Reasoning within the New Neoclassical Synthesis (NNS) we previously recommended that price stability should be the primary objective of monetary policy. We called this a neutral policy because it keeps output at its potential, defined as the outcome of an imperfectly competitive real business...

The central puzzle in international business cycles is that real exchange rates are volatile and persistent. The most popular story for real exchange rate fluctuations is that they are generated by monetary shocks interacting with sticky goods prices. We quantify this story and find that it can...

The Real Business Cycle (RBC) research program has grown spectacularly over the last decade, as its concepts and methods have diffused into mainstream macroeconomics. Yet, there is increasing skepticism that technology shocks are a major source of business fluctuations. This chapter exposits the...

This paper investigates the response of real wages and hours worked to an exogenous shock in fiscal policy. We identify this shock with the dynamic response of government purchases and tax rates to an exogenous increase in military purchases. The fiscal shocks that we isolate are characterized...

Both academic thinking about monetary economics and the practice of monetary policy have changed dramatically since 1971-1973, when the rational expectations revolution was beginning and the Bretton Woods system was crumbling. The present paper considers whether the various changes that have...

This paper constructs a simple model of home production that demonstrates the connection between the intertemporal elasticity of substitution in market consumption (IES) and the static elasticity of substitution between home and market consumption (SES), when the utility function is additively...

The real business cycle literature has largely ignored the empirical question of what role technology shocks actually play in business cycles. The observed procyclicality of total factor productivity (TFP) does not prove that technology shocks are important to business cycles, since demand...

I present an undetermined coefficients method for obtaining a linear approximating to the solution of a dynamic, rational expectations model. I also show how that solution can be used to compute the model's implications for impulse response functions and for second moments

Using data for the G7 countries, I estimate conditional correlations of employment and productivity, based on a decomposition of the two series into technology and non-technology components. The picture that emerges is hard to reconcile with the predictions of the standard Real Business Cycle...
