What kind of assumptions need to be realistic and how to test them: A response to Tsang (2006)

Tsang (2006) contends that certain core assumptions of a theory, which are typically about people's behaviors or thoughts, need be realistic, because they determine the viability of the mechanism that generates a hypothesized relationship. While Tsang's (2006) article rightly emphasizes the importance of realistic assumptions, it neglects the issue that certain kinds of assumptions are necessarily unrealistic for the roles that they play in theory development and testing. Therefore, researchers should not be criticized for making unrealistic assumptions of the latter kinds. Furthermore, by deliberating on the assumptions underpinning a theory, researchers can construct theories with better explanatory power and further develop existing theories. Tsang (2006) also suggests two approaches for testing assumptions, namely, a structural model and direct inquiry approaches. Although these approaches have certain merits, they also have limitations that may render the evidence gathered unreliable under certain situations. Two alternative approaches, namely, the experimental‐causal‐chain and the moderator‐of‐process designs, address these limitations. The researcher could consider adopting these designs as well in order to improve the rigor of assumption testing. Copyright © 2010 John Wiley & Sons, Ltd.     

Staff localization and environmental uncertainty on firm performance in China

This paper examined the form of the localization–performance relationship as moderated by environmental uncertainty. We postulated that the positive impact of staff localization on firm performance only continues to a certain point. Beyond this point, the costs of a high degree of staff localization outweigh the benefits. The negative effect of an increase in localization beyond an optimal point is expected to be stronger under the condition of high environmental uncertainty. Both the curvilinear relationship and the moderating effect of environmental uncertainty are confirmed through the survey results of 111 MNC subsidiaries operating in China. The result suggests that MNCs should pay particular attention to balance their deployment of local staff and expatriates in their international expansion.     

A Multilevel Investigation of the Role of Retail Stores in Cross-Border Shopping

This study postulates that individual retail stores play a central role in attracting tourists to engage in cross-border shopping, and it examines both individual-level and store-level effects on cross-border shopping motives and behaviors. It proposes a framework of relationships leading from cross-border shopping motives to store outcomes and destination outcomes through the mediating roles of store loyalty program benefits and store shopping satisfaction. This study further examines the cross-level direct and moderating effects of store brand image. By using a multilevel design, this study seeks to better identify the role of retail stores in tourism shopping.     

Do Investors Value a Firm’s Commitment to Social Activities?

Previous empirical research has found mixed results for the impact of corporate social responsibility (CSR) investments on corporate financial performance (CFP). This paper contributes to the literature by exploring in a two stage investor decision-making model the relationship between a firm’s innovation effort, CSR, and financial performance. We simultaneously examine the impact of CSR on both accounting-based (financial health) and market-based (Tobin’s Q) financial performance measures. From a sample of top corporate citizens, we find that: (1) a firm’s social responsibility commitment (CSR) contributes to its financial performance; (2) after controlling for investment in innovation activities, CSR continues to have a positive impact on a firm’s financial performance; (3) the customer dimension of CSR has a positive effect on both CFP measures, whereas the employee dimension indicates a significant impact only on financial heath; and (4) the community relation dimension of CSR only affects the market-based CFP measure of firms with high innovation intensity.     

Dominance in Hong Kong's Gas Industry

Although Hong Kong is widely regarded as a free andcompetitive economy, there are actually no competitionlaws or comprehensive competition policies in HongKong. The government argues that a sector-specificapproach to safeguard competition is more practicable.In this paper, a sector-specific approach is adoptedto analyze the problem of dominance in Hong Kong's gasindustry. Instead of imposing extensive governmentregulations on the dominant firm in the industry, theauthor argues that a better way to discipline the firmis by introducing natural gas and a common carriersystem to Hong Kong.     

Rating tourism and hospitality journals

This paper reports on the findings of a global study of tourism and hospitality academics asking them to rate their collective literature. The study adopted a peer assessment method, using a snowball sample to maximize response rates. Overall, 70 tourism and hospitality journals were assessed (40 tourism and 30 hospitality) by 314 tourism and 191 hospitality experts. The study revealed that tourism and hospitality community, collectively, rates its journals in a clear hierarchy based on a combination of awareness and perceived quality rating.     

Effects of Economic Shocks on Children's Employment and Schooling in Brazil

This paper uses longitudinal employment survey data to analyze the impact of household economic shocks on the schooling and employment transitions of young people in metropolitan Brazil. The paper uses data on over 100,000 children ages 10-16 from Brazil's Monthly Employment Survey (PME) from 1982 to 1999. Taking advantage of the rotating panels in the PME, we compare households in which the male household head becomes unemployed during a four-month period with households in which the head is continuously employed. Probit regressions indicate that an unemployment shock significantly increases the probability that a child enters the labor force, drops out of school, and fails to advance in school. The effects can be large, implying increases of as much as 50% in the probability of entering employment for 16-year-old girls. In contrast, shocks occurring after the school year do not have significant effects, suggesting that these results are not due to unobserved characteristics of households that experience unemployment shocks. The results suggest that some households are not able to absorb short-run economic shocks, with negative consequences for children.     

Specialization, Transaction Efficiency, and Firm Size: Empirical Evidence

The paper provides some empirical evidence for the relationship between average firm size and the relative transaction efficiency and per capita income as hypothesized by Liu and Yang in Journal of Economic Behavior and Organization 42(2) (2000):145–65. The empirical data of 11 industries in Hong Kong from 1982 to 1999 are found to be broadly consistent with the predictions of Liu and Yang.     

Schooling as a Lottery: Racial Differences in School Advancement in Urban South Africa

This paper analyzes the large racial differences in progress through secondary school in South Africa. Using recently collected longitudinal data we find that grade advancement is strongly associated with scores on a baseline literacy and numeracy test. In grades 8-11 the effect of these scores on grade progression is much stronger for white and coloured students than for African students, while there is no racial difference in the impact of the scores on passing the nationally standardized grade 12 matriculation exam. We develop a stochastic model of grade repetition that generates predictions consistent with these results. The model predicts that a larger stochastic component in the link between learning and measured performance will generate higher enrollment, higher failure rates, and a weaker link between ability and grade progression. The results suggest that grade progression in African schools is poorly linked to actual ability and learning. The results point to the importance of considering the stochastic component of grade repetition in analyzing school systems with high failure rates.
