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. 相似文献

Although the level of crime varies dramatically across the urban-rural dimension, little research has been directed at the issue of the patterns of offending across this dimension. Using National Crime Survey (NCS) victimization data, this paper examines to what extent the patterns of offending by particular age, race, and sex subgroups are similar in urban and rural areas. It was found that the patterns of age, race, and sex offending are essentially the same in both urban and rural areas. Particularly impressive is the consistency in the rankings (from high to low) of the propensity of offending in urban and rural areas when age, race, and sex were examined simultaneously. Also, these NCS data generally parallel Uniform Crime Reports arrest data with respect to the offender characteristics of age, race, and sex. This suggests that existing criminological theories can be applied to rural, as well as urban, crime patterns regarding the issue of offender characteristics. 相似文献
