re individuals more likely to smoke when they are surrounded by smokers? In this paper, we examine the evidence for peer effects in smoking. We address the endogeneity of peers by looking at the impact of workplace smoking bans on spousal and peer group smoking. Using these bans as an...

Regulators must rely on science to understand problems and predict the consequences of regulatory actions, but science by itself cannot justify public policy decisions.

This paper considers policies of the industrialized countries, as they pertain to crises in emerging markets. These fall into three areas: (1) their own macroeconomic policies, which determine the global financial environment; (2) their role in responding to crises when they occur, particularly...
