trade and protection in vertically related markets abstract we consider home country tariff and subsidy policies in a setting where a home firm is partially dependent on a foreign vertically integrated firm for supplies of a key input the firms are cournot competitors in the home market for the final product we show that a tariff on final product imports may cause the foreign vertically integrated firm to reduce the price charged for the input under circumstances where a simple monopoly supplier of the input would increase its price supply conditions for the input significantly affect whether imports of the input should be taxed or subsidized

towards a capability theory of innovating firms implications for management and policy author s teece dj abstract the author 2017 business enterprises lie at the core of ecosystems that drive economic development and growth in market economies yet until recently mainstream economics has mostly treated firms like homogeneous black boxes run by opportunistic managers the field of strategic management has developed a more nuanced approach to the understanding of how firms are created organized and grow how they innovate and compete and how managers manage one of the leading paradigms in the field is the dynamic capabilities framework in this paper contrasts and complementarities are drawn between dynamic capabilities and economic theories of the firm including transaction cost economics and agency theory connections to the cambridge school are highlighted including the duality between keynes s animal spirits and the dynamic capabilities entrepreneurial owner manager leibenstein s x inefficiency is juxtaposed here with d ineffectiveness knowledge based theories of the firm consistent with cambridge conventions emerge intellectual exchange between strategic management and economics is encouraged to help improve the intuition behind models of firms and the economy

market power in emission permit markets theory and evidence from the eu ets a well known result about market power in emission permit markets is that efficiency can be achieved by full free allocation to the dominant firm i show that this result breaks down when taking the interaction between input and output markets into account even if the dominant firm perceives market power in the permit market alone i then examine the empirical evidence for price manipulation by the ten largest electricity firms during phase i of the eu ets i find that some firms excess allowance holdings are consistent with strategic price manipulation and that they cannot be explained by price speculation or by precautionary purchases to insure against uncertain future emissions my results suggest that market power is likely to be an empirically relevant concern during the early years of emission permit markets

competitive outcomes in product differentiated oligopoly structure firms anticipate the competitive effects of market structure when making their entry and product type decisions the market structure variables used to explain the observed outcomes therefore derive from the related entry and product choice stage of the game as a result it is crucial to allow for correlation between unobserved factors that affect the entry and product type decisions of firms and unobservables in the outcome regressions to correct for the potential bias caused by this correlation an econometric model of equilibrium market structure is employed as a selection equation in a two step estimation procedure the second step outcome regressions are modified to reflect the market structure selection this alternative approach emphasizes the logical relationship among firms entry and product choice behavior market structure and price competition following this introduction i provide some background for the analysis of competitive outcomes in motel oligopolies section iii presents the two step estimation procedure developed to measure the effects of concentration and differentiation on outcomes this procedure is used to analyze the observed outcomes of motels located along interstate highways the data are outlined in section iv in section v i present the estimation results evidence from the analysis of these outcomes help demonstrate why motel firms find differentiation a profitable product choice strategy section vi provides some concluding remarks

sutton s sunk costs and market structure price competition advertising and the evolution of concentration sunk costs and market structure price competition advertising and the evolution of concentration the third area is critical for policy this has kept our attention focused on the other two areas not until we understand the causes and consequences of concentrated industry structure can we comment on the relevant welfare economics the positive economics of entry exit and the persistence of dominant firms and oligopolies are thus a core research topic the positive questions are very difficult like many posed by the world and not by logic traditional empirical efforts to distinguish among competing hypotheses have made little progress this is due in no small part to the complexity of the question the two main efficiency defenses of concentrated industry structure are scale economies and firm heterogeneity traditional methods use proxies for barriers to entry that could equally plausibly be proxies for the efficiencies recent theoretical work on entry and entry barriers has been very successful in teaching us about the importance of strategy irreversibility and information but it has not emphasized links to observables the observable differences between a theory predicting nearly efficient outcomes and a related theory predicting harmful barriers to entry can be very subtle to use theory in a direct way it seems we must draw dozens

