This paper presents a two-sector growth model which allows indeterminacy to occur at relatively mild degrees of increasing returns. It is shown that economies of scale need only be present in one sector of the economy, e.g. the investment good producing sector. This new feature of the model builds o

โฆ Synopsis
This paper uses maximum likelihood to estimate a prototypical real business cycle model under several di!erent assumptions regarding the stochastic process governing technological change. The estimation approach permits the use of formal statistical hypothesis tests to help discriminate between competing speci"cations; the approach also allows each speci"cation to be evaluated based on its ability to generate accurate out-of-sample forecasts. Overall, the results indicate that the data prefer a version of the model in which technology shocks are extremely persistent but still trend stationary.

In this paper the business cycle properties of UK data are investigated using a VAR technique. A Real Business Cycle (RBC) model is formulated. The model includes both permanent and transitory shocks to technology. The business cycle properties of the data and the model are investigated by deriving
## Abstract This paper explores the effects of the US business cycle on US stock market returns through an analysis of the equity risk premium. We propose a new methodology based on the SDF approach to asset pricing that allows us to uncover the different effects of aggregate demand and supply shoc
The goal of this paper is to examine the relative importance of permanent and transitory shocks in explaining variations in macroeconomic aggregates for the UK at business cycle horizons. Using the common trend-common cycle restrictions, we estimate a variance decomposition of shocks, and find that
