Preferences for charitable giving in auctions can be modeled by assuming that bidders receive additional utility proportional to the revenue raised by an auctioneer. The theory of bidding in the presence of such preferences results in a very counterintuitive prediction which is that, in many cases, bidders having preferences for charitable giving does not lead to a substantial revenue advantage for an auctioneer. We test this theory and this prediction with a series of experiments. In one experiment we induce charitable preferences exactly as specified in the model to see if bidders respond to them as predicted. We find that they do. We then conduct a second experiment in which the revenue from the auctions is donated to actual charities to verify the robustness of the prediction when charitable preferences are generated by a more natural source and find again that the theoretical prediction holds: even strong charitable preferences do not result in substantial revenue increases to the auctioneer.  相似文献

This study evaluated 967 U.S. CVB websites using a modified Balanced Scorecard (mBSC) approach which assesses website performance with respect to overall technical functionality, customer friendliness and usability, effectiveness of marketing the destination, and information content. Spatial maps were constructed for these four dimensions and overall CVB website performance using ArcMap v.9.2 GIS software. A structural pattern of CVB website performance was obtained using Structural Equation Modeling (SEM). It was concluded that CVB websites primarily need improvement in marketing the destination product. The analysis revealed significant differences in website performance between members and non-members of Destination Marketing Association International (DMAI) as well as regional differences. Study implications for destination marketing organizations and CVB website designers are discussed.  相似文献

This article draws attention to issues about the institutional matrices theory (IMT) as perceived by and raised in the article by F. Gregory Hayden. To clarify the “controversial” points, I structure my response narrative along two lines. First, I present the prehistory of IMT, or X- and Y- theory, including earlier work by scientists related to the concept of institutional matrix. I connect the development of the actual IMT with the period of “perestroika” and the associated market experiments and reforms in Russia and Eastern European countries. One could see that the effects of market reforms in Russia were different in comparison with other countries in economic transition. I show that the institutional approach was accepted as more relevant to understanding the unexpected results in Russian society. I present IMT as a development of the ideas of Karl Polanyi and Douglas North to answer the challenges of explaining the real social and economic processes in Russia, as well as its wider application to a broader range of economic and social situations in different countries. Second, I then present the main IMT theses, giving special attention to the issues as perceived and raised by Hayden. In conclusion, I suggest the possibility of a joint project that combines IMT consideration and the social fabric matrix (SFM) concept of F. Gregory Hayden.  相似文献

Aims: To carry out a cost-utility analysis comparing the cost-effectiveness of levodopa carbidopa intestinal gel (LCIG) with standard of care (SOC) in patients with advanced Parkinson’s Disease (aPD) unsuitable for apomorphine or deep brain stimulation (DBS). LCIG is the only treatment option in this small, but clinically important, population.

Methods: A Markov model with 25 disease states based on disease stage and off-time status plus death. Patients enter the model with aPD spending >50% of their waking day in the off-state. Patients progress through the model in 6-monthly cycles for 20 years to approximate lifetime treatment and capture long-term costs and effects of therapy. Inputs are based on LCIG clinical trials for clinical outcomes and health state utilities, the literature for health state transitions and use UK-based input data wherever possible (drug costs, disease/adverse event management costs, discontinuation rates, mortality rates).

Limitations: Data collection can be challenging in this small, elderly population with advanced disease, therefore some model inputs were estimated, rather than collected directly. It was assumed that a reduction in off-time was the only benefit after the first year of treatment with LCIG; this is a conservative approach, since there may be additional clinical benefits.

Results: There is a considerable incremental gain in quality adjusted life years (QALYs) for patients treated with LCIG of 1.26 QALY with an associated incremental cost-effectiveness ratio (ICER) of £52,110. If the impact on caregivers is included, the ICER reduces to £47,266.

