cooperative and noncooperative r d in duopoly with spillovers contrary to the usual assumption made in most oligopoly models relations among firms are seldom of a wholly cooperative or noncooperative type in many situations they compete in some fields while they cooperate in others an important example is the case of cooperative research efforts bringing fierce competitors together two types of agreement are observed first r d cooperation can take place at the so called precompetitive stage companies share basic information and efforts in the r d stage but remain rivals in the market place 1 a second type of agreement involves an extended collusion between partners creating common policies at the product level the usual justifications of this extension are the difficulties of protecting intellectual property the idea is then to allow partners who have achieved inventions together to also control together the processes and products which embody the results of their collaboration in order to recuperate jointly their r d investments 2 what could be expected from these types of agreement is a reduction in r d expenditures because of less wasteful duplication and a reduction of total production because of more reprinted from the american economic review 78 5 1133 1137 1988 center for operations research econometrics 1348 louvain la neuve belgium we are grateful to jean

are judges leading economic theory sunk costs the threat of entry and the competitive process in this paper we attempt to bring theoretical form to a particular entry argument that has found favor in the courts we suggest that sunk costs may not be a major impediment to entry when a group of customers can commit to an entry enhancing strategy buyers have strong incentives to adopt such strategies because they benefit directly from the resulting lower prices the simplest example involves a large buyer that is able to guarantee an entrant a market for its product long term contracts or even informal purchase commitments backed by customer reputation may also allow the entrant to obtain a guarantee of sufficient business to make the entry profitable once entry is thought likely to occur the existing competitors may be unwilling to attempt a price increase of any magnitude thus the threat of entry can maintain competitive prices even in the presence of sunk costs in section ii we motivate the analysis by discussing the current controversy over the role entry conditions play in an antitrust merger review then we discuss the necessary assumptions for a model of how the threat of entry can deter any price increase in the presence of sunk costs we note that these conditions are different from those commonly used in the economic literature

limited liability and incentive contracting with ex ante action choices abstract this article examines a principal agent model of financial contracting in which a risk neutral entrepreneur agent makes an unobservable ex ante effort choice while employing the investment funds of a risk neutral investor principal the key innovation is that the investment contract is subject to statutory liability limits given these liability limits two settings are considered one in which the investor payoff function is also constrained to be monotonically nondecreasing in firm profit and another in which no such monotonic contract constraint is imposed in the former case a standard debt contract is shown to emerge and a first best effort choice is not achieved in the latter setting the optimum is characterized by a live or die payoff function and a first best effort level may or may not be realized

optimal management of an r d budget abstract this paper characterizes the optimal allocation of a budget between several stages of an r d project when intermediate stages are profitable the optimal allocation involves greater expenditures in early stages increasing the budget does not necessarily increase expenditures in every stage but does increase the budget that remains unspent at each stage a simple necessary and sufficient condition is given for the optimality of bold play the spending of all remaining budget on the current stage if profits are realized only after all stages are successfully completed decreasing returns in the innovation production function implies that the optimal strategy is to spread the budget evenly between the stages of the r d project

breaking up a research consortium inter firm r d collaborations through contractual arrangements have become increasingly popular but in many cases they are broken up without any joint discovery we provide a rationale for the breakup date in r d collaboration agreements more specifically we consider a research consortium initiated by a firm a with a firm b b has private information about whether it is committed to the project or a free rider we show that under fairly general conditions a breakup date in the contract is a second best optimal screening device for firm a to screen out free riders with the additional constraint of renegotiation proofness a can only partially screen out free riders entry by some free riders makes sure that a does not have an incentive to renegotiate the contract ex post we also propose empirical strategies for identifying the three likely causes of a breakup date adverse selection moral hazard and project non viability

unforeseen contingencies and incomplete contracts we scrutinize the conceptual framework commonly used in the incomplete contract literature this literature usually assumes that contractual incompleteness is due to the transaction costs of describing or of even foreseeing the possible states of nature in advance we argue however that such transaction costs need not interfere with optimal contracting i e transaction costs need not be relevant provided that agents can probabilistically forecast their possible future payoffs even if other aspects of the state of the nature cannot be forecast in other words all that is required for optimality is that agents be able to perform dynamic programming an assumption always invoked by the incomplete contract literature the foregoing optimality result holds very generally provided that parties can commit themselves not to renegotiate moreover we point out that renegotiation may be hard to reconcile with a framework that otherwise presumes perfect rationality however even if renegotiation is allowed the result still remains valid provided that parties are risk averse

