We study contestability in non-profit markets when non-commercial providers supply a homogeneous collective good through increasing-returns-to-scale technologies. Unlike in the case of for-profit competition, in the non-profit case the absence of price-based sales contracts means that fixed...

What are the dynamic consequences of comprehensive integration shocks? The answer to this question appears all but trivial. We set up a dynamic macroeconomic model of a small open economy where both capital and labor are mobile and there are increasing returns to scale at the aggregate level....

In this paper, we explore the role of trade in differentiated final goods as well offshoring of tasks for inequality both within and between countries. We emphasize the distinction between managerial and production labor. Production labor is assumed to be a variable input composed of tradable...

Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from...

This paper analyzes the link between the fact that fully endogenous growth models exhibit (or not) the non-desirable scale effects property and assumptions regarding the intensity of knowledge diffusion. In that respect, we extend a standard Schumpeterian growth model by introducing explicitly...

This paper reviews the economics approach to conflict and national borders. The paper (a) provides a summary of ideas and concepts from the economics literature on the size of nations; (b) illustrates them within a simple analytical framework where populations fight over borders and resources,...

Iceberg transport costs are one of the main ingredients of modern trade and economic geography models: transport costs are modelled by assuming that a fraction of the goods shipped “melts in transit”. In this paper, we investigate whether the iceberg assumption applies to the costs of...

Channel systems for conducting monetary policy are becoming increasingly popular. Despite its popularity, the consequences of implementing policy with a channel system are not well understood. The authors develop a general equilibrium framework of a channel system and study the optimal policy. A...

We study markets for perishable goods with search frictions. Sellers have a single unit of a good and post prices in every period. Buyers engage in costly search to observe prices and match values. In equilibrium trade starts endogenously and the volume of trade increases over time. Under mild...
