Sun Yat-sen and Henry George:

A bstract . Of Sun Yat-sen's "Three Principles of the People," the third principle, namely the People's Livelihood, forms the ultimate goal for social welfare. In this principle Dr. Sun tried to syncretize the economic theories of the West and adapt them within the Chinese context.
The equalization of land ownership through taxation of self-assessed land values, and the land value increment tax are the most essential ingredients of the third principle. Underlying Dr. Sun's concept of equalization of land ownership is the unearned increment theory of Henry George.
Dr. Sun conceived of agrarian reform as basic to the solution of the livelihood problem. Henry George also saw the cause of distress and destitution in the defective land tenure structure and the monopoly of land.

All for one,one for all: Coopetition and virtual team performance

This study establishes a model based on coopetition theory to explain the formation of team performance in virtual teams. We tested the model in information technology (IT) organizations, and found applicability of coopetition in influencing team performance and knowledge sharing. Knowledge sharing is indirectly influenced by team politics and social capital (i.e., trust, social interaction and shared vision) via the mediation of cooperation and competition, while team performance is indirectly affected by team politics and social capital via the mediation of cooperation, team emotional intelligence and team competence.     

Does corporate governance play an important role in BHC performance? Evidence from the U.S.

This study explores the relationship between the operating performance and corporate governance of bank holding companies (BHCs) in the U.S. The modified data envelopment analysis (DEA) is utilized to integrate the five rating indicators of CAMEL (Capital Adequacy, Asset Quality, Management, Earnings, and Liquidity) so as to estimate the BHCs' performance. This study also employs the modified tiered DEA to categorize 68 BHCs into three Tiers. Additionally, the truncated-regression is employed to discuss whether or not the corporate governance would affect the performance of BHCs. The empirical results present the trade-off relationship with CAMEL indicators in the Tier1—Efficient BHCs. Moreover, it has been found that there are negative impacts on BHC's performance from board size, outside directors, the average age of directors and CEO/Chairman duality, while there are positive impacts from the number of committee and Big-4 auditors. The results further prove that corporate governance is important for the operating performance of BHCs.

Non-parametric method for European option bounds

There is much research whose efforts have been devoted to discovering the distributional defects in the Black–Scholes model, which are known to cause severe biases. However, with a free specification for the distribution, one can only find upper and lower bounds for option prices. In this paper, we derive a new non-parametric lower bound and provide an alternative interpretation of Ritchken’s (J Finance 40:1219–1233, 1985) upper bound to the price of the European option. In a series of numerical examples, our new lower bound is substantially tighter than previous lower bounds. This is prevalent especially for out of the money options where the previous lower bounds perform badly. Moreover, we present how our bounds can be derived from histograms which are completely non-parametric in an empirical study. We discover violations in our lower bound and show that those violations present arbitrage profits. In particular, our empirical results show that out of the money calls are substantially overpriced (violate the lower bound).     

家族控制、金融发展与上市公司现金股利政策

本文以中国A股上市公司为样本,考察家族控制、金融发展对于上市公司现金股利政策的影响。实证发现,家族上市公司的派现意愿和派现水平显著低于非家族上市公司,一个重要原因在于家族上市公司面临着比非家族上市公司更高的融资约束。进一步地,在良好的外部金融环境中,上市公司的派现意愿和派现水平显著更高,而且金融发展有助于缓解家族上市公司的融资约束问题并推动其现金股利的发放。     

车险已发生已报告未决赔款准备金研究——基于报案自动立案的方法

在目前管理模式下,已发生已报告未决赔款准备金存在计提不及时、不真实的问题。本文采用理论和实证相结合的研究方法,从流程再造的角度,提出采用报案自动立案、核损和理算后分别自动调整已发生已报告未决赔款准备金的方法,并进行实证检验和成本收益分析。结果表明,增加这一管理环节有利于提高已发生已报告未决赔款准备金提取的及时性和准确性。