the welfare effects of third degree price discrimination in the author examines third degree price discrimination by an upstream monopolist in an intermediate good market discrimination is motivated by the fact that downstream firms differ in their abilities to integrate backward into supply of the input the author shows that under reasonable specifications of equilibrium price discrimination leads to all buyers facing higher input prices in other cases discrimination raises some prices and lowers others the author derives conditions under which discrimination lowers welfare by reducing total output and shows that in some markets discrimination will raise welfare by preventing socially inefficient backward integration copyright 1987 by american economic association

cooperatives as entrants a potential shortcoming of game theoretic models in industrial organization is their failure to consider consumers as players we introduce a customer coalition a cooperative as a potential entrant and compare the cooperative entry threat with that posed by the usualforprofit entrant we identify four fundamental distinctions between cooperative andfor profit entrants and demonstrate that the strategic interplay between a cooperative and an incumbent firm may differ markedly from that between the incumbent and a for profit entrant the results impart a prospectively powerful role to potential cooperatives in beneficially regulating free market performance

endogenous r d symmetry in linear duopoly with one way spillovers a duopoly model of cost reducing r d cournot competition is extended to study the endogenous timing of r d strategic investment under the assumption that r d spillovers only flow from the r d leader to the follower sequential and simultaneous play at the r d stage are compared in order to assess the role of technological externalities in stimulating or attenuating endogenous firm asymmetry the only timing structure of the r d stage sustainable as subgame perfect nash equilibrium involves simultaneous play and zero spillovers

co determination and innovation this paper examines the effect of the german co determination law of 1976 mitbestg on the innovative activity of german firms co determination applies to firms with 2 000 employees or more data from 1971 1976 and 1981 1990 on 148 firms are used to compare the number of patents granted to co determined firms before and after the introduction of the law several control variables are applied and in particular in order to avoid a possible bias from specific effects of firm size we compare the co determined firms with others before and after 1976 the results do not support the view that co determination slows down technological progress and reduces innovativity

managerial incentives and the price effects of mergers most analysis of market power assumes that managers are perfect agents for shareholders this paper relaxes that assumption when managers of a multi product firm exert unobservable effort to improve product quality there is a trade off between providing adequate effort incentives and ensuring sufficient price coordination between the product divisions this makes some intra firm price competition optimal explaining why many multi product firms allow for competition between divisions when there are effort spillovers the optimal amount of price competition can be as great as when the products are under separate ownership even with some profit sharing intra firm price competition can reduce quality adjusted price which has important implications for antitrust policy

managerial compensation contract and bank bailout policy abstract under the incomplete contract framework we consider an optimal regulatory policy for motivating bank equity owners and bank managers to restructure the bad loans of their banks in the presence of managerial compensation contracts with stock options the regulatory policy studied in this paper is mainly concerned with the design of repayment schedules in the scheme of injection of cash funds into insolvent banks by the regulator we show that the regulator cannot necessarily attain the social optimal allocation by injecting cash funds into insolvent banks through the purchase of subordinated bonds with the risk free interest rate however even in that case we also suggest that if the regulator injects cash funds into active restructuring banks through the purchase of subordinated bonds or preferred stocks with less stringent repayment conditions and nationalizes passive restructuring banks the regulator can attain the social optimal allocation by performing such a non linear injection scheme under certain conditions

disclosure of know how in research joint ventures abstract research joint ventures rjvs usually face technical uncertainty their expected cost typically depending on the know how disclosed by the partners however the partners have little incentive to share their know how when they are simultaneously competitors in other markets in this setting we show that sometimes profitable rjvs do not start when the disclosure of know how is not contractible and characterize the incentive contracts when they exist we also analyze rjvs as an alternative to licensing contracts for the transmission of know how finally we show that the eec s technology policy based on cost subsidies has negative consequences on firms incentives to share know how

dynamic r d with spillovers competition vs cooperation abstract we investigate dynamic r d for process innovation in a cournot duopoly where firms may either undertake independent ventures or form a cartel for cost reducing r d investments by comparing the profit and welfare performances of the two settings in steady state we show that private and social incentives towards r d cooperation coincide for all admissible levels of the technological spillovers characterising innovative activity we also evaluate the whole history of the dynamic system along the transition to the steady state showing that the conflict between private and social incentives does not necessarily emerge

