models in the tradition of Tinbergen, Klein and others - namely the a

easing interdependencies between national economics in the wake of e.g

have also left their mark on the development as witnessed by the incre
asing concern for and importance of the rate of interest and the deter
mination of the exchange rate. These trends will be described and anal
ysed briefly in this article.