measuring economies of diversification a frontier approach the purpose of this article is to improve the statistical analysis of multiproduct firm behavior specifically we are interested in modeling and estimating multiproduct technology focusing on size and product line variation thus we offer a new empirical technique that can be used to directly analyze issues such as subadditivity expansion path subadditivity economies of scope and economies of diversification although applied papers employ a wide variety of theoretical multiproduct cost concepts previous work uses nonfrontier estimation techniques we show how to introduce frontier approaches to multiproduct cost analysis that can be applied to any of these concepts and improve the statistical analysis specifically we introduce an empirical test using frontier techniques that allows for direct measures of economies of diversification at the firm specific level

the evolution of cost productivity and efficiency among us credit unions abstract advances in information processing technology have eroded the advantages of small scale and proximity to customers that traditionally enabled small lenders to thrive nonetheless the membership and market share of us credit unions have increased though their average size has also risen we investigate changes in the efficiency and productivity of us credit unions during 1989 2006 by benchmarking the performance of individual firms against an estimated order quantile lying near the efficient frontier we construct a cost analog of the malmquist productivity index which we decompose to estimate changes in cost and scale efficiency and changes in technology we find that cost productivity fell on average across all credit unions but especially among smaller credit unions smaller credit unions confronted a shift in technology that increased the minimum cost required to produce given amounts of output all but the largest credit unions also became less scale efficient over time

stochastic programming for decentralized newsvendor with transshipment abstract this paper discusses a family of two stage decentralized inventory problems using a unifying framework taxonomy depicted as a multilevel graph this framework allows us to model and link different problems of competing retailers who independently procure inventory in response to uncertain demand and anticipated inventory decisions of other retailers in this family of problems in the ex post stage the retailers exercise recourse actions in response to the realized demand and competitors chosen procurement levels for example retailers could coordinate inventory transshipment to satisfy shortage with overage based on profit sharing agreements our framework provides a unifying parsimonious view using a single methodological prism for a variety of problems equally importantly as recourse options are laid out our framework clarifies and contributes a modeling connection between problems in a clear taxonomy of models this unifying perspective explicitly links work that appeared in isolation and offers future research directions

vertical foreclosure with the choice of input specifications we develop an equilibrium model of vertical foreclosure with the choice of input specifications vertical foreclosure occurs as the upstream division of the integrated firm makes a specialized input for its sister downstream division while it would as an independent firm provide a generalized input the changes in incentives with vertical integration can be explained by the externalities the choice of a specialized input entails vertical integration allows the upstream firm to internalize the benefit of raising the rival firm s costs at the downstream level we derive conditions for equilibrium vertical foreclosure to occur and discuss its welfare consequences

development of marginal abatement cost curves for the building sector in armenia and georgia abstract armenia and georgia are taking climate change agenda seriously and contributing to efforts for mitigating global climate change through various ways including preparation of low carbon development strategies for their future economic growth the improvement of energy efficiency is one of the key elements of the low carbon development strategies this study develops a methodology to estimate marginal abatement cost mac curve for energy efficiency measures and apply in the building sector in both countries the study finds that among the various energy efficiency measures considered the replacement of energy inefficient light bulbs i e incandescent lamps with efficient light bulbs is the most cost effective measure in saving energy and reducing greenhouse gas ghg emissions from the building sector most energy efficiency improvement options considered in the study would produce net economic benefits even if the value of reduced carbon is not taken into account while the mac analysis conducted demonstrates the cost competitiveness of various energy efficiency measures in armenia and georgia the study also offers a caution to policy makers to have supplemental analysis before prioritizing the implementation of these measures or introducing policies to support them

