A recently released research paper coming out of the IMF is worth your time. Particularly so if you find yourself making what you take to be a serious argument about the link between inequality and macroeconomic stability but can’t seem to get any respect. Over thirty years of neoliberalism it has been constantly argued that inequality was good for growth and economic stability; this IMF paper argues the opposite and has the neat feature that it is based in evidence rather than in elegant counter intuitive theory.
Below is the abstract for the research paper by Michael Kumhof and Romain Rancière (hat tip to Andrew Jackson over at PEF)
The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and eventual financial and real crisis.
The paper presents a theoretical model where these features arise endogenously as a result of a shift in bargaining powers over incomes. A financial crisis can reduce leverage if it is very large and not accompanied by a real contraction. But restoration of the lower income group’s bargaining power is more effective.
