This paper gives a description of fertility influence on education level of population and its well-being. We carry out the consideration by a demographic model keeping age structure. We suppose that (i) a part of GDP ia used for investment in education, (ii) the production level depends on the...

Latin America suffer before each democratic election due to its structural clivage, high social inequity and demands. The objective of this paper is to show that at elections, for some importants countries, the contagion effects increase the correlation of the return series markets.

A key parameter that determines the distributional impacts of a policy shift in general equilibrium models is the elasticity of substitution between capital and labor. Despite the importance of this parameter in applied modeling, its identification continues to pose a challenge. Given the...

This paper explores the causes of deforestation and biodiversity loss in Guatemala and is organized into 4 parts. First, an overview about deforestation in Guatemala from 1950-2000 is provided, and the relationship between deforestation and biodiversity loss is explored. Secondly, some...

This paper presents a model of vehicle choice and empirically examines the risk posed by light trucks (sport-utility vehicles, vans, and pickups) to those that drive them and to other drivers, relative to the risk posed by cars. It compares the relative risk of dying and the relative crash...

Various methods were proposed to understand the linkages in an input- output system; however many focused only on the identification of key sectors in the economy. An alternative approach, identifying analytically importance of elements and combinations of elements was proposed as a field of...

There are three crucial mathematical system concepts in Finance, which are either being confused or misapplied - uncertainty, complexity and rank. First, the concept of epistemic uncertainty is sufficient for modeling and the concept of probability is unnecessary. This is illustrated by...

The least squares estimator is probably the most frequently used estimation method in regression analysis. Unfortunately, it is also quite sensitive to data contamination and model misspecification. Although there are several robust estimators designed for parametric regression models that can...
