In this paper we analyze how rati cation uncertainty impacts the optimal terms of international environmental agreements (IEAs). We relax the frequent assumption of countries as unitary actors by modeling the rati cation stage through uncertain preferences of a ratifying agent (e.g. the pivotal...

We allow a contest organizer to bias a contest in a discriminatory way; i.e., she can favor specific contestants by designing the contest rule in order to maximize total equilibrium effort (resp. revenue). The two predominant contest regimes are considered, all-pay auctions and lottery contests....

In using their citizen candidate framework, Besley and Coate (2001) fi nd that if citizen candidates with sufficiently extreme preferences are available, lobbying has no in fluence on equilibrium policy. I show that this result does not hold in a model with ideological parties instead of citizen...

This paper investigates the effects of different prize structures on the effort choices of participants in two-stage elimination contests. A format with a single prize is shown to maximize total effort over both stages, but induces low effort in stage 1 and high effort in stage 2. By contrast, a...

In this paper, citizens vote in order to influence the election outcome and in order to signal their unobserved characteristics to others. The model is one of rational voting and generates the following predictions: (i) The paradox of not voting does not arise, because the benefit of voting does...

We present an experiment in which extrinsic signals may generate sunspot equilibria. The game has a unique symmetric non-sunspot equilibrium, which is also risk dominant. Other equilibria can be ordered according to risk dominance. By comparing treatments with different information structure, we...

The strategy of adaptation to climate change has become a central topic within the UNFCCC negotiations in recent years. On the national level, adaptation plans are elaborated, and on the international level, the need for funding adaptation in developing countries is discussed. This tendency...

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

Dual-process theories view decisions as the result of the interaction of two qualitatively different types of processes, automatic/impulsive and controlled/deliberative. This paper considers a model of self-control where each decision can be taken by either an automatic process or a deliberative...

This paper analyzes a two-player all-pay auction with incomplete information. More precisely, one bidder is uncertain about the size of the initial advantage of his rival modeled as a head start in the auction. I derive the unique Bayesian Nash equilibrium outcome for a large class of cumulative...
