Four major behavioral characteristics are identified from summary data on U. S.postwar business cycles. These involve (1) the volatility of velocity growth in comparison with that of money growth, (2) the inertia of inflation, (3) the natural rate of unemploymentas a dividing line between Conditions of accelerating and decelerating inflation, and (4)the role of supply shocks.The volatility of nominal CNP growth suggests that a target for nominal GNP growth might be considered as a possible alternative to control of monetary aggregates. Major qualifications to the case for this approach include lags and forecasting errors, uncertainty about policy multipliers, uncertainty about the natural rate of unemployment,and recent critiques based on the rational expectations view of macro-economic behavior.The paper treats supply shocks and institutional rigidities as constraints faced by policymakers.These influence the optimal degree of monetary accommodation of supply shocks and the choice among a
