Do environmental regulations hamper small enterprises' market entry? Evidence from China

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.

中国文化下的绩效和认可

绩效和认可的理念在中国越来越被接受,并且很多企业开始在管理实践中用认可来激励和管理员工。有关绩效与认可的理念是先进和令员工振奋的,但在中国企业实施时,常常会产生"南橘北枳"的无奈。本文探讨了在中国的环境中,和合文化、"圈子"文化、中庸文化、面子文化、"集体本位"文化对于绩效和认可的影响,并且提出了对企业的建议。     

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.     

收益率差异视角下股票流动性与资本结构关系的再检验

本文在股票收益率差异视角下，选择2000年1月到2015年12月期间中国沪、深市场307家上市公司数据，采用单方程估计法和联立方程组系统估计法研究我国上市公司股票流动性与资本结构的相互影响；并分别从股权分置改革、股权再融资、牛熊市行情三个方面对二者关系的变化与差异进行深入分析。结果表明：股票流动性与资本结构之间存在显著的负向关系，并且随着股票收益率水平的提高，负向影响越来越明显；股权分置改革后、满足再融资资格的上市公司以及牛市行情下两者的相互影响更显著。     

Environmental Kuznets Curve: Conclusive Econometric Evidence for CO2

This paper begins with a statistical formulation of the Environmental Kuznets Curve (EKC) and discusses the major econometric problems raised in the literature in testing this hypothesis using panel data. A simple t‐test is then presented that avoids these econometric problems. The result from applying the t‐test confirms conclusively the EKC for CO₂ as formulated.     

Emerging Market Firms' Internationalization: How Do Firms' Inward Activities Affect Their Outward Activities?

Research summary : In this study we examine how an emerging market firm's inward international activities (“inward activities”) are related to its outward international activities (“outward activities”) by focusing on the role of the firm's gain from its inward activities. On the one hand, drawing upon the organizational learning perspective, we propose that a firm's gain from inward activities may facilitate its outward activities through improving its resource fungibility. On the other hand, we draw upon the prospect theory to propose that a firm's gain from inward activities may hinder its outward activities by discouraging the firm's top managers from taking risks that are inherent in outward activities. With detailed data from a sample of manufacturing firms in China, we find empirical support for both lines of arguments . Managerial summary : Are emerging market firms with higher inward gain more likely to engage in outward internationalization activities? We argue that it depends upon how a firm uses its gain from inward activities. If the firm can improve its resource fungibility (particularly organizational resource fungibility) from its inward gain, it is more likely to engage in outward activities. If the firm cannot improve its resource fungiblity, the answer is no. Our findings suggest that for emerging market firms, internationalization is not just a path toward new markets; instead, it reflects how these firms exploit and explore what they have learned from their interactions with foreign firms at home in foreign markets. Therefore, managers must think more strategically on developing (organizational) resource fungibility from their inward activities . Copyright © 2017 John Wiley & Sons, Ltd.
