We study time-consistent bank resolution mechanisms. When interventions are ex post efficient, a government cannot commit not to inject capital into the banking system. Contrary to common wisdom, we show that the government may still avoid moral hazard and implement the first best allocation by...

We compare risk sharing in response to demand and supply shocks in four types of currency unions: segmented markets; a banking union; a capital market union; and complete financial markets. We show that a banking union is efficient at sharing all domestic demand shocks (deleveraging, fiscal...

This paper assesses the potential impact of FinTech on the finance industry, focusing on financial stability and access to services. I document first that financial services remain surprisingly expensive, which explains the emergence of new entrants. I then argue that the current regulatory...

We study the optimal use of disclosure and fiscal backstops during financial crises. Providing information can reduce adverse selection in credit markets, but negative disclosures can also trigger inefficient bank runs. In our model governments are thus forced to choose between runs and lemons....

We examine the relationship between immigration and attitudes toward redistribution using a newly assembled data set of immigrant stocks for 140 regions of 16 Western European countries. Exploiting within-country variations in the share of immigrants at the regional level, we find that native...

This paper investigates whether or not the adoption of the Euro has facilitated the introduction of structural reforms, defined as deregulation in the product markets and liberalization and deregulation in the labor markets.

In this paper, we present our view of the recent evolution of European integration. We first briefly describe the main features of the institution and decision making process in the European Union, with particular attention to the debate between federalists and super nationalists. We then...

We construct a set of indicators to measure the policy-making role of the European Union (European Council, Parliament, Commission, Court of Justice, etc.), in a selected number of policy domains. Our goal is to examine the division of prerogatives between European institutions and national...

What is the optimal number of currencies in the world? Common currencies affect trading costs and, thereby, the amounts of trade, output, and consumption. From the perspective of monetary policy, the adoption of another country's currency trades off the benefits of commitment to price stability...
