现金流量与应计利润在企业债券市场中的有用性——来自沪市的经验证据

文章选取了截止到2005年底在上交所上市的企业债券39支,一共79个公司/年度样本,计算债券年度持有收益率,进而根据面板数据估计了一个横截面回归模型。经验证据表明,债券持有人对会计盈余的两个组成部分都作出正面的估价,并且估价的方式有些类似。这表明会计数字在中国企业债券市场中是有用的,但是应当继续加强发债主体财务信息披露。

Net job creation in the US economy: lessons from monthly data, 1950–2011

This article studies the monthly net job creation (NJC) at the aggregate and the sectoral levels in the United States over the period 1950 to 2011. The article has few important findings. First, NJC did not show a significant trend over the last six decades, which led to a fall in the NJC rate. Second, NJC was very volatile and it could change course even in the span of 1 month. Third, there was no clear pattern about the co-movement between NJC and the change in the unemployment rate. Fourth, the averages of total NJC and private NJC since late 2010 were significantly higher than their respective historical averages and the volatility in NJC since the end of the Great Recession was not unusual by historical standards. Fifth, while the evidence about the effects of the 2009 American Recovery and Reinvestment Act on employment is inconclusive, some sectors appeared to benefit from it. Finally, the most frequent drop in the unemployment rate was by 0.1%, and drops of more than 0.2% should not be highly expected.     

Use of a diagnosis-based risk adjustment model to estimate costs of indigent care in a community at Medicaid reimbursement rates

Objectives: This study used a diagnosis-based risk adjustment model to estimate the annual costs of uninsured patients in Austin, Texas, and describe the prevalence and costs of their chronic conditions. The data were supplied by the Indigent Care Collaboration, a partnership of local safety-net hospitals and clinics.

Methods: This study used the Diagnostic Cost Groups prospective Medicaid All-Encounters model, which uses diagnoses, age and gender to assign relative risk scores to patients. The relative risk scores were multiplied by the per capita Texas Medicaid expenditure to obtain estimated annual costs. Chronic diseases were described in terms of prevalence and total estimated annual cost.

Results: A total of 471,194 encounters were recorded for 163,729 patients meeting the study inclusion criteria between the 1st March 2004 and the 28th February 2005. The mean estimated patient yearly cost was US $1,307, and the total estimated yearly population cost was $228,909,529. The most common chronic conditions included hypertension, diabetes, depression, substance abuse, pregnancy, asthma, chronic obstructive pulmonary disease and congestive heart failure.

Conclusions: This study demonstrates how the unknown costs associated with caring for indigent uninsured patients in a community can be estimated at Medicaid reimbursement rates using the Diagnostic Cost Group model on aggregated patient encounter data.     

通货膨胀冲击的财产再分配效应——基于中美两国的比较研究

本文利用微观调查数据研究了中美两国通胀冲击的财产再分配效应。本文的定量研究结果表明,通胀冲击将侵蚀中国家庭部门的财产,并进一步恶化家庭间的财产分布;而美国的情况却截然相反。从通胀再分配效应的视角出发,本文建议我国在制定货币政策时应当更加重视民生目标,逐步建立起多种形式的通胀补贴制度,以增强社会底层的通胀承受能力。
