A Note on Affordability and the Optimal Share Price

Despite the increase in institutional ownership, decreased trading costs, and increased real personal savings, we find that the average stock price is lower today than it was in the 1920s. In the aggregate, the propensity to split is a function of recent market performance, personal savings, and the desirability of appearing to be a small firm. Our results indicate that, after decades of inflation and the average stock price falling, splitting stocks to return to an affordable trading range must be rejected as an explanation. This suggests that other economic forces are behind splits, whether traditional or behavioral in nature.     

货币政策应该关注资产价格和汇率吗?

在Rudebusch and Svensson(1999)模型中引入了房地产价格、股票价格和汇率因素,以此为基础推导出最优货币政策反应函数。该反应函数显示,中央银行既要应对产出和通货膨胀变化,还应该考虑资产价格和汇率波动。基于GMM方法的实证分析表明,该反应函数能够较好刻画过去10多年间中国中央银行的货币政策。总体而言,该反应函数可以作为中国货币政策制定和执行的参考框架,货币政策应该对资产价格和汇率波动给予一定程度的关注。     

Anonymity,Stealth Trading,and the Information Content of Broker Identity

This paper examines whether the identity of a broker involved in transactions contains information. Using a sample of transactions from the Australian Stock Exchange—where broker identity is transparent—we provide evidence that consecutive buyer‐/seller‐initiated transactions by the same broker have a relatively high permanent price impact. This implies that broker identity conveys information to market participants, and that markets in which broker identity is disclosed are likely to be more efficient. We also find that medium‐sized trades by the same broker convey greater information than large and small trades, which is consistent with stealth trading by informed investors.     

Reconsidering the Relationship between Inflation and Relative Price Variability

It has long been popularly believed that the relationship between inflation and relative price variability (RPV) is positive and stable. Using disaggregated CPI data for the United States and Japan, however, this study finds that the relationship is neither linear nor stable over time. The overall relationship is approximately U‐shaped around a nonzero threshold inflation rate. RPV therefore changes not with the inflation rate per se, but with the deviation of inflation from the threshold inflation rate. More importantly, the relationship is by no means stable over time but instead varies significantly in a way that coincides with regime changes of inflation or monetary policy. The relationship was positive during the period of high inflation of the 1970s and the early 1980s, as has been documented by a number of previous studies, whereas it takes a U‐shape profile during the Great Moderation. The results are robust to the use of core inflation, which excludes the traditionally volatile prices of food and energy. This paper then presents a modified version of the Calvo‐type sticky price model to describe the observed empirical regularities. Simulation experiments show that the modified Calvo model fits the data well, and that the underlying relationship hinges upon the degree of price rigidity, which is systematically related to inflation regime. For countries and periods with low inflation rates, the relationship takes a U‐shape as price adjustment is more sticky. In a high‐inflation environment, when price setting becomes more flexible, the U‐shaped profile vanishes.     

中国再生资源价格长期波动特征及其对经济的影响研究

尽管再生资源在工业生产中替代原生资源的比例逐渐升高,但对再生资源价格波动的特征及对经济的影响尚缺乏研究。本文以再生铜为例,采用GRACH族模型分析发现,我国再生铜价格的波动存在一定集聚性和持续性,价格波动比较缓慢。且负向冲击对再生铜价格波动的影响比正向冲击大,存在显著的杠杆效应。此外,再生铜价波动具有显著的GARCH-M效应,即预期的风险对再生铜价格波动具有正向影响。然后采用VAR模型和脉冲响应函数等方法,引入产出、投资、消费和通货膨胀率变动等宏观经济变量,定量分析了再生资源价格波动与中国经济之间的关系。检验结果表明：再生铜价作为建筑业重要的生产资料,其价格上涨短期内 促使GDP增长,但长期则抑制投资,最终可能影响GDP增长并提高通货膨胀率,即再生铜价格上涨对国家经济发展有不利影响。本文的实证结果揭示出,对中国经济的影响而言,废旧金属价格的变动只是某种表象,经济增长和通货膨胀率变动的背后是更为复杂的原因,问题的实质是以固定投资拉动经济增长的发展模式和部分地区对房地产业过度依赖的产业结构的变化等对中国经济产生的根本性的影响。

会计价值机制论

本文认为,市场和企业是组织经济活动的形式,也是组织价值信息传递和价值激励的系统。市场价格机制是在长期市场供求关系作用下而形成的,而会计价值机制是随着企业的发展不断演化,在企业目标引导下组织价值信息传递和价值信息激励,以促成企业目标实现。企业替代市场或取得竞争优势,都是基于相同的原因和两种机制作用的结果,即是通过企业提供的产品或服务的成本低于市场价格而实现的。

企业推广排污权交易的可行性研究

排污权交易(Ernission trading)是一种基于市场(Market-based)的环境政策。本文坚持以科学的发展观，来研究经济发展与环境保护的协调关系，目的是实现环境资源和环境容量的可持续利用。本文分析了企业的排污行为决策，并将环境资源和环境容量的稀缺性纳入排污权交易价格之中。通过价格这个经济杠杆去调节人们对环境资源和环境容量的利用，反映于企业为其排污行为所作的选择，进而论述企业推进排污权交易的可行性。
