A dynamic linear demand schedule for labor is estimated and tested. The hypothesis of rational expectations and assumptions about the orders of the Markov processes governing technology impose over-identifying restrictions on a vector autoregression for straight-time employment, overtime employment, and the real wage. The model is estimated by the full information maximum likelihood method. The model is used as a vehicle for re-examining some of the paradoxical cyclical behavior of real wages described in the famous Dunlop-Tarshis-Keynes exchange.

In this paper, we examine various exchange rate regimes, paying particular attention to what difference the monetary-fiscal policy choices of governments make. The exchange rate may be market-determined or fixed, and if fixed, either cooperatively or by one government alone. Further, capital controls may or may not apply. Our most important result, quite general, we believe, is that absent capital controls the equilibrium exchange rate of the floating rate regime is indeterminate. It makes no sense to advocate floating rates and unfettered international borrowing and lending.

This paper puts forward a method of policy simulation with an existing macroeconometric model under the maintained assumption that individuals form their expectations rationally. This new simulation technique grows out of Lucas’ criticism that standard econometric policy evaluation permits policy rules to change but doesn’t allow expectations mechanisms to respond as economic theory predicts they will. The technique is applied to versions of the St. Louis Federal Reserve model and the Federal Reserve-MIT-Penn (FMP) model to simulate the effects of different constant money growth policies. The results of these simulations indicate that the problem identified by Lucas may be of great quantitative importance in the econometric analysis of policy alternatives.

It is commonly asserted that with excess plant capacity, expansive policy stimulates output and lowers unemployment without substantially boosting inflation, while at full capacity most of the impact is on inflation. This assertion is critically examined. First, two common definitions of capacity--engineering and economic—are examined and found to be nebulous. The concepts of supply and demand are older, but better. Full capacity is reinterpreted as points where the supply curve is steep and excess capacity as points where it is fairly flat. Then the "Keynesian" model in which stimulative policy shifts only the demand curve is compared to the "classical" model where stimulative policy shifts both demand and supply curves. For the former model the assertion on capacity utilization is correct, while in the latter it is not. Empirical tests are performed to determine whether measured capacity utilization is useful for predicting inflation. The tests are ambiguous, but certainly do not strongly favor capacity utilization.

This paper presents a monetarist model of the business cycle with price-setting firms. The model is estimated, and the point estimates used in simulations to illustrate the properties of the model. The real goods market is found to be stable, although subject to sharp changes in output. This model is consistent with rational expectations. Nevertheless, monetary policy can have a lasting impact, and the simulations show this to be the case. Fiscal policy too is found to influence the business cycle, but its short-run effects are substantially smaller than its impact effects. The possibility of an activist government policy in this model does not imply the efficiency of an activist policy.
