Who votes for whom and why? Why has growing inequality in many parts of the world not led to renewed class-based conflicts, and seems instead to have come with the emergence of new divides over identity and integration? News analysts, scholars, and citizens interested in exploring those questions inevitably lack relevant data, in particular the kinds of data that establish historical and international context. Political Cleavages and Social Inequalities provides the missing empirical background, collecting and examining a treasure trove of information on the dynamics of polarization in modern democracies. The chapters draw on a unique set of surveys conducted between 1948 and 2020 in fifty countries on five continents, analyzing the links between voters’ political preferences and socioeconomic characteristics, such as income, education, wealth, occupation, religion, ethnicity, age, and gender. This analysis sheds new light on how political movements succeed in coalescing multiple interests and identities in contemporary democracies. It also helps us understand the conditions under which conflicts over inequality become politically salient, as well as the similarities and constraints of voters supporting ethnonationalist politicians like Narendra Modi, Jair Bolsonaro, Marine Le Pen, and Donald Trump.

Brahmin Left versus Merchant Right: Changing Political Cleavages in 21 Western Democracies, 1948-2020

Amory Gethin, Clara Martínez-Toledano, Thomas Piketty

Quarterly Journal of Economics, Volume 137, Issue 1, Pages 1–48, February 2022. Editor's choice.

 

This article sheds new light on the long-run evolution of political cleavages in 21 Western democracies. We exploit a new database on the socioeconomic determinants of the vote, covering over 300 elections held between 1948 and 2020. In the 1950s and 1960s, the vote for social democratic, socialist, and affiliated parties was associated with lower-educated and low-income voters. It has gradually become associated with higher-educated voters, giving rise in the 2010s to a disconnection between the effects of income and education on the vote: higher-educated voters now vote for the “left,” while high-income voters continue to vote for the “right.” This transition has been accelerated by the rise of green and anti-immigration movements, whose distinctive feature is to concentrate the votes of the higher-educated and lower-educated electorates. Combining our database with historical data on political parties’ programs, we provide evidence that the reversal of the education cleavage is strongly linked to the emergence of a new “sociocultural” axis of political conflict.

Why is Europe More Equal than the United States?

Thomas Blanchet, Lucas Chancel, Amory Gethin

American Economic Journal: Applied Economics, forthcoming.

This article combines all available survey, income tax, and national accounts data to produce pretax and posttax income inequality series in twenty-six European countries from 1980 to 2017. Our estimates are consistent with macroeconomic growth rates and comparable with US distributional national accounts. Inequality grew in nearly all European countries, but much less than in the US. This rise was concentrated at the top end of the income distribution and was most pronounced in Eastern Europe. Contrary to a widespread view, we demonstrate that Europe’s lower inequality levels cannot be explained by more equalizing tax-and-transfer systems. After accounting for indirect taxes and in-kind transfers, the US redistributes a greater share of national income to low-income groups than any European country. “Predistribution”, not “redistribution”, explains why Europe is less unequal than the United States.

Wealth Inequality in South Africa, 1993-2017

Aroop Chatterjee, Léo Czajka, Amory Gethin

World Bank Economic Review, 36(1), 19-36, February 2022.

This article estimates the distribution of personal wealth in South Africa by combining microdata covering the universe of income tax returns, household surveys, and macroeconomic balance sheet statistics. South Africa is characterized by unparalleled levels of wealth concentration. The top 10 percent own 86 percent of aggregate wealth and the top 0.1 percent close to one-third. The top 0.01 percent of the distribution (3,500 individuals) concentrate 15 percent of household net worth, more than the bottom 90 percent as a whole. Such levels of inequality can be accounted for in all forms of assets at the top end, including housing, pension funds, and financial assets. There has been no sign of decreasing inequality since the end of apartheid.

Growing Cleavages in India? Evidence from the Changing Structure of Electorates, 1962-2014

Abhijit Banerjee, Amory Gethin, Thomas Piketty

Economic and Political Weekly, 54(11), 34-44, March 2019

This paper combines surveys, election results and social spending data to document a long-run evolution of political cleavages in India. The transition from a dominant-party system to a fragmented system characterized by several smaller regionalist parties and, more recently, the Bharatiya Janata Party, coincides with the rise of religious divisions and the persistence of strong caste-based cleavages. Education, income and occupation play a diminishing role (controlling for caste) in determining voters’ choices. There is no evidence of the new party system being associated with changes in social policy. This corroborates the fact that in India, as in many Western democracies, political conflicts are increasingly focused on identity and religious–ethnic conflicts rather than on tangible material benefits and class-based redistribution.

Can Redistribution Keep Up with Inequality? Evidence from South Africa, 1993-2019

Aroop Chatterjee, Léo Czajka, Amory Gethin

World Inequality Lab Working Paper 2021/20

Can government redistributive policies successfully curb rising inequality and foster inclusive growth in emerging economies? This paper sheds new light on this question by combining survey, tax, and historical administrative data to measure the incidence of taxes and transfers on the distribution of growth in South Africa since the end of the apartheid regime. Our new database is fully consistent with macroeconomic totals reported in the national accounts and allocates the entirety of government revenue and expenditure to individuals, including indirect taxes and in-kind transfers. We document a dramatic divergence in the growth of top and bottom income groups: between 1993 and 2019, the pretax income of the top 1% rose by 50%, while that of the poorest 50% fell by a third. However, the widening of pretax income gaps has been almost fully compensated by the growing size and progressivity of the tax-and-transfer system, effectively mirroring a “chase between rising inequality and enhanced redistribution”. The decline of racial inequalities since the end of apartheid has been entirely driven by the boom of top Black income groups, which is only marginally reduced by taxes and transfers. Our results have important implications for fiscal policy, the measurement of poverty, and the analysis of the link between inequality and growth.

How Large Are African Inequalities? Towards Distributional National Accounts in Africa, 1990-2017

Lucas Chancel, Denis Cogneau, Amory Gethin, Alix Myczkowski

World Inequality Lab Working Paper 2019/13

This paper makes a first attempt to estimate the evolution of income inequality in Africa from 1990 to 2017 by combining surveys, tax data and national accounts in a systematic manner. The low quality of the raw data calls for a lot of caution. Results suggest that income inequality in Africa is very high, and stands at par with Latin America or India in that respect. Southern and Central Africa are particularly unequal. The bulk of continent-wide income inequality comes from the within country component, and the between country component was even slightly reduced in the two last decades, due to higher growth in poorer countries. Inequality was rather stable over the period, with the exception of Southern Africa. Dualism between agriculture and other sectors and mining rents seem to be important determinants of inequality.
