This paper explores how property-right assignment affects social efficiency when a public program has both “public good” and
“public bad” components. We show that when willingness to accept a public bad exceeds the willingness to pay, the net benefit
is unambiguously lower when the property right supports the status quo institutional structure. Thus, Kaldor–Hicks efficiency tests tend to favor
public programs and mitigation over the status quo even when mitigation negatively affects another group. To illustrate the
result, we develop social-cost estimates for moving nuclear waste from current temporary-storage facilities to a permanent
central repository at Yucca Mountain, NV, USA. For a representative city with a population of 226,195, the present value of
the external cost of shipping waste is $1.42 billion when those living near temporary nuclear-waste storage facilities are
assigned the property right to “health and safety.” That number swells to $5.95 billion when those living near the transport
route are assigned the property right. Thus, property-right assignment affects the efficient level of nuclear-waste, and thus
nuclear energy, produced. 相似文献

The argument presented in this paper is that the adoption of sophisticated postaudit procedures should be associated with improved firm performance. Based on a matched-pair experimental design, utilizing the Wilcoxon matched-pairs signed-ranks test and a newly developed statistic to test for a change point, empirical evidence is provided to support this argument. 相似文献

The central concern of this paper is with the treatment of human resources in dynamic applications of capital and growth accounting. Despite many advances, national accounting conventions still give biased profiles of the economy, but the time is ripe for experimentation with measures that can correct those biases and provide a more adequate base for assessment of long-term economic performance and prospects.
In the first section, the logic and feasibility of forward and backward measures of formation of human capital in the simplest case (of full-time schooling) is examined in parallel with physical capital. In a dynamic economy, which is rarely if ever in equilibrium, these approaches complement each other; they are poor substitutes. In section two a number of conceptual and measurement issues are considered with particular reference to human-capital investment periods and the treatment of appreciation, depreciation and obsolescence of human versus physical capital. Here special attention is given to the extended periods of investments in human resources, which overlap with realization of returns, and to the processes and agencies through which postschool investments are made. The last section presents a brief statement concerning asymmetries in disequilibrium biases with respect to the formation of human relative to physical capital. Drawing upon section 1 with regard to forward and backward measures and section 2 with regard to the critical importance of postschool learning, new possibilities in contributions of national accounting to a dynamic analysis of economic development are suggested. 相似文献

The variables that relate to cost of hospital care for a large sample of elderly patients at risk for falling are examined. The chief predictors of cost of hospitalization were medical, pharmacy, and nursing interventions. Use of nursing interventions, on average, raised the median hospital cost less than use of medical or pharmacy interventions. Using a standardized nursing language with the hospital's information system can provide nurses with information that demonstrates the cost effectiveness of their interventions. 相似文献

We propose a simple procedure, based on an artificial linear regression, for consistently estimating the covariance matrix of the parameter estimates for linear regression models with serially correlated errors and lagged dependent variables. 相似文献

This article describes and generalizes a validation study of four commercially available personal financial planning expert systems and the rationale for the research methodology used. Our evaluation of these systems adds to the understanding of verification and validation issues related to case selection, validation standards and evaluator bias. The article describes the systems, their domain and the empirical method—field tests using hypothetical cases—and relates that method to the literature. Comparing same-task systems combines multiple system perspectives and multiple models. Our methodology did efficiently and effectively identify conflicting terminology, omissions and system weaknesses but was inadequate for comparing the complex plan recommendations. The results re-emphasize the importance of continual knowledge base updating, formal system testing and the need for external evaluation. The results also show the value of comparing multiple, same-task systems. 相似文献
