Abstract:
An economy in which deposit-taking banks of a Diamond and Dybvig style and a financial market coexist is modeled in a simple framework closely related to Diamond (1997). Solely depending on the fraction of naïve households who cannot efficiently invest directly in the cor-porate sector, two different types of financial systems emerge. With the fraction comparatively low, the evolving financial system can be interpreted as market-oriented, whereas a high frac-tion brings about a bank-dominated financial system. In market-oriented systems, banks only provide naïve households with access to efficient investments; in bank-dominated systems, banks' deposit contracts also offer some degree of liquidity insurance. Consequently, com-pared to market-oriented financial systems, the household sector in bank-dominated financial systems holds a larger portfolio fraction in deposits and a smaller part in direct investments. Analyzing the resilience of the different financial systems to various types of shocks shows that moderately bank-dominated (or hybrid) financial systems are particularly fragile, because only in these systems do fire sales of assets by distressed banks cause a deterioration in asset prices that also precipitates other banks into crisis.
