We consider a class of production–investment models in discrete time with proportional transaction costs. For linear production functions, we study a natural extension of the no‐arbitrage of the second kind condition introduced by Rásonyi. We show that this condition implies the closedness of the set of attainable claims and is equivalent to the existence of a strictly consistent price system under which the evaluation of future production profits is strictly negative. This allows us to discuss the closedness of the set of terminal wealth in models with nonlinear production, functions which may admit arbitrages of the second kind for low production regimes but not marginally for high production regimes. 相似文献

Consumers are increasingly searching for beautiful memories. Memory is not solely the work of the mind retrieving a “true” past. People represent their unique past to (re)construct their identity and seek social links with others who share the remembered events. Through visual analysis of the web posting of war photographs by Vietnam veterans, this paper explores how people consume representations in remembering, reconstructing identities and building a mnemonic community. The analysis suggests that individual remembering is nested within collective remembering. A conceptual framework viewing remembering as mediated action helps to explain how consumers use representations in remembering. This process is carried out not only by individuals but also by cultural institutions. American Vietnam veterans use consumer products including private photographs, movies, books, travel trips and the Internet as tools to assist in the on‐going process of remembering. They add their own voice into the social representation system to create representations that further express who they are and to connect with their community. The constructed memory shapes consumers' present. This in turn modifies their representation of their pasts which become involved in changing the larger social representation system. 相似文献

ABSTRACT This article explores the use of marketing metrics by a sample of Vietnamese firms, providing an example of the use of marketing metrics in a “transition” economy as it grows and becomes more market and marketing driven. The analysis reports usage frequency and then develops a set of “correlation chains” linking firm characteristics, metric use, and various indicators of performance. Vietnamese managers generally report that several types of metrics are used. Ownership structure and industry also impact which metrics are utilized. An initial assessment of chains relating metric use to firm performance indicates that the impact is complex and indirect. 相似文献

ABSTRACTPurpose: Realizing the existence of information asymmetry in export markets and the use of signals to distinguish high-qualified sellers from low-qualified sellers, this study investigates the effects of signal consistency and signal clarity on exporter credibility, and subsequently, importer relationship intention.Methodology: Using a survey data set collected from a systematic sample of 418 Vietnamese importers, the authors tested a model hypothesizing the impact of signal consistency and signal clarity on exporter credibility, and subsequently, on importer relationship intention.Findings: The authors found that signal consistency and clarity have a positive impact on exporter credibility. Signal consistency also enhances the level of signal clarity. They also found that exporter credibility underlies importer relationship intension.Research Implications: Under the condition of information asymmetry, importers face difficulties in identifying and evaluating the best supplier among available suppliers in order to make the most appropriate selection decision. The findings confirm that signal clarity and consistency can help exporters to overcome such problems. Exporters should ensure that all signals sent to importers are clear and consistent over time to encourage importers to build long-term business relationships with them.Contributions: The findings of this study add to the literature on signaling in exporter–importer relationships and can serve as an initiation for further research in the area in transitioning economies. 相似文献

The concept of fairness has received great attention in consumer behavior research lately. However, the focus of these studies has mainly been the understanding of fairness in terms of pricing rather than exploring the consumers’ perceptions of fairness itself. This study explores the consumers’ perceptions of fairness as an outcome of a retailer’s marketing tactics. Based on 36 in-depth interviews this study submits a conceptualization of retail fairness from the consumers’ point-of-view. The concept of retail fairness constitutes of three dimensions and nine sub-dimensions, expanding our knowledge of the construct. The study posits a crucial link between increased honesty, ethical, and moral behavior and the understanding of retail fairness. Theoretical and managerial implications are discussed. 相似文献

It is shown that the stochastic investment rule for the price-setting monopolist facing random demand differs from the deterministic rule, due to the presence of the covariance of the marginal utility of profits and the MRTS between capital and labor. For the risk-neutral quantity-setting monopolist, the optimal current investment under random demand is shown to be greater than that under deterministic conditions, given that production technology is of the Cobb-Douglas type with constant returns to scale. When random wages and prices follow first-order autoregressive schemes, the risk-neutral competitive firm's current investment level is shown to be at least equal to that under certainty. 相似文献

Investigation of factors affecting the diffusion of mobile telephone services: An empirical analysis for Vietnam 总被引:1,自引:0,他引:1
This paper analyzes the diffusion of mobile telecommunications services in Vietnam and examines how telecommunications regulation and potential substitute/complement services affect the growth of the number of mobile telephone subscribers. Using a logistic diffusion model, it is found that fixed telephone services are a complement while data services have a negative relation to mobile telephone services in Vietnam. As for regulation, the policy of introducing competition has been found to be the most effective in influencing the adoption of mobile services. Another important result is that the estimated potential market is roughly 76% of the total population. The findings suggest that suitable regulation that guarantees competition in the mobile telecommunications market in a developing country such as Vietnam is one of the most important factors for a positive diffusion process. 相似文献

Mature consumers have long been recognised as an important segment of market that no marketers of financial-service providers could ignore. The segment itself, however, is not homogeneous. Our study further segments the market basing on income and contrasts the differences between upscale mature consumers and lower scale ones in terms of their preference and patronisation for financial services. The study based on two large-scale studies designed to generate information that would fill gaps in our existing knowledge about upscale older consumers. Implications are discussed for marketers of financial services to fine-tune their differentiation strategies. 相似文献

Summary This paper considers the prediction of the sample mean by extreme order statistics when the population distribution is known.
The predictor and its mean square error are found. The problem is studied in details for the normal model. 相似文献
