We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price (LOOP). For identical products, we find typical deviations of twenty to fifty percent, though there is muted evidence for convergence over time. Such...

In what sense are institutions a deep determinant of growth? In this paper, we address this question by examining the relationship between city growth and institutional reform in 19th century Germany, when some cities experienced deep institutional reform as a result of French rule. Employing an...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

In many OECD countries, e.g. in Germany, France, or the UK, unemploy-ment compensation consists of unemployment insurance and unemployment assistance. Unemployment assistance is provided subsequent to the expiration of entitlement to unemployment insurance and is lower. The effects of this...

This paper examines the welfare implications of preferential trade agreements (PTAs) from the perspective of small countries in the context of a multi-country, general equilibrium model. We calibrate our model to represent one relatively small country and two symmetric big countries. We consider...

This short paper reconsiders the popular result that the lower the probability of getting reelected, the stronger the incumbent politicians' incentive to follow short-sighted, inefficient policies. The set-up is a general equilibrium model of endogenous growth and optimal fiscal policy, in which...

We consider a general equilibrium model where groups operating in a competitive market environment can have several members and make efficient collective consumption decisions. Individuals have the option to leave the group and make it on their own or join another group. We study the effect of...
