The Transmission of International Shocks: A Factor-Augmented VAR Approach

The empirical literature on the transmission of international shocks is based on small -scale VARs. In this paper, we use a large panel of data for 17 industrialized countries to investigate the international transmission mechanism, and revisit the anomalies that arise in the empirical literature. We propose a factor augmented VAR (FAVAR) that extends the model in Bernanke, Boivin, and Eliasz (2005) to the open economy. The main results can be summarized as follows. First, the dynamic effects on the UK economy of an unanticipated fall of short-term interest rates in the rest of the world are: real house price inflation, investment, GDP and consumption growth peak after 1 year, wages peak after 2 years, and CPI and GDP deflator inflation peak during the third year. Second, a positive international supply shock makes the distribution of the components of the UK consumption deflator negatively skewed. Third, in response to a domestic monetary shock, we find little evidence of the exchange rate and liquidity puzzles and little evidence of the forward discount and price anomalies.

HFC-SCDMA抗汇聚噪声干扰能力的重点抽样仿真

基于MATLAB6．1平台，使用重点抽样（Importance Sampling)方法，对采用SCDMA体制的HFC上行信道抗汇聚噪声干扰的性能进行仿真，仿真中常用的Monte-Carlo方法由于受SCDMA系统巨大的计算量限制而不具有实用性，重点抽样技术是一种方差减少技术，它能显著地减少运算时间，SCDMA系统仿真同样的仿真精度条件下，重点抽样与Monte-Carlo仿真相比，重点抽样技术能显著地降低运算量。     

不同层级性别多样性变量和离职意图关系的实证研究

在对国外多样性研究做出总结的基础上,考查了不同层级性别多样性变量对于员工离职意图的影响,在对298个样本作统计分析后,发现高层以及基层管理者性别多样性变量对离职意图有显著影响作用,这就为影响离职意图的前因变量中引入了性别多样性变量。     

科学发展观的生态价值诠释

生态价值观是在全球性的环境保护运动和生态伦理学的基础上产生和发展起来的,在各方面引起了深刻的影响。要实现可持续发展,必须树立科学的生态价值观,即在人与自然的关系上,坚持以人为本,在全面、协调、可持续的基础上,处理好生态环境与人类生存、发展之间的关系。

Do Market‐based Indicators Anticipate Rating Agencies? Evidence for International Banks

This paper analyses the ability of credit default swap (CDS) spreads, bond spreads and stock prices to anticipate the decisions of the main rating agencies, regarding the largest international banks. Conditional on negative rating events, all the three indicators show significant abnormal changes before both announcements of review and actual credit rating changes, but rating actions still seem to convey new information to the market. Results for positive rating events are less clear‐cut with the market indicators generally showing abnormal behaviours only in conjunction with the events. As for the predictive power of the financial indicators examined, the CDS market is particularly useful for negative events and stock prices for positive events. However, all indicators also send many false signals and are to be interpreted with care.     

Rethinking Macroeconomic Policy

The great moderation lulled macroeconomists and policymakers alike in the belief that we knew how to conduct macroeconomic policy. The crisis clearly forces us to question that assessment. In this paper, we review the main elements of the precrisis consensus, identify where we were wrong and what tenets of the precrisis framework still hold, and take a tentative first pass at the contours of a new macroeconomic policy framework.     

废旧家电回收站选址问题的多目标满意优化方法

为促进废旧家电回收利用,提出一种基于多目标满意规划的废旧家电回收站选址方法。考虑到回收企业和家电用户对回收站选址的不同要求,建立了追求企业总费用最小化和用户综合运送满意度最大化的多目标满意规划模型。该模型可以确定回收站的开设位置及其服务用户,有助于保护用户运送废旧家电的积极性。为便于模型应用,给出了基于满意优化理论的模型解算方法,通过实验验证了模型和算法的有效性。在实验过程中,比较了分别利用儿何平均式和算术平均式表达用户综合运送满意度的模型解算结果,结果表明,几何平均式更有利于废旧家电的足量回收。
