Nonlinear Drift And Stochastic Volatility: An Empirical Investigation Of Short-Term Interest Rate Models

In this article I provide new evidence on the role of nonlinear drift and stochastic volatility in interest rate modeling. I compare various model specifications for the short‐term interest rate using the data from five countries. I find that modeling the stochastic volatility in the short rate is far more important than specifying the shape of the drift function. The empirical support for nonlinear drift is weak with or without the stochastic volatility factor. Although a linear drift stochastic volatility model fits the international data well, I find that the level effect differs across countries.

浅谈非税收入的管理现状及对策

政府非税收入是指除税收以外,由各级政府、国家机关、事业单位、代行政府职能的社会团体及其他组织依法利用政府权力、政府信誉、国家资源、国有资产或提供特定公共服务、准公共服务取得并用于满足社会公共需要或准公共需要的财政资金,是政府财政收入的重要组成部分.非税收入的出现,标志着我国在建立公共财政体系、强化财政职能、规范非税收入管理上,取得了在认识和管理上的突破.改革开放以来,随着经济的快速发展和政府职能不断增加以及财权的逐步分割,非税收入快速增长,已在政府收入中占据了相当高的比重.加强政府非税收入的管理和监督,是各级财政部门行使管理职能的重要方面.

An Evaluation of the Actuarial structure of manitoba crop Insurance Program and its Implications

Very little research has been done in evaluating the basic principles and assumptions of the actuarial structure for premium ratemaking in crop insurance programs. Therefore, the objectives of this study are: (a) to examine the Pearson probability distribution of actual crop yields as compared with an application of normal-curve theory to crop yields as compared with an application of normal-curve theory to crop yield distributions and in turn to crop insurance ratemaking which was suggested by Botts and Boles in 1958 [1]; (b) to evaluate the pure premium rates derived from estimated Pearson probability distributions for wheat yields in 14 crop districts of the province of Manitoba; and to establish an experience rating system for the crop insurance program based upon the estimated Pearson distribution of actual crop yields on the individual farm.     

好口碑就有好印象吗?社交媒体中奢侈品牌口碑社会属性的负面效应

社交媒体中奢侈品牌口碑的社会属性较为凸显,口碑发布者的先赋地位会影响消费者对奢侈品牌的态度。先赋地位是指个体依赖于性别、原生家庭等先天资源所获得的社会地位。本研究从社会比较的视角,探究口碑发布者先赋地位逆转口碑效价法则的机理和边界,揭示出好口碑却带来坏印象的负面效应。研究结果表明,当口碑发布者具有先赋社会地位时,其正面口碑反而引发口碑接收者的恶意妒忌情绪,使接收者产生负面品牌态度。而且,当口碑接收者有较低社会流动性感知,或口碑内容具有较高品牌显著性时,口碑发布者先赋地位的负面效应更为凸显。本研究改变了社交媒体情境强化口碑效价法则的片面认知,在实践中有助于更深层次地理解社会阶层分化感知对消费者态度的影响,并为奢侈品牌的社交媒体营销提供管理建议。
