measuring returns to scale in dea models when the firm is regulated in the standard framework of data envelopment analysis dea models the returns to scale are fully characterized using the multiplier on the convexity constraint of inefficient decision making units dmu using the projection of the input output vector on the frontier in this note we investigate how the returns to scale measurements in dea models are affected by the presence of regulatory constraints these additional constraints change the role played by the convexity constraint in order to avoid biased estimation of the returns to scale we show that the interaction between the regulatory and the convexity constraints has to be taken into account

intangible capital market share and corporate strategy this paper theoretically and empirically identifies the determinants of firm profitability and market share for twelve broadly defined us manufacturing industry groups the effects of advertising research and development and diversification on profitability and market share are econometrically tested for each industry group and corporate strategy implications of the results are considered one major result of the analysis is that research and development r d tends to be much more effective as a means of enhancing firm profitability than advertising and research and development spending decisions are more closely related to the profitability of r d than advertising decisions are related to the profitability of advertising

product market competition and managerial slack this article analyzes the effect of product market competition on managerial incentives in contrast to hart 1983a i show that competition may actually exacerbate the incentive problem the difference in results derives from our different assumptions about managerial preferences the importance of assumptions about preferences suggests that we do not yet understand the precise mechanism through which competition affects incentives

plant vintage technology and environmental regulation abstract we use data on productivity and pollution abatement costs at individual pulp and paper mills to test whether the impact of environmental regulation on productivity differs by plant vintage and technology plants with higher pollution abatement costs have significantly lower productivity levels this relationship differs greatly based on a plant s technology with productivity at integrated mills being greatly affected by abatement costs while the impact at non integrated mills is negligible plant vintage does not seem to matter with older and newer plants showing similar impacts reported abatement costs appear to substantially understate the true costs of abatement accounting for the impact of technology differences makes some difference in the estimated overall impact of environmental regulation

entry exit and performance in airline markets abstract data from the airline industry indicate that 1 entry generally is not induced by price levels substantially above the norm 2 entry reduces fares and increases output and exit increases fares and reduces output and 3 incumbents cut price and maintain output in response to entry and survivors increase both price and output in response to exit these findings cast doubt on the ability of entry to prevent or reverse price increases from anticompetitive mergers

competition risk and managerial incentives this paper examines how the degree of competition among firms in an industry affects the optimal incentives that firms provide to their managers a central assumption is that there is free entry and exit in the industry which implies that changes in the nature of competition lead to changes in the equilibrium market structure the main result is that as the intensity of product market competition increases as a result of greater product substitutability or greater market size principals unambiguously provide stronger incentives to their agents to reduce costs at the same time more intense competition also leads to more volatile firm level profits consequently managers incentives are positively correlated with firm level risk consistent with empirical evidence a decrease in the cost of entering the market has the opposite effect on incentives but still induces a positive correlation between risk and incentives

toward a public choice theory of monopoly regulation its many dimensions from the perspective of market economics this new thrust was consolidated in 1976 by s peltzman who developed a formal market model in which regulations were viewed as commodities brokered via political markets in response to bids and counter bids by those who stood to gain or to lose from specific regulation outcomes the subsequent contribution by becker 1983 added insights and institutional flesh to the stigler peltzman embryo confirming regulation as an integral component of mainstream market economics an important implication of such contributions especially those from the chicago perspective is that regulation for the most part confirms resource efficiency within market process that political markets in the absence of entry barriers are just as effective as are competitive commodity markets in achieving economic efficiency defined within a comparative institutions framework nowhere is this complacency more apparent than in the conclusion drawn by becker 1983 from a detailed formal analysis of competition among pressure groups for political influence

antitrust and technological innovation in the us ideas institutions decisions and impacts 1890 2000 abstract the history of antitrust policy in the us as it relates to technological innovation exhibits major swings every few decades between favoring concentration and favoring deconcentration this paper sketches for each period the contending ideas that frame antitrust technology policy debates the salience of these ideas in the larger antitrust policy process the institutions for agenda setting and decision making in this area the policy decisions themselves and more speculatively the impacts of these decisions on technological innovation and industrial development the paper concludes with a preliminary attempt to identify the cyclical secular and static processes that have shaped the history of this policy area and to use this analysis to inform future policy makers

