war of attrition evidence from a laboratory experiment on market exit i introduction young industries often undergo a process of shakeout gort and klepper 1982 and klepper 1996 attracting excess firms and gradually shedding them over time more mature industries are likewise often forced to contract in the face of recession or product specific negative demand shocks when an overcrowded industry is forced to shrink which firms exit and which ones survive the conventional answer in economics is that overcrowded industries tend to shed inefficient firms and retain efficient ones we might call this survival of the most efficient a process analogous to natural selection that can adaptively improve the efficiency of industries over time nelson and winter 1982 fudenberg and tirole 1986 model firms exit decisions in overcrowded duopoly markets as wars of attrition and show that the intuition of survival of the most efficient has merit even if firms have little information regarding their costs relative to their competitors however the equilibrium of their game is complex involving a solution to a system of differential equations since neither fortune 500 chief executive officers in the naturally occurring markets nor undergraduate participants in laboratory markets deliberately solve differential equations when deciding whether or not to exit a declining market it is an open question as to how well fudenberg and tirole s rational reconstruction of the exit decision corresponds to the facts of how people make such decisions we report the results of a laboratory experiment designed to answer this question nearly 200 subjects in 16 sessions participated in a total of 3 800 wars of attrition based on fudenberg and tirole s model at the beginning of each period subjects were randomly paired and given a private cost draw that usually induced negative net per second payoffs in a shared market and positive net payoffs per second in monopoly subjects then decided in real time whether and when to exit the market never to return monotonic equilibrium strategy functions predict higher cost inefficient participant exit at an earlier time than their lower cost competitor that is the relatively efficient competitor survives in the market we find that fudenberg and tirole s model organizes our data surprisingly well especially considering its complexity we observe exit by the higher cost firm in 76 of cases when differences between the costs faced by firms are substantial the rate of efficient exit rises to nearly 100 the data on exit times are likewise quite close to the point predictions particularly in the crucial higher portion of the cost distribution that generally governs exit times the median deviation from equilibrium exit times falls to zero by the end and on average subjects earn payouts identical to those predicted in equilibrium our design permits tests of two other conjectures in fudenberg and tirole first our data supports fudenberg and tirole s core comparative static prediction that a decrease in the ex ante likelihood of actually being in a war of attrition leads to an increase in the speed of exit 1 second half of our sessions use costs framed as fixed costs suffered while in the market and half use costs framed as opportunity costs earned by exiting the market there is no evidence that this treatment variable affects exit behavior this isomorphism between gains and losses predicted by standard theory stands in stark contrast to evidence from previous individual decision making experiments suggesting asymmetries in how people react to potential losses and potential gains although wars of attrition have an important place in the game theoretic literature there are surprisingly few experimental studies directly relating to them 2 3 bilodeau childs and mestelman 2004 study a three player full information war of attrition framed as a volunteer game and report widespread failure of equilibrium predictions the predicted volunteer in a subgame perfect nash equilibrium only volunteers 41 of the time

investment and competition this paper examines how industry structure affects corporate investment patterns real options theory shows that deferring irreversible investment in the face of uncertainty is valuable theory also shows that the value of waiting to invest falls if investment opportunities are contestable consistent with these theories we find that firms in monopolistic industries exhibit lower investment q sensitivity and are slower to invest than firms in competitive industries however we find that investment q sensitivity and investment speed are highest in oligopolistic industries suggesting that the value of investing strategically can outweigh the value of waiting indeed oligopolistic industries experience less entry and more exit than other industries

