Abstract

Real business cycles are recurrent fluctuations in an economy's incomes, products, and factor inputs – especially labour – that are due to non-monetary sources. These sources include changes in technology, tax rates and government spending, tastes, government regulation, terms of trade and energy prices. Most real business cycle (RBC) models are variants or extensions of a neoclassical growth model. One such prototype is introduced. It is then shown how RBC theorists, applying the methodology of Kydland and Prescott (Econometrica 1982), use theory to make predictions about actual time series. Extensions of the prototype model, current issues and open questions are also discussed.
