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...

DSGE models are characterized by the presence of expectations as explanatory variables. To use these models for policy evaluation, the econometrician must estimate the parameters of expectation terms. Standard estimation methods have several drawbacks, including possible lack or weakness of...

"Of all the economic bubbles that have been pricked," the editors of The Economist recently observed, "few have burst more spectacularly than the reputation of economics itself." Indeed, the financial crisis that crested in 2008 destroyed the credibility of the economic thinking that had guided...

The representative agent model (RA) has dominated macroeconomics for the last thirty years. This model does a reasonably good job of explaining the co-movements of consumption, investment, GDP and employment during normal times. But it cannot easily explain movements in asset prices. Two facts...

This paper studies the connection between the stock market and the unemployment rate. I establish three facts. First, the log of the real value of the S&P 500 and the log of a logistic transformation of the unemployment rate are non-stationary cointegrated series. Second, the stock market...

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 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...
