|October 2017||Are There Too Many Farms in the World? Labor-Market Transaction Costs, Machine Capacities and Optimal Farm Size|
with Mark R. Rosenzweig: w23909
This paper seeks to explain the U-shaped relationship between farm productivity and farm scale - the initial fall in productivity as farm size increases from its lowest levels and the continuous upward trajectory as scale increases after a threshold - observed across the world and in low-income countries. We show that the existence of labor-market transaction costs can explain why the smallest farms are most efficient, slightly larger farms least efficient and larger farms as efficient as the smallest farms. We show that to explain the rising upper tail of the U characteristic of high-income countries requires there be economies of scale in the ability of machines to accomplish tasks at lower costs at greater operational scales. Using data from the India ICRISAT VLS panel survey we find ev...
|August 2017||The Uptick in Income Segregation: Real Trend or Random Sampling Variance|
with John R. Logan, Jun Ke, Fan Li: w23656
Recent studies have reported a reversal of an earlier trend in income segregation in metropolitan regions, from a decline in the 1990s to an increase in the 2000-2010 decade. This finding reinforces concerns about the growing overall income inequality in the U.S. since the 1970s. We re-evaluate the trend. Because the effective sample for the ACS is much smaller than it was for Census 2000, to which it is being compared, there is a possibility that the apparent changes in disparities across census tracts result partly from a higher level of sampling variation and bias due to the smaller sample. This study uses 100% microdata from the 1940 census to simulate the effect of different sampling rates on the observed measure of inequality, drawing from a population at a single point in time s...
|May 2008||Institutions and Behavior: Experimental Evidence on the Effects of Democracy|
with Pedro Dal Bó, Louis Putterman: w13999
A novel experiment is used to show that the effect of a policy on the level of cooperation is greater when it is chosen democratically by the subjects than when it is exogenously imposed. In contrast to the previous literature, our experimental design allows us to control for selection effects (e.g. those who choose the policy may be affected differently by it). Our finding implies that democratic institutions may affect behavior directly in addition to having effects through the choice of policies. Our findings have implications for the generalizability of the results of randomized policy interventions.
