In Fall 2014, Wellesley College began mandating pass/fail grading for courses taken by first-year, first-semester students, although instructors continued to record letter grades. We identify the causal effect of the policy on course choice and performance, using a...

We present new evidence on the influence of income inequality on generalized trust. Using individual panel data from Swedish counties together with an instrumental variable strategy we find that differences in disposable income, and especially differences among people in the bottom half of the...

We conduct an extensive robustness analysis of the relationship between trust and growth for a later time period (the 1990s) and with a bigger sample (63 countries) than previous studies. In addition to robustness tests that focus on model uncertainty, we use Least Trimmed Squares, a robust...

We present new evidence on how generalized trust is formed. Unlike previous studies, we look at the explanatory power of economic institutions, we use newer data, we incorporate more countries, and we use instrumental variables to handle the causality problem. A central result is that legal...

This paper explains people’s preferences for ethnic and racial diversity in higher education through a model based on self interest Although all citizens from the majority group value diversity and their own education in the same way their preferences for the level of diversity as well as the...

In this paper we evaluate the changes in the times-to-degree at the Finnish universities in the 1990s. In particular, we evaluate the effect of the 1992 student aid reform that was intended to shorten the duration of university studies. We find that the student aid reform had only a modest...

This paper focuses on the predictive validity of the upper secondary grade point average (GPA), when used as selection instrument to higher education. The purpose of the paper is to find out if the predictive strength of the GPA is affected by time, here measured as the time that has passed...

This paper estimates the effects on earnings of "gap years" between high school and university enrollment. The effect is estimated by means of standard earnings functions augmented to account for gap years and a rich set of control variables using administrative Swedish data. We find that...

We explore the evolution of the structure and performance of a social network in a population of individuals who search for local optima in diverse and dynamic task environments. Individuals choose whether to innovate or imitate and, in the latter case, from whom to learn. The probabilities of...
