In this work we afford the statistical characterization of a linear Stochastic Volatility Model featuring Inverse Gamma stationary distribution for the high frequency volatility. We detail the derivation of the moments of the return distribution, revealing the role of the Inverse Gamma law in...

Empirical processes for non ergodic data are investigated under uniform distance. Some CLTs, both uniform and non uniform, are proved. In particular, conditions for Bn = n^(1/2) (µn - bn) and Cn = n^(1/2) (µn - an) to converge in distribution are given, where µn is the empirical measure, an...

We analyse the academic performance of Italian students who graduated in 2004, and their occupational status and earnings in 2007. We find that the educational and occupational performances of male and female students do differ: girls outperform boys in academic achievement, but male graduates...

In Bayesian nonparametric inference, random discrete probability measures are commonly used as priors within hierarchical mixture models for density estimation and for inference on the clustering of the data. Recently it has been shown that they can also be exploited in species sampling...

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...

It is argued that, differently from a diffuse practice among modern economists, one needs reading more than the first couple of pages of the Wealth of Nations in order to fully appreciate Smith’s contribution to the economics of exchange, innovation and economic evolution. In particular, by...

Growth Diagnostics, GD, by Ricardo Hausmann, Dani Rodrik and Andrés Velasco, represents a useful and practical approach in order to identify the most binding constraints to explain low economic growth. According to the authors the full list of specific economic constraints is unknowable...

We propose a flexible prices model where endogenous market structures and search and matching frictions in the labor market interact endogenously. The interplay between firms endogenous entry, strategic interactions among producers and labor market frictions represents a strong amplification...
