walrasian equilibria as limits of noncooperative equilibria part i mixed strategies abstract we examine the connection between walrasian equilibria of a limit economy with infinitesimal firms and the noncooperative cournot equilibria of approximating finite economies with significant firms following earlier work of novshek and sonnenschein we allow for set up cost and permit a minimal form of mixed strategies we depart from them by requiring that the aggregate production set exhibits some degree however small of decreasing returns contrasting with their results it is shown that a regular walrasian equilibrium of a limit economy can always be approximated by a sequence of noncooperative equilibria for the tail of the approximating finite economies thus there is a surprising qualitative discontinuity when one passes from the novshek sonnenschein case of aggregate constant returns to scale of the decreasing returns case of this paper

union coverage and profitability among u s firms this paper utilizes unique survey data on labor union coverage at the firm level to examine union effects on the profitability of 705 u s companies during the 1970s market value and earnings are estimated to be about 10 15 percent lower in an average unionized company than in a nonunion company following extensive control for firm and industry characteristics deleterious union effects on firm profitability are sizable throughout the 1972 80 period but vary considerably across industries the relatively poor profit performance of unionized companies may help explain the recent decline in u s union membership the author thanks the w e upjohn institute for employment research for financial support elizabeth gregory for assistance with the union coverage survey zvi griliches for providing access to the rd donald deere terry seaks and anonymous referees for helpful suggestions and seminar participants at connecticut florida state harvard texas a m and william and mary for comments on earlier versions of this research

the impact on economic performance of a transformation in workplace relations this study examines how a transformation in patterns of conflict and cooperation affected economic performance in 25 work areas of a large unionized manufacturing facility in the period 1984 87 unlike most studies of industrial relations and economic performance this study clearly distinguishes conflict from cooperation but evaluates the two together rather than focusing on only one an analysis of data collected from union and employer records and interviews strongly suggests that work areas with traditional labor management relations rooted in adversarial assumptions had higher costs more scrap lower productivity and a lower return to direct labor hours worked than work areas with transformational relations characterized by increased cooperation and improved dispute resolution

approximate efficiency of cournot equilibria in large markets this paper establishes necessary and sufficient conditions for the approximate efficiency of cournot equilibria in large markets the analysis is carried out in the partial equilibrium framework of a market for a homogeneous commodity

labor unions bargaining power and corporate bond yield spreads structural credit model perspectives abstract this study investigates labor union effects on bond yield spreads from perspectives of structural credit models by employing american bond observations from 2001 to 2007 this research finds that union strength significantly and positively relates to bond yield spreads this effect is roughly equal to that of issuer rating for one standard deviation change when controlling for well known variables the empirical results also show that the positive effects become weaker when management has higher bargaining power additionally union strength volatility significantly and negatively relates to bond yield spreads and capital structure leverage the above results are robust when controlling for credit ratings collinearity concerns industry effect and tax effect

on the dominance solvability of large cournot games we consider cournot s model of oligopolistic competition in a market for a homogeneous good we seek conditions under which the oligopolists game is dominance solvable and hence the cournot equilibrium is the only outcome that survives iterated deletion of dominated strategies we focus on large oligopolies whereby we define an oligopoly to be large if both the demand and the supply side are replicated more than a certain finite number of times we show that large cournot oligopolies are dominance solvable if and only if the equilibrium of the approximated perfectly competitive market is globally stable under cobweb dynamics journal of economic literature classification numbers 022 1995 academic press inc

centralized bargaining and reorganized work are they compatible the paper examines the implications for wage bargaining of an important aspect of the ongoing reorganization of work the move from occupational specialization toward multi tasking the analysis shows how on account of such reorganization centralized bargaining becomes increasingly ine cient and detrimental to rms pro t opportunities since it prevents rms from o ering their employees adequate incentives to perform the appropriate mix of tasks the paper also shows how centralized bargaining inhibits rms from using wages to induce workers to learn how to use their experience from one set of tasks to enhance their performance at other tasks in this way the paper may also help explain the increasing resistance to centralized bargaining in various advanced market economies 2001 elsevier science b v all rights reserved

