We extend the classical local Whittle estimation procedure to fractionally integrated I(d) processes, where d-3/2, thus covering stationary and non-stationary regions. Asymptotic properties of the bias of the estimator are investigated. It is shown that in a wider region than previously...

This paper deals with estimation and hypothesis testing in stationary and nonstationary models with a linear trend. Using semiparametric estimators, we obtain asymptotic confidence intervals for mean, trend, and memory parameters. The confidence intervals are applicable for a wide class of...

We propose a class of statistics where the direction of one of the alternatives is incorporated. We modify a class of multivariate tests with elliptical confidence regions, not necessarily arising from normal-based distribution theory. The resulting statistics are easy to compute, they do not...

We deal with the important question of estimating the long-run variance of a stationary sequence. We derive the asymptotic properties of a generalized Newey-West type of estimator in the case of a linear I(d) process. The results show that the bias and asymptotic distribution of the generalized...

The remarkable growth of older population has moved long term care to the front ranks of the social policy agenda. Understanding the factors that determine the type and amount of formal care is important for predicting use in the future and developing long-term policy. In this context we jointly...

It is evaluated that, each year, 35% out of the 10 million hospital admissions in Italy take place outside the LHAs of residence. In our paper we try to give an explanation of this phenomenon making reference to the social gravity model of spatial interaction. We estimate gravity equations using...

This paper considers a regression model with a log-transformed dependent variable. The log transformed model is estimated by simple least squares, but computing the conditional mean of the dependent variable on the original scale given the explanatory variables analytically requires knowing the...

Internationally comparable panel data from the full eight waves of the ECHP are used to study the effects of health on retirement in nine EU countries. Self-reported retirement is compared to a broader measure of inactivity. Measures of health include two latent stock measures, one that is...

This paper introduces a new approach to measuring the association between health and socioeconomic status. Measuring inequalities in health is difficult when health is measured qualitatively, specifically on an ordinal scale. This paper demonstrates a rank-based dependence measure - the copula -...

The main goal of Seguro Popular is to improve the financial protection of the uninsured population against excessive health expenditures. Seguro Popular (SP) covers a variety of preventive and curative procedures, as well as medicines, and hospital care for the poorest segment of the Mexican...
