Drawing upon the cost–benefit framework and trust mechanism as a risk reducer, this study examines the influence of brand factors and source credibility on branded product information Web searches. The online survey was conducted within the pre-purchase context of digital camera brands. The results revealed that brand factors did not influence overall branded information search efforts. However, brand trust and source credibility appeared to influence the different types of online information sources sought.  相似文献

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the corresponding factor loadings. Classical identification criteria are applied and integrated into our Bayesian procedure to generate models that are stable and clearly interpretable. A Monte Carlo study confirms the validity of the approach. The method is used to produce interpretable low dimensional aggregates from a high dimensional set of psychological measurements.  相似文献

A new study reveals that U.S. companies face a troubling brain drain: Fifty-two percent of female scientists, engineers, and technologists abandon their chosen professions. If companies understand why women drop out, however, they can create targeted interventions and head off a talent shortage.  相似文献

This research aims to examine the daily return generating processes for country-specific funds in five east-Asian countries for the period 1995-2000. The effects of component returns and their volatility on the dollar denominated returns and volatility of U.S., international investors and the effects of exchange rate regimes on risk and return are also evaluated. The GARCH-M model is adopted, without the restrictive assumptions of linearity, independence, and constant conditional variance. The time frame, 1995-2000 captures a 30 months period prior to these East Asian countries aborting exchange rate stabilization/intermediate exchange rate regimes in response to the currency crisis. The decomposition of returns to holders of country-specific equity funds into the component returns due to changes in the exchange rate and the returns valued in the fund's foreign currency during a period of crisis provides additional information. This research provides evidence of the importance of examining component returns. With regards to the effects on volatility, both the conditional variances associated with the exchange rate returns and the returns denominated in the foreign currencies show some importance, especially the conditional variances associated with the returns denominated in the foreign currencies. With regards to the effects of return component, the exchange rate returns have a greater effect on the fund returns than foreign currency dominated returns.  相似文献

This paper investigates the roles of comparative advantage and market size in the international location of manufacturing production. Building on the conventional Helpman and Krugman (1985) general equilibrium framework, our analysis extends the present literature by incorporating both effects in the same model, while allowing trade costs to vary almost continuously from autarky to free trade. The main result of our exercise is that market size effects offset comparative advantage if countries have similar factor proportions. A large country with a slight comparative disadvantage in manufacturing production may thus be a net exporter of manufactures. A small country with the same comparative disadvantage would be a net importer of manufactures. When countries are very dissimilar in their relative factor endowments, land-abundant countries specialize in the production of food, irrespective of market size, if manufactures are a labour-intensive sector. Labour-rich countries of any size are manufacture cores. However, land-abundant countries with large markets can sustain a domestic manufacturing industry until trade costs are very low, and in some cases only specialize in agriculture at free trade.  相似文献

This article identifies an integrated teaching strategy that was originally developed for engineers, the so-called ‘micro-insertion’ approach, as a practical and effective means to teach ethics at business schools. It is argued that instructors can incorporate not only generic or thematic learning objectives for students into this method (i.e., the intended content of what is being taught: in our case, an underlying ethical base for doing business), but also do so via a strategically integrated approach regarding the appropriate mix and timing of these micro-insertions. With this in mind, we propose a qualitative and example-based approach that endeavors to provide a versatile way for business teachers to incorporate ethics into their general business classes. We also present a conceptual and theoretical framework that underpins this method, and we further provide a set of specific examples and a practical table that show how business instructors might integrate ethics-oriented micro-insertions into their teaching.  相似文献

This paper investigates empirically the effect of land invasions on farm production decisions. The main hypothesis is that more invasions in a region are associated with lower investment, and in particular a bias towards annual crops as opposed to long‐term crops. We use a county‐level dataset for the state of Paraná, Brazil, from 2003 to 2007, with 1,995 observations. The panel data structure allows us to control for fixed effects, such as the formalisation of land titles and land concentration, which might be correlated with the intensity of invasions. An instrumental variable fixed effects model was estimated to avoid other sources of bias. Our main finding is that land invasions are associated with lower long‐term crop production and a higher percentage of annual crops, which could accelerate land degradation, and undermine environmental sustainability.  相似文献
