En el presente documento se analizan algunas variables de la configuración estructural de la empresa gallega y su relación con la dimensión (medido por el número de empleados), el sector de actividad y el grado de satisfacción con los resultados. Para ello construimos una tipología de las...

En este trabajo se pretende realizar una aproximación a la determinación de curvas de Engel y elasticidades en el campo del Análisis de Presupuestos Familiares. Se revisan los modelos parámetricos más usuales en este campo y se analizan sus resultados comparándolos con una estimación de...

We present a new method for constructing exact distribution-free tests (and confidence intervals) for variables that can generate more than two possible outcomes. This method separates the search for an exact test from the goal to create a non- randomized test. Randomization is used to extend...

Standard methods for the analysis of linear latent variable models often rely on the assumption that the vector of observed variables is normally distributed. This normality assumption (NA) plays a crucial role in assessing optimality of estimates, in computing standard errors, and in designing...

Small sample properties are of fundamental interest when only limited data is avail- able. Exact inference is limited by constraints imposed by speci.c nonrandomized tests and of course also by lack of more data. These e¤ects can be separated as we propose to evaluate a test by comparing its...

Elasticities are often estimated from the results of demand analysis however, drawing inferences from them may involve assumptions that could influence the outcome. In this paper we investigate one of the most common forms of elasticity which is defined as a ratio of estimated relationships and...

This paper analyzes the quality of life over time in the U.S. In this paper we propose a statistical cluster analysis method based on an informationbased measure. This method is then employed to cluster diverse attributes of the quality of life. Aggregate annual measures of welfare are computed...

Matching estimators (Rubin, 1973a, 1977; Rosenbaum, 2002) are widely used in statistical data analysis. However, the large sample distribution of matching estimators has been derived only for particular cases (Abadie and Imbens, 2006). This article establishes a martingale representation for...

The regression discontinuity (RD) data design is a quasi-experimental design with the defining characteristic that the probability of receiving treatment changes discontinuously as a function of one or more individual characteristics. This data design occasionally arises in economic and other...

We investigate whether bonds span the volatility risk in the U.S. Treasury market, as predicted by most 'affine' term structure models. To this end, we construct powerful and model-free empirical measures of the quadratic yield variation for a cross-section of fixed-maturity zero-coupon bonds...
