Corporate Sustainability and Economic Performance: an Empirical Analysis of a Voluntary Environmental Program in the USA

Voluntary environmental programs (VEPs) are designed based on a win–win approach to environmental protection that reconciles environmental protection and economic performance. Despite the claims about VEPs, there has been an ongoing debate over their efficacy with regard to whether environmental goals are balanced by economic interests on both theoretical and empirical grounds. To resolve this controversy, this paper empirically investigates a public VEP by the US Environmental Protection Agency: Green Lights (GL). For this, the paper constructs a treatment effects regression model to account for the effects of non‐random assignment for GL participants and non‐participants. The proposed model can simultaneously estimate probit models that predict corporate participation in the GL program and linear models that test the extent to which this participation contributes to economic performance. The results indicate significant positive effects of corporate participation in the GL program on economic performance, providing support for the win–win perspective.

Equity market liberalization and corporate governance

Equity market liberalizations open up domestic stock markets to foreign investors. A puzzle in the literature is why developing countries exhibit relatively small financial impacts associated with liberalizations. We use cross-firm variation in corporate governance at the time of the official liberalization of the equity market in Korea to test whether governance can explain the extent to which firms benefit when countries liberalize. The results show that better-governed firms experience significantly greater stock price increases upon equity market liberalization. Following the liberalization in Korea, foreign ownership in firms with strong corporate governance was significantly higher than that in firms with weak governance. Better-governed firms also exhibit higher rates of physical capital accumulation after liberalization.     

Tests of the efficiency of the U.S. rights offering market: An option pricing approach

The efficiency of the U.S. market for stock purchase rights is empirically analyzed in an options framework, in which prices of rights, given the prices of underlying stock, are examined with regard to the possibilities of actually earning above-normal profits, considering the risk taken. Two neutral hedging tests for market efficiency, along with a simple buy-and-exercise trading strategy, are applied to daily traded rights data. Results from ex-post hedging tests suggest that the trading strategy based on the rights valuation model is able to differentiate between overpriced and underpriced rights so as to generate substantial book profits. The positive ex-ante hedge return, found to exist empirically, is completely eliminated once transaction costs are introduced, lending support for the efficient U.S. rights offering market on an after-transaction cost basis.     

Underwriter warrants,underwriter reputation,and growth signaling

We present an alternative explanation of warrant use for underwriter compensation. We consider underwriter warrants as a signaling device to convey an issuing firm’s future growth potential and test this signaling role of warrant use by taking a direct approach in a seasoned equity offering (SEO) environment. Employing a matched-sample approach, we find that the use of warrants mitigates the negative price effects of SEOs. Specifically, the issuance of SEOs with warrant-based compensation has a significantly less negative impact on abnormal return performance than the issuance of SEOs with cash-based compensation. The results of logit regressions confirm this linkage. We further find that this less negative impact on firm value is attributable to the signaling value representing the issuing firm’s future growth prospects through warrant compensation even in the presence of underwriter reputation variables. These results suggest that firms with greater growth prospects benefit more by issuing SEOs with warrant compensation than with cash compensation. Overall, our results support the growth signaling effect of warrant compensation as an additional role of underwriter warrants in the SEO market.

The Impact of Information Release on Stock Price Volatility and Trading Volume: The Rights Offering Case

This paper examines whether information released via rights offering announcements induces changes in price volatility and trading volume of underlying stock. The results of this paper provide support for the release of new information via offering announcements and evidence of its effects on price volatility and volume of underlying stock. Specifically, utilization of the announced information by investors is evidenced by greater trading volume following the announcement date than during the pre-announcement period. We interpret this result to mean that informedness dominates consensus. However, stock price volatility decreased from the pre-announcement period to the post-expiration period of rights offerings.     

Earnings growth and the bull market of the 1990s: Is there a case for rational exuberance?

This paper examines whether permanent earnings growth, crucial to stock valuation, increased during the 1990s, as suggested by proponents of the new economy. Using S&P 500 earnings for the period of 1951–2000, we do not find strong evidence of either a one-time structural break or gradual change. However, the confidence interval on permanent earnings growth is wide enough to include an increase that is roughly consistent with the bull market of the late 1990s. Thus, we cannot reject a rational basis for that exuberance.     

Investigating effects of organisational culture and learning on environmental collaboration and performance of Korean exporting firms

This paper presents an empirical study of the effect of organisational culture and learning capability factors on environmental collaboration and performance in green supply chains. A conceptual model and variables were derived from organisational culture, learning, and collaboration theory and tested with Korean exporting firms. Learning capability was found to positively affect environmental collaboration as staff behaviour, attitudes and learning about environmental practices in a focal firm can be increased from suppliers and customers and then disseminated internally. Further, environmental collaboration was found to positively affect environmental performance due to a focal firm sharing these learned capabilities about the environment with other supply chain partners. However, organisational culture was not found to positively affect environmental collaboration. The findings suggest firms can improve environmental capabilities and performance through shared learning with supply chain partners and ensuring they are internally disseminated in the focal organisation.     

Globalization and transformation of human resource management in South Korea

Developments in the area of globalization, labour markets and human resource management (HRM) are topical and have high profiles. Yet they are often underpinned by several older and implicit views. This paper examines five propositions in this respect. We discuss globalization, often taken as driving such developments, and the role of supportive and limiting factors to its influence. We use the case of South Korea, as the main direction of change here is seen as from 'traditional' employment security and seniority-based systems of employee resourcing and rewarding, towards 'newer' flexible and performance-based ones. This seems, on the surface, a case of practice transfer in a somewhat inhospitable climate. We examine and evaluate the restraints, direction and extent of such changes, and arguments that HRM systems are being transformed by such developments. We find that the situation is more constrained and ambiguous.
