影响酒精酵母发酵效果的因素研究

酒精酵母发酵作为现代工业的一个重要指标,酒精酵母的发酵效果也受到了人们的重视。在同样的条件下使酒精酵母拥有更好的发酵效果是工业造酒想要达到的目标。通过实验来探究在酒精酵母发酵过程中影响其生长速度与繁殖的因素。酒精发酵过程中蔗糖会分解成果糖和葡萄糖,酵母发酵过程中首先利用葡萄糖而后利用果糖,果糖就会成为残留物,使得其产生差异性。通过实验发现影响酒精酵母发酵效果的因素有温度、通风、pH、尿素、糖比例等。     

How about selling commodity futures losers?

This paper explores the benefits of extending the investment universe to commodity futures, from the perspective of momentum traders. We find that the growth-optimal portfolio includes negative (positive) weights on commodity futures losers (stock winners). Motivated by this finding, we construct a joint momentum strategy, buying stock winners and selling commodity futures losers, and show that it generates an average monthly return of up to 1.91% and provides much lower skewness (0.04) and kurtosis (1.27) than a traditional stock momentum strategy. It also greatly improves profitability, especially in unfavorable market states, and thus effectively manages tail risk.     

平均工资、缴费下限与养老保险参保

研究目标：研究养老保险参保缴费逆向激励产生的原因、作用机制以及后果。研究方法：通过构建刻画参保者行为的生命周期模型,数值模拟分析平均工资增长对参保者效用的影响;借助自然实验构建固定效应工具变量回归,实证研究平均工资增长对参保行为的影响。研究发现：基于在岗职工平均工资的缴费下限设定,增加了低收入者的实际缴费负担,随着平均工资的提高,在借贷约束的限制下,为保障当期消费,低收入者会退出养老保险制度;平均工资上涨会显著降低参保职工人数,导致缴费遵从度下降。研究创新：通过研究平均工资变化对实际费率负担的影响,揭示低收入者的参保行为。研究价值：为养老保险制度改革,提供理解参保者微观行为的理论框架和实证依据。     

Service quality and its effect on customer satisfaction and customer behavioral intentions: hotel and ryokan guests in Japan

This study analyzes the effect of service quality on customer satisfaction and customer behavioral intentions at hotels and ryokan (traditional Japanese inns). In this empirical research, questionnaires were sent to guests at seven sites: three hotels and four ryokan. Service quality, as perceived by guests, affected customer satisfaction and customer behavioral intention. Results from this empirical study show strong evidence of service quality as perceived by guests being influenced by the type of accommodation. Also, among service quality factors, “physical aspect” had the most powerful impact on customer satisfaction and customer behavioral intention. “Creativeness” ranked second, followed by “unexpected service” and “encounter performance”. The prominence of physical aspects probably reflects the distinctiveness of the service of offering a one-night stay. However, as a certain level of physical facilities is taken for granted at lodging facilities above a certain price, “creativeness”, the second most powerful factor, becomes decisively important.     

Voluntary disclosure practices by foreign firms cross-listed in the United States

This is one of the first large-scale studies to examine the voluntary disclosure practices of foreign firms cross-listed in the United States. We proxy for voluntary disclosure using three attributes of firms’ management earnings guidance: (1) the likelihood of issuance; (2) the frequency of earnings guidance; and (3) a guidance quality measure. After first establishing that market participants view these firms’ disclosures as credible and economically important (i.e., the disclosures are negatively related to analyst forecast errors and the implied cost of equity capital), we compare cross-listed firms’ disclosure practices with comparable US firms and explore variations in disclosure practices among cross-listed firms. We find that cross-listed firms issue less frequent and lower quality management earnings guidance than comparable US firms. We further show that the gap between US and cross-listed firms widened after passage of Regulation FD, a regulation which induced greater public disclosure of firm-specific information. Focusing on the sample of cross-listing firms, we show that firms from common-law countries disclose more than firms from code-law countries. Finally, our results indicate that cross-listed firms that do not list on an organized US exchange provide more frequent and higher quality disclosure than those that do list on organized exchanges.     

建筑工程无标底招标理论与实践

随着中国建筑业管理体制改革的不断深化，招投标制度在中国得以推广应用，但在招投标机制方面还存在不足，有待完善。文章通过无标底招投标的博弈论基础，分析了无标底招标的意义和作用，同时对无标底招标的实施提出了一些相应的措施和建议，最后指出，随着中国加入WTO，与国际接轨，推广无标底招投标方法是我国建筑业招投标制度改革的当务之急。     

贸易信用、经济政策不确定性与企业破产风险

文章主要考察了经济政策不确定性加大的背景下,贸易信用在企业破产风险传播和防范中的作用。研究发现,贸易信用在资产端具有显著的风险引致效应,在负债端具有显著的风险化解效应,当经济政策不确定性上升时,企业通过主动调整贸易信用融出和贸易信用净额冲抵了部分不利影响。分类研究表明,贸易信用融出显著提高了外部融资依赖低企业的破产风险,贸易信用融入显著降低了外部融资依赖高企业的破产风险,经济政策不确定性则在一定程度上弱化了这些作用。贸易信用融出和贸易信用净额均显著提高了ST类企业的破产风险,同时经济政策不确定性显著强化了这一作用,这显著区别于非ST类企业。内生性检验及多种稳健性检验均显示研究结论是稳健的。
