The chapters of this book provide a better understanding of wine economics, by addressing new issues such as sustainable development, food authenticity, financial expectations and consumption economics. Many of the discussed topics have been recently developed by economists (e.g. global warming and wine tourism) despite having been mostly covered by specialists in management, marketing and geography. Other fields correspond to new investigations of traditional topics, such as ranking wines or consumer behaviour, and new analyses in strategic choice (for example how to bottle wine or to sell bulk wine, to select grape varieties at replanting, to distinguish attitudes, intentions and behaviour in exporting). "Wine Economics" draws attention to the positioning of different market players and explores alternative regulations for public policy.

o. Guvenen, University of Paris IX-Dauphine The aim of this publication is to present recent developments in international com modity market model building and policy analysis. This book is based mainly on the research presented at the XlIth International Conference organised by the Applied Econometric Association (AEA) which was held at the University of Zaragoza in Spain. This conference would not have been possible with out the cooperation of the Department of Econometrics of the University of Zaragoza and its Chairman A.A. Grasa. I would like to express my thanks to all contributors. I am grateful to J.H.P. Paelinck, J.P. Ancot, A.J. Hughes Hallett and H. Serbat for their constructive contributions and comments concerning the structure of the book. vii INTRODUCTION o. Guvenen The challenge of increasing complexity and global interdependence at the world level necessitates new modelling approaches and policy analysis at the macroeconomic level, and for commodities. The evaluation of economic modelling.follows the evolution of international economic phenomena. In that interdependent context there is a growing need for forecasting and simulation tools in the analysis of international primary com modity markets."

The book proposes an overview of the research conducted to date in the field of wine economics. All of these contributions have in common the use of econometric techniques and mathematical formalization to describe the new challenges of this economic sector.

RONALD C. DUNCAN During the 1980s, substantial advances were made in the global modelling of commodity markets in several areas, advances which were reflected in many of the papers delivered to the Applied Econometrics Association meeting held at the World Bank in Washington, DC, in October 1988. The several areas where I see advances being made, some of which the International Commodity Markets Division of the World Bank has taken part in, are the following: (a) in the theoretical specification of commodity price behaviour; (b) in the increased emphasis on modelling imperfect markets; (c) in the incorporation of the interrelationships between macro economic and commodity market variables; (d) in the specification of supply response, particularly in respect of perennial crops; and (e) in the realization of complementarity between time series analysis and economet rically estimated structural models. Improvements in the specification of the commodity price formation process have probably been the most important of the above advances. Until the early 1980s, prices were modelled as a simple linear function of stocks. Gilbert has played an important role in introducing the rational expecta tions hypothesis into the specification of commodity prices. Recent work by Gilbert, Trivedi, and Deaton and Laroque offers the possibility of non-linear specification of the relationship between prices and stocks within an expectational framework and of thereby capturing the phenomenon of sharp run-ups in commodity prices. Gilbert has also played an important role in clarifying the interrelation ships between macroeconomic variables and primary commodity prices."

This book is based on an international conference organised by the Applied Econo- metric Association (AEA) on International Macroeconomic Modelling which was held in Brussels at the Commission of the European Communities in December 1983. On behalf of the Applied Econometric Association, we would like to extend our thanks to all participants and contributors. This conference would not have been possible without the cooperation and support of the Commission of the European Economic Communities and of its Directorate General for Economics and Financial Affairs (DGII) staff, in particular M. Emerson, A. Dramais, and also H. Serbat of the Paris Chamber of Commerce and Industry. Our thanks go also to J.P. Ancot for his constructive comments concerning the structure of this book. We are grateful to M. Russo, R. Maldague and Y. Ullmo for opening the con- ference with their stimulating review and comments on the use of international macroeconomic models; and to R. Bird, A.M. Costa, A. Crockett, H. Guitton, J.C. Milleron, J. Paelinck, J. Waelbroeck for chairing the scientific sessions. P. Artus F. Gagey O. Guvenen vi INTRODUCTION The main focus of this book is to present recent developments in the construction and use of international macroeconometric models. Four main aspects are selected: (i) analysis of trade linkages and exchange rate determination; (ii) modelling and simulating the international economy; (iii) international policy coordination; (iv) the use of international macroeconomic models.
