利率互换与我国商业银行利率风险管理

随着我国金融改革的深化,金融市场的不断开放,市场化利率逐渐形成,利率风险越来越受到金融机构从业者的关注。在我国开展利率互换交易的条件基本成熟的情况下,引入的利率互换为我国商业银行的利率风险管理展开了新的一页。由于仍存在阻碍利率互换交易发展的定价、风险、制度及供需问题,所以需要从加快利率市场化;加快相关制度建设;加快市场培育,增加参与主体;完善信用风险防范等方面来推进商业银行的利率风险管理。     

PUBLIC CHOICE THEORY AND HOUSE OF LORDS REFORM

By revealing the propensity of elected governments to indulge in self‐interest at the expense of the people's liberty, public choice theory provides powerful arguments in favour of an appointed House of Lords rather than an elected upper chamber.     

Star rating and corporate affiliation: their influence on room price and performance of hotels in Israel

The purpose of this paper is to ascertain whether and how star rating and corporate affiliation, as signals of quality, influence pricing decisions of hotels in Israel in various geographical locations, each with its specific market characteristics and during two different periods in which the business environment suffers from a crisis due to the political circumstances in the Middle East. The data suggests that the star-rating system, which is traditionally used to rate hotels’ quality, is a still stable and consistent predictor of room prices. However, in light of the increased usage of brand names in the Israeli industry, it was found that the ability to charge and receive a premium for the hotel corporate affiliation or brand name is not consistent. The analysis presents the case in which a premium for brand name is eroded by the influence of the crisis, by the level of corporate intensity in the region, and also by the relative strength of consumers in the different geographical locations.     

从房价上涨看中央政府与地方政府的博弈

近年来我国房价持续上涨,国家颁布一系列相关措施,但调控效果却并不显著。原因在于,分税制下中央政府与地方政府之间存在利益的冲突。地方政府关注的是房地产发展对地方经济效益的贡献,而非国民经济的均衡发展。地方政府的消极支持,使得房价有增无减。     

Portfolio efficiency of a dynamic capital asset pricing model

In the present study we show that, based on equally weighted portfolios of continuously listed Finnish and Swedish stocks, aDynamic Model of Capital Asset Pricing (DCAPM) outperforms the static Capital Asset Pricing Model (CAPM) in the Super Criterion Test. It is demonstrated that the portfolio efficiency of the dynamic model is improved, when using a properly defined transition matrix in the Kalman Filtering Algorithm.The advice and encouragement of Professor Leif Nordberg (Department of Statistics, Åbo Akademi University) is gratefully acknowledged. I thank Jaana Aaltonen for her assistance in monitoring the computer programs. I also thank an anonymous referee for his valuable comments and suggestions for improving the quality of the paper.     

The dark side of financial innovation: A case study of the pricing of a retail financial product

The offering prices of 64 issues of a popular retail structured equity product were, on average, almost 8% greater than estimates of the products' fair market values obtained using option pricing methods. Under reasonable assumptions about the underlying stocks' expected returns, the mean expected return estimate on the structured products is slightly below zero. The products do not provide tax, liquidity, or other benefits, and it is difficult to rationalize their purchase by informed rational investors. Our findings are, however, consistent with the recent hypothesis that issuing firms might shroud some aspects of innovative securities or introduce complexity to exploit uninformed investors.     

经济全球化背景下国家矿产资源安全研究——基于自由贸易理论及我国当前贸易结构和贸易形势的考量

矿产资源贸易出于需求,而表现为价格差异导致.伴随经济全球化过程,掩盖在自由贸易体制下世界各主要工业国对矿产资源的争夺,是矿产资源在世界范围内配置的实质.获得商品定价权是取得矿产资源贸易有利地位的关键,从而提高本国矿产资源的安全程度.本文基于自由贸易理论,结合我国当前的贸易结构和贸易形势,研究我国矿产资源安全的现状,进而对确保矿产资源安全提出相应的对策建议.     

A Note: Natural Generalization of Black-Scholes in the Presence of Skewness,Using Stable Processes

The Lognormal price model is generalized to the class of Log-Stable Processes, a family which possesses self-similarity properties usually only associated with the Lognormal, but which, more generally, can model negatively skewed distributions of return. This generalization appears to explain several discrepancies between the Black-Scholes Model and observed market phenomena, such as the variation of implied volatility of option price with exercise price and term to expiry, and the nonzero probability of bankruptcy or ‘crash’. It will be argued that the class of maximally negatively skewed Stable distributions (a class which, paradoxically, contains the normal) may be utilized to produce models which imply these phenomena naturally.
