Over the past decade there has been a decline in the fraction of papers in top economics journals written by economists from the highest-ranked economics departments. This paper documents this fact and uses additional data on publications and citations to assess various potential explanations....

A large literature following Hirsch (2005) has proposed citation-based indexes that could be used to rank academics. This paper examines how well several such indexes match labor market outcomes using data on the citation records of young tenured economists at 25 U.S. departments. Variants of...

Presenting data on all full-length articles published in the three top general economics journals for one year in each of the 1960s through 2010s, I analyze how patterns of co-authorship, age structure and methodology have changed, and what the possible causes of these changes may have been. The...

We estimate a dynamic learning model of the college dropout decision, taking advantage of unique expectations data to greatly reduce our reliance on assumptions that would otherwise be necessary for identification. We find that forty-five percent of the dropout that occurs in the first two...

The rising importance of Information Technology (IT) occupations in the U.S. economy has been accompanied by an expansion in the representation of high-skill foreign-born IT workers. To illustrate, the share of foreign born in IT occupations increased from about 15.5% to about 31.5% between 1993...

Understanding how returns to higher education vary across degree programs is critical for effective higher education policy. Yet there is little evidence as to whether all degrees improve labor market outcomes, and whether they do so for students from different types of backgrounds. We combine...

At an annual cost of roughly $7 billion nationally, remedial coursework is one of the single largest interventions intended to improve outcomes for underprepared college students. But like a costly medical treatment with non-trivial side effects, the value of remediation overall depends upon...

We show that data on subjective expectations, especially on outcomes from counterfactual choices and choice probabilities, are a powerful tool in recovering ex ante treatment effects as well as preferences for different treatments. In this paper we focus on the choice of occupation, and use...

One of the continuing areas of controversy surrounding higher education is affirmative action. The Supreme Court has agreed to hear Fisher v. Texas, and their ruling may well influence universities' diversity initiatives, especially if they overturn Grutter v. Bollinger and rule that diversity...

We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted...
