Testing for linearity in time series models has been an active area of research [see Granger and Terasvirta (1993), Tong (1991)]. The authors consider a test for linearity against a particular regime switching model known as the smooth transition autoregressive (STAR) model.

We prove a theorem on the existence of general equilibrium for a production economy with unordered preferences in a topological vector lattice commodity space. Our consumption sets need not have a lower bound and the set of feasible allocations need not be topologically bounded. Furthermore, we...

Recently, it has been shown that seasonal and business cycles are related and a similar economic mechanism is at work in producing both types of cycles. Thus, an analysis of seasonal fluctuations shed light on the nature of the business cycle. This paper uses the LM-type tests proposed by Canova...

This paper addresses some theoretical and econometric aspects of modelling addictive consumption. We show that the solution to the optimisation problem leads to a specification of the reduced form equation which is different from what is found in the literature. We also demonstrate that it is...

We consider economies with general consumption sets in a vector lattice commodity space. We show, by adapting the techniques of Mas-Colell and Richard (8) and Richard (10), the Edgeworth equilibria can be supported as pseudo-equilibria by continuous prices. A corollary of this result is that...

In an insightful, and delightfully short, paper that was published in the Journal of Political Economy in 1970, Siegfried provided an im- portant lesson about econometric methodology for all budding young econometricians. Unfortunately, there is a mistake in that paper. This short comment...
