TRUCKING DEREGULATION AND MOTOR-CARRIER PERFORMANCE: THE SHAREHOLDERS' PERSPECTIVE

This paper utilizes an event study methodology to investigate the effects of deregulation on carriers' shareholders. This methodology compares the expected returns during a time period surrounding a particular event with actual returns during the same time period. These differences are referred to as prediction errors. The study investigates the prediction errors associated with individual trucking firms, as well as those associated with groups composed of regional carriers, national carriers, and the aggregate sample of firms used in the study. The results suggest that the passage of the Motor Carrier Reform Act on July 1, 1980, halted a serious 18-month downward trend in the aggregate sample's cumulative prediction error. Nearly all firms showed significant gains in the 18 months subsequent to deregulation. Using two control groups, the authors show that a large portion of this gain from the industry sample can be explained by lower and more stable fuel prices and a sharp upturn in the economy. The results also indicate that due to deregulation, the large regional trucking firms were able to outperform the small regional firms and the national firms in the more favorable economic environment present after deregulation.     

Interstate banking and the payments system

Interstate banking will improve the efficiency of the payments system. This will occur because the number of handlings for multiple-bank payments (transit items) will fall and because some multiple-bank payments will be transformed into single-bank payments (on-us items). These effects are simulated using data on the current cross-section relationship between banking structure and check clearing patterns in a multinomial logit model. The Federal Reserve, which currently processes almost one-third of all checks, is predicted to lose 43 to 60 percent of its market share. The annual impact is expected to be gradual, however, since interstate banking will be phased in and because of offsetting growth in the total check clearing market.     

APPLICATIONS OF DECISION TREES TO THE EVALUATION OF APPLIED RESEARCH PROJECTS

Abstract I n this paper two applications of decision trees are described. These relate to the electronics and chemical industries and are concerned with the evaluation of applied research projects aimed at new products. It is demonstrated that decision tree diagramming is a demanding yet flexible technique which allows the representation of sequential decisions and subjectively based data in a readily understood form.     

Foreign owners and American cement: Old cartel hands,or new kids on the block?

In 1961, all portland cement producing capacity in the United States was owned by companies domiciled here. Thirty years later, about 70% was controlled by foreign owners, mostly European. It has been suggested by various authorities — academic economists, the business press, even cement executives — that foreign governments' tolerance for formal or tacit collusion would bring the American cement industry a kind of ‘price discipline’ that it has been largely unable to practice since 1948. This contention is tested as an hypothesis, using regional data from the U.S. Bureau of Mines and the Portland Cement Association. The test shows either no or a negative relation between foreign control and the level of regional cement prices. At the same time, we observe the traditional positive relation between concentration (HHI) and prices. The results imply that horizontal mergers between cement producers are a better subject for the attention of public policy than where they are owned.     

OVER-REACTIONS IN US AGRICULTURAL COMMODITY PRICES

The purpose of this paper is to test rationality in agricultural commodity markets. We investigate the price-adjustment process after significant events using abnormally large cash commodity price changes as proxies for the arrivals of significant events in the markets. The evidence suggests that market rationality is violated. Generally, agricultural commodity prices tend to reverse after significant events. This is consistent with the over-reaction hypothesis which maintains that traders in spot commodity markets over-weight more recent information and under-weight prior information in their expectations.     

The Role of Banks in Dividend Policy

We use loan‐specific data to document a significant inverse relation between a firm's dividend payouts and the intensity of a firm's reliance on bank loan financing. Banks limit dividend payouts to protect the integrity of their senior claims on the firm's assets. Moreover, dividend payouts decline in the presence of monitoring by relationship banks, which acts as an effective governance mechanism, thereby reducing the gains from precommitting to costly dividend payouts. Bank monitoring and corporate governance (insider stake and institutional block holdings) are complementary mechanisms to resolve firm agency problems, both reducing the firm's reliance on dividend policy.     

The new retirement reality: calculating the true cost of retirement income adequacy

Recognizing that 401(k) plans are emerging as many employees' sole source of employer-sponsored retirement income, plan sponsors are increasingly adding paternalistic plan features to increase the amount--and effectiveness--of dollars invested in 401(k) accounts. The authors describe the results of a study they prepared for Hewitt Associates that assesses retirement income adequacy for individuals represented in a plan participant database of 1.8 million individuals. The study includes analysis of retirement income adequacy for the aggregate population as well as the results for different subgroups, reflecting factors such as whether individuals actively contribute; the impact of different levels of retiree medical coverage; and the presence of a defined benefit pension. Finally, the authors discuss how plan sponsors can bolster the adequacy of retirement income from 401(k) plans, depending on employer objectives.
