follower payoffs in symmetric duopoly games this paper compares the leader and follower payoff in a duopoly game as they arise in sequential play with the nash payoff in simultaneous play if the game is symmetric has a unique symmetric nash equilibrium and players payoffs are monotonic in the opponent s choice along their own best reply function then the follower payoff is either higher than the leader payoff or even lower than in the simultaneous game this gap for the possible follower payoff had not been observed in earlier duopoly models of endogenous timing

strategic behavior in contests comment almost by definition contests involve strategy this is especially true in contests between unevenly matched contenders in a recent article avinash dixit 1987 explored strategic commitment in contests between a favorite and an underdog the favorite is defined as the player whose chance of victory exceeds one half at the nash equilibrium an underdog s chance is less than one half dixit concludes that if the favorite has the opportunity to move first then he will overcommit effort compared with the nash equilibrium an important implication of the favorite overcommitting effort is that strategic behavior leads to greater social costs see gordon tullock 1980 the opposite holds if the underdog has the opportunity to move first this paper demonstrates that the favorite will never overcommit effort given endogenous order of moves the favorite finds it advantageous to wait until the underdog moves surprisingly the underdog s best strategy is not to wait but to make the first move throwing the first punch the equilibrium order of play is for the underdog to move before the favorite in this equilibrium one never observes overcommitment of effort consequently extending dixit s model to allow for endogenous order of moves suggests that strategic behavior in contests will lead to undercommitment compared with nash behavior

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

disaggregating the developing welfare state provincial social policy regimes in china summary local variation in social welfare provision appears in myriad contexts around the world and yet our attempts at conceptualizing welfare regimes focus on the national level in china local authorities have shaped social policy implementation since economic reforms in this paper i answer three questions about subnational variation in social policy provision in china 1 have chinese provinces diverged in their social policy provision 2 how do provincial social policy regimes differ from one another 3 what explains variation in provincial social policy spending to answer the first question i conduct a cluster analysis of provincial social policy spending data i find that provinces systematically diverge in their social policy priorities while some provinces invest in education to develop human capital and promote economic growth others emphasize poverty alleviation i propose a typology to conceptualize these tendencies i then test for these divergent approaches using between effects regression models of provincial social policy spending although provincial wealth and needs sometimes play a role in allocations for social policy i find that economic development strategy and social instability are associated with distinct approaches to social welfare spending these distinct provincial welfare regimes have implications for the adoption implementation and ultimately effectiveness of social policy in china

endogenous timing in games of commercial policy this paper analyzes various equilibria associated with intervention in trade in the context of noncooperative policy games with endogenous timing it is shown that while the subgame perfect equilibria in quota games always involve sequential play that is not necessarily the case in tariff games one implication of the analysis is that in contrast to existing theory trade is not eliminated in quota games another implication is that quotas are not necessarily inferior to tariffs the paper also examines the ways policy leaders and followers differ in their preferences over instruments and allows the choice over instruments to be determined endogenously this paper analyses various equilibria associated with intervention in trade in the context on non cooperative policy games with endogenous timing it is shown that while the subgame perfect equilibria in quota games always involve sequential play that is not necessarily the case in tariff games one implication of the analysis is that in contrast to existing theory trade is not eliminated in quota games another implication is that quotas are not necessarily inferior to tariffs the paper also examines the ways policy leaders and followers differ in their preferences over instruments and allows the choice over instruments to be determined endogenously

second mover disadvantages in a three player stackelberg game with private information abstract i consider a three player stackelberg game where each player has its private signal concerning stochastic demand i show that at a perfectly revealing equilibrium the second mover earns the lowest and the third mover the highest expected profit of the three i characterize this result by the strategic substitutes or complements relationships among three firms at the equilibrium journal of economic literature classification numbers c72 d82 and l13

a theory of interregional tax competition a general equilibrium model is constructed to study tax competition where local governments compete for capital by holding down property tax rates and public expenditure levels an exact definition of tax competition is provided and both the existence and nonexistence of tax competition are shown to be theoretically possible it is argued however that tax competition must occur under empirically reasonable conditions inefficiency in public production is also explicitly modeled the amount of capital used to produce a given level of public service output is shown to be greater than that which is required to minimize costs evaluated at the prices facing private firms

