We study the determinants of lifetime earnings (LE) inequality in the United States, for which differences in lifetime earnings growth are key. Using administrative data and focusing on the roles of job ladder dynamics and on-the-job learning, we document that 1) lower LE workers change jobs...

We ask which migration policy a developed country will choose when its objective is to attain the optimal skill composition of the country's workforce, and when the policy menu consists of an entry fee and a quota. We compare these two policies under the assumptions that individuals are...

The paper characterizes the optimal tax policy and the optimal quality of day care services in a OLG model with warm-glow altruism where parental choices over child care arrangements affect the probability that the child becomes a high-skilled adult in a type-speciffc way. With respect to...

Different types of labor and capital inputs have varying productive contributions that are dependent on plant characteristics. We estimate such contributions and their underlying determinants, recognizing the interactions among labor and capital components that reflect their substitutability or...

This paper constructs and estimates a structural dynamic model of occupational choice in which all occupations are characterized in a skill requirement space using data from the Dictionary of Occupational Titles and the NLSY79. This skill requirement space approach has its merit in computational...

This paper develops a model of optimal education choice of an agent who has an option to emigrate. Using a real options framework, we analyze the time evolution of human capital in the home country and investigate the role of migration opportunities in the accumulation of different types of...

While high fertility persists in the poorest countries and fertility declines with per capita income in developing countries, fertility and per capita income are now positively associated across most developed countries. This paper presents a model where a Ushaped relationship between overall...

There are at least three problems in the measurement of skill - aggregation, dynamism, and codification. Skill is an individual and collective capacity, expressed in performance and reflected in outcomes. Aggregate measures relying on proxies such as occupational entry qualifications may not...

We estimate month-of-birth effects on cognitive and noncognitive skills, as well as factors relevant to skill formation. Our estimates indicate that younger students in a given grade cohort have lower cognitive and noncognitive skills. To shed light on the underlying mechanisms, we also examine...