on the interplay of informational spillovers and payoff externalities this thesis consists of four independent essays which consider different topics in information economics and political economy the first two papers are variants of the same idea an uninformed principal e g a government will make a decision in order to gain more information it may consult two experts however these experts have a private interest in certain policies being implemented the question is to gain as much information as possible should the principal consult experts who are biased in the same direction or experts who prefer different decisions the main result is that as long as collusion between experts can be prevented homogeneous panels are superior to heterogeneous ones and this advantage increases with the experts informational precision in the third paper two firms consider entry in a new product market and must decide when to enter the market and how to design their product firms do not know for certain what the best design is so both firms want to outwait the other s decision in order to gain more information the focus of the paper is on which firm will make the first decision the main result is that if products are strong strategic substitutes the worst informed firm makes the first decision in equilibrium the analysis should apply to a range of other contexts such as investors trading decisions or the policy choices of political candidates the final paper asks the following question could it be that parties in a two party system may benefit from using several candidates in the same election to promote the use of multiple candidates i assume that a party never runs the risk of having its votes split up among its candidates despite this it turns out that parties have a strong incentive to restrict their number of nominees paradoxically it seems that the more uncertain parties are about voter opinion the fewer candidates they want to use in particular with a uniform voter distribution the optimal number of candidates is one

on the origins of property rights conflict and production in the state of nature i analyse the emergence of property rights in a model of conflict and production in the absence of institutions of enforcement the population of agents evolves dynamically through conflicts for possession of factor goods among pairs of randomly matched agents conflicts are incomplete information wars of attrition with an agent s type consisting of his or her independently drawn valuation of the prize and cost of competing for it i prove equilibrium existence and show that in the steady state of the game the population sorts into two stable groups resource haves and have nots in accordance with a known function of their primitive types

strategic investment under uncertainty a synthesis abstract investment is a central theme in economics finance and operational research traditionally the focus of analysis has been either on assessing the value of flexibility investment under uncertainty or on describing commitment effects in competitive settings industrial organization research contributions addressing the intersection of investment under uncertainty and industrial organization have become numerous in recent years in this paper we provide an overview aimed at categorizing and relating these research streams we highlight managerial insights concerning the nature of competitive advantage first versus second mover advantage the manner in which information is revealed firm heterogeneity capital increment size and the number of competing firms

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

a model of rivalries with endogenous prize and strength abstract this paper extends bevia and corchon 2013 to a model with both endogenous contestable prize and endogenous relative strength such a setting is ideal for the study of intra organizational rivalries commonly observed in family sports promotion and duopoly we find that when the game starts with asymmetric players the weaker player exerts more effort than the stronger player as a result the weaker player partially overcomes the disadvantage of being weak in this setting neither domino nor avalanche effect exists

bridging behavioral and economic theories of decline organizational inertia strategic competition and chronic failure this paper is another plea for bridging behavioral and economic approaches to the study of competition in markets and strategy making by firms the arguments focus on a specific case in point the behavioral theory of organizational decline and the economic modeling of immediate exit the arguments come in three steps first the literature on organizational decline is reviewed by organizing a framework that summarizes arguments from varying economic and organizational perspectives that have for the most part developed independently observations from empirical and theoretical studies are combined in order to investigate the causes conditions courses and consequences of organizational downturn second a theoretical argument is developed that explains voluntary exit and chronic failure by introducing a proxy of organizational inertia in a model of strategic cournot duopoly the key assumptions which have a behavioral flavour that seemingly contradicts orthodox economics are grounded in the theoretical and empirical literatures the results of the model support the claim that pure profit maximizing behavior may be at the expense of organizational survival d aveni 1990 p 135 third by formulating two hypotheses and presenting tentative evidence from the chemical industry the paper hopes to convincingly argue that such integrative models lead to empirical testing of interesting hypotheses a key finding here is that inefficient firms may outlast their efficient rivals cf d aveni 1989a

uncertainty shifting power and appeasement great britain faced an immensely complicated strategic problem in the 1930s and important aspects of it can be stylized as a situation in which a state that is declining in power is unsure of the aims of a rising state if those aims are limited then the declining state prefers to appease the rising state s demands rather than go to war to oppose them if however the rising state s demands are unlimited then the declining state prefers fighting and given that the declining state is becoming weaker over time it prefers fighting sooner rather than later if there is to be a war this situation creates a trade off the earlier a state stands firm the stronger it will be if war ensues but the higher the chance of fighting an unnecessary war in equilibrium the declining state generally tries to appease the rising state by making a series of concessions

the fleeting effect of advertising abstract this paper adds to the evidence that advertising effects depreciate rapidly inclusion of lagged advertising in empirical models may be unnecessary in addition the notion that accumulated advertising effects may be a barrier to entry is called into question

