We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioural rules of thumb...

This paper analyses a situation where market designers create new trading platforms and traders learn to select among them. We ask whether 'Walrasian' platforms, leading to market-clearing trading outcomes, will dominate the market in the long run. If several market designers are competing, we...

In this paper we examine the main challenges in promoting an effective market economy. While the paper ranges widely across the spectrum of economic institutions and policies, the central theme is the importance of macroeconomic stability for economic growth in the medium and long run....

We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two-city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when...

Trade in business services has been attracting attention from academic researchers, policy makers, and business journalists. While there are many anecdotes, there has been little in the way of formal theory applied to this issue. In this paper, we adapt a general model of fragmentation of...

This paper examines the impact of policy-makers' horizons on the sustainability of international cooperation. We describe a prisoners' dilemma game between two infinitely-lived organizations (countries) run by agents (policy-makers) with a shorter tenure. The agents' mandates are finite but...

Economic integration, from the European Payments Union and the European Coal and Steel Community to the Common Market, the European Monetary System, the Single Market, and the euro, is one of the most visible, controversial and commented-upon aspects of Europe’s development since the end of...

Bilateral, product-level data exhibit a number of strong patterns that can be used to evaluate international trade theories, notably the spatial incidence of "export zeros" (correlated with distance and importer size), and of export unit values (positively related to distance). We show that...

The paper uses long-run GDP data for developed countries drawn from Maddison (2003) to generate deviation cycles for the period from 1870 to 2001. The cyclical deviates are examined for their bilateral cross-correlation values in three separate periods, those of the first globalization wave...

This paper reviews the problems that must be resolved at the Intergovernmental Conference in 1996 to clear the way for European Monetary Union: locking in Germany's commitment to the project, and reconciling EMU with variable geometry. It reviews what we know about the costs and benefits of EMU...
