The Investment Performance of Art in Mainland China

This article investigates price determinants and investment performance for paintings from mainland China using hedonic regression analysis applied to a new dataset from over 190,000 auction transactions. The price index obtained indicates that from 2000 to 2015, the average annual appreciation in value of Chinese art was 8.42% in real USD. Compared with American artwork, global artwork, and traditional financial assets, Chinese art possesses a comparatively better risk and return profile and a low correlation with other assets. Finally, regarding the masterpiece effect, the conclusion is that highly priced Chinese art does not underperform the market.     

基于声誉效应的工程监理激励机制模型研究

为了提高工程监理工作积极性,基于Holmstrom-Milgrom模型,引入声誉效应,建立声誉效应和显性激励机制相结合的动态委托代理激励模型。分析声誉效应发挥激励机制作用条件,并与未考虑声誉效应的委托代理模型进行比较。结果表明:声誉效应在满足一定的条件下,引入声誉激励机制能够增加业主的期望收益,并且能提高监理的努力水平。最后,通过数值仿真模拟验证引入声誉效应的合理性。     

Order book approach to price impact

Buying and selling stocks causes price changes, which are described by the price impact function. To explain the shape of this function, we study the Island ECN orderbook. In addition to transaction data, the orderbook contains information about potential supply and demand for a stock. The virtual price impact calculated from this information is four times stronger than the actual one and explains it only partially. However, we find a strong anticorrelation between price changes and order flow, which strongly reduces the virtual price impact and provides for an explanation of the empirical price impact function.     

The Expiration Effects of Stock-Index Derivatives: Empirical Evidence from the Taiwan Futures Exchange

Five index derivatives with the same expiration days, settlement days, and settlement systems have been consecutively traded on the Taiwan Futures Exchange (TAIFEX) since 1998. This paper examines the expiration effects of TAIFEX index derivatives on the underlying stock market between 1998 and 2002. Our empirical findings show no significant expiration effects on the expiration day, but evidence demonstrates that expiration effects have strengthened as more relative index derivatives are listed on the TAIFEX. Meanwhile, the expiration effects seem to shift to the opening of the settlement day. In general, the expiration effects in Taiwan are not as significant as those in U.S. markets but are stronger than those in the Hong Kong market. The special settlement procedures adopted by the TAIFEX may account for the difference.     

外商直接投资的产业技术溢出效应对比研究——基于35个产业面板数据的实证分析

结合中国的产业特性,使用1999～2010年35个产业的面板数据,在采用两种度量指标衡量外商直接投资(FDI)的不同溢出途径的基础上,考量外商直接投资对内资企业的横向溢出效应与后向链接效应,并且检验了产业间的异质性。结论表明,我国的外商直接投资存在着显著为正的后向溢出效应,也存在一定程度的横向溢出效应,外资企业的人员流出能显著促进同一产业内内资企业的生产效率提高;劳动密集型产业与资本技术密集型产业的横向溢出效应与后向链接效应存在一定差异。     

投资者情绪对我国股市行业收益率的动态影响作用——基于固定效应广义最小二乘法的研究

本文使用2005--2011年我国股市行业收益率数据并构造投资者情绪指标,利用VAR格兰杰因果检验和固定效应广义最小二乘法分析投资者情绪对我国股市的动态影响。实证结果发现,2005--2011年的两次股票市场大幅度涨跌中,我国投资者情绪和股票收益率存在双向因果关系;投资者情绪在3个月内会对股票收益率有正面的影响,此后12个月内其正向影响作用出现了明显的负向反转,其中具有较高账面市值比和占有较高经济地位的交通运输业、信息技术业和制造业等国家基础行业容易受到投资者乐观情绪的影响而出现大幅度涨跌。     

Impact of contracts in high yielding varieties seed production on profits and yield: The case of Nepal

Nepal’s population continues to grow, but the agricultural sector’s performance remains almost stagnant. This has led to a decline in the per capita availability of food. Increasing agricultural productivity is the key to agricultural growth, and one strategy for increasing agricultural productivity is to use improved seeds. This study investigates the impact of contract farming (CF) in high yielding varieties (HYV) of paddy seed production on costs, yield, and profits of smallholder farms in Nepal. Using farm-level data and a non-parametric propensity score matching estimator, the study finds a significant positive impact of contract HYV seed farming on revenues, profits, and yield, and a significant negative impact on total costs of production. Additionally, very small farms (⩽0.43 ha) with CF in HYV paddy seeds tend to gain the most when it comes to yield per hectare. Our estimates reveal that the average smallholder household in Nepal engaged in CF with input conditions receives higher profits. However, farmers engaged in CF with output conditions tend to have higher yields but smaller profits. Finally, farmers engaged in CF in HYV paddy seeds with both input and output conditions have the highest yield gains and significantly higher profits.     

人民币汇率波动背景下的“钟摆效应”探析

2012年以来,人民币对美元汇率继续呈现双向波动趋势,升值和贬值预期交替出现。企业等市场主体根据人民币汇率预期变动,灵活调整外币资产负债配置结构,使财务运作呈现较为明显的“钟摆效应”。“钟摆效应”的出现,反映了国内市场主体对汇率风险意识的增强,也影响到外汇资产在央行和市场主体间配置的变动,增加跨境资金流动的波动性。为更好地适应国内市场主体外币资产配置需求的变化,文章提出相关政策建议。     

Calendar effects and the pricing of risk: the UK evidence

For some time there has been a puzzle surrounding the seasonal behaviour of stock returns. This paper demonstrates that there is an asymmetric relationship between risk and return across the different months of the year. The paper finds that systematic risk is only priced during the months of January, April and July. Variance risk and firm size are priced during several months of the year including January. An analysis of the relative behaviour of size based securities reveals that firm capitalization makes a valuable contribution to the magnitude of risk premiums.
