Equilibrium Dynamics in an Endogenous Growth Model of Money and Banking

We construct an analytically tractable endogenous growth model of money and banking where money provides "liquidity services" to facilitate transactions and banks convert non-reserve deposits into productive capital. We examine both the long- and short-run effects of changes in the money growth rate or the reserve requirement ratio. In response to a change in the required reserve ratio, the inflation rate and the growth rates of capital, real balances, and consumption need not adjust monotonically along the transition path. While the balanced growth equilibrium may be either a saddle or a source locally, the global dynamical system exhibits flip bifurcation.     

公路计重收费下运输企业的发展对策探讨

目前，我国不仅是高速公路实施了计重收费政策，也有省在一般公路采用计重收费。对比计重收费前后高速公路通行费的变化情况，分析公路货运行业运输价格的变化情况、运输装备的发展方向，以及对公路运输模式和货运企业管理体制的影响，在公路计重收费条件下，我国运输企业如何有效地应对计重收费带来的影响，并在计重收费条件下更好更快地发展。     

基于DEA模型的我国渔业生产效率的研究

文章运用非参数的DEA（数据包络分析）模型,对我国31个地区的渔业生产效率进行实证研究,结果表明：我国部分地区渔业生产效率走在全国前列,大部分地区表现为粗放型的技术进步特征,生产效率始终在较低水平徘徊,综合效率有待进一步提高。各省在渔业生产要素投入上应当根据实际情况合理搭配避免投入过多造成资源浪费、不可持续发展。     

基于自组织理论的供应链协同管理

实现节点企业之间的协同发展是供应链管理的核心目标,而自组织原理又作为协同学中的核心内容,能为供应链的协同发展提供重要的理论支撑。正是以自组织理论为研究出发点,根据自组织演化的一般规律特点,再结合供应链管理的系统特性,深入地分析了供应链如何通过自组织进程来实现协同管理目标的基本过程,对于供应链协同管理能起到一定的理论借鉴作用。     

智慧引导 爱心驱动任吉忠的爱维艾夫梦之队

凡是中国的优秀企业家,骨子里总有儒家的基因和情结。过去有人说儒家文化不利于商品经济,其实“兼善天下”的意义并不亚于韦伯的“新教伦理”。任吉忠的爱维艾夫的立业理念为“崇尚功德”,正是儒家的“三不朽”之一——“立德”。     

DUALITY WITH SECTOR‐SPECIFIC EXTERNALITIES UNDER SOCIAL CONSTANT RETURNS*

We develop dual approaches to quantity and price relationships of production in a general multisectoral model with sector‐specific externalities. The production of each good exhibits socially constant returns to scale but privately decreasing returns. We find that the Stolper‐Samuelson theorem holds for factor intensity ranking from the social perspective and that the Rybczynski theorem holds for factor intensity ranking from the private perspective. The price‐output dual fails to hold in general. Moreover, we re‐establish the Heckscher‐Ohlin theorem in the two‐sector case, as well as the factor endowment–factor price and price‐output comparative statics in the high‐dimension case under proper conditions.     

A Bargaining Model of Auditor Reporting*

In this paper, I demonstrate that the quasi-rents earned in audits undermine an auditor's independence By considering the incentives of the auditor and the client and the interaction between them, I conclude that auditor will maintain his or her independence if the firm-specific quasi-rents are zero, but compromise his or her independence if the quasi-rents are positive. The extent of the compromise is an increasing function of the quasi-rents, since the auditor will propose that a higher value be reported in the financial statements when the quasi-rents increase. I also show that disputes between the auditor and the client increase as the scope for errors for an auditor's test increases. When the error scope is large, the client becomes more aggressive in preparing a proposal while the auditor becomes more cautious.     

吸引外商投资的新思路

本文从五个方面谈了我国在吸引外商投资方面应调整的思路，一是从直接投资方式到多渠道的间接投资方式，二是从兴办三资企业到外资并购、BOT等新形式，三是从重视引资规模和数量到重视引资结构和质量，四是从依靠政策优惠吸引外资到营造综合投资环境吸引外资，五是从东南沿海吸引外资到外资西进。     

DO AFRICAN COUNTRIES MOVE ASYMMETRICALLY TOWARDS PURCHASING POWER PARITY?

This paper investigates the possibility that the adjustment towards long‐run relative purchasing power parity (PPP) is dependent upon the nature of deviations from PPP that are experienced. While existing studies involving developed and less developed countries often find against PPP having employed linear tests of non‐stationarity or non‐cointegration, we employ a new cointegration test, recently advocated by Enders and Siklos and Enders and Dibooglu, that tests for an asymmetric adjustment towards parity with respect to positive and negative deviations of the real exchange rate from its equilibrium value. Using a sample often African economies with data taken from the post‐Bretton Woods floating exchange rate era, long‐run PPP holds in eight of these cases if an explicit distinction is made between positive and negative deviations. Across the sample, we find variation in the type of asymmetry experienced and the roles played by price and nominal exchange rate adjustment.     

“张杂谷”系列谷子品种淀粉含量的分析与评价

对不同产地的"张杂谷"品种谷子的直链和支链淀粉含量、胶稠度、碱消值进行了分析,运用双波长法同时测定谷子中直链淀粉和支链淀粉的含量。结果显示,直链淀粉含量、胶稠度和碱消值均因品种和产地不同而有差异。不同产地的4个品种谷子直链淀粉含量平均为14.46%(质量分数,下同),总淀粉含量平均为71.73%,胶稠度为9.1%～16.3%,碱消值为2.8～3.4。结果初步表明,"张杂谷"系列谷子具有较好的食味品质。
