This paper is a follow on to our earlier papers exploring the dynamic properties of the UK continuous time macroeconometric model. This paper is focussed on policy implications. We take the position that the term "stabilization policy" implies that the economy would be unstable without policy,...

In this article, the predictability performance of certain classical business cycle theories are tested against contemporary statistical methods by using Finnish macroeconomic data. Keynesian multiplier- accelerator model derivatives and neo-classical real business cycle models are compared to...

The creation of electricity markets has raised the fundamental question as to whether markets provide the right incentives for the provision of the reserves needed to maintain system reliability, or whether some form of regulation is needed. In some states in the US, electricity retailers have...

Several recent papers conclude that U.S. real GDP is trend stationary, implying that all shocks are transitory and long run path is deterministic. These inferences fail to take into account two problems: the distortion of test size in finite samples due to data-based model selection, and the...

I employ a large set of scanner price data collected in retail stores and document that (i) although the average magnitude of price changes is large, a substantial number of price changes are small in absolute value; (ii) the distribution of non-zero price changes has fat tails; and (iii) stores...

In this paper, we study some of the properties of a discrete-time version of the two-class model of growth and distribution proposed by Pasinetti (1962) and Samuelson and Modigliani (1966) with a concave production function of the CES type. Two distinct groups of agents, workers and capitalists,...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult...