exploring technology diffusion in emerging markets the role of public policy for wind energy abstract this study challenges the implicit assumption of homogeneity in national institutional contexts made in past studies of renewable energy policy we propose that institutional differences matter by focusing on several technology specific and generic policy factors that can foster technology diffusion through private sector activity more specifically we explore perceptions of early adopters in emerging economy contexts using wind park project developers as an example by applying a parsimonious method for our questionnaire as well as qualitative data we make several contributions methodologically we introduce maximum difference scaling to the energy policy domain empirically we identify several public influences on private investment and assess their relative importance this leads to new insights challenging findings from industrialized economies we identified additional institutional barriers to diffusion hence the requirement of a combination of technology specific and generic policy measures

industrial relations performance economic performance and qwl programs an interplant analysis this study analyzes the relationship among plant level measures of industrial relations performance economic performance and quality of working life programs the analysis employs pooled time series and cross section data from 18 plants within a division of general motors for the years 1970 79 the empirical results show strong associations between industrial relations and economic performance measures and limited support for the hypothesis that quality of working life efforts improve both kinds of performance

equal employment opportunity law and firm profitability based on a sample of 260 cases reported in the wall street journal between 1964 and 1986 this study finds that the equity value of firms charged with violating equal employment opportunity eeo laws fell at the time that a suit decision or settlement was announced most dramatically the value of firms involved in class action suits fell 15 6 percent on average around the time of the suit further the average loss to shareholders exceeds the amount firms are required to spend to settle the case this may be due to the expected costs of changing employment practices or to the information about the firm s management that is revealed by the case a staggering number of statutes amendments and court decisions regulating equal opportunity in employment have been passed during the past 25 years firms found guilty of violations of equal employment opportunity laws have been required to pay millions of dollars in back pay and to alter their employment practices to comply with the laws this study measures the costs to firms resulting from government and private lawsuits and the further costs of losing those suits i address this question by examining changes in the market value of the equity of firms at the time a lawsuit is filed for a violation of an equal employment opportunity eeo law and at the time a decision of guilty or a settlement

initiating a sustained diffusion of wind power the role of public private partnerships in spain the literature on policy approaches for the market support of renewable electricity is dominated by narrow conceptualizations of policy referring mostly to direct instruments for economic feasibility such approaches often led to unsatisfactory explanations of diffusion results this is the case of wind power diffusion in spain the success of which is typically credited to the feed in tariff instrument this paper offers an alternative explanatory account for wind power diffusion in spain it is argued that diffusion can be explained by a less obvious policy of stimulating investments by means of public private partnerships ppps the three legal frameworks for economic feasibility applicable up to 2004 harbored high economic risks although projects could have high profitability because of generous investment subsidies up to mid 1990s most investments were based on ppps to address the risk perceptions of early investors fully private partnerships now dominate investments though ppps have not disappeared next to winning investors confidence the ppp policy led to an investment culture whereby partnership investments dominate by 2000 95 7 of the installed wind capacity was owned by partnerships and only 4 3 by individual companies partnerships invest in larger projects have ambitious investment plans and these lead to a high diffusion tempo

renewable energy sources in the spanish electricity market instruments and effects the implementation of directive 2001 77 ec on the promotion of electricity produced from renewable sources sets a target of 22 1 of electricity consumption in the eu in 2010 and establishes various mechanisms that member countries may adopt depending on their needs this paper analyses these mechanisms their implementation in spain by means of rd 661 2007 and the degree of fulfilment of objectives it concludes with an analysis of the effectiveness of the mechanisms adopted and recommendations on market design

the effect of two tier collective bargaining agreements on shareholder equity this study uses an event time methodology to examine the impact of two tier agreements on shareholder equity from 1981 through 1986 following announcements of two tier agreements about half of the firms in the sample had negative abnormal returns returns with values below the expected market returns and half had positive abnormal returns because the positive returns exceeded the negative returns in absolute value however there was a statistically significant increase in mean firm value the abnormal returns averaged between 2 and 4 over a 10 to 12 week period following the announcement a figure that approximately equals the transactions cost of a stock purchase the authors speculate that this rather low average gain may help explain the marked decline of new two tier agreements during the latter half of the 1980s

