Taylor AK 《Public policy》1979,27(2):203-225
This study examines the rapid growth of hospital wage rates and employment levels over the past decade, with particular attention to the period 1971-73, when wage and price controls were in effect throughout the economy. The analysis shows that the hospital regulations under the Economic Stabilization Program reduced real hospital wages below what they would have been in the absence of controls; a similar but smaller effect of the controls on hospital employment levels is also shown. This suggests that if the current HEW proposal for hospital cost containment is enacted, its impact would be a significant decrease in the rate of growth of hospital wages and employment. 相似文献

This article examines inter-relationship between "centers" and "peripheries" within political, professional and health care systems. It seeks to determine which conditions tend to improve the capacity of public authorities to further such measures of effectiveness as access to, quality of, and complementarity of health care delivery. Examples are selected from the experience of the United States and West European countries. 相似文献

Social welfare functions when preferences are convex,strictly monotonic,and continuous 总被引:1,自引:0,他引:1
The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R + n , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship. 相似文献

Recent literature reflects the increased use of RIA as a qualitative and quantitative tool. This study exemplifies the problems that may arise when this technique is used for quantitation. Caution must be exercised, and a physiological and toxicological understanding of each particular drug is essential to provide credible results. It is evident that the sensitivity and ease of the RIA method for methaqualone makes it invaluable as a screening test, but confirmation and quantitation of this drug must remain with those methods that can quantitate each metabolite. 相似文献
