In speedboat racing in Japan, women racers participate and compete in races under the same conditions as men, and all individuals are randomly assigned to mixed-gender or single-gender groups for each race. In this paper we use a sample of over 140,000 observations of individual-level racing...

Agency theory suggests the use relative performance evaluation (RPE) to filter out systematic risks from a noisy performance measure. The presence of exposure risk, i.e. if the exposure to the systematic risks moves over time, however precludes complete filtering. In the present study I first...

We assess the magnitude and mechanisms of workers' productivity spillovers by estimating the peer effects among those working in the same occupation across firms using the setting of security analysts. The empirical design exploits one feature of social networks: the existence of partially...

We study the implementation of Bolsa Familia, a program that conditions cash transfers to poor families on children's school attendance. Using unique administrative data, we analyze how beneficiaries respond to the enforcement of conditionality. Making use of random variation in the day on which...

This article examines role of peer effects in determining corporate board structures. We use differences in new guidelines by NYSE and NASDAQ post Sarbanes-Oxley to construct a novel instrument to estimate our peer effects model. We find a strong presence of peer effects in determining board...

We present a conceptual framework linking cultural heterogeneity to inter-group conflict. When conflict is about control of public goods, more heterogeneous groups are expected to fight more with each other. In contrast, when conflict is about rival goods, more similar groups are more likely to...

It is notoriously difficult to identify peer effects within the family, because of the common shocks and reflection problems. We make use of a novel identification strategy and unique data in order to gain some purchase on this problem. We employ data from the universe of children born in...

We investigate whether peer effects at work differ by gender and whether the gender difference in peer effects – if any – depends on work organization, precisely the structure of social networks. We develop a social network model with gender heterogeneity that we test by means of a...

We investigate whether peer effects at work differ by gender and whether gender differences in peer effects - if any - depend on work organization. We develop a social network model with gender heterogeneity that we test in a real-effort laboratory experiment. We compare sequential networks in...

Using a theoretical model where students care about achievement rank, I study effort choices in the classroom and show that rank concerns generate peer effects. The model's key empirical prediction is that the effect on own achievement of increasing the dispersion in peer cost of effort is...