incentive compatible regulation of a foreign owned subsidiary abstract transfer prices are administered charges for intra firm transfers of factors of production for a multinational firm transfer prices for international transfers provide the means to redistribute costs and increase global profits given variations in national tax and profit repatriation policies local regulation of a subsidiary may thus be necessary to limit the welfare costs of strategic transfer pricing prusa journal of international economics 1990 28 155 172 characterizes the welfare maximizing regulations for a monopoly subsidiary that induce the firm to report transfer prices truthfully we show however that it can be more efficient to implement regulations that encourage the firm to misrepresent its true transfer costs

the impact of pollution abatement investment on productivity change anempirical comparison of the u s germany and canada since environmental quality became an important focus of government regulations in most industrialized countries in the early 1970s many researchers have assessed the impact of these regulations on economic performance for example leontief and ford 11 and pasurka 15 investigated the impact that environmental protection costs had on prices in the u s walter 24 calculated the effect of pollution abatement expenditures on u s trade and robinson 19 measured the distributional impact of the burden of industrial pollution abatement a related issue involves the productivity consequences of environmental regulations in this paper we address this issue by considering the impact of pollution abatement investment on productivity growth

estimation of cross country differences in industry production functions abstract international trade economists typically assume that there are no cross country differences in industry total factor productivity tfp in contrast this paper finds large and persistent tfp differences across a group of industrialized countries in the 1980s the paper calculates tfp indices and statistically examines the sources of the observed large tfp differences across countries two hypotheses are examined to account for tfp differences constant returns to scale production with country specific technological differences and industry level scale economies with identical technology in each country the data support the constant returns different technology hypothesis over the increasing returns same technology hypothesis

industry equilibrium uncertainty and futures markets abstract this paper studies competitive long run industry equilibrium with uncertainty and futures trading we also provide a long run analysis of futures trading instead of the conventional short run analysis it is shown without using a general equilibrium model that given uncertain demand and risk aversion a bias backwardation or contango arises in long run industry equilibrium given risk neutrality such a bias however disappears we find that the occurrence of the bias depends not only on the existence of a risk premium but also on the length of the period considered each risk averse firm operates at a less efficient scale and moreover an expected spot price never accords with marginal cost when the expected spot price is less than marginal cost the risk averse firm can secure profit by selling futures contracts more than the amount of its output in the presence of production supply uncertainty a risk neutral firm operates with excess capacity under additive risk while the firm operates with proper capacity under multiplicative risk the key lies in whether its average cost curve is shifted by production risk

symmetric or asymmetric price adjustments in the oil market an empirical analysis of the relations between international and domestic prices in the federal republic of germany 1972 89 abstract this paper investigates how german consumer and wholesale prices for gasoline and light heating oil react to changes in the corresponding rotterdam prices monthly data from 1972 to 1989 are employed and the subperiods of the 1970s 1972 to 1979 and 1980s 1980 1989 are distinguished error correction models are estimated to seperate long run equilibrium relations and short run adjustment processes for the 1980s we find rapid symmetric and full adjustment of the german prices to the rotterdam prices whereas during the 1970s we find some asymmetries and at least for gasoline the adjustment processes took considerably more time

the flypaper effect and competition in the local market for public goods in this paper we explore how the ability of bureaucrats to extract resources from their community may be limited by competition in the local market for public goods specifically we examine intergovernmental aid as a resource bureaucrats seek to control intergovernmental aid has been found to be more stimulative of local government expenditures than predicted by neo classical economic theory in this research the flypaper effect is used as an indicator of the ability of bureaucrats to control local resources in excess of local demand and preferences we empirically relate variation in the flypaper effect to the extent of competition in the local market for public goods competition does not consistently limit the flypaper effect the implications of this finding for theories of competition in the local market for public goods are then discussed

