Inequality is it a result of globliazation?

This paper reviews the trends for the period 1980-2015 of some of the main macroeconomic variables of the countries of
greater interest of our sample and investigates the determinants influencing the variance of the Gini coefficients as representative of
inequality measurement. The empirical results observed when comparing the results of the regression modelling obtained one clear
conclusion can be drawn: the two determinants that are significant for all three country groups are Population and Globalization.
Population has a positive effect in increasing inequality of income distribution for all of them, whereas globalization has only a
positive effect in European countries and emerging countries, but with a big impact over the same, but in the United States in has a
negative effect, reducing inequality levels of income distribution. The question regarding the decisions of the UK and the USA of
adopting protectionist measures, and if it is a good idea is answer it terms of globalization and income distribution inequality finding
that it would be a positive decision for the UK and a negative one for USA.
