Cooperation limitations under a one-time threat of expulsion and punishment
We examine the role one-time threats of expulsion and punishment have on voluntary contributions in a public goods game. This paper extends the work of Cinyabuguma, Page, and Putterman (2005), who find that the threat of expulsion in every period raises contributions to near Pareto Optimal levels. In our experiments, participants played in 15-round sessions where they were allowed to vote to remove other subjects only after round 5 and in one design also voted whether to punish the remaining subjects after round 10. We find that the additional threat of punishment not only increased the contributions of participants before the punishment vote, but also resulted in the expulsion of participants who had contributed more than in the no punishment treatment. Efficiency with expulsion is 58.07% without punishment, and 57.13% with punishment, including the cost for voting and punishment. Our findings indicate that the threat of expulsion as a sanctioning mechanism may not be helpful for public good provision unless expulsion can occur in every period, the threat of costly punishment increases contributions with little impact on efficiency, and that standards for inclusion rise when later punishment is available.
Mergers with Quality Differentiated Products
We consider the impact of merger on the equilibrium price and quality of products. Consumer demand for both products depends not only on own price and quality, but also on the price and quality of the other product. We consider both the case in which the merging firms produce gross complements, and the case in which the firms produce gross substitutes. In both cases, merger may lower or increase both product price and quality. In the case in which firms produce complementary products, it may happen that firms both lower price and increase product quality when merged. This happens when the cross quality elasticities of demand and the cross price elasticities of demand are equal in magnitude. Surprisingly, we also find that there are situations under which merger between firms producing substitutes increases welfare. For example, it is possible that merger between firms producing gross complements may result in higher product quality but lower social welfare, and merger between firms producing substitute products may result in lower product quality but higher social welfare.
Social Position and Distributive Justice: Experimental Evidence
Using a simple, double-blind dictator experiment, we examine the extent to which subjects\u27 choices of distributive shares are influenced by unearned social position. We measure social position by the initial distributive shares (resources) and the subjects\u27 ability to determine the final distributive shares (power). We find that subjects\u27 decisions are consistent with Rawls\u27 (1971) hypothesis that individuals expect a greater share when in a position with more power and initial resources. Finally, we test if subjects\u27 choices under a laboratory veil of ignorance are consistent with Rawls\u27 concept of distributive justice. Veiled individuals exhibit preferences that are less risk-averse and have greater variance than Rawls hypothesized. [excerpt
An Experimental Study of the Holdout Problem in a Multilateral Bargaining Game
When an economic exchange requires agreement by multiple independent parties, the potential exists for an individual to strategically delay agreement in an attempt to capture a greater share of the surplus created by the exchange. This holdout problem is a common feature of the land-assembly literature because development frequently requires the assembly of multiple parcels of land. We use experimental methods to examine holdout behavior in a laboratory bargaining game that involves multi-person groups, complementary exchanges, and holdout externalities. The results of six treatments that vary the bargaining institution, number of bargaining periods, and cost of delay demonstrate that holdout is common across institutions and is, on average, a payoff-improving strategy for responders. Both proposers and responders take a more aggressive initial bargaining stance in multi-period bargaining treatments relative to single-period treatments, but take a less aggressive bargaining stance when delay is costly. Nearly all exchanges eventually occur in our multi-period treatments, leading to higher overall efficiency relative to the single-period treatments, both with and without delay costs. [excerpt
Multi-Period Rent-Seeking Contests with Carryover: Theory and Experimental Evidence
The majority of theoretical and experimental research stemming from Tullock’s (1980) model of rent-seeking considers static, single-period contests. This paper contributes to a growing body of research on multi-period rent-seeking contests by developing and experimentally testing a model in which a player’s effort affects the probability of winning a contest in both the current and future periods. Theory predicts that rent-seeking effort will be shifted forward from later to earlier periods, with no change in overall rent-seeking expenditures relative to the static contest. Experimental results indicate a significant shift forward when “carryover” is present and that the amount shifted is directly related to the carryover rate. Finally, although experimental expenditures are greater than the equilibrium predictions, overall rent-seeking effort in the carryover contests is lower than in similar static contests.
Contracts, Behavior, and the Land-Assembly Problem:An Experimental Study
We use multilateral bargaining experiments to examine how the order of bargaining (simultaneous or sequential) and the nature of contracts (contingent or non-contingent) affect the duration of bargaining, the efficiency of exchange, and the distribution of the surplus in a laboratory land-assembly game with one buyer and two sellers. While theory predicts an earnings advantage for the first seller when contracts are sequential and contingent, and for the second seller when contracts are sequential and non-contingent, we find that when a seller has an earnings advantage in the laboratory, it is the first seller to bargain in the non-contingent contract treatments. This result contradicts conventional wisdom and a common result from the land-assembly literature that it is advantageous to be the last seller to bargain, a so-called “holdout”. We also find evidence that sequential bargaining leads to more aggressive seller bargaining and greater bargaining delay than simultaneous bargaining, ceteris paribus, and that non-contingent contracts increase bargaining delay and the likelihood of failed agreements. The majority of sellers indicated a preference for being the first seller to bargain in all sequential bargaining treatments.
Personality Preferences and Pre-Commitment: Behavioral Explanations in Ultimatum Games
This paper uses responder pre-commitment and the Jungian theory of mental activity and psychological type, as measured by the widely-used Myers-Briggs Type Indicator (MBTI), to gain insight into subject behavior in a laboratory ultimatum bargaining experiment. Three experiment design details are noteworthy: (1) one design requires responders to make a nonbinding pre-commitment rejection level prior to seeing the offer, (2) one design requires responders to make a binding pre-commitment rejection level, and (3) one design includes a third person (or “hostage”) who makes no decision, but whose payment depends on the proposal being accepted. In general, we find behavior in our experiment to be consistent with hypotheses based on theoretical underpinnings of the MBTI and its descriptions of psychological type.

A Behavioral Model of Multilateral Bargaining and Holdout: Theory with Experimental Evidence
Bilateral monopoly, land assembly, and unanimous-consent Coasian bargaining present interesting strategic questions because they involve division of an economic surplus without competition to temper bargaining demands. We present a behavioral bargaining model in which payoff-maximizing proposers make offers to divide a surplus with one or more responders who are assumed to behave either strategically, or sincerely according to a minimum acceptable offer rule. We characterize equilibrium proposer and responder decisions under various scenarios regarding the number and type of responders, the number of bargaining periods, and the cost of delay. The model predictions are consistent with data from laboratory experiments.
An Experimental Dynamic Public Goods Game with Carryover
We examine voluntary contributions in a two-stage public good experiment with ‘carryover.’ In two treatments, each subject’s second stage endowment is determined by the return from the public good in the first stage. We manipulate payoffs across these treatments so that, relative to our no-carryover baseline, earnings from either Nash play or Pareto Optimal play are held constant. The remaining two treatments maintain a constant endowment in each stage, but vary the marginal per capita return (MPCR) to contributions in the second stage. Our results indicate that carryover increases first stage contributions. Our implementation of carryover enables us to examine the effects of changing endowments and MPCR’s with a wider variety of parameter values than in the existing literature. Consistent with these studies, we find that MPCR and endowment effects are important determinants of subject contributions to the group account. While stage 1 contributions tend to increase in the presence of carryover, efficiency levels across both stages fall relative to the baseline due to the high potential payoffs from complete contribution in the second stage (due to higher endowments or MPCR levels).
