Democracies pay higher wages

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.
