We analyze a dual currency search model in which agents are allowed to hold multiple units of both currencies. Hence, agents hold portfolios of currency. We study equilibria in which the two currencies are identical and equilibria in which the two currencies differ according to the magnitude of...

The paper explores the determinants of industry location across interwar Poland. After more than 120 years of political and economic separation, Poland was reunified at the end of 1918. In consequence, its industry faced massive structural changes: the removal of internal tariff barriers and...

We provide an analysis of the 2008-2009 trade collapse using microdata from a small open economy,Belgium. First, we find that changes in firm-country-product exports and imports occurred mostly atthe intensive margin: the number of firms, the average number of destination and origin markets...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

We investigate the dramatic 2008–2009 trade collapse using microdata from a small open economy, Belgium. Belgian trade essentially fell because of reduced quantities and unit prices, rather than fewer firms involved in international transactions, fewer trading partners per firm, or fewer...

This paper shows that in a non-representative agent model in which households face short selling constraints and labor income risk, in the form of both uninsurable shocks and a common aggregate component, small differences in the correlation between aggregate labor income shocks and domestic and...

This paper offers two main contributions. First, it shows how the Baxter and Jermann (1997) claim that, once we consider human capital risk, the international diversification puzzle is worse than we think, is based on an econometric misspecification rejected by the data. Second, it outlines how,...

With the Euro now a physical reality, Richard Layard argues that the economic case for Britain joining Euro-land is overwhelming.

In this article, we review the literature on the measurement of trade costs in international trade with a special emphasis on nontariff measures and in particular on standards and technical regulations. We distinguish ‘direct’ from ‘indirect’ approaches. The direct approach collects...
