The conversion problem on the metric scale of the judgments expressed towards the products or the services can be solved searching the latent variable, that is always the normal standard. Sometimes, particularly when the frequencies are concentrated on the left extreme or the right extreme of...

The aim of this paper is to analyze the wage differentials associated with non-pecuniary working conditions (distance to job, environment conditions, working times) using objective and subjective data. In fact, the individual can be compensated for unsatisfactory working conditions by higher...

It has been empirically observed that correlation matrices of forward interest rates have the first three eigenvalues which are simple and their corresponding eigenvectors, termed as shift, slope and curvature respectively, with elements presenting changes of sign in a regular way. These...

Since Solow’s (1957) contribution, human capital has a central role in the debate on economic growth as a leading long period development factor. If from a theoretical point of view the role of human capital on economic growth both directly and throughout its use in R&D activities is fully...

Le opzioni di politica economica pongono il management di un Parco Scientifico e Tecnologico PST) di fronte al trade-off tra una politica di incentivo all’entrata di nuove imprese (r-policy) e una di accrescimento e valorizzazione delle risorse presenti attraverso una selezione dei nuovi...

The aim of this work is to present a Matlab implementation of different methods for estimating the term structure of interest rate. More precisely, we implement the exponential functional form of Nelson-Siegel and polynomial spline methods (with or without penalty term), considering both coupon...