cooperative and noncooperative r d in an oligopoly with spillovers this paper examines the positive and normative effects of cooperative r d whereby member firms commit themselves to the joint profit maximizing level of r d in a precompetitive stage but remain fierce competitors in the product market vis a vis noncooperative r d socially first best r d and socially second best r d in the presence of sufficiently large r d spillovers neither noncooperative nor cooperative equilibria achieve even second best r d levels in the absence of spillover effects however while the cooperative r d level remains socially insufficient the noncooperative level may overshoot first and second best levels of r d copyright 1992 by american economic association

forbearance deposit insurance pricing and incentive compatible bank regulation abstract this paper examines the incentive compatible role of regulatory forbearance policy in the context of optimal bank regulation under moral hazard we show that when a bank s asset portfolio returns have market risk the regulator can influence the bank s choice of ex ante risk by delaying the closure of an insolvent bank the optimal closure policy involves co ordinating the closure decision with market wide performance such a policy may significantly alleviate the bank s ex ante risk shifting problem furthermore even fixed rate deposit insurance can be optimal when combined with a sound forbearance policy and a minimum capital standard

the stability of joint ventures reciprocity and competitive rivalry the focus of the following empirical analysis is the influence of reciprocity and long term relationships on the stability of joint ventures these cooperative incentives are offset by industry structural conditions which may promote competitive rivalry among the partners to separate these effects on joint venture survival the hypothesized relationships are proxied by variables drawn from industry and questionnaire data and estimated under a hazard model specification a theoretical implication of the findings is to suggest a shift of attention from the transaction to the economic relationship as the unit of analysis copyright 1989 by blackwell publishing ltd

optimal cartel trigger price strategies abstract a dynamical model of industry equilibrium is described in which a cartel deters deviations from collusive output levels by threatening to produce at cournot quantities for a period of fixed duration whenever the market price falls below some trigger price in this model firms can observe only their own production level and a common market price the market demand curve is assumed to have a stochastic component so that an unexpectedly low price may signal either deviations from collusive output levels or a downward demand shock

the past and future of commercial banking viewed through an incomplete contract lens commercial banks emerged at a time when contracts were quite incomplete and property rights insecure they typically offered demand deposits made loans on demand and were regulated each of these aspects of the institutional structure were essential in helping the bank provide the twin functions of liquidity and safety i argue that recent theories of banking which i collectively refer to as incomplete contract theories of banking explain well the origins of banking i also claim that they can explain recent changes in banking as th e informational legal and property rights environment has improved there appear to be fewer synergies between various aspects of the traditional institutional structure of the bank it is now time to think whether there is anything special about the institutional form of the bank or whether all that is special is that it is regulated

uncertainty spillovers and cooperative r d abstract this paper extends the literature on cooperative r d in an oligopoly with spillovers the model has three new features it introduces uncertainty focuses on spillover of innovation instead of effort spillover and offers a new definition of the research joint venture rjv the rjv is an arrangement to coordinate r d efforts and also to share the innovation firms form an rjv only if the innovation raises flow industry profit but independently of the speed of spillovers and the degree of uncertainty the model is robust when we allow for licensing the single lab endogenous spillovers and r d effort spillovers

the folk theorem with imperfect public information the authors study repeated games in which players observe a public outcome that imperfectly signals the actions played they provide conditions guaranteeing that any feasible individually rational payoff vector of the stage game can arise as a perfect equilibrium of the repeated game with sufficiently little discounting the central condition requires that there exist action profiles with the property that for any two players no two deviations one by either player give rise to the same probability distribution over public outcomes the results apply to principal agent partnership oligopoly and mechanism design models and to one shot games with transferable utilities copyright 1994 by the econometric society

an analysis of cooperative research and development i analyze the effects of cooperative research whereby member firms agree to share the costs andfruits of a research project before they undertake it in this model industrywide agreements tend to have socially beneficial effects when the degree ofproduct market competition is low when there are r d spillovers in the absence of cooperation when a high degree of sharing is technologically feasible and when the agreement concerns basic research rather than development activities i show that a royalty free cross licensing agreement among any number offirms lowers the equilibrium level of innovation even though it increases the efficiency of r d through sharing

