WEALTH AND THE DISTRIBUTION OF INCOME: PERMANENT AND TRANSITORY EFFECTS

This paper examines the permanent and transitory effects of changes in wealth, the top federal marginal income tax rate, and capital gains tax rate on the distribution of Adjusted Gross Income (AGI). This paper establishes the importance of wealth in determining the distribution of AGI, and results here suggest that its effects can negate the permanent effect of a change in both tax rates. Of the two tax rates, the capital gains tax rate is the most important for AGI distribution. The marginal income tax rate is notably less important for long run behavior, but does have short run impacts.

Interest rate rules, inflation and the Taylor principle: an analytical exploration

Summary. The purpose of this article is to characterize optimal interest rate rules in the framework of a dynamic stochastic general equilibrium model, and notably to scrutinize the “Taylor principle”, according to which the nominal interest rate should respond more than one for one to inflation. This model yields explicit solutions for the optimal rule. We find that the elasticity of response depends on numerous factors, such as the degree of price rigidity, the autocorrelation of the underlying shocks, or which measure of inflation is used. In general the optimal elasticity of the interest rate with respect to inflation needs not be greater than one.Received: 6 November 2003, Revised: 17 August 2004 JEL Classification Numbers: E5, E52, E58.J.-P.

我国车险市场承保周期的实证研究——费率管制与市场准入限制的影响

对车险承保周期的研究,传统上是从“价”的角度着手,以单位价格(保费/赔付额)和承保利润率为指标,来考察承保周期的波动特征.然而,我国车险市场中存在两个特殊的局限条件:费率管制和市场准入限制.费率管制的存在,使保费收入不能反映车险业务的真实情况,从而以保费为基础的传统研究指标也不能用于对我国车险市场的研究.基于此,文章转换分析的角度,从“量”入手,以赔付额来描述车险市场的承保周期.文章发现,我国车险市场存在承保周期,周期平均长度为5.33年,并且市场准入限制是影响车险承保周期的重要原因.     

Linking thoughts to feelings: Investigating cognitive appraisals and consumption emotions in a mixed-emotions context

While emotions have been shown to have significant influence on various consumer behaviors, the cognitive appraisals linked to consumption emotions have not been fully explored. This research investigates how individuals' cognitive interpretations of situations correspond to the emotions they experience in these contexts. Using analysis of variance and multiple discriminant analysis, our results show a systematic relationship between cognitive appraisals and 10 consumption emotions. The author's findings offer theoretical insights into these consumption emotions, the appraisal/consumption emotion correspondence, basisversus subordinate-level category differences in emotions, and mixed consumption emotions. The findings provide a practical framework for academics and practitioners interested in better understanding and managing consumption emotions. Julie A.

U-commerce: Expanding the universe of marketing

This article introduces several new concepts that lay the conceptual foundation for thinking about next-generation marketing based on ubiquitous networks. U-commerce, orüber-commerce, is predicated on the characteristics of network ubiquity, universality, uniqueness, and unison. It is proposed that the keys to managing network-driven firms are the concepts of u-space and attention analysis. The implications for next-generation marketing in the u-space are explored, with a research agenda identified for scholars and managerial implications recognized for practitioners. Richard T.

Aspects of statistical analysis in DEA-type frontier models

In Grosskopf (1995) and Banker (1995) different approaches and problems of statistical inference in DEA frontier models are presented. This paper focuses on the basic characteristics of DEA models from a statistical point of view. It arose from comments and discussions on both papers above. The framework of DEA models is deterministic (all the observed points lie on the same side of the frontier), nevertheless a stochastic model can be constructed once a data generating process is defined. So statistical analysis may be performed and sampling properties of DEA estimators can be established. However, practical statistical inference (such as test of hypothesis, confidence intervals) still needs artifacts like the bootstrap to be performed. A consistent bootstrap relies also on a clear definition of the data generating proces and on a consistent estimator of it: The approach of Simar and Wilson (1995) is described. Finally, some trails are proposed for introducing stochastic noise in DEA models, in the spirit of the Kneip-Simar (1995) approach.     

Survival strategies in the era of managed care

The era of managed care has forced an unprecedented restructuring of the health care environment. As hospitals downsize in response, materiel managers should consider adopting strategies that may help ensure their survival, including innovative approaches to supply management and the development of individual responses that will best position them to succeed in this new reality.
