Time variation in the cointegrating relationship between stock prices and economic activity

The present paper examines whether there exists a long‐run cointegrating relationship between a stock market index and output and interest rates. Moreover, estimation is conducted over the full sample and both a recursive and rolling sample to examine any time variation in the nature of the relationship. The results support evidence of a single cointegrating vector, where stock prices typically exhibit a positive relationship with industrial production and a negative relationship with interest rates. However, there is significant time variation and periods of time where contrary results are observed. As such any model of stock prices needs to account for such time variation     

Considering the nuclear option: Hidden benefits and social costs of nuclear power in the U.S. since 1970

Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear.     

中国利率政策与房地产价格的互动关系研究

本文通过建立结构向量自回归模型对中国房地产价格与利率政策之间的互动关系进行了探讨,发现中国的利率政策并不能对房地产价格形成有效的调节,造成了利率政策房地产价格传导渠道的失效;相反,房地产价格冲击对利率政策却具有显著的正向影响,说明中国历史上的利率政策制定的确参考了房地产价格因素,并对其作出了一定的反应。本文还利用模拟分析对样本期间内我国利率政策的实施效果进行了分析评价。研究结论对中国中央银行利率政策的有效执行及房地产市场调控具有重要政策启示。     

Backcasting energy futures using industrial ecology

Backcasting has been widely used for developing energy futures. This paper explores the potential for using industrial ecology to guide the development of energy futures within a backcasting framework. Building on the backcasting work of Robinson [1], a seven step method is presented to embed industrial ecology principles within the development and assessment of future scenarios and transition paths toward them. The approach is applied to the case of backcasting regional energy futures in the Latrobe Valley, near Melbourne, Australia. This region has substantial brown coal deposits which are currently mined and used in coal-fired power stations to generate electricity. Bounded by a sustainability vision for the region in a carbon-constrained world, regional industrial ecologies in 2050 were backcast around three themes: bio-industries and renewables (no coal usage); electricity from coal with carbon capture and storage (low to high coal usage); and coal to products such as hydrogen, ammonia, diesel, methanol, plastics and char (demonstrating medium to high overall coal use relative to current levels). Potential environmental, technological, socio-political and economic impacts of each scenario across various life cycle stages were characterised. Results offer a platform for regional policy development to underpin deliberation on a preferred future by the community, industry and other stakeholders. Industrial ecology principles were found to be useful in backcasting for creatively articulating alternative futures featuring industrial symbiosis. However, enabling the approach to guide implementation of sustainable transition pathways requires further development and would benefit from integration within the Strategic Sustainable Development framework of Robèrt et al. [2].

房价波动与财政收入：传导机制与实证分析

本文分析了在现行的地方政府控制土地出让收益模式下,城市房价波动对财政收入的影响机制。研究发现：土地出让收入、财富效应、房地产税收以及房价波动的产业关联效应构成了财政增收的四种机制。基于2000—2010年的35个大城市的面板数据,我们定量分析了房价波动对城市财政收入的影响。结果显示,房价和总产出的变动显著影响了财政收入,从而为财政收入的高速增长提供了一种基于资产价格的解释。

浅谈山西煤炭市场营销策略

我国已经加入WTO，企业所面临的营销环境发生了深刻的变化。为此，山西煤炭企业必须不断调整营销观念、加强品牌管理、创新营销模式，同时加强营销队伍的建设，并做好市场调研工作。只有这样才能在国际市场竞争中立于不败之地。     

外部压力、公司治理与环境信息披露质量——基于煤炭行业上市公司的实证检验

将煤炭行业上市公司作为研究对象,在运用内容分析法对其2008—2012年环境信息披露质量进行评价的基础上,实证检验外部压力、公司治理对环境信息披露质量的影响。研究发现,样本期间我国煤炭行业上市公司环境信息披露质量整体呈上升趋势,但各公司间差异较大;外部压力对环境信息披露质量起到了积极的提升作用,环境信息披露制度的颁布和执行成为公司绿色行为的重要驱动力;有效的公司治理能明显改善环境信息披露质量,尤其是股权制衡机制、董事会和独立董事作用显著,但控股股东并未发挥出应有的作用。     

经济环境、调控政策与区域房价——基于面板数据同期强相关视角

本文关注经济环境与调控政策等共同冲击对区域房价的影响,强调重大事件与我国房地产市场变动的内在关系;试图从同期相关视角出发,构建区域房价的共同因子模型,并利用2002第一季度至2012第四季度省际面板数据进行实证分析。结果表明：（1）区域房价受经济环境与调控政策两个因子影响;（2）相对于其它经济事件,次贷危机对我国各地区房价的影响最大,相对于其它时期的房价调控政策,2003年-2008年的调控政策更为有效;（3）各地区对共同冲击的反映是异质的。从而,政府在制订房价调控政策时应充分考虑市场反应,以促进房地产市场的协调平稳发展。
