Toward efficiency in the crude-oil market

The ‘official’ (OPEC) prices of crude oil before the collapse in the oil market in the mid-1980s can be interpreted as contract prices and analysed on the basis of the theory of futures (or forward) markets. This paper uses the generalized method of moments estimation technique to test for efficiency in the relationship between the official prices and the ex-post spot prices at the time of delivery. Efficiency is rejected for the sample period 1978–1985 as a whole, but evidence is found of improvements over time. Further, the GMM Wald and Hansen tests, although asymptotically equivalent, are shown to differ greatly when applied to a small sample of monthly oil price data.     

Uncovering the supplier selection knowledge structure: A systematic citation network analysis from 1991 to 2017

Because of the critical role supplier selection plays in organizational success, both practitioners and academics have expressed a strong interest in the subject area generating an extensive body of research. The volume and breadth of publications in this area makes it difficult to understand the knowledge structure of the field and the academic work that has influenced the evolution of the domain.This mixed-method study systematically reviews 246 papers that investigated supplier selection issues and were published between 1991 and 2017. We initially examined the statistics of papers by unveiling influential journals, affiliations and articles. Second, we utilized co-citation network analysis, an objective procedure to extract clusters of what has been researched in supplier selection literature. The study analytically retrieves six major knowledge clusters: 1) conceptual foundation of the field; 2) modeling of the procurement environment; 3) handling group-decision making and unprecise input data; 4) computational research; 5) green/sustainable research and 6) risk-based supplier selection. Finally, we conducted main path analysis to get an overview of the evolution of knowledge in the supplier selection field by uncovering its major paths and key articles.     

Unemployment,inflation and price expectations with empirical results for Belgium

This article deals with the question whether there exists a trade-off between inflation and unemployment in the short as well as in the long run in the Belgian economy. A wage-price model incorporating the phenomenon of price expectations is presented. The model is verified empirically and an inquiry is made into the dynamic characteristics of Belgium's wage-price nexus. The main results of the paper are first that a positive answer may be given to the question we asked ourselves and secondly, that the possibility of explosive behaviour of wage and price changes is to be excluded.

Market as a Weapon: Domination by Virtue of a Constellation of Interests

The neoclassical approach toward explaining domination in the market is confronted with the approach of critical theory. Special attention is paid to domination by virtue of a constellation of interests in the market. This requires a particular technique for imposing will, namely conditional access to the market field. Interactions are modeled taking a field of domination composed of three organizational actors, one of them performing the function of drawing boundaries and controlling access. The concept of territoriality as spatially embedded power is applied to organization studies. Only one actor in the field has the ability to maximize its satisfaction, the two others minimize missed opportunities.

Rogues and Deviants: a game-theoretic perspective on opportunism in strategic alliances

ABSTRACT

This research examines how relational factors, such as monitoring, relative alliance identity (RAI), and trust, influence opportunism and, consequently, alliance performance. The authors suggest that the strategic alliances literature would benefit from recognising that opportunism does not always originate from the firm (rogue opportunism), but can also originate from individual employees (deviant opportunism). Hypotheses are tested in a multi-method approach within a business simulation and a cross-sectional sample of alliance executives. The results demonstrate a U-shaped relationship between trust and opportunism; however, monitoring moderates the relationship such that at high levels of trust, opportunism is practically non-existent. Further, results indicate that employees’ identification with the alliance impedes opportunism. Additionally, both types of opportunistic behaviours negatively impact the performance of partner firms and alliances.
