The demand for accounting information: young NASDAQ listings versus S&P 500 NYSE listings

The main purpose of this paper is to examine accounting information which can be of poor quality for some industries because uniform regulation applies to all. However, there is a strong demand for reliable accounting data even when the quality of the data is poor. Consistent with this premise, I show that among young NASDAQ listings the valuation coefficient on BVE is higher and that on earnings is not lower for intangible-intensive ventures than for other firms. I also show that GAAP OCF provides additional information that enhances the quality of earning information. This results in a shift in valuation weight from BVE to earnings for intangible-intensive young NASDAQ listings. However, these phenomena do not appear for intangible-intensive S&P 500 firms listed on NYSE. My results suggest that variations in the demand for reliable financial data affect the valuation coefficients on earnings and BVE.     

AN INDUSTRIOUS REVOLUTION IN AN EAST ASIAN MARKET ECONOMY? TOKUGAWA JAPAN AND IMPLICATIONS FOR THE GREAT DIVERGENCE

This paper addresses a question raised by Jan de Vries' on the relationship between industriousness and the rise of the market in East Asia. Was the growing industriousness in Tokugawa Japan, as de Vries suggests, a substitute ‘for the absence of markets’? The examination refers to two versions of Chayanov's peasant farm model and their empirical relevance to the Tokugawa agrarian history, with special reference to the formation of labour‐intensive peasant farming (Akira Hayami's version of an industrious revolution), product specialisation, and the markets for production factors, land, and labour. Its implications for the Great Divergence debate are also discussed.     

A case-control comparison of direct healthcare-provider medical costs of chronic idiopathic constipation and irritable bowel syndrome with constipation in a community-based cohort

Objective: Patients with constipation account for 3.1 million US physician visits a year, but care costs for patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) compared to the general public have received little study. The study aim was to describe healthcare utilization and compare medical costs for patients with IBS-C or CIC vs matched controls from a community-based sample.

Methods: A nested case-control sample (IBS-C and CIC cases) and matched controls (1:2) for each case group were selected from Olmsted County, MN, individuals responding to a community-based survey of gastrointestinal symptoms (2008) who received healthcare from a participating Rochester Epidemiology Project (REP) provider. Using REP healthcare utilization data, unadjusted and adjusted standardized costs were compared for the 2- and 10-year periods prior to the survey for 115 IBS-C patients and 230 controls and 365 CIC patients and 730 controls. Two time periods were chosen as these conditions are episodic, but long-term.

Results: Outpatient costs for IBS-C ($6,800) and CIC ($6,284) patients over a 2-year period prior to the survey were significantly higher than controls ($4,242 and $5,254, respectively) after adjusting for co-morbidities, age, and sex. IBS-C outpatient costs ($25,448) and emergency room costs ($6,892) were significantly higher than controls ($21,024 and $3,962, respectively) for the 10-year period prior. Unadjusted data analyses of cases compared to controls demonstrated significantly higher imaging costs for IBS-C cases and procedure costs for CIC cases over the 10-year period.

Limitations: Data were collected from a random community sample primarily receiving care from a limited number of providers in that area.

Conclusions: Patients with IBS-C and CIC had significantly higher outpatient costs for the 2-year period compared with controls. IBS-C patients also had higher ER costs than the general population.     

On the long-term or short-term dependence in stock prices: Evidence from international stock markets

This study examines the short- and long-term dependence in the United States and 21 international equity market indexes. Two heteroscedastic-robust testing methods, the modified rescaled range analysis and the rescaled variance ratio test, are employed to test for the existence of dependence. The evidence consistently reveals the absence of long-term dependence in these 22 stock returns indexes. The random walk hypothesis for most, but not all, stock returns indexes is not rejected. When the random walk hypothesis is rejected, the evidence supporting the rejection is weak and the stochastic dependence occurs mainly in short-horizon, rather then long-horizon holding period returns.     

城市建成环境对鸟类多样性的影响 机制研究评述及展望

城市化带来的环境变化是生物多样性的主要威胁， 但城市同样也是生物多样性保护的热点地区。因此，分析和预 测城市环境变化对生物多样性的影响对于维护城市生态系统服 务，提升人类福祉至关重要。目前，越来越多的研究对城市建 成环境进行了详细的分类，分别量化了各个城市特征对生物多 样性水平的影响。然而，对影响城市内生物多样性水平的因 素仍缺乏多尺度、全球性的分析。借助Web of Science和 CNKI，对来自全球37个城市的111篇文献进行了建成环境下 鸟类多样性研究方法和结果的系统性分析，并在归纳关键性城 市建成环境要素的基础上，提出了以生物多样性为导向的建成 环境优化策略，指出了鸟类多样性保护和城市可持续发展的未 来方向。     

Do bank managers signal through cash flow statements?

We empirically examine the cash flow statements for Japanese banks and whether their managers engage in classification shifting to temper concerns about risk exposure. To create a buffer against liquidity shocks, they shift cash flows from investing and/or financing activities to operating activities. We also find robust evidence that classification shifting intensifies in higher risk situations. Although prior research on managerial discretion focuses on earning management, we are the first to show cash flow management to avoid sequential negative changes in operating cash flows. We show that these activities convey valuable information about changes in banks' risk exposure.
