The main purpose of this book is to review and discuss the different varieties of macro modelling. A second purpose is to analyze policy themes that are currently important in Finland and elsewhere. The last set of papers analyze exchange rate policies in Finland and issues in European Economic Integration. The reader will find both a useful overview of the different types of macroeconomic modelling of economic policies and some stimulating analyses of current issues in economic policy-making. The book is dedicated to Pertti Kukkonen on the occasion of his 60th birthday to honour his long and distinguished career as a participant and advisor in economic policy-making.