the role of acquisitions in foreign direct investment evidence from the u s stock market this paper examines foreign direct investment by studying shareholder wealth gains for 1273 u s firms acquired during the period 1970 1987 three findings stand out first cross border takeovers are more frequent in research and development intensive industries than are domestic acquisitions furthermore in three fourths of cross border transactions the buyer and seller are in related industries these industry patterns suggest that costs and imperfections in product markets play an important role in foreign direct investment second targets of foreign buyers have significantly higher wealth gains than do targets of u s firms this cross border effect is comparable in size to the wealth effects of all cash and multiple bids two effects receiving substantial attention in the finance literature and is robust to inclusion of these two variables third while the cross border effect on wealth gains is not well explained by industry and tax variables it is positively related to the weakness of the u s dollar indicating a significant role for exchange rate movements in foreign direct investment

pollution abatement activities and traditional productivity abstract this study models the joint production of good and bad output production and calculates traditional productivity when bad output production is regulated and when it is unregulated we apply this model to data for u s coal fired electric power plants for 1985 1995 and compare rates of productivity and technical change to gain an understanding of the association between pollution abatement activities and traditional rates of productivity and technical change while traditional productivity and technical change associated with abatement activities decline we conclude they are not statistically significant

how do environmental regulation and environmental decentralization affect green total factor energy efficiency evidence from china abstract green development is critical for china s economic transformation enhancing green total factor energy efficiency hereafter gtfee is vital to emission reduction and to win win industrial development this study uses the panel data of 30 chinese provinces for the period 2005 2016 to investigate the relationship between environmental regulation and china s gtfee the spatial durbin model is employed to control for the possible spatial spillover effect a dynamic threshold panel model that can effectively address the endogeneity problem and regional heterogeneity is utilized to examine the potential non linear relationship between environmental regulation and gtfee under different conditions of environmental decentralization the estimation results indicate that there is a significant u shaped relationship between environmental regulation and china s gtfee with the further expansion of environmental decentralization the local government s autonomous choice of pollution control is improved the improvement of environmental decentralization can lead to negative moderating effect of environmental regulation on gtfee additionally the regression results of dynamic threshold model show that environmental decentralization can increase the negative influences of environmental regulation on gtfee interestingly the non linear impact of environmental regulation on gtfee is dependent on the specific type of environmental decentralization higher degree of environmental decentralization can lead to an increase in the restraining effect of environmental regulation on gtfee however an improvement in the decentralization of environmental supervision and environmental monitoring can increase the negative influences of environmental regulation on gtfee

shadow prices environmental stringency and international competitiveness abstract empirical tests of the relationship between international competitiveness and the severity of environmental regulations are hampered by the lack of pollution abatement cost data for non u s countries the theory of the firm suggests that environmental stringency can be measured by the difference between a polluting input s shadow price and its market price we make a first attempt at quantifying such a measure for two industries located in nine european oecd countries overall we provide i a new approach to measure cross country regulatory differences in that we use a theoretically attractive measure of industry specific private compliance cost and ii empirical estimates that are an attractive tool for researchers and policymakers who are interested in examining how economic activity is influenced by compliance costs

the meta production function approach to technological change in world agriculture abstract an alternative meta production function for agriculture is estimated with the cross section data for 43 countries and three years 1960 1970 and 1980 constructed and used by kawagoe hayami and ruttan and hayami and ruttan in their studies by allowing for country specific efficiency factors and using a flexible functional form the transcendental logarithmic production function strikingly different results from those of kawagoe hayami and ruttan are obtained in particular it is found that elasticity of output with respect to machinery is variable and the degree of local returns to scale is not constant and increases with the usage of machinery

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

a note on free entry under uncertainty the role of asymmetric information in a model of competing managerial firms i show that the equilibrium number of firms decreases with uncertainty if entry is relatively more costly than monitoring the result adds to the earlier contributions and is consistent with the available evidence

is there a causal effect of concentration on persistent profitability differentials this article searches for a causal effect of industry concentration on estimates of persistent profitability differentials i offer solutions to identification problems that plague related analyses by applying an iv and a natural experiment this is the first study that explains estimates of persistent profit differentials using business segments data allowing to match micro and industry level data more consistently testing linear relations critical concentration levels and interactions with mobility barriers i find no evidence that concentration has any positive effect on long run profitability differences results rather tend to point to a statistically and economically significant negative causal effect

