Social security and private saving: theory and historical evidence

This article is a nontechnical presentation of the debate that has gone on during the past decade over whether the U.S. social security system has depressed private saving in the economy. The heart of the article is an assessment of economist Martin Feldstein's original evidence, presentation of the alternative evidence that concluded that currently available historical data do not support the proposition that social security reduces private saving, and an evaluation of the contradictory evidence presented by Feldstein in response to the alternative evidence. The article concludes that, although the total body of evidence is inconclusive, the historical evidence fails to support the hypothesis that social security has reduced private saving. The Office of Research, Statistics, and International Policy, as part of its ongoing research mission, investigates the interrelationship between social security and the economy. This article presents an examination of one of several aspects of this relationship relevant to public policy considerations and is intended to make previously published technical papers available to a broader audience.     

The effects of health care advertising

This paper begins by assessing the current status of health care advertising and its potential for growth, arguing that this form of marketing is not just a passing fad among a few clinics and hospitals. It then describes the opposing schools of thought concerning the economics of advertising, and considers both theory and evidence on the effects of advertising on prices, profits, quality, utilization, and innovation.     

A new method for detecting diatoms in human organs

A new method for diatom detection is described. It includes an ultrasonic irradiation procedure with the use of a tissue solubilizer. The method is easy to carry out and is less time-consuming than previous techniques.     

A MUNICIPAL LAND POOLING PROJECT IN PERTH

Planning control of urban land use in most of the Australian States is by the planning scheme system and is authorized by legislation based on the English Town and Country Planning Act, 1932. Under this system each planning authority prepares a land use zoning and reservation plan designed to accommodate the forecast urban growth. It then reviews and regulates the proposals for urban development projects as they are brought forward to ensure that they conform to the plan.     

THE JUSTICE SYSTEM AND SENTENCING The Importance of Race in the Military

Data on incarcerated Navy and Marine Corps personnel are examined to determine the impact of offender's race on sentence length. The literature on sentencing in the civilian sector has long suggested that under certain circumstances blacks (or whites) receive unjustifiably long sentences. It is argued here that much of the variation in senate is due not just to characteristics of the offender, but also to characteristics of the sentencing process. The military forms a more state sentencing environment than the civilian setting; hence one should expect less variation due to the sentencing process. Analysis revealed that blacks and whites showed no statistically significant differences in sentence length, in both the Navy and Marine Corps. When small differences did exist. whites were usually recipients of the longer sentences.
