Wage inequality has risen in many countries over recent decades. At the same time, production has become increasingly concentrated in a small number of firms. In this paper, we show that these two phenomena are linked. Theoretically, we show that shocks that increase concentration will also lead...

Our paper picks up the current controversial debate about increasing (income) inequality due to recent monetary policy measures in major advanced economies. We use a VAR framework identified with sign restrictions to figure out how income in- equality related measures react to monetary policy...

We develop a quantitative framework in which income inequality arises endogenously in response to productivity shocks. The framework accommodates sectoral inputoutput linkages, arbitrary elasticities of factors and intermediates, and heterogeneous workers that endogenously choose to supply their...

Franklin Delano Roosevelt said that “the test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.” According to the World Economic Forum (2021), income disparity is at the top of global risks in...

In contrast to previous research, I hypothesize that residential segregation patterns do not only result from an individual's perception of different ethnicities, but is rather affected by housing market interactions and socioeconomic endowment, like income and education. I implement a...

We conduct a Monte Carlo experiment using an ad-hoc New Keynesian model and a tractable agent-based model to generate artificial credit cycle episodes. We show that fluctuations in the implicit measures of the natural rate of interest obtained using a conventional trivariate Kalman filter on...

Wealth concentration in the U.S. has increased over the past 25 years across multiple methodologies for measuring wealth. But the reasons for the increase—and the timing of the increase—are quite different. In this note, we show that most available estimates are fairly consistent in level...

In this paper, we study the statistical properties of heterogeneous agent models with incomplete markets. Using a Bewley-Hugget-Aiyagari model we compute the equilibrium density function of wealth and show how it can be used for likelihood inference. We investigate the identifiability of the...
