A comparison of alternative methods of updating input-output coefficients

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.     

The real action in health care

It's not taking place in the White House or Congress. The show to watch is the boisterous, free-market affair, precipitated by employers fed up with rising medical costs, and carried on by insurers and HMOs scrapping for turf.     

Crafting a public image: An empirical study of the ethics of ghostwriting

Ghostwriting is viewed by some as a necessary element for crafting an effective public image. Defenders of ghostwriting see no ethical dilemma in the practice because the audience knows the speechgiver is not necessarily the speechwriter. Alernatively, those regarding ghostwriting as unethical view the practice as deceitful. This group argues that the audience does not recognize the employment of a speechwriter and thus a speechgiver relies on the words of another to fortify personal ethos. This article examines several positions regarding the ethics of ghostwriting and discusses an empirical study testing three major positions found in ghostwriting literature. Findings from the study indicate that respondents do recognize the use of speechwriters by certain individuals in certain circumstances.Linda A.

The demographic cycle and optimal schooling choices

A model is developed that enables the authors to estimate the effects of demographic cycles on both earnings and schooling. The model is tested using data from the 1991 Korean Occupational Wage Survey. The results indicate that cohorts following large birth cohorts in the cycle choose relatively less formal schooling compared to pre-peak cohorts, and that post-peak cohorts also have lower incomes. This result concerning South Korea is consistent with findings from previous studies concerning the United States.
