Purpose – The purpose of this study is to investigate the impacts of interval measured data, rather than traditional point data, on economic variability studies. Design/methodology/approach – The study uses interval measured data to forecast the variability of future stock market changes....

Purpose – The purpose of this paper is to associate a probabilistic confidence with the stock market interval forecasts obtained with the interval least squares (ILS) algorithm. The term probabilistic confidence in this paper means the probability of a point observation that will fall in the...

A structural break is viewed as a permanent change in the parameter vector of a model. Using taxonomies of all sources of forecast errors for both conditional mean and conditional variance processes, we consider the impacts of breaks and their relevance in forecasting models: (a) where the...

The introduction of new industrial legislation in 1987, in the former Soviet Union, followed a policy of decentralization in which factories were given increased authority to seek their own customers and suppliers, agree prices, and to engage directly in foreign trade. Additionally, from 1987,...

The process of consumer goods planning and demand research in a centralised socialist system, that of the German Democratic Republic (GDR) is presented and analysed. The system′s degree of centralisation and performance record; and its effectiveness in meeting consumer needs are evaluated and...

Examines influences of negativity on marketing management, e.g. the approach of scarcities of raw materials' emerging new consumer values; and a new international economic order — requiring co‐operation among rival organizations or governments. Pinpoints the petroleum crisis of December 1973...

Explores suitable ways of modifying cost‐plus pricing policies in the context of marketing based theory. Reports the findings of a research project concerned with the procedures followed in the pricing of consumer durables, and attempts to formulate an alternative statement of pricing...

Purpose – This paper seeks to present the key actors in Germany in the field of public forecasting and futures studies. Design/methodology/approach – Taking into account the highly decentralized nature of German institutions, and the reforms carried out since the reunification, it analyses...