preemption in r d races abstract fudenberg gilbert stiglitz and tirole 1983 consider a patent race in which each firm s instantaneous probability of discovering a patentable invention is an increasing function of its cumulative expenditure on rd in particular we show that for intermediate values of it is possible for the follower to spoil the race by forcing the leader to drop out

exit with multiplant firms using an extension of ghemawat and nalebuff s 1985 model i analyze the outcome of industry decline when firms have multiplant operations the analysis reveals that no natural generalization of their strong empirical prediction that the larger of two single plant duopolists exits first holds in a multiplant setting the results also highlight a number of factors that affect the pattern of capacity removal during industry decline and lead to a discussion of the strategic implications of firms plant size choices in general the factors determining the pattern of capacity reduction can be quite complex and prediction in such settings often requires intimate knowledge of industry structure

child quantity and quality in a developing country family background endogenous tastes and biological supply factors there is a widespread belief that child quality and quantity interact with a tradeoff between the 2 so that one of several important benefits from expanding schooling is that induced fertility reductions will follow the dominant chicago columbia economic model of fertility focuses on this tradeoff the alternative pennsylvania economic analysis of fertility adds to this model by including endogenous tastes and biological supply factors that influence fertility taste norms are posited to be conditioned heavily by childhood family and childhood community background biological supply factors are posited to play a major role in the determination of household fertility for many households excluding those for which the economic and disutility costs of contraceptives are basically 0 the data used in this study are from a cross sectional area stratified random sample of about 4000 women aged 15 45 which were collected in nicaragua in 1977 78 as part of a larger study on the socioeconomic roles of women in developing countries for a subsample of about 500 women sibling data were also collected the study reported in this paper is limited to 252 women who have at least 1 school age child aged 6 13 years and for whom there is at least 1 other sister from the same family also with at least 1 school age child in the sample the empirical estimates basically support the pennsylvania extension of the economic model of fertility beyond the chicago columbia model to incorporate endogenous taste and biological supply factors in the analysis of child quantity and quality determinants in a particular developing country increased female schooling and better labor market alternatives for women may have less impact on fertility in the developing world than some have maintained improvements in health and nutrition in the poorer developing countries may lead to increased fertility through biological supply channels the recent drop in fertility may be due to changing tastes in the determination of child quality the coefficient estimates for mothers schooling are significant in the individual and mean estimates

on industry life cycles delay entry and shakeout in beer brewing abstract this paper proposes a new explanation for industry shakeout an event evident in the life cycle of many industries in which the number of firms drops significantly in a short interval of time based on an in depth analysis of the shakeout in the united states beer brewing industry between 1880 and 1890 we propose that industry shakeouts naturally follow periods of mass entry by firms similar patterns are evident in two other industries we briefly examine the us automobile and tire industries while entry rates fluctuate broadly in all these industries we find that the timing of exit for a given cohort of entrants is remarkably similar over time the exit hazard rate is peaked in the first two years of every cohort s life and drops dramatically to low and stable levels for subsequent ages in this sense mass exit follows mass entry and does not require a deep explanation it is the mass entry evident in the data for these industries that requires an explanation we propose a theoretical model of information accumulation to explain entry into an industry entrepreneurs are uncertain about the profitability of the industry and this uncertainty is resolved through sufficient accumulation of information regarding the fortunes of incumbent firms delay in entry occurs solely due to the fact that it takes time to accumulate sufficient information to support more entry the resulting entry pattern from simulations of the model looks much like that observed in the industries we study

recent advances in oligopoly theory from a game theory perspective abstract this paper surveys the contribution that recent developments in game theory have made to the understanding of oligopoly theory it is argued that conventional models suffer from the problem that there are a number of solution concepts offered with little guidance as to which should be selected and this is related to the static nature of the models employed one important development in game theory has been the analysis of repeated games and when applied to oligopoly theory this suggests that outcomes may be more cooperative than conventional theory suggests related to this is the requirement that firms employ credible threats to punish cheating from cooperative outcomes and the paper examines the extent to which imperfect information may restrict the scope of firms to employ such punishments one way in which firms may seek to make threats credible is through strategic investments for example in production capacity and the paper explores how competition over price or output is integrated with competition over instruments for strategic investment

