Tourism certification schemes offer a transitional procedure to a more transparent and sustainable tourism product. Engaging current and previous Green Tourism Business Scheme (GTBS) members in Scotland, this research addresses issues of retention affecting progression of sustainable tourism supply. Quantitative analysis tracking GTBS members over three time points reveals 2% growth but conceals significant flux in membership. Retention was calculated at 66%, where business type analysis discloses distinct issues among accommodation providers with 42% departing the scheme. Decline is greatest among B&;Bs and guesthouses (?61%), where poor and falling recruitment coincides with very poor retention (33%). Our analysis demonstrates that slow growth in membership is primarily a result of enterprises choosing to leave the scheme, rather than poor recruitment. Questionnaires from past and present GTBS members (n = 109) confirm the importance of personal pro-environmental philosophies and perceived business benefits in attracting members, yet anticipated benefits do not always materialise. The main reasons for leaving the GTBS relate to membership cost and unrealised benefits. Lack of scheme awareness, management, criteria, bureaucracy and time commitment were further departure factors. The paper offers some suggestions to address issues and enhance retention leading to sustainable growth among tourism certification schemes.  相似文献

The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic.  相似文献

If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense.  相似文献

THREE SOLITUDES IN CONTRACT: LAW, DATA, AND THEORY   总被引:1,自引:1,他引:0  
This note discusses and contrasts the different perspectives that the law, empirical labor economics and contract theory bring to the study of the employment relationship. Understanding the reasons for these different perspectives should give rise to a better understanding of the employment relationship and more effective labor market policy.  相似文献

Economics students need to be taught that opportunity costsare important for optimal decision making but that sunk costsare not. Why should this be? Presumably these students havebeen making optimal decisions all their lives, and the conceptsshould be easy for them. We show that caring about sunk costscan help agents achieve efficient investments in a simple teamproduction environment. Furthermore, the solution we proposeis uniquely efficient if the environment is sufficiently complex.Hence, in addition to explaining contract form and ownership(Williamson, 1975; Hart, 1995), studies of the holdup problemmay also provide insights into observed behavior in day-todaybilateral bargaining problems.  相似文献

Economic models of contract typically assume that courts enforce obligations based on verifiable events (corresponding to the legal rule of specific performance). As a matter of law, this is not the case. This leaves open the question of optimal contract design given the available remedies used by the courts. This article shows that American standard form construction contracts can be viewed as an efficient mechanism for implementing building projects given existing legal rules. It is shown that a central feature of these contracts is the inclusion of governance covenants that shape the scope of authority and regulate the ex post bargaining power of parties. Our model also implies that the legal remedies of mistake, impossibility and the doctrine limiting damages for unforeseen events developed in the case of Hadley v. Baxendale are efficient solutions to the problem of implementing complex exchange.  相似文献

Harmful non-indigenous species (NIS) introductions lead to loss of biodiversity and serious economic impacts. Government agencies have to decide on the allocation of limited resources to manage the risk posed by multiple NIS. Bioeconomic modelling has focused on single species and little is known about the optimal management of multiple NIS using a common budget. A comprehensive bioeconomic model that considers the exclusion, detection and control of multiple NIS spreading by stratified dispersal and presenting Allee effects was developed and applied to manage the simultaneous risk posed by Colorado beetle, the bacterium causing potato ring rot and western corn rootworm in the UK. A genetic algorithm was used to study the optimal management under uncertainty. Optimal control methods were used to interpret and verify the genetic algorithm solutions. The results show that government agencies should allocate less exclusion and more control resources to NIS characterised by Allee effects, low rate of satellite colonies generation and that present low propagule pressure. The prioritisation of NIS representative of potential NIS assemblages increases management efficiency. The adoption of management measures based on the risk analysis of a single NIS might not correspond to the optimal allocation of resources when other NIS share a common limited budget. Comprehensive bioeconomic modelling of multiple NIS where Allee effects and stratified dispersal are considered leads to a more cost-effective allocation of limited resources for the management of NIS invasions.  相似文献

机票销售对于绝大多数航空公司而言就是圣杯,但是支付流程的重要性——特别是对于依赖于直销的低成本航空公司而言——不能低估。如果正确的票价不能进入航空公司银行账户,那么一切都是空谈。尽管这看上去只是一个简单的流程,获得旅客的信用卡信息然后获得银行授权,但是其中的各种困难并不为外人所知。  相似文献

Labor management practices in Japan are quite different from those in the United States. We begin with the assumption that markets are incomplete, and use recent developments in contract theory to develop a conceptual framework to understand why the differences have been maintained. Our basic message will be that the American and Japanese systems are examples of two different equilibria. The distinguishing feature of these two equilibria will be the extent to which exit is used as a method of contract enforcement. In the United States there is a greater tendency for the use of exit because active markets exist for senior workers. In contrast, there is virtually no market for mid-career workers in Japan. We also discuss the implications of this fundamental difference for the structure of the internal and external labor markets.  相似文献

Most U.S. states have enacted JSL reform, the move from a regime of joint and several liability (JSL) that allows plaintiffs to claim full recovery from any one of multiple defendants to one where defendants are held liable only for the harm they cause. Contrary to previous theoretical work, we show that JSL reform can increase precaution by judgment proof agent by giving “deep pockets” an incentive to reduce their own liability by bringing judgment‐proof agents into court. This result can help explain our empirical findings showing that JSL reform reduces death rates (and hence increase precaution) for many types of accidents. Together, these results highlight the role that litigation costs and judgment‐proof agents play in the functioning of the American tort system.  相似文献