employment protection and takeovers labor restructuring is a key driver of takeovers and the associated synergy gains worldwide in a difference in differences research design we show that major increases in employment protection reduce takeover activity by 14 27 and the combined firm gains synergies by over half consistent with the labor channel behind these effects deals with greater potential for workforce restructuring show a greater reduction in volume number and synergies the reforms do impede layoffs and the associated wage costs match the magnitude of synergy losses offer prices are not fully adjusted with both bidders and targets exhibiting lower returns following the reforms

cournot equilibrium in large markets under increasing returns abstract we consider cournot partial equilibria in large markets where firms have decreasing average costs it is shown that the outcome of competition is approximatelyefficient if entry is free

the effects of the nlra on stockholder wealth in the 1930s whereas most recent research examining the effects of the nlra on labor management relations has focused on the impact of specific provisions of the law this study provides an estimate of the impact of the passage of the nlra on 75 firms that were at great risk of being unionized in the 1930s taking changes in shareholder wealth as a measure of the shift in the balance of power caused by the nlra the authors find that the passage of the nlra caused a statistically and economically significant decline in shareholder wealth for the sampled firms specifically by april 1937 stockholder wealth in the firms was 15 9 lower than would have been expected had the nlra not been enacted t he impact of public policy on the balance of power between labor and management has always been a fundamental topic in industrial relations recent changes in many labor management relationships have renewed interest in the influence of public policy on labor relations and raised questions of how modifications in these policies might alter the behavior of the parties according to delaney lewin and sockell 1985 the empirical research on this topic has largely concentrated on specific provisions of the wagner act such as election procedures and regulation of employer unfair labor practices for example getman gold

the union impact on profits evidence from industry price cost margin data this paper uses industry price cost margin data to estimate the extent to which unions reduce profits estimates allowing for the endogeneity of union status are contrasted with estimates that assume union status is exogenous and not determined in part by either profitability or industry structure endogeneity is found to be an important consideration in estimating the union impact on profits two stage estimates are considerably larger than ols estimates the final section explores the total estimated redistribution from capital to labor in the manufacturing sector an important conclusion is that unions raise prices less than was previously believed

imitators and optimizers in cournot oligopoly we analyze a symmetric n firm cournot oligopoly with a heterogeneous popu lation of optimizers and imitators imitators mimic the output decision of the most successful firms of the previous round a la vega redondo 1997 optimizers play a myopic best response to the opponents previous output firms are allowed to make mistakes and deviate from the decision rules with a small probability apply ing stochastic stability analysis we find that the long run distribution converges to a recurrent set of states in which imitators are better o than are optimizers this finding appears to be robust even when optimizers are more sophisticated it suggests that imitators drive optimizers out of the market contradicting a funda mental conjecture by friedman 1953

the efficiency of monopolistically competitive equilibria in large economies commodity differentiation with gross substitutes abstract a general model of commodity differentiation is developed using two different approaches to the theory of demand it is shown that a local version of bertrand s argument holds under reasonable conditions if all commodities are sustitutes and sunk costs are small there is never too little commodity differentiation relative to the optimum under the same conditions monopolistically competitive equilibria are approximately perfectly competitive if the optimal collection of commodities is sufficiently rich

the impact of labour unions on external auditor selection and audit scope evidence from the korean market abstractwe examine whether labour unions influence external auditor selection and audit scope as a major user group of financial information labour unions likely demand financial information of high quality and thus high quality audits as a union s request for wage increases is likely strong when a firm is performing well management facing wage negotiations with the labour union has incentives to manipulate earnings downward and may therefore prefer auditors who allow more discretion using union data unique to korea during 2005 2008 we find that firms with a stronger labour union tend to choose higher quality auditors i e big n or industry specialist auditors we also find that unionization is negatively positively associated with positive negative abnormal audit fees and audit hours and the effects are more pronounced when the union is stronger and more active given that departures from normal audit fees and audit hours in either direction arguably impair audit quality this finding is con

worker participation and productivity in labor managed and participatory capitalist firms a meta analysis using meta analytic techniques the author synthesizes the results of 43 published studies to investigate the effects on productivity of various forms of worker participation worker participation in decision making mandated codetermination profit sharing worker ownership employee stock ownership or individual worker ownership of the firm s assets and collective ownership of assets workers collective ownership of reserves over which they have no individual claim he finds that codetermination laws are negatively associated with productivity but profit sharing worker ownership and worker participation in decision making are all positively associated with productivity all the observed correlations are stronger among labor managed firms firms owned and controlled by workers than among participatory capitalist firms firms adopting one or more participation schemes involving employees such as esops or quality circles

