The income and wealth distribution are fundamental variables on understanding social and economic inequality. This article analyses causes we consider relevant of the increase in economic inequality and world wealth concentration. It approaches the impact of economic globalization, in the context of trade and financial integration, and effects of technological change and evolutions in the field of labor market. If globalization and technological change were long considered crucial drivers of inequality trends in different countries, over different decades, for economic inequality many studies are now documenting the importance of changes in various markets. Also, the author tries to examine the interplay of these factors on distribution and creating gaps on wealth between countries.
