Recent accounting research indicates that capital markets price firms' greenhouse gas (GHG) emissions and that disclosed emissions levels are negatively associated with firms' market values. The departure point for this study is to investigate whether investors value firms differently based on the strategies firms use to mitigate GHG emissions. These strategies include making operational changes, which reduces emissions attributable to the firm, and purchasing offsets, which reduces emissions unattributable to the firm. Using an experiment, we hold constant a firm's financial performance, investment in emissions mitigation, and net emissions, and find evidence that nonprofessional investors perceive the firm to be more valuable when it primarily uses an operational change strategy versus an offsets strategy. However, consistent with theory, this result only occurs when the firm's prior sustainability performance is below the industry average and not when it is above the industry average. This difference in firm value is consistent with the notion that nonprofessional investors believe information about a firm's emissions management strategy is material. Supplemental exploratory analyses reveal that our results are mediated by investors' perception that an operational change strategy is more socially and environmentally responsible than an offsets strategy for below industry average firms. Implications for our findings on theory and practice are discussed.

Exchange seat prices are widely reported and followed as measures of market sentiment. This paper analyzes the information content of NYSE seat prices using: (1) annual seat prices from 1869 to 1998, and (2) the complete record of trades, bids and offers for the seat market from 1973 to 1994. Seat market volumes have predictive power regarding future stock market returns, consistent with a model where seat market activity is a proxy for unobserved factors affecting expected returns. We find abnormally large price movements in seats prior to October 1987, consistent with the hypothesis that seat prices capture market sentiment.

The methods of Michael R. Gibbons and Wayne Ferson (1985) are extended, relaxing the assumption that expected returns are linear functions of predetermined instruments. A model of conditional mean-variance spanning generalizes G. Huberman and S. Kandel (1987). The empirical results indicate that more than a single risk premium is needed to model expected stock and bond returns, but the number of common factors in the expected returns is small. However, when size-based common stock portfolios proxy for the risk factors, the authors reject the hypothesis that four of them describe the conditional expected returns of the other assets.

This paper examines the risks and returns of long‐term low‐grade bonds for the period 1977–1989. We find: (1) low‐grade bonds realized higher returns than higher‐grade bonds and lower returns than common stocks, and low‐grade bonds exhibited less volatility than higher‐grade bonds due to their call features and high coupons; (2) there is no relation between the age of low‐grade bonds and their realized returns; cyclical factors explain much of the observed relation between default rates and bond age; and (3) low‐grade bonds behave like both bonds and stocks. Despite this complexity there is no evidence that low‐grade bonds are systematically over‐ or under‐priced.

This paper examines the risks and returns of long-term low-grade bonds for the period 1977-89. The authors find (1) low-grade bonds realized higher returns than higher-grade bonds and lower returns than common stocks, and low-grade bonds exhibited less volatility than higher-grade bonds due to their call features and high coupons; (2) there is no relation between the age of low-grade bonds and their relaxed returns; cyclical factors explain much of the observed reaction between default rates and bond age; and (3) low-grade bonds behave like both bonds and stocks. Despite this complexity there is no evidence that low-grade bonds are systematically over- or under-priced.
