"To assess the employment effects of labor costs, it is crucial to have reliable estimates of the labor cost elasticity of labor demand. Using a matched firm-worker data set, we estimate a long-run unconditional labor demand function, exploiting information on workers to correct for endogeneity...

Catalonia's economy is characterized by linguistic diversity and provides a unique opportunity to measure the incidence of language proficiency on over-education, particularly, whether individuals with deficient language skills tend to acquire more formal skills or, on the contrary, become...

This paper analyzes the problem of matching heterogeneous agents in a Bayesian learning model. One agent gives a noisy signal to another agent, who is responsible for learning. If production has a strong informational component, a phase of cross-matching occurs, so that agents of low knowledge...

This paper proposes a common and tractable framework for analyzing different definitions of fixed and random effects in a contant-slope variable-intercept model. It is shown that, regardless of whether effects (i) are treated as parameters or as an error term, (ii) are estimated in different...

I discuss the application of capture-recapture methods to estimating the total number of deaths in armed conflicts, and propose an alternative method based on a trivariate discrete choice model. Data come from the 'Truth and Reconciliation Commission' (TRC) of Peru, around 25000 deaths,...
