In the wake of the Great Recession, there has been substantial interest in the causes of inequality and the potential impacts of rising inequality on macroeconomic fluctuations. For the most part these examinations have approached the issue through the consideration of interpersonal income inequality.
This noted, there is a long tradition of Classical, Post-Keynesian and Kaleckian approaches that have long maintained the centrality of income distribution. These have focused primarily on the factor distribution of income –the share of income going to the various factors- as being key to understanding macroeconomic dynamics as well as inequality. Some work in this tradition additionally distinguishes the income going to ‘rentiers’ from that going to capitalists -breaking out, that is, returns to ownership of financial capital vs. physical capital. Given the ongoing discussions of widening inequality and the role of the financial sector in this propelled by the occupy movement this is an increasingly important issue.
