Given a scalar random variable Y and a random vector X defined on the same probability space, the conditional distribution of Y given X can be represented by either the conditional distribution function or the conditional quantile function. To these equivalent representations correspond two...

This paper looks at the relationship between the institutional design of the social security system and retirement from the labour force in three countries: Italy, Spain and the USA. Our works stresses the importance of dynamic incentives embedded in social security systems throughout the world...

In this paper I review evidence on the long-run relation between height and economic development in Italy. I ask three questions: What are the long-run trends of mean height and real incomes in Italy? What do we know about height dispersion? What other aspects of the distribution of height...

We consider a general sample selection model where unit and item nonresponse simultaneously affect a regression relationship of interest, and both types of nonresponse are potentially correlated. We estimate both parametric and semiparametric specifications of the model. The parametric...

We investigate the relationship between ageing, cognitive abilities and retirement using the Survey on Health, Ageing and Retirement in Europe (SHARE), a household panel that offers the possibility of comparing several European countries using nationally representative samples of the population...

A common problem in applied regression analysis is that covariate values may be missing for some observations but imputed values may be available. This situation generates a trade-off between bias and precision: the complete cases are often disarmingly few, but replacing the missing observations...

Unlike the value at risk, the expected shortfall is a coherent measure of risk. In this paper, we discuss estimation of the expected shortfall of a random variable Yt with special reference to the case when auxiliary information is available in the form of a set of predictors Xt. We consider...

A "good" pension reform should address a number of issues. One important aspect is the financial soundness of the system, particularly in the light of the legacy that we leave to future generations. Policy makers should also address economic efficiency at two levels: no waste of resources for a...

This paper studies convergence in per-capita GDP across European regions over the period 1980-2000. We use median unbiased estimators of the rate of convergence to the steady-state growth path, while allowing for unrestricted patterns of heterogeneity and spatial correlation across regions. By...
