Tax Base and Crowding‐in Effects of Balanced Budget Fiscal Policy

A dynamic general equilibrium business cycle model is constructed with staggered price adjustment, monopolistic wage setting and distortionary taxation. The government purchases goods, runs an unemployment benefit system and balances its budget through a proportional tax on labour income. A temporary tax‐financed increase in government expenditures can lower the tax rate through a demand‐induced widening of the tax base. It is shown analytically that this allows private consumption to rise, under realistic conditions, despite the negative wealth effect of increased fiscal spending.     

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。     

基于知识的核心粘性成因及对策分析

核心“粘性”的存在,使基于核心能力的企业永续发展理论受到了质疑。本文从知识的角度入手,探求了核心能力的知识内涵,指出核心能力的最终来源是知识,而核心“粘性”也源于知识的粘滞性。解决对策是建立企业激励机制、信任机制达成企业知识共享和知识创新,从而突破双重粘性,推动核心能力不断的更新和动态提升。

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.     

会计计量与企业债券信用评级关系的应用分析——基于2006年新会计准则的思考

企业债券信用评级是企业发行债券的重要步骤,债券评级对会计信息具有依赖性,而会计信息的计量属性会直接影响会计信息,不合适的会计计量属性会对债券评级造成负面影响。本文结合2006年的新会计准则的相关规定和企业债券信用评级的特点,通过分析会计计量对信用评级的误导因素,认为借鉴国际先进经验,可以提高债券评级的可靠性和客观性,促进企业融资市场的公平性和公正性。     

Financial crisis and persistence: evidence from sticky expectations consumption growth model

We estimate the degree of stickiness in aggregate consumption growth for the U.S. considering the effects of the Great Recession. The behavior of stickiness estimate in the crisis is somewhat as the U-shaped pattern. Our findings imply that during the crisis consumers’ attentiveness to aggregate information has slightly increased, thereby reducing the persistence of aggregate consumption growth. However, the reduction in persistence is transitory. Since 1980, the U.S. faced five recessions and in most of them the degree of stickiness declined, albeit temporarily.     

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.
