Design and analysis of delivery ‘pipelines’ in truckload trucking

This paper examines a new dispatching alternative for the truckload trucking industry involving the use of delivery ‘pipelines’ with dense flow volumes. Drivers and loads are partitioned into two sets; those that utilize pipelines via a series of ‘dray’ moves and line-hauls, and the remaining set of random over-the-road (OTR) drivers that are dispatched by traditional methods. Alternative methods are presented to determine where delivery pipelines should be located and how they should be operated. The effects of the pipelines on the remaining OTR fleet are also examined. Results indicate that the new dispatching alternative is feasible.     

INTRAINDUSTRY SPECIALIZATION AND THE UNITED STATES–CENTRAL AMERICA–DOMINICAN REPUBLIC FREE TRADE AGREEMENT

This paper examines changes in intraindustry specialization indicators over the 1992–2004 period to assess the potential for structural adjustment problems that may arise in the United States with growth in trade resulting from the United States–Central America–Dominican Republic Free Trade Agreement (CAFTA‐DR) between the United States and six Central American countries—Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and the Dominican Republic. CAFTA‐DR will expand market access for US exporters. Few US industries are likely to encounter structural adjustment problems. Given the relatively large size of the US economy, and the small number of industries that face potential adjustment pressures, the United States should have liberalized all trade immediately. When potential adjustment pressures are indicated, long tariff phaseouts, complex rules of origin, and import safeguards are used to delay factor adjustments in import‐sensitive industries.

Baylor University Roundtable on The Corporate Mission, CEO Pay, and Improving the Dialogue with Investors

A small group of academics and practitioners discusses four major controversies in the theory and practice of corporate finance:

• • What is the social purpose of the public corporation? Should corporate managements aim to maximize the profitability and value of their companies, or should they instead try to balance the interests of their shareholders against those of “stakeholder” groups, such as employees, customers, and local communities?
• • Should corporate executives consider ending the common practice of earnings guidance? Are there other ways of shifting the focus of the public dialogue between management and investors away from near-term earnings and toward longer-run corporate strategies, policies, and goals? And can companies influence the kinds of investors who buy their shares?
• • Are U.S. CEOs overpaid? What role have equity ownership and financial incentives played in the past performance of U.S. companies? And are there ways of improving the design of U.S. executive pay?
• • Can the principles of corporate governance and financial management at the core of the private equity model—notably, equity incentives, high leverage, and active participation by large investors—be used to increase the values of U.S. public companies?

     

Failures to Deliver,Short Sale Constraints,and Stock Overvaluation

Studying a large sample of publicly available data on failures to deliver, we find that stocks reaching threshold levels of failures become significantly overvalued. Where short sale constraints are especially binding, we report extreme overpricing and subsequent reversals. These findings support the overvaluation hypothesis, although the mispricing is likely to be difficult to arbitrage because of extreme shorting costs. In addition, threshold stocks with low short interest become more overvalued than threshold stocks with high short interest. This suggests that the level of short interest reflects supply‐side effects when the examination conditions on the difficulty of borrowing shares.     

TIME SERIES ANALYSIS OF ACCOUNTING POLICY CHOICE: REPLY

Taylor (1992) argues that accounting policy choices in any year are not assessed independently of policy choices adopted in previous years. This independence assumption is a maintained hypothesis of Anderson and Zimmer (1992). Although Taylor acknowledges that our results remain robust to his suggested adjustments for non-independence, we argue in this reply that such adjustments are unnecessary because temporal independence of accounting policy choices is consistent with the implications of costly contracting between the firm and its claimholders. We develop the arguments that (1) accounting choices are temporally independent and our research design is therefore, appropriate (2) to the extent that there is an independence problem of the type proposed by Taylor (1992) it also applies to cross-sectional studies of accounting policy choice.     

The revival of shelf-registered corporate equity offerings

We report that traditional seasoned equity offerings (SEOs) are no longer firms' preferred choice for raising seasoned public equity. Traditional offerings have recently been surpassed by shelf-registered offerings in terms of both annual frequency and total capital raised. This represents a dramatic shift from the 1980s, during which the overwhelming majority of firms favored traditional over shelf-registered offerings. We find that the growth in shelf use is related to firms increasingly valuing and using the option feature of shelf registration to defer offerings. Moreover, the evidence indicates that the way firms now use shelf offerings resolves the shelf under-certification problem and results in no larger market penalties and significantly lower underwriter fees relative to non-shelf offerings. Finally, firms often use universal shelf filings and choose between debt and equity offerings based on the prevailing relative market conditions.     

Dividend Forecast Biases in Index Option Valuation

Since the early days of option pricing theory,the assumption that the dividends on the underlying stock or index over the life of the contract are known has not been challenged. We examine the sensitivity of index option prices to the assumption of dividend uncertainty. We consider a number of issues related to the forecasting of dividends and build a dividend forecasting model that passes several rigorous tests for unbiasedness. We then generate option prices using contemporary market levels and interest rates. We find that prices generated with the actual dividends are unbiased with respect to those generated using the forecasted dividends. The magnitudes of the forecast errors, however, are sufficiently large to suggest a concern, but the percentage errors are consistently small, typically amounting to less than two percent of the option price. We conclude that the convenient assumption that the stream of future dividendsis known is probably innocuous.
