Jackknifing Bond Option Prices

Prices of interest rate derivative securities depend cruciallyon the mean reversion parameters of the underlying diffusions.These parameters are subject to estimation bias when standardmethods are used. The estimation bias can be substantial evenin very large samples and much more serious than the discretizationbias, and it translates into a bias in pricing bond optionsand other derivative securities that is important in practicalwork. This article proposes a very general and computationallyinexpensive method of bias reduction that is based on Quenouille's(1956; Biometrika, 43, 353–360) jackknife. We show howthe method can be applied directly to the options price itselfas well as the coefficients in the models. We investigate itsperformance in a Monte Carlo study. Empirical applications toU.S. dollar swap rates highlight the differences between bondand option prices implied by the jackknife procedure and thoseimplied by the standard approach. These differences are largeand suggest that bias reduction in pricing options is importantin practical applications.

论价值链会计管理框架

本文从价值链理论与会计管理理论出发,分析了一个基于价值链分析的会计管理框架,该框架以时间序列为基础,并结合了不同价值链的特点,具体包括事前的预测、决策和预算,事中的实时管理与控制,事后的分析与考评。与已有文献不同的是,本文对该框架的分析深入到了具体的组成部分与运行机制。     

短视频的著作权保护及雷同作品的实质性相似认定

短视频行业承载着庞大流量的同时,也充斥着诸多著作权侵权问题,主要体现在平台上存在大量雷同短视频。鉴于我国目前对雷同短视频的实质性相似并没有统一的认定方法和标准,因此实践中认定短视频实质性相似会有很大难度。本文以近期引发国内外广泛关注的"越南李子柒"事件为视角,从"思想/表达二分法"原则切入,结合国外的相关判例,分析作品实质性相似的几种主要认定方法,最后提出适用于雷同短视频实质性相似的认定方法——"内/外部测试法"。

State-of-the-art of Russia’s heat supply systems

The paper overviews the contemporary state of Russia’s heat supply systems and fuel consumption within its centralized part, the structure of heat consumption by economic sectors and types of industrial consumers. As shown, the centralized heat supply systems, providing the major part of country’s economy with low temperature heat, have heat losses and accident rate at a critical level. The state of decentralized heat supply systems of low rise buildings is not covered by national statistics at all. A second paper on the prospects and development of Russia’s heat supply systems will be published in a subsequent issue.     

城市轨道交通开通运营阶段的溢价回收方法研究

城市轨道交通的外部性导致项目盈利困难,解决这种困难的方案之一是将轨道交通溢价返还给建设企业。然而,作为传统计算溢价大小的方法,地价函数模型缺乏时间序列分析。本文在传统土地溢价计算模型的基础上,引入时间维度,建立城市轨道交通开通运营阶段溢价的面板数据计量模型,使得溢价计算的精度得以提高。