cooperative and noncooperative r d in duopoly with spillovers comment claude d aspremont and alexis jacquemin 1988 employ a simple yet elegant symmetric duopoly model of r d and spillovers to compare several equilibrium concepts these concepts include 1 the two stage noncooperative solution 2 the two stage mixed game 3 the two stage fully cooperative solution 2 and 4 the social planner s optimum 3 for each of the cases stated above they computed the equilibrium levels of output q q1 q2 and r d xl x2 x and the required second order conditions they report i for large spillovers i e b 0 5 x x x and q q q q and ii for small spillovers i e 3 x 2x x and q q q q where x denotes a firm s r d level q denotes total industry output denotes the social optimum denotes the fully cooperative model the noncooperative two stage case and the mixed game 3 is the spillover parameter here we show that comparing the pure cooperative and the pure noncooperative solutions as defined by d aspremont and jacquemin is only meaningful when the noncooperative solution is stable that is when spillovers are not too small we find that for very small spillovers in our example this occurs when 3 0 17 the d aspremont jacquemin observation holds because the noncooperative model is unstable the importance of this result rests on the fact that even though the output reaction functions cross correctly when 3 0 17 the r d reaction functions do not when 0 17 0 41 stability obtains but r d levels are higher in the noncooperative case than the fully cooperative one for large spillovers the d aspremont jacquemin result is confirmed moreover we find that the introduction of spillovers in the case of the noncooperative model tends to promote stability in the case of the cooperative model however as the level of spillovers is increased an equilibrium ceases to exist

fight fold or settle modelling the reaction to ftc merger challenges i introduction scholars studying law and economics have identified four stages through which every legal dispute moves the first stage involves an alleged injury which leads to the legal dispute second the injured party decides whether to advance a claim once a claim is advanced the plaintiff and defendant may negotiate to settle the claim if the negotiation fails the dispute moves to litigation by subdividing the legal process into these four stages it is possible to study the interaction at any one stage in greater detail this paper models the third stage of this process in an antitrust setting the interaction between the federal trade commission ftc and private parties interested in consummating horizontal mergers that may adversely affect competition the ftc must decide whether to advance a claim against the merger and seek to block the transaction if such a claim is made the merging parties may fight forcing a resolution of the dispute through litigation by moving forward with the transaction they may also fold abandoning the transaction or settle entering into an agreement with the government to resolve the issues underlying the merger challenge this decision to fight fold or settle is somewhat more complicated than the standard settle or litigate question because the prospective nature of the alleged competitive injury gives the defendant an opportunity to abandon the transaction before the injury occurs our basic hypotheses with respect to this process are that firms decisions depend not only on the competitive merits of the ftc s case but perhaps more importantly on the political conglomerate and financial nature of the relevant transaction and how the nature of the case fits into the merger review process section ii presents the background for the analysis by discussing the institutional structure of the ftc explaining the merger review process and then presenting an overview of a firm s options when faced with a decision by the ftc to block a merger section iii models the decision faced by firms defines the equations to be estimated and surveys the data set of ftc merger challenges a multinomial logit model of a firm s fight fold or settle decision is estimated in section iv followed by an interpretation of the results and an application of the model using both historical data and information from mergers proposed during fiscal 1992 and 1993 we find that the level of the competitive overlap associated with the relevant transaction is an important determinant of firms fight fold or settle decisions in particular if the competitive overlap involves a small percentage of the transaction firms generally prefer to reach a negotiated settlement with the commission in such cases the settlement decision appears unaffected by the underlying merits of the ftc s legal position in other cases the merits of the case may play a role in the firm s litigation decision we also find that the potential efficiencies offered by the merger affect the firms decision making process with firms more likely to fight and less likely to settle if the merger is expected to generate efficiencies ii issues in merger enforcement background on the federal trade commission the ftc is a government agency charged along with the antitrust division of the department of justice with enforcing the antitrust laws much of the antitrust casework involves the evaluation of the competitive effects of proposed horizontal mergers 1 to interdict a proposed merger the ftc must obtain a preliminary injunction from a federal district court with possible review from the relevant court of appeals if the court declines to issue the injunction the firms are free to merge though the ftc can initiate a lengthy court process to attempt to obtain a permanent injunction against the merger commission decisions are made by a majority vote of the five commissioners each of whom are appointed by the president and confirmed by the senate for terms of up to seven years

