宏观审慎政策理论基础解析

宏观审慎政策是在本次金融危机后由国际清算银行牵头,于2010年在G20国家峰会上通过的未来全球金融监管通行规则。现有中文文献多将目光聚焦在对宏观审慎政策的目标、工具与有效性的认识和解释上,本文则是从宏观审慎政策的理论基础出发,从不同的角度和侧面来描述刻画宏观审慎政策的目标和内容,厘清其完整脉络,为全面实施宏观审慎监管提供理论依据。

Do rating agencies’ decisions impact stock risks? Evidence from European markets

This article analyses the effect of rating agencies’ decisions on stock risks for European issuers concerning five kinds of events. Our approach is an extension of dummy variable regression event study methodology, using a GARCH(1,1) estimation to capture simultaneously the impact on both systematic and specific stock risks. This new methodology allows us to obtain both global results by categories of rating decisions and individual results, event by event. We document, globally, a positive impact of upgrading on systematic risk, a negative impact of rating confirmation on specific risk, and no significant impact in all other cases. Regarding event-by-event results, the proportion of rating actions exhibiting a significant effect on risk is almost always observed between 20% and 30%. The weak evidence of a global effect on systematic risk may be due to the lack of informational content of the rating decisions on the stocks’ risk, or the existence of rebalancing effects between systematic and idiosyncratic risks. Furthermore, it should be noticed that the decline in volatility in case of a rating affirmed is an insight of the certification role played by the agencies.     

Re-examination of wage, employment, and hours adjustments: what is crucial for differences in the adjustments?

Manufacturing wage, employment, and hours adjustments are significantly different among developed countries, typically between Japan and the US. The problem of explaining the differences is closely related to that of what effect the extent of wage flexibility has on labor market adjustments. However, prevailing theories are invalid or incomplete for explaining the differences. The differences in the adjustments cannot be unrelated with institutional features of the labor market. Indeed, the extent of wage flexibility depends on the differences in the institutional features. Using a new model with such an idea, this paper theoretically re-examines the cause of the differences in the adjustments. The crucial causes are the characteristics of wage flexibility as well as the differences of the institutional features. The characteristics are that wage adjustment is discontinuous, infrequent, and has a lower limit in comparison with changes in demand.     

Slippage Effects of the Conservation Reserve Program

Each year, billions of dollars of public funds are expended to purchase conservation easements on farmland. One unintended impact of these programs is that they may bring non-cropland into crop production. Such a slippage effect can be caused by increased output prices and by substitution effects. This article shows that for each one hundred acres of cropland retired under the Conservation Reserve Program (CRP) in the central United States, twenty acres of non-cropland were converted to cropland, offsetting 9 and 14% of CRP water and wind erosion reduction benefits, respectively. Implications of these results for the design of conservation programs are discussed.     

基于SolidWorks Simulation的装配式桥式电动升降平台附墙架设计与分析

以装配式桥式电动升降平台附墙架结构为研究对象，利用Soildworks软件，进行结构的设计和有限元模型的建立。通过对不同附着结构形式的强度、刚度及稳定性的分析，选取了较优的结构形式，研究了附墙架组成杆件截面尺寸、附墙架长度对其各项性能的影响。研究结果表明，对于附墙架结构形式，采用单侧两杆式附墙架结构形式较为经济；附墙架拉杆截面尺寸为40 mm时，各构配件性能最优；附墙架拉杆长度2 500 mm是附墙架应力、变形位移值的拐点，为保证使用的安全性，长度应小于2 500 mm。