concession bargaining the impact on shareholders equity this analysis of bargaining settlements in 1982 83 shows that on average shareholders in those firms that negotiated concessionary settlements enjoyed an 8 to 10 percent increase in the value of their holdings the author interprets this result to mean not that the value of the firm increased but rather that concessions enlarged the shareholders portion of the firm s value at the expense of the workers portion on the other hand concession bargaining does not seem to have reallocated business risk between shareholders and labor finally the evidence suggests that firm specific sources of risk can explain in part not only the magnitude of the concession effects but also the probability that concession bargaining will occur

perfectly competitive markets as the limits of cournot markets a perfectly competitive partial equilibrium market for a single homogeneous good with a bounded continuum of infinitesimal firms is considered cost functions are essentially unrestricted and are allowed to vary smoothly across firms a sequence net of cournot markets each with a finite number of firms which converge smoothly to the perfectly competitive limit in terms of both the inverse demand functions and the distributioon of firm technologies is introduced and it is shown that all markets sufficiently far along the sequence have a cournot equilibrium and all the cournot equilibria converge to the perfectly competitive equilibrium of the limit market

the political economy of international green certificate markets this paper analyzes the political economy of establishing bilateral trade in green certificate markets as one step towards harmonization of european green electricity support systems we outline some of the economic principles of an integrated bilateral green certificates market and then discuss a number of issues that are deemed to be critical for the effectiveness stability and legitimacy of such a market by drawing on some of the lessons of the fairly recent intentions to integrate a future green certificate market in norway with the existing swedish one we highlight exemplify and discuss some critical policy implementation and design issues these include for instance the system s connection to climate policy targets the role of other support schemes and the definition of what green electricity technologies should be included furthermore the establishment of an international market presumes that the benefits of renewable power e g its impacts on the environment diversification of the power mix self sufficiency etc are approached and valued from an international perspective rather than from a national one thus implying lesser emphasis on for instance employment and regional development impacts a bilateral green certificate system thus faces a number of important policy challenges but at the same time it could provide important institutional learning effects that can be useful for future attempts aiming at achieving greater policy integration in the european renewable energy sector

impacts of a common green certificate market on electricity and co2 emission markets in the nordic countries abstract the purpose of this study is to analyze the effects of introducing a common nordic system for tradable green certificates tgcs on the electricity market and a future market for tradable co 2 emission permits teps in the analysis the energy system model generator markal was used to model the electricity and district heating supply systems in the four nordic countries sweden norway finland and denmark it is shown that the introduction of tgc quotas reduces wholesale electricity and tep prices the impact on the latter is very pronounced retail electricity prices may become lower or higher depending on the tgc quota than if obligations to fulfill tgc quotas were absent the tgc scheme s efficiency in reducing a specific amount of co 2 emissions is also compared to the corresponding efficiency of a tep scheme involving a broader range of technologies furthermore obligations to fulfill tgc quotas affect investment incentives for new non renewable electricity supply this seems especially true for gas fired power plants finally it is indicated that electricity supply based on biomass combustion dominates the tgc scheme at least in the short run

union firm bargaining and the influence of product market power and production technology on systematic risk the relationship between the capm firm beta and the firm s microeconomic decisions is studied by a model under uncertainty which combines the feature of an ex ante inputs substituable production technology and the existence of a union which bargains over various economic dimensions of the firm it is shown that the earlier findings of a relationship between the firm beta the firm product market power and the labor capital ratio may be reinforced through the indirect channel of labor market bargaining but the relationship becomes more complex and heavily depends on the scope of the union firm bargaining process this yields the empirical prediction confirmed for a panel of belgian firms that any proper estimation of the determinants of firm beta must control for firms in the sample being unionized