efficiency technical change and returns to scale in large us banks panel data evidence from an output distance function satisfying theoretical regularity abstract this paper provides parametric estimates of technical change efficiency change economies of scale and total factor productivity growth for large banks those with assets in excess of 1 billion in the united states over the period from 2000 to 2005 this is done by estimating an output distance function subject to theoretical regularity within a bayesian framework we find that failure to incorporate theoretical regularity conditions results in mismeasured shadow revenue and or cost shares which in turn leads to perverse conclusions regarding productivity growth our results from the regularity constrained model show that total factor productivity of the large us banks grew at an average rate of 1 98 over the sample period however our estimates also show a clear downward trend in the growth rate of total factor productivity and our decomposition of the primal divisia total factor productivity growth index into its three components technical change efficiency change and economies of scale indicates that technical change is the driving force behind this decline

firm survival and industry evolution in vertically related populations this paper examines how the density and governance of vertically related populations affect the life chances of organizations we integrate the literatures on organizational ecology and vertical integration to develop a theory of how 1 specialized upstream industries affect downstream survival rates 2 the prevalence of different governance forms among upstream and downstream organizations moderates this relationship and 3 different forms of governance exert differential competitive pressures on focal organizations we find evidence supporting our hypotheses in an empirical examination of the downstream laser printer industry and upstream laser engine industry this paper was accepted by jesper sorensen organizations

the ranking of negative cost emissions reduction measures a flaw has been identified in the calculation of the cost effectiveness in marginal abatement cost curves maccs the problem affects negative cost emissions reduction measures those that produce a return on investment the resulting ranking sometimes favours measures that produce low emissions savings and is therefore unreliable the issue is important because incorrect ranking means a potential failure to achieve the best value outcome a simple mathematical analysis shows that not only is the standard cost effectiveness calculation inadequate for ranking negative cost measures but there is no possible replacement that satisfies reasonable requirements furthermore the concept of negative cost effectiveness is found to be unsound and its use should be avoided among other things this means that maccs are unsuitable for ranking negative cost measures as a result maccs produced by a range of organizations including uk government departments may need to be revised an alternative partial ranking method has been devised by making use of pareto optimization the outcome can be presented as a stacked bar chart that indicates both the preferred ordering and the total emissions saving available for each measure without specifying a cost effectiveness

a theoretic framework for the analysis of credit union decision making this paper presents a formal theoretic framework to analyze credit union interest rates on loans and savings deposits the unique motivational and institutional features of a credit union in particular its structure as a financial service cooperative are used to develop the objective function this is based on a comparison of the credit union s rates to alternatively available market rates and includes parameters to recognize the possibility of borrower saver conflict the principal result is that the optimal rates and reactions to exogenous changes depend critically on the preference of the organization toward financial gain to the borrowing and saving members

the growth of us credit unions abstract the growth of us credit unions during the 1990s is investigated empirically using univariate and multivariate cross sectional and panel estimation techniques univariate tests of the law of proportionate effect suggest that in general large credit unions grew faster than their smaller counterparts on average credit unions with above average growth in one period tended to experience below average growth in the next smaller credit unions tended to have more variable growth than large ones while credit unions share a common co operative philosophy they differ in terms of age profile scope for membership growth charter type and financial structure and performance in estimations of a multivariate growth model most of these characteristics are found to have a significant influence on the size growth relationship while large state chartered credit unions grew faster than their smaller counterparts the reverse was true for federally chartered credit unions in general if larger credit unions grew faster than smaller ones they tended to do so for specific reasons because their charters were less restrictive because they were more efficient or because they had a financial structure that was more conducive to growth therefore credit union growth was not random but highly systematic

the diversification and financial performance of us credit unions abstract for us credit unions revenue from non interest sources has increased significantly in recent years we investigate the impact of revenue diversification on financial performance for the period 1993 2004 the impact of a change in strategy that alters the share of non interest income is decomposed into a direct exposure effect reflecting the difference between interest and non interest bearing activities and an indirect exposure effect which reflects the effect of the institution s own degree of diversification on both risk adjusted and unadjusted returns measures a positive direct exposure effect is outweighed by a negative indirect exposure effect for all but the largest credit unions this may imply that similar diversification strategies are not appropriate for large and small credit unions small credit unions should eschew diversification and continue to operate as simple savings and loan institutions while large credit unions should be encouraged to exploit new product opportunities around their core expertise

cost raising strategies advantage rivals by raising their costs in this paper we show that strategies designed to raise rivals costs have a number of advantages over predatory pricing they are credible do not necessarily require the victim to exit and do not necessarily require the existence of classical market power the paper sets up a general model proves a number of general results and then applies the model to specific strategies involving overbuying inputs and vertical integration

