The pricing of common exchange rate factors in the U.S. equity market

We extend Lustig et al. (Rev Financ Stud 24:3731–3777, 2011) and Brusa et al. (The International CAPM Redux, 2014) by examining if the common exchange rate factors, the dollar and carry factors, are priced in the US equity market. Our results suggest that while the carry factor has incremental pricing information relative to the US market factor, the dollar factor (or the trade-weighted exchange rate index) is redundant. Our results have important theoretical as well as practical implications. Theoretically, we suggest that financial economists take an endogenous perspective of exchange rates. Practically, we suggest that practitioners incorporate in the carry factor to measure the exposure of exchange rate risk.     

How Do Institutional Investors Affect Corporate Performance? Evidence from Private Placements in China

Using data on private placements in China from 2007 to 2014, we show that abnormal returns of issuing companies’ stocks are significantly positive on the announcement day, but they become significantly negative during the event window [?20, +20]. Participation by institutional investors has a significant and negative impact on the short-term stock returns. This negative effect is also present in issuing companies’ long-term stock returns and profitability. Furthermore, we find that participation by institutional investors reduces dividend payments after private placements. Overall, our findings do not support the monitoring hypothesis of institutional investors’ role in corporate finance but are consistent with the management entrenchment hypothesis and shareholder pessimism hypothesis.     

精准扶贫背景下农村资金投入与农民收入增长研究

本文采用时间序列数据对财政支农支出与农民收入之间的关系进行了实证研究。 结果显示财政支农资金对农村居民收入产生了显著的正面影响;财政支农结构中,支援农业生 产支出对农民收入的影响最大,然后依次是农业基本建设支出和农村救济费,而农业科技三项 费用对农民收入的影响不显著。综合考虑财政对三农、教育、健康的投入的研究结果显示,国 家在健康方面的投入对农村居民纯收入的正面影响最大,其次是对“三农”的支出,农村居民 的受教育水平对农村居民的纯收入的影响为负,但对农村居民的经营性纯收入和工资性纯收入 的影响为正。在此基础上,结合国家精准扶贫背景,本文建议应继续加大财政对“三农”的支 持力度,同时重视对农村健康和教育方面的投资,在健康与教育之间,应该优先选择提升农村 居民的健康水平。     

中小企业融资难的新解读

中小企业融资难问题已成为制约我国市场经济体制改革的重要因素。对主要发达国家经验的梳理,可以得到解决该问题的一般规律。基于我国中小企业发展的特点、金融系统结构失衡、政府职能错位三个方面的解读,可以发现我国中小企业融资难问题具有特殊性。本文提出的建议,包括构建"银政合作"模式,推进金融体制改革,创建中小型金融机构。     

考虑干扰风险影响下应急物流仓储量最优模型分析

传统模型在处理应急物流仓储量时,存在抗风险弱、误差大的缺陷,容易出现混乱,无法进行有效的调度,不能满足及时的应急物流需求。为了解决这一问题,提出一种考虑干扰风险影响下的应急物流仓储量最优模型,模型使用仓储量方案优化指标体系层次结构,分析不同的干扰风险因素,获取最佳的仓储量控制方案,通过立体物流仓储模型获取仓储货位的有效货物量,采用微粒子优化算法对立体物流仓储模型进行优化求解,获取最佳的仓储量。仿真实验结果表明,该模型能够准确描述不同的干扰风险,具有较高的仓储量优化效率和较低的误差率。     

The 52-week high momentum strategy in international stock markets

We study the 52-week high momentum strategy in international stock markets proposed by George and Hwang [George, T., Hwang, C.Y., 2004. The 52-week high and momentum investing. Journal of Finance 59, 2145-2176.]. This strategy produces profits in 18 of the 20 markets studied, and the profits are significant in 10 markets. The 52-week high momentum profits exist independently from the Jegadeesh and Titman [Jegadeesh, N., Titman, S., 1993. Returns to buying winners and selling losers: implications for market efficiency. Journal of Finance 48, 65-91.] individual stock and Moskowitz and Grinblatt [Moskowitz, T.J., Grinblatt, M., 1999. Do industries explain momentum? Journal of Finance 54, 1249-1290] industry momentum strategies. These profits do not show reversals in the long run. We find that the 52-week high is a better predictor of future returns than macroeconomic risk factors or the acquisition price. The individualism index, a proxy to the level of overconfidence, has no explanatory power to the variations of the 52-week high momentum profits across different markets. However, the profits are no longer significant in most markets once transaction costs are taken into account.     

An investigation of restaurant food safety performance: A comparison between ethnic and nonethnic and chain and independent restaurants in Louisiana

This study examines health inspection data from casual dining restaurants and compares differences of food code violations between ethnic and nonethnic restaurants. A total of 7,415 violations were retrieved from the restaurant inspection reports of 769 restaurants. Ethnic restaurants have more violations than nonethnic restaurant in categories related to food time/temperature violations, cross contamination, and food condition/surface/labels. Nonethnic and chain restaurants had fewer behavioral violations than ethnic and independently operated restaurants. Ethnic restaurants were 1.74 times more likely than nonethnic restaurants to have critical violations. Meanwhile, independent restaurants were 1.64 times more likely than chain restaurants to have critical violations.
