In this paper we aim at testing the inflation persistence hypothesis as well as modelling (using logistic smooth transition autoregressive, LSTAR, models) the long run behaviour of inflation rates in a pool of African countries. In order to do so, we rely on unit root tests applied to nonlinear...

This paper tests the view that the relation between unemployment and entrepreneurship is dynamic and possibly nonlinear. It performs Granger-causality tests and STAR-EXT estimation to assess the causality direction and the nonlinear nature of the relation for a set of OECD countries. The results...

In this paper, we aim to provide further insights into the importance of real oil price as a determinant of real exchange rates for a pool of African countries. While this relationship has been explored substantially for many industrialised economies, African countries have received little...
