A spectre has haunted the west: did socialism discipline income inequality?, por André Albuquerque Sant'Anna:
The aim of this paper is to discuss the role of the existence of a powerful socialist bloc as a disciplining device to inequality in western countries. The recent literature on top income inequality has emphasized explanations that go beyond the marginal productivity framework to explain top incomes. Usually the literature points to domestic factors such as top income tax rates and bargaining power. (...) In order to test our hypothesis, we run a panel of 18 OECD countries between 1960-2010. We find a robust and negative significant relation between Soviet Union’s relative military power and top income shares.
