The Indeterminacy School in Macroeconomics exploits the fact that macroeconomic models often display multiple equilibria to understand real-world phenomena. There are two distinct phases in the evolution of its history. The first phase began as a research agenda at the University of Pennsylvania...

This paper presents a theory of the monetary transmission mechanism in a monetary version of Farmer's (2009) model in which there are 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...

This paper presents a model of the macroeconomy that reformulates what I take to be two important ideas from Keynes General Theory. The first is that there may be a continuum of steady state unemployment rates. The second is that beliefs select an equilibrium. I argue that search and matching...

This paper presents empirical evidence from U.S. data of a structurally stable aggregate supply relationship between real and nominal rates of interest and the rate of unemployment. The paper reviews theories of contracts that are based on the twin assumptions of asymmetric information and...

I review The End of Alchemy by Mervyn King, published by W.W. Norton and Company in 2016. I discuss King's proposed regulatory reform, the 'Pawn Broker for All Seasons' (PFAS) and I compare it to an alternative solution developed in my own work. I argue that unregulated trade in the financial...

This paper explains the connection between ideas developed in my recent books and papers and those of economists who self-identify as Post Keynesians. My own work is both neoclassical and 'old Keynesian'. Much of my published work assumes that people have rational expectations and that 'animal...

This paper constructs a general equilibrium model with two types of people where asset price fluctuations are caused by random shocks to the price level that reallocate consumption across generations. In this model, asset prices are volatile, and price-earnings ratios are persistent, even though...

This paper constructs a simple model in which asset price fluctuations are caused by sunspots. Most existing sunspot models use local linear approximations: instead, I construct global sunspot equilibria. My agents are expected utility maximizers with logarithmic utility functions, there are no...

Central banks throughout the world predict inflation with new-Keynesian models where, after a shock, the unemployment rate returns to its so called "natural rate'. That assumption is called the Natural Rate Hypothesis (NRH). This paper reviews a body of work, published over the last decade,...

This paper is about the effectiveness of qualitative easing; a government policy that is designed to mitigate risk through central bank purchases of privately held risky assets and their replacement by government debt, with a return that is guaranteed by the taxpayer. Policies of this kind have...
