We propose a method of estimating the Pareto tail thickness parameter of the unconditional distribution of a financial time series by exploiting the implications of a GJR-GARCH volatility model. The method is based on some recent work on the extremes of GARCH-type processes and extends the...

This paper develops methodology for nonparametric estimation of a polarization measure due to Anderson (2004) and Anderson, Ge, and Leo (2006) based on kernel estimation techniques. We give the asymptotic distribution theory of our estimator, which in some cases is nonstandard due to a boundary...

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that the variables are allowed to be residuals from...

En el presente trabajo se estiman los costes indirectos (pérdidas de productividad laboral) ocasionados en España por los tumores, y en particular por cuatro tipos concretos: mama, cérvix, próstata y colon. Además de los costes que originan su tratamiento y prevención, las enfermedades...

En este trabajo se analiza la producción científica los investigadores españoles, o que trabajan en instituciones españolas, en el área de Economía durante la década de los noventa. Se utilizan varios índices bibliométricos para elaborar rankings por instituciones e investigadores que...

We test the strategic motive to sell forward in experimental Cournot duopoly and quadropoly environments with either a finite (exogenous close) or an infinite (endogenous close) number of forward markets. In the exogenous close case experienced subjects do not avail themselves of the forward...

In this paper, we address the issue of how the possibility for areements among network operators about building joint facilities affects their networks qualities, their profits and social welfare. We show that allowing the network operators to build joint facilities can make the network...

This paper presents new evidence from Spain that challenges the usual objections to the possibility of applying the rental equivalent approach to determine the weight that non-rental housing services should have in the CPI. Data from the EPFs (Encuestas de Presupuestos Familiares) for 1980-81...

We provide an example of an outcome game form with two players for which there is in an open set of utilities for both players such that, in each of the associated games, the set of Nash equilibria induce a continuum of outcome distributions. The case for three or more players has been settled...

This paper reviews the properties suggested in the methodological literature on the measurement of gender segregation by occupation. It is found that an index of segregation based on the entropy concept satisfies twelve basic axioms previously proposed in the single-dimensional case. This index...
