We analyze data on NYPD's "stop and frisk program" in an effort to identify racial bias on the part of the police officers making the stops. We find that the officers are not biased against African Americans relative to whites, because the latter are being stopped despite being a "less...

A single worker allocates her time among different projects which are progressively assigned. When the worker works on too many projects at the same time, the output rate decreases and completion time increases according to a law which we derive. We call this phenomenon "task juggling" and argue...

We show that task juggling, i.e., the spreading of effort across too many active projects, decreases the performance of workers, raising the chances of low throughput, long duration of projects and exploding backlogs. Individual speed of job completion cannot be explained only in terms of...

(Documento disponible en inglés) ¿Existe una relación entre educación y democracia? Una vez que se introduce una corrección de la debilidad de instrumentos y se describe a la educación como `débilmente exógena`, se hallan nuevos elementos de juicio de que la educación predice la...

Is there any relation between education and democracy? Once we correct for weak instruments and identify education as `weakly exogenous` we find new evidence that education systematically predicts democracy. Our results are robust across model specification, instrumentation strategies, and samples.

Disputes on the penalties enforceable for breach of contract are often solved in court. Using a large dataset on Italian public procurement contracts, we study the effects of the inefficiency of the local law courts on the delay with which contractors deliver public works. First we sketch a...

We document whether and how publicizing a public procurement auction causally affects entry and the costs of procurement. We run a regression discontinuity design analysis on a large database of Italian procurement auctions. Auctions with a value above the threshold must be publicized in the...
