A seller dynamically sells a divisible good to a buyer. It is common knowledge that there are gains from trade and that the gains per unit are decreasing. Payoffs are interdependent as in Akerlof's market for lemons. The seller is informed about the good's quality. The buyer makes an offer in...

This paper investigates the effect of potential competition on takeovers which we model as a bargaining game with alternating offers where calling an auction represents an outside option for each bidder at each stage of the game. The model aims to answer three main questions: who wins the...

We model a situation in which two countries are involved in a dispute. The dispute can end in a peaceful settlement, or it can escalate to war. If it is common knowledge that the countries are strategically rational, then the only equilibrium outcome of the model is peace. If, on the other hand,...

We examine the buyer-seller problem under different levels of commitment. The seller is informed of the quality of the good, which affects both his cost and the buyer's valuation, but the buyer is not. We characterize the allocations that can be achieved through mechanisms in which, unlike with...

We define and investigate a new class of measure-valued Markov chains by resorting to ideas formulated in Bayesian nonparametrics related to the Dirichlet process and the Gibbs sampler. Dependent random probability measures in this class are shown to be stationary and ergodic with respect to the...

The paper proposes a new nonparametric prior for two-dimensional vectors of survival functions (S1,S2). The definition we introduce is based on the notion of Lévy copula and it will be used to model, in a nonparametric Bayesian framework, two-sample survival data. Such an application will yield...

A Bayesian nonparametric methodology has been recently proposed in order to deal with the issue of prediction within species sampling problems. Such problems concern the evaluation, conditional on a sample of size n, of the species variety featured by an additional sample of size m. Genomic...

A random distribution function on the positive real line which belongs to the class of neutral to the right priors is defined. It corresponds to the superposition of independent beta processes at the cumulative hazard level. The definition is constructive and starts with a discrete time process...

We present a theoretical model of the provision of a durable public good over an infinite horizon. In each period, there is a societal endowment of which each of n districts owns a share. This endowment can either be invested in the public good or consumed. We characterize the planner's optimal...
