The conventional Wilcoxon/Mann-Whitney test can be invalid for comparing treatment effects in the presence of missing values or in observational studies. This is because the missingness of the outcomes or the participation in the treatments may depend on certain pre-treatment variables. We...

Partial least squares-based path modeling with latent variables is a methodology that allows to estimate complex cause-effect relationships using empirical data. The assumption that the data is collected from a single homogeneous population is often unrealistic. Identification of different...

Ethnic diversity and provision of public goods have long been understood to share a negative relationship. While there has been a concerted effort to define and measure ethnic diversity around the world, we are interested in analyzing the possible differences in these measures when it comes to...

The aim of this paper is to inquire into the possible relation between the FTAA (Free Trade Area of Americas) and the progressive interna- tionalization of the Euro. We will sustain that the actual productive situation (globalization) makes impossible to think of an FTAA with- out a kind of...

Measuring migrants’ integration into host societies is a challenging task as, in general, measuring any social behavior and social phenomena. The task is affected by many specific problems related to the definition of the objective of study and the impact of subjective evaluations in the...

In this paper I propose a nonstandard t-test statistic for detecting level and trend breaks of I(0) series. Theoretical and limit-distribution critical values obtained from Montecarlo experimentation are supplied. The null hypothesis of anthropogenic versus natural causes of global warming is...

The important step in the design of a cellular manufacturing (CM) system is to identify the part families and machine groups and consequently to form manufacturing cells. The scope of this article is to formulate a multivariate approach based on a correlation analysis for solving cell formation...

The question whether the European Monetary System has brought about a reduction in the variability of its members' exchange rates is not a trivial issue since central rates are adjustable and bilateral exchange rates are allowed to move freely within fairly large margins. In this paper I have...

This paper examines the link between financial openness and financial development through panel data analysis on advanced and emerging market countries. Using indices, financial openness together with institutional and educational variables explains a large part of the variation in financial...
