人口普查中遗漏人口数的估计

研究目标:用完整遗漏估计量替代目前使用的未匹配遗漏估计量、逆记录检查遗漏估计量和平衡推算遗漏估计量。研究方法:采取文献解读、成果借鉴和移植及实地调查相结合的方法,研究完整遗漏估计量及其方差估计。研究发现:人口普查遗漏估计不只是要提供遗漏估计值,还要揭示遗漏的原因及其遗漏者的特征;构造普查遗漏估计量,既要包括登记在事后计数调查人口名单而未登记在普查名单的单重遗漏人口,还要包括同时遗漏于这两项调查名单的双重遗漏人口。研究创新:提出完整遗漏估计量。研究价值:完整遗漏估计量有望应用于中国2030年普查遗漏估计,开创世界人口普查遗漏估计应用完整遗漏估计量的先河。     

A tripartite evolutionary game research on information sharing of the subjects of agricultural product supply chain with a farmer cooperative as the core enterprise

In order to explore the interaction law of information sharing behavior of decision-making subjects in the agricultural product supply chain, this paper establishes a tripartite evolutionary game mathematical model, uses the replicator dynamics equation to analyze the dynamic evolution process of the three-dimensional dynamic system, and carries out numerical simulation analysis. The results show that there are seven key factors affecting the information sharing decisions of the decision-making subjects. This paper explores the specific role of these influencing factors and finds ways to improve supply chain performance. Finally, the study proposes four suggestions for supply chain information sharing management.     

Australian consumer attitudes to health claim – food product compatibility for functional foods

This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how ‘attractive’, ‘believable’, and ‘new and different’ they found each concept and their ‘intention to try’. Each variable was significantly related to intention to try (p < 0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed.     

New evidence of regional income divergence in post-reform Russia

This article investigates regional income convergence in Russia during 2000–2008. We test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions. The study contributes to the existing literature by using the exponential smooth autoregressive Augmented Dickey–Fuller (ADF) unit root test in a panel setup, a novel econometric technique, which encompasses cross sectional dependence. Results show strong evidence of on-going regional income divergence in post-reform period.     

Community college economics instruction: Results from a National Science Foundation Project

The principal investigator of a National Science Foundation project, “Economics at Community Colleges,” surveyed community college economics faculty and organized workshops, webinars, and regional meetings to address community college faculty isolation from new ideas in economics and economics instruction. Survey results, combined with National Study of Postsecondary Faculty data, help fill a lacuna in information about community college faculty. A key finding is the reliance in community college economic instruction on part-time faculty, including many who do not hold a graduate degree in economics. The project's webinars reached the most community college faculty, while the workshops were most effective in improving economics instruction. Areas for future research are identified.

我国出口贸易摩擦预警机制的现状、问题与对策

我国“入世”以后,为了保证出口的稳定增长,维持正常的出口秩序,迅速建立了出口贸易摩擦预警机制并已发挥了重要的作用。然而,出口贸易摩擦出现的一些新特点,对正在完善中的预警机制提出了新的挑战。本文对我国出口贸易摩擦预警机制的现状和问题进行了分析,并提出了相应的对策。     

汇率预测的神经网络方法及其比较

浮动汇率兴起以来,大量的参数方法和非参数方法被用于汇率预测,神经网络是其中的一种.神经网络方法在汇率预测中的应用有三种不同的方法:同质神经网络模型、异质神经网络模型和神经网络组合模型.本文讨论了三种神经网络预测模型的特点以及局限性,并通过时这三种方法的比较得出结论:神经网络组合模型充分考虑了汇率的线性特征和非线性特征,比同质神经网络和异质神经网络预测模型更系统、更全面,能更好地进行汇率预测.
