日本政府债务问题分析

日本政府债务占GDP的比例已连续多年居发达国家之首,且这一比例仍在不断增长之中。通过分析日本的债务困境,对我们有几点启示：一是积极的财政政策要适度;二是通缩环境中要有意识的控制政府债务规模;三是经济危机过后要警惕债务危机。     

Public sector layoffs, severance pay, and inflation in the small open economy

Because severance pay is worth 2–5 years of wages in many LDCs, public sector layoffs increase the fiscal deficit in the short run. Nevertheless, generous severance pay is not as serious a macroeconomic problem as generally thought. In the case where the fiscal deficit is financed by printing money, inflation is continuously lower under plausible conditions. When the government can borrow in world capital markets and layoffs reduce the present-value wage bill, there exists a sequence of bond sales and subsequent redemptions that guarantees continuously lower inflation. This result does not hold, however, if the reform lacks credibility.     

FTPL-Perspective on Tradable Deficit Permits in the EMU

The Growth and Stability Pact restricts member states in their fiscal policy but also causes inflexibility in the pursuit of wide-ranging economic and social reforms. Tradable deficit permits allow more flexibility for individual member states and provide a stick for those who exceed the deficit limit but also a carrot to those who stay below it. But does the trade in deficit permits affect the monetary objectives of the European Central Bank (ECB)? We argue that from a perspective of fiscal theory of the price level, trade in deficit permits can lead to higher inflation depending on the growth rate and the debt/GDP ratio of the member states.     

The Relationship between Federal Deficits and Real Interest Rates

Real interest rates fluctuated a great deal since the 1970s. In the 1980s federal deficits accelerated and their impact on both nominal and real interest rates gained lots of attention. Based on monthly and quarterly data from January 1971 to December 1997 it is found that federal deficits had significant positive effect on the real interest rates: Personal income or consumption are found to have significant positive impact on the real interest rates, whereas expected inflation and money supply are found to have negative impact on the real interest rates. These findings are consistent with the conventional economic theory.     

The impact of traffic sign deficit on road traffic accidents in Nigeria

This study assesses the impact of traffic sign deficit on road traffic accidents in Nigeria. The participants were 720 commercial vehicle drivers. While simple random sampling was used to select 6 out of 137 federal highways, stratified random sampling was used to select six categories of commercial vehicle drivers. The study used qual-dominant mixed methods approach comprising key informant interviews; group interviews; field observation; policy appraisal and secondary literature on traffic signs. Result shows that the failure of government to provide and maintain traffic signs in order to guide road users through the numerous accident black spots on the highways is the major cause of road accidents in Nigeria. The study argues that provision and maintenance of traffic signs present opportunity to promoting safety on the highways and achieving the sustainable development goals.     

芯片物理指纹的可用性评估

芯片物理指纹(Physical Unclonable Function,PUF）技术可用于构建新型可信认证体系,具有小型化、低功耗、高安全特性。通过对芯片物理指纹认证性能的研究,提出了对芯片物理指纹可用性相关概念的量化表征。基于芯片物理指纹实测数据进行了更多样本数据的模拟,分析了芯片物理指纹认证参数设置与安全性要求的关系,实现了对芯片物理指纹的可用性的有效评估,为芯片物理指纹技术进一步实现工程化应用提供了参考。     

解析美国巨额贸易逆差形成的原因

随着近年来经济全球化进程的加快,美国出现了全球所独有的巨额贸易逆差,并呈现出不断扩大的趋势,分析其贸易逆差形成的原因具有十分重要的现实意义。本文结合当今全球贸易的新特点,重点分析了美国制造业商品贸易的变化,指出美国信息产业等诸多产业已经转移到新兴工业化国家,尤其是亚洲国家。这种全球性的产业转移和技术扩散引致美国制造业国际竞争力下降是其巨额贸易逆差形成和扩大的主要原因。     

巨额贸易逆差下美国经济增长模式及对中国经济的影响

自20世纪90年代以来,美国在巨额贸易逆差下实行了经济持续增长。本文从金融角度详细分析了美国依据美元特殊的国际货币地位和外汇储备特征实行对全球的金融剥削;从产业角度探讨了新一轮全球产业分工重组背景下制造产业的国际转移、跨国公司内部贸易、美国独特的进口商品结构、油价上涨和美国能源产业政策对“悖论”解释的合理性;从宏观政策角度解析了美国“双赤字”并存的必然原因。本文认为,美元地位的不断下降使美国经济增长模式存在潜在危机,而美国对内外经济失衡的调整,势必对中美贸易、人民币汇率、中国外汇储备及内外经济平衡产生深远的影响。     

美元特权对美国贸易逆差的影响探析

美元特权的形成使贸易逆差成为输出美元的主要途径,并对贸易逆差起到了助长作用,集中表现在美元特权使美国维持着巨额贸易逆差而不受外汇储备短缺的制约和金融危机的威胁,却使其他追求美元储备的国家依靠贸易顺差和过度储蓄来摆脱不利处境,从而从供给和需求两个方面推动了美国贸易逆差的持续扩大。但贸易逆差的继续发展和未来的调整势必会影响美元特权地位的巩固,使世界经济特别是发展中国家的国际经济活动面临极大的风险。     

加拿大旅游服务贸易现状及中加旅游贸易发展

加拿大是世界主要旅游服务贸易国之一,但长期以来其旅游服务贸易对减少其服务贸易逆差的贡献不大.通过历史数据归纳分析了加拿大旅游服务贸易的特征及存在的问题,并分析指出形成这些问题的原因;在研究中国出境旅游的发展变化中探讨了中加旅游服务贸易合作发展的可能性;指出如果中加两国能够签订ADS协议,则将为减少加拿大旅游服务贸易和服务贸易逆差作出较大贡献.
