    Volatility-related exchange traded assets: An econometric investigation


    We compare Semi-Nonparametric expansions of the Gamma distribution with alternative Laguerre expansions, showing that they substantially widen the range of feasible moments of positive random variables. Then, we combine those expansions with a component version of the Multiplicative Error Model to capture the mean reversion typical in positive but stationary financial time series. Finally, we carry out an empirical application in which we compare various asset allocation strategies for Exchange Traded Notes tracking VIX futures indices, which are increasingly popular but risky financial instruments. We show the superior performance of the strategies based on our econometric model.

    Fast ML estimation of dynamic bifactor models: An application to European inflation


    We generalise the spectral EM algorithm for dynamic factor models in Fiorentini, Galesi and Sentana (2014) to bifactor models with pervasive global factors complemented by regional ones. We exploit the sparsity of the loading matrices so that researchers can estimate those models by maximum likelihood with many series from multiple regions. We also derive convenient expressions for the spectral scores and information matrix, which allows us to switch to the scoring algorithm near the optimum. We explore the ability of a model with a global factor and three regional ones to capture inflation dynamics across 25 European countries over 1999-2014.

    Leaving home with a partner


    Leaving the parental home is often a decision made together by two people. In this paper we present a theoretical model analyzing moving out as a joint decision and then test its implications using a new dataset of university graduates collected in the southern Spanish region of Murcia in 2004-2006, which includes information on partners and their parents. In equilibrium we find some evidence of the importance of assortative mating in moving out. Studying partnership, work, and moving out decisions simultaneously we obtain that the latter depend positively on own human capital and they are affected differently by maternal and paternal characteristics and with different effects on men and women.
