S ince John Maynard Keynes wrote the General Theory of Employment, Interest, and Money in 1936, Keynesian economics has been highly influential among academics and policymakers. Keynes has certainly had his detractors, though, with the most influential being Milton Friedman, Robert Lucas, and Edward C. Prescott. Monetarist thought, the desire for stronger theoretical foundations in macroeconomi...

Standard micro-founded macroeconomics starts with optimization exercises to derive the precise behavior of the representative agent and regards the macroeconomy as a homothetic enlargement of a micro agent. This paper takes a different approach and presents a new micro-foundation for Keynesian economics. The key concept is stochastic macro-equilibrium, which is a natural extension of the labor ...

In the 1970s, 1980s, and early 1990s, models used for monetary policy analysis combined the assumption of nominal rigidity with a simple structure that linked the quantity of money to aggregate spending. While the theoretical foundations of these models were weak, the approach proved remarkably useful in addressing a wide range of monetary policy topics.1 Today, the standard approach in monetar...

We study identiÞcation in a class of three-equation monetary models. We argue that these models are typically not identiÞed. For any given exactly identiÞed model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to provide four examples of the consequences of lack of identiÞcation. In our Þrst two examples we show that it...

Perhaps the single most destructive tenet of Keynesian economics was its denigration of saving. Keynesianism has been used to justi~’ wasteful spending, massive deficits, and one after another scheme to redistribute wealth from those who would save it to those who would spend it. In keeping with this anti-saving doctrine, during the Christmas sellingseason of 1991, then President Bush made a bi...
