This paper begins with the observation that the volatility of factor input growth is insufficient to explain the volatility in the growth rate of output, and explores the empirical plausibility of the hypothesis that this fact is due to the presence of productive externalities and increasing...

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 nature of price dynamics has long been thought important for the origin and duration of business cycles. To investigate this topic, we construct a dynamic stochastic general equilibrium macroeconomic model in which monopolistically competitive firms face fixed costs of changing the nominal...

Development of rational expectations models of the business cycle has been the central issue in macroeconomics over the last 15 years. The postulate that expectations are rational imposes considerable discipline on business cycle analysis. In this essay we review the current literature on...

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...
