An estimated 20 million children born each year are at risk of brain damage from in utero iodine deficiency, the only micronutrient deficiency known to have significant, non-reversible effects on cognitive development. Cognitive damage from iodine deficiency disorders (IDD) has potentially...

Commitment devices offer an opportunity to restrict future choices. However, if severe restrictions deter participation, weaker restrictions may be a more effective means of changing behavior. We test this using a school-based commitment savings device for educational expenses in Uganda. We...

We introduce the concept of financial competence, a measure of the extent to which individuals' financial choices align with those they would make if they properly understood their opportunity sets. Unlike existing measures of the quality of financial decision making, the concept is firmly...

In the early 2000s, a highly selective university introduced a "no-loans" policy under which the loan component of financial aid awards was replaced with grants. We use this natural experiment to identify the causal effect of student debt on employment outcomes. In the standard life-cycle model,...

This paper posits a notion of the value of an individual's human capital and the associated return on human capital.

This paper reviews the recent literature on the production of skills of young persons. The literature features the multiplicity of skills that explain success in a variety of life outcomes. Noncognitive skills play a fundamental role in successful lives. The dynamics of skill formation reveal...

We use heterogeneity in the timing of television's introduction to different local markets to identify the effect of preschool television exposure on standardized test scores later in life. Our preferred point estimate indicates that an additional year of preschool television exposure raises...

Low-achieving students in many school districts are retained in a grade in order to allow them to gain the academic or social skills that teachers believe are necessary to succeed academically. This practice is highly controversial, with many researchers claiming that it leads to higher dropout...

We estimate the impact of compulsory schooling on earnings using the changes in compulsory schooling laws for secondary schools in West German states during the period from 1948 to 1970. While our research design is very similar to studies for various other countries, we find very different...

We use the unique experiences of Canadian World War II veterans to identify the effects of a large scale college subsidy program on educational attainment and earnings. Like the United States, Canada set up an extensive veteran's assistance program that provided financial aid and institutional...
