While at one time counterfeit products were largely restricted to watches, designer apparel, and movies, today counterfeiting is a major problem in such diverse product categories as pharmaceuticals, automotive parts, and computer software. There are four distinct types of counterfeits: knockoffs, counterfeits that are reverse engineered from genuine goods, goods produced by outsourced suppliers on “third shifts,” and goods that do not meet a manufacturer's standards but are not properly labeled as seconds or destroyed. The quality of some counterfeits is so good that some major retailers have unknowingly purchased counterfeits. But while there are new forms of counterfeit goods, there are also new strategies for combating counterfeiting. This article describes how to detect and reduce counterfeiting activity, via a plan which consists of four steps: (1) developing early warning signals of counterfeiting; (2) budgeting to monitor, deter, and remove counterfeits; (3) using demand-side strategies to deter counterfeiting; and (4) using supply-side strategies to deter counterfeiting.  相似文献

Most properties of the classical general equilibrium model without externalities fail to extend to the wildest forms of consumption externalities. The recent interest for wealth concerns, a kind of externality associated with herding behavior and other-regarding preferences, motivates a study of the general equilibrium exchange model with those externalities. The diffeomorphism of the equilibrium manifold with a Euclidean space, the smoothness and properness of the natural projection and its non-zero degrees are shown to hold true for endowment spaces with variable total resources. Other properties of the classical exchange model without externalities are fragile in the sense that they do not resist the introduction of wealth concerns even in models where consumers preferences are represented by the simplest forms of utility functions like the log-linear (or Cobb–Douglas) functions. The most notable fragile properties are the uniqueness and regularity of equilibrium at equilibrium allocations and the stability of no-trade equilibria.  相似文献

Despite the importance of slow tourism, studies on slow tourists' decision-making processes are rare. The current study extends the theory of planned behaviour (TPB) by including authentic perception (AP) and environmental concerns (ECs) to explain the formation of behavioural intentions. The study also contributes by comparing its extended model with the original TPB and identifying salient belief items through a focus group and literature review. The results of a structural equation analysis revealed that the data fitted the extended model well and that the inclusion of the critical new constructs in a slow-tourism context significantly enhanced the prediction of behaviour intentions. The results also indicated that attitude, subjective norms, perceived behaviour control, and AP significantly contributed to forming the intention to participate in slow tourism. However, the influence from ECs to behavioural intentions was demonstrated to be insignificant. This study advances our understanding of tourists' decision-making processes in that these slow tourists are more likely to choose an “authentic”, rather than “environmental”, destination.  相似文献

This research responds to calls for research on the devastating impact of the Covid-19 pandemic on the hospitality industry by investigating how hotel managers are designing safe customer experiences. Specifically, this study examines the measures adopted in high-end and luxury hotels and identifies the effects of such measures on the intended (or planned) experience. Based on thematic analysis of interviews with hotel managers, this study identifies seven safety measures: hygiene and protection, internal work reorganization, servicescape reorganization, investments in technology and digital innovations, customer wait time reorganization, staff training, and updated communication. These measures are expected to affect the intended experience in terms of reassurance, quickness, intimacy, and proximity, as emerged from correspondence factor analysis. Based on these results, this research proposes a model for safe customer experience design and suggests practical implications to help hotel managers formulate strategies aimed at customer experience creation under safe conditions.  相似文献

This study was conducted in the midst of a surge of undocumented immigrants into a popular seasonal migrant destination in the U.S. and the subsequent state response of adding security forces. Factors examined include the effects of the role of media in shaping perceptions about security forces, perceptions about security force effectiveness, perceptions of undocumented immigrants and political orientation. The study of 413 respondents found that attitudes toward undocumented immigrants affect felt safety in the region, likelihood of recommending and returning to the region. Perceptions of the effectiveness of the security forces were important in affecting likelihood of recommending the region to others but not return intention. These and other findings contribute significantly to the scant research on both effectiveness of crises management responses and on effects of perceptions of undocumented immigrants on traveler behavior.  相似文献

We investigate whether market makers with inventory concerns are compensated with subsequent monthly returns in the cross‐section. We find a significant negative relation between order flows and monthly returns, “the order flow effect,” suggesting that market makers lower prices for stocks with sell order flows and demand a reward in the form of higher expected returns. Further, the order flow effect is stronger for high‐volatility or high‐volume stocks for which market makers have serious inventory concerns. Funding liquidity of market makers also affects the order flow effect. Finally, our finding is independent of existing regularities and robust to the decimalization.  相似文献

The purpose of this research was to examine the factors that underpin risk perceptions for meat hazards and assess the degree to which these perceptions reflect overall concern. It also sought to identify any differences that exist in information use. A total of 238 meat customers were surveyed in Cork, Ireland. An analysis of consumer perceptions revealed a two-factor structure, 'dread' and 'unknown', similar to Slovic (1992). A perceptual map of the various hazards associated with meat clearly highlighted different groups of hazards and the differing perceptions associated with them. There were groupings between BSE, E-coli and Salmonella, antibiotics, growth hormones and genetic modifications, and saturated fats and cholesterol. Cluster analysis highlighted the differences in attitudes towards meat hazards across the sample population. However, an analysis of the demographic and behavioural variables found no distinguishable features across the identified segments, except in their use of written information. The butcher, quality assurance (QA) marks, country of origin and labelling were identified as the most helpful risk relievers. However, no significant differences were identified between perceived helpfulness and level of perceived 'dread' and 'unknown'. Use of written information by consumers (labels, quality marks and information brochures) was significantly related to their overall concern about hazards.  相似文献
