Costly financial intermediation and excess consumption volatility

This paper documents the cyclical properties of financial intermediation costs and uses their dynamics to explain excess consumption volatility (ECV) differences across countries in a dynamic stochastic general equilibrium framework with housing market. I find that financial development levels have a limited role in explaining ECVs. Instead, the volatility of financial sectors plays the determinative role. Consistent with the data, the model finds higher ECVs in emerging countries. The paper also shows that if the US had the same intermediation cost structure as Turkey, deteriorations in the production and consumption following a financial shock would increase threefold.
