[ES] Este trabajo evalúa la política tributaria vigente en Chile desde la perspectiva del criterio de Igualdad de Oportunidades. Bajo este criterio es deseable actuar para compensar a las personas por las circunstancias en las que nacen, pero es necesario permitir las diferencias originadas...

We study the supercore of a system derived from a normal form game. For the case of a finite game with pure strategies, we define a sequence of games and show that the supercore of that system coincides with the set of Nash equilibrium strategy profiles of the last game in the sequence. This...

This paper analyzes the consequences of the interaction between two different levels of government (regulators) in the development of housing policy when their decisions determine the level of competition in the housing market. The analysis discusses the implications derived from a lack of...

We analyze the von Neumann and Morgenstern stable sets for the mixed extension of 2 2 games when only single profitable deviations are allowed. We show that the games without a strict Nash equilibrium have a unique vN&M stable set and otherwise they have infinite sets.

Breast cancer and cervical cancer are the most common female cancers in Spain and in many developed countries. The main goal of this paper is to identify the determinants of individual decisions on breast screening and smear testing, that is to say, the decision to take a test for the first time...

Most of the patent licensing agreements that are observed include royalties, in particular per-unit or ad valorem royalties. This paper shows that in a differ entiated duopoly that competes á la Cournot the optimal contract for an internal patentee always includes a positive royalty. Moreover,...

This paper analyzes the strategic choice of variety by a monopolist seller of a durable good as a means to mitigate his commitment problem. The monopolist chooses his product variety with a goal of ensuring that a strong reduction in future prices will not be profitable because it allows the...

The problem of specification errors in sample selection models has received considerable attention both theoretically and empirically. However, very few is known about the finite sample behavior of two step estimators. In this paper we investigate by simulations both bias and finite sample...