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

the effects of a content requirement on a foreign duopsonist abstract this paper considers the operation of a local content requirement in a duopsony between domestic and foreign firms and demonstrates its consequences for the domestic producer of a final good it is shown that content protection may have perverse effects on a foreign firm s profits and may be welfare improving overall shifting profits from the domestic firm to both the foreign firm and domestic input producers

greenhouse gas abatement cost curves of the residential heating market a microeconomic approach in this paper we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector our research is based on a system dynamics microsimulation of private households investment decisions for heating systems to the year 2030 by accounting for household specific characteristics we investigate the welfare costs of different abatement policies in terms of the compensating variation and the excess burden we investigate two policies i a carbon tax and ii subsidies on heating system investments we deduce abatement cost curves for both policies by simulating welfare costs and greenhouse gas emissions to the year 2030 we find that i welfare based abatement costs are generally higher than pure technical equipment costs ii given utility maximizing households a carbon tax is the most welfare efficient policy and iii if households are not utility maximizing a subsidy on investments may have lower marginal greenhouse gas abatement costs than a carbon tax

the performance of universal banks evidence from switzerland abstract this paper examines the performance of swiss banks from 1996 to 1999 using a broad definition of bank output we find evidence of large relative cost and profit inefficiencies in swiss banks a more narrow definition that focuses on only traditional activities leads to efficiency estimates that are even lower we also find evidence of economies of scale for small and mid size banks but little evidence that significant scale economies remain for the very largest banks finally evidence on scope economies is weak for the largest banks that are involved in a wide variety of financial activities taken together these results suggest few obvious benefits from the trend toward larger universal banks in switzerland

economies of diversification in the us credit union sector summary significant scale economies have been recently cited to rationalize a dramatic growth in the us retail credit union sector over the past few decades in this paper we explore another plausible supply side explanation for the growth of the industry namely economies of diversification we focus on the fact that credit unions differ among themselves in the range of financial services they offer to their members since larger credit unions tend to offer a more diversified financial service menu than credit unions of a smaller size the incentive to grow in size may be fueled not only by present scale economies but also by economies of diversification this paper provides the first robust estimates of such economies of diversification for the credit union sector we estimate a flexible semiparametric smooth coefficient quantile panel data model with correlated effects that is capable of accommodating a four way heterogeneity among credit unions our results indicate the presence of non negligible economies of diversification in the industry we find that as many as 27 91 depending on the type and the cost quantile of diversified credit unions enjoy substantial economies of diversification the cost of most remaining credit unions is invariant to the scope of services we also find overwhelming evidence of increasing returns to scale in the industry

marginal abatement costs of greenhouse gas emissions a meta analysis in this paper we carry out a meta analysis of recent studies into the costs of greenhouse gas mitigation policies that aim at the long term stabilisation of these gases in the atmosphere we find the cost estimates of the studies to be sensitive to the stringency of the stabilisation target the assumed emissions baseline the way in which the time profile of emissions is determined in the model the choice of control variable co2 only versus multigas the number of regions and energy sources in the model and to a lesser degree the scientific forum in which the study was developed we find that marginal abatement costs of the stringent long term targets that are currently considered by the european commission are still very uncertain but might exceed the costs that have been suggested by recent policy assessments

estimation of a model of entry in the airline industry this paper considers the effect of an airline s scale of operation at an airport on the profitability of routes flown out of that airport the empirical methodology uses the entry decisions of airlines as indicators of underlying profitability the results extend the empirical literature on airport presence by providing a new set of estimates of the determinants of city pair profitability these estimates imply that city pair profits increase in airport presence and decrease rapidly in the number of entering firms the literature on empirical models of oligopoly entry is also extended via a focus on the role of differences between firms

