Gwangeun Choi presented the paper, “The Link between Economic and Political Inequality in Cross-National Perspective” at the Politics and Inequality conference held in Warsaw, Poland in December 2018.
Dr. Choi recently received a PhD in Government at the University of Essex in the UK. His research interests are in the areas of democracy, quality of democracy, political inequality, economic inequality, perceived inequality, redistributive preferences, redistribution, and universal basic income. His latest article, “Revisiting the Redistribution Hypothesis with Perceived Inequality and Redistributive Preferences” appeared at the European Journal of Political Economy (2019).
We asked Gwangeun Choi for an extended abstract of his Politics and Inequality conference paper and, via email, some questions about his research. We are thankful for his positive and detailed response.
Extended Abstract by Gwangeun Choi
It is widely believed that there exists a debilitating feedback cycle linking economic and political inequality. However, there has been a lack of empirical evidence about this association, particularly, in cross-national comparative research. It is largely because cross-national measures of political inequality are underdeveloped. To fill this gap, this study introduces the Political Inequality Index (PII) and the Political Power Inequality Index (PPII). The PII is composed of the two dimensions: participation and representation, which are based on the reconceptualization of political inequality from the perspective of a middle-range conception. The PPII comes from the indicators that measure the distribution of political power across socioeconomic position, social group, and gender, which the Varieties of Democracy provides. This inquiry then investigates the two-way causal relationship between economic and political inequality. In the first causal direction, net income inequality is used as a proxy for economic inequality, while in the reverse causal linkage political inequality is supposed to influence market income inequality and redistribution separately, as income inequality is considered as an outcome of the two different distributive stages. In doing so, both causal directions between economic and political inequality are integrated into a unified framework. With respect to estimation techniques, a system GMM estimator for a dynamic panel data model, which is an increasingly popular estimation method, is mainly used to address the issue of endogeneity. The findings show that net income inequality does not significantly affect political inequality and that political inequality appears to have little impact on market income inequality, while political inequality seems to contribute to economic inequality by influencing redistribution in a negative direction.
The research you presented at the Politics and Inequality conference was on the relationship between political inequality and economic inequality in cross-national perspective. How did you get interested in this topic? And how is this topic connected to other research that you are doing?
I first became interested in a concept ‘political equality’ while I was doing research on the quality of democracy. In my framework designed to conceptualize and measure the level of democracy, political equality was one of the three core principles of democracy. Thus, it was easy for me to construct a new measure of political inequality, building on this framework. The next step was to investigate the reciprocal relationship between economic inequality and political inequality, as I realized that there is a lack of empirical evidence on this linkage although no one seems to doubt the widespread belief of the vicious cycle between economic and political inequality.
What is most challenging about measuring political inequality, and why?
I think that the most challenging part is to provide convincing theoretical arguments on the conceptualization of political inequality. Measuring the quality of democracy is also faced with the same issue. My study on democracy and political inequality and several other studies attempting to measure them with relatively thick concepts reached a consensus in excluding both minimalist and maximalist approaches. However, this does not guarantee that the majority of scholars agree with a specific middle-range concept of democracy or political inequality. This is therefore a more pressing issue than a range of measurement problems.
