Evidence of the existence of overeducation in the Spanish labour market has drawn the attention of research on the transitory character of overeducation (Alba-Ramirez, 1993 and García and Malo, 1995). Our main interest lies on whether overeducation is a source of inefficiency in the allocation...

We study the processes for the conditional mean and variance given a specification of the process for the observed time series. We derive general results for the conditional mean of univariate and vector linear processes, and then apply it to various models of interest. We also consider the...

We investigate several important inference issues for factor models with dynamic heteroskedasticity in the common factors. First, we show that such models are identified if we take into account the time-variation in the variances of the factors. Our results also apply to dynamic versions of the...

In the context of time series regression, we extend the standard Tobitmodel to allow for the possibility of conditional heteroskedastic error processes of the GARCH type.We discuss the likelihood function of the Tobit model in the presence of conditionally heteroskedastic errors.Expressing the...

Simulation estimators, such as indirect inference or simulated maximum likelihood, are successfully employed for estimating stochastic differential equations. They adjust for the bias (inconsistency) caused by discretization of the underlying stochastic process, which is in continuous time. The...

The analysis of the determinants of the individual wage income can be transfered to the total domestic income from the point of view of the human capital. This paper analyzes the effects that a group of variables, relative to sociodemographic and labour attributes, exerts on the total income...

This paper carries out a household classification in the framework of the Social Accounting Matrix. Bearing in mind the enlargeinent proposals of the National Accounts System of the United Nations, a first classification of Spanish households in accordance with certain demographic...

We deal with the problem of decomposing a time series into the sum of unobserved components as in detrending or seasonal adjustment. In particular, we analyze the situation in which the decomposition into orthogonal balanced components as performed by the ARIMA-Model-Based method is...

This paper implements the conceptual framework sketched by Pyatt (1990) to construct an extended Social Accounting Matrix for Spain in 1995 (ESAM-95) to consider, in addition to the market economy, the production of services provided by households through unpaid work. In doing so, the ESAM-95...
