Working Paper(14-004E) 「Heterogeneity and redistribution in financial crises」

This is working paper.

 This paper presents a simple heterogeneous agent economy model in order to show that the redistribution of wealth among heterogeneous agents can play a significant role in the propagation mechanism of financial crises. In an economy where firms with heterogeneous productivity operate under borrowing constraints, the redistribution of wealth reproduces hump-shaped responses for output and labor and procyclicality in observed productivity. In this model, a financial shock generates a persistent and hump-shaped response, whereas a productivity shock does not. It is also shown that the redistribution of wealth significantly amplifies the persistence and hump shape of output and labor in response to a financial shock. This model suggests that redistribution may thus be one of the key driving forces behind the transmission of financial crises.
