Knowledge that Transforms

This study investigates the extent to which information inferred by investors from initial announcements of corporate security offerings affects share prices in the capital markets. The empirical tests measure the response in the common stock prices of both firms announcing a security offering and non-announcing firms operating in the same industry. Small but significantly negative abnormal returns are shown by industry shares upon initial announcements of common stock, convertible debt, and straight debt public offerings. Such an industry response indicates that share prices incorporate an inside assessment of factors relevant to the valuation of an industry subset of firms.

This paper describes the firm's decision to borrow short-term versus long-term and shows how the introduction of interest rate swaps affects this choice. The model shows that in the absence of a swap market, interest rate uncertainty can lead firms to substitute long-term for short-term financing. However, when swaps exist, there is a tendency for firms that expect their credit quality to improve to borrow short-term and use swaps to hedge interest rate risk. The model suggests that, while the demand for fixed for floating swaps is enhanced, the demand for floating for fixed swaps is reduced by the presence of asymmetric information.

In this paper we provide empirical evidence consistent with the hypothesis that options market makers face risks in managing inventory that are unique to the options markets. In particular, we show that risks associated with the inability to rebalance an option position continuously and uncertainty about the return volatility of the underlying stock each account for a statistically and economically significant proportion of the bid-ask spreads quoted for a sample of Chicago Board Options Exchange options.

This paper introduces a new method to measure the unexpected component of dividend announcements. While measures used previously were based on various arbitrary models of dividend expectations, the authors' suggested method compares the reaction of stock and option prices to dividend announcements. Their measure is compared to commonly used model-based measures, to a Box-Jenkins time-series-based measure, and to a Value-Line Investor Survey-based measure of dividend surprises. The new measure is more highly correlated with the market's reaction to the announcements than are alternative measures of dividend surprises. The new measure is also shown to be insensitive to the extent to which the options used to identify unexpected dividend announcements are in- or out-of-the-money.

Many firms with dividend reinvestment plans also allow their shareholders to voluntarily invest supplemental funds to purchase additional shares. The purchase price for newly‐issued shares often is determined by the average stock price over a prespecified time period preceding the investment date. This gives the firm's shareholders an option to invest in additional shares only when the stock price exceeds the computed average. This paper uses both theoretical and numerical methods to analyze the value of these voluntary purchase options in theory and practice.

This paper provides a simple proof of a recent theorem presented by In the single-factor case, the theorem asserts that any variable correlated with the factor can serve as the benchmark in an approximate APT expected return relation. The significance of this result is considered and a new direction for empirical work on "arbitrage pricing" is outlined.

This paper introduces a new method to measure the unexpected component of dividend announcements. While measures used previously were based on various arbitrary models of dividend expectations, our suggested method compares the reaction of stock and option prices to dividend announcements. Our measure is compared to commonly used model‐based measures, to a Box‐Jenkins time‐series‐based measure, and to a Value‐Line Investor Survey ‐based measure of dividend surprises. The new measure is more highly correlated with the market's reaction to the announcements than are alternative measures of dividend surprises. The new measure is also shown to be insensitive to the extent to which the options used to identify unexpected dividend announcements are in‐ or out‐of‐the‐money.

Periodic antitrust attacks on corporations may have influenced stock prices. For the period 1904 to 1944, each antitrust case filed is associated with a 0.5 to 1.9 percent drop of the Dow, and each unexpected case with even larger drops. Other aspects of antitrust besides actual filings may help account for other movements, in particular the 1929 Crash. Historical evidence bears on the question of whether antitrust is exogenous and also links antitrust and the “corporation problem.” These results illustrate the sorts of real factors aside from changes in concurrent output that may account for stock price volatility.
