Abstract
Are business cycles equally beneficial or harmful to consumers? Has welfare inequality increased or decreased due to rise of income/wealth inequality? By utilizing a heterogeneous agent RBC model with endogenous labor supply, this paper aims to answer these questions. We first show that while technology-driven business cycles are beneficial on average, a finding that is consistent with the recent literature, the welfare gain is not equally distributed; it is beneficial (resp. harmful) for agents who are relatively rich (resp. poor). The key to understanding the monotonic relationship between welfare gain from the business cycles and wealth level, a finding different from the previous literature that argues that there is a non-monotonic relationship between the two, is shown to be endogenous labor supply. Finally, we analyze the short run consequence of rising income/wealth inequality on welfare cost.
