We consider a model in which educational investments entail productivity gains, signaling power, and social returns. The latter depend on the relative position the agent occupies in one of three di¤erent dimensions: (i) his innate characteristics, (ii) his level of schooling, and (iii) his...

Paths to adulthood have changed greatly in the last decades: entries into the labour market as well as into partnership or parenthood have been postponed, with also new sequences and interconnections. In this piece of work we observe life-courses from the ages of 14 to 35 of men and women born...

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

This article investigates the relationship between educational attainment, in terms of both level and field of education, and the probability of being childless in Spain. Findings demonstrate that there is a significant difference in childlessness by education level among women aged 34-50, while...

Most Oecd Countries are experiencing a rapid population ageing. Italy adds to this picture a very low labour market participation of the elders, so that most projections of the impact of ageing on the labour market are rather pessimistic. However, there are other long run modifications currently...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...

Time-changed Brownian motions are extensively applied as mathematical models for asset returns in Finance. Time change is interpreted as a switch to trade-related business time, different from calendar time. Time-changed Brownian motions can be generated by infinite divisible normal mixtures....
