对目前通货膨胀现象的理论分析

本文通过对哈耶克有关文献的梳理,着重指出目前的通货膨胀是一种"凯恩斯的通货膨胀",进而从理论上指出:凯恩斯通货膨胀是一种"人为"性质的通货膨胀,是一种忽视生产过程和结构的通货膨胀,是一种在经济和政治层面上将造成危害的通货膨胀。在国内外通货膨胀已存蔓延之势的情形下,批判凯恩斯通货膨胀将为中国制止通货膨胀从心理、政治和现实三个方面提供思想资源。     

超宽带穿墙探测雷达的运动目标检测技术

提出了利用低频超宽带(UWB)脉冲信号实现穿墙探测的设想，研究了超宽带穿墙探测雷达(UWB—TWDR)的运动目标回波信号模型，并基于运动目标回波信号的相关性，利用相干叠加原理对多次观测的结果实现运动目标的检测。最后通过具体的穿透混凝土砖块墙壁实测实验验证了上述设想和算法。     

资金合理流动:理财目标的现实考察

本文通过对企业目标的考察,认为以企业的社会使命为企业的目标才能使企业有所发展,而要做到这一点,必须以资金合理流动作为企业财务目标,才能使企业的长久目标有可能实现。资金合理流动作为理想企业目标与现实存在的结合就成为了必然。     

混凝土靶上边界对射孔器穿深性能的影响

混凝土靶是射孔器检测最常用的靶体之一，由于混凝土靶为有限边界靶体，其边界效应对射孔器各项性能指标必然存在影响．从而影响检测的准确性。以混凝土靶上边界对穿孔深度的影响为例进行研究，从而确定混凝土靶上边界对射孔器穿孔深度的影响程度。     

Open Market Operation Effectiveness in China

This paper examines the effectiveness of target rate guidance in open market operation by the central bank in China (PBOC). We find that target rate change in open market operation is effective in adjusting the short-term Treasury rates. The target rate changing direction is more effective than the target rate changing level. There is no significant asymmetry in the effectiveness between the target rate increase and target rate decrease. We also document that the effectiveness of the target rate is conditional on liquidity operation of the same direction, especially when they both aim to loosen the monetary policy. Furthermore, consecutive operations with higher intensity appear to be more effective in adjusting the market interest rate.     

From Financial Repression to External Distress: The Case of Venezuela

Recent work suggests a connection between domestic debt and external default. We examine potential linkages for Venezuela, where the evidence reveals a nexus among domestic debt, financial repression, and external vulnerability. The financial repression tax (as a share of GDP) is similar to OECD economies, in spite of higher debt ratios in the latter. The financial repression “tax rate” is higher in years of exchange controls and legislated interest rate ceilings. We document a link between domestic disequilibrium and a weakening of the net foreign asset position via private capital flight. We suggest these findings are not unique to Venezuela.     

成本冲击、通胀容忍度与宏观经济政策

与之前比较,2010年以来此轮通胀成本冲击型特征十分明显（主要表现为国际大宗商品价格高企和国内劳动力成本上升）。在此背景下,是否应提高对通胀的容忍度以及宏观政策如何有所作为已成为热门话题。目前国内外已经有一些对通胀容忍度的探讨,但规范性的研究论文并不多见。本文在多恩布什-费雪（Dornbusch Fischer）框架基础上,结合中国实际,创新性地区分大宗商品价格和劳动力成本冲击（尤其是B S效应）对总供给以及宏观经济的不同影响机制,探讨有关通胀容忍度以及宏观政策应对问题。     

需求冲击与通货膨胀——基于中国的经验研究

通过使用2005年1月至2007年12月的月度数据,借助向量自回归模型,分析了需求因素对近期中国通货膨胀冲击的影响.研究结果显示:需求冲击是中国本轮通货膨胀压力上升的重要原因.其中,投资需求和消费需求对通货膨胀率上升的影响作用明显,而净出口对通货膨胀率上升的影响并不显著.因此,抑制总需求过快增长.将是控制物价上涨、保持宏观经济稳定的重要途径.     

创新环境及其政策的出发点：兼论增强区域的全球化竞争力

本文对创新的环境内涵做了深入的描述和探讨,并以此导出２１世纪中国的创新体系的设想。首先,概括阐述了古典的区域增长模式,总结评价并指出等级规模原则、分散式集中原则、空间功能分工原则和等价原则今天对发展中的国家仍然有重要的意义。接着对创新环境的内涵进行广泛的描述和探讨。最后导出了在经济全球化背景条件下构造区域创新体系的设想。     

Corporate Stock and Bond Return Correlations and Dynamic Adjustments of Capital Structure

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case.
