We determine the value of monitoring perishable freight in-transit for a single vehicle traveling from an origin to a destination. We develop a computationally practical approach for determining the optimal expected cost function and an optimal policy, based on an infinite horizon partially observed Markov decision process model. Structural properties of the optimal expected cost function and optimal policy are determined. These results can lend insight when deciding whether to acquire the capacity to monitor freight status in transit and what actions to take, based on the data from the in-transit monitoring, that optimally increase expected supply chain productivity. 相似文献

This study compared the perceptions of various important job applicant characteristics, job characteristics and job benefits between 107 corporate recruiters and 191 business undergraduates in Singapore. Results indicated significant incongruence between recruiter and student perceptions of a large number of job characteristics and benefits. However, perceptual differences were less extensive in the case of applicant attributes. The implications of these findings, and suggestions for greater perceptual congruence between recruiters and applicants, are discussed. 相似文献

This discussion explores a number of ways that more effective risk management, corporate governance, and communication with investors can help companies increase their effciency and long-run value. According to one of the panelists, recent surveys of corporate directors suggest that companies should devote more time and attention to three issues—strategy, risk management, and succession planning—and that strategy and risk are the “flipsides of the same coin.” As the panelist argues, “You can't talk about strategy without talking about what risks you're going to take—and what risks you decide to take has to depend on the core competencies that drive the corporate strategy.” In addition to making risk management a critical part of corporate strategy, another notable recommendation is to communicate a company's strategy and business plan as clearly as possible to investors, with the aim of attracting more sophisticated, long-term shareholders. Contrary to popular belief, such a group may well include some hedge funds and other activist shareholders. According to a newly released report on shareholder activism (produced and cited by another panelist), corporate boards should work harder to identify and engage the “largest 10 shareholders in the organization,” with the ultimate goal of cultivating a shareholder base that buys into the company's strategy. 相似文献

This study uses international asset pricing models to investigate the link between the quality of government institutions and the performance of global stock markets. The results demonstrate a significant positive association between stock market performance measures and the quality of the institutional environment. Performance measures examined for the cross-section of countries were the average monthly stock index excess returns and the Sharpe ratio. All measures of performance were adjusted for global and local risk factors known to explain their international variation. The quality of governance is also found to be negatively associated with stock market total risk and idiosyncratic risk, consistent with the notion that stable institutions are linked to reduced variations in equity returns. These findings suggest countries with better-developed governance systems have stock markets with higher returns on equity and lower levels of risk. The results lend support for the view that a precondition for financial market development is the improvement of the institutions which govern the process of exchange. 相似文献

Using samples from the U.S. and Puerto Rico, we examine cross-cultural differences in cultural value dimensions, and relate these to act and rule utilitarian orientations, and ethical decision making of business professionals. Although these places share the same legal environment, culturally they are distinct. In addition to tests of between-group differences, a model in which utilitarian orientation mediates the influence of cultural values on ethical decisions was evaluated at the individual level of analysis. Results indicated national culture differences on three cultural values, but no between-group differences on utilitarian orientations and ethical decisions. Significant indirect effects were found; act utilitarian orientation mediated the effects of two values activity orientation and universalism on ethical decision making. Implications for international management practices and business ethics are discussed. 相似文献

In this research note, volatility clustering modeling framework is used to examine the determinants of hotel room rates in Singapore. Using monthly data from January 1985 to June 2009, GARCH-M(1, 1) is identified as the appropriate model used to capture volatility clustering. The results suggest that total inbound tourists and economic performance have positive effects on hotel room rates. The main findings are (a) the occurrences of terrorist activities in the neighboring countries have negative impacts and (b) the volatility of hotel room rates has a positive effect, on hotel room rates. 相似文献
