微波反馈放大器匹配及增益带宽的研究

本文介绍的是小信号微波反馈放大器的分析与综合。放大器是采用通常的增益级的框图,并取并联反馈。文中提供全部网络元件值的估算和预测闭环宽频带增益、带宽和双端口的匹配值。简述匹配值与增益用图解法的权衡。最后描述了综合方法并举例说明设计实例。     

Has Germany Been Europeanised or Has Europe Become (too) Germanic?

It has often been argued that European monetary unification must basically be seen as a device to Europeanise re-unified Germany. For the Germans it seemed to be the best possible way to prevent a German “Sonderweg” and end any German ambition for hegemony. For the rest of Europe, and particularly France, it seemed to be the best way to curb German monetary dominance and to secure a French imprint on EU policy-making. In this article, however, it is argued that the German impact on the economic governance regime of EMU and its fencing off the French proposal of a “gouvernement economique” is so substantial that the term “Germanic Europe” seems in fact to be appropriate. More importantly, the economic governance system of “Germanic Europe” has locked the European Union into a politics of disinflation which makes it difficult for the EU to prosper and reap the potential fruits of European integration.

解非线性电路稳态响应的一种有效算法

本文提供一种计算非线性电路的稳态响应的有效算法,在多频信号激励的强迫振荡电路和耦合振荡电路都可使用。该方法可称为“代换算法”。因为,它每一步的变量都是用残留误差的各个频率分量解关联时不变电路,该电路是用“松弛法”将时变电路转换而来。此算法非常简单而有效,并且可应用于各种非线性电路。     

Minimum wage,trade and unemployment in general equilibrium

The path‐breaking work of Card and Krueger, showing that a higher minimum wage can increase employment, turned the age‐old conventional wisdom on its head. This paper demonstrates that this apparently paradoxical result is perfectly plausible in a competitive general equilibrium production structure of a small open economy with a non‐traded good, without recourse to monopsony, spatial heterogeneity, heterogeneity of consumers and so on, the usual theoretical drivers behind the result. Following Jones and Marjit, we build a simple general equilibrium model with production complementarity and we show that a higher minimum wage can raise aggregate employment. Expansion in the non‐traded sector following a wage hike may be consistent with the overall expansion of the export sector in a multi‐good framework, an unlikely outcome in a conventional two‐good model which cannot accommodate with production complementarity.     

安全联盟与经济合作研究——基于四种联盟类型的分析

联盟建立的初衷是为了满足国家在安全上的需要。但在无政府状态的国际社会中,经济交往产生的安全外部性促进了结盟国家间贸易往来的增加,确保了联盟国家间经济交往的发展;在联盟建立和发展过程中,联盟框架内存在的议题联系机制为联盟国家之间进行安全合作的同时实现经济合作提供了相应的交往渠道和方式。同时,一国通过经济上的补偿性支付的方式向其盟国提供经济补偿,使其从经济上获益,从而确保了安全联盟的稳定。根据联盟成员间的相互依存度和利益相容性程度,联盟会表现为实力增强型联盟、协调型联盟、霸权型联盟和飘忽不定型联盟等四种类型,联盟经济在各种类型的联盟中都会发挥作用;但在不同类型的联盟中,由于上述两个变量的不同,经济合作与安全利益的关联程度会有不同的表现,补偿性支付也会发挥不同的作用。     

The Demand for Money in Canada: A Cointegration Analysis

In this Paper, using the techniques in cointegration theory, we find strong support for the existence of a long-run equilibrium relationship among money demand variables in Canada. Additionally, when the conventional partial adjustment model (PAM) is compared to the two-stage error correction model (ECM), the latter approach is found to perform better, with M2+ showing better results than M2. Our results are also found to be in line with other studies from the U.K. and the U.S.A. These findings provide rationale for further in-depth studies on broader monetary aggregates to formulate sound monetary policy in Canada. [E41]     

Foreign Management,International Capital,and Income Redistribution

This paper examines the impact of foreign management as a separate input in a competitive economy open to both international trade and international movement of productive capital. Three inputs (capital, labor, management) are used to produce two final goods in a model characterized by competition, homogeneous products, and full employment. This model provides a simple starting point for the study of multinational firm activity, building on the fundamental competitive factor proportions model of production and trade. A clear distinction arises between international movements of capital and management, and international movements of the two inputs are linked. [F 11, F 23]
