双边市场视角下的中国特大型城市展览馆定价行为和机制研究

展览市场具有双边市场的性质：以展览馆作为平台企业,连接参展商和参观者两类市场顾客,来进行交易性的或展示性的活动。本文在双边市场理论模型的基础上,结合满足中国展览业国情,尤其是特大型城市展览馆的运营特征,从非对称条件的角度构建了3种展览馆定价机制模型：（1）参展商可以识别不同类型观众;（2）参展商不可以识别各种类型的观众;（3）展览馆对不同类型观众进行参观时段限制。通过三种模型的推理与演算,我们对特大型城市展览馆的定价行为和机制进行了定量研究,在得出最优解的同时我们还结合实际对模型的结构进行了深入分析,使得本论文不仅在理论和研究方法上有所突破,更具有实践上的指导意义。

Worker Productivity, Working Time Reduction, And The Short–Run And Long–Run Employment Effects

This paper illustrates a shirking–type efficiency wage model to explain why shorter working hours cause an ambiguous effect on employment as the empirical result. We find that shorter working hours have an uncertain impact on the work effort, and the relationship between work effort and shorter working time is a decisive factor in the employment effect of working time reduction. Moreover, it is also found that, given the zero profit constraint, the long–run employment effect of reducing working hours will intensify the short–run employment effect.

Maximum likelihood estimation of seemingly unrelated stochastic frontier regressions

This paper explores the changes in value added (VA) of a sample of schools for cohorts of students finishing secondary education between 2005 and 2008. VA estimates are based on distance measures obtained from DEA models. These measures are computed for each pupil in each school, and evaluate the distance between the school frontier in a given year and a pooled frontier comprising all schools analysed. The school VA is then computed by aggregating the VA scores for the cohort of pupils attending that school in a given year. The ratio between VA estimates for two consecutive cohorts, that attended the school in different years, is taken as the index of VA change. However, the evolution of school performance over time should consider not only the movements of the school frontier, but should also take into account other effects, such as the proximity of the students to the best-practices, represented by the school frontier, observed over time. For that purpose we developed an enhanced Malmquist index to evaluate the evolution of school performance over time. One of the components of the Malmquist index proposed measures VA change, and the other measures the ability of all school students to move closer to their own school best practices over time. The approach developed is applied to a sample of Portuguese secondary schools.

Technological diversification, complementary assets, and performance

Most research on technological diversification or complementary assets has been carried out in isolation when assessing their effects on performance. In this study, we posit that technological diversification and performance are positively linked and that specialized complementary assets have a moderating effect on this relationship. This study also finds that different specialized complementary assets have distinctive moderating effects on the relationship between technological diversification and performance. We conclude that maintaining a coherent relationship between technological diversification and specialized complementary assets give firms generates competitive advantage.     

The role of domestic demand in the economic growth of Malaysia: a cointegration analysis

For the past four decades (1961-2000), the Malaysian economy grew at an impressive average rate of 6.8% per annum. The rapid growth has been attributed, in part, to the tremendous success in the export-oriented industrialization policy. Several empirical studies on export-led growth for Malaysia have, however, led to inconclusive and mixed results. This may be due to the exclusion of domestic demand in the bivariate or multivariate models used in the studies. This study re-examines the role of domestic demand in economic growth in Malaysia. Using a three-variable cointegration analysis, the study shows that there exist short run bilateral causalities among the three variables, which implies that both the export-led growth and domestic demand-generated growth hypotheses are at least valid in the short run. On the other hand, the results are not supportive of the export-led growth hypothesis in the long run. Instead, the highly significant positive impact of domestic expenditure on economic growth implies that use of domestic demand as the catalyst for growth is appropriate.     

Does a stricter enforcement policy protect the environment? A political economy perspective

The conventional wisdom suggests that a stricter enforcement policy can reduce pollution emissions. Nevertheless, this present paper argues that this assertion does not necessarily hold if the stringency of environmental regulation is subject to the influence of lobbying. A stricter enforcement policy increases the polluters’ expected financial burden, and induces them to exert greater political pressure on reducing the stringency of environmental regulation, thereby resulting in a larger amount of pollution emissions. We also show that tightening the enforcement policy can reduce efficiency. We highlight the possibility of policymaking being misguided due to overlooking the political effect of enforcement policy.
