Estimating the commuting cost and commuting time property price gradients

In this paper, we estimate the property price gradients in Hong Kong. We distinguish our effort from previous studies on the subject by directly measuring the economic distance, i.e., the monetary commuting cost and commuting time, instead of merely the physical distance. Our results are generally supportive of the prediction of a negative property price gradient. In one specification, the estimated capitalization of the savings of commuting cost in property prices appears to be just right. The expected negative effect of commuting time on property values, however, can only be detected among observations with larger commuting times. Nevertheless, over the range where the effect of commuting time has the expected negative sign, the values of time implied by the estimates agree well with the results reported in the transportation economics literature. © 2003 Elsevier B.V.

Education and competitive economy: How do cultural dimensions fit in?

Globalization has changed the way people behave in different aspects of life. One of the significant differences is that people are now competing with everyone around the world, not just people within or near their own regions. A good way of remaining competitive is to provide quality education that can help students meet the needs of the competitive economy. However, not all nations are responding in the same way. Using a quantitative approach, this explorative study seeks to discover if, and how, cultural dimensions fit into the process of meeting the demands of the competitive economy by means of education across regions. Forty-three regions with different ratings on the Power Distance Index (PDI), Individualism (IDV), Masculinity (MAS), and the Uncertainty Avoidance Index (UAI) are included in this study. The results show that UAI, PDI and IDV are significant factors relating to this issue. © Springer Science+Business Media B.V. 2009.published_or_final_versionSpringer Open Choice, 01 Dec 201

Cultural Dimensions, Ethical Sensitivity, and Corporate Governance

The economic globalization process has integrated different competitive markets and pushes firms in different countries to improve their managerial and operational efficiencies. Given the recent empirical evidence for the benefits to firms and stakeholders of good corporate governance (CG) practice, it is expected that good CG practice would be a common strategy for firms in different countries to meet the increasingly intense competition; however, this is not the case. This study examines the differences in CG practices in firms across different countries using the concept of ethical sensitivity. Through the regression analysis of 271 firms in 12 countries and regions, it is found that Hofstede's cultural dimensions can explain the differences in CG practices. Furthermore, the results demonstrate the influence of culture on ethical sensitivity, which eventually determines the CG practices in different regions. © 2011 The Author(s).published_or_final_versionSpringer Open Choice, 28 May 201

Selection in spatial working memory is independent of perceptual selective attention, but they interact in a shared spatial priority map

We examined the relationship between the attentional selection of perceptual information and of information in working memory (WM) through four experiments, using a spatial WM-updating task. Participants remembered the locations of two objects in a matrix and worked through a sequence of updating operations, each mentally shifting one dot to a new location according to an arrow cue. Repeatedly updating the same object in two successive steps is typically faster than switching to the other object; this object switch cost reflects the shifting of attention in WM. In Experiment 1, the arrows were presented in random peripheral locations, drawing perceptual attention away from the selected object in WM. This manipulation did not eliminate the object switch cost, indicating that the mechanisms of perceptual selection do not underlie selection in WM. Experiments 2a and 2b corroborated the independence of selection observed in Experiment 1, but showed a benefit to reaction times when the placement of the arrow cue was aligned with the locations of relevant objects in WM. Experiment 2c showed that the same benefit also occurs when participants are not able to mark an updating location through eye fixations. Together, these data can be accounted for by a framework in which perceptual selection and selection in WM are separate mechanisms that interact through a shared spatial priority map
