Abstract

Why have decades of high and rising inequality in the United States not increased public support for redistribution? An established theory in political science holds that Americans’ distrust of government decreases their support for redistribution, but empirical support draws primarily on regression analyses of national surveys. I discuss the untestable assumptions required for identification with regression modeling and propose an alternative design that uses randomized experiments about political corruption to identify the effect of trust in government on support for redistribution under weaker assumptions. I apply this to three survey experiments and estimate the effects that large, experimentally induced increases in political trust have on support for redistribution. Contrary to theoretical predictions, estimated effects are substantively negligible, statistically indistinguishable from zero, and comparable to estimates from two placebo experiments. I discuss implications for theory building about causes of support for redistribution in an era of rising inequality and eroding confidence in government.

FIGURE 2.Trust in Government by Treatment Arm and Study TypeNote: Point estimates (with 95% CIs) are scaled by the standard deviation in control and denote average levels of trust in government for each experiment. Crossbars (with 95% CIs) denote group means pooled across experiments. See Table S.15 for point estimates and standard errors.

FIGURE 3.Estimates From OLS Regression with HC2 Robust Standard ErrorsNote: Thick horizontal lines denote 90% CIs and thin lines denote 95% CIs. Dotted vertical lines denote an MOE of ±0.20 standard units. Covariates: age, conservatism, income, indicators for partisanship (Republican, Democrat, Independent), sex (male or female), education (college degree or not), race (white or non-white), employed (yes or no), and a study fixed effect. See Table S.21 for point estimates and standard errors.

Gray horizontal lines indicate 95% CIs. Covariates: age, conservatism, income, indicators for partisanship (Republican, Democrat, Independent), sex (male or female), education (college degree or not), race (white or non-white), employed (yes or no), and a study fixed effect.
