In South Korea, conservatism and progressivism were formed under major political and socioeconomic challenges since the establishment of the country in 1948. Moreover, the intensifying ideological polarization between conservatives and progressives since 2010 is discussed. Considering that these ideological terms were developed while overcoming national challenges, it is highly likely that deepening ideological polarization is related to the new challenge of economic inequality, which became rampant at the time. This article argues that the Korean government's measures to address inequality have affected ideological polarization. Specifically, the development of conservatism and progressivism in the Korean context are discussed and conservative governments' market‐oriented policies and progressive governments' policies to address inequality are examined. Conservatism expanded during this process while progressivism strengthened, which was critical to the deepening of ideological polarization. Finally, the implications of this study are discussed.

This essay reviews the policy‐oriented literature on economic inequality in wealthy countries published from 2008 to 2018. We focus on this decade because it is a period bookended by both the beginnings of the Great Recession of 2008–2009 as well as the recovery. During this timeframe, attention to inequality by social policy scholars grew substantially, which we argue reflects an interest in both inequality trends as well as redistributive social policy. We observe in the literature sustained efforts to understand both the relationship between social policy and economic inequality, as well as determinants of changes to redistributive social policy. We also note substantial variation in research traditions, as well as opportunities to address substantive, methodological, and theoretical gaps. Our review summarizes the approaches and findings from the literature and discusses the implications of the findings for the study of economic inequality within the academic field of public policy.

This paper reviews theoretical and empirical approaches drawn from influential journal articles and books on sustainability policy published over the last 10 years (2007 through 2017). Due to the widespread application of sustainability as a concept and space limitations, the paper more narrowly focuses on sustainability research in three critical policy areas: climate change, urban development, and agroecology and food systems. Drawing from information provided primarily by citation indexes, the study identifies and analyzes the research literature related to sustainability in these three fields. Future theoretical and empirical research approaches that can better integrate and connect the current diffuse and incongruent literature on sustainability are discussed in the paper. The findings of the literature review generate a number of possible future research directions that are discussed in the study. [ABSTRACT FROM AUTHOR]

One of the most important economic trends of the past 30 years has been the escalating levels of within-country income inequality. Much of the developed world is currently experiencing large increases in income inequality. Indeed, income inequality in the United States now exceeds the previous highs of the 1930s. Recent research has found that increases in income inequality can produce a wide variety of societal ills. This article examines the effects of economic inequality on educational outcomes. Drawing on data provided by the World Bank and the Organisation for Economic Co-operation and Development (OECD) from 2000 through 2015, we find that a country’s level of economic inequality has large, negative effects on its student academic achievement. The effect sizes are largest in math. We examine a variety of potential solutions to lessen within-country economic inequality. [ABSTRACT FROM AUTHOR]
