It is known that time-weighted charts like EWMA or CUSUM are designed to be optimal to detect a specific shift. If they are designed to detect, for instance, a very small shift, they can be inefficient to detect moderate or large shifts. In the literature, several alternatives have been proposed...

Mortality data provide valuable information for the study of the spatial distribution of mortality risk, in disciplines such as spatial epidemiology, medical demography, and public health. However, they are often available in an aggregated form over irregular geographical units, hindering the...

Some groups of countries are connected not only economically, but also social and even demographically. This last fact can be exploited when trying to forecast the death rates of their populations. In this paper we propose a hierarchical specification of the Lee-Carter model and we assume that...

This paper proposes a recursive procedure that characterizes the order of the pole and the coecients of the Laurent series representation of the inverse of a regular analytic matrix function. The algorithm consists in performing a finite sequence of rank factorizations of matrices of...

This paper contributes to the ongoing debate on the prevalence and determinants of Living Apart Together (LAT) relationships by focusing on two contrasting family settings such as France and Italy. First, corroborate the view that being “single” in residential terms does not mean being...

This paper estimates the causal impact of investment in information andcommunication technologies (ICT) on student performances in mathematics asmeasured in the Program for International Student Assessment (PISA) 2012 for Spain.To do this we apply a new methodology in this context known as...

In this paper we analyze the yield difference between two on- and off-the-run similar notes to gauge the liquidity premium. We investigate this issue by relating such a differential to several liquidity indicators that we build and examine -to our knowledge for the first time- throughout the...

In this paper we model macroeconomic instability as the outcome of the dynamical interaction between debt accumulation and the “state of confidence” in a small open economy with a super-fixed exchange rate arrangement. Our analysis is set in a theoretical framework where balance-sheets...

In the context of functional data analysis, we propose a new method to test the homogeneity of families of functions. Based on some well-known depth measures, we construct four different statistics in order to measure distance between the two families. A simulation study is performed to check...

We estimate a stochastic frontier model with random inefficiency parameters, which allows us not only to identify the role of bank risk-taking on driving cost and profit inefficiency, but also to recognize heterogeneous effects of risk exposure on banks with different characteristics. We account...
