Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just part of a long run interaction. Unfortunately, it is not easy to reach those conditions and ...

Building on Item Response Theory we introduce students’ optimal behavior in multiple-choice tests. Our simulations indicate that the optimal penalty is relatively high, because although correction for guessing discriminates ...

In a context where demand for the services of a durable good changes over time, and this change may be uncertain, the paper shows that social welfare may be higher when the monopolist seller can commit to any future price ...

In this paper we study the evolution of income inequality for employees and self-employed workers. We highlight the importance of separately analyze these different sources of income to gain a broader understanding of ...

Using the ECHP, we explored the determinants of having the first child in Spain. Our main goal was to study the relation between female wages and the decision to enter motherhood. Since the offered wage of non-working women ...

We examine competition in Mobile Internet services, when operators bargain over the coverage sharing and their reciprocal roaming charge. Results show that in equilibrium operators cover the overall territory entirely and ...

A disadvantage of multiple-choice tests is that students have incentives to guess. To discourage guessing, it is common to use scoring rules that either penalize wrong answers or reward omissions. These scoring rules are ...

Potential efficiency gains due to a merger can be used by competition authorities to judge upon proposed mergers. In a world where agents’ efforts, observable or unobservable, affect the success of a production cost reducing ...

In this work we emphasize why market coverage should be considered endogenous for a correct analysis of entry deterrence in vertical differentiation models and discuss the implications of this endogeneity for that analysis. ...

This paper is concerned with the study of durability as an aspect of competition and market structure that contributes to determining the incentives for mergers. We find that relative to the incentives in industries that ...
