For enterprises, it is imperative that the trade-off between the cost of inventory and risk implications is managed in the most efficient manner. To explore this, we use the common example of a wholesaler operating in an environment where suppliers demonstrate heterogeneous reliability. The wholesaler has partial orders with dual suppliers and uses lateral transshipments. While supplier reliability is a key concern in inventory management, reliable suppliers are more expensive and investment in strategic approaches that improve supplier performance carries a high cost. Here we consider the operational strategy of dual sourcing with reliable and unreliable suppliers and model the total inventory cost where the likely scenario lead-time of the unreliable suppliers extends beyond the scheduling period. We then develop a Customized Integer Programming Optimization Model to determine the optimum size of partial orders with multiple suppliers. In addition to the objective of total cost optimization, this study takes into account the volatility of the cost associated with the uncertainty of an inventory system. 相似文献

Experiential learning is used to address the abstractness of classroom discussion and motivate long-lasting learning. The aims of this study were to measure the effects of a tourism service-learning course on the development of students’ generic competencies and to evaluate the influence of experiential learning on hospitality and tourism education. Preproject and postproject self-administered surveys and postproject reflective journals were completed by students enrolled on a service-learning course entitled Ecotourism in Rural and Developing Regions. The majority of the students were found to value the service-learning course, particularly a service project conducted outside the classroom setting, which made them aware of the needs of the underprivileged within the service community. The students also showed significant improvements in their generic competencies, specifically their teamwork and sense of social responsibility. 相似文献

This study investigates the tax efficiency of actively managed equity funds by conducting a previously unaddressed natural experiment. Specifically, we examine whether asset sales were timed to take advantage of the introduction of a substantial discount to realized capital gains when the holding period was at least 1 year. Institutional equity fund management in Australia is principally focused on the pre-fee and pre-tax performance surveys of leading asset consultants. Given this industry setting, our study is important because tax efficiency is not accounted for directly in the reported performance numbers, and is thus opaque. We find that active fund managers overall have significantly increased the proportion of long-term capital gains realized after the change in taxation code, although there are significant variations across funds. We also find that active fund managers realize more long-term gains on both large capitalization and low volatility stocks. 相似文献

There is increasing recognition of the potential contribution of local small and medium enterprises (SMEs) towards employment and economic growth in Singapore. Unfortunately, SMEs tend to have a high mortality rate. A survey was conducted among owners or managers of local SMEs to identify factors perceived as important in affecting business failures. The research results indicate that endogenous factors were viewed by respondents as more critical in causing SME failures than exogenous factors. Important exogenous and endogenous factors in specific areas were identified.Lau Geok Theng is Senior Lecturer, Department of Marketing, National University of Singapore, 10 Kent Ridge Crescent, Singapore 0511, tel: (65) 772-3179, fax: (65) 779-5941.

Abstract. Large differences exist between the official United States and Chinese data on trade balances between the two countries. In this paper, four adjustments are made to the export and import data of the two governments: (i) freight along side (f.a.s.)-free on board (f.o.b.) and cost, insurance and freight (c.i.f.)-f.o.b. conversions; (ii) re-exports through Hong Kong (and elsewhere); (iii) re-export markups; and (iv) trade in services. After adjustments, our best estimate for the 2005 bilateral trade balance is $US170.7 billion, in China's favour, which is much larger than the official Chinese balance of $US114.2 billion but also much smaller than the official US balance of $US201.6 billion. 相似文献

In two previous papers by the same authors the data basis for the trade flows and the export prices in the Pacific Basin has presented and documented. In this third report the changing pattern of Pacific Basin trade over the period 1955–1975 is analyzed, using as tools export growth decomposition indexes, trend analysis, and regression analysis of the price elasticity of import market shares. 相似文献

Firms in transitional economies are learning to develop strategies to exploit new market opportunities though bounded by their lack of market experience and resources as well as institutional and cultural heritage. This paper examines the managerial orientations of top managers in the transitional economy of China by focusing on a firm's team and organizational resources. Specifically, the following antecedents motivate a firm to put more emphases on strategic orientations: the firm has an effective top management team, strong managerial competences, and when the firm has ample endowment of slack resources, social network, and support from the institutional environment. Empirical results support that team orientation, managerial competence, social network, and local institutional support are instrumental in developing market-focused strategic orientations. In addition, strategic orientations with heavy emphases on overall low costs and product innovation relate to higher firm performance. 相似文献