stackelberg versus cournot oligopoly equilibrium abstract we compare an m firm cournot model with a hierarchical stackelberg model where m firms choose outputs sequentially the stackelberg equilibrium price is lower so output and total surplus are higher total profits are lower while the first mover in a stackelberg duopoly earns more than a cournot duopolist this is not necessarily true for m 2 we find a surprisingly simple relation which determines whether cournot profit exceeds the stackelberg leader s finally we consider a game with firms choosing whether to reveal their outputs which includes stackelberg and cournot as possible outcomes the equilibrium is stackelberg

stackelberg and marshall this paper advocates a generalized n firm stackelberg model as a plausible testable alternative description of oligopoly a pure strategy equilibrium must exist for this model the main result is that efficiency obtains in the limit as the scale of each firm is shrunk relative to demand this is demonstrated for the case of u shaped average cost and also for that of natural monopoly copyright 1990 by american economic association

state corroding federalism competition among local governments in a decentralized political system is often thought to discipline lazy or corrupt officials improving public good provision and increasing welfare some scholars note possible distortions due to spillovers or a race to the bottom but suggest that central transfers or regulations can remedy these both arguments take for granted a framework of constitutional order in which the central government can collect taxes allocate transfers and enforce regulations autonomously but what if it can t we show that if central enforcement capacity is endogenous interjurisdictional competition may itself erode the center s ability to channel competition in welfare enhancing directions regional governments may compete for capital by shielding firms from central tax collectors bankruptcy courts or regulators the equilibrium result is weaker central law enforcement and usually lower welfare interjurisdictional competition corrodes the state we illustrate with three examples from russia china and the us of cases in which such competition apparently encouraged subnational politicians to help firms evade central taxes or regulations

choosing tax rates and public expenditure levels using majority rule abstract a sufficient condition is presented for a policy to be a condorcet winner when voters differ only in a single characteristic the condition is that all voters utility gradients with respect to the n different policy dimensions lie in the same plane in r n if the policy is a set of commodity tax rates then the condition is implied by the linearity of voters common engel curves if the policy includes levels of public good provision then the vectors of marginal willingness to pay for the various public goods of the different voters must all lie on the same line

non binding minimum taxes may foster tax competition abstract in a stackelberg framework of capital income taxation it is shown that imposing a minimum tax rate that is lower than all countries equilibrium tax rates in the unconstrained non cooperative equilibrium may reduce equilibrium tax rates in all countries

mixed duopoly privatization and subsidization with excess burden of taxation we investigate optimal tax subsidy policies in mixed and private oligopolies with excess burden of taxation we compare the optimal subsidies and the resulting welfare levels among four regimes mixed and private cournot duopolies and stackelberg competition with public and private leaderships we show that in contrast to the existing works on the privatization neutrality theorem privatization affects resulting welfare duopole mixte privatisation et subsidisation en presence de fardeau fiscal excedentaire on examine les politiques optimales de taxes et de subventions dans le cas d oligopoles mixtes et prives en presence de fardeau fiscal excedentaire on compare les subsides optimaux et les effets sur le niveau de bien etre dans quatre regimes les duopoles de cournot mixte et prive et la concurrence a la stackelberg avec leadership public et prive on montre que contrairement a ce que suggeraient les travaux anterieurs sur le theoreme de la neutralite de la privatisation la privatisation affecte les niveaux de bien etre

stackelberg versus cournot equilibrium we reconsider stackelberg s classical critique of the cournot duopoly in the framework of endogenous timing for two player games for quantity duopoly we provide different sets of minimal conditions directly on the demand and cost functions yielding respectively the simultaneous and the two sequential modes of play while our findings essentially confirm the predominance of the former they also indicate that the latter is natural under some robust but restrictive conditions no extraneous assumptions such as concavity existence or uniqueness of equilibria are needed and the analysis makes crucial use of the basic results from the theory of supermodular games classification numbers b21 c72 d43 l13 c 1999 academic press

