We consider a dynamic economy in which agents are repeatedly matched and decide whether or not to form profitable partnerships. Each agent has a physical color and a social color. An agent's social color acts as a signal, conveying information about the physical color of agents in his...

In Mexico, as in most Latin American countries with indigenous populations, it is commonly believed that European phenotypes are preferred to mestizo or indigenous phenotypes. However, it is hard to test for such racial biases in the labor market using official statistics since race can only be...

The stigma associated with long-term unemployment spells could create large inefficiencies in labor markets. While the existing literature points toward large stigma effects, it has proven difficult to estimate causal relationships. Using data from a field experiment, we find that long-term...

We study minority representation in the workplace when employers engage in optimal sequential search and minorities convey noisier signals of ability than mainstream job candidates. The greater signal noise makes it harder for minorities to change employers' prior beliefs. When employers are...

We consider a market with "red" and "green" workers, where labels are payoff irrelevant. Workers may acquire skills. Skilled workers search for vacancies, while firms search for workers. A unique symmetric equilibrium exists in which color is irrelevant. There are also asymmetric equilibria in...

We study how diversity evolves at a firm with entry-level and upper-level employees who vary in ability and "type" (gender or ethnicity). The ability of entry-level employees is increased by mentoring. An employ receives more mentoring when more upper-level employees have the same type. Optimal...

A change in the audition procedures of symphony orchestras--adoption of "blind" auditions with a "screen" to conceal the candidate's identity from the jury--provides a test for sex-biased hiring. Using data from actual auditions, in an individual fixed-effects framework, we find that the screen...

Until the middle of the 1970s, regulations constrained banks' ability to enter new markets. Over the subsequent 25 years, states gradually lifted these restrictions. This paper tests whether rents fostered by regulation were shared with labor, and whether firms were discriminating by sharing...
