It is known that, when in the linear regression model there is a high degree of multicollinearity, the results obtained by using the Ordinary Least Squares (OLS) method are unstable. As a solution to this situation, in this paper we present the raised method, the ridge method and the orthogonal...

Migration movements in the south border of México with Guatemala, has motivated serious social, economic and politic un-stability in both countries. During the last decades of the XX-th century, the sites of the south zone have become in zones with high violence indexes, delinquency and...

It is implausible that the spread of Covid-19 has not had an impact on entrepreneurship in Peru, considering that on average 41.1 % of the Economically Active Population is engaged in starting their own businesses. The objectives of this research are as follows: To estimate the influencing...

Despite their vigorous expansion in the last 30 years in the field of econometrics, spatial models are still not widely disseminated in the empirical literature in Argentina focused on quantitative aspects of regional scope. This paper aims to present the central lines of spatial econometric...

This research shows the pay gap between public entities in Ecuador. We use the information of Annex Relation Unit of the Internal Revenue Service and the Civil Registry for 2008 and 2009. The study makes a Mincerian model and an analysis by quintiles to find and compare the wage gap between...

Econometrics is the area of statistics concerned in analyzing economic data, for both economic and business applications. This document, introduces the intermediate concepts of this area, for students already familiarized with basic econometric theory. In particular, topics concerning...

In spatial econometrics, it is customary to specify a weighting matrix, the so-called W matrix. The decision is important because the choice of W matrix determines the rest of the analysis. However, the procedure is not well defined and, usually, reflects the priors of the user. In the paper, we...

Spatial econometrics is a relatively young branch econometric but with a great growth in the last decades. The complexity of spatial analysis and the estimation of spatial models has been the major obstacle for applied studies. The aim of this paper is to contribute to the diffusion of spatial...
