经验收入曲线:生产力还是制度作用?——高校教师收入的经验分析

经验收入曲线向上倾斜的原因是人力资本理论中教育、培训带来的较高生产力还是其他制度因素?由于个人产出品衡量上的困难,文章选择学术劳动力市场作为研究对象,利用M incer(1979)的经验收入方程对中国某一高校教师收入进行经验分析,结果验证了人力资本理论的同时并不排除制度因素的作用,在其他条件不变的情况下,经验对收入大于产出对收入的影响;教师职称对收入有较大的影响。

阻碍资本外流契约对区域经济的影响

阻碍资本外流契约不仅影响资本优化配置,也削弱代理人在优惠回报契约中的谈判力,从而使区域经济难以实现效用最大化.同时,在存在代理人道德风险的情况下,阻碍资本外流契约所规定的撤资高额违约金会妨碍区域经济总效用最大化的实现.应从制度上消除区域内外资本的等级差别,规定区域融资契约合理的法定有效期,并制定强有力的法律来制止区域融资主体迫使投资者与之签订只体现自己意愿的阻碍资本外流契约.

A DEA Approach to Understanding the Productivity Growth of Malaysia's Manufacturing Industries

This paper seeks to explain the productivity growth performance of Malaysia's manufacturing sector using a panel data of 28 industries from 1981–1996. Here, the data envelopment analysis technique is used to calculate and decompose the Malmquist index of total factor productivity (TFP) growth into technical change, change in technical efficiency and change in scale efficiency. This allows the identification of the sources of productivity growth which is crucial for policy formulation. It was found that the annual TFP growth of the Malaysian manufacturing sector was low at 0.8% and this was driven by small gains in both technical change and technical efficiency, with industries operating close to optimum scale.     

75kW中频感应加热电源的研制

针对中频感应加热电源对油田油井加热问题,本文采用PWM控制技术实现了功率可调。为使系统的功率因数较高,采用串联谐振和频率跟踪技术。中频感应加热电源采用IGBT作为开关器件,可工作在10 Hz-10 kHz频段。它充分利用中频趋肤效应、邻近效应和圆环效应原理,通过感应加热器和油管柱,使电能有效的转化为热能,从而达到原油降粘降稠、稳产高产的目的。

Productivity and Technical Change in Malaysian Banking: 1989–1998

This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.JEL classification: D24, G21This paper was written while Dogan was a member of Monash University Malaysia.