political consumerism and public policy good complements against market failures political consumerism has become over the past years an ever growing phenomenon by which citizens express through their consumption their political environmental and ethical opinions this paper discusses political consumerism from an economic science perspective focusing on the link between political consumerism and public policies it wonders to what extent political consumerism may represent an effective and fair instrument against market failures overall it seems that it would be better to consider it as a complement to conventional public policies

good times bad times and vertical upstream integration abstract we consider a set of downstream firms each of which has a stochastic requirement for a particular input downstream firms can produce the input themselves yet do not trade it upstream firms produce the input to sell it through a walrasian market to downstream firms efficient pooling of capacities requires the input to be produced by upstream firms and traded in the market yet downstream firms will always vertically integrate by producing some of its own input needs a downstream firm cuts down on aggregate input demand thus depressing prices in the market

the failing firm defense this paper evaluates the welfare consequences of the failing firm defense ffd in the eu and u s merger laws to this end i combine an oligopoly model with an endogenous valuations auction model the ffd is shown to work reasonably well for consumers unless small firms are too small the ffd may however lead to total surplus losses due to a least danger to competition ldc condition which favors small and thus possibly inefficient firms it is also shown that in a multi firm setting the ffd increases the incentive for predation only when the assets are industry specific

the new industrial organization and small business the small business sector is an important part of the american economic landscape in both absolute and relative terms despite its absolute growth however the sector accounts for a diminishing share of private sector activity but its importance and changes in importance vary across industrial sectors of the economy drawing on the theoretical and empirical insights developed in recent books by john sutton we suggest that the presence or absence of endogenous strategic behaviors of the larger firms with respect to advertising promotion research and development and other sunk cost expenditures may well play an important role in explaining the differing levels of small business importance both cross sectionally and over time we conclude the paper with suggestions for research directions that could shed further light on these ideas copyright 2001 by kluwer academic publishers

optimal cross licensing arrangements collusion versus entry deterrence this paper analyzes optimal cross licensing arrangements between incumbent firms in the presence of potential entrants the optimal cross licensing royalty rate trades off incentives to sustain a collusive outcome vis a vis incentives to deter entry with the threat of patent litigation we show that a positive cross licensing royalty rate which would otherwise relax competition and sustain a collusive outcome dulls incentives to litigate against entrants our analysis can shed light on the puzzling practice of royalty free cross licensing arrangements between competing firms in the same industry as such arrangements enhance incentives to litigate against any potential entrants and can be used as entry deterrence mechanism

on the cost effectiveness of national economy wide greenhouse gas emissions abatement measures abstract this paper explores cost effective greenhouse gas abatement options for the european union member state of cyprus for those sectors of the national economy that are not subject to the european emissions trading system the analysis leads to the construction of a baseline and several alternative marginal emission abatement cost curves it addresses all economic sectors and considers all different types of mitigation measures improving energy efficiency switching to low or zero carbon fuels and inducing behavioural change towards public transport modes we apply nationally appropriate data that are mainly derived from local market information and judgement of national experts finally we present results of several sensitivity analyses which address main shortcomings of marginal abatement cost curves that have been identified in the literature and discuss the policy implications of each one of them apart from its relevance for eu member states this assessment is useful for all countries seeking guidance in their decarbonisation strategies

the usefulness of marginal co2 e abatement cost curves in austria energy efficiency measures are manifold in all economic sectors these measures can be pictured by a marginal abatement cost curve macc which is a common way to show co2 e abatement potential and its related costs in various fields in this paper we calculated the marginal co2 e abatement cost curve for austria for the first time to fulfill the need for country specific cost curves one of the strengths of such curves lies in their ability to highlight that energy efficiency measures can even have negative abatement costs the weaknesses consist of neglecting a change in energy prices the rate of diffusion and compatibility with existing technologies by using a static bottom up approach we constructed the macc for four economic sectors household service transport energy and found a national mitigation potential of 45 4 million tons co2 e the results further show that even with the measures with negative abatement costs it is possible to make the necessary co2 e mitigation to fulfill the kyoto protocol the conclusions emphasize that the curve makes a contribution to overcome one of the barriers of implementation by providing enhanced information on energy efficiency measures and its costs

