The rational expectations framework demonstrates that aggregate output does not increase as a result of anticipated expansionary policy and that the economy immediately moves to a point of long-run equilibrium (point 2) where aggregate output is at the natural rate level. Most mainstream macroeconomic theoretical innovations since the 1970s (the New Classical rational expectations revolution associated with such names as Robert E. Lucas Jr., Edward Prescott, Thomas Sargent, Robert Barro etc, and the New Keynesian theorizing of Michael Woodford and many others) have turned out to be self-referential, inward-looking distractions at best. Indeed, by way of an example, we show that if expectations are a weighted average of rational and adaptive expectations, then even a small degree of heterogeneity can render a determinate model indeterminate. We have already had forward-looking households and firm making savings and investment decisions as well as central bank forecasting and decision-making.
