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 documents a set of stylized facts about recent trends in cross-border M&A (CBMA) activity around the world. 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...

In the last two decades the European financial markets have become more market oriented. We analyze the economic and political forces that have triggered these changes as well as their likely welfare implications. We also try to assess whether this trend will continue. Based on our analysis, we...

The internal market in Europe will greatly increase the international mobility of resources. How will this affect fiscal policy in different countries? The first part of the paper considers taxation of capital in a two country model, where a democratically chosen government in each country...

Can patent protection and product market competition complement each other in enhancing incentives to innovate? In this paper, we address this question by investigating how innovation responses to a substantial policy initiative increasing product market competition interact with the strength of...

Patterns of political unification and fragmentation have crucial implications for comparative economic development. Diamond (1997) famously argued that "fractured land" was responsible for China's tendency toward political unification and Europe's protracted political fragmentation. We build a...

We analyze the conduct of fiscal policy in a financially integrated union in the presence of financial frictions. Frictions create a wedge between the return to investment and the union interest rate. This leads to an over-spending externality. While the social cost of spending is the return to...