multi sector model of tradable emission permits this paper presents a multi sector model of tradable emission permits which includes oligopolistic and perfectly competitive industries the firms in oligopolistic industries are assumed to exercise market power in the tradable permit market as well as in the product market specifically we examine the effects of the initial permit allocation on the equilibrium outcomes focusing on the interaction among these product and permit markets it is shown that raising the number of initial permits allocated to one firm in an oligopolistic industry increases the output produced by that firm under certain conditions raising a clean less polluting firm s share of the initial permits can lead to reductions in both the product and permit prices we discuss criteria for the socially optimal allocation of initial permits considering the trade off between production inefficiency and consumer benefit

frontrunners and laggards the strategy of environmental regulation under uncertainty the extant literature on the political economy of environmental regulation does not provide a unified theoretical explanation for three salient stylized facts first companies voluntarily invest to reduce the environmental burden that they cause under threat of regulation second ex ante estimates of the compliance cost tend to be systematically higher than ex post estimates finally regulators use limited information provided by the industry i construct a game theoretic model of environmental regulation under uncertainty with a benevolent regulator in equilibrium companies undertake voluntary action to induce regulation that raises barriers to entry this profit driven behavior is not always socially detrimental however as the regulator obtains a credible commitment to production and a more accurate estimate of the compliance cost additionally the results provide a selection explanation for the mismatch between ex ante and ex post cost estimates if companies condition compliance on the installation cost only low cost companies install in equilibrium the analysis combines regulatory capture with social welfare maximization to explain the curious combination of voluntary action and low ex post compliance cost without serious information collection by the regulator

a characterization for the negative welfare effects of cost reduction in cournot oligopoly abstract this paper characterizes the welfare effects of cost reductions in a cournot model with linear costs under linear demand a small reduction in a firm s marginal cost reduces welfare if and only if its market share is less than 1 2n 2 or equivalently its marginal cost exceeds a critical level determined by the market a large cost reduction by the firm increases welfare if and only if its magnitude is at least twice the difference between the current marginal cost and its critical value the paper also extends the results to non linear demand but the characterizations become less tractable

trends in aggregate concentration in the united states i assemble two rarely used data sets to measure aggregate concentration in the u s in the 1980s and 1990s despite the merger waves of those decades aggregate concentration declined in the 1980s and the early 1990s but rose modestly in the late 1990s the levels at the end of the decade were at or below the levels of the late 1980s or early 1990s the average size of firm and the relative importance of larger size classes of firms increased however gini coefficients for employment and payroll shares of companies showed moderate but steady increases from 1988 through 1999

endogenous protection foreign direct investment and protection building trade abstract we introduce the possibility of foreign direct investment fdi in a strategic oligopolistic setting with endogenous protection and find that a number of unique subgame perfect equilibria may arise including a new result we call protection building trade this phenomenon occurs in our model when foreign firms locating production in the home country try to increase protectionist pressures in the home country through increased exports to provide larger barriers against other foreign competitors in future periods we discuss how the foreign firm behavior surrounding significant u s protectionist actions including the vers on japanese automobiles may be consistent with protection building trade behavior

marginal abatement cost curves for policy recommendation a method for energy system analysis abstract the transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas ghg emissions in order to rank possible measures marginal abatement cost curves have become a tool to graphically represent the relationship between abatement costs and emission reduction this paper demonstrates how to derive marginal abatement cost curves for well to wheel ghg emissions of the transport sector considering the full energy provision chain and the interlinkages and interdependencies within the energy system presented marginal abatement cost curves visualize substitution effects between measures for different marginal mitigation costs the analysis makes use of an application of the energy system model generator times for south africa times geeco for the example of gauteng province this study exemplary shows that the transport sector is not the first sector to address for cost efficient reduction of ghg emissions however the analysis also demonstrates that several options are available to mitigate transport related ghg emissions at comparable low marginal abatement costs this methodology can be transferred to other economic sectors as well as to other regions in the world to derive cost efficient ghg reduction strategies

