In this note I explictly construct utility functions that (more or less) satisfy the conditions needed for the counterexample of Mas-Colell and Zame(1992)

This book covers a broad range of mathematical and statistical concepts that includes Mathematical Statistics, Non-Parametric Statistics, Design of Experiments, Probability, Operations Research, and Stochastic Models. The topics covered include: statistics, stochastic models, mathematics,...

After a characterization of the cost-oriented assembly line balancing problem it will be shown that by loading the stations maximally the cost-oriented optimum can be missed. Instead of loading the stations maximally the criterion two-stations-rule a has to be used. For generating optimal...

The particular subject of this paper, is to give an explicit formulas that will permit to obtain the linear VaR or Linear ES, when the joint risk factors of the Linear portfolios, changes with mixture of t-Student distributions. Note that, since one shortcoming of the multivariate t-...

The demographic transition that swept the world in the course of the last century has been identified as one of the prime forces in the transition from stagnation to growth. The unprecedented increase in population growth during the early stages of industrialization was ultimately reversed and...

The proposition that trade causes economic growth has enriched international economic theory. Even so, how best to estimate and test for the effects of trade on economic growth remains a challenge to-date, mainly because of the joint determination of the empirical measures of both trade and...

Pagan and Shannon's (1985) widely used approach employs local linearizations of a system of non-linear equations to obtain asymptotic distributions for the endogenous parameters (such as prices) from distributions over the exogenous parameters (such as estimates of taste, technology, or policy...

It's commonly known that the correlation between stocks increases during market turbulent periods. In this work we propose a modellization of this feature, viewed as a collective effect, rearranging a toy-model first proposed in 2001. Equities are modelled as quasi random walk variables, where...

We explore commons problems when agents have access to capital markets. The commons has a high intrinsic rate of return but its fruits cannot be secured by individual agents. Resources transferred to the capital market earn lower returns, but are secure. In a two period model, we assess the...
