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 lay an...

The definition of vectors of dependent random probability measures is a topic of interest in applications to Bayesian statistics. They, indeed, represent dependent nonparametric prior distributions that are useful for modelling observables for which specific covariate values are known. In this...

Move-to-front rule is a heuristic updating a list of n items according to requests. Items are required with unknown probabilities (or ppopularities). The induced Markov chain is known to be ergodic [4]. One main problem is the study of the distribution of the search cost defined as the position...

The paper proposes a new nonparametric prior for two dimensional vectors of survival functions (S1, S2). The definition we introduce is based on the notion of L´evy copula and it will be used to model, in a nonparametric Bayesian framework, two sample survival data. Such an application will...

Using a panel of administrative Italian data (source: INPS), this paper provides new empirical evidence on the earnings mobility in Italy over a relatively long time period (1985-1996). Transition matrices have been used to document the extent to which Italian employees change their position in...

A higher job creation is a common result by many theoretical approaches trying to model marginal labor market reforms. In the framework proposed by Berton and Garibaldi [2006], in particular, the equilibrium arrival rate of temporary job offers is expected to be higher than the arrival rate of...

The liberalization of fixed term contracts in Europe has led to a two tier regime, with a growing share of jobs covered by temporary contracts. The paper proposes a matching model with direct search in which temporary and permanent jobs coexist in a long run equilibrium. When temporary contracts...

We use a unique data set providing administrative information on earnings by skill-level (blue collars, white collars), on the local stock of human capital and on several firm’s characteristics, including balance sheet data, to investigate the size of localized human capital externalities in...
