A brief technology assessment of the Carbon Dioxide effect

Significant increases in atmospheric carbon dioxide are occuring as a result of fossil fuel combustion. More than a four-fold increase over preindustrial levels may occur by the year 2100. Heating of the atmosphere, changes in precipitation patterns and global storm paths, and other resulting effects are sure to cause significant social changes. This article is essentially a methodological case study demonstrating a useful but inexpensive type of technology assessment. It summarizes current research findings on “the CO₂ effect,” and presents hitherto unpublished findings that resulted from a brief but systems-oriented approach. These findings suggest that most published forecasts of phenomena associated with a CO₂ buildup may be systematically low because various positive feedback relationships are not reflected.

Problems of private industrial economic development and its countermeasures for Zigong City,Sichuan Province,China

The differences of regional economic development between underdeveloped areas and developed areas are mainly embodied by different levels of private economic development. Since 20-year reform and opening-up to the outside world, the private industry of Zigong has developed gradually, become more and more economically competitive, and played a more and more important role in the economic structure of Zigong. This paper analyzes the problems of private economy and its countermeasures based on the research on its status quo.

中国乡村城市化浅析

实现乡村城市化是我国21世纪实现工业化、现代化重要战略布置，也是我国经济社会发展面临一项十分紧迫的任务。正如马克思在《政治经济学批判》中指出：“现代的历史是乡村城市化，而象古代那样，是城市乡村化。”因此，寻求一条适合我国国情和地区特征乡村城市化道路，探索我国乡村城市化发展的战略思想，是当代城市规划工作面临的一个严峻课题，也是制定跨世纪城市规划的重要组成部分。     

The effect of management incentives and cross-listing status on the accounting treatment of R&D spending

This paper investigates the effect of management incentives and cross-listing status on the accounting treatment of research and development (R&D) spending for a sample of Canadian hi-tech and biopharmaceutical firms. U.S. GAAP adopts an immediate expensing rule for all R&D spending except for software development costs for which technological feasibility has been established. Contrary to the U.S., Canadian and international standard setters recommend capitalization if development costs meet certain criteria. Because those criteria are largely based on management judgment, capitalization of R&D spending is an accounting choice that can be used for income manipulation or signaling.Using a logit model, we examine how the decision to capitalize R&D spending is influenced by the cross-listing status and several other key firm characteristics that are well documented in the accounting literature. We find that the probability of capitalizing R&D spending increases for cross-listed and non-cross-listed firms in the software industry. The probability of capitalizing R&D spending also increases for firms that are more leveraged, more mature, and have higher level of cash flows from operations. However, the probability of capitalizing R&D spending decreases for larger corporations, firms with more concentrated ownership and highly profitable firms. Overall our results indicate a preference for Canadian firms in the software industry to emulate U.S. accounting practices for R&D spending. They also suggest that firms use the decision to capitalize or expense R&D spending as an earning management tool to either meet debt covenants or to smooth income.     

逃税规模的衡量

逃税造成了政府财政收入的减少,因而政府理所当然地关心社会中的逃税程度,而且逃税程度的大小也代表了一国税务机关税收征管成效的高低.因此从这个意义上讲,对逃税规模的衡量就显得必要了.不过,由于纳税人的逃税行为是隐蔽的,故很难对逃税规模进行直接有效的衡量,尽管如此,还是存在一些方法从侧面去测算一国的逃税规模的.     

Monetary policy and stock valuation: structural VAR identification and size effects

This paper examines the relationship between the US monetary policy and stock valuation using a structural VAR framework that allows for the simultaneous interaction between the federal funds rate and stock market developments based on the assumption of long-run monetary neutrality. The results confirm a strong, negative and significant monetary policy tightening effect on real stock prices. Furthermore, we provide evidence consistent with a delayed response of small stocks to monetary policy shocks relative to large stocks.     

Gentrifier? Who,Me? Interrogating the Gentrifier in the Mirror

Schlichtman and Patch suggest that there is an elephant sitting in the academic corner: while urbanists often use ‘gentrification’ as a pejorative term in formal and informal academic conversation, many urbanists are gentrifiers themselves. Even though urbanists have this firsthand experience with the process, this familiarity makes little impact on scholarly debate. There is, Schlichtman and Patch argue, an artificial distance in accounts of gentrification because researchers have not adequately examined their own relationship to the process. Utilizing a simple diagnostic tool that includes ten common aspects of gentrification, they compose two autoethnographic memoirs to begin this dialogue.
