Abstract

In this paper we analyze how growing income/wealth inequality and the functional income distribution inequality have contributed to the sustained low potential growth observed in the industrialized economies during the last two decades, a period that includes the Great Recession (GR). Growing inequality may constitute a drawback for the recovery of these economies, especially after the Great Pandemic (GP). To this aim, we modify the semi-structural model originally proposed by Holston, Laubach and William, by considering the effects of several types of inequalities. We jointly estimate potential growth and the natural interest rates. We show that the latter can substantially modify the time path of the real interest rate that prevails when economies are at full strength and inflation is stable.
