What Prompts the People＇s Bank of China to Change Its Monetary Policy Stance？ Evidence from a Discrete Choice Model

In the present paper, we model the policy stance of the People＇s Bank of China （PBC） as a latent variable, and the discrete changes in the reserve requirement ratio, policy interest rates, and the scale of open market operations are taken as signals of movement of this latent variable. We run a discrete choice regression that relates these observed indicators of policy stance to major trends of macroeconomic and financial developments, which are represented by common factors extracted from a large number of variables. The predicted value of the estimated model can then be interpreted as the implicit policy stance of the PBC. In a second step, we estimate how much of the variation in the PBC＇ s implicit stance can be explained by measures of its policy objectives on inflation, growth and financial stability. We find that deviations of CPI inflation from an implicit target and deviations of broad money growth from the announced targets, but not output gaps, figure significantly in the PBC＇s policy changes.

西部大开发中的生态旅游业发展

2000年中国政府实施了西部大开发战略，几平所有西部省、市、区都将旅游产业作为支柱产业发展，奠中大部分地区为实现“双赢”提出发展生态旅游业。因此，生态旅游资源的开发已成为推动西部地区经济发展的一项重大政策和支柱性产业。     

试论市场经济条件下的经济计划

在商品货币关系广泛存在的情况下,要想恰当有效地按比例分配社会劳动时间,既离不开市场的作用,也离不开计划的作用。这既为资本主义社会的实践所证明,也为社会主义社会的实践所证明。对这个问题进行深层次的分析,可以从生产关系与生产力、上层建筑与经济基础的关系上,从计划与市场的内在统一性上。从计划与市场两种手段的不同特点上找到理论根据。在市场经济条件下,并不排斥计划的作用,但计划工作必须进行改革使之与发展市场经济相适应。     

论企业的品牌战略——以商标法为视角

在世界经济一体化进程中,我国企业知名品牌数量少、档次低,影响其发展壮大,促使其树立品牌战略。从商标法的角度看,品牌设计要符合法律的规定,考虑到不同地区的风俗习惯,尽量使用强商标。商标要及时注册和续展,使用联合商标和防御商标,以防止商标被境外抢注;同时,也要注重商标管理和保护,保证企业的品牌战略顺利实施。     

Pricing options using implied trees: Evidence from FTSE‐100 options

Previously, few, if any, comparative tests of performance of Jackwerth's ( 1997 ) generalized binomial tree (GBT) and Derman and Kani ( 1994 ) implied volatility tree (IVT) models were done. In this paper, we propose five different weight functions in GBT and test them empirically compared to both the Black‐Scholes model and IVT. We use the daily settlement prices of FTSE‐100 index options from January to November 1999. With both American and European options traded on the FTSE‐100 index, we construct both GBT and IVT from European options and examine their performance in both the hedging of European option and the pricing of its American counterpart. IVT is found to produce least hedging errors and best results for American call options with earlier maturity than the maturity span of the implied trees. GBT appears to produce better results for American ATM put pricing for any maturity, and better in‐sample fit for options with maturity equal to the maturity span of the implied trees. Deltas calculated from IVT are consistently lower (higher) than Black‐Scholes deltas for both European and American calls (puts) in absolute term. The reverse holds true for GBT deltas. These empirical findings about the relative performance of GBT, IVT, and Standard Black‐Scholes models are important to practitioners as they indicate that different methods should be used for different applications, and some cautions should be exercised. © 2002 Wiley Periodicals, Inc.

黑天的故事——“文革”时代的地下手抄本

“文革”手抄本中讲述的这些故事,不过是中国革命这一台大戏的细碎片段而已。也正因为这样,我们才可以借助于它们而管窥到,那场炽烈的革命是怎样走向了自己的反面。以往这些手抄本之所以受到轻视,主要是因其太过原始和低俗,不过正如本文所证明的, 其实恰恰鉴于这种出奇的原始和低俗,反而更值得好好琢磨一番。说穿了,这些已被兀鹰啄食干净的文明骷髅,竟是在无情地警示着,经过那场彻底的浩劫,一切都只有无所遮蔽地重新开始了,再没有什么理由去讲什么“文明古国”之类的大话了。
