We investigate the performance and risk of Socially Responsible Investment (SRI) equity funds in the Australian market and find no significant difference between the returns of SRI and conventional funds. In an extension to prior literature, we examine the impact of the number of positive, negative and total screens funds impose on performance and risk. We find little evidence of positive or negative screening impacting total return, but find weak evidence that funds with more screens overall provide better risk-adjusted performance. Positive screening significantly reduces funds’ risk. However, negative screening significantly increases risk and reduces funds’ abilities to form diversified portfolios.  相似文献

This study examines the antecedents and consequences of both timing and content of idiosyncratic deals (i-deals) for attracting and retaining valuable employees. A resource exchange frame theorizes the influence pattern of personal individualism value, social skill, and perceived insider status on i-deals timing. Individualism and social skill are expected to relate to both ex ante and ex post i-deals; perceived insider status is anticipated to relate only to ex post i-deals. The frame also suggests that i-deals’ content and personal development relate primarily to relational and balanced psychological contracts; the other ex post i-deals, flexibility and workload reduction relate to transactional psychological contracts. The frame was tested with data collected from 289 Chinese employees in the telecommunication industry.  相似文献

Using a unique dataset of corporate bond trading information and corporate governance evaluation scores, this study examines the determinants of corporate bond market liquidity in Korea. In particular, this study explores whether corporate governance performance of a company influences liquidity of bonds issued by the company. The paper reports three important findings. First, the issue size and age of bond are important determinants of bond liquidity. Second, liquidity of corporate bonds is influenced by changes in macroeconomic conditions. Third, and most importantly, better corporate governance increases liquidity of corporate bonds. This result suggests that corporate governance is an important determinant of bond liquidity, as it lowers transaction costs by improving transparency and reducing asymmetry of information. This paper contributes to the literature by providing new evidence that corporate governance performance is an important determinant of liquidity in corporate bond markets.  相似文献

Recently, many luxury brands have begun to launch limited edition (LE) products. When this happens, advertisers implement two typical types of scarcity messages for LE products: limited‐time scarcity (LTS) versus limited‐quantity scarcity (LQS) messages (Cialdini, 2008). Prior research offered empirical evidence that these scarcity messages make consumers feel that LE products are more special, unique, and valuable, and thus, positively influence their evaluation of the product (Aggarwal, Jun, & Huh, 2011). The current study examined the differential effects of LTS and LQS messages on different types of LE products by focusing on consumers’ need for uniqueness.  相似文献

We document that contrary to the conventional view, the costs of domestic firms in terms of selling, general and administrative expenses and cost of goods sold increase significantly following exogenous shocks that increase competition, namely material import tariff cuts affecting US manufacturing industries over the period 1974–2005. Incompatible with an agency explanation, the cost increase is more pronounced among firms with higher CEO/insider/board ownership. We further find that the cost increase is more evident among firms with smaller market share and among focused firms. Generally, our results are consistent with the notion of ‘dissipative competition’ discussed in the seminal papers by Tullock.  相似文献
