This article highlights recent
improvements and plans for further
improvements to each of BEA’s major
regional economic accounts programs.
The improvements focus on
the acceleration of release of the estimates
and on the preparation of new
and extended estimates. There also is
a brief discussion on BEA’s research
effort to improve the regional
accounts.JEL Classification E010 相似文献

The main achievements and limitations of studies of managerial jobs and behaviour are summarized drawing upon the review articles of Martinko and Gardner (1985) and Hales (1986). Ways forward are explored by developing a map of the field for future studies, which is shown in figure 1. The figure has three aims: to show different areas for research; to help in identifying neglected areas that could be fruitful ways forward; and to show the interrelationship between different aspects of the study and thus to act as a guide for data collection. The main purpose of the article is to be a guide to what can, and what might most fruitfully, be studied, but some suggestions are also made about methods. 相似文献

The Self-concept of Black and White Women: The Influences Upon Its Formation of Welfare Dependency, Work Effort, Family Networks, and Illnesses 总被引:1,自引:0,他引:1
Abstract . The concept of “self-efficacy” is used to test the hypothesis that the negative self-concept of welfare recipients coniributes to long term psychological and material dependency on such assistance. Self-efficacy focuses on the extent to which people are able to produce and regulate events in their lives and is associated with self-imposed performance expectations. The extent to which the minority status which Blacks occupy in this society decreases self efficacy relative to Whites is examined, using information generated from structured interviews with 290 low income Black and White women. Operationalizing the concept of self-efficacy with appropriate controls for socioeconomic status, family composition and other factors results in finding no racial differences in sense of self-efficacy between Black and White women. Observed differences in patterns of receipt of public assistance are found to be more directly related to the persistence of structural barriers to upward mobility that have differential impacts on Blacks and Whites. Long term receipt of public assistance is found to adversely affect both self-worth and work orientation/perceived efficacy for all women. 相似文献

Expressions for marginal distribution functions of sequential order statistics and generalized order statistics are presented without any restrictions imposed on the model parameters. The results are related to the relevation transform, to the distribution of the product of Beta distributed random variables, and to Meijers G-functions. Some selected applications in the areas of moments, conditional distributions, recurrence relations, and reliability properties are shown.

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions,
and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite. 相似文献

The two main purposes of this paper are an introduction to the economic analysis of insurance fraud and furthermore a derivation of factors that determine fraudulent behavior of policyholders on insurance markets. Consequently, we analyze the strategic decision problems of insurance companies and the policyholders and identify some factors that can help to reduce fraudulent behavior. In this context we evaluate two derived starting points for the combat against insurance fraud: fraud detection systems and a consequent charge policy of detected defrauders. We illustrate that both points can help to reduce the cost of fraud. Furthermore, we enhance our earlier analysis with respect to the empirical fact that some individuals care about fairness or — in the insurance fraud context — the legitimacy of their actions. Surprisingly, in some market situations these concerns of some policyholders do not lead to a lower fraud probability. Finally, we discuss how and to what extent insurance companies can influence such ethical concerns of policyholders. On that score, we distinguish insurance specific and insurance unspecific factors and their impact on the consumers attitudes towards insurance fraud. 相似文献
