Una de las características de los datos de renta procedentes de las Encuestas de Presupuestos Familiares es su escasa fiabilidad, ya que los hogares entrevistados ocultan parte de ella. Recientemente, Pena, Callealta, Casas, Merediz y Núñez (1996) han propuesto una metodología para corregir...

The modelling of technical progress in a production economy is a problem of great interest. Non-parametric approximation of technical progress through the use of an adaptively fitted spline function is presented as an attractive solution. An application demonstrates the sensitivity of estimates...

A series of properties of the distribution of income and aggregated expenditure on goods and services has been postulated by W. Hildenbrand (1994) and others to hold. In this paper we infer on these properties from the Spanish Family Budget Survey (EPF) of the years 1973, 1980, 1990, using...

Nawata [8–10] proposed a new estimator for the standard regression, censored regression, and binary choice models, based on grouping of observations. This paper shows that Nawata's grouping method can be generalised to various types of estimation problems and represents a new class of...

This paper presents a robust estimation of two income distribution models using Spanish data for the period 1990-91 under three different concepts of income. The effect on the estimates of the Theil index due to the choice of the definition of income and of the estimation method is also analysed.

Unemployment durations are generally modelled by specifying the conditional probability of leaving unemployment (the hazard function). Existing studies for Britain all use very restrictive parametric specifications of the hazard function, mostly commonly Weibull in form. These restrictions...
