This article will focus mainly on utility electric plant maintenance with particular emphasis on steam (nonnuclear) turbine-generator maintenance. Our objective has been to identify and examine relationships between the target market and other recorded key operating parameters that would be useful for future forecasting of trends in the target market. 相似文献

The purpose of this study is to consider the question of whether characteristics of applicants for federally subsidized housing can be used in predicting whether one is accepted or rejected by management as a tenant. Using probit analysis, a statistical model was developed for use in assisting management in objectively screening applicants. Factors found significant in determining the probability of acceptance or rejection were credit ratings, character references, length of time employed, and student status. The percent of rent subsidized by government and sex of household head had little effect on applicant acceptance. Although a meaningful model for estimating the probability of eviction could not be developed, low eviction rates resulting from the tenant selection model suggest that it may serve as a reasonable proxy. 相似文献

Listing Price, Time on Market, and Ultimate Selling Price: Causes and Effects of Listing Price Changes 总被引:4,自引:1,他引:4
John R. Knight 《Real Estate Economics》2002,30(2):213-237
Information about price changes during a home's marketing period is typically missing from data used to investigate the listing price, selling price, and selling time relationship. This paper incorporates price revision information into the study of this relationship. Using a maximum-likelihood probit model, we examine the determinants of list price changes and find evidence consistent with the theory of pricing behavior under demand uncertainty. Homes most likely to undergo list price changes are those with high initial markups and vacant homes, while homes with unusual features are the least likely to experience a price revision. We also explore the impact of missing price change information on estimating a representative model of house price and market time. Our results suggest that mispricing the home in the initial listing is costly to the seller in both time and money. Homes with large percentage changes in list price take longer to sell and ultimately sell at lower prices. 相似文献

Competition in telecommunications 总被引:1,自引:0,他引:1
John Langdale 《Telecommunications Policy》1982,6(4):283-299
The author examines the impact of competition from both domestic and international perspectives. He provides a critique of the pro-competition argument, although a number of advantages of competition are also outlined. The advantages are discussed in relation to equipment and services. International trends towards competition are then described and the disadvantages of such trends are debated in relation to cross-subsidization, interconnection, the telecommunications manufacturing industry, and the market structure. Finally, competition in the international arena is discussed. 相似文献
