Asymptotic and bootstrap tests are studied for testing whether there is a relation of stochastic dominance between two distributions. These tests have a null hypothesis of nondominance, with the advantage that, if this null is rejected, then all that is left is dominance. This also leads us to...

Income inequality can be measured at different levels of aggregation such as global, continental, international and national levels. Here we consider income inequality at regions defined as equivalent of continental and sub-continental levels. We investigate the economic disparity between...

This paper examines alternative forms of match bias arising from earnings imputation. Wage equation parameters are estimated based on mixed samples of workers who do and do not report earnings, the latter group being assigned earnings of donors who share some but not all the attributes of the...

We use spline interpolation to approximate the subjective cumulative distribution function of an economic agent over the future realization of a continuous (possibly censored) random variable. The method proposed exploits information collected using a small number of probability questions on...

We introduce the concept of a parameterized collection of games with side payments and determine a bound on e so that all sufficiently large games in such a collection have non-empty e -cores. A parameterized collection of games is described by (a) the number of approximate player types and the...

Structural equation models (SEM) are commonly used to analyze the relationship between variables some of which may be latent, such as individual ``attitude'' to and ``behavior'' concerning specific issues. A number of difficulties arise when we want to compare a large number of groups, each with...

Connections between Statistics and Archaeology have always appeared very fruitful. The objective of this paper is to offer an outlook of some statistical techniques that are being developed in the most recent years and that can be of interest for archaeologists in the short run.

The dynamics of employment in final services depends on a set of economic, social and cultural factors. On the other hand, the increase in the population incomes (and the influence of some national factors) leads to an increase in the demand for services. However, the relatively poor...

The present study approaches the dynamic correlation between GDP and the gross fixed capital formation, based on the use of ICOR (incremental capital output ratio) indicator in order to determine the required investment volume for the period 2005-2008, under various efficiency conditions,...

This paper studies the extent of rent sharing in the Italian metal- mechanical industry by analyzing separately what occurs at each stage of wage negotiations. In particular, we evaluate how, through the bargaining process, aggregate and idiosyncratic productivity shocks influence respectively...
