Size and performance of Chinese mutual funds: The role of economy of scale and liquidity

Using a detailed stockholding for a comprehensive sample of Chinese open-end equity mutual funds from 2004 to the first half of 2010, we investigated the effect of economy of scale and liquidity on the relationship between fund size and performance. We find that an inverted U-shape relationship exists between fund size and performance as measured by various performance benchmarks. Both economy of scale and liquidity play important roles in Chinese mutual funds. Furthermore, their combined effect explains the inverted U-shape relationship of size and performance reasonably well.     

Legal Institutions,Ownership Concentration,and Stock Repurchases Around the World: Signal Mimicking?

One of the central puzzles of signaling theory is how to assess signal quality, in particular the potential for signal mimicking. Our study provides evidence of signal mimicking in the context of stock repurchases. Employing an ex-ante proxy for the likelihood of mimicking stock repurchases and data on open market stock repurchases from 30 countries, we find that long-term operating and market performance following stock repurchases improve less for suspected mimicking firms. This finding contradicts the conventional characterization that managers use stock repurchases to signal undervaluation and enhanced future performance. We find that mimicking firms have smaller capital investments, need greater external financing, buy back fewer shares, and issue more new shares (and/or resell more treasury shares) in the year of the repurchase. Our analysis further shows that mimicking is more likely in countries with weak investor protections and in firms with higher ownership concentration. Further, mimicking associated with concentrated ownership is mitigated in countries with stronger investor protections and by the adoption of International Financial Reporting Standards (IFRS). Altogether, our findings provide evidence of signal mimicking in stock repurchases in international data that is influenced by market, ownership, legal, and financial reporting characteristics of countries.     

The asset growth effect: Insights from international equity markets

Firms with higher asset growth rates subsequently experience lower stock returns in international equity markets, consistent with the U.S. evidence. This negative effect of asset growth on returns is stronger in more developed capital markets and markets where stocks are more efficiently priced, but is unrelated to country characteristics representing limits to arbitrage, investor protection, and accounting quality. The evidence suggests that the cross-sectional relation between asset growth and stock return is more likely due to an optimal investment effect than due to overinvestment, market timing, or other forms of mispricing.     

流域生态补偿中的水资源准市场交易机制研究

建立起市场化水资源配置机制是解决流域水资源短缺和推动流域生态保护的最有效方法.当前,流域水资源商品的准市场化交易模式更符合我国基本国情.为此,本文对流域水资源准市场机制的内涵和机制构建进行了探讨,提出以政府规制为手段构建流域水资源准市场体系,并利用Holmtrom-Milgrom“委托——代理”模型对流域水资源准市场机制进行了建模研究,为构建流域水资源准市场机制提出了政策建议.     

人民币汇率变动对国内消费者价格传导的实证分析

本文首先对汇率传导的理论基础进行了简要阐述,然后通过协整模型、脉冲响应分析和方差分解对人民币汇率的传导效应进行了实证分析.结果表明,人民币汇率对国内消费者价格具有一定的传导效应,长期来看,人民币汇率变动对消费者价格会产生正向影响,且人民币汇率对消费者价格的传导效应明显弱于对进口品价格和企业商品价格的传导效应.     

基于霍太林法则的房地产价格波动分析

许多西方文献研究认为房价从长期看由经济基本面决定,并通过均衡价格理论进行了论证。但本文利用1998～2010年中国房地产季度统计数据分析,发现我国房价与经济基本面缺乏稳定的协整关系;我国房地产价格趋势偏离了局部均衡分析的均衡价格,且房价供求决定方程发生了结构性改变。中国特殊的房地产市场,尤其是受土地政策和心理预期因素影响,很大程度上逼近于一种投机品市场。本文以资源经济学中著名的霍太林法则为基础建立模型,计量分析发现,从阶段特征看心理预期对房价有显著的正向影响;土地供给和房屋租价比、银行利率对房价有显著的负向影响,并提出相应的政策建议。     

我国微型金融可持续发展的战略选择

在深人推进新农村建设和扶贫开发,全面改善农村生产生活条件,加大强农惠农富农政策力度,让广大农民平等参与现代化的进程中,微型金融在大中型农村金融机构逐步退出农村金融市场的背景下,填补了农村金融体系的空白,在解决城乡发展不平衡和农村低收人群体融资难等方面发挥了不可或缺的作用。然而,由于我国微型金融起步比较晚,国内缺乏可借鉴的成功模式,其可持续发展受制于利率市场化程度不高、微型金融法律环境不完善、产品创新不足等因素而缺乏动力。因此,我们应该借鉴国外微型金融持续健康发展的成熟经验,做出我国微型金融可持续发展的科学战略选择。     

Pricing Asian options in a semimartingale model

In this paper we studyy arithmetic Asian options when the underlying stock is driven by special semimartingale processes. We show that the inherently path dependent problem of pricing Asian options can be transformed into a problem without path dependence in the payoff function. We also show that the price is driven by a process with independent increments, Levy processes being a special case. This approach applies for both discretely or continuously options.     

Risk Awareness of Interpersonal Trust and Entrepreneurship in China: Evidence from Survey Data

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.
