Properties of technical efficiency estimators in the stochastic frontier model

This paper considers the disturbance specification ε = v ? u of the stochastic frontier model. For v distributed zero-mean normal and u half normal or exponential, we evaluate the population correlation coefficients between u and three estimators of u, E(u|ε) and two linear estimators, for various values of the signal-to-noise ratio.     

The professor-consultant: An important marketing resource

There has been little published on the topic of marketing consultants. The literature void is even more pronounced when a major source of outside expertise, the professor-consultant, is examined. The authors have surveyed marketing academicians to determine their attitudes toward consulting and the scope and nature of their consulting activities along with the kinds of clients for whom they work. The findings show that professors hold generally favorable attitudes toward consulting and work in a wide range of topical areas while serving many diverse clients.     

Technology Transfer to the Private Sector: A Field Study of Manufacturer Buying behavior

Public sector R&D is an important source of new product technologies and concepts. If the transfer of these technologies to private sector manufacturers is viewed from a marketing perspective, manufacturing organizations can be analyzed as industrial "buyers." David Large and Donald Barclay report on case-based research that explores this technology buying process. Findings are induced that suggest: user value, patent/proprietary position, prototype efficacy, and strategic fit are the most important attributes of the transfer proposal; and business empathy and credibility are the most important attributes of the transfer agent. The R&D director is identified as a key influencer in the transfer decision and represented by a model of the director's attitude toward technology transfer proposals. The authors develop implications for public sector managers/agents and suggest opportunities for further research.     

Government Budgets and Public Services: Some Criteria for Determining the Sources and Levels of Public Goods, including Transport Services

Instances of non-optimal consumption of public goods and services can easily arise if individual demand curves are not identical. It does not follow, however, that the best solution to the problem of too little consumption is an increase in government expenditure. Special user charges and voluntary contributions of time, goods, and money on the part of persons that value public goods more highly than the general population have long been important ways of supplementing government spending for social goods. The work trip appears to be a good example of a service area where existing cost structures and pricing methods may be biased against the voluntary associations which are needed to make the United States less dependent on foreign oil. This bias could be corrected by using an income-tax-surcharge to help finance the fixed costs associated with mass transit and other types of work trip pooling arrangements.     

Racial Discrimination and Mortgage Lending

Looking at a sample of conventional fixed-rate mortgages, this paper examines whether lending practices are consistent with the competitive hypothesis that the racial and ethnic composition of the borrower??s neighborhood affects the contract rate charged only to the extent that these characteristics objectively influence the probability of the loan defaulting or prepaying. Our results, however, reject this hypothesis, showing instead that borrowers in predominantly black neighborhoods pay a significantly higher contract rate than is consistent with evidence of their behavior.
