We show how standard consumer and producer theory can be used to estimate welfare in insurance markets with selection. The key observation is that the same price variation needed to identify the demand curve also identifies how costs vary as market participants endogenously respond to price....

We use book translations as a new measure of international idea flows and study the effects of Communism’s collapse in Eastern Europe on these flows. Using novel data on 800,000 translations, we show that while translations between Communist languages decreased by two thirds with the collapse,...

A new generation of information and communication infrastructures, including advanced Internet computing and Grid technologies, promises more direct and shared access to more widely distributed computing resources than was previously possible. Scientific and technological collaboration,...
