The Effect of Concept Formulation on Concept Test Scores 总被引:1,自引:0,他引:1
While concept testing is a mainstay of the new product development process, there is little empirical evidence on the variation in consumer responses due to alternative concept formulations, particularly for those tests undertaken early in the product development process. The present study addressed this gap in the literature by using a split sample mail survey to compare stripped, embellished, and visual concept formulations for five heterogeneous product concepts. It was found that respondents' answers to attitude and purchase intention questions showed only minor variation with different formulations of the concept test statement. It also was found that the ranking of the concepts showed no substantial changes across the different formulations. Therefore, the type of concept statement formulation may not be that important, at least for early ranking tasks performed before experiential prototypes are available. Early concept tests therefore may be carried out using stripped concept statements. This may reduce costs, allowing organizations to undertake early concept testing more frequently across a wider range of products. 相似文献

Transition matrix techniques are used to relate the past and present performance of pension fund portfolios. In particular, funds are ranked to study the tendency of portfolios to remain in the same quartile of the ranking as they were in the previous period. For raw returns, funds in both of the top quartiles are found to be more likely to remain in the same quartile than would be expected by chance. This result can be taken as limited evidence for the consistency of performance. Similar systemic effects are observed on a risk-adjusted basis. There appears to be clear evidence that some fund managers can offer a degree of consistent good performance. 相似文献

Economic Analysis for the UK National Ecosystem Assessment: Synthesis and Scenario Valuation of Changes in Ecosystem Services 总被引:1,自引:0,他引:1

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions. 相似文献

Socioeconomic predictors of forest use values in the Peruvian Amazon: A potential tool for biodiversity conservation 总被引:1,自引:0,他引:1
Conservation is a crisis discipline requiring rapid action with limited funds. This study examines the potential of socioeconomic variables to predict forest use values. If natural resource use can be predicted from socioeconomic data, conservation planners could rapidly identify and focus conservation programs on the sectors of local populations that most intensively utilize local flora and fauna. Families in three communities in the northern Peruvian Amazon were surveyed over a 6-month period. Data were collected on use of flora and fauna from six locally determined use categories (food, medicine and poisons, wood, weavings, adornments, and “other”) in forest types of three age classes (fallow fields—very young forests, young secondary forests, and old secondary forests). Forest use values were the dependant variables calculated in $/ha/year. Socioeconomic variables included: age, education, family size, residence time, land worked, land owned, number of fishing nets, chickens, pigs, cows, and/or mules owned (all proxies for productive assets), and level of ecological knowledge (ability of informants to correctly identify forest species and answer basic questions about their biology). Ordinary least square multiple regressions were run independently for each forest type. Regressions were also run separately for the two most valuable use categories, food and wood. Low R2 adjusted values (all < 0.3) reflect the difficulty in predicting human behavior due to confounding variables and complex interactions. Residence time and a household's community of residence were the most significant predictors of forest use values. Households in Vista Alegre, the community with the highest density of people and smallest landholdings per household, extracted the highest value of forest products per hectare. The longer a family stayed in any community the higher the value of forest goods they extracted. If families that lived in an area longest are the most intensive extractors of forest products, they should be a major focus for conservation programming. In addition, the higher value of products extracted from forests by some families may make them more open to strategies seeking to protect long-term viability of the resources they utilize. The importance of residence time also indicates that planners need to account for changes in the resource use patterns of stakeholders over time. 相似文献

This comment reviews the meaning and significance of the econometric results relating to money demand in Singapore in a paper by Daquila and Phua (1993). I argue that there are a number of confusions and faults in their analysis that could account for their results being incompatible with earlier studies and with monetary events in Singapore. An explanation of their perplexing findings is offered, simple re-estimates are made to justify this point and then some implications for economic methodology and research are offered. 相似文献

A number of pertinent questions on regional trade and food security in southern Africa is addressed in this paper, namely: Should a country go it alone or should it belong to a regional trade bloc? Within the SADC region, should countries be content to be cereal importers? How can free trade be phased in? How can intra-SADC trade be expanded? Potentially sensitive agricultural products are listed and the sensitivity in grain milling and cereals is discussed in detail. The major conclusion is that trade in the region can contribute substantially to provide improved food security. There is also considerable scope for greater intra-regional trade in grain and other food products, and for greater cross-border investment in agriculture and agro-industry. 相似文献

Regulators have long been interested in protecting consumers borrowing for a home as it is likely the single greatest financial obligation they will undertake. In this paper we examine the approach taken in Australia to mandating the disclosure of simple comparison data to reduce the complexity involved in the home loan decision. This article highlights that while the form of the legislated disclosure significantly improves decision accuracy, the failure of the regulator to account for the consumer's purchase behavior and lenders' motivations has undermined its effectiveness. We provide a number of recommendations for how to rectify these failings, principally that regulators need to consider the role of borrower information search and lender motivation as part of any regulatory reform. 相似文献

This paper reviews the National Parks and Access to the Countryside Act 1949 fifty years since its enactment. The Act is assessed in the light of fifty years of access policy and within the present context of political debates and manoeuvres over the ‘right to roam’. It is concluded that benevolence is still the prevailing attitude towards access provision, maintaining as it does the scope for alternative freedoms and opportunities to exploit land for consumptive practices such as leisure and recreation. As such, it is argued that the notion of the gift (Mauss, 1990) continues to dominate the provision of countryside access in England and Wales. 相似文献
