In an experiment on a subjective claims problem we compare three unanimity bargaining procedures - the Demand, the Offer and the Exit variant - in terms of fairness and efficiency. To assess the fairness of the allocations obtained by these procedures, we evaluate them from a partial point of...

In a subjective claims problem several agents have contributed to the production of a cake which is to be divided among them. Since contributions are difficult to compare and the production function is nonlinear, agents'subjective evaluations of claims are likely to be conflicting. In a...

This paper studies a two-sided incomplete information bargaining model between a seller and a buyer. The buyer has an outside option, which is modeled as a sequential search process during which he can also choose to return to bargaining at any time. Two cases considered: In Regime I, both...

This experimental study investigates two bargaining games with twosided incomplete information between a seller and a buyer. In the first game with no outside options many subjects do not use the incomplete information to their advantage as predicted. We find that a model with adjusting priors...

This paper studies the vulnerability of the pivotal mechanism with respect to manipulation by groups. In a lab experiment, groups decide on the implementation of various alternatives, some of which imply opposite interests for the two subgroups. We investigate the occurrence of tacit and...

In division problems with entitlements, we investigate whether fairness concerns overrule strategic behavior and inhibit full use of the decision-making power. In a lab experiment where entitlements are derived from costly contributions, we vary bargaining power by using either the majority rule...

In markets for credence goods - such as health care or repair services - fraudulent behavior by better informed experts is a common problem. Our model studies how four common features shape experts' provision behavior in credence goods markets: (i) diagnostic uncertainty of experts; (ii)...

Credence goods markets are prone to fraudulent behavior and market inefficiencies due to informational asymmetries between sellers and customers. We examine experimentally the effects of diagnostic uncertainty and insurance coverage on the information acquisition and provision decisions by...

Evidence on behavior of experts in credence goods markets raises an important causality issue: Do "fair prices" induce "good behavior", or do "good experts" post "fair prices"? To answer this question we propose and test a model with three seller types: "the good" choose fair prices and behave...

This paper studies the incentives for credence goods experts to invest effort in diagnosis if effort is both costly and unobservable, and if they face competition by discounters who are not able to perform a diagnosis. The unobservability of diagnosis effort and the credence characteristic of...
