Transactions Costs, Inflation, and the Variety of Intermediation Services
构建了一个包含金融中介固定成本和交易成本的一般均衡模型,发现忽略固定成本在托宾-鲍莫尔型货币需求模型中并非无害,且通货紧缩可能是最优的,而准备金要求变化的影响不确定。
A general-equilibrium model with fixed costs of financial intermediation and costs of transacting with intermediaries is constructed. This model is used to show that ignoring fixed costs of in termediation is not innocuous in Tobin-Baumol-type transactions cost models of money demand. Deflation is optimal in spite of the fact that an increase in inflation reduces nominal interest rates and may increase the transactions costs incurred by all groups of economic agents. Changes in reserve requirements have ambiguous effects. The authors obtain novel results due to the fact that the variety of intermediation services is affected by government intervention.
