The New Keynesian sticky-price model has become increasingly popular for monetary-policy analysis. However, there have been conflicting results on the empirical performance of the model. In this paper, I attempt to reconcile these conflicting claims by examining various specifications of the model within the context of a single framework. I find that the New Keynesian model does not fit the U.S...

The marriage of micro-founded dynamic stochastic general equilibrium models and nominal rigidities has opened up new possibilities for policy analysis, and in particular for conducting welfare-based analysis using estimated macro models. Andy Levin, Alexsei Onatski, John Williams, and Noah Williams (henceforth LOWW) have exploited these possibilities in an excellent paper, one in which they acc...

In the 1970s, 1980s, and early 1990s, models used for monetary policy analysis combined the assumption of nominal rigidity with a simple structure that linked the quantity of money to aggregate spending. While the theoretical foundations of these models were weak, the approach proved remarkably useful in addressing a wide range of monetary policy topics.1 Today, the standard approach in monetar...

The Global Financial Crisis of 2007--2009 and its aftermath have called for a rethink the role money in shaping business cycle fluctuations. To this end, paper studies New Keynesian model with (liquidity). In model, agents hold government other financial assets. However, there is short rate disconnect (i.e., an interest spread) between policy on household's savings. shows that exists meaningful...

S ince John Maynard Keynes wrote the General Theory of Employment, Interest, and Money in 1936, Keynesian economics has been highly influential among academics and policymakers. Keynes has certainly had his detractors, though, with the most influential being Milton Friedman, Robert Lucas, and Edward C. Prescott. Monetarist thought, the desire for stronger theoretical foundations in macroeconomi...

This paper introduces heterogeneous expectations into a New Keynesian model. Our primary theoretical contribution is to provide an aggregation result for a model with nominal rigidities and heterogeneous bounded rationality. We incorporate bounded rationality at the individual agent level and determine restrictions on expectations operators sufficient to imply aggregate IS and AS relations of t...

Bennett McCallum (2009), applying Evans and Honkapohja’s (2001) results, argues that “learnability” can save New-Keynesian models from their indeterminacies. He claims the unique bounded equilibrium is learnable, and the explosive equilibria are not. However, he assumes that agents can directly observe the monetary policy shock. Reversing this assumption, I find the opposite result: the bounded...

As Paul Samuelson once put it: Adam Smith is dead and Keynes is dead; well— and Mises is dead, too. But Keynesianism is alive and well and back with a vengeance. Built on solid neoclassical foundations, this “new” Keynesianism, which features the effects of nominal rigidities in the presence of economic shocks and the existence of involuntary unemployment, represents the theoretical core of mod...

Standard micro-founded macroeconomics starts with optimization exercises to derive the precise behavior of the representative agent and regards the macroeconomy as a homothetic enlargement of a micro agent. This paper takes a different approach and presents a new micro-foundation for Keynesian economics. The key concept is stochastic macro-equilibrium, which is a natural extension of the labor ...