Conclusions: In cases where there is an orphan population, with no alternative treatment options, HTA assessments have a broader decision-making framework and the ICER is interpreted in this context. In the setting of a very small population, with considerable unmet need, LCIG represents value for money, as reflected by funding approval across the UK.  相似文献

Brand defection in a business-to-business financial service   总被引:1,自引:0,他引:1  
This research examines the reasons for brand defection in a business-to-business financial service. Three cross-sectional studies examine customers who ceased using a brand in the previous month. The research shows that about 60% of brand defection occurs for reasons that brand managers cannot influence, such as business closure or head office decisions. Hence, retention strategies can have a maximum success rate of 40%. Furthermore, most defection within this 40% relates to dissatisfaction with fees and charges, or the attractiveness of competitors' offers. These reasons limit what brand managers can do to retain these customers other than just matching competitors' offers. On the other hand, most customers who defect because of price issues or reasons beyond management control still have a positive attitude towards their former brand and are likely to consider this brand for future purchases. Only 4% of lapsed customers defect because of service service-related issues. These customers are less positive about their former brand, compared to other lapsed customers. The research provides implications for investments in customer acquisition versus customer retention.  相似文献

Contemporary organizations are placing greater emphasis on team work in order to meet the challenges of an increasingly turbulent business environment. In this context, the relationship between team member proactivity and overall team performance has been the focus of growing interest among management scholars and practitioners alike. Whereas extant scholarship acknowledges that team member proactivity is different from other forms of proactivity (i.e., individual and organization member proactivity), there is still only limited understanding of the factors that predict team member proactivity. Therefore, this paper extends current scholarship by identifying the individual and contextual predictors of team member proactivity and explaining how, taken together, they jointly influence team member proactivity. Building on these findings, the paper also identifies gaps in the current literature and proposes a model of team member proactivity to be tested in future research.  相似文献

The aim of this paper is to contribute to the vivid political discussion on the consequences of the Russian agricultural import ban on the German export market by quantifying export losses that German agri-food exporters encountered on the Russian market due to the agricultural import ban of 2014. A gravity-type approach is used to measure the sanction effect in a panel of German agri-food exports covering the period from January 1999 to June 2018. The ban effect is disentangled from a sequence of different geopolitically- and economically driven episodes. Once macroeconomic developments of the Russian economy as well as individual stages of decreasing trade cooperation in the preban period are accounted for, the import ban reduced German agri-food exports significantly but was not the major cause. Therefore, a simple elimination of the ban will not be enough to restore trade to the presanctions level.  相似文献

The People's Republic of China has been following a strategy for several decades to encourage its enterprises to invest overseas. Since the liberalization of the Sino-Soviet border in the 1990s, Chinese farmers have been actively engaged in the economy of the Russian Far East (RFE). This article examines Chinese and Russian public relations messages broadcast by media about Chinese-Russian agricultural cooperation that use different arguments, methods of reasoning, and points of view. There is a clash of different national management methods. Legislation applying to Chinese working in Russia has been erratic and unstable, and that makes cooperation more challenging. The concepts of environmental protection and obedience to the law are understood differently by Russians and by Chinese. Cross-cultural management differences affect the way people on both sides interpret institutions, interactions, and the ability to trust third parties. There are different values and priorities expressed by Russians and by Chinese when it comes to development of rural areas in the RFE.  相似文献

The dual problems of high and rising medical care expenditures and substantial differences in spending across geographic regions have long plagued the US health care system. We provide new evidence to explain why some states and regions of the country spend much more on medical care than others, and why health care spending for the nation as a whole has been growing rapidly over the last several decades. To do this, we estimate a health care spending panel data model using annual data on all 50 states for the period 1993–2009. Our model includes a number of socio-economic, health care provider, lifestyle and environmental variables that past studies indicate may affect the level or growth of aggregate health care spending. We exploit the time effect component of our model to obtain an upper-bound estimate of the effect of advances in medical technology. Our findings indicate that the most important factors influencing the level of spending are availability of providers, income, excessive alcohol consumption, Medicaid coverage, HMO health plans and the proportion of the population elderly and African-American. The principal drivers of growth have been the continual introduction of new medical technologies, and the growth of providers and income.  相似文献

Should asset testing be used in means‐tested programs? Focusing on Medicaid, we show that in the asymmetric information environment, there is a positive role for asset testing. Our tool is a general equilibrium model with heterogeneous agents. We find that 23% of Medicaid enrollees do not work in order to be eligible. These distortions are costly: If Medicaid eligibility could be linked to (unobservable) productivity, this results in substantial welfare gains. We show that asset testing can achieve a similar outcome when asset limits are allowed to be different for workers and nonworkers.  相似文献
