A general equilibrium model of an economy is presented where people hold money rather than bonds in order to economize on transaction costs. In any such model it is not optimal for individuals to instantaneously adjust their money holdings when new information arrives. The (endogenous) delayed...

In Part 1 the dynamics of an open market operation were analyzed for the case of logarithmic utility. Though such a utility function is useful for illustrative purposes, the implication that current prices are independent of current and future monetary injections is unsatisfactory. This...

The consumption based asset pricing model predicts that excess yields are determined in a fairly simple way by the market's degree of relative risk aversion and by the pattern of covariances between percapita consumption growth and asset returns. Estimation and testingis complicated by the fact...

What are the effects of open market operations? How do these differ from money falling from heaven? We propose a new explanation of how open market operations can change real and nominal interest rates which emphasizes three often mentioned but seldom explicitly articulated features of actual...
