification and intra-group member firm concentration,our results indicate that increased conglomerate diversification does not affect chaebol profitswhereas changes in internal member firm concentration do. Of particular interest with respect to bothdiversification and concentration are our findings that a quadratic relationship exists between groupprofits and the number of member firms, with both smaller and larger chaebols having higher profitsthan intermediate size chaebols. A similar relationship also exists with respect to group size measuredin terms of total assets. Since the number of member firms is included as an explanatory variable, ourresults imply that profitable chaebols expand primarily within their existing industries ratherthan by adding firms in new markets.
