Corporate giving in Taiwan: agency cost theory vs. value enhancement theory

This article examines the determinants of corporate giving (CG) in Taiwan according to agency cost (AC) and value enhancement (VE) theories. Panel regression test results reveal several new and interesting pieces of evidence. First, VE determinants outweigh AC determinants in explaining CG there. Second, the positive link between the current CG ratio (CGR) and the lagged CGR (CGR(-1)) suggests the consistent nature of CG. Third, after the global financial crisis in 2008, the influence of debt leverage on CGR vanished, but the impact of managerial insiders’ shareholdings on CGR became significant. Last, the influences of VE determinants and CGR(-1) on CGR remain during both pre-crisis and post-crisis periods. Moreover, after the crisis, CG was still motivated to create current value for shareholders, and was apparently used as a business strategy to signal companies’ financial or managerial stability.

减排与增长:服务业如何实现绿色均衡发展?

服务业是中国经济转型和产业结构升级的重要抓手,在资源与环境"双重"约束日益趋紧的背景下,有必要研究服务业绿色发展问题。能否在减排成本最小的前提下提高服务业增长率,走出一条绿色发展路径?为此,文章创新性地将排放权交易市场引入服务业部门,采用方向性距离函数、非线性规划等实证研究方法测算2004-2012年中国服务业14个细分行业的绿色效率和碳排放影子价格。研究表明:中国服务业发展方式并非"绿色",服务业减排成本和碳排放量逐年增长,减排面临巨大的经济压力;在文章设计的排放权交易模型下,服务业细分行业能够形成一个统一的影子价格,从而实现一条绿色发展路径,该路径满足帕累托有效和投入产出技术有效;在均衡路径上,流通服务业应出售排放权,而其他减排成本较高的服务业购买排放权。     

The dynamic role of small- and medium-sized multinationals in global production networks: Norwegian maritime firms in the Greater Shanghai Region in China

This article examines the role of small- and medium-sized multinational enterprises (MNEs) in the dynamic development of global production networks (GPNs) in the maritime industry. It studies the dynamism between subsidiaries of Norwegian maritime firms and regional actors and institutions in the Greater Shanghai Region of China from the perspectives of the subsidiaries. It argues that strategic coupling, recoupling and decoupling are partly the results of regional selection mechanisms. However, in the cases where the subsidiaries are embedded within the host region, the strategies and behaviour of MNEs are of decisive importance for the dynamic development of GPNs.     

积极应对入世后的挑战

<正> 中国如今已成功入世。在刚刚结束的九届全国人大五次会议上,以江泽民为首的党中央号召全国人民要乘中国入世的东风,将我国的改革开放推向一个新的阶段。我国各行各业将在经济全球化浪潮的搏击中不断壮大,所有这一切都需要我们一步一步地脚踏实地地努力拼搏。世贸组织规则是一部内容十分广泛而复杂的国际贸易法体系,如何去熟悉和掌握世贸组织的贸易规则并为我所用,是摆在我们面前一项长期而艰巨的任务。应对入世后的挑战有许许多多的工作要我们去做,以下是我们要做的较为迫切的几件工作:     

The joint effects of social identity and institutional pressures on audit quality: The case of the Chinese Audit Industry

This article examines how social identity links institutional pressures and audit quality. Combining institutional theory and social identity theory, we theoretically argue that the interaction between social and institutional forces shapes audit quality. Through an analysis of Chinese audit firms from 2000 to 2007, we show that isomorphic imitation has a more significant effect on firms belonging to the same-identity group than firms across cross-identity groups; foreign-affiliated audit firms are more willing to conform to normative pressure from professional networks than local firms; and foreign-affiliated firms are coerced to adapt to the local government’s expectation, particularly when they have a geographically concentrated customer base. We further reveal that a larger customer base attenuates within-identity group imitation but strengthens cross-identity group imitation. The results shed light on the role of social identity in shaping conformity in the audit industry, thus contributing to international convergence–divergence literature and institutional theory.

VIX term structure and VIX futures pricing with realized volatility

Using an extended LHARG model proposed by Majewski et al. (2015, J Econ, 187, 521–531), we derive the closed-form pricing formulas for both the Chicago Board Options Exchange VIX term structure and VIX futures with different maturities. Our empirical results suggest that the quarterly and yearly components of lagged realized volatility should be added into the model to capture the long-term volatility dynamics. By using the realized volatility based on high-frequency data, the proposed model provides superior pricing performance compared with the classic Heston–Nandi GARCH model under a variance-dependent pricing kernel, both in-sample and out-of-sample. The improvement is more pronounced during high volatility periods.     

Proportionally adjusted marginal pricing method to share joint costs

We consider the cost sharing problem with divisible demands of heterogeneous goods. We propose a cost sharing method called Proportionally Adjusted Marginal Pricing (PAMP) method. PAMP is a nonadditive (in the cost function) extension of average cost pricing. We introduce an axiom called Local Independence (LI) and use LI together with Continuity, Proportionality, and Scale Invariance to characterize PAMP.
