Modeling Conditional Yield Densities

Given the increasing interest in agricultural risk, many have sought improved methods to characterize conditional crop-yield densities. While most have postulated the Beta as a flexible alternative to the Normal, others have chosen nonparametric methods. Unfortunately, yield data tends not to be sufficiently abundant to invalidate many reasonable parametric models. This is problematic because conclusions from economic analyses, which require estimated conditional yield densities, tend not to be invariant to the modeling assumption. We propose a semiparametric estimator that, because of its theoretical properties and our simulation results, enables one to empirically proceed with a higher degree of confidence.     

安徽省高技术产业技术创新效率研究

运用因子分析定权法测算安徽省高技术产业的技术创新效率,结果发现技术含量相对较高的产业其技术创新效率较低,而技术含量相对较低的产业其技术创新效率反而较高。这说明安徽高技术产业走技术创新之路仅处于起步阶段,而市场环境是影响安徽技术创新效率的重要因素。     

重庆在三大地域单元城镇化水平比较

Governance or reputation? Flexible tax enforcement and excess goodwill: Evidence from the taxpaying credit rating system in China

This study investigates the effect of flexible tax enforcement on firms’ excess goodwill using unique manually collected data on taxpaying credit rating in China from 2014 to 2021. We document that A-rated taxpayer firms have less excess goodwill; A-rated firms reduce excess goodwill by 0.005 vis-a-vis non-A-rated firms, which accounts for 100% of the mean value of excess goodwill. This finding holds after multiple robustness tests and an endogeneity analysis. Moreover, this negative effect is more pronounced in firms with low information transparency, that are non-state-owned and that are located in regions with low tax enforcement intensity. The channel test results suggest that taxpaying credit rating system as flexible tax enforcement reduces firms’ excess goodwill through a reputation-based effect and not a governance-based effect. This study reveals that the taxpaying credit rating system in China as flexible tax enforcement can bring halo effect to A rating firms, thereby limiting irrational M&As and breaking goodwill bubble.

Charting a Course on the Islamic Finance Ocean： A Survey of Islamic Insurance Literatures

The number of Muslim literates in Islamic finance and conventional finance, particularly Islamic insurance, has grown tremendously, so has the number of academic and professional articles, books, and other monographs published in Islamic insurance profession. Despite Islamic insurance uniqueness based on Islamic values and philosophies, its emancipation aimed to compete or eradicate the conventional insurance at both academic and professional levels. Those monographs that were intended to replace their conventional insurance counterpart have triggered endless debates among stakeholders on their authenticity and quality of knowledge and as well challenged their authors＇ authorities. Therefore, with content analysis, this survey verified whether the Islamic insurance literatures were capable of producing well-seasoned professionals of lslamic insurance. The results showed that the disputes over the available literatures might have contributed to the failure of having a standard curriculum for teaching Islamic insurance as a profession in academic at national and international levels. Review of the literatures and curriculum was recommended.     

Effective restaurant rating scale development and a mystery shopper evaluation approach

Dining is a major attraction for tourists visiting Taiwan. In 2008, the Taipei City Government commissioned a project to produce a list of recommended restaurants in Taipei for tourists. To facilitate the selection process, we developed a restaurant rating scale using a mystery shopper approach. This study entailed 20 questions that covered all elements of the consumers’ dining experience in a table-service restaurant setting, as well as a comprehensive mystery shopper training program to ensure consistency of quality in the evaluation process. This research involved the top 500 restaurants in Taipei. The findings revealed that our rating scale achieves internal consistency, validity and model fit. This study provided an important tool for further industrial applications and research opportunities. Further, this study proposes future research directions.     

Credit Rating and Monetary Policy Transmission to Equity Markets: Evidence from the Emerging Market

This study empirically estimates credit channel of the monetary policy and corporate stock return using daily stock return data including the sample with non-financial firms listed in Korea stock exchange (KOSPI). Empirical results support that changes in the basis rate turn out to increase equity returns in case of the firms with higher credit rating compared to the previous year. The estimation results confirm the conjecture that monetary policy has a significant impact on stock market through the channel of changes in credit rating.