endogenous mergers in endogenous sunk cost industries abstract this paper uses an endogenous coalition formation game to derive an upper bound to industry concentration the proposed coalitional stability concept assumes that firms are endowed with foresight in that they look ahead and anticipate the ultimate outcome of their actions it is shown that while in exogenous sunk cost industries the upper bound to concentration falls as the market becomes large in endogenous sunk cost industries regardless of the size of the market arbitrarily concentrated outcomes can arise in equilibrium in addition for this second class of industries if products are sufficiently good substitutes then duopoly coalition structures can only be sustained in equilibrium if composed of sufficiently size asymmetric coalitions the results therefore complement those of sutton sutton j 1991 sunk costs and market structure cambridge ma mit press sutton j 1998 technology and market structure theory and history cambridge ma mit press

selective contracts foreclosure and the chicago school view abstract i examine a mechanism by which exclusive supply contracts may inefficiently deter entry into the market in the model the incumbent supplier selectively offers contracts only to some buyers and convinces them to consent by guaranteeing them low prices the contracts strengthen the monopoly position of the incumbent supplier and allow it to extract rents from the remaining buyers that were not offered contracts aside from the favorable contract terms buyers have another reason to consent to the exclusivity scheme the latter raises the input costs of rival buyers that were not offered contracts the model has potential applications to the recent microsoft antitrust case 1994 i define exclusive supply contract as an agreement under which an upstream firm becomes the exclusive supplier of a downstream firm the downstream firm is prohibited from buying from other suppliers

an experimental evaluation of strategic preemption abstract this paper reports the results of a series of two stage two person noncooperative games where one player can strategically preempt the other in one of our designs the subgame perfect equilibrium entails complete preemption in the other it entails partial preemption the data show that players tend to completely preempt when it is privately optimal however when partial preemption is privately optimal a non trivial fraction of players persist in choosing the non preemptive structure this may result because of occasional irrational behavior following preemptive play which induces some dominant agents to play less aggressively

competition policy in the united states an overview this paper provides a summary of the basic policies in the united states that affect the state of competition in u s markets much of the paper focuses on antitrust policy but a substantial fraction of the paper is devoted to regulatory policies for both types of policies the paper explains the basic structures of the policies and also provides discussions of recent developments copyright 1993 by oxford university press

an empirical test of the resource based theory strategic regulation in the dutch audit industry the resource based view of the firm is a recent strategic management theory that seeks to identify the resources that may provide firms with a sustainable competitive advantage this paper has two purposes first the paper relates strategic management arguments to parallel lines of reasoning in industrial organization theory and argues that strategic regulation is a major source of sustainable competitive advantage the second purpose of the paper is to report the results of an empirical test of the resource based theory on the basis of a longitudinal data set on the postwar history of the dutch audit industry a key determinant of this history proves to be strategic regulation which stimulates demand for audit services and protects rent producing resources

hubs and high fares dominance and market power in the u s airline industry this article estimates the importance of route and airport dominance in determining the degree of market power exercised by an airline the results indicate that an airline s share of passengers on a route and at the endpoint airports significantly influences its ability to mark up price above cost the high markups of a dominant airline however do not create much of an umbrella effect from which carriers with smaller operations in the same markets can benefit the article suggests a number of possible explanations for this asymmetry

technological competition and the structure of the computer industry we examine thirty years of computer industry market structure our analysis explains the persistence of dominant computer firms their recent decline and the changing success of competitive entry it emphasizes the importance of technological competition between computer platforms not firms this aspect of competition has changed little over time two things did change young platforms serving newly founded segments eventually challenged established platforms across segment boundaries through a process of indirect entry vertically disintegrated platforms have led to divided technical leadership in important segments the result is an industry with far more technological competition