capital as a commitment strategic investment to deter mobility abstract this paper analyzes how an early entrant in a market can exploit its head start by strategic investment the analysis is based on spence s paper investment strategy and growth in a new market bell j econ 10 1979 1 19 we frist study the investment game in the no discounting case which embodies the key features of mobility deterrence we establish the existence of a set of perfect equilibria and suggest that one particular equilibrium is most reasonable this equilibrium also valid with discounting involves the follower firm being forever deterred from investing to its steady state reaction curve in contrast to spence s proposed solution

a theory of exit in duopoly we develop a duopoly model in which exit occurs because of the existence of fixed costs or opportunity costs each firm enters the market knowing its own cost but not that of its opponent as times goes on each firm becomes increasingly pessimistic about the cost of its remaining rival the time of exit is the only strategic variable so that our model is a war of attrition in contrast to the classic war of attrition however we assume that with positive probability each firm s costs may be low enough that staying in forever is a dominant strategy thus our model unlike the classic one has a unique equilibrium

uniqueness and existence of equilibrium in auctions with a reserve price abstract we prove existence and uniqueness of equilibrium for a general class of two player bidding games we apply our results to the first price auction the combination of first and second price auctions the war of attrition the all pay auction as well as combinations of the latter two auction forms we also treat the first price auction without risk neutrality our results deal with the asymmetric affiliated common values environment in the case where signals are independent our results apply to all equilibria when signals are not independent our uniqueness results hold in the class of nondecreasing strategy equilibria journal of economic literature classification number d44

the sunk cost fallacy in penny auctions this article theoretically and empirically analyses behaviour in penny auctions a relatively new auction mechanism as in the us dollars or war of attrition players in penny auctions commit higher non refundable costs as the auction continues and only win if all other players stop bidding i first show that in any equilibria that does not end immediately players bid probabilistically such that the expected profit from every bid is zero then using two large data sets covering 166 000 auctions i calculate that average profit margins actually exceed 50 to explain this deviation i incorporate a sunk cost fallacy into the theoretical model to generate a set of predictions about hazard rates and player behaviour which i confirm empirically while players do slowly learn to correct this bias and there are few obvious barriers to competition activity in the market is rising and concentration remains relatively high

estimating a war of attrition the case of the us movie theater industry this paper estimates the impact of competition and exogenous demand decline on the exit process of movie theaters in the us from 1950 1965 i modify fudenberg and tirole 1986 s model of exit in a duopoly with incomplete information to an oligopoly i estimate this model with panel data using variations in tv diusion across house holds and other market characteristics to identify the parameters in the theater s payo function and the distribution of unobservable exit values using the estimated model i show that theaters who are making negative pro ts may choose to remain in the market if they expect to outlast their competitors because at that point their pro ts would increase this creates a signi cant delay in the exit process in addition by decompos ing the across market variation in the exit process i nd that tv diusion explains a substantial proportion of the variation in the exit process

the impact of debt financing on entry and exit in a duopoly this article investigates the interaction between market entry company foreclosure and capital structure in a duopoly we find that the order in which firms foreclose is determined not only by differences in firm specific factors but also by common economic factors such as the interest rate and the market profit volatility we extend the exit model by allowing financially distressed firms to renegotiate their debt contracts through a one off debt exchange offer we find that firms with high bankruptcy costs or with prospects of profit improvement can get bigger reductions on their debt repayments investigating market entry we find that financial vulnerability of the incumbent induces earlier entry article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

investment uncertainty and pre emption this paper examines irreversible investment in a project with uncertain returns when there is an advantage to being the first to invest and externalities to investing when others also do so we show that the possibility of pre emption can have significant qualitative and quantitative effects on the relationship between uncertainty and investment in a single agent real options model the trigger threshold for investment increases without bound as uncertainty grows in contrast the investment trigger of a leader faced with pre emption is bounded above as uncertainty increases in fact we show that under certain parameter values greater uncertainty can lead the leader to invest earlier these findings reinforce the importance of extending real options analysis to include strategic interactions between players applications to industry situations are also discussed