inter firm cooperation with imperfectly appropriable research abstract inter firm collaboration in pre competitive research is not always beneficial rather its effectiveness in raising social benefits relative to a non cooperative setup depends on both the nature of the agreement and the technological and market conditions of the industry in question joint ventures that simply allow members to coordinate their actions in pre competitive research can restore firm incentives for both pre competitive research and development in the presence of high knowledge spillovers and poor opportunities for innovation joint ventures which additionally improve the dissemination of information among member firms raise social benefits whenever the opportunities for innovation are not exceptionally good even in the presence of relatively insignificant spillovers

modelling imperfectly appropriable r d via spillovers abstract we provide an extensive comparison of the well known r d models of d aspremont jacquemin and kamien muller zang exposing full or partial conflict in key conclusions and policy prescriptions using a mix of formal and or intuitive criteria we argue that the first model is of questionable validity for large spillover values the latter being characterized by jointly increasing returns to scale in the r d process an argument leading to equivalence between the two r d processes but not to agreement on some key conclusions is exposited in conclusion the models emerge as fundamentally different although a unilateral shift in the cost function of the first leads to agreement in all equilibrium outcomes

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

buyers strategies entry barriers and competition in markets where sellers have customer specific investments and buyers can make credible but costly commitments to switch suppliers buyers strategies attenuate the market power of sellers furthermore since current prices and a buyer s decision to switch suppliers are related limit pricing becomes an equilibrium limit prices increase with the time it takes a buyer to switch suppliers and with buyers switching costs but fall with the level of sunk investments thus sunk investments may restrain the sellers ability to exert market power the paper questions then the standard inverse relationship between market performance and sunk investments

strategic entry deterrence in analyzing deterrence of large scale entry two classes of entry barriers may be distinguished an innocent entry barrier is unintentionally erected as a side effect of innocent profit maximization in contrast a strategic entry barrier is purposely erected to reduce the possibility of entry two types of innocent barriers may also be distinguished a postentry absolute advantage has the property that if entry did occur the established firm would be at a profit advantage over the entrant examples are superior technology or product design patents and lower input prices a preentry asymmetry advantage arises from the fundamental preentry asymmetry between established firm and potential entrant before the entrant makes his entry decision the established firm has already committed resources this prior existence gives first move advantages the preentry asymmetry is independent of symmetry or asymmetry in the rules the equilibrium concept of the postentry game that might ensue even if the postentry game will be played according to nash cournot or entrant as leader rules the preentry leadership

collusion and predation under almost free entry abstract this study investigates the degree of cooperation that firms can support in the absence of significant barriers to entry a free entry subgame perfect equilibrium is defined by q n where q is the collusive output rate and n is the number of active firms such that there is no incentive for an active firm to deviate output from q and there is no incentive for a potential entrant to enter the industry it is shown that for all n 1 if the discount factor is sufficiently high there exists a free entry equilibrium in which active firms sustain a non trivial degree of cooperation cooperation is supported by active firms credibly threatening to respond to entry with a period of aggressive competition

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

the degree of spillovers and the number of rivals for maximum effective r d abstract the amount of cost reduction or effective r d that results in a symmetric sequential nash equilibrium with quadratic payoffs and differentiated goods is shown to increase with spillovers in oligopolies with a few rivals and to achieve a maximum for spillovers that are not perfect in industries with many firms similar tendencies apply for consumer surplus profits and static welfare more rivals typically lead to reduced investments output and profitability while consumer surplus and welfare increase or at least do not decrease limited entry in markets with a few rivals may enhance innovative investments profitability and consumer surplus if only product differentiation and spillovers are sufficiently high and r d costs sufficiently low too many rivals will then again lead to reductions and a decrease in static welfare

