Structural Change in Labor Supply and Cross-Country Differences in Hours Worked
This paper studies how structural change in labor supply along the development spectrum shapes cross-country differences in hours worked. We emphasize two main forces: sectoralreallocation from self-employment to wage work, and declining fixed costs of wage work. We show that these forces are crucial for understanding how the extensive margin (the employment rate) and intensive margin (hours per worker) of aggregate hours worked vary with income per capita. To do so we build and estimate a quantitative model of labor supply featuring a traditional self-employment sector and a modern ...

Social security and the consumer price index for the elderly
Some argue that social security benefits should be adjusted using a price index that reflects the spending habits of the elderly rather than those of workers. This study suggests that if such an index were adopted today, over the next forty years benefit levels would increase and the social security trust fund could become insolvent up to five years sooner than projected.

The Welfare Effects of Encouraging Rural-Urban Migration
This paper studies the welfare effects of encouraging rural-urban migration in the developing world. To do so, we build and analyze a dynamic general-equilibrium model of migration that features a rich set of migration motives. We estimate the model to replicate the results of a field experiment that subsidized seasonal migration in rural Bangladesh, leading to significant increases in migration and consumption. We show that the welfare gains from migration subsidies come from providing better insurance for vulnerable rural households rather than correcting spatial misallocation by relaxing ...

Inflation inequality in the United States
Inflation is often assumed to affect all people in the same way. In practice, differences in spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation for different households. In this paper, we measure the degree of inequality in inflation across U.S. households for the period 1987-2001. ; Our results suggest that the inflation experiences of U.S. households vary significantly. Most of the differences can be traced to changes in the relative prices of education, health care, and gasoline. We find that cost of living ...

Superstores or mom and pops? Technolgy adoption and productivity differences in retail trade
I document that cross-country productivity differences in retail trade, which employs around 20% of workers, are accounted for in large part by compositional differences. In richer countries, most retailing is done in modern stores, with high measured output per worker, whereas in developing countries, retail trade is dominated by less-productive traditional stores. I hypothesize that developing countries rationally adopt few modern stores since car ownership rates are low. A simple quantitative model of home production supports the role of cars in determining the composition of retail ...
