The Lowry Model Revisited: Incorporating a Multizonal Input-Output Model into an Urban Land Use Allocation Model

This paper formulates a new generation of Lowry-style models that combine a multizonal input-output model and an urban land use allocation model. Three different types of models are proposed: 1) an unconstrained model, 2) a primal of a linear programming approach that includes land supply constraints, and 3) a modified dual of the linear programming approach that allocates land based on additional conditions of economic efficiency. The modified dual formulation improves upon the limitations of Lowry models and their derivatives. First, the proposed model has sound theoretical underpinnings that incorporate the production theory of input-output models and the behavioral theory of optimization models. Second, the proposed model allocates land on the basis of economic efficiency by imposing a procedure that equalizes shadow prices. And third, the proposed model is an optimization model that fully accounts for the spatial and sectoral relationships of multiplier effects determining land use demand.     

Developing a cost-benefit analysis process for small-to-moderate expenditure decisions

During the Reagan administration, the federal government mandated the use of cost–benefit analysis (CBA) for regulatory decisions involving $100 million or more. While the use of CBAs has increased, less attention has been given to CBA processes involving smaller expenditures (regulatory and nonregulatory). As the federal budget tightens in the years ahead, the need to make hard decisions about these policies, programs, and technologies will increase. This paper describes a CBA process developed for the Office of Strategic Planning of the Social Security Administration; it was designed to handle small-to-moderate expenditure decisions (or for preliminary estimates of larger undertakings). A sample CBA using this process is provided, along with a discussion of the lessons that were learned from an initial application.     

EQUITY-EFFICIENCY PREFERENCES IN Poland AND THE SOVIET UNION: ORDER-REVERSALS UNDER THE ATKINSON INDEX

In this paper, the relation between inequality and welfare index "reversals" is characterized. By the identification of these reversals, upper and lower bounds are established for Atkinson's parameter of inequality aversion. This exercise shows that a level of inequality aversion high enough to show welfare improving over the "egalitarian decline" of 1978–81 in Poland is too high to show improvement over the "elitist growth" of 1981–86 in the Soviet Union. However, even if the lower bound of inequality aversion is assumed, plausible projections on Soviet growth and distribution still show social welfare declining.     

Tax noncompliance: The role of tax morale in smokers' behavior

Measuring and predicting compliance with tax obligations is an important but challenging task. Survey data from California smokers show that several forms of tax avoidance and evasion were common. The analysis shows that 43% of smokers avoided taxes by purchasing cigarettes from out-of-state sources in the past year, 15% admitted to evading taxes through cross-border purchases, and 26% reported purchasing likely or certainly untaxed cigarettes in the state in the past month. Attitudinal factors related to tax morale explain much more of the variance in compliance rates than demographic or law-and-economics factors. The implications for policy are discussed.     

Arbitrators’ characteristics and decision-making records,gender of arbitrators and grievants,and the presence of legal counsel as predictors of arbitral outcomes

Labor arbitration helps define employee and employer rights and responsibilities. Evidence indicates that the advocates at arbitration tend to concern themselves with issues unrelated to the facts of the case or to the rights and responsibilities of the parties involved. More specifically, before the hearing, management and union advocates often dwell on issues such as the importance of the arbitrators’ personal characteristics and their decision-making history, the likely effects of the gender of arbitrators and grievants, and whether the presence of legal counsel impacts the arbitral outcomes. The purpose of this study is to examine whether these non-case-related factors actually can be associated with differing awards by arbitrators. This study may be the first in which the arbitrators’ decision-making history (award orientation) is a primary issue. Of all the issues studied, the arbitrator’s disciplinary award orientation is the only one with a consistent impact on arbitral outcomes. We conclude that the energy and resources expended by the advocates concerning non-case-related issues would be better spent in preparing their cases for arbitration and in examining the potential impact of arbitration on the rights and responsibilities of management and its employees.     

Institutional investors, antitakeover defenses and success of hostile takeover bids

In this study we investigate the question of whether institutional investors enhance or reduce efficiency in the market for corporate control. In particular, given unequivocal evidence that target stockholders gain in successful takeover bids, we investigate the impact of institutional ownership in target firms on the adoption of the type of antitakeover defense as well as the outcome of takeover bids. We find that target firms are more likely to adopt value-reducing antitakeover defenses and successfully thwart takeover bids when a higher percentage of target common stock is owned by ‘pressure-indeterminate’ investors (investment counsel firms in particular). On the other hand, the probability of a successful takeover rises with the ownership of both ‘pressure-sensitive’ and ‘pressure-resistant’ investors. The above findings support the view that institutional investors do not play a homogeneous role in the market for corporate control.     

Training Employees for African Statistical Offices

A review of the organizational set-up of a national statistical office, its staffing levels and subjects covered has been described. Two groups of employees of a statistical office are considered with respect to the teaching of statistics, namely those already in employment and those expected to be employed by a statistical office. The Statistical Training Programme for Africa (STPA), under which the present study was undertaken, improvement and strengthening of statistical training programmes for employees or expected employees of a statistical office, are described including selected aspects of the programme. Teaching programmes for those currently in employment with the objective of improving their work performance are also described. Achievements and problems of the programme are given. In conclusion a new framework for revitalisation of teaching of statistics in Africa in the 1990s is mentioned.     

The Benefits of Visibility Improvement: New Evidence from the Los Angeles Metropolitan Area

This article examines the impact of a specific aspect of air quality—visibility, or the ability to clearly see distant objects—on housing values. Our analysis is based on a data set constructed by matching residential housing sales data from the Los Angeles Metropolitan Area for the period 1980 through 1995 with visibility and other air pollution data and other characteristics. We find that visibility differences are capitalized into housing values, producing a measurable hedonic price gradient. The time-series design facilitates an estimate of the demand for visibility that we use to calculate the benefits of changes in visual range.
