This paper introduces a new theoretical framework of international unions qua coalitions of countries adopting a common policy and common supranational institutions. We introduce a general class of non-cooperative spatial bargaining games of coalition formation among three countries in order to...

We conducted a controlled field experiment on eBay and examined to what extent both social and competitive laboratory behavior is robust to institutionally complex real world markets with experienced traders, who selected themselves into these markets. EBay's natural trading system provides...

In this paper we investigate trade union formation. To this end we apply a model with two types of labour where the interests of both groups of labourers are represented by either a joint (industry) labour union or by two independent group-specific (professional) labour unions. We investigate...

This paper studies a decentralized, dynamic matching and bargaining market: buyers and sellers are matched into pairs. Traders exit the market at a constant rate, inducing search costs (frictions). All price offers are made by sellers. Despite the fact that sellers have all the bargaining power...

This article reports the results of a simple bargaining experiment on the ultimatum-revenge game. The game enables to differentiate between fairness that is stimulated by intentional based motives, distributional motives, and fairness considerations that mix both motives. The laboratory...

By settling and dropping out of the coalition, a plaintiff therefore creates a negative externality on the other...

Governments may draft contracts with market agents for allocating subsidies and pursuing specific policy goals. Contract enforcement via binding commitments is difficult, however, when exogenous (environmental) and endogenous (behavioural) risks interact. Analyzing the old debt compromise in...

Consider a decentralized, dynamic market with an infinite horizon in which both buyers and sellers have private information concerning their values for the indivisible traded good. Time is discrete, each period has length ä, and each unit of time a large number of new buyers and sellers enter...
