In recent years there is evidence in the literature that various time series like GNP or production may be nonlinear. In this paper the question is examined whether there are non-linearities in the net production index for the producing sector of the FRG. Three different non-linearity tests are...

The non-stationarity of many macroeconomic time-series has lead to an increased demand for economic models that are able to generate fragile equilibria. For instance, the natural unemployment rate is al- lowed to shift over time depending on past unemployment. Actually, many European...

The purpose of this paper is to investigate whether shocks to out- put and employment had permanent or transitory effects during the period from 1961 to 1990 in the Federal Republic of Germany. There are a lot of parametric and non-parametric approaches which can be used for data generating...

Le sentier de croissance à taux constant 'endogène' peut être vu comme un nouveau fil du rasoir. Son existence repose sur la stricte égalité à un des rendements d'échelle vis-à-vis des facteurs accumulables. Nous étendons cette constatation en étudiant le sentier de croissance d'une...

This paper considers a special non-linear time series problem, that of testing for co-integration in a Bayesian framework when there is a break in the co-integrating relationship. It is shown that a partial linearization of the likelihood function solves many puzzling questions, in particular...
