We report the results of duopoly market experiments where firms first commit to capacities and then compete in prices. The theoretical literature pertaining to these duopoly models suggests that the way residual demand is rationed is fundamental to the character of equilibrium outcomes when capacity costs are sufficiently low. The experiments test this prediction by varying capacity cost and demand‐rationing schemes. We find that residual demand rationing does not significantly impact the capacity choices of experimental subjects, although it does affect pricing. Regardless of rationing scheme, the Cournot outcome is common with high capacity costs and rare with low capacity costs. 相似文献

A “collusion puzzle” exists by which, even though increasing the number of firms reduces the ability to tacitly collude, and leads to a collapse in collusion in experimental markets with three or more firms, in natural markets there are such numbers of firms colluding successfully. We present an experiment showing that, if managers are deferential toward an authority, firms can induce more collusion by delegating production decisions to middle managers and providing suitable informal nudges. This holds not only with two but also with four firms. We are also able to distinguish compliance effects from coordination effects. 相似文献

This article uses computational methods that reveal substantive differences among the equilibrium outcomes from three models of procurement competition: a recently developed model requiring numerical solution and two analytically tractable models that might naturally be considered suitable proxies. The models differ in what sellers know about the buyer's preferences for their products, and they yield substantially different prices and payoffs, different implications for institutional choice, surprising intensities of competition, and qualitatively different comparative statics. These findings caution against using the analytically convenient models when the newer model is empirically appropriate. Reinterpreting the models and results also provides new insights regarding price discrimination in oligopoly. 相似文献

We study tacit collusion in price‐setting duopoly games with strategic complements and substitutes. While this problem has been considered by several studies, this article sheds new light on the comparison by focusing on the relationship between dynamic stability of equilibrium and tacit collusion. We find when controlling for the absolute slope of the reaction functions, there are no robust differences in either the convergence properties or tacit collusion between complements and substitutes treatments. 相似文献

This article proposes a Cournot model of two‐stage competition to examine the patterns of vertical product differentiation in a multiproduct duopoly. Firms simultaneously choose the number of products and their qualities at the first stage and compete in quantities at the second stage. We show that when the fixed setup cost of a product is high enough to result in a monopoly outcome, the monopolist always sells a single product. Moreover, in any equilibrium of a multiproduct duopoly, quality differentiation between them will develop into a nonsegmented pattern because each firm desires to avoid a strong effect of cannibalization. The set of equilibria reveals the properties of quality differentiation between multiproduct firms. In a multiproduct duopoly, the profit from a high‐quality product can be lower than that from a low‐quality product. This finding sharply contrasts with the literature on single‐product firms, which finds the high‐quality advantage. 相似文献

We study the effect of communication in an experimental game where cooperation is consistent with equilibrium play. We examine two methodological questions which affect many studies of communication in games, particularly those studying the relationship between communication and cooperation in supergames. We show that making it easier for subjects to reach an agreement (by allowing more rounds of communication) does not increase cooperation with a limited message space treatment. Thus, limited message space treatments are not a good substitute for the use of chat. Making the game longer, thereby making the connection between the first period and the continuation game more obvious, also has little impact on cooperation. For both the two‐ and three‐period versions of our game we find substantial amounts of contingent play. This implies that use of a finitely repeated game, which has a number of methodological advantages, maintains the main properties of the underlying supergame. 相似文献

We use experiments to analyze multiple dimensions of the relationship between rank incentives and individual performance. In our experiment (i) rank is defined as subjects' relative position in their group based on their performance in a real effort task and (ii) subjects' earnings are independent of their performance. We find that any rank incentive improves mean performance than no rank incentive, and this result is independent of the group size. In the large group, the mean performance increases strictly in all except at the highest rank incentive, but in the small group the mean performance increases weakly in rank incentives. Finally, the mean performance is significantly higher in the large than in the small group because of a higher “prestige effect.” In additional treatments in which we do not reveal the identity of the status‐prize winners, we find that average performance is identical to that in the baseline treatment without any status prizes. The last result signifies the important role that public revelation plays to enhance the strength of status. The results are important for managerial practices. 相似文献

The observed increase in the level and volatility of Tanzania's Treasury yields in recent years against an otherwise benign macroeconomic backdrop presented a puzzle for policymakers, while raising concerns about the fiscal burden of rising debt interest payments and diversion of bank credit away from the private sector. Using evidence from bid-level data, and supported by a simple theorising of bidder incentives under unorthodox issuance practices, this paper traces the recent volatility in yields to the emergence of a sharp segmentation of the T-bill market between sophisticated financial market players (foreign-controlled banks) and a less-experienced group of investors (domestic pension funds and small banks). An important policy recommendation that emerges is that public debt managers should avoid micro-managing Treasury bill auctions by issuing amounts in excess of those offered or by dipping into oversubscribed segments of the yield curve, as such practices seriously disadvantage the less-sophisticated (but more competitive) investors vis-à-vis the more sophisticated players. 相似文献

This article analyzes endogenous efficiency gains from mergers. It considers oligopolistic homogeneous good markets and duopolistic and triopolistic markets under product differentiation (PD) (quantity and price competition). In a two‐stage game, firms invest in cost‐reducing innovation (with and without mergers) and then compete in output/prices. It is found that in homogeneous good markets, all possible mergers generate efficiency gains, and that these are most significant when R&D spillovers are very low or very high. Efficiency gains increase with the number of insiders and generally decrease with the number of outsiders. With PD, in most cases, the merger generates efficiency gains when spillovers and/or PD are sufficiently high. With PD, efficiency gains increase with spillovers, but may increase or decrease with the level of PD. The implications of the results for the relationship between competition and innovation outputs and for merger policy are discussed. 相似文献

