The marginal cost of public funds defined as the ratio between the shadow price of tax revenues and the population average of the social marginal utility of income, is analysed within an explicit cost–benefit context. It is shown that for an optimal tax system the measure is always equal to...

In this paper we split up the sampling error occurred in stratified and clustering sampling, called global error and measured by the variance of estimator, in many partial errors each one referred to a single stratum or cluster. In particular, we study, for clustering sampling, the empirical...

As in many other countries, government policy in the UK has the objective of raising the participation rate of young people in higher education, while increasing the share of the costs of higher education paid by students themselves. A rationale for the latter element comes from evidence of a...

Equilibrium and tâtonnement in Walras' Eléments Franco Donzelli Abstract Two alternative interpretations of the equilibrium notion employed by Walras in the Eléments and related writings have been recurrently suggested in the literature: a "stationary" interpretation and an "instantaneous"...

Although past research has established the existence of strong social class effects on the decision to undertake higher education in the UK, there is only sparse empirical work investigating social class influences on the choice of degree subject at the undergraduate level. We estimate trinomial...

This paper contributes to the debate upon the trade-off between science and technology by looking at how the scientific performances of a researcher relate ex-ante to his/her attitude to patent, during his/her academic career. We run an event history analysis explaining the hazard for a...

Using an integrated model of purposive R&D activity and human capital accumulation, this paper analyses the joint impact that product market competition may exert on the sectoral distribution of skills and economic growth. In a framework where innovation takes place through an R&D technology...

Multiple Frame Survey has been originally proposed, according to an optimality approach, in order to persecute survey cost savings, especially in the case of a complete list available but expensive to sample. In the modern sampling practice it is frequent the case where a total and up-to-date...

In this paper we examine maximum likelihood estimation procedures in multilevel models for two level nesting structures. Usually, for fixed effects and variance components estimation, level-one error terms and random effects are assumed to be normally distributed. Nevertheless, in some...

We examine what determines differences across countries and over time in the distribution of personal incomes in the OECD. We first model the wage determination process and show that unemployment, the labour share, and the wage differential are all functions of labour market institutions. Next...
