Oil shocks,policy uncertainty and stock returns in China

This paper examines the interdependence of China's policy uncertainty, the global oil market and stock market returns in China. A structural VAR model is estimated that shows that a positive shock to economic policy uncertainty in China has a delayed negative effect on global oil production, real oil prices and real stock market returns. Shocks to oil market‐specific demand significantly raise China's economic policy uncertainty and reduce the real stock market returns. As measured by a spillover index, the interdependence between these variables has been rising since 2003 as China's influence in the oil market has increased. An equivalent spillover index calculated for the US is smaller and has been largely flat over time.     

Revisiting the Concept of a Societal Orientation: Conceptualization and Delineation

Marketers have traditionally evaluated products and practices on the basis of whether something could be sold. It is also important to evaluate products and practices from a societal perspective, “Should a product be sold?” The first idea reflects a managerial orientation and what must be done to sell a product; the second idea reflects a societal orientation and the impact of selling a product. In relation to the second idea, the societal marketing concept was introduced in 1972. There has been little advancement in our understanding of a societal orientation since that time. The current study presents a conceptualization of a societal orientation based on a review of literature and qualitative interviews. The construct was conceptualized as “attention to the long-term well-being of individuals and society at large by enhancing positive impacts from and reducing negative effects associated with production and consumption of a product.” Five domains comprising a societal orientation are proposed: physical consequences, psychological well-being, social relationships, economic contribution, and environmental consciousness.

Estimation of Binary Response Models With Endogenous Regressors

This paper reviews six approaches to binary response (y₁) structural forms with an endogenous regressor y₂: (i) the two‐stage least squares estimator‐like substitution approach, (ii) the control function approach, (iii) the system reduced‐form approach, (iv) the artificial instrumental regressor approach, (v) the transformed‐response instrumental variable estimator approach and (vi) the classical maximum likelihood estimator approach. The applicability of the six methods differs greatly, depending on whether y₂ is a continuously distributed random variable or a discrete transformation of a latent . We conduct a real‐data‐based simulation study, and provide an empirical illustration. Our overall recommendation is using (i) and (ii), as the others have undesirable features such as analytic complexity in (iii), computational difficulty in (iv) and (vi), and poor finite‐sample performance in (v).     

Building Trust Between Consumers and Corporations: The Role of Consumer Perceptions of Transparency and Social Responsibility

Developing trust in a company is a significant part of building the company-consumer relationship. Previous studies have sought to identify the positive consequences of trust such as loyalty and repurchase, but the question of what builds trust remains largely unanswered. To answer the question, we developed a model that depicts the relationships among transparency, social responsibility, trust, attitude, word-of-mouth (WOM) intention, and purchase intention. An online survey was conducted with a US nationwide sample of 303 consumers, and the data were analyzed using the structural equation modeling method. The results indicated that consumers’ perceptions of a corporation’s efforts to be transparent in the production and labor conditions and to be socially responsible by giving back to the local community directly affected these consumers’ trust and attitudes toward the corporation, and indirectly affected their intentions to purchase from and spread positive WOM about the corporation. Theoretical and practical implications are discussed.     

机构投资对我国资本市场资产价格影响的实证研究

本文以1999年3月到2011年3月的沪深主板上市公司月收益率为样本,通过定义机构投资者的投资策略,对加入机构投资者影响后的CAPM扩展模型进行实证研究,发现扩展模型消除了经典CAPM中存在的异方差性,且不存在一阶自相关性;资产组合的收益率同市场组合收益率呈反比关系,与基准投资组合收益率呈正比关系;模型拟合度有了很大的改善。机构投资对我国资本市场资产价格产生了积极的影响。因此,我国资本市场应该大力发展机构投资者,机构投资者本身也应该朝着健康的方向发展。

Corporate social responsibility and stakeholder value maximization: Evidence from mergers

Using a large sample of mergers in the US, we examine whether corporate social responsibility (CSR) creates value for acquiring firms' shareholders. We find that compared with low CSR acquirers, high CSR acquirers realize higher merger announcement returns, higher announcement returns on the value-weighted portfolio of the acquirer and the target, and larger increases in post-merger long-term operating performance. They also realize positive long-term stock returns, suggesting that the market does not fully value the benefits of CSR immediately. In addition, we find that mergers by high CSR acquirers take less time to complete and are less likely to fail than mergers by low CSR acquirers. These results suggest that acquirers' social performance is an important determinant of merger performance and the probability of its completion, and they support the stakeholder value maximization view of stakeholder theory.
