中俄能源合作现状分析及对策研究

在当今世界，能源已经成为各个国家最关注的问题之一。俄罗斯有着天然的能源优势，是能源供应大国，而中国是能源需求大国，因此，中俄两国开展能源合作拥有广阔的前景。本文在分析中俄能源合作的现状及战略意义的基础上，从理论的角度分析了两国进行能源合作的可行性，并从现实的角度分析了中俄能源合作的障碍，从而对如何进一步加深中俄能源合作提出了对策建议。     

我国黄金期货市场价格发现与套期保值功能——基于ARDL-ECM模型

文章收集了2011-2013年的黄金期货和现货价格数据,采用ARDL-ECM模型分析我国黄金期货价格和现货价格之间的长期均衡和短期动态关系。研究表明:我国黄金期货市场具有完美且有效的套期保值功能,但尚不具有价格发现功能,其运行效率有待提高。     

社会距离对大学生道德判断的影响

目的：基于解释水平理论,探讨社会距离是否影响大学生的道德判断,为高校对学生进行道德教育和人格塑造提供心理学依据。方法：采用内隐联想测验（Implicit Association Test,IAT）研究范式,随机抽取63名宁夏大学本科生进行实验。结果：被试在相容任务下的平均反应时显著短于在不相容任务下的平均反应时（t=-4.192,df=59,P〈0.001）;女生在相容任务下的平均反应时显著短于男生在相容任务下的平均反应时（F（1,58）=10.27,P〈0.05）,男女生的IAT效应值存在显著性差异（t=-2.286,df=58,P〈0.05）。结论：大学生的道德判断受到社会距离的影响。大学生倾向于将积极道德词与熟人联结,而将消极道德词与陌生人联结。此外,社会距离对大学生道德判断的影响存在性别差异。     

Pricing-to-Market: Price Discrimination or Product Differentiation?

We employ a vertical differentiation model to examine the potential bias in pricing-to-market results when using export unit values aggregating differentiated products. Our results show that: (i) false evidence of pricing-to-market is always found when using unit values, whether the law of one price holds or not; and (ii) the size of the bias increases with the level of product differentiation. Our simulation results support those conceptual findings. Thus, some of the positive pricing-to-market results in the literature could be an artifact of the product heterogeneity embodied in unit values rather than evidence of imperfect competition.     

黑龙江省耕地非农化与经济发展的Granger因果关系研究

研究目的:分析黑龙江省耕地非农化过程的内在原因,以助于协调黑龙江省耕地非农化进程与经济发展的关系,使耕地保护工作与未来经济运行相一致。研究方法:运用Granger因果关系检验法,利用Eviews4.1软件分析。研究结果:城市化进程对耕地非农化进程的影响与经济增长对耕地非农化的影响并不一致,城市化进程对耕地非农化的影响更加显著。因此,要从根本上解决耕地非农化与经济发展之间的矛盾须将城市化作为切入点。     

Evolving splines and seasonal unit roots in weekly agricultural prices

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series.     

The Importance of taste in experimental auctions: consumers’ valuation of calorie and sweetener labeling of soft drinks

A majority of purchases that consumers make are classified as repeat purchases. One of the main reasons why consumers make repeat food purchases is the food's taste. Therefore, we examined the importance of including taste testing in nonhypothetical experimental auctions. Specifically, we used two experiments to determine consumers’ willingness to pay for soft drinks labeled with different calorie and sweetener information. In Experiment 1, participants tasted the soft drinks prior to the bidding rounds. In Experiment 2, participants did not taste the soft drinks prior to the bidding rounds. Bidding behavior for the soft drinks was significantly different between Experiment 1 and Experiment 2. Results suggest that including taste testing in the design of experimental auctions is important to accurately capture consumers’ willingness to pay for foods that are purchased repeatedly. Results also imply that policies aimed at combating obesity by making the calorie content of foods more visible may not produce desired outcomes.     

Do rice prices follow a random walk? Evidence from Markov switching unit root tests for Asian markets

This study revisits the issue of mean reversion in the import rice prices of six Asian countries over the period between 1995 and 2015. Augmented Dickey Fuller tests with a conventional linear regression model support the presence of a unit root in the levels of the price data. However, when regressions allow for Markov switching in coefficients and variances to capture periodic shifts in levels and volatilities, there is strong evidence against the unit‐root null hypothesis in favor of stationarity over much of the observation period.
