This paper considers a class of semiparametric estimators that take the form of density-weighted averages. These arise naturally in a consideration of semiparametric methods for the estimation of index and sample-selection models involving preliminary kernel density estimates. The question...

Using linked employer-employee data from the German Structure of Earnings Survey 2001, this paper provides a comprehensive picture of the wage structure in three wage-setting regimes prevalent in the German system of industrial relations. We analyze wage distributions for various labor market...

Using kernel density estimation we find that over their 1990s business cycles the entire distribution of after-tax (disposable) income moved to the right in the United States and Great Britain while inequality declined. In contrast, Germany and Japan experienced less growth, a rise in inequality...

This paper presents an analysis of changes in the distribution of gross household income and income inequality over the period 1983–1998. The analysis applies a semiparametric approach to study the effects of changes in the distribution of household types, and changes in National...

Abstract Consider the regression problem with a response variable Y and with a d -dimensional feature vector X . For the regression function m(x)  = E{ Y|X  =  x }, this paper investigates methods for estimating the density of the residual Y  −  m(X) from independent and identically...

Gaussian mixtures (i.e. linear combinations of multivariate Gaussian probability densities) appear in numerous applications due to their universal ability to approximate multimodal probability distributions. Finding the modes (maxima) of a Gaussian mixture is a fundamental problem arising in...

This article uses Data Envelopment Analysis (DEA) in order to determine the performance levels of 16 departments of a public owned university. Particularly, the constant returns to scale (CRS) and variable returns to scale (VRS) models have been applied alongside with bootstrap techniques in...

This paper examines how living standards in India have improved over two decades, focusing on the distribution of household-level consumption expenditures. The analysis is conducted using the DiNardo-Fortin-Lemieux (DFL) semi-parametric decomposition method. This method offers two desirable...

El objetivo del presente documento es presentar un diagnóstico de los aspectos socioeconómicos más importantes de la capital, principalmente en la primera década del siglo XXI. Bogotá se ha consolidado como la metrópoli más exitosa del país en varios aspectos, que pueden ser resumidos en...

This paper proposes a computational-statistics based approach for solar radiation reconstruction at sub-hourly intervals. A dimensionless form of stochastic variable, V, which is defined as the difference between the theoretical global solar radiation in clear-sky conditions and the actual solar...
