Controlling for labor productivity, income levels, and other possible determinants, there is a robust and statistically significant association between the extent of democracy and the level of manufacturing wages in a country. The association exists both across countries and over time within countries. The coefficient estimates suggest that nonnegligible wage improvements result from the enhancement of democratic institutions: average wages in a country like Mexico would be expected to increase by 10 to 40 percent if Mexico were to attain a level of democracy comparable to that prevailing in the United States. Political competition and participation seem to be the driving force behind the result.

We study the relationship between politics and economic growth in a simple model of endogenous growth with distributive conflict among agents endowed with varying capital/labor shares. We establish several results regarding the factor ownership of the median individual and the level of taxation, redistribution, and growth. Policies that maximize growth are optimal only for a government that cares solely about pure “capitalists.” The greater the inequality of wealth and income, the higher the rate of taxation, and the lower growth. We present empirical results that show that inequality in land and income ownership is negatively correlated with subsequent economic growth.
