Disequilibrium macroeconomics, money as a buffer stock and the estimation of money demand

Standard explanations of the seeming instability of the money demand in the post-1973 period usually link to stories about financial innovation and deregulation. I propose an alternative hypothesis: Much of the seeming instability occurs because of shifts in monetary policy, either explicit or implicit, in an environment where the Federal Reserve controls a more “exogenous” money stock. My econometric analysis modifies existing methods for estimating markets in disequilibrium and incorporates newly developed cointegration and error-correction modeling. My findings provide support for the buffer-stock interpretation of the money market.
