Washington's 'revolving door' - the movement from government service into the lobbying industry - is regarded as a major concern for policy-making. We study how ex-government staffers benefit from the personal connections acquired during their public service. Lobbyists with experience in the...

Tenured public officials such as judges are often thought to be indifferent to the concerns of the electorate and, as a result, potentially lacking in discipline but unlikely to pander to public opinion. We investigate this proposition empirically using data on promotion decisions taken by...

This paper presents a model of international portfolio choice based on the pattern of comparative advantage in goods trade. Countries have varying degrees of similarity in their factor endowment ratios, and are subject to aggregate productivity shocks. Risk averse consumers can insure against...

Although there is a large literature on the economic effects of minimum wages on labour market outcomes (especially employment), there is hardly any evidence on their impact on firm performance. This is surprising: minimum wages appear to have a significant impact on wages, but only a limited...

In this paper we study the causal impact of police on crime by looking at what happened to crime before and after the terror attacks that hit central London in July 2005. The attacks resulted in a large redeployment of police officers to central London boroughs as compared to outer London - in...

There is a growing body of research that measures employment effects of the minimum wage by using longitudinal data on individuals to compare job loss of workers affected by a minimum wage increase with those who are not directly affected. This sort of study requires good quality wage data in...

We survey the micro and macro literature on the impact of Information and Communication Technologies (ICTs) on productivity. The “Solow Paradox” of the absence of an impact of ICT on productivity no longer holds, if it ever did. Both growth accounting and econometric evidence suggest an...

This paper studies how investors react to public messages that may be optimistically biased. We first construct a communication game between an investor and a (possibly) biased securities analyst. We find an equilibrium characterised by the following properties: first, the investor reacts more...

We use a mechanism–design approach to study a team whose members choose a joint project and exert individual efforts to execute it. Members have private information about the qualities of alternative projects. Information sharing is obstructed by a trade–off between adaptation and...
