This paper provides evidence for a low frequency relationship between unemployment, inflation and the nominal interest rate. I show that in the United States from 1959.1 to 1991.3, the unemployment rate, the inflation rate and the federal funds rate can be modelled as non stationary time series...

I show how to construct a stochastic long-lived overlapping generation’s model that is based on a non-stochastic model developed by Olivier Blanchard and Philippe Weil and that nests the RBC model as a special case. My innovation over previous work is to add an aggregate stochastic shock. I...

This paper develops a rational expectations model with multiple equilibrium unemployment rates where the price of capital may be unbounded above. I argue that this property is an important feature of any rational-agent explanation of a financial crisis, since for the expansion phase of the...

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 note shows that a big stock market crash, in the absence of central bank intervention, will be followed by a major recession one to four quarters later. I establish this fact by studying the forecasting ability of three models of the unemployment rate. I show that the connection between...

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 uses a model with a continuum of equilibrium unemployment rates to explore the effectiveness of fiscal policy. The existence of multiple steady states is explained by a model of costly search and recruiting that leads to a situation of bilateral monopoly. Using this framework, I...

Most dynamic stochastic general equilibrium models (DSGE) of the macroeconomy assume that labour is traded in a spot market. Two exceptions (Andolfatto [3], Merz [11]) combine the two-sided search model of Mortenson and Pissarides, [14], [13], [15] with a one-sector real business cycle model....
