Water marketseither formal or informalcan be anefficient method for reallocating scarce water supplies. Atthe same time certain constraints can raise the transactioncosts of trading water. This paper reviews the conditions necessaryto establish successful water markets, identifies potentialproblems, and offers mitigating strategies. It also uses examplesof several informal and formal water markets already in operationto illustrate these problems and the solutions to them. 相似文献

We test the ability of analyst characteristics to explain relative forecast accuracy across legal origins (common law versus civil law). Common‐law countries generally have more effective corporate governance mechanisms, including stronger investor protection laws and inputs provided through higher‐quality financial reporting systems. In this type of environment, we predict that analysts with superior ability and resources in common‐law countries will more consistently outperform their peers because appropriate market‐based incentives exist. In civil‐law countries, where the demand for earnings information is reduced because of weaker corporate governance mechanisms and lower‐quality financial reporting, we predict that analysts with superior ability will less consistently provide superior forecasts. Results are consistent with our expectations and suggest an association between legal and financial reporting environments and analysts' forecast behavior. 相似文献

There is considerable evidence that trading volume and volatility are positively related and that exchange seat prices are largely a function of trading volume. This article examines whether changes in seat prices at the Chicago Board of Trade (where stock index and interest rate futures account for the vast majority of trading volume) are useful in predicting changes in interest rate and stock market volatility. Exponential GARCH and transfer function models are used to demonstrate the power of changes in CBOT seat prices in predicting changes in interest rate and stock market volatility. © 2008 Wiley Periodicals, Inc.

Natural disasters often result in large numbers of evacuees being temporarily housed in schools, churches, and other shelters. The sudden influx of people seeking shelter creates demands for emergency supplies, which must be delivered quickly. A dynamic allocation model is constructed to optimize pre-event planning for meeting short-term demands (over approximately the first 72 h) for emergency supplies under uncertainty about what demands will have to be met and where those demands will occur. The model also includes requirements for reliability in the solutions – i.e., the solution must ensure that all demands are met in scenarios comprising at least 100α% of all outcomes. A case study application using shelter locations in North Carolina and a set of hurricane threat scenarios is used to illustrate the model and how it supports an emergency relief strategy. 相似文献

This article is an introduction to the special issue from the 4th Global Entrepreneurship Monitor Research Conference held at Imperial College Business School, London, in 2010. The article has two objectives. The first is to summarize the history of the GEM consortium, some of the contributions that it has delivered, and some challenges and opportunities ahead. The second is to present a summary of the papers in the context of the utility of GEM data in comparative entrepreneurship research. 相似文献

Confidence in your own profes- sional judgement; that's one goal all internationally-minded business executives need to embrace.Far too often, management teams spend a great deal of time and energy looking for “outside solutions”, or transplanting foreign business models into their strategic plans (which may or not be suitable for the context). Instead, sometimes the ‘best practice' might be the one closest at hand; one's own orofessional iudgement. 相似文献

We revisit Andrew Pettigrew's seminal ‘Context and action in the transformation of the firm’, first published in this journal in November 1987. In doing so, we not only review Pettigrew's contributions, but contextualize these with respect to adjoining strategy scholarship. Our discussion concludes with some novel, and fairly speculative, ways forward, designed to advance strategy scholarship. Working with the ideas contained in Pettigrew's article and drawing on insights from institutional entrepreneurship, we make a case for the processualization of strategy content research. This allows us to add the issue of effectiveness of strategy practices to current strategy‐as‐practice research while arguing for a further humanization of strategic management. 相似文献
