内容简介：We document a new channel mediating the effects of monetary policy and regulation, the disintermediation channel. When the interest rate on excess reserves (IOER) increases, fewer banks are intermediating in the Fed funds market, and they intermediate less. Thus, the total Fed funds traded decreases. Similarly, disintermediation happens after the balance sheet cost rises, e.g. the introduction of Basel III regulations. The disintermediation channel is significant and supported by empirical evidence on U.S. banks. To explain this channel, we develop a continuous-time search-and-bargaining model of divisible funds and endogenous search intensity that includes the matching model (e.g. Afonso and Lagos, 2015) and the transaction cost model (e.g. Hamilton, 1996) as special cases. We solve the equilibrium in closed form, derive the dynamic distributions of trades and Fed funds rates, and the comparative statics of aggregate moments of the Fed funds market. IOER reduces the spread of marginal value of holding reserves, and hence the gain of intermediation. In general, the equilibrium is constrained inefficient, as banks trade too frequently.