employee voice human resource practices and quit rates evidence from the telecommunications industry the authors draw on strategic human resource and industrial relations theories to identify the sets of employee voice mechanisms and human resource practices that are likely to predict firm level quit rates then empirically evaluate the predictive power of these variables using data from a 1998 establishmentlevel survey in the telecommunications industry with respect to alternative voice mechanisms they find that union representation predicts lower quit rates even after they control for compensation and a wide range of other human resource practices that may be affected by collective bargaining also predicting lower quit rates is employee participation in offline problem solving groups and in self directed teams no apparent association is found between quit rates and the availability of nonunion dispute resolution procedures regarding human resource practices higher relative wages and internal promotion policies predict lower quit rates and contingent staffing electronic monitoring and variable pay predict higher rates

taking stock collective bargaining at the turn of the century examining data from two national surveys of matched pairs of union and management lead negotiators the authors evaluate the current state of practice in labor relations and test several propositions related to the transformation of american industrial relations they find that 30 40 of the parties reported that they had introduced negotiated workplace level innovations or engaged in strategic level interactions both important aspects of transformation also nearly half of the parties reported experience with use of interest based bargaining practices at the same time relatively few parties reported relationships that were improving and views on the extent of change differed between labor and management thus there is an identifiable path supporting the transformation process but only a minority of bargaining relationships are moving down that path

unions and cooperative behavior the effect of discounting using union contract and industry wage survey data this article examines the effect of discounting on cooperative bargaining behavior by unions and firms game theory predicts that higher discount rates raise the temptation to defect from cooperation measures of cooperative behavior included the presence of merit pay incentive pay wage employment guarantees or labor management study committees discount rates were proxied by the relevant industry s failure rate failure rates generally had negative effects on cooperation industry wage survey results showed larger effects for union than non union establishments providing support for the union bargaining framework

union rent seeking intangible capital and market value of the firm abstract this study considers the effect of unions on intangi ble capital investment and profitability within the context of a market value rather than a more traditional accounting based approach theory is provided suggesting unions are able to affect profitability by sharing in the economic returns to firm specific intangible capital in support of this hypothesis we find unionization reduces the returns to r d and produces a corresponding limiting influence on r d investment at the firm level i introduction a n extensive literature in economics has ex amined the determinants of profitability with much of the focus centering on the role of market structure only recently however have the effects of labor unions on profitability been analyzed ths is surprising since labor economists long have emphasized union influences on wages and productivity that in turn may affect profitabil ity in recent studies freeman 1983 and karier 1985 report a significant limiting influence of unions on price cost margins in high concentra tion manufacturing industries using firm level data and the market based tobin s

unionization and profitability evidence from the capital market this paper examines the effect of unionization on the profitability of firms abnormal monthly common stock returns for a sample of 253 nyse listed firms are estimated for the month in which the union petitions for an election and for the month in which the national labor relations board certifies the election outcome the results suggest that unionization on average is associated with a reduction in equity value when unions win an election the average loss associated with the unionization drive is 3 8 percent of equity value when unions lose an election there is an average net reduction of 1 3 percent in the equity value of the firm

capital labor and the firm a study of german codetermination under the german corporate governance system of codetermination employees are legally allocated control rights over corporate assets through seats on the supervisory board that is the board of nonexecutive directors the supervisory board oversees the management board the board of executive directors approves or rejects its decisions and appoints its members and sets their salaries we empirically investigate the implications of this sort of labor participation in corporate decision making we find that companies with equal representation of employees and shareholders on the supervisory board trade at a 31 stock market discount as compared with companies where employee representatives fill only one third of the supervisory board seats we show that under equal representation management board compensation provides incentives that are not conducive to furthering shareholders interests possibly because labor maximizes a different objective function than shareholders we document that under equal representation companies have longer payrolls than their one third representation peers have finally we provide evidence that shareholders respond to the allocation of control rights to labor by linking supervisory board compensation to firm performance and by leveraging up the firm jel g32 g34

