The dramatic implosion and regionalization of international trade during the 1930s has often been blamed on the trade and foreign exchange policies that emerged in the interwar period. We provide new evidence on the impact of trade and currency blocs on trade flows from 1928 1938 that suggests a...

Recent proposals for enlarging the European Community to include the EFTA countries raise the question of whether the new members should participate in a European Monetary Union. In part, the issue hinges on the incidence of aggregate supply and demand disturbances. We use data on prices and...

Employing a wide range of individual-level surveys, we study the extent of cultural and institutional heterogeneity within the EU and how this changed between 1980 and 2008. We present several novel empirical regularities that paint a complex picture. While Europe has experienced both systematic...

Entering a currency union without any political union European countries have taken a gamble: will the needs of the currency union force a political integration (as anticipated by Monnet) or will the tensions create a backlash, as suggested by Kaldor, Friedman and many others? We try to answer...

This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. We present a model providing a theoretical foundation to estimate empirically the effects of political borders on growth. In our model, political...

We model an international union as a group of countries deciding together the provision of certain public goods and policies because of spillovers. The countries are heterogeneous either in preferences and/or in economic fundamentals. The trade off between the benefits of coordination and the...

The facts focus on key features of CBMA such as (i) the magnitude; (ii) how it varies across industries and locations; (iii) how it compares to levels of greenfield FDI over time;...

Are country borders still an impediment to trade flows within Europe? Using a rich microlevel survey with 3 million annual shipments of goods by road across 269 European regions, we construct a matrix of bilateral trade flows for 12 industries from 2011 to 2017. We then use the causal inference...

Most observers have concluded that while money markets and government bond markets are rapidly integrating following the introduction of the common currency in the euro area, there is little evidence that a similar integration process is taking place for retail banking. Data on cross-border...
