We analyze the regulation of a single health care provider (e.g. a hospital). According to several payment rules used in different countries, we consider a mixed linear payment in which the hospital is paid a fixed price per DRG (diagnosis related group) for most patients (inlier patients) and...

Using entropy indices and associated bootstrap tests, we describe the distribution of economic sectors across Western European regions over the 1975-2000 period. We decompose geographic concentration into its within-country and between-country components. In addition, we estimate centre...

This is a survey of the literature on liquidity provision through banks. I first formulate the basic model underlying the modern literature on liquidity provision for households and then introduce the more recent literature on liquidity provision through banks and markets. Then I turn to...

This paper is about freedom of choice and rigidity of choice rules as incentive devices. We study the optimal design of an agent's freedom of choice when his information is endogenous and costly to acquire.

This paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities. The possibility of multiple equilibria, including a 'currency crisis' equilibrium with low output and a...
