This paper surveys briefly the main theoretical developments in the analysis of stock and flow integration in macro-economics, then proceeds to use this corpus of theory as a critique of the structure of existing macro-econometric models of the British economy. An outline is then suggested for a model which would take all of these stock-flow effects into account, given the macro-economic data currently available. In a following paper (Davis, 1987) we give a detailed account of estimation and simulation of such a stock-flow consistent model. *It should be emphasized that till recently this was partly also a consequence both of lack of data and of a relatively short economic policy horizon.