upgrades switching costs and the leverage theory of tying this article investigates the role of product upgrades and consumer switching costs in the tying of complementary products previous analyses have found that a monopolist of one product will not increase its profits and reduce social welfare by tying and leveraging its monopoly position into a complementary market if the initial monopolised product is essential where essential means that all uses of the complementary good require the initial monopolised product we show that this is not true in settings characterised by product upgrades and consumer switching costs we also discuss various extensions including the role of the reversibility of tying

caveat innovator strategic and structural characteristics of new product introductions abstract the assumptions underlying models of strategic behavior by incumbents are evaluated using a case study of a ground coffee product introduction the assumption underlying earlier strategic models that the entrant does not know the incumbent s payoffs after strategic have been tested does not appear to apply instead strategic behavior is observed to hinge on ex ante uncertainty about the structure of the payoff matrix and the incremental decision making which this uncertainty spawns in this environment strategies which create noise can slow learning and delay entry

advertising s elusive economic rationale public policy and taxation advertising and its effects have been debated for well over a century in the last fewdecades a generally sceptical view of the benefits of advertising has been overturned by a series ofacademic advances in economics that detail a variety of ways in which advertising may affect theeconomy and society this academic work has however been paralleled by a growing popular andpolitical opposition to advertising and its social effects in this paper the positive economic case foradvertising is challenged by an assessment of the main channels of its influence and by a review ofthe associated empirical findings on its economic and wider impact a policy response of limitingthe tax deductibility of business advertising is explored

regional free trade and social integration this paper analyzes recent free trade arrangements from a positive political economy perspective in contrast to most other literature which fails to take into account geographical factors it is argued here that proximity and transportation costs play an important role in trade arrangements another important also largely neglected factor is the degree of social cohesion in terms of labor standards among potential trading partners a political support maximizing government will consider these factors when balancing political support from free traders and protectionists

games economists play a noncooperative view for some thirty years following world war ii most bright young economists did not go into industrial organization it was not hard to see why this was so the quick big payoffs in economics tend to go to theorists and industrial organization was a subject in which theory was not only unsatisfactory but moribund the promise of the chamberlin robinson revolution of the early 1930s had not been fulfilled and while institutional and verbaltheoretic writings on the subject were sometimes illuminating there was no hard analytic theory formalizing the structure conduct performance paradigm oligopoly in particular showed no signs of analytic tractability today the atmosphere is altogether different the profession is full of young theorists whose principal occupation is industrial organization indeed industrial organization has become the hot topic for microtheorists journals meetings and seminars abound in research on oligopoly and judging by the market this is a booming industry of course the principal reason for the change is the rise of game theory and its applications in these areas von neumann and morgenstern s great work was published in 1944 and hailed immediately by theorists von neumann and morgenstern 1944 jacob marschak indeed stated in reviewing it marschak 1946 p 1 15 ten more such books and the progress of economics is assured nevertheless it was not until the last decade that game theory came to the ascendant as the premier fashionable tool of microtheorists that ascendancy appears fairly complete bright young theorists today tend to think of every problem in game theoretic terms including problems that are easier to deal with in other forms every department feels it needs at least one game theorist or at least one theorist who thinks in game theoretic terms oligopoly theory in particular is totally dominated by the game theoretic approach the field appears to be in an exciting stage of ferment to understand why i believe that such excitement is not warranted it is necessary to step back briefly review the history of oligopoly theory before the game theory revolution and consider what it is that one wants theory to deliver

a signaling model of environmental overcompliance abstract we present a theory of unilateral regulatory overcompliance as a signaling device firms that have a competitive advantage in the use of a cleaner but more costly technology overcomply in order to signal to an imperfectly informed benevolent government that compliance costs are low thereby triggering tougher regulation we identify the conditions under which such an overcompliance signaling equilibrium arises showing that there may be over overcompliance in that firms may overcomply even when tougher regulation is not socially desirable we also discuss the differential implications of the signaling theory as compared to other theories of unilateral regulatory overcompliance
