边疆民族地区经济增长与就业关系比较研究

通过建立GDP就业模型揭示经济增长与就业的内在关系。要增加就业降低失业率，必须保持快速和稳定的经济增长和提高GDP就业弹性。比较分析边疆少数民族地区和东部发达地区的GDP就业弹性，发现由于东部发达地区经济更依赖于资本和技术进步，其GDP就业弹性、GDP对就业的“指数效应”比边疆少数民族地区的小。同时随着边疆少数民族地区经济的资本有机构成逐渐提高和进一步的资本深化，GDP就业弹性也在逐渐下降。东部发达地区GDP对就业的“乘数效应”比边疆民族地区的大，说明了东部发达地区依然是吸收就业和农村剩余劳动力的主要地区，并提出增加就业的对策建议。     

投入产出乘数模型与其扩展方法

在投入产出模型里引入凯恩斯乘数理论，建立能够计算结构化乘数的投入产出乘数模型，是近年来投入产出领域探讨较多的一个问题。从前提假设、乘数效应的传导机制和最终推导结果等方面对凯恩斯乘数模型和投入产出乘数模型进行比较，指出建立投入产出乘数模型将凯恩斯乘数进行结构化处理，应该从放宽前提假设条件入手，并以引入列向旁侧效应为例对原模型进行了扩展。     

论专利产品平行进口问题的法律实质

专利产品平行进口问题的法律实质在于物权和专利权谁优先保护的问题。从竞争法角度来探索权利用尽原则和地域性原则的理论冲突将为我国专利产品平行进口的相关立法提供有益的思路。     

电子货币的发展对日本货币政策有效性的影响

日本作为亚洲成熟金融货币体系的代表,电子货币的迅速发展及其对货币政策的影响效果是值得我们探讨和借鉴的.基于巴塞尔委员会对电子货币的定义,日本银行按年度发布了2007～2008财年的电子货币及其他货币供给数据.借助这些数据,可以检验近两个财政年度日本电子货币的发展对日本央行货币政策有效性是否产生值得关注的影响,即日本电子货币的替代效应对央行的各层次货币乘数是否产生显著的影响,以及日本银行的电子货币发展状况调查结果与结论能否指引央行有效地制定和实施在电子货币条件下的货币政策.

A hybrid parallel genetic algorithm for yard crane scheduling

This paper aims at postulating a novel strategy in terms of yard crane scheduling. In this study, a dynamic scheduling model using objective programming for yard cranes is initially developed based on rolling-horizon approach. To resolve the NP-complete problem regarding the yard crane scheduling, a hybrid algorithm, which employs heuristic rules and parallel genetic algorithm (PGA), is then employed. Then a simulation model is developed for evaluating this approach. Finally, numerical experiments on a specific container terminal yard are used for system illustration. Computational results suggest that the proposed method is able to solve the problem efficiently.     

Distribution of parallel exchange rates in African countries

This paper investigates the distribution of parallel exchange rates in African countries using exploratory data analysis techniques and model fitting. Stable laws are fitted to empirical distributions using the maximum likelihood estimation method. Empirical evidence supports the stable hypothesis these distributions are positively skewed and have tails that are much heavier than Gaussian counterparts. The stable hypothesis is further supported by the “converging variance test,” which suggests that these distributions have infinite variance.     

Why parallel trade may raise producers' profits

This paper shows that a manufacturer may benefit from parallel trade. In addition to an intuitive condition about the effect of demand shocks, this occurs when competitive retailers must order inventories before they know the realization of demand and for products whose sale value drops at the end of the demand period. For these types of products, letting retailers trade unsold inventories generally results in larger orders placed with the manufacturer and higher manufacturer profit. The model provides a simple explanation as to why the volume of parallel trade is now very large and accepted by manufacturers for some products such as automobiles, clothes, toys, consumer electronics, musical recordings, cosmetics and perfumes.