pigou tiebout property taxation and the underprovision of local public goods abstract pigou s proposition that the use of distorting taxes rather than neutral head taxes reduces public service levels is examined in this paper a simple model with a national system of competing local governments is utilized to demonstrate that the use of a distorting property tax on mobile capital decreases the level of residential public services the case where public services are an intermediate producer good is also considered

electoral competition globalization and subnational education spending in mexico 1999 2004 this article examines the determinants of primary education spending among 29 mexican states from 1999 to 2004 there is wide variation in spending despite expectations of policy convergence due to market forces associated with globalization and in spite of the unique potential of education spending to complement economic strategies in achieving equitable growth this study exploits significant advantages of subnational analysis in exploring political and economic variables that have been useful in explaining spending levels cross nationally consistent with these studies this article shows that greater electoral competition leads to increased spending in contrast to other work however this study finds that exposure to the global economy has distinctly mixed effects on education spending these findings thus further highlight the positive returns to higher quality democracy while underscoring the need to examine the effects of many different aspects of globalization representing a wide variety of strategies employed by governments in engaging the international economy

endogenous timing in the presence of non monotonicities the aim of this paper is to generalize the endogenous timing game proposed by hamilton and slutsky games and economic behavior 1990 2 pp 29 46 by allowing the payoff or the marginal payoff of a player to become non monotonic with respect to the strategy of the opponent we propose a taxonomy of the subgame perfect nash equilibria based on the characteristics of the payoff functions proposed by eaton canadian journal of economics 2004 37 pp 805 29 we determine under which conditions of the initial payoff functions commitment has a social value and when the simultaneous move nash equilibrium is commitment robust and discuss its pareto efficiency

tariff strategies and small open economies in this paper we examine the issue of optimal tariffs for a small economy that trades with a large economy we define small and large in the sense that the world prices are determined solely by the large country and therefore the small country faces exogenously given world prices within this framework it is shown that there exist situations in which the small country has an incentive to behave as a stackelberg leader by committing itself to a non zero optimal tariff although the small country is unable to directly affect world prices by pre committing to a non zero trade tax it may induce a reduction of the large country s optimal trade tax thereby indirectly improving its terms of trade and welfare jel classification f13 f35

firm scale and the endogenous timing of entry a choice between commitment and flexibility abstract this paper presents a model of stochastic oligopoly with demand uncertainty where firms endogenously choose entry timing we examine two extreme types of market structure and show that the equilibrium correspondence that connects them is continous with two identically sized firms there are symmetric cournot type equilibria where the probability of early entry declines with greater uncertainty and for low uncertainty two asymmetric equilibria with one large firm with a continuum of nonatomic firms there is a unique stackelberg equilibrium we conclude that the behavior of a dominant firm with a finite fringe can be approximated by stackelberg equilibrium journal of economic literatureclassification numbers d21 l11

jeux sans frontieres tax competition and tax coordination when countries differ in size closer international integration is putting increasing pressure on existing national tax structures this paper uses a simple two country model to address a range of consequent policy concerns focusing particularly on the role of country size differences in size exacerbate the inefficiency from noncooperative behavior harming both countries the smaller country loses from harmonization to any tax rate between those set in the noncooperative equilibrium but both countries gain from the imposition of a minimum tax anywhere in that range the fully optimal response to freer cross border trade however may be to do nothing jel h20 h77

federalism chinese style the political basis for economic success in china china s remarkable economic success rests on a foundation of political reform providing a considerable degree of credible commitment to markets this reform reflects a special type of institutionalized decentralization that the authors call federalism chinese style this form of decentralization has three consequences first it fosters competition not only in product markets but also among local governments for labor and foreign capital this competition in turn encourages local government experimentation and learning with new forms of enterprises regulation and economic relationships second it provides incentives for local governments to promote local economic prosperity finally it provides a significant amount of protection to local governments and their enterprises from political intrusion by the central government

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