We investigate whether TV watching at ages 6-7 and 8-9 affects cognitive development measured by math and reading scores at ages 8-9 using a rich childhood longitudinal sample from NLSY79. Dynamic panel data models are estimated to handle the unobserved child-specific factor, endogeneity of TV...

Arguably the fundamental problem faced by employers is how to elicit effort from employees. Most models suggest that employers meet this challenge by monitoring employees carefully to prevent shirking. But there is another option that relies on heterogeneity across employees, and that is to...

This paper estimates production functions of child cognitive and social development using a panel data of nine-year old children each with over two hundred home and school inputs as well as family background variables. A tree regression method is used to conduct estimation under various...

This paper establishes a simple model of long run economic and political development, which is driven by the inherent technical features of dierent production factors and the political con.icts among factor owners on how to divide the outputs. The main production factor in economy evolves from...

This paper studies the transition of contract enforcement institutions. The prevalence of relational contracts, low legal quality, strong cultural preference for personalistic relationships, low social mobility, and highly unequal endowment form a cluster of mutually reinforcing institutions...

There has been much recent interest in the effects of pre and non-market skills on future labor market outcomes. This paper examines one such effect : the effect on future wages of military leadership experience among "Vietnam generation" American men. We study rank, not just veteran status. We...