right to work laws new evidence from the stock market 1 introduction business organizations the national right to work committee and organized labor periodically devote enormous resources to battles over passage or repeal of individual state rightto work rtw laws all rtw laws outlaw union shop agreements clauses in collective bargaining agreements that require employees to join the union that represents them and about half also outlaw agency shop agreements clauses in collective bargaining agreements that require nonmembers to pay a fee to the union to cover the cost of representation supporters of rtw argue that employees should not be required to pay dues to a labor organization that they do not support opponents argue that because union contracts and grievance arbitration systems cover all employees members and nonmembers rtw laws encourage free riding by individuals who want to gain the benefits of unionization without bearing the costs and that this weakens labor unions are rtw laws largely symbolic or do they reduce union membership the probability of union growth and union bargaining power informed opinion is still sharply divided one view is that rtw laws reduce the probability of union organizing at least in the years immediately following their passage and that this along with lower levels of membership in previously organized units reduces the level of unionization in a state e g hirsch 1980 carroll 1983 garofalo and malhotra 1992 davis and huston 1993 1995 ellwood and fine 1987 present evidence that the effect on new organizing is most severe with new organizing diminished between 32 and 38 in the 10 years after passage of a rtw law 1 zax and ichniowski 1991 see also ichniowski and zax 1991 demonstrate that the dampening of new organizing extends to the public sector when it operates under rtw laws even when those laws are favorable to unions in other respects others however argue that rtw legislation is largely symbolic it reflects the prevailing anti union opinion climate of a particular state but has little independent impact on union organizing or membership moore and newman 1985 1975 wessels 1981 lumsden and peterson 1975 sobel 1995 presents evidence on the true number of free riders consistent with the taste hypothesis rtw legislation is passed in this perspective in states in which public opinion is anti union and the labor movement is politically weak in these states workers are less attracted to unions and it is this public opinion climate rather than the law itself that hurts union growth 2 we present a new type of evidence on this issue from two states in which public opinion had turned sharply against unions or at least in favor of rtw in the period before the passage of a rtw law we reason that if passage of the rtw law itself actually lowers the probability of unionization or reduces the bargaining power of unions operating within a particular state beyond the effect of the prior shift in attitudes then anticipated future profits of firms operating in that state will rise in response to passage of that law because unions are associated with lower firm profits 3 hence equity values of those firms will increase we use event study methodology to discover whether or not this actually happened in louisiana when it passed a rtw law in 1976 and in idaho when it passed a rtw law in 1985 1986 4 louisiana and idaho are both well suited to research based on the event study technique legislative action in both states took place in the period in which daily stock price data are available from all three sources of stock price data new york american and nasdaq 5 daily as opposed to monthly stock price data are much more likely to reveal statistically significant changes in shareholder equity brown and warner 1985 because we use daily rather than monthly data a finding of no statistically significant change in shareholder equity would be valid evidence that rtw laws are symbolic rather than substantive

harmonization of renewable electricity feed in laws in the european union this paper focuses on the harmonization of feed in laws in the european union as a support mechanism for the promotion of renewable electricity in particular it proposes a methodology for harmonization based on a feed in law with a modular and transparent premium for renewable electricity producers this premium considers technology costs some grid services political incentives and national priorities the proposed approach includes flexibility mechanisms to update and revise premiums to avoid windfall profits for producers and to share technology innovation benefits with electricity consumers while maintaining incentives for innovation our approach is based on the review of the main features of the german and spanish feed in laws and takes into account other necessary considerations for harmonization such as grid access funding definitions and standards ownership of rights derived from renewables and exceptions for small non commercial producers and energy intensive industries

harmonization of renewable electricity feed in laws a comment abstract this comment aims at critically analyzing some of the economic efficiency issues that are raised in the paper by munoz et al 2007 harmonization of renewable electricity feed in laws in the european union energy policy 35 3104 3114 on the harmonization of feed in law schemes for renewable electricity in the european union we comment on the choice between green certificate systems and feed in laws but pay particular attention to the implementation and design of a harmonized feed in law scheme in the comment we argue first that the approach suggested by munoz et al tends to downplay many of the practical difficulties in assessing the real costs facing investors in renewable electricity not the least since the presence of regulatory uncertainty about the marginal costs of renewable electricity may be essential for the choice between different support systems concerning the benefit side of renewable electricity promotion the munoz et al 2007 paper builds on an interpretation of the eu renewables directive that provides plenty of room for national priorities and that therefore essentially implies that harmonized support premiums per se are of little value we argue instead that a harmonized system should primarily address the international spillover effects from renewable electricity promotion not the least those related to improved security of supply in europe there exists then a strong case for disregarding the specific national benefits of renewable electricity production in the design of harmonized support systems and for instead considering international perhaps at the start bilateral policy support coordination based on entirely uniform support levels

