西部地理环境对当地媒介政策的影响研究——以我国西部地区新闻阅评制度调查研究为例

在媒介地理学的视野下，新闻媒介政策在一定意义上可以被看做地理环境造就的延伸物。通过东西部地区新闻阅评制度的调查对比分析，本文认为，西部地区新闻阅评制度的现状更显示出地理环境的影响力。     

Tuition increases Geaux away? Evidence from voting on Louisiana’s amendment 2

In many states, public institutions of higher education have the autonomy to raise tuition. This has not been the case in Louisiana since a 1995 constitutional amendment required a two-thirds majority of the state legislature for any tuition increase. In November of 2016, voters in Louisiana rejected Amendment 2, a constitutional amendment that would have given state institutions of higher education autonomy in setting tuition. We examine parish-level voting on Amendment 2 using an empirical political economy model and find that parishes with a greater percentage of African-Americans and university employees were more likely to vote yes. Student enrolment at public institutions seemingly did not play a role in Amendment 2 losing.     

“牛市”和“熊市”对信息的不平衡性反应研究

“利好”和“利空”信息对股票市场具有不平衡性的影响 ,研究这一现象对资产定价、投资组合构造及风险头寸确定都有重要作用。而新信息的出现对股票市场的影响应该区分股市所处的位置 ,这一点正是已有的波动性研究所忽视的。中国股票市场总体上不平衡性信息表现与国外不同 ,本文将股票市场波动划分为“牛市”和“熊市”两个阶段 ,采用EGARCH模型实证研究我国股票市场在牛市和熊市阶段对“利好”与“利空”的不平衡性反应特征。然后从投资者预期、结构、心理和交易机制等方面解释产生“强市恒强、弱市恒弱”现象的原因 ,指出进一步研究的方向 ,以期为投资者选择投资策略和政府制订政策提供参考     

反倾销规则的悖论

WTO现行的反倾销规则基本是在1947年确定的GATT第六条的基础上，经1994年乌拉圭回合修订而来的。从其理论、行为、本质与事实上都有不尽合理的地方，其规则本身也漏洞百出。因此，WTO必须顺应时代发展的需要，加大改革的步伐，增加国际监管的力度。中国有责任敦促WTO尽快改革现有反倾销规则中不合理的部分，从根本上解决与各国之间的贸易摩擦，全面改善国际贸易环境。     

经济新闻深度报道的深度构成

浓郁的经济味、较强的思辨色彩、观点的创新性、前景的预测性是经济新闻深度报道深度构成的突出特征。经济新闻深度报道的深度构成过程体现在良好的理论素养与宏观意识的审视相结合,内涵丰富的题材与全面深入地发掘相结合,多种表达方式与实写虚评相结合,多种文体形式与多种构成方式相结合。     

金庸《明报》的经营探析

《明报》是香港最有影响的报纸,有人把它比喻成香港的《泰晤士报》。《明报》的成功,可归功于金庸个人的远见。究其原因与成功的报业经营理念有不可分割的关系。无论是金庸的社论、对中国问题的独到见解,还是金庸的用人之道。副刊经营、运作在今天都值得报业经营者借鉴与学习。     

专利当然许可的制度定位与规则重构

专利当然许可作为一种特殊的专利许可类型,肇始于英国,后为德、法等多国移植,我国《专利法修订草案（送审稿）》也将这一制度引入。提升专利信息质量和降低专利交易成本是专利当然许可的重要制度效用,但其在适用范围上的局限性则制约着制度效用的发挥。为保证当然许可制度在不同领域的有效运行,有必要根据私益主体和公益主体所资助专利技术的不同属性,构建差异化的当然许可规则。     

News Sentiment: A New Yield Curve Factor

The authors show that sentiments from newspaper articles can explain and predict movements in the term structure of U.S. government bonds. This effect is stronger at the short end of the curve, coinciding with greater volatility and investors' need to continually reassess the Fed's reaction function. Facing such uncertainty, market participants rely on news and sentiment as a central element in their decision-making process. Considering this dependence, the authors propose a new yield curve factor—news sentiment—that is distinct from the 3 established yield curve factors (level, slope, and curvature) as well as from fundamental macroeconomic variables.     

效率、公平与区域协调发展

任何国家都存在由区域差异而导致的区域差距,政府的责任是要控制乃至缩小这种区域差距,实现区域的协调发展.改革开放以来我国的区域差距逐步扩大,这与中央政府区域政策目标在效率与公平上的孰为\"优先\"的偏差有关.本文认为,效率与公平是两个不同层次的概念,中央政府应该确立效率与公平兼顾的区域政策目标,并建议国家开征\"统筹税\",促进在效率与公平兼顾基础的区域协调发展.     

The distance bias in natural disaster reporting – empirical evidence for the United States

Whenever governments or international organizations provide aid in the aftermath of natural disasters, they typically justify this support by humanitarian motives. Previous empirical research found that media reports on natural disasters have a systematic impact on the amount of provided disaster aid. While this is unproblematic as long as media reports are unbiased and thus deliver an undistorted picture of the occurrence and severity of worldwide occurring disasters, systematic reporting biases would lead to distorted aid flows and perhaps other distortions like an insufficient perception of a region in international organizations. Based on data on three US news shows we show that disaster reporting is subject to a distance bias, e.g., the likelihood that a disaster is covered by the media depends on the distance between the country where the media are located and the country where the disasters occur. We also find evidence that besides the distance bias the state of economic development of a country and importance as export markets have a positive effect on the probability that US news shows are reporting on a natural disaster. As a result, international aid flows might be systematically biased and not distributed in line with the needs of the victims.     

股市杠杆效应与溢出效应实证分析-GARCH模型之应用

通过使用广义自回归备件异方差GARCH模型对我国股市收益波动性的非对称性及波动性之间的互动性进行分析发现;在我国股票市场上，两效应在扩充样本区间内与国内文献构成一定的差异，与国外文献趋近一致。从此意义上说，我国股市正逐渐趋于理性，走向成熟。     

专利法修改与企业创新——来自上市公司的实证研究

法律制度完善可以通过不同途径推动我国经济高质量发展,相关法律制度变革可以提升财务风险较小的企业创新产出水平。利用2009年专利法修改实施这一难得的准自然实验,通过构造双重差分模型对法律修改与企业创新的因果关系进行实证检验。结果发现,拥有较低财务风险的企业,企业创新产出数量和质量均显著提升。进一步分析表明,此次法律修改对负债规模更小、偿债能力更强、盈利能力更强、股权集中度更高的企业而言,其企业创新提升作用更显著。同时,研究结论为《中华人民共和国专利法》的第四次修改提供了法律变革层面上的经验证据,为法律修改如何影响实体经济发展提供了有价值的研究思路。     

Name-Based Behavioral Biases: Are Expert Investors Immune?

The market comprises investors with a broad range of expertise. As a result, investors may make decisions differently from one another. Research reveals that investors use name-based heuristics, or short-cuts, including alphabetical ordering (Itzkowitz, Itzkowitz, and Rothbort []), name fluency (Anderson and Larkin [], Green and Jame []), and name memorability (Grullon, Kanatas, and Weston []) when trading stocks, resulting in irrational decisions. Because experts and novices process information differently, name-based biases may not affect all investors equally. The authors test and confirm the hypothesis that, compared to novices, expert investors are relatively immune to name-based biases.
