Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market incompleteness or transactions costs of any kind. Instead, we modify a...

This paper describes research that integrates Keynesian and Walrasian economics in a new way. The author develops a model in which high unemployment can persist and any unemployment rate can occur as an equilibrium. Equilibrium is selected by the self-fulfilling beliefs of asset market...

We develop a set of necessary and sufficient conditions for equilibria to be determinate in a class of forward-looking Markov-switching rational expectations models, and we develop an algorithm to check these conditions in practice. We use three examples, based on the new Keynesian model of...

Davig and Leeper (2007) have proposed a condition they call the generalized Taylor principle to rule out indeterminate equilibria in a version of the New Keynesian model, where the parameters of the policy rule follow a Markov-switching process. We show that although their condition rules out a...

We develop a new method for computing minimal state variable solutions (MSV) to Markov-switching rational expectations models. We provide an algorithm to compute an MSV solution and show how to test a given solution for uniqueness and boundedness. We construct an example that is calibrated to...

"In the aftermath of the 2008 financial crisis, economists around the world have advanced theories to explain the persistence of high unemployment and low growth rates. According to Roger E. A. Farmer, these theories can be divided into two leading schools of thought: the ideas of pre-Keynesian...
