We develop a signalling-game theoretical model to study a policy that publicly reports hospital waiting times. We characterize two effects of such a policy: the "competition effect" that drives hospitals to compete for patients by increasing service rates and reducing waiting times, and the...

This paper proposes a possible explanation for uniform pricing in the recorded music industry, based on a pooling equilibrium across different quality types. We show that an ex ante ability to invest in the probability of success - which we identify with record companies' A&R expenditures -...

This paper defines simple procedures to construct ambiguous perturbations of belief structures associated to standard type spaces with precise beliefs, based on ambiguous type spaces whose induced belief hierarchies approximate the belief hierarchies corresponding to the initial type space. Two...

Macroeconomists working with multivariate models typically face uncertainty over which (if any) of their variables have long run steady states which are subject to breaks. Furthermore, the nature of the break process is often unknown. In this paper, we draw on methods from the Bayesian...

This paper constructs a model of the provision of commercial music in which some consumers (enthusiasts) enjoy diversity and others (faddists) prefer to follow what is popular. Record companies sign up bands, only some of whom will 'succeed' - a process modelled in a number of alternate ways -...

In this paper we study the endogenous choice to accept fiat objects as media of exchange, the fundamentals that drive their acceptance, and their implications for their bilateral nominal exchange rate. To this end, we consider a small open economy where agents have no restrictions on what...

Empirical work in macroeconometrics has mostly restricted to using VARs, even though there are strong theoretical reasons to consider general VARMAs. This is perhaps because estimation of VARMAs is perceived to be challenging. In this article, we develop a Gibbs sampler for the basic VARMA, and...

A signicant number of individuals are unwilling to deposit their savings into the banking sector since it does not operate according to their religious beliefs. In this paper we provide a model that aims to answer the following questions: First, under what conditions an alternative banking...