can union labor ever cost less this paper examines the effect of unions on efficiency by estimating cost function systems over three different sets of construction projects the results show that union contractors have greater economies of scale this gives them a cost advantage in large commercial office buildings but in school and hospital construction nonunion contractors have lower costs at all output levels despite the cost differences profits for nonunion contractors in school and hospital construction are no higher than those for union contractors because the burden of higher union costs is shifted to buyers

efficiency properties of large dynamic markets this paper considers an infinitely repeated cournot market with discounting it studies the asymptotic properties of stationary perfect equilibria in such a market when the demand and production sectors are replicated indefinitely specifically the paper establishes 1 necessary and sufficient conditions for the approximate competitiveness and efficiency of stationary perfect equilibria 2 necessary and sufficient conditions for the presence of excessive competition and for the presence of limited competition at some stationary perfect equilibria and 3 conditions for approximately competitive stationary perfect equilibria to be approximately efficient the analysis focuses on the case where the market discount factor is close to unity copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

firms choice of r d intensity in the presence of aggregate increasing returns to scale abstract when firms possess unique r d assets such as innovative ideas or bright researchers and there are aggregate increasing returns to scale in r d then there can be several nash equilibria involving different levels of investment in r d in the absence of common knowledge it is not clear whether players will choose strategies that lead to nash equilibria let alone pareto preferred ones it is shown in an experimental representation of this situation that in fact the pareto preferred equilibrium may not be reached this result implies that r d policy may play a role not just in correcting the traditional market failures but also in solving a coordination problem among firms that are reluctant to research unless other firms research

labor protection and leverage this paper exploits inter temporal variations in employment protection across countries and finds that rigidities in labor markets are an important determinant of firms capital structure decisions over the 1985 2007 period we find that reforms increasing employment protection are associated with a 187 basis point reduction in leverage we interpret this finding to suggest that employment protection increases operating leverage crowding out financial leverage this result is robust across measures of employment protection and leverage and does not appear to be due to pre treatment differences between treated and control firms omitted variables unobserved changes in regional economic conditions and reverse causality heterogeneous treatment effects are consistent with our economic intuition we find that the negative effect is more pronounced in firms that are subject to frequent hiring and firing

do highly unionized companies compensate their ceos less in periods of financial distress evidence from canada in this article the author studies the strategic interaction between employee stakeholders in particular labor unions and top management and he evaluates the effect of the two parties inherent competitive rent seeking behavior on ceo pay using a panel of firms listed on the s p tsx composite index the author shows that ceo compensation withstood the financial crisis 2008 2011 despite lower and even negative corporate performance further highly unionized companies were associated with higher ceo pay in terms of non equity elements such as salary and pension allocations the presence of unions had no observed effect in reducing bonuses stock options and restricted stock units these findings have implications for the debate on income inequality and the power of unions to bring about change

cournot equilibrium with free entry the case of decreasing average cost functions this paper investigates in the context of a market for a homogeneous commodity the asymptotic properties of cournot equilibria with free entry when the size of the market increases indefinitely the analysis focuses on the case where the average cost function is always decreasing and the marginal cost function is non decreasing for all sufficiently large outputs

unionism in a competitive industry this article explores a model in which a union confronts many competitive workers firms and consumers under monopoly unionism union coverage may be incomplete then union wages and employment are insensitive to product demand variation under efficient unionism coverage can never be incomplete some union variables necessarily vary with product demand preliminary evidence on the demand independence under incomplete coverage hypothesis is presented also more structure is imposed and further hypotheses are derived and the manner in which the model can be enriched to allow for a variety of union related issues within a consistent framework is set out

walrasian equilibria as limits of noncooperative equilibria part ii pure strategies abstract we examine the connection between walrasian equilibria of a limit economy with infinitesimal firms and noncooperative cournot equilibria of approximating finite economies with significant firms nonconvex production sets decreasing returns in the aggregate and endogenous determination of the number of active firms are allowed a walrasian equilibrium is a limit of pure strategy noncooperative equilibria only if a condition loosely analogous to downward sloping demand in the partial equilibrium constant returns to scale case holds the condition is also sufficient to guarantee the existence of a robust sequence of pure strategy noncooperative equilibria which converges to the walrasian equilibrium

