We conduct a field and an online classroom experiment to study gender differences in self-set performance goals and their effects on performance in a real-effort task. We distinguish between public and private goals, performance being public and identifiable in both cases. Participants set significantly more ambitious goals when these are public. W...

We conduct a laboratory experiment to investigate how different deliberative structures of varying inclusiveness affect collective decisions in the presence of economic conflict. An electorate consists of two groups, one informed and one uninformed about an uncertain state of the economy. This state affects payoffs differently for the two groups. W...

A common rationale for the use of salary contracts is that they can produce substantial incentive effects when coupled with firing threats. However, enforcing firing threats may require close supervision of employees, thus possibly offsetting the very reasons salaries are commonly used, such as lowering monitoring costs and granting autonomy to emp...

We study the performance effects of two profit sharing schemes in a simplified representation of an organization with high task interdependence. The production process involves three stages such that output of earlier stages is the necessary input for subsequent stages. Work at earlier stages is easier than at later stages and the product is only f...

Advice processes are omnipresent in our professional and private lives. We use a laboratory experiment to study how gender and gender matching affect advice giving and how gender matching affects advice following about entry into a real-effort tournament. For advice giving we find that women are less likely than men to recommend tournament entry to...

Competition involves two dimensions, rivalry for resources and social-status ranking. In our experiment we exclude the first dimension and investigate gender differences in the preference for status ranking. Participants perform a task under non-rivalry incentives. Before doing so, individuals indicate whether they prefer to do the task in an envir...

We present results from three-player experiments aimed at studying distributional concerns in how owner-managers compensate themselves and workers of different productivities and effort costs, as well as their relations to various equity principles. We are also interested in how owner-managers decisions’ are affected by pay secrecy. We use a game i...

Competition involves two main dimensions, a rivalry for resources and the ranking of relative performance. If socially recognized, the latter yields a ranking in terms of social status. The rivalry for resources resulting from competitive incentives has been found to negatively affect women’s performance relative to that of men. However, little is...

We study behavior in a simplified representation of an organization with a combination of sequential and pooled task interdependence. The production process involves three stages such that output of earlier stages is the necessary input for subsequent stages. Work at earlier stages is easier than at later stages and the product is only final if it...

We study how communication affects cooperation in an experimental public goods environment with punishment and counter-punishment opportunities. Participants interacted over 30 rounds in fixed groups with fixed identifiers that allowed them to trace other group members' behavior over time. The two dimensions of communication we study are asking for...

We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over—a simple fresh start—leads to an initial increase of cooperation, but to a subsequent new decay. Motivated by cooperation decay in organizations we...

We present experiments studying how high-ability individuals use help to foster efficient coordination. After an initial phase that traps groups in a low-productivity equilibrium, incentives to coordinate are increased, making it possible to escape this performance trap. The design varies whether high-ability individuals can offer help and, if so,...

In many areas of social life, individuals receive information about a particular issue of interest from multiple sources. When these sources are connected through a network, then proper aggregation of this information by an individual involves taking into account the structure of this network. The inability to aggregate properly may lead to various...

We study the effectiveness of leaders for inducing coordinated organizational change to a more efficient equilibrium, i.e., a turnaround. We compare communication from leaders to incentive increases and also compare the effectiveness of randomly selected and elected leaders. Although all interventions yield shifts to more efficient equilibria, comm...

We investigate the nature of continuous time strategic interactions in public-goods games. In one set of treatments, four subjects make contribution decisions in continuous time during a 10-minute interval while in another they make them only at 10 discrete points of time during this interval. The effect of continuous time is muted in public-goods...

We investigate parochial altruism, the combination of in-group altruism and out-group hostility, in an experimental conflict game preceded by a prisoner’s dilemma. Our data are consistent with parochial altruism, but cannot be explained by in-group pro-sociality or out-group hostility alone.

We study experimentally how the ability to communicate affects the frequency and effectiveness of flexible and inflexible contracts in a bilateral trade context where sellers can adjust trade quality after observing a post-contractual cost shock and a discretionary buyer transfer. In the absence of communication, we find that rigid contracts are mo...

We present a brief overview of the experimental economics literature on social preferences. In numerous experiments, economically incentivized subjects are willing to sacrifice part of their material earnings to compensate the kind behavior of others, or will be willing to reciprocate at a non-negligible cost, or even pay a positive price for punis...

In this paper, we present a first survey of the literature regarding whether the strategy method, in which a responder makes conditional decisions for each possible information set, leads to different experimental results than does the more standard direct-response method, in which the responder learns the action of the first mover and then chooses...

We use laboratory experiments to investigate how employers develop social structures for sharing information about the trustworthiness of job candidates, when worker opportunism is possible. The experimental data show that substantial information sharing emerges. Two types of information networks are observed. One consists of 'anonymity networks' w...