cooperation spillovers and price competition in experimental markets i introduction both competition and cooperation are important for the successful functioning of many economic systems for example firms compete in markets but they also cooperate with one another through arrangements such as research joint ventures lobbying cooperative marketing agreements and strategic alliances in this paper we use experiments to examine how competitive interactions affect agents propensity to cooperate we are interested in studying spillovers that may involve cooperation in one domain such as a research joint venture and competition in another such as in a market 1 cooperation could weaken competition perhaps promoting collusion or market competition could reduce incentives for non market cooperation these behavioral spillovers could go in either direction they are distinct from another type of spillover through knowledge externalities that occur in research and development r d when the innovator cannot fully appropriate the gains to innovation leading potentially to a socially inefficient level of research debondt 1996 2 as discussed below behavioral spillovers have been shown in experiments to increase cooperation in otherwise competitive environments for example through establishing cooperative precedents a large body of theoretical research has focused on firms cooperating in research joint ventures and how this impacts competition in output markets for example cooper and ross 2009 examine the mechanism by which agreements to cooperate in one market can have negative effects on competition in other markets even in situations when these markets are not linked via costs or demand cabral 2000 shows that product market prices are affected by r d agreements between firms caloghirou ioannides and vonortas 2003 lambertini poddar and sasaki 2003 and poyago theotoky 2007 also discuss the impact of forming research joint ventures on product markets and cartel formation 3 empirical work using field data has provided creative indirect evidence on the collusive potential of research joint ventures by exploiting natural policy experiments although the extent of this evidence is limited goeree and helland 2010 for example show that research joint ventures facilitate collusion because they became less popular following an enforcement policy change leniency that made collusion less attractive policy experiments such as these are often required since systematic collusion often goes undetected by authorities duso roller and seldeslachts 2010 also examine the link between research joint ventures and collusion using data from the u s national cooperation research act that granted certain research joint ventures milder antitrust scrutiny they find that horizontal research joint ventures lead to more collusion than vertical joint ventures our work provides complementary and more direct evidence since in the laboratory we can observe the level and sustainability of tacit and explicit collusion and can therefore circumvent the measurement and endogeneity issues that are often prevalent in field data the specific research goals of this study are the following first we wish to examine if agents take advantage of available gains from cooperation in the presence of payoff uncertainties that arise from stochastic innovation success second we are interested in learning if a behavioral spillover of cooperation can lead to collusion in markets or whether competition in markets reduces non market cooperation these notions of cooperation concern contributions to joint r d projects or collusion in price setting and are defined independently of any communication opportunities therefore our third goal is to determine how this interaction between cooperation and competition is affected by the introduction of non market communication opportunities finally we will measure the externalities from r d cooperation to non innovators in the market

dynamic r d with spillovers a comment cellini and lambertini 2009 dynamic r d with spillovers competition vs cooperation j econ dyn control 33 568 582 study a dynamic r d game with spillovers this comment demonstrates that contrary to what is claimed in their paper the game is not state redundant and the open loop nash equilibrium is not subgame perfect

antitrust policy towards co operative r d ventures this paper surveys the theoretical literature on r d cartels and the empirical literature on problems of appropriability in order to evaluate the case for encouraging antitrust authorities to treat r d cooperative ventures leniently the case for r d cooperative ventures trades potential gains from internalizing technological spillovers off against a possible reduction in output market competition but the empirical evidence suggests that r d spillovers can easily be exaggerated this suggests that the design of antitrust policy towards r d cooperative ventures is likely to be of major importance if they are to yield net social gains and the paper concludes with a critical examination of the ncra introduced in u s and block exemption introduced in europe in the 1980s copyright 1993 by oxford university press

the impact of r d cooperations and mergers in pharmaceuticals on research activities and drugs offered on the market in the last 10 years the pharmaceutical industry has experienced steep unprecedented price increases which are frequently attributed to increasing drug development costs to cope with rocketing development costs companies engage in research and development r d cooperations we study the impact of r d cooperations on firms research activities and drugs offered on the market using a comprehensive dataset we find that r d cooperations formed at the early stage of the drug development process increase the number of r d projects and the number of drugs offered on the market late stage r d cooperations formed among larger firms in technology and product markets increase firms research activities but reduce the number of drugs launched on the product market results suggest that large firms cooperating in the late research stage re optimize their r d pipelines and eliminate similarly aligned research projects

symmetric research joint ventures cooperative substitutes and complements we introduce the concepts of cooperative substitutes and complements and use them to explain when all firms in a research joint venture will choose equal levels of r d we show that the second order conditions for a symmetric optimum take a particularly simple form ruling out both excessive cooperative substitutability and excessive cooperative complementarity and nesting conditions already derived in the literature finally we apply our results to the comparison between cooperative and non cooperative r d and show in an important special case that asymmetric outcomes are only optimal for a very limited range of parameter values

