Hysteresis is one of the main concepts used in Layard, Nickell and
Jackman′s book, Unemployment: Macroeconomic Performance and the
Labour Market. Attempts to clarify the concept of hysteresis, from
its formal representation to its empirical applications. Emphasizes the
idea that hysteresis refers back to a given set of formal properties,
independently of the phenomenologies within which it is liable to be
encountered. In economics, the fields concerned may indeed vary a lot
(labour market, foreign trade, etc.). By highlighting all the formal
properties of hysteresis, shows how the assimilation of phenomena
characterized by a zero eigenvalue for linear systems (or unit‐root
systems for discrete‐time processes) is wrong and, moreover, how the
imprecise use of the concepts can lead to the particular constraints
affecting unit‐root econometrics being overlooked.

The Reaction Functions of the German, French and English Monetary Authorities Virginie Coudert, Sanvi-Avouyi Dovi, Michel Boutillier, Richard Topol In the achievement of economic policy objectives, one of the key instruments of the national monetary authorities is the setting of the rate of interest in the money market. The behaviour of the authorities can be described by means of reaction functions, and estimates are provided in this article for the Federal Republic of Germany, France and the United Kingdom. The results indicate that the role accorded to monetary policy has been different in the various countries : in France priority is given to the external constraint ; in Germany to fighting inflation and minimising fluctuations in the mark-dollar rate ; and in the United Kingdom to protecting the value of the pound and controlling the money supply so as to control inflation.

For certain fundamental economic behaviour, comparing 1981 and 1982 economic evolutions with those of econometric equations tested on past comportments allows one to discern stability and discontinuity of behaviour. It also allows a better understanding of what is explained and what is unexpected in the observed situation : it further permits a better evalution of the impact of political decisions in the economic sphere.
Among the most noticable facts is that the drop in purchase of housing leads to a rise in consumption and not to a rise in investment. Firm level investment has remained at high levels with regard to the drop in profit and the stagnation in production. More directly than ever before, the rise in the domestic demand has given rise to a larger external deficit. The evolution of salaries has been relatively moderate, but in spite of that the slow-down of inflation has weighed upon firms.

The forecast results fall into three categories :
—those concerning the world economy : the evolutions expected in the USA, Germany, UK and Italy and also in world demand ;
—the short-term outlook for France as determined by the econometric model « OFCE-Annual » along with graphs illustrating the current analysis of business conditions ; —finally, the uncertainties concerning some elements of the forecast are considered viz the impact, in 1984, of a strong dollar (8 FF) and a lower increasing purchasing power of guaranteed minimum wage.

Cet article a été écrit par l'équipe MIMOSA, commune au CEPII et à l'OFCE. ; Mimosa, a macroeconomic model of the world economy, jointly built by the CEPII and the OFCE, is now operational. This article presents its main features and describes some monetary and fiscal multipliers. The economies of the six bigger industrialised countries are described in great detail by neo-keynesian models : a five product disaggregation distinguishes the energy sector, agriculture, the non-traded sector, the government sector and the industrial sector for which a putty-clay production function ensures compatibilities between employment, investment and production capacity behaviour. These models allow a precise analysis of the consequences of many kinds of monetary or fiscal policies. The rest of the world is divided into nine zones, more succinctly modelled : the model reveals in particular the financing constraints which bear on the imports of the less developed countries. International trade is analysed through a four product disaggregation. The article shows the model's properties while describing the impacts, in the country and abroad, of an increase in public expenditure in one of the major countries. It studies the consequences of a decline of the value of the dollar and finally the implications of a woldwide decrease in interest rates. Although it remains, in some respects, work in progress, the Mimosa model is already a useful tool for understanding the functioning of the world economy and for predicting its evolution. ; MIMOSA, modèle macroéconomique de l'économie mondiale, construit en commun par le CEPII et l'OFCE est maintenant opérationnel.
