Trend changes on raw materials markets

1987 saw a change in trends on many international raw materials markets. Prices, which had been under pressure for several years, began to rise again. This trend cannot be expected to continue everywhere in 1988, however.     

Raw materials price rise easing off

Due to the slow-down in the worldwide increase in business activity, the growth of demand for raw materials is expected to decelerate. Production, on the other hand, will continue to increase rapidly.     

Europeanizing the labour market: Employee mobility and company recruiting methods

With the completion of the single European market steps are to be made towards eliminating remaining impediments to the free movement of labour between Community countries such as an inadequate flow of information or the non-recognition of educational or training qualifications. How do companies respond to the extension of national labour markets by a European component?     

The structure of the IS discipline reconsidered: Implications and reflections from a community of practice perspective

The motivation of this paper is to advance the recent discussion about the identity of the Information Systems field with a social analysis of its community structures. It seeks to shed new light on the reasons why the field continues to debate its identity and to voice concerns about its recognition by other disciplines. For that purpose the paper adapts selected concepts from the community of practice literature for improving our understanding of the ways in which the IS research community differentiates itself into diverse constituencies, called communities of practice and knowing (CoP&K), and how these interact in the field’s complex processes of knowledge creation and dissemination. Our second purpose is to derive some tentative, actionable recommendations for the field from applying the concepts presented in the first part of the paper. The recommendations expand three fundamental ideas: (i) why a continuously updated history of the field could be an important contribution to support boundary spanning and identity formation; (ii) what the nature and role of fundamental criticism is for the IS research community and why it is necessary for the field’s future to pay more institutional attention to it; and (iii) how to improve understanding and communication within each paradigm constituency across a broad subset of different CoP&K through building a shared sense of collective historical accomplishments. The conclusions summarize the principal results which follow from our examination of the field’s community structures and insist that the CoP&K perspective concomitantly helps to better appreciate the underlying conditions from where the current IS disciplinary challenges have arisen; it also helps to suggest new priorities and possible strategies for dealing with these challenges.     

The integration of foreign employees in the labour market

For a number of European countries the presence of a more or less large number of foreign workers and their families is a fact to which they will have to adjust. As a rule, the longer the length of their stay, the less probable it becomes that these workers will return to their country of origin. In view of this fact it is necessary that the foreign workers and their families are integrated as comprehensively as possible, for humanitarian, social and economic reasons. The following article examines a number of indicators for integration so far in France, Germany (West), the Netherlands and Sweden.     

The nature of listed real estate companies: property or equity market?

This paper addresses the question of whether shares of public real estate companies should be treated as real estate or as equity investments. Because theoretical considerations do not suffice for making such a classification, we empirically investigate correlation structures and cointegration relationships of private and public real estate and equity markets for the United States and the United Kingdom. Our results suggest that public real estate stocks show similarities to the general stock market with regard to short-term return co-movements. For long-term investment horizons, the interdependence between direct and securitized real estate is much stronger. However, in the latter case, real estate stocks substantially lead the private property markets.

'Classical' Roots of Input-Output Analysis: A Short Account of its Long Prehistory

This paper discusses the roots of input-output analysis in 'classical' economics. The authors considered include Petty and Cantillon; Quesnay, the physiocrats and their critic Isnard; Smith, Ricardo, Torrens and Dmitriev; Marx, von Bortkiewicz and von Charasoff; Leontief; and Remak. It is argued that, in terms of method and content, input-output analysis is akin to the classical approach to the theory of production, distribution and relative prices in that (i) it requires all magnitudes to be observable and (ii) starts essentially from the same set of data. It is shown that many important modern concepts have been anticipated by the earlier authors. The prehistory of input-output analysis is also meant to provide new perspectives on potential future developments of the field.
