Motivated by classification issues that arise in marine studies, we propose a latent-class mixture model for the unsupervised classification of incomplete quadrivariate data with two linear and two circular components. The model integrates bivariate circular densities and bivariate skew normal...

Tooth Cementum Annulation (TCA) is an age estimation method carried out on thin cross sections of the root of human teeth. Age is computed by adding the tooth eruption age to the count of annual incremental lines that are called tooth rings and appear in the cementum band. Algorithms to denoise...

We estimate a Cox proportional hazards model where one of the covariates measures the level of a subject´s cognitive functioning by grading the total score obtained by the subject on the items of a questionnaire. A case study is presented where the sample includes partial respondents, who did...

We examine whether and to what extent political institutions explain different performances in income redistribution across countries. In particular, we first review available sources of data and measures of income redistribution, discussing the pros and cons of each one. Second, we outline a...

Empirical tests of the theories on the relationship between political competition and economic performance generate a puzzle: data tend to support the theory at the lower levels of government, but not in panels of countries. We argue that the larger set of policy instruments reduces the tax...

Understanding corruption is at the heart of treating the dysfunctionality of many countries' public sectors. Yet, most corruption research suffers from one common problem: There is no "objective" measure of public-sector corruption for a cross-section of countries. Most studies on the...

This paper has two goals. 1) To evaluate the sustainability of Italian public deficits according to the methodology developed by Trehan and Walsh (1988, 1991) and Bohn (2004); 2) To analyze how the determinants of debt creation evolved in the years following the Maastricht Treaty and how this...

This paper analyses intergovernmental transfers in France and Italy to assess how soft budget spending behaviors may result from slacks in institutional constraints or from phenomena related to political culture, like administrative practices or implementation of rules. It innovates on the...
