• Abstract

  In this paper, we investigate the effect of bank capital adequacy on the economic boom-bust cycles. To investigate this effect, we use a Dynamic Stochastic General Equilibrium (DSGE) model with a news shock. We perform the simulation three type of shocks: a monetary shock, capital price shock with no news shock, and capital price shock with news shock. In terms of the effect of bank capital adequacy, in both the simulation of simple capital price shock, we investigate the countercyclicality of the Basel III type. In particular, for the economic boom-bust cycle, the Basel III framework implies that it mitigates the increase in output in periods of boom and the decrease in output in period of bust depending on the elasticity of output growth.