contestable markets an uprising in the theory of industry structure comment a situation traditionally identified as conducive to imperfect competition is when average costs decline and the cheapest scale of production is large relative to the size of the market however some of the more recent literature on industrial organization has emphasized a supposed distinction between fixed costs of production and sunk costs of production a point frequently made is that while the possibility of sunk costs can create genuine barriers to entry pure fixed costs per se do not inhibit competitive market performance this approach finds its logical extreme in the norm or abstraction of perfect contestability perfect contestability is essentially a theory of the polar case of frictionless entry and exit as william baumol stated a contestable market is one into which entry is absolutely free and exit is absolutely costless p 3 certainly this is the most reasonable interpretation of a situation where potential entrants feel free to disregard an incumbent s price response suppose every potential and actual producer has access to the same technology in a perfectly contestable market there are no set up or shut down losses the main result is that even with declining average costs of production the incumbent firm does not dare to post a price higher than average cost price above cost invites being undercut by a hit and run shadow entrant capable of producing at the same flow rate and at identical unit cost during just the briefest instant of time i argue that this line of reasoning is misleading perfect contestability gets around the problem of increasing returns only by in effect assuming it away a hit and run technology makes the firm behave as if it is competitive in a market precisely because the convexity preconditions for competition are de facto being met in that market this comment shows that strictly speaking there is no such thing as a pure fixed cost unless there are sunk costs located somewhere in the relevant production technology all costs are variable as a matter of formal theory you cannot have a range of decreasing average cost without sunk costs presumably there is also an approximation theorem which states that when sunk costs are close to being negligible then average production costs are practically nondecreasing perfect contestability holds approximately in a market only to the extent that production costs for the market are approximately nondecreasing my discussion will be restricted to the familiar case of a single well defined homogeneous fully divisible commodity while more general approaches are possible for the sake of simplicity the following definition is used the average cost function a c y t describes say the minimum cost per unit of output produced at a uniform flow rate y throughout the time interval 0 t especially in applications to industrial organization theory it is essential to remember that cost functions are not generally timeless and that writing ac as a function of y alone can be dangerously vague behind the free entry and exit of a hitand run technology in a perfectly contestable market is the abstraction of no sunk costs investments are fully reversible because nothing is lost in setting up or shutting down production

contestability vs competition once more baumol willig and other advocates of contestability theory continue to urge the idea not only for its insights but also as a clear basis for many antitrust and regulatory decisions yet the limits of the theory remain the three key assumptions are extremely strict and two of them are in mutual conflict the theory is not robust to imperfections in order to displace effective competition with contestability baumol must adopt a sequence of implausible propositions which unfortunately have little analytical or empirical basis

pollution abatement and productivity growth evidence from germany japan the netherlands and the united states the passage of environmental legislation was accompanied by concerns about its potential detrimental effect on productivity we assume inputs can be assigned to either abatement activities or good output production this allows us to specify regulated and unregulated production frontiers to determine the association between pollution abatement and productivity growth we then employ our assigned input model to determine the association between productivity and abatement activities for manufacturing industries in germany japan the netherlands and the united states

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

contestability reconsidered the meaning of market exit costs abstract this paper analyses the main result of the contestable market approach namely that potential competition reaches its maximum power if market entry and exit is costless and newcomers can use the hit and run strategy different time lag structures are considered average cost pricing turns out to be no equilibrium if there are no market exit costs furthermore exit costs don t necessarily create a barrier to entry but may even strengthen the discipline arising from the threat of entry

environmental innovations and firm profitability unmasking the porter hypothesis we examine impacts of different types of environmental innovations on firm profits following porter s sci am 264 4 168 1991 hypothesis that environmental regulation can improve firms competitiveness we distinguish between regulation induced and voluntary environmental innovations we find that innovations which do not improve firms resource efficiency do not provide positive returns to profitability however innovations that increase a firm s resource efficiency in terms of material or energy consumption per unit of output have a positive impact on profitability this positive result holds for both regulation induced and voluntary innovations although the effect is greater for regulation driven innovation we conclude that the porter hypothesis does not hold in general for its strong version but depends on the type of environmental innovation our findings rest on firm level data from the german part of the community innovation survey 2008 cis 2008
