Using a newly assembled data set on procedures filed in Mexican labor tribunals, we study the determinants of final awards to workers. On average, workers recover less than 30% of their claim. Our strongest result is that workers receive higher percentages of their claims in settlements than in...

The access pricing problem emerges when a vertically integrated firm (the incumbent) provides an essential service in the upstream market, to an entrant. Both firms produce a final service and compete in the downstream market. The standard treatment of this problem has been to add the access...

We analyze the outcomes of 332 cases from a labor court in Mexico in which a judge awarded money to a plaintiff who claimed to have been fired by a firm without cause. The judgments were enforced in only 40% of the cases. A plaintiff may try to enforce a judgment by petitioning the court to...

The authors analyze lawsuits involving publicly-appointed lawyers in a labor court in Mexico to study how a rigid law is enforced. They show that, even after a judge has awarded something to a worker alleging unjust dismissal, the award goes uncollected 56 percent of the time. Workers who are...

We test for the presence of long memory in daily stock returns and their squares using a robust semiparametric procedure. Spurious results can be produced by nonstationarity and aggregation.

Most hypotheses in binary response models are composite. The null hypothesis is usually that one or more slope coefficients are zero. Typically, the sequence of alternatives of interest is one in which the slope coefficients are increasing in absolute value. In this papar, we prove that the...

Modern econometrics requires implementation of highly specialized software. In contrast to mathematical arguments used in implementing new econometric techniques the corresponding software algorithms require specific platforms. The specialization of hardware and software, in fact, seriously...