real options and preemption under incomplete information abstract this paper introduces incomplete information and preemption into an equilibrium model of firms facing real investment decisions the optimal investment strategy may lie anywhere between the zero npv trigger level and the optimal strategy of a monopolist depending on the distribution of competitors costs and the implied fear of preemption our model implies that the equity returns of firms which hold real options and are subject to preemption will contain jumps and positive skewness

investment timing and learning externalities abstract we study a duopoly model of investment in which each player learns about the quality of a common value project by observing some public background information and possibly the experience of his rival investment costs are private information and the background signal takes the form of a poisson process conditional on the quality of the project being low the resulting attrition game has a unique symmetric equilibrium which depends on initial public beliefs we determine the impact of changes in the cost and signal distributions on investment timing and how equilibrium is affected when a first mover advantage is introduced

sequential correlated equilibria in stopping games in many situations such as trade in stock exchanges agents have many opportunities to act within a short interval of time the agents in such situations can often coordinate their actions in advance but coordination during the game consumes too much time an equilibrium in such situations has to be sequential in order to handle mistakes made by players in this paper we present a new solution concept for infinite horizon dynamic games which is appropriate for such situations a sequential normal form correlated approximate equilibrium under additional assumptions we show that every such game admits this kind of equilibrium

exit in duopoly under uncertainty this paper examines a declining duopoly where the firms must choose when to exit from the market the uncertainty is modeled by letting the revenue stream follow a geometric brownian motion we consider the markovperfect equilibrium in firms exit strategies with a low degree of uncertainty there is a unique equilibrium where one of the fi rms always exits before the other however when uncertainty is increased another equilibrium with the reversed order of exit may appear ruining the uniqueness whether this happens or not depends on the degree of asymmetry in the firm specifi cp arameters

bargaining power strike durations and wage outcomes an analysis of strikes in the 1880s strike outcomes in the 1880s had a winner take all character successful strikes ended with a discrete wage gain failed strikes ended with a return to work at the prestrike wage we present a theoretical interpretation of these outcomes based on a war of attrition model we fit an empirical model specifying the capitulation times of the two parties and the size of the wage gain in the event of a strike success the results show a systematic relation between the determinants of strike success and the determinants of the wage gain for a successful strike

post cartel pricing during litigation standard methods in the u s for calculating antitrust damages in price fixing cases are shown to create a strategic incentive for firms to price above the non collusive price after the cartel has been dissolved this results in an overestimate of the but for price and an underestimate of the level of damages the extent of this upward bias in the but for price is greater the longer the cartel was in place and the more concentrated the industry

war and conflict in economics theories applications and recent trends we review the main economic models of war and conflict these models vary in details but their implications are qualitatively consistent highlighting key commonalities across a variety of conflict settings recent empirical literature employing both laboratory and field data in many cases confirms the basic implications of conflict theory however this literature also presents important challenges to the way economists traditionally model conflict we finish our review by suggesting ways to address these challenges

continuous time games of timing abstract we address the question of existence of equilibrium in general timing games with complete information under weak assumptions any two player timing game has a markov subgame perfect e equilibrium for each e 0 this result is tight for some classes of games symmetric games games with cumulative payoffs stronger existence results are established

when are stabilizations delayed alesina drazen revisited abstract in an influential article alesina and drazen 1991 why are stabilizations delayed american economic review 81 1170 1188 model delay of stabilization as the result of a struggle between political groups supporting reform plans with different distributional implications in this paper we show that ex ante asymmetries in the costs of delay for the groups will reduce the probability of conflict and will lead to a shorter expected delay accurate common information about the cost of delay may lead to no delay at all in an asymmetric conflict a wider divergence in the distributional implications of reform will reduce the probability of conflict but will lead to a longer expected delay we motivate the asymmetric model of delay by reference to latin american episodes of the 1980s

