We test the effectiveness of self-help peer groups as a commitment device for precautionary savings, through two randomized field experiments among 2,687 microentrepreneurs in Chile. The first experiment finds that self-help peer groups are a powerful tool to increase savings (the number of...

For three years after the typical emerging economy opens its stock market to inflows of foreign capital, the average annual growth rate of the real wage in the manufacturing sector increases by a factor of three. No such increase occurs in a control group of countries. The temporary increase in...

This paper examines the effect of exogenous shocks to savings on world capital markets. Using the exogenous shocks to US tax policy identified by Romer & Romer, we trace the impact of an exogenous shock to savings through the income accounting identities of the US and the rest of the world. We...

International risk-sharing has far-reaching implications both for economic policy and for basic research in economics. When countries do not share risk, individuals in those countries experience fluctuations in their consumption levels that are undesirable and possibly unnecessary. This paper...

Using a variance decomposition of shocks to GDP, we quantify the role of international factor income, international transfers, and saving in achieving risk sharing during the recent European crisis. We focus on the sub-periods 1990-2007, 2008-2009, and 2010 and consider separately the European...

Reforms of indirect taxes, such as the recent changes in rates of value added tax (VAT) in the Czech Republic, change prices of products and services to which households can respond by adjusting their expenditures. I estimate the behavioural response of consumers to price changes in the Czech...

Models of consumer behavior play a key role in modern empirical industrial organization. In this review, I survey some of the models used in this literature. In particular, I discuss two commonly used demand systems: multistage budgeting approaches and discrete choice models. I motivate their...
