This paper presents a theory of the monetary transmission mechanism in an old-Keynesian model with multiple equilibrium unemployment rates. The model has two equations in common with the new-Keynesian model; the optimizing IS curve and the policy rule. It differs from the new-Keynesian model by...

This paper studies a New Keynesian model in which monetary policy may switch between regimes. We derive sufficient conditions for indeterminacy that are easy to implement and we show that the necessary and sufficient condition for determinacy, provided by Davig and Leeper, is necessary but not...

We extend Farmer's (2012b) Monetary (FM) Model in three ways. First, we derive an analog of the Taylor Principle and we show that it fails in U.S. data. Second, we use the fact that the model displays dynamic indeterminacy to explain the real effects of nominal shocks. Third, we use the fact the...

This paper uses the old-Keynesian representative agent model developed in Farmer (2010b) to answer two questions: 1) do increased government purchases crowd out private consumption? 2) do increased government purchases reduce unemployment? Farmer compared permanent tax financed expenditure paths...
