SECURITIES OFFERINGS AND CAPITAL STRUCTURE THEORY

This paper analyzes a large sample of public security offerings to determine the motivation to issue debt or common equity. The results provide new evidence that the existence of asymmetric information plays a key role in firms' choice of security. Bankruptcy risk appears to affect the issue decision, but other traditional capital structure considerations do not. Variations in the determinants of security choice over time suggest a dynamic aspect to capital structure decisions not recognized in previous studies.     

The Effect of Option Trading on the Structure of Equity Bid/Ask Spreads

This paper investigates empirically the direct effect of option trading on the structure of costs that comprise the underlying equity bid-ask spread. Our results show that the spread declines over a 30-day period following initiation of option trading, but the decline vanishes when price, volume, and volatility effects are considered. Changes in the composition of the spread reflect primarily a reduction in adverse information costs. Additionally, consistent with previous research, we find significant transaction-type clustering in our intraday data.     

The Relationship Between Stock and Option Price Changes

This paper documents an important step in reconciling conflicting results by Manaster and Rendleman [16] and Stephan and Whaley [21] regarding price change relationships between options and their underlying stocks. Using recent advances in bi-directional causality testing and data sources available only fairly recently, statistical tests are conducted that mitigate the nonsynchroneity and bid-ask bias problems that may have affected the Manaster and Rendleman [16] study. Even with these adjustments, empirical results are consistent with Manaster and Rendleman [16], indicating that stock price changes adjust to lagged option price changes over two trading days. Moreover, results suggest that the causality is bi-directional.     

U.S. Equity Markets and Environmental Policy. The Case of Electric Utility Investor Behavior During the Passage of the Clean Air Act Amendments of 1990

We examine electric utilityinvestor reaction surrounding twenty-twomilestones associated with the passage of theClean Air Act Amendments of 1990. Resultssuggest that investors did not react sharply tothe passage of the Amendments. To the extentthat statistically significant effects wereobserved, we interpret the results as moreindicative of investor concern over resolutionof uncertainty surrounding the politicalprocess and resulting provisions than ofconcern over the expected costs of compliancefollowing passage of the Amendments. Weobserved little, if any, difference betweenutilities subject to Phase I restrictions andthose not subject to Phase I. Finally, changesin monthly excess returns appear to haveresulted from changes in U.S. interest ratesand investor concern over power industryderegulation. We view our results as importantbecause any wealth effects due to environmentalregulations represent a real economic costassociated with their implementation. In thissense, we view the results as good news forU.S. environmental policy makers.     

Investment Irreversibility,Cash Flow Risk,and Value‐Growth Stock Return Effects

We simulate results from a simple real options model to provide insight into the value‐growth stock return anomaly. In our model, firms possess either single (“value” firm) or multiple (“growth” firm) investment opportunities. Our model predicts that growth firms: (1) invest sooner, (2) exhibit greater continuity in capital expenditure over time, (3) have lower book‐to‐market ratios, and (4) generate lower rates of return than value firms.     

Corporate debt,corporate taxes and leasing

This paper utilizes recent developments in capital lease modeling to develop a new specification of the relationship between the expected returns to debt, levered equity and unlevered equity for firms that lease a portion of their assets. Accounting explicitly for leases is shown to be important when the difference between equity and debt risk is large, when the risk of leased assets differs from the firm's other assets and when salvage value is a significant portion of the capitalized value of the firm's lease obligations. This new specification yields improved estimates of firms' unlevered cost of capital, thereby facilitating improved capital budgeting decisions in those that lease a significant portion of their assets.     

A real options approach to valuing and negotiating licensing agreements

We apply real options modeling to a common pharmaceutical industry licensing arrangement to take into account various uncertainties and the flexibility value. The managerial flexibility is limited to the project abandonment option. We extend previous work by incorporating the phases required to bring the project from patent approval to market. We also incorporate a deterministic variable into the cash flow process that provides a realistic product lifecycle. We focus on the allocation of project value between licensor and licensee, i.e., the so-called “profit split” ratio (PSR) because it is commonly used in practice to negotiate terms. We find: (1) Ignoring the managerial flexibility in valuation may cause the licensee to either forego an acceptable deal or enter into an inferior deal. (2) The magnitude of project profitability as well as cost and sales uncertainty affects the licensor's bargaining power over compensation for granting abandonment flexibility to the licensee. (3) Managers must exercise care when estimating sales volatility because the flexibility value is more sensitive to sales volatility than it is to cost volatility. (4) Failure to incorporate the product lifecycle will produce suboptimal capital investment decisions.
