Trading volume and stock market volatility: The Polish case

Relying on the mixture of distributions hypothesis (MDH), this paper investigates the relationship between daily returns and trading volume for 20 Polish stocks. Our empirical results show that in the majority of cases volatility persistence tends to disappear when trading volume is included in the conditional variance equation, which is in agreement with the findings of studies on developed stock markets. However, we cannot confirm the testable implications of the MDH in all cases, which indicates that future research on the causes and modeling of Polish stock market volatility is necessary.     

冀东港口经济贡献的实证研究

港口是推动国际贸易发展的重要基础设施,也是间接推动区域乃至国家经济发展的重要条件,鹿特丹港、纽约港、东京港等国际大港在推动各自国家崛起中的重要作用都充分说明了这一点。河北省是我国环渤海经济圈的重要成员,秦皇岛港、唐山港、黄骅港都是环渤海港口群的重要组成部分,如何建设和利用这些冀东港口推动区域经济又好又快发展成为亟待研究的课题。

How do firms finance their exports? – evidence from China

Using a firm-level production data over the period of 2005–2009 from China, this paper provides a new empirical evidence on how firms finance their exports when they have several financial options. The main results of the paper can be summarized as follows. First, firms who have better access to any finance are more likely to export and export more. More financial options lead to a higher export probability and capacity due to the complementary relation between financial options. Second, of all financial options, the internal finance captured by cash holdings or profit plays the most important role on firms’ export likelihood and volume. Firms rely more on the external finance through borrowing to start exporting, but depend more on issuing stocks to their shareholders to expand their exports. Third, subsample results suggest that the financial option of issuing stocks is generally more important for firms who have worse access to external finance in determining export propensity and quantity, such as private-owned firms, small-scale firms, young firms, and non-eastern firms.     

中国贸易强国之路——自主创新

2004年中国的进出口贸易总额高达11547．4亿美元,超过日本一跃成为世界第三贸易大国。对外贸易额平均每年以超过15％的速度增长。2007年中国进出口总额更是达到了21728亿美元,比上年增长23．5％,跃居世界第二位。但是我国贸易大国地位却蕴藏着脆弱的基础,例如出口商品结构不合理,产品竞争力不强;服务贸易发展滞后,比重偏低;出口商品缺乏具有自主知识产权的知名品牌和核心技术等等。我国是贸易大国的同时又是贸易弱国。我国提出要在2020年以前发展成为世界贸易强国的目标。文章提出了中国贸易强国之路,即自主创新。

中国碳试点市场集中交易行为的理论研究

通过构建一个代表性控排企业跨期决策理论模型,分析碳配额交易企业在履约日与非履约日的最优交易量。均衡结果显示,企业在非履约日的最优交易量与其自身的风险规避系数、市场流动性提供者的风险规避系数、履约日随机碳需求的标准差成正比,而与企业的碳产出效率成反比。在此基础上,探讨了中国碳交易试点市场上履约日附近交易量巨大,而非履约日交易量稀少的原因,并提出相关政策建议,以帮助实现我国碳市场交易量的平滑及整体市场效率的提升。     

Visual Effects of Variety and Area Saliency on Food Product Volume Estimates

This paper aims to assess the combined effects of variety and area saliency on consumer estimates of product volume. In the first of two studies, we examine the effect of color variety on perceived quantity estimates of cereal in a bowl. In addition, this study was designed to determine if the saliency of the area occupied by the cereal in the bowl moderates any effect of color variety. The second study utilizes a matching task to determine if product variety and area saliency cause consumers to pour more cereal into bowls due to perceptual errors in volume estimation. Findings reveal that consumers use visual cues of area saliency first when approximating quantity. When area saliency cues are removed, consumers base quantity approximations on visual cues provided by product variety. This suggests that container design plays an important role in perceived quantity expectations by moderating the influence of perceived variety.
