Industrial marketing research has failed to receive its due attention in marketing books and journals, even though the volume of transactions in industrial goods and services is more than twice that of consumer goods and services. This article provides a systematic and wide ranging review of the issues, procedures, and opportunities found in industrial marketing research. 相似文献

ABSTRACT: Business schools are facing a rapidly changing environment as new technology and alternative delivery systems erode barriers of time and place. The authors analyze the practices for determining curricula and courses offered by a major state university's business school and conclude that the school operates as a command economy. Such a structure produces artificial demand for some courses and obfuscates the measurement of true student preferences. The authors propose that, at least for full-capacity courses, enrollment should be replaced as a demand measure by one based on attempts to enroll. The authors' demand measure provides significantly different results from the traditional enrollment measure. The authors' results also provide insight into the relative preferences of students for different courses at the business school and the factors affecting these preferences, with some positive implications for the risk management and insurance discipline. 相似文献

Abstract In this paper we consider the Sparre Andersen insurance risk model. Three cases are discussed: the ordinary renewal risk process, stationary renewal risk process, and s-delayed renewal risk process. In the first part of the paper we study the joint distribution of surplus immediately before and at ruin under the renewal insurance risk model. By constructing an exponential martingale, we obtain Lundberg-type upper bounds for the joint distribution. Consequently we obtain bounds for the distribution of the deficit at ruin and ruin probability. In the second part of the paper, we consider the special case of phase-type claims and rederive the closed-form expression for the distribution of the severity of ruin, obtained by Drekic et al. (2003, 2004). Finally, we present some numerical results to illustrate the tightness of the bounds obtained in this paper. 相似文献

This paper estimates a multivariate Tobit system of monthly wholesale dairy prices where four prices are lower censored by the dairy price support programme. Using Maximum Simulated Likelihood (MSL) the effects of simulation noise are tested/corrected for and the relevance of estimating multivariate versus the single Tobit equations discussed. 相似文献

An Empirical Examination of Institutional Investor Preferences for Corporate Social Performance 总被引:2,自引:0,他引:2
This study investigates the pattern of institutional shareholding in the U.K. and its relationship with socially responsible
behavior by companies within a sample of over 500 UK companies. We estimate a set of ownership models that distinguish between
long- and short-term investors and their largest components and which incorporate both aggregated and disaggregated measures
of corporate social performance (CSP). The results suggest that long-term institutional investment is positively related to
CSP providing further support for earlier studies by Johnson and Greening (1999, Academy of Management Journal 42, 564–576) and Graves and Waddock (1994, Academy of Management Journal 37, 1034–1046). Disaggregation of CSP into its constituent components suggests that the pattern of institutional investment
is also related to the form which CSP takes. Investigation of the impact of investment screens on the selection of stocks
suggests that long-term institutional investors select primarily through exclusion, rejecting those firms which have the worst
CSP. 相似文献

This study estimates the impact on commercial banks' interest-rate behavior of the more pervasive regulatory measures adopted
by the Central Bank of Barbados. The results indicate that the cash ratio, the stipulated government securities ratio, and
the savings deposit rate floor significantly impacted the loan rate for every bank. Generally, the deposit rate for any given
bank has been responsive to fewer policy variables than the loan rate. The loan rates, though generally responsive to all
policy variables other than the bank rate, have exhibited very low elasticities. The results indicated that the ceiling on
the average lending rate, when it existed, depressed loan rates by less than 1 percent on average. This is largely attributable
to the Central Bank's policy of adjusting the ceiling in line with market trends. 相似文献

Abstract This article examines the pricing of catastrophe risk bonds. Catastrophe risk cannot be hedged by traditional securities. Therefore, the pricing of catastrophe risk bonds requires an incomplete markets setting, and this creates special difficulties in the pricing methodology. The authors briefly discuss the theory of equilibrium pricing and its relationship to the standard arbitrage-free valuation framework. Equilibrium pricing theory is used to develop a pricing method based on a model of the term structure of interest rates and a probability structure for the catastrophe risk. This pricing methodology can be used to assess the default spread on catastrophe risk bonds relative to traditional defaultable securities. 相似文献

Abstract . Identifying who are the urban poor may help determine why poverty exists in our cities; and, of course, knowing why people are poor is a prerequisite for designing effective policies to eradicate the problem. As the statistics presented in this paper demonstrate, poverty has many causes and, therefore, a successful ‘war’ on poverty will necessarily have to be long term and multi-programmed. One essential part of that ‘war,’ of course, will be an attack on racial and sexual discrimination in labor markets; but, as this paper's analysis of the possible underlying causes of such discrimination points out, economic progress alone may be insufficient—racial and sexual prejudice itself will have to be eradicated. 相似文献

An Economic Analysis of the Effects on the World Dairy Sector of Extending Uruguay Round Agreement to 2005 总被引:1,自引:0,他引:1

A spatial equilibrium model of the world dairy sector is used to simulate the regional impacts of extending the 1995 Uruguay Round Agreement on Agriculture (URAA) dairy commitments to 2005. In particular, the import quota, within- and over-quota import tariff and export subsidy components of the URAA dairy commitments are analyzed both separately and jointly. This analysis provides insight into the tradeoffs among the various components of the URAA dairy trade liberalization. Extending the URAA to 2005 more than doubles the producer and consumer welfare impacts of the GATT 2000 relative to the BASE scenario for most regions. Aggregate producer and consumer welfare changes are estimated to be in the $2–5 billion range. Results suggest that western Europe remains heavily protected even after the URAA extension to 2005, and its dairy producers will lose the most with further, post-URAA dairy trade liberalization. In contrast, dairy producers in low-cost exporting regions (New Zealand, Australia and South America/South) will gain the most. Impacts of GATT 2005 on Japan, the U.S. and Canada are found to be relatively small. Un modèle àéquilibre spatial du secteur laitier mondial est utilisé pour simuler les impacts régionaux d'une reconduction des engagements laitiers de l'Accord sur l'agriculture de l'Uruguay Round (AAUR) de 1995 jusqu'à 2005. En particulier, nous analysons séparément et en interaction les contingents d'importation, les tarifs sur les importations faites à l'intérieur et au-delà des contingents et la section des engagements laitiers relative aux subventions des exportations. L'analyse jette un éclairage sur les compromis possibles parmi les divers éléments de la libéralisation préconisée par l'AAUR. Une reconduction de l'AAUR jusqu'en 2005 ferait plus que doubler les impacts sociaux du GATT 2000 sur les producteurs et sur les consommateurs dans la plupart des régions, par comparaison au scénario de base. Ces impacts pourraient se chiffrer entre 2 et 5 milliards de dollars. Des calculs modélisés, il ressort que l'Union Européenne resterait lourdement protégée, même après l'extension de l'AAUR jusqu'en 2005 et que ses producteurs laitiers seront ceux qui auront le plus à perdre d'une libéralisation plus radicale du commerce àl'expiration de l'Accord. En revanche, les producteurs laitiers des régions exportatrices à faibles coûts de production, comme la Nouvelle-Zélande, l'Australie et la partie méridionale de l'Amérique du Sud sont ceux qui auront le plus à gagner. Les impacts de GATT 2005 sur le Japan, sur les États-Unis et sur le Canada seraient relativement peu importants. 相似文献
