Political economy models predict that the rich oppose redistribution, and hence vote for conservative parties. Although this seems to fit the data well, I show that this is not true when we control for unobservable characteristics. Using Norwegian survey data, I study to what extent voting is caused by income. Unobserved characteristics correlated with income are handled by using fixed effects panel data discrete choice models. Although a positive association between income and conservative voting persists when controlling for unobservables, the magnitude of the effect is reduced by a factor of five. To correct for measurement error, I instrument income with average income by profession. The magnitude of the coefficients is increased, but the main conclusions remain.
