Two-Stage Team Rent-Seeking: Experimental Analysis
This paper presents a two-stage team rent-seeking model with a contest prize that is not excludable among winning team members. When early effort is a perfect substitute for late effort, early actors can free ride on their late-moving teammates. However, when early and late efforts are complements, all team members exert positive effort levels. Asymmetries in early effort reduce effort choices for all late movers. The theory is tested with laboratory experimental methods. Although subjects overinvest relative to the Nash equilibrium in all treatments, chosen effort levels provide limited support for the model. Early movers exerted higher effort in the complement treatment, and second-stage effort choices were broadly consistent with best response functions. Surprisingly, in both single-shot and repeated play environments, early movers in the substitute treatment did not free ride, choosing effort levels similar to those of late movers. [excerpt
Endowment Effects and Contribution Strategies in Public Good Experiments
We investigate behavior in a laboratory public good experiment with unique endowment schemes that allow a wider range of contribution strategies than in standard voluntary contribution mechanism (VCM) experiments. A baseline treatment follows a standard VCM design (subjects receive 10 tokens in each of 10 rounds that may be allocated between a private account and a group account). In a new carry-over treatment, any tokens not allocated to the group account in the current period are made available for contributions in future periods. Under full endowment, subjects receive 100 tokens in round one (rather than 10 tokens per round for each of 10 rounds). In the pledge treatment, subjects’ allocation decisions for an initial endowment of 100 tokens may be changed in any round and are binding only for the final round. We find that the size of the effective endowment and whether contributions are binding significantly impact subject decision making. Deviations from the free riding outcome are greater when subjects have a larger portion of their total endowment earlier in the experiment, and subjects contribute less when their contribution decisions are bindin
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).
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
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.
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.

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.
