The recent literature on instrumental variables (IV) features models in which agents sort into treatment status on the basis of gains from treatment as well as on baseline-pretreatment levels. Components of the gains known to the agents and acted on by them may not be known by the observing...

This paper examines the correlated random coefficient model. It extends the analysis of Swamy (1971, 1974), who pioneered the uncorrelated random coefficient model in economics. We develop the properties of the correlated random coefficient model and derive a new representation of the variance...

This paper studies intergenerational mobility--the transmission of family influence. We develop and estimate measures of lifetime resources motivated by economic theory that account for differences in life-cycle trajectories, and uncertainty about future income. We identify the effects of...

This paper studies intergenerational mobility--the transmission of family influence. We develop and estimate measures of lifetime resources (income and wealth) motivated by economic theory that account for generational differences in life-cycle trajectories, uncertainty, and credit constraints....

This paper examines the economic foundations of three criteria used for evaluating the costs and benefits of social programs. Some criteria do not consider the scale of programs or address the costs associated with programs that expand or contract the total government budget. A recent addition...

We develop and estimate a life-cycle model in a rational addiction framework where youth choose to smoke, attend school, work part-time, and consume while facing borrowing constraints. The model features multiple channels for studying the reciprocal causal effects of addiction and education....

This paper considers the consequences of a two-sector vertically-integrated model of firms producing output using firm-specific capital with a second sector producing firm-specific capital by adapting raw capital purchased in the market. Analysts rarely observe each sector separately....

This paper summarizes empirical findings from a series of recent papers studying a replication of the Jamaica Reach Up and Learn home visiting program in China, China REACH. It collects more detailed information than is available on the original program. An analysis of it facilitates...