We present a comprehensive experimental design that makes it possible to characterize other-regarding preferences and their relationship to the decision maker’s relative position. Participants are faced with a large number of decisions involving variations in the trade-offs between own and other’s payoffs, as well as in other potentially important...

We study how the number of traders affects the interaction between a centralized exchange and bilateral negotiations in an experimental labor market with excess supply and incomplete contracts. Our large markets are three times as large as our small markets. In bilateral negotiations firms obtain information about employees' performance in previous...

This paper studies experimentally how firms choose between using a centralized market and bilateral negotiations to recruit new personnel. In the market firms interact with several workers but do not have information about workers' behavior in the past. In the bilateral negotiations firms negotiate bilaterally with prospective workers and learn abo...

Reinhard Selten’s work marks the beginning of the experimental analysis of oligopoly. Indeed, his research includes both one of the first experiments on quantity competition and the first one on price competition. In the aftermath a very rich literature has emerged, dealing both with theory-based issues linked to the many oligopoly models that appe...

In this paper, we survey the literature regarding whether the strategy method, in which a responder makes conditional decisions for each possible information set, leads to different experimental results than does the more standard direct-response method, in which the responder learns the action of the first mover and then chooses a response. While...

We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of sociopolitical conflict. The theoretical prediction is that conflict expenditures are independent of group size and of whether punishment is available. We find, first, tha...

Bertrand competition under decreasing returns involves a wide interval of pure strategy Nash equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. More firms lead to lower average prices. However, prices remain substantially above the Walrasian level. With m...

We use experiments to study the efficiency effects of adding the possibility of forward contracting to a spot market. We focus on the strategic implications of a forward market and consider both quantity and supply function competition. In both cases we compare the effect of adding a contract market to the introduction of an additional competitor....

We study manager–employee interactions in experiments set in a corporate environment where payoffs depend on employees coordinating at high effort levels; the underlying game being played repeatedly by employees is a weak-link game. In the absence of managerial intervention subjects invariably slip into coordination failure. To overcome a history...

We study how the heterogeneity of agents affects the extent to which changes in financial incentives can pull a group out of a situation of coordination failure. We focus on the connections between cost asymmetries and leadership. Experimental subjects interact in groups of four in a series of weak-link games. The treatment variable is the distribu...

This paper studies experimentally how the existence of social information networks affects the ways in which firms recruit new personnel. Through such networks firms learn about prospective employees' performance in previous jobs. Assuming individualistic preferences social networks are predicted not to affect overall labor market behavior, while w...

We study the process by which subordinated regions of a country can obtain a more favourable political status. In our theoretical model a dominant and a dominated region first interact through a voting process that can lead to different degrees of autonomy. If this process fails then both regions engage in a costly political conflict which can only...

The Dixit (1980) hypothesis that incumbents use investment in capacity to deter potential entrants has found little empirical support. Bagwell and Ramey (1996) propose a model where, in the unique game-theoretic prediction based on forward induction or iterated elimination of weakly-dominated strategies, the incumbent does not have the strategic ad...

We use experimental data to obtain a detailed description of individuals' pro-sociality. Participants are faced with a large number of decisions involving variations in the trade-offs between own and others' payoffs, as well as in other potentially important factors like individuals' positions vis-à-vis others. We find that decisions are affected b...

Motivated by problems of coordination failure in organizations, we examine how overcoming coordination failure and maintaining coordination depend on the ability of individuals to observe others’ choices. Subjects’ payoffs depend on coordinating at high effort levels in a weak-link game. Treatments vary along two dimensions. First, subjects eit...

We study how financial incentives can be used to overcome a history of coordination failure using controlled laboratory experiments. Subjects' payoffs depend on coordinating at high effort levels. In an initial phase, the benefits of coordination are low, and play typically converges to an inefficient outcome. We then explore varying financial ince...

We study the relation between the number of firms and price-cost margins under price competition with uncertainty about competitors' costs. We report an experiment in which two, three, and four identical firms repeatedly interact in this environment. In line with the theoretical prediction, market prices decrease with the number of firms, but on av...

In this chapter we study collusive behavior in experimental duopolies that compete in prices under dynamic demand conditions. In one treatment the demand grows at a constant rate. In the other treatment the demand declines at another constant rate. The rates are chosen so that the evolution of the demand in one case is just the reverse in time than...

Many organizations suffer poor performance because its members fail to coordinate on efficient patterns of behavior. In previous research, we have shown that financial incentives can be used to find a way out of such performance traps. Here we examine the sensitivity of this result to the ability of people to observe others' choices. Our experiment...

We study how two dimensions of market conditions affect behaviour in experimental gift-exchange markets with repeated interaction. First, we consider the impact of competitive imbalance, by varying whether there is an excess supply of "firms" or an excess supply of "workers" in the market. Second, we impose a minimum wage in the market with an exce...

