社会互动与家庭金融资产配置

运用中国家庭金融调查(CHFS)数据,研究社会互动与家庭金融资产配置之间的关系.研究发现,适当增强社会互动会促进家庭更多地参与风险金融市场,增加投资风险资产的比例,提高金融资产的分散化程度,优化资产的配置效率.但当社会互动达到一定程度后,过度的社会互动则会抑制家庭参与风险市场,减少风险资产的投资比重,降低金融资产的分散...     

中国银行间外汇市场的套利机会

对于人民币远期汇率是否满足利率平价,目前国内理论界与实务界还存在一定的分歧。本文任意选取2009年6月1～30日中国银行间外汇市场美元/人民币汇率连续实时的买卖报价等数据,首次对该市场的套利机会进行了测度。研究发现:(1)从抵补套利角度看,国内银行间中短期限(1年以内)的远期汇率定价符合利率平价理论;但因定价基准利率(SHIBOR)未能充分发挥基础利率的功能,致使1年期左右的人民币远期汇率存在潜在抵补套利机会,然而其收益率很低。(2)银行间外汇市场几乎随时都存在收益率可观的单边套利机会。(3)银行有足够的时间进行套利交易。     

境外上市与企业投资效率

截至2021年11月,我国单独境外上市企业占到境外上市企业总数的88.32%,但单独境外上市的研究明显与该数据不匹配,研究数量缺乏。为扩充该方面研究,本文以2012~2020年单独在美国和中国香港上市的中资企业为研究对象,对境外上市与投资效率关系进行检验。实证结果发现,单独境外上市与境内上市企业相比投资效率更低,区分企业上市地点后发现,规模大、信息透明度低、存在代理成本的赴港上市企业比境内上市企业投资效率低,规模小、代理成本高、信息透明度低的赴美上市企业比境内上市企业投资效率低。通过机制分析发现,信息透明度、境外上市和非效率投资三者存在\"遮掩效应\",境外上市企业未能受到有效的信息约束。     

An analysis of the profitability of businesses of diversified companies

This paper presents empirical evidence on the relationship between diversification and profitability. The data set used in the analysis includes data on 55 U.S. corporations who participated in phase II of the project on Profit Impact of Market Strategy (PIMS).Following upon the pioneering work of Carl Kaysen, complex indices of diversification are developed. Cross sectional regression analyses indicate a statistically significant positive association between measures of corporate diversification and measures of business profitability (return on investment or profit margin on sales). These relationships are insensitive to variations in the treatment of outliers, and do not appear to be accounting artifacts.

Does distance matter for internationally-oriented small firms?

This paper assesses the contemporary relevance of distance and its key components in international business for young, internationally-oriented small firms. In doing so, it reconceptualizes the distance concept and investigates its relevance in American, British, and German firms' early foreign market selection. Economic, geographic, and cultural distance (based on Hofstede's and Schwartz's frameworks) for the three countries, along with psychic distance for the German firms, are considered. The results show that some components of distance still matter for internationally-oriented small firms and that cultural distance is sample source and concept sensitive. In addition, psychic distance acts as a mediator construct to the more objective, external distance measures of economic, geographic, and cultural distance, confirming the proposed distance framework.
