Effects of litigation under the Endangered Species Act on forest firm values

The Endangered Species Act (ESA) has been a source of litigation and subject to court interpretation during the past several decades. In this study, event analysis was employed to examine the impact of six court decisions related to the ESA on the financial performance of U.S. forest products firms. The finding of abnormal returns revealed that all six events generated the expected positive or negative returns, and among them, four were statistically significant. Changes in systematic risk reflected the reaction of the stock market to the verdict announcements. Programs designed for habitat conservation can be implemented to compensate private landowners or firms for costs associated with protecting species on private forestlands.

Sustainability Strategy and Eco‐Innovation: A Moderation Model

This study develops a moderation model to examine the role of a proactive environmental strategy on eco‐innovation. Drawing upon the perspectives of contingency theory, this study argues that the impacts of sustainability strategy on eco‐innovation depend on market demand, innovation intensity and government subsidy. The sample used to test the hypotheses is obtained from the Community Innovation Survey in Taiwan. A total of 2955 manufacturing firms are included in the final sample. A logit moderating regression is adopted to analyze the models. The results reveal that market demand and government subsidy positively moderate the relationship between environmental strategy and eco‐innovation. Specifically, firms are more likely to adopt a proactive environmental strategy to improve eco‐innovation under high levels of market demand and government subsidy. Furthermore, the results indicate that innovation intensity affects the effect of environmental strategy on eco‐innovation, but the direction of the influence varies with different categories of eco‐innovation.

Information uncertainty,information asymmetry and corporate bond yield spreads

This study examines the effects of information uncertainty and information asymmetry on corporate bond yield spreads using American data from 2001 to 2006. Empirical results of this study show that investors charge a significant risk premium for both information uncertainty and information asymmetry when controlling for variables well known in the literature. The results are robust even when controlling for credit ratings. Finally, information uncertainty and asymmetry help structural-form credit models explain the yield spreads of bonds with short maturities.
