Exploiting the variation in wealth created by an Ethiopian housing lottery, we show that general attitudes towards redistribution and inequality aversion are not affected by a large and positive wealth shock. New homeowners are, however, less supportive of taxing homeowners, highlighting a potential conflict between self-interest and preferences for redistribution. We also find eviden ceof endogenous beliefs; relative to losers, the welthier winners are less likely to emphasize the role of luck in explaining economic success.We interpret this finding in terms of a self-serving bias.
