We study the colonizing process of space by some populations which can be verbally described as follows: suppose a first incoming species occupies a random fraction of the available unit space. The forthcoming species takes an independent random fraction of the remaining space. There are n...

Given an n-tuple of independent processes, each converging at an exponential rate, conditions are given under which a cut-off occurs for the n-tuple, when the convergence is measured by different distances between probability distributions. More precise estimates and explicit examples are given...

En este trabajo extendemos el modelo neoclásico de Baxter y King (1993) para evaluar los efectos sobre el ciclo económico de dos reglas fiscales alternativas. Las reglas que analizamos son similares a aquellas implementadas en la práctica por algunos países, tales como limites al déficit...