human resource management and performance in european firms we develop a theoretical framework to examine three hypotheses on the relationship between human resource management hrm practices and organisational performance in european firms the first is that collaborative forms of hrm practice are more strongly associated with superior firm performance than calculative forms the second is that these associations are strongest where national institutional and normative settings support them the third is that employer employee consultative committees and collective payment methods are also associated with superior firm performance the first two propositions are strongly empirically supported as is the third albeit more weakly the implications of the findings for european policy and varieties of capitalism theory are discussed

do unions capture monopoly profits this paper challenges the conclusion reached in recent studies that unions reduce profits exclusively in highly concentrated industries from their review of previous studies and their analysis of 1977 data on 367 fortune 500 firms the authors conclude that there is no convincing evidence that concentration produces monopoly profits for unions to capture moreover they find that the union wage effect is not greater in concentrated industries as suggested by the hypothesis that unions capture concentration related profits evidence is found suggesting that a firm s market share its expenditures on research and development and its protection from foreign competition provide more likely sources for union rents than does industry concentration several recent studies have found that unions reduce profits significantly and some have concluded that this profit reduction is restricted to highly concentrated industries both conclusions are important the finding that unions reduce profitability indicates that in general the cost increasing effects of unions outweigh any positive productivity effects they may bring to the workplace such a

union effects on productivity profits and growth has the long run arrived this article interprets literature examining union effects on economic performance production function studies indicate small overall union impacts on productivity positive effects where they exist appear to result from management response to decreased profit expectations and from a natural selection process lower profitability among unionized firms is well established more interesting is the possibility that unions appropriate quasi rents deriving from long lived tangible and intangible capital the connection between unions investment behavior and productivity growth emerges as a particularly fruitful line of empirical inquiry although it does not encourage a sanguine view of unionism s long run impact

union certification in ontario its effect on the value of the firm event study methodology is used to determine the effect of union certification in ontario on the expected profitability of firms raid and non raid applications and the method of certification are examined contrary to expectations we find no strong negative response to certification applications in most cases in general the more contentious the certification process the greater the negative abnormal returns this is not only true within ontario but also when our results are compared to those of the u s

consistent conjectures in a value maximizing duopoly recent literature on consistent conjectures has established that under a variety of conditions only competitive behavior is rational rationality or consistency is defined in this literature as the condition that the slope of a firm s profit maximizing reaction function must equal the conjecture made about the firm s reactions by its rivals this concept of consistency is due to bresnahan 5 who uses it to select among the many possible conjectural equilibria in duopoly as defined by bowley 3 perry 24 extends the duopoly analysis to the case of an arbitrary fixed number of identical firms as well as to the case of free entry and exit both papers show that only the bertrand conjecture in which firms accommodate rivals output changes by making equal and opposite changes is consistent when marginal costs are constant in addition perry shows that this result also holds when entry and exit are free the bertrand conjecture is identified with competitive behavior since it implies price taking and marginal cost pricing the equivalence that both papers establish between consistent conjecture equilibrium cce and competitive equilibrium under constant marginal cost may have important practical implications johnston summarizes his thorough survey of cost functions with the comment two major impressions however stand out clearly the first is that the various short run studies more often than not indicate constant marginal cost and declining average cost as the pattern that best seems to describe the data that have been analyzed 15 168 therefore the results of bresnahan and perry would seem to apply to a wide range of observed behavior making a strong theoretical case that much economic activity is truly competitive regardless of the number of firms 2 even when marginal costs are not constant and the number of firms is fixed the implication of the consistent conjectures hypothesis for profit maximizing firms is that behavior is more competitive than coumot this result in itself is important since recent work has indicated that cournot equilibrium approaches the competitive limit in the case of large economies see for

on the existence of cournot equilibrium this paper examines the existence of n firm cournot equilibrium in a market for a single homogeneous commodity it proves that if each firm s marginal revenue declines as the aggregate output of other firms increases which is implied by concave inverse demand then a cournot equilibrium exists without assuming that firms have nondecreasing marginal cost or identical technologies also if the marginal revenue condition fails at a potential optimal point there is a set of firms such that no cournot equilibrium exists the paper also contains an example of nonexistence with two nonidentical firms each with constant returns to scale production