winners and losers in a major price war abstract although retail price wars have received much business press and some research attention it is unclear how they affect consumer purchase behavior this article studies an unprecedented price war in dutch grocery retailing that started in fall 2003 initiated by the market leader to halt its sliding market share the authors investigate the short and long term effects of the price war on store visits on spending and on the sensitivity of these decisions to weekly prices and price image they use a unique data set with consumer hand scan and perceptual data for a national panel of 1821 households covering two years before and two years after the price war started although the price war initially entailed more shopping around and increased spending spending per visit ultimately dropped because consumers redistributed their purchases across stores the price war made consumers more sensitive to weekly prices and price image which helped both the chain that showed an improvement in price image

risk aversion heterogeneity and contests we introduce a novel method of modellingcontests that avoids the complexitiesencountered by the best response function approach we analyse contests in which i there are many risk averse players ii attitudes to risk may differ acrossindividuals and iii the technology thattransforms rent seeking effort intoprobability of winning may also differacross individuals we establish that ifevery player has a constant degree ofabsolute risk aversion a uniqueequilibrium exists we also establishcomparative static results and examine howthe level of rent dissipation is affectedby the heterogeneity of attitudes towardsrisk and the precise nature of the technology

preemption games with private information preemption games are widely used to model economic problems such as patent races we introduce private information into these games and allow for this information to stochastically change over time this reflects e g how r d competitors improve their innovations over time and keep these innovations secret before patenting them the analysis initially appears intractable because of the complexity of the equilibrium updating of beliefs on opponents information however we demonstrate the existence of a class of equilibria and calculate these equilibria in closed form we find that the expected durations in these equilibria are longer than when players information is public but in some cases shorter than in the collusive outcome hence r d secrecy slows down innovation disclosure

capacity choice under uncertainty in a duopoly with endogenous exit abstract applying the real options framework this article investigates the investment decision of the entrant given that an incumbent is already active both firms have an option to exit this market if the demand level falls too low the combination of three decision components capacity choice entry and exit timing results into multiple trigger strategies for the entrant in particular in the presence of a large incumbent it can either choose to coexist with its rival in a duopoly or eventually monopolize the market by installing a sufficiently large capacity the former scenario is realized when the market is large while the latter occurs when the market is small when the market is of intermediate size a hysteresis region emerges where the entrant does not take any actions and prefers to postpone investment

working capital and fixed investment new evidence on financing constraints this article presents new tests for finance constraints on investment by emphasizing the often neglected role of working capital as both a use and a source of funds the coefficient of endogenous working capital investment is negative in a fixed investment regression as expected if working capital competes with fixed investment for a limited pool of finance this finding addresses a criticism of previous research on finance constraints that cash flows may simply proxy shifts in investment demand in addition previous studies may have underestimated the impact of finance constraints on growth and investment because firms smooth fixed investment in the short run with working capital

a signal jamming theory of predation we propose a new theory ofpredation based on signal jamming in our model the predator s characteristics are common knowledge while the entrant is uncertain of his own future profitability the entrant uses his current profit to decide whether to remain in the market and the predator preys to jam or interfere with this inference problem thus our model differs from those based on reputation effects in which the predator preys to signal information about himself

the generalized war of attrition abstract we model a war of attrition with n k firms competing for n prizes in a natural oligopoly context the k 1 lowest value firms drop out instantaneously even though each firm s value is private information to itself in a standard setting context in which every competitor suffers losses until a standard is chosen even after giving up on its own preferred alternative each firm s exit time is independent both of k and of other players actions our results explain how long it takes to form a winning coalition in politics solving the model is facilitated by the revenue equivalence theorem jel d43 d44 l13 o30

developing real option game models by mixing concepts from both game theoretic analysis and real options theory an investment decision in a competitive market can be seen as a game between firms as firms implicitly take into account other firms reactions to their own investment actions we review two decades of real option game models suggesting which critical problems have been solved by considering game theory and which significant problems have not been yet adequately addressed we provide some insights on the plausible empirical applications or shortfalls in applications to date and suggest some promising avenues for future research