strategic investment with asymmetric spillovers this paper investigates the implications of asymmetric spillovers on noncooperative strategic investments in a duopoly with quadratic pay offs a unique equilibrium in the announcement of the leader follower role exists in the case where one firm absorbs large spillovers while the other at most is able to receive only small spillovers the leader in this equilibrium is the firm that absorbs the large spillovers other asymmetries in initial costs or efficiency in research and development do not affect this outcome

deposit insurance and regulatory forbearance are caps on insured deposits optimal considerable academic and public policy attention has been focused on the deposit insurance contract and in particular its mispriced deposit insurance premium this has resulted in a burgeoning literature on the optimal pricing of deposit insurance guarantees see merton 1977 1978 pyle 1983 ronn and verma 1986 acharya and dreyfus 1989 and allen and saunders 1993 for examples in addition other authors have studied the ability of uninsured depositors or debtholders to provide market discipline in the form of marketbased risk premia in the absence of explicit risk based insurance premia see for example ellis and flannery 1989 and avery belton and goldberg 1988 however a third control instrument namely the setting of ceilings or caps on the amount of deposit insurance coverage has not been subject to rigorous investigation in particular while the fdic 1989 and others have considered the general pros and cons of limiting the scope of deposit insurance for instance by lowering the 100 000 ceiling on the amount of insurance per account or by restricting the brokering in of deposits l no formal analysis of the role of coverage caps can be

downstream research joint venture with upstream market power in a vertically related industry we examine the downstream firms incentives to invest in cost reducing research and development r d and to form a research joint venture rjv under two alternative structures of input supply exclusive vertical relations and a single supplier in contrast to the hold up argument in which downstream firms invest non cooperatively and spillovers are low r d investments are higher under a single supplier than under competing vertical chains downstream firms incentives to form a rjv are also stronger in the former case than they are in the latter we identify conditions under which an rjv is beneficial for society integrated innovation and competition policies are also discussed

is there anti competitive behaviour in the central canadian cement industry testing arbitrage cost hypotheses allegations of anticompetitive behavior in the central canadian cement industry have focused around the effects of cement producers buying their downstream distributors if indeed vertical integration is causing cement prices to rise the relevant economic theories imply that the arbitrage cost of shipping cement to central canada is greater than the cost of shipping cement from this region the authors investigate this theory by econometrically estimating the relevant arbitrage costs their analysis supports the hypothesis that vertical integration has increased barriers to entry for cement in toronto but it fails to support a similar hypothesis for montreal

r d cooperation and product market competition abstract i derive equilibria that is self enforcing agreements for firms that cooperate in improving their product and compete in marketing it i am particularly interested in the interaction between rd ii product improvement is a function of the effort by each firm iii firms cannot observe each other s effort iv firms market the product by simultaneously setting prices the analysis reveals some surprising results i find that in some cases although monopoly prices can be sustained in equilibrium optimal equilibria call for firms to set lower than monopoly prices in the short run thus providing the right incentives for investment in r d under a different set of assumptions i find that it is optimal to reduce r d effort below the efficient level as a means to sustain short run collusion in prices even though efficient r d effort could be achieved in equilibrium

cross border mergers and strategic alliances this paper develops a model with distribution costs to study firm cooperation in forming strategic alliances and mergers under different types of foreign market entry modes that is export or foreign direct investment fdi under both export and fdi we find that cross border alliances mergers dominate domestic alliances mergers and cross border alliances and mergers are preferred to independence if and only if distribution cost is high under export cross border alliances are chosen in equilibrium if distribution cost is high under fdi and with high distribution cost cross border alliances mergers are chosen in equilibrium if plant setup cost is low high

collusion and research joint ventures i examine the question whether cooperation in r d among firms producing similar products leads to product market collusion suppose that firms engage in a stochastic r d race while maintaining the collusive equilibrium in a repeated game framework innovation under non cooperative r d leads to an inter firm asymmetry destabilizing collusion in pre discovery and post discovery periods innovation sharing under cooperative r d preserves the symmetry and also increases total profit thereby facilitating collusion however welfare may increase with cooperative r d i also examine the condition for collusion under licensing and compare the results

