The Impact of Short-Sales Constraints on Liquidity and the Liquidity–Return Relations

Baker and Stein's (2004) model predicts that individual stock liquidity, commonality in liquidity across stocks, the contemporaneous correlation between stock returns and liquidity, and the degree of high liquidity associated with low subsequent stock returns decrease in the absence of short-sales constraints relative to in the presence. To test these theoretical predictions, we examine both the component stocks of the Taiwan 50 index and other nonindex stocks for the sample period before and after the removal of short-sales constraints on the former and use trading turnover and Amihud's (2002) illiquidity ratio as the measure of liquidity to proxy for investor sentiment. Overall, our empirical results are consistent with these theoretical predictions and therefore provide evidence in support of Baker and Stein's (2004) model.     

Hedging variance options on continuous semimartingales

We find robust model-free hedges and price bounds for options on the realized variance of [the returns on] an underlying price process. Assuming only that the underlying process is a positive continuous semimartingale, we superreplicate and subreplicate variance options and forward-starting variance options, by dynamically trading the underlying asset and statically holding European options. We thereby derive upper and lower bounds on values of variance options, in terms of Europeans.     

资产注入、证券市场监管与绩效

证券市场监管的效率一直是学术界和实务界所关注的问题。由于上市公司的资产注入可划分为经证监会核准的监管型资产注入以及仅通过公司董事会和股东大会批准就可实施的自愿型资产注入,从而为研究证券市场监管效率问题提供了新的契机。本文以2002-2006年五年间上市公司与其控股股东发生的重大资产注入为样本,实证检验了证券市场监管对资产注入绩效的影响。我们的研究发现监管型资产注入对上市公司的绩效产生了正面的影响,而自愿型资产注入对上市公司绩效的影响则并不显著,证券市场监管发挥了相应的效用。

加强非居民税收管理需要引入事实推定规则

本文首先介绍了事实推定规则的含义,然后以案例说明在事实推定规则缺失的情况下非居民税收管理面临的执法窘境,并指出如何引入事实推定规则,最后提出了此规则实施时的限制性规定,以防止基层税务机关滥用本规则侵害纳税人的合法权益。     

中国出口商品增值税税负转嫁的实证研究——基于出口退税政策变化的分析

本文收集了2006年1月至2008年12月期间我国出口商品的价格信息,采用双差法①研究了其中936种出口商品的增值税税负转嫁情况,得出我国出口商品税负前转水平不高,且在各大类商品内部税负转嫁水平也存在较大差异的结论。同时,本文还从出口退税率调整对商品价格影响的视角考量了我国出口商品的供求弹性,并对优化我国出口政策提出了建议。     

Discussion of: “Flattening the organization: the effect of organizational reporting structure on budgeting effectiveness”

This paper is a discussion of Hannan et al. (Rev Account Stud, 2010), wherein subordinate-participants are endowed with private information, and superior-participants can potentially affect budget requests through their ability to reject them. Their findings are of interest to research on both the design of budgeting systems and span of control. I discuss the relevance of HRT to these literatures and comment on their implementation and experimental design. Also, I offer suggestions for future research, one of which is to explicitly introduce monitoring into experiments on span of control.     

当前宏观经济形势与2004年的比较与思考

当前,国内外经济形势错综复杂。文章通过对近期和2004年中国宏观经济形势的比较,分析其中的异同,以厘清未来走势,并为宏观调控提供借鉴。两个时期部有一些相同点：中国经济从低谷走出,乐观情绪升温,房价骤涨,通胀开始抬头,中国跟随世界进人新一轮加息周期,人民币升值压力不断加大。两者不同点是：当前货币增长速度远远快于2004年。贸易顺差更大,信贷和财政状况逊色。未来,预计CPI回升势头更快,央行面临回收流动性的压力更大,贸易摩擦加剧,中美息差可能进一步扩大,人民币的升值压力将加大。