Using a model of sequential search, we show that announcements to price‐match raise prices by altering consumer search behavior. First, price‐matching diminishes firms’ incentives to lower prices to attract consumers who have no search costs. Second, for consumers with positive search costs, price‐matching lowers the marginal benefit of search, inducing them to accept higher prices. Finally, price‐matching can lead to asymmetric equilibria where one firm runs fewer sales and both firms tend to offer smaller discounts than in a symmetric equilibrium. Price increases grow in the proportion of consumers who invoke price‐matching guarantees and in the level of equilibrium asymmetry. 相似文献

We provide lab data from four different games that allow us to study whether people have accurate expectations regarding monetary sanctions (punishment/reward) and nonmonetary sanctions (disapproval/approval). Although the strength of the sanction is always predicted with some error (particularly in the case of monetary sanctions), we observe that (i) most subjects anticipate correctly the sign of the average sanction, (ii) expectations covary with sanctions, (iii) the average expectation is very often not significantly different than the average actual sanction, and (iv) the errors exhibit no systematic bias, except in those situations where rewards are frequent. In this line, we find some evidence that punishment is better anticipated than rewards. 相似文献

There are many assignment processes in which agents are given the opportunity to unilaterally select a match. Resulting allocations can be inefficient if agents do not internalize the consequences of their choice on others. To test this formally, we study how other-regarding behaviors vary across two decision contexts: when subjects make a pure allocation decision; and when they select a partner. In both settings each subject's decision is final and it affects their payoff and that of other subjects in the same way. We find that subjects are more likely to sacrifice their own material well-being to increase that of others when dividing a pie than when selecting a partner in a large anonymous setting—even though the consequences on the material payoffs of others are identical. These findings suggest that in assignment processes with unilateral selection, efficiency can be improved by presenting the selection process as a choice between outcomes involving multiple individuals, instead of simply selecting a match for themselves. 相似文献

In the present paper, we propose an extension of Spengler's (1950) analysis of successive oligopolies, to study the effects of entry in the downstream and upstream markets. Free entry is analyzed using replica economies à la Debreu and Scarf (1963) . We find that free entry may have different effects in the upstream and in the downstream market. Namely, the usual convergence of the price to the corresponding marginal cost only occurs in the downstream market. 相似文献

Trophy. Goal. Dominated . Does priming individuals with competitive concepts such as these influence the temptation to cheat? We utilize a standard laboratory cheating task in a tournament setting and test whether nonconscious priming impacts the nature of cheating behavior. The results demonstrate an asymmetry in a winner‐take‐all setting: a competitive prime does not increase cheating to improve one's own outcome, but does significantly increase the willingness of an individual to sabotage a competitor. 相似文献

Competition among individuals comes in a variety of forms: for mates, for resources, and for prestige and recognition. Such competitive pressure can lead individuals to engage in unethical behavior in an effort to get ahead. There are several forms of cheating in which individuals may engage to improve their own outcome: they may lie about their own performance in a task and they may lie about others’ performance in a task. Our research is the first to examine how competition affects each of these two types of cheating behavior. We find that individuals are much more willing to cheat by lying about themselves than they are willing to sabotage another when under competitive pressure. 相似文献

We reinvestigate the question first posed by Glaeser et al. (2000): Do survey measures about trust predict actual trusting behavior? This important study established that the behavior in an incentivized trust game is not correlated with the responses to the most widely used survey measures of trust. We conduct a replication and a reinvestigation of GLSS. In the replication, we use the GLSS protocol and we reproduce their results. In the reinvestigation, we introduce one major change: We replace their variation of the standard Berg, Dickhaut, and McCabe (1995) investment game with the original unmodified game. The standard game endows both players, while the modified version endows only the first mover. After endowing both movers in the reinvestigation experiment, we find a significant correlation between the two measures, suggesting that trust is a single construct, whether measured by the survey questions or by an incentivized trust game. 相似文献

Policymakers are increasingly using whistle-blowing incentives aimed at curtailing illegal or unethical behavior. We theoretically and experimentally investigate one version of whistle-blowing incentive: leniency programs aimed at curbing anticompetitive activities by firms, by reducing the punishment faced by a cartel member who reports the cartel's behavior. The theoretical model captures the two important effects of whistle-blowing incentives: the direct effect, a reduction in the stability of cartels, and the counterproductive indirect effect, an increase in the incentives to form cartels in the first place by lowering the cost of exiting them. As these point in opposite directions, the net theoretical effect is indeterminate. Our laboratory experiment compares two leniency programs—full immunity from fines and partial immunity—against a baseline with no whistle-blowing incentives in place. We find evidence of the direct effect but not the indirect effect, and thus both programs reduce the extent of price fixing and the damage associated with it. 相似文献

We revisit the claims about the biological underpinnings of economic behavior by specifically exploring if observed gender differences in risk/time preferences can be explained by natural fluctuations in progesterone/estradiol levels during the menstrual cycle and by prenatal exposure to testosterone and estrogen levels. We find no effect of the menstrual cycle (and thereby, of associated fluctuations in progesterone and estradiol levels) or of the digit ratio on either risk or time preferences. 相似文献

In this paper we reconsider existence of Bertrand equilibrium in a symmetric‐cost, homogenous‐product oligopoly. We prove the following main results. (a) If the cost function is strictly superadditive on [0, ∞) then there exists a pure strategy Bertrand equilibrium. Such Bertrand equilibria are necessarily non‐unique. (b) If the cost function is strictly subadditive on [0, ∞) then there exists no Bertrand equilibrium, either in pure strategies or in mixed strategies. 相似文献