the devolution of declining industries in declining industries capacity must be reduced in order to restore profitability who bears this burden where production is all or nothing there is a unique subgame perfect equilibrium the largest firms exit first ghemawat and nalebuff 1985 in this paper firms continuously adjust capacity again there is a unique subgame perfect equilibrium all else equal large firms reduce capacity first and continue to do so until they shrink to the size of their formerly smaller rivals intuitively bigger firms have lower marginal revenue and correspondingly greater incentives to reduce capacity this prediction is supported by empirical findings

preemption games under levy uncertainty abstract we study a stochastic version of fudenberg tirole s preemption game two firms contemplate entering a new market with stochastic demand firms differ in sunk costs of entry if the demand process has no upward jumps the low cost firm enters first and the high cost firm follows if leader s optimization problem has an interior solution the leader enters at the optimal threshold of a monopolist otherwise the leader enters earlier than the monopolist if the demand admits positive jumps then the optimal entry threshold of the leader can be lower than the monopolist s threshold even if the solution is interior simultaneous entry can happen either as an equilibrium or a coordination failure the high cost firm can become the leader we characterize subgame perfect equilibrium strategies in terms of stopping times and value functions analytical expressions for the value functions and thresholds that define stopping times are derived

the determinants of exit in an open economy in this paper the determinants of exit are investigated for the manufacturing sector of the united states economy which has been subjected to growing international influences the analysis uses united states cross sectional data the results of the exit equation suggest that low profitability declining industry growth and displacement of incumbents by entrants foster exit international influences are also seen to have an impact on u s manufacturing exit specifically imports into an industry have a small effect on exit and protection has little influence in stemming exit

reputation and hegemonic stability a game theoretic analysis we develop and explicate a game theoretic model in which repeated play incomplete information and reputation are major elements a significant advance of this model is the way it represents cooperation under incomplete information among rational actors of different sizes the model is used to formalize certain aspects of the theory of hegemonic stability it shows that the dilemma or limits of hegemonic stability look like natural attributes of games where reputation is involved unifying both benevolent and coercive strands of hegemony theory an example drawn from recent developments in the organization of petroleum exporting countries shows how our model of reputation guides the study of hegemonic regime construction we conclude by comparing the nature of cooperative behavior under conditions of complete and incomplete information

a dynamic model of entry and exit in a growing industry the potential demand in a new industry evolves over time demand is initially low but advertising by the industry s early entrants can speed up demand growth however there is intrinsic uncertainty of the demand level in each period and uncertainty of the demand evolution path which can be affected by the underlying economic environment we construct a dynamic model that features the stochastically and endogenously expanding demand of a new industry and we investigate the optimal entry and exit behavior of firms as the industry evolves we find that firms incentive to enter early depends critically on the cost that early entrants have to pay in developing the market when the cost is high and the benefit spills over to potential entrants firms have an incentive to wait and the probability of entry can increase with the number of incumbents under certain circumstances firms entry strategy is also influenced by the transition of economic states firms are more likely to enter under a state that shows the prospect of demand taking off soon we also find that in the early stage of an industry higher demand uncertainty can induce faster entry

gambling in contests this paper presents a strategic model of risk taking behavior in contests formally we analyze an n player winner take all contest in which each player decides when to stop a privately observed brownian motion with drift a player whose process reaches zero has to stop the player with the highest stopping point wins unlike the explicit cost for a higher stopping time in a war of attrition here higher stopping times are riskier because players can go bankrupt we derive a closed form solution of a nash equilibrium outcome in equilibrium highest expected losses occur at an intermediate negative value of the drift

debt and creative destruction why could subsidizing corporate debt be optimal the existing theoretical literature provides little justification for a corporate debt subsidy we illustrate the welfare benefit of this subsidy and study how the social costs and benefits change with the duration of industry distress in our model two firms engage in socially wasteful competition for survival in a declining industry firms differ on two dimensions exogenous productivity and endogenously chosen amount of debt financing resulting in a two dimensional war of attrition debt financing increases incentives to exit which although costly for the firm is socially beneficial these benefits decline as industry distress shortens our normative model sheds light on why the debt tax subsidy still persists around the world analogously the model can also rationalize a seemingly ad hoc feature of the u s tax system which subsidizes the conflict of interest between debt and equity regarding firm liquidation this paper was accepted by amit seru finance
