This paper discusses the consistent specification and estimation of asset demand equations in a disequilibrium model of financial markets. We estimate the effective asset demands of savings and loan associations, allowing for rationing in the mortgage market. These disequilibrium estimates are not very different from the estimates of notional demands with no rationing assumed. Savings and loans seem to be least affected by excess demand situations in that they are apparently not reluctant to raise mortgage rates and/or to ration borrowers.
