Effects of Legal Status on Immigrants Working in Agriculture
We show that legal status (citizen, green card, Amnesty, undocumented worker) affects earnings, retention and turnover rates, migration patterns, use of public welfare and private aid programs, and working conditions of agricultural workers. We also examined the effects of efficiency (unusually high) wages and deferred payments as incentives to agricultural workers.
Forecasting Unemployment Rates
We developed new statistical methods to more accurately predict unemployment rates using only information about past rates.
We developed new statistical methods to estimate the entire Chinese rural and urban income distributions when the government provides only a few summary statistics. We find that these distributions have become more unequal over time and that urban incomes have risen more rapidly than rural ones and provide explanations for these changes (see figures). China and the United States have virtually identical Gini coefficients (a common measure of income inequality) and very similar overall income distributions (see the figure).
Government Policies and Income Distribution
We estimated the effects of all major national and state policies (minimum wages, taxes, welfare, social insurance) on income distributions. We find that taxes have by far the strongest effects and that policies such as taxes and minimum wages laws have different effects in rural and urban areas.
