Is the Chinese stock market really inefficient?

Groenewold et al. (2004) documented that the Chinese stock market is inefficient. In this paper, we revisit the efficiency problem of the Chinese stock market using time-series model based trading rules. Our paper distinguishes itself from previous studies in several aspects. First, while previous studies concentrate on the viability of linear forecasting techniques, we evaluate the profitability of the forecasts of the self-exciting threshold autoregressive model (SETAR), and compare it with the conventional linear AR and MA trading rules. Second, the findings of market inefficiency in earlier studies mainly rest on the statistical significance of the autocorrelation or regression coefficients. In contrast, this paper directly examines the profitability of various trading rules. Third, our sample covers an extensive period of 1991–2010. Sub-sample analysis shows that positive returns mainly concentrate in the pre-SOE reform period, suggesting that China's stock market has become more efficient after the reform.     

The trade-off of servicing empowerment on employees’ service performance: examining the underlying motivation and workload mechanisms

Literature on empowerment as an internal marketing practice primarily documents positive effects on employees’ job performance, though increasing evidence suggests conflicting viewpoints. This study adopts an agency theoretical perspective to propose a workload mechanism, according to which the delegation of power from supervisors (principals) to service employees (agents) (i.e., servicing empowerment) is costly to employees and increases their perceived workload, which hampers their performance to serve customers. Using a laboratory experiment and a survey, this research reveals that the perceived workload and extant motivational mechanisms have conflicting effects on employees’ service performance. The former exerts a significant negative impact on tasks that involve conflicting principal-agent interests (e.g., handling customer complaints) but not on tasks with aligned principal-agent interests (e.g., organizational citizenship behaviors). Two control systems, performance appraisal (accurate and infrequent feedback) and principal-agent service goal congruence, mitigate the dysfunctional effect of perceived workload on employees’ service performance.     

The Structure of Trust in China and the U.S.

This article investigates the structure of trust in China and compares it with the U.S., using the 2000 and 2005 waves of the World Value Survey (WVS). We analyze two dimensions of trust – trust in people and trust in major companies. It is found that the level of trust has remained stable in China within the 5-year period. On the other hand, trust in major companies has declined dramatically in U.S. while trust in people has increased slightly. The structure of trust in companies is different from trust in people. For both countries, individuals with higher education tend to have a higher level of trust. Individuals who are divorced tend to have lower trust in people. Individuals who think that other people are fair are more likely to trust in people. Preference for competition has a positive effect on trust in major companies. On the other hand, some differences between the two countries are observed. Perception of fairness does not affect trust in major companies in China, while it has a positive effect in U.S. in year 2006. Preference for equality has a negative effect on trust in major companies in U.S. but no significant effect in China. The pattern of trust and its changes over time may reflect differences in market conditions in the two economies.     

Testing the sufficiency of the theory of planned behavior: a case of customer dissatisfaction responses in restaurants

This study tested the sufficiency of both the Theory of Planned Behavior (TPB) and the extended TPB models by adding the variable of past behavior. In addition, the present study examined the mediating role of the TPB variables on the relationships between past behavior and customers’ intentions to engage in different types of dissatisfaction responses (i.e., voice, negative word-of-mouth communication, and exit). Results of the study demonstrated the strong predictive power of the original TPB mode but the inclusion of past behavior did not significantly improve the predictability of the three dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by TPB variables. In the contexts of negative word-of-mouth communication, the effect of past behavior on intention was mediated by attitude. Meanwhile, both subjective norm and perceived behavioral control mediated the relationship between past behavior and the intention to engage in voice behavior.     

On the Equivalence of Ad Valorem Tariffs and Specific Tariffs under Duopoly*

Using a quantity conjectural variation model, this paper examines whether an ad valorem tariff and a specific tariff are equivalent under duopoly. We show that if the average per‐unit import tax is the same for the two tariffs, domestic output will be smaller while foreign output will be larger under an ad valorem tariff. We further show that for any value of a specific tariff, there is a Pareto‐superior ad valorem tariff for all values of conjectural variation except in the case of perfect competition where the two tariffs are equivalent.     

A Markov‐Switching Model Of Gnp Growth With Duration Dependence*

A Markov‐switching model of postwar quarterly real GNP growth is used to examine the duration dependence of business cycles. It extends the Hamilton model and the duration‐dependent model of Durland and McCurdy, and compares quite favorably to simpler models in out‐of‐sample forecasting. When an expansion begins, the probability of the expansion ending is 0.2, but it gradually decreases as the expansion ages. When a contraction begins, the probability of the contraction terminating is 0.07, but it increases rapidly as the contraction ages. Output growth slows over the course of an expansion. The hypothesis of the 7–10‐year cycle is not supported.     

Discrimination in hiring against immigrants and ethnic minorities: the effect of unionization

There has been a long debate concerning whether unions are exclusive or inclusive with respect to immigrants and ethnic minorities. In the exclusive view of unions, unionization is expected to increase the likelihood of employers asking questions that discriminate against immigrants and ethnic minorities and decrease the likelihood of employers asking Equal Employment Opportunity (EEO) questions related to immigrant or ethnic minority status. The contrary is expected for the inclusive view. Our analysis, using New Zealand data for job applications, provides some support for the inclusive view of unions, as the higher the unionization rate, the more likely EEO information is sought, but no relationship is found between unionization rate and discriminatory questioning. This suggests that unions are probably helpful in promoting diversity but not yet in combating discrimination against immigrants and ethnic minorities in hiring.     

Design of a rail transit line for profit maximization in a linear transportation corridor

This paper addresses the design problem of a rail transit line located in a linear urban transportation corridor. The service variables designed are a combination of rail line length, number and locations of stations, headway and fare. Two profit maximization models, which account for the effects of different transit pricing structures (flat and distance-based fare regimes), are proposed. In the proposed models, the effects of passenger demand elasticity and population density along the urban corridor are explicitly considered. The solution properties of the proposed models are explored and compared analytically, and the indifference condition for the two fare regimes in terms of the operator’s net profit is identified. A heuristic solution algorithm to solve the proposed models is presented. Numerical examples are provided to show the effects of the fare regimes, rail capital cost and urban configuration (in terms of urban population distribution and corridor length) on the design of the rail transit line and the profitability of the rail transit operations.     

Coping with Job Insecurity: The Role of Procedural Justice, Ethical Leadership and Power Distance Orientation

This study examines the relationship between procedural justice and employee job insecurity, and the boundary conditions of this relationship. Drawing upon uncertainty management theory and ethical leadership research, we hypothesized that procedural justice is negatively related to job insecurity, and that this relationship is moderated by ethical leadership. We further predicted that the moderating relationship would be more pronounced among employees with a low power distance orientation. We tested our hypotheses using a sample of 381 workers in Macau and Southern China. The results support all of our hypotheses. The implications of these results for research and practice are discussed.