art of the deal the merger settlement process at the federal trade commission 1 introductiontwo firms competing with each other in at least one line of business face a complicated regulatory regime if they attempt to merge under the hart scott rodino hsr act of 1975 almost all large transactions in the united states are subject to review by either the department of justice or the federal trade commission ftc in the event an enforcement agency objects to the transaction several outcomes are possible i the parties could give up and abandon their transaction ii take the case to a federal court and litigate the dispute to a conclusion or iii the firms could settle their differences with the enforcement agency all settlements however are not the same in particular agencies have shown some willingness to accept compromise settlements defined here as consents that do not fully resolve the relevant competitive concerns the purpose of this study is to model the interaction between an antitrust agency and firms seeking to consummate mergers in doing so we will attempt to answer an important question in antitrust regulation what attributes drive the final outcome of a merger challenge this paper will model interactions between the ftc and private parties interested in consummating horizontal mergers that may adversely affect competition in at least one relevant market this decision to fight fold or settle is somewhat more complicated than an action for damages because the prospective nature of the alleged competitive injury gives the defendant an opportunity to abandon the transaction before the injury occurs moreover the conglomerate nature of most mergers creates a possibility for a strong settlement to resolve competitive concerns while allowing the firm to quickly consummate the innocuous portions of the transaction compromise settlements also are possible under which the consent offers partial relief the maximum likelihood estimation procedure used in the paper is derived directly from a game theoretic analysis that models the outcome of the interaction between merging firms and the ftc this allows for formal estimation of utility functions for both merging parties and the ftc estimating the structural equations of the model offers more detailed insight into the regulatory system we have two basic hypotheses with respect to this process first the underlying opportunity costs the legal merits of particular cases and possibly the political ramifications of enforcement decisions drive ftc decisions second firms decisions depend not only on the competitive merits of the ftc s case but perhaps more importantly on both the financial issues relevant to the specific transaction and how the nature of the case fits into the merger review process section 2 presents the background for the analysis by discussing the institutional structure of the ftc explaining the merger review process describing the hostage effects that may affect a firm s response to an ftc enforcement decision and introducing the idea of a compromise settlement section 3 models the game theoretic interaction between firms and the ftc and then explores an econometrically tractable method of estimating the underlying utility functions for the players in the game section 4 describes the data and specifications to be used results of the maximum likelihood estimation are presented in section 5 concluding comments are in section 6 we hope to shed light on an important aspect of the u s merger review process we also suggest that our results may have broader consequences since the mid 1980s a large number of countries have established formal antitrust procedures the results here may be of assistance to those policy regimes as well 2 issues in merger enforcementbackground on the ftcthe ftc is a government agency charged along with the department of justice doj with enforcing u s antitrust laws the bulk of the casework involves the evaluation of proposed horizontal mergers

international r d rivalry and industrial strategy this paper presents a theory of government intervention which provides an explanation for industrial strategy policies such as r d or export subsidies in imperfectly competitive international markets domestic net welfare is improved by the capture of a greater share of the output of rent earning industries although the subsidy ridden noncooperative international equilibrium is jointly suboptimal behaviour of governments and firms is modelled as a three stage subgame perfect nash equilibrium the assumption that the government is the first player in this game allows it to influence equilibrium outcomes by altering the set of credible actions open to firms

default and renegotiation a dynamic model of debt we analyze the role of debt in persuading an entrepreneur to pay out cash e ows rather than to divertthem in the e rstpartof the paper we study the optimal debt contract specie cally the trade off between the size of the loan and the repayment under the assumption that some debt contract is optimal in the second part we consider a more general class of nondebt contracts and derive sufficient conditions for debt to be optimal among these

cooperative and noncooperative r d in duopoly with spillovers erratum in our article published in this review volume 78 no 5 december 1988 pp 1133 37 we have shown that in the presence of sufficient spillovers of the r d benefits duopolists cooperating in r d but not in the output spend more on r d than noncooperating firms at both stages and also produce more output closest to the socially optimal level a second symmetric result is that for small spillovers duopolists cooperating neither in r d nor in output spend more on r d and produce more output than cooperative firms however this result has been obscured by an obvious inequality inversion and other typos implying a modification in the conclusions indeed in fn 13 on p 1135 one should have that x x iff
