Under common law, the standard remedy for breach of contract is expectation damages. Under continental law, the standard is specific performance. The common law solution is ex post efficient. But is it also ex ante efficient? We use experimental methods to test whether knowing that...

The Coase theorem posits: If [1] property rights are perfect, [2] contracts are enforceable, [3] preferences are common knowledge, and [4] transaction costs are zero, then the initial allocation of property rights only matters for distribution, not for efficiency. In this paper we claim that...

Public goods are dealt with in two literatures that neglect each other. Mechanism design advises a social planner that expects individuals to misrepresent their valuations. Experiments study the provision of the good when preferences might be non-standard. We introduce the problem of the...

This paper introduces a virtually efficient mechanism in a setting with sequentially arriving agents who hold informative signals about future types. To reveal the information the principal organises betting on future type reports. An agent's betting reward depends on how accurately the prior...

This paper studies the design of optimal utilitarian mechanisms for an excludable public good. Excludability provides a basis for making people pay for admissions; the payments can be used for redistribution and/or funding. Whereas previous work assumed that admissions are governed by the...

The novel part of this paper is a model of the principle of proportionality, as the cornerstone of the doctrine of fundamental rights. German law, and with some modifications also the law of the European Community and the European Convention on Human Rights, do not categorically outlaw...

In this paper, we introduce two new learning models: impulse-matching learning and action-sampling learning. These two models together with the models of self-tuning EWA and reinforcement learning are applied to 12 different 2 x 2 games and their results are compared with the results from...

Bracketing is a mental procedure about how people deal with multiple tasks. If a decision maker handles all the tasks at the same time, it is called broad bracketing. If she handles the tasks separately, e.g., one or a few tasks each time, it is called narrow bracketing. This paper...

Evidence from an experiment investigating the "house money effect" in the context of a public goods game is reconsidered. Analysis is performed within the framework of the panel hurdle model, in which subjects are assumed to be one of two types: free-riders, and potential contributors. The...

In a full-information, zero transactions costs world, the degree of protection afforded to an entitlement does not affect the likelihood of efficient trade. In reality, imperfect information is often inevitable. Specifically, a party will usually have incomplete information about fairness norms...
