The first 150 words of the full text of this article appear below. The year 1982 was not a particularly good period for the worldeconomy. At year's end, the Organization for Economic Cooperationand Development (OECD) revised its growth figures for membernations from slightly over 1% to –0.5%, with some 32 millionunemployed in its 24 member states. In the United States thejobless rate was 11% and 30% of plant capacity stood idle. OttoEckstein found the economy in its worst shape in nearly halfa century. Truly the year belonged to Scrooge. Yet 1982 was a very good year indeed for financial econometrics,the debut of an explosion of activity in the area that continuesvigorously 20 years later, as the emergence of the Journal ofFinancial Econometrics attests. In fact, it can convincinglybe argued that 1982 heralded the beginning of our subject, andperhaps with the recent awarding of the Nobel Prize in Economicsto Robert Engle . . .

We extend the research on postinjury employment by estimating productivity losses for workers with permanent partial disabilities (PPDs) in the first three years after injury. Our method distinguishes between productivity losses attributed to spells of work absence versus reduced earnings during spells of employment. The method is applied to data for 800 Ontario workers with PPDs. The results document large productivity losses persisting at least three years after injury, with different loss patterns for workers returning to stable versus unstable employment. Human capital investments or job accommodations can reduce productivity losses, but the significant determinants of losses differ for the stable versus unstable employment groups.  相似文献

This paper uses a real option approach to analyze the impact of alternative marketing contracts on the decision to invest in a cooperatively owned hog facility. For the numerical analysis of the impact, this paper uses a simulation method that incorporates early exercise, multiple‐state variables, multi‐choice decisions and temporal optimality. The results show that the option values that stem from the value of waiting to invest and choosing between alternative marketing methods amounts to 20–36% of the initial investment. Further, having an option to choose an alternative marketing method with different risk structure does add to the value of waiting to invest. Having an option to enter a 15‐year marketing contract increases the value of waiting by as much as $117,097 for the pork production example in this paper. Finally, the value of the option to wait is unilaterally lower under a risk‐reducing contract scenario than under a spot market alternative. This could explain the explosion in hog production facility investment during the 1990s when prevalence of contract production increased. Les auteurs ont recouru à l'approche du choix véritable pour analyser l'impact d'autres solutions de mise en marché sur la capacité d'investir ou pas dans un élevage de porcs exploitéà la manière d'une coopérative. Aux fins de l'analyse, on s'est servi d'une méthode de simulation intégrant une brève campagne, de multiples variables d'État, des décisions à choix multiple et des conditions optimales dans le temps. Les résultats indiquent que l'existence d'un choix réel permettant à l'exploitant d'attendre avant d'investir et de sélectionner entre plusieurs méthodes de mise en marché représente 20 à 36 pour cent de l'investissement initial. Par ailleurs, le fait d'avoir accès à une autre méthode de mise en marché, à structure de risque différente, ne donne pas plus de valeur à la capacité d'attendre avant de procéder aux investissements. La possibilité de signer une entente de commercialisation de quinze ans accroît la valeur de l'attente de jusqu'à 117,097 $ pour le type d'élevage porcin retenu comme exemple. Enfin, l'existence d'une entente de commercialisation atténuant les risques réduit unilatéralement la valeur de l'option « attente », comparativement à ce qui se produit quand l'éleveur n'a d'autre choix qu'écouler ses bêtes sur le marché au comptant. Ces résultats pourraient expliquer l'explosion des investissements observée dans le secteur du porc au cours des années 90, où la production sous contrat avait sensiblement augmenté.  相似文献

STRATEGIC INVESTMENT DECISION-MAKING: COMPLEXITIES, POLITICS AND PROCESSES*   总被引:1,自引:0,他引:1  
This article is a preliminary report on an investigation into the processes of investment decision-making. Three case studies from three firms are presented which show disparities in a number of aspects of process, for example, the length of time taken to arrive at a decision, the number and intensity of disagreements and uncertainties encountered. Data were collected for these cases through semi-structured interviewing from multiple informants in the three organizations, thereby permitting the use of analysis of variance techniques of the different perspectives given by informants. Perceptions of the effectiveness of the decisions were also gathered. One finding from the study is that the decisions with the lowest perceived effectiveness (in firm HE) also lost support from those involved in making the decision during the process, although the decision was eventually implemented. This decision also had the least agreement amongst informants as to the main sources of disagreements. Informants of all three decisions saw effect upon product quality and productivity, fit with business strategy and competitive position of the company as the most important factors to take into account in evaluating the decisions. In firm CG, however, there were disagreements as to how the investment should be evaluated. In the conclusions to the article a disucssion is given as to the nature of evaluation procedures in relation to the developing theory of information systems.  相似文献

Business-to-business marketing research has a long tradition of using qualitative case studies. Industrial Marketing Management (IMM) has actively encouraged the use of case methods, resulting in many important theoretical advances in the field. However, debate still rages over what constitutes “good case research”. This article addresses this issue from a positivist standpoint. We examine the how authors address issues of quality in the 105 qualitative case studies published in IMM between 1971 and 2006. Four periods were identified: 1971-1979, 1980-1989, 1990-1999, and 2000-2006. Findings demonstrate that, from a positivist viewpoint, there has been a steady improvement in how authors addressed issues of research quality in published qualitative case studies. Suggestions for changes in data presentation, reviewer expectations, the IMM reviewer feedback form, and the use of web-based appendices containing data pertinent to reader judgments of research quality are suggested.  相似文献

This paper focuses much‐needed attention on the ethical nature of customer relationship management (CRM) strategies in organisations. The research uses an in‐depth case study to reflect on the design, implementation and use of ‘best practice’ associated with CRM. We argue that conventional CRM philosophy is based on a fairly narrow construct that fails to consider ethical issues appropriately. We highlight why ethical considerations are important when organisations use CRM and how a more holistic approach incorporating some of Alasdair MacIntyre's ideas on virtue ethics could be relevant.  相似文献
