Are fairness perceptions shaped by income inequality? evidence from Latin America

A common assumption in the literature is that the actual level of income inequality shapes individuals’ beliefs about whether the income distribution is fair (“fairness views,” for short). However, individuals do not directly observe income inequality (which often leads to large misperceptions), nor do they consider all inequities to be unfair. In this paper, we empirically assess the link between objective measures of income inequality and fairness views in a context of high but decreasing income inequality. To do this, we combine opinion poll data with harmonized data from household surveys of 18 Latin American countries from 1997–2015. We find a strong and statistically significant relationship between income inequality and unfairness views across countries and over time. Unfairness views evolved in the same direction as income inequality for 17 out of the 18 countries in our sample. We find that individuals who are older, unemployed, and left-wing are, on average, more likely to perceive the income distribution as very unfair. Finally, we find that fairness views and income inequality have predictive power for individuals’ self-reported propensity to mobilize and protest independent of each other, suggesting that these two variables capture different channels through which changes in the income distribution can affect social unrest.
