We propose a flexible stochastic framework for modeling the market share dynamics over time in a multiple markets setting, where firms interact within and between markets. Firms undergo stochastic idiosyncratic shocks, which contract their shares, and compete to consolidate their position by...

The study of properties of mean functionals of random probability measures is an important area of research in the theory of Bayesian nonparametric statistics. Many results are known by now for random Dirichlet means but little is known, especially in terms of posterior distributions, for...

An important issue in survival analysis is the investigation and the modeling of hazard rates. Within a Bayesian nonparametric framework, a natural and popular approach is to model hazard rates as kernel mixtures with respect to a completely random measure. In this paper we provide a...

The present paper provides a review of the results concerning distributional properties of means of random probability measures. Our interest in this topic has originated from inferential problems in Bayesian Nonparametrics. Nonetheless, it is worth noting that these random quantities play an...

In this paper I provide estimates of the impact of immigration on native wage and employment levels (rather than on wage inequality which has been the focus of the literature). I use variation within 2-digit industries across regions using Austrian panel data from 1986 to 2004 for...

We show that increasing the probability of obtaining a job offer through the network should raise the observed mean wage in jobs found through formal (non-network) channels relative to that in jobs found through the network. This prediction also holds at all percentiles of the observed wage...

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...

Administrative data from INPS (Italian Institute for Social Security) on Italian high tenure workers job-histories (15 years, from 1985 to 1999) is used to quantify the temporal pattern of the effect of displacement on workers’ earnings, employment and wages. Moreover, I distinguish different...
