Risk Awareness of Interpersonal Trust and Entrepreneurship in China: Evidence from Survey Data

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.     

Value relevance of proportionate consolidation versus the equity method: Evidence from Hong Kong

Whether proportionate consolidation (PC) or the equity method (EM) provides more informative financial statements is a controversial issue. This study uses data from listed companies in Hong Kong to investigate the value relevance of the EM compared with PC during 2005–2008 when the local word-for-word equivalent HKAS 31 offered the same options. The results of this study provide evidence that PC does not offer higher value relevance than the EM. PC’s horizontal aggregation of a portion of the operations, assets and liabilities of the jointly controlled entities with those of the venturer is less informative to investors than the EM’s vertical aggregation.

Behavioral theories and the pricing of IPOs’ discretionary current accruals

The main purpose of this paper is to provide additional evidence about the effect of discretionary current accruals on the pricing of IPOs. This paper seeks to discriminate between two alternative explanations for the prior findings: (1) behavioral biases coupled with limited arbitrage; and (2) the sample- and period-specific nature of the results in the prior literature. The IPOs from 1962 to 1998 were used to obtain the following results. First, there was not a negative association observed between discretionary current accruals and subsequent price performance for the 1926–1971 period. Second, analysis reveals that the pattern of cross-sectional evidence is inconsistent with the predictions made by behavioral theories. Third, in the 1972–1998 period, evidence of predictable negative performance attributable to IPO discretionary current accruals is limited to NASDAQ firms. These findings are difficult to reconcile with the explanation of behavioral biases coupled with limited arbitrage.     

Intelligent agents for adaptive security market surveillance

Market surveillance systems have increasingly gained in usage for monitoring trading activities in stock markets to maintain market integrity. Existing systems primarily focus on the numerical analysis of market activity data and generally ignore textual information. To fulfil the requirements of information-based surveillance, a multi-agent-based architecture that uses agent intercommunication and incremental learning mechanisms is proposed to provide a flexible and adaptive inspection process. A prototype system is implemented using the techniques of text mining and rule-based reasoning, among others. Based on experiments in the scalping surveillance scenario, the system can identify target information evidence up to 87.50% of the time and automatically identify 70.59% of cases depending on the constraints on the available information sources. The results of this study indicate that the proposed information surveillance system is effective. This study thus contributes to the market surveillance literature and has significant practical implications.

Optimal and robust designs for trigonometric regression models

This article presents discussions on the optimal and robust designs for trigonometric regression models under different optimality criteria. First, we investigate the classical Q-optimal designs for estimating the response function in a full trigonometric regression model with a given order. The equivalencies of Q-, A-, and G-optimal designs for trigonometric regression in general are also articulated. Second, we study minimax designs and their implementation in the case of trigonometric approximation under Q-, A-, and D-optimality. Then, We indicate the existence of the symmetric designs that are D-optimal minimax designs for general trigonometric regression models, and prove the existence of the symmetric designs that are Q- or A-optimal minimax designs for two particular trigonometric regression models under certain conditions.     

美国反残疾人就业歧视法律制度及其借鉴研究

美国有着完备的反残疾人就业歧视的法律体系,包括宪法、基本法律及专门法律三个层次。通过颁布《康复法》及《美国残疾人法》,确立了反残疾人就业歧视的基本法律制度,并设有独立的平等就业机会委员会作为反残疾人就业歧视的联邦执法机构,通过接受投诉、展开调查、进行调解、提起诉讼及执行等程序来保障其权力的行使,有效地维护了残疾人就业的基本权利。美国的反残疾人就业歧视基本法律制度及其执法程序保障对我国完善反残疾人就业歧视制度有重要的借鉴意义。
