Multichannel retailers offer shoppers the possibility to cross channels to complete their shopping process. Multichannel retailers, unlike pure online sellers, offer shoppers multiple contact points to experience the brand. Also, multichannel retailers can leverage the trust and attachment to their brands that has been built with their offline presence to drive customers to buy online. Our paper explores the role of the customer relationship with the brand, with variables such as brand trust, brand attachment and length of brand relationship, as drivers of loyal behaviours towards the online channel. We compare the impact of these variables with those of the technology acceptance model. Multiple linear regression analysis is applied to data collected through a survey answered by 1533 multichannel retail shoppers in two product categories (apparel and consumer electronics) in two countries (UK and Spain). Our findings show that both brand trust and brand attachment have a positive impact on loyal behaviours towards the online channel, and that different loyalty behaviours, i.e. purchase intentions, word of mouth and electronic word of mouth are explained by different variables.  相似文献

Countries whose cities host the Summer Olympic Games increase significantly their success during the competition. We study whether such effect is lasting or not. We compute the effect of hosting on the total number of medals in the subsequent games. To confront the issue that the selection of the host city is endogenous, we use a natural counterfactual: countries whose cities also bid for the Olympics but were not selected by the International Olympic Committee. In all cases, we find that Olympic success on medals fades away immediately after hosting.  相似文献

This research introduces the multi-product capacitated facility location problem with general production and building costs (MP-CFLPGC). The MP-CFLPGC extends previous problems found in the literature by including multiple products and general production and building cost functions that allow the modeling of different behaviors like economies of scale and congestion. The MP-CFLPGC is formulated as a mixed integer linear program (MILP). To evaluate the performance of the proposed formulation we analyze the results of a commercial optimizer on a set of 288 randomly generated test instances that resemble the Colombian cement industry supply chain. After one hour the optimizer achieved an optimality gap of 1.0 % or less in 55 % out of the 288 test instances. On average the optimality gap was 3.57 %. Additionally, we propose a randomized mathematical-programming-based heuristic for the test instances where the MILP formulation presents significantly high optimality gaps.  相似文献

The Mexican peso has shown long periods of tranquility that suddenly give rise to short volatile periods. We characterize this exchange rate process by estimating a series of regime switching regressions and comparing the different specifications as pioneered by Meese and Rogoff [J. Int. Econ. 14 (1983) 3]. We find evidence for two clearly identified regimes: one with an appreciating trend and low volatility, and another with large depreciations and high volatility. We use the estimated model to explain the bias implied in the peso forward market. Finally, we show that duration dependence or fundamentally driven transition probabilities do not improve the model's forecasting power.  相似文献

Multiple objects may be sold by posting a schedule consisting of one price for each possible bundle and permitting the buyer to select the price-bundle pair of his choice. We identify conditions that must be satisfied by any price schedule that maximizes revenue within the class of all such schedules. We then provide conditions under which a price schedule maximizes expected revenue within the class of all incentive compatible and individually rational mechanisms in the n-object case. We use these results to characterize environments, mainly distributions of valuations, where bundling is the optimal mechanism in the two and three good cases.  相似文献

This article analyses the impact that entrepreneurial activity has, from the economic point of view, on a regional economy (Andalusia), based on a Social Accounting Matrix linear model. Moreover, to measure entrepreneurship at regional level, it is defined what can be considered an entrepreneurial initiative company from a quantitative point of view. The results obtained, in terms of Production, GDP and job creation, show how entrepreneurship, in the case of Andalusia, contributes to the sustainability of the economy, its growth and, above all, the reduction of unemployment in the short term.  相似文献

The paper deals with optimal portfolio choice problems when risk levels are given by coherent risk measures, expectation bounded risk measures or general deviations. Both static and dynamic pricing models may be involved. Unbounded problems are characterized by new notions such as (strong) compatibility between prices and risks. Surprisingly, the lack of bounded optimal risk and/or return levels arises for important pricing models (Black and Scholes) and risk measures (VaR, CVaR, absolute deviation, etc.). Bounded problems present a Market Price of Risk and generate a pair of benchmarks. From these benchmarks we introduce APT and CAPM-like analyses, in the sense that the level of correlation between every available security and some economic factors explains the security expected return. The risk level non correlated with these factors has no influence on any return, despite the fact that we are dealing with risk functions beyond the standard deviation.  相似文献

For a small tariff-imposing country, within the standard two-commodity two-factor model of international trade, this paper reconsiders the implications of an inflow of capital from abroad. When the host country continues to import the capital-intensive good while remaining incompletely specialized, the analysis shows that the capital inflow must reduce host-country welfare, assuming that the foreign capital receives the full (untaxed) value of its marginal product. Under other circumstances considered, however, the inflow may have different consequences for welfare.  相似文献

The economic impacts of animal disease outbreaks have been widely discussed in the literature. Most authors have centred their attention on estimating the direct costs. Recent studies have shown that the indirect economic effects might lead to equal or even higher welfare losses. This study aims to contribute to this field of research by assessing the effect of an animal disease outbreak on food market price dynamics in Mexico, accounting for the potential effect of an antitrust intervention. We employ a regime‐dependent vector error correction model and a connected scatterplot analysis. The results show that both the outbreak and the antitrust intervention caused structural breaks in food market price dynamics between producers and consumers, reflected in an increase in the absolute component of the marketing margin, with serious food security implications.  相似文献

We study individually rational rules to be used to allot, among a group of agents, a perfectly divisible good that is freely available only in whole units. A rule is individually rational if, at each preference profile, each agent finds that her allotment is at least as good as any whole unit of the good. We study and characterize two individually rational and efficient families of rules, whenever agents' preferences are symmetric single-peaked on the set of possible allotments. Rules in the two families are in addition envy-free, but they differ on whether envy-freeness is considered on losses or on awards. Our main result states that (a) the family of constrained equal losses rules coincides with the class of all individually rational and efficient rules that satisfy justified envy-freeness on losses and (b) the family of constrained equal awards rules coincides with the class of all individually rational and efficient rules that satisfy envy-freeness on awards.  相似文献
