Research review for effects of investment on polarization of wealth

Abstract

In South Korea, the polarization of wealth is very serious, and its pace is faster than in other countries. Recently, investments in instruments such as stocks, bitcoins and in real estate are seen as decisive factors that intensify the polarization of wealth in South Korea. The motivation for this study is to analyze effects of investment on polarization of wealth. We carried out a study focused on the impact of investments on the polarization of wealth. In this study, we analyzed the effect of investment on the polarization of wealth. We studied the effect of real estate, stocks, and bitcoin on the polarization of wealth. We conducted multiple regression analysis on the income quintile share ratio, real estate, stocks, and bitcoins and then carry out multiple regression analysis with interest rates, household debt, incomes, and price indices. In order to analyze the investment impact on the polarization of wealth, the public data (2015–2020) from the government and institutions were utilized. Results showed that real estate, stocks, and bitcoins set as investment instruments in this study did not have a significant impact on the polarization of wealth. It is because the popularity of investments in real estates, stocks, and bitcoins in South Korea began in earnest from 2020, and has actually accelerated the polarization of wealth. This study has the theoretical contribution because the impact of investments on the polarization of wealth is analyzed, and policies for economic stability are discussed and presented. In addition, a new academic contribution of this study is to analyze the investment and polarization of wealth at the same time.
