What is driving increases in dietary quality in the United States?

Over 1994–2010, adult dietary quality in the United States increased by 10 percent. We find a shift in consumption between at-home and away-from-home food played a relatively minor role as compared to changes in demographics and educational attainment. The two largest contributors we identify include an increased usage of nutritional information and a shift away from relying heavily on price, taste, storability and ease of preparation when shopping for food. Our findings suggest nutrition policy discussions could focus on further shifting attitudes/preferences towards healthier diets while allowing consumers to better extract nutrition information when making food choices.

Firm listing status and the investment home bias

Are public firm investment rates more sensitive than private firm rates to new investment opportunities? We offer a new explanation for differences in public and private firm investment sensitivities: investment sensitivities differ because the type of investments favored by firms varies with their listing status. Specifically, we consider the geography of investment opportunities and find that private firms have a much stronger investment home-bias than similar public firms which makes their investment decisions more sensitive to local investment opportunities than public firms. Controlling for local investment opportunities explains four-fifths of the differential sensitivity between public and private firms not explained by more traditional measures of investment opportunities.     

Social capital as a facilitator of successful buyer-supplier performance management

Performance management in supply chains is an increasingly important, rapidly developing but challenging area. It may benefit from sufficient levels of social capital, such as frequent interactions between buyers and suppliers. However, social capital has not yet been studied as a facilitator of performance management. To bridge this knowledge gap, we examine buyer-supplier performance management and social relationship characteristics as perceived by suppliers. We analyze empirical data gathered through a survey of 482 suppliers by employing PLS-SEM and PLS-MGA. The findings elaborate on the role of cognitive, relational, and structural capital in performance management activities within a buyer-supplier relationship. Moreover, the results demonstrate how a supplier's positive perception, in the form of preferred customer status, can be facilitated through performance management activities. The findings reveal that there is a difference in the role of structural and relational capital between key and non-key supplier groups in performance management activities. We conclude that successful performance management in buyer-supplier relationships requires more than simply a system for sharing information. The mature use of performance measurement is also essential, with cognitive capital being especially beneficial in this endeavor.     

少数民族残疾人的社会经济状况

利用2006年第二次全国残疾人抽样调查数据对中国少数民族人群残疾现患率的流行特征、社会经济状况及其与汉族残疾人的差异进行比较分析。少数民族男性的残疾现患率(6.46%)高于女性(6.03%)。初中及以上教育程度的女性少数民族残疾人仅有10.04%。居住在农村的少数民族残疾人,大约有25%生活在国家规定的农村贫困标准以下,71%的农村少数民族残疾人没有参与任何形式的社会保险。农村、女性、老年残疾人是今后少数民族残疾人扶贫和社会保障覆盖重点干预对象;要优先提高女性残疾人的受教育水平。

人民币升值能改善日美与中国的贸易状况吗?——基于汇率经过效应的研究

有学者提出,被低估的人民币是中国贸易盈余和全球贸易不平衡的主要因素,因此,人民币升值有助于改善中西方的贸易状况。显然,这种观点的内在逻辑是:人民币升值将提高中国出口商品的价格,同时降低外国进口商品和服务的价格,即人民币升值存在较大的汇率经过效应(pass-though effect)。通过对人民币汇率经过效应的研究,发现人民币升值不能改善美国与中国的贸易状况,但能改善日本与中国的贸易状况;其差别的原因就在于贸易定价的不同。