This paper studies behavior in experiments with a linear voluntary contributions mechanism for public goods conducted in Japan, the Netherlands, Spain and the U.S.A. The same experimental design was used in the four countries. Our `contribution function' design allows us to obtain a view of subjects' behavior from two complementary points of view....

We study whether people's behavior in a one-shot sequential public goods type situation is affected by social information about average behavior by others in the same situation. The kind of social information we consider does not directly affect subjects' payoffs and we are, therefore, able to separate pure social influence from more conventional d...

While the theoretical industrial organization literature has long argued that excess capacity can be used to deter entry into markets, there is little empirical evidence that incumbent firms effectively behave in this way. Bagwell and Ramey (1996) propose a game with a specific sequence of moves and partially-recoverable capacity costs in which for...

We study whether behavior in experimental gift-exchange markets with repeated interaction is affected by market conditions. One issue we consider is the impact of competitive imbalance, by varying whether there is an excess supply of firms or an excess supply of workers in the market. Workers might react differently to high wage offers in the two c...

We study experimental multi-unit uniform and discriminatory auctions with demand uncertainty, motivated by the ongoing debate about market design in the electricity industry. We study the effect of asymmetric demand-information in the two auction institutions. In our treatment condition some sellers have less information than in our baseline condit...

This paper presents evidence that the willingness to punish an unfair action is sensitive to whether this action was preceded by a deceptive message. One player first sends a message indicating an intended play, which is either favorable or unfavorable to the other player in the game. After the message, the sender and the receiver play a simultaneo...

The Bank of Spain uses a unique auction format to sell government bonds that can be seen as a hybrid of a uniform and a discriminatory auction. For winning bids above the average winning bid, buyers are charged the average winning bid; otherwise they pay their respective bids. We use experiments to compare this auction format to the discriminatory...

We study the relation between the number of firms and market power in experimental oligopolies. Price competition under decreasing returns involves a wide interval of pure strategy equilibrium prices. We present results of an experiment in which two, three and four identical firms repeatedly interact in this environment. Less collusion with more fi...

We study whether people's behavior in a one-shot sequential public goods type situation is affected by social information about average behavior by others in the same situation. The kind of social information we consider does not directly affect subjects' payoffs and we are, therefore, able to separate pure social influence from more conventional d...

Corruption in the public sector erodes tax compliance and leads to higher tax evasion. Moreover, corrupt public officials abuse their public power to extort bribes from the private agents. In both types of interaction with the public sector, the private agents are bound to face uncertainty with respect to their disposable incomes. To analyse effect...

There is little evidence on unemployment duration and its determinants in developing countries. This study is on the duration aspect of unemployment in a developing country, Turkey. We analyze the determinants of the probability of leaving unemployment for employment or the hazard rate. The effects of the personal and household characteristics and...

We study whether people's preferences in an unbalanced market are affected by whether they are on the excess supply side or the excess demand side of the market. Our analysis is based on the comparison of behavior between two types of experimental gift exchange markets, which vary only with respect to whether first or second movers are on the long...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our “hot” treatment the second player responds to the first player's observed action while in our “cold” treatment we follow the “strategy method” and have the second player decide on a contingent...

Evidence shows that real-effort investments can affect bilateral bargaining outcomes. This paper investigates whether similar investments can inhibit equilibrium convergence of experimental markets. In one treatment, sellers’ relative effort affects the allocation of production costs, but a random productivity shock ensures that the allocation is n...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our “hot†treatment the second player responds to the first player's observed action while in our “cold†treatment we follow the “strategy method†and have the second player decide on a c...

We introduce a new design for experiments with the voluntary contributions mechanism for public goods. Subjects report a complete contribution function in each period, i.e. a contribution level for various marginal rates of transformation between a public and a private good. The results show that subjects’ behavior cannot be explained exclusively a...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our “hot” treatment the second player responds to the first player’s observed action while in our “cold” treatment we follow the “strategy method” and have the second player decide on a contingent...

This paper tests recent models of social preferences using simple exper- imental games based on sequential binary choices. We capture the will- ingness to sacri…ce of each subject with two versions of the same game: a discrete dictator game (to elicit distributional concerns) and a sequential game where they can observe (and reward or punish) the b...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our "hot" treatment the second player responds to the first player's observed action while in our "cold" treatment we follow the "strategy method" and have the second player decide on a contingent...

We study experimentally how the ability to communicate affects the frequency of using flexible and rigid contracts in a bilateral trade context where sellers can adjust trade quality after observing a post-contractual cost shock and a discretionary buyer transfer. In the absence of communication, we find that rigid contracts are more frequent and l...

We study how the process by which leaders are chosen affects their ability to lead an organization. Leaders in our experiments try to shift employee effort from an inefficient equilibrium toward coordination at an efficient outcome. The only instrument they have available is communication with the employees they lead. We compare a treatment in whic...
