This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports).     

A hierarchy of lorenz curves based on the generalized tukey's lambda distribution

A hierarchy of Lorenz curves based on the generalized Tukey's Lambda distribution is proposed. Representations of the corresponding distribution and density function are also provided, together with popular inequality measures. Estimation methods are suggested. Finally, a comparison with other parametric families of Lorenz curves is established.     

General m-esttmators and applications to bounded influence estimation for non-linear regression

In this paper, we study the M-estimators in the case that λ_F:(β)=E_F:(φ(Z,β))=0 has more than one solution, We show that the numerical iterative procedures converge and that the resulting estimators are consistent and asymptotically normal. We apply them to the non-linear regression models, and then, we find an optimal M-estimate among those that have bounded gross error sensitivity.     

Bayesian Design of Special Type of Double Sampling Plans for Compliance Testing

Bayesian acceptance sampling plans, which utilize prior information on the process variation, can be employed as an alternative to conventional types of plans for taking decisions on the disposition of submitted lots. A special type of double sampling inspection plans by attributes with small acceptance numbers using Bayesian methodology is presented in this paper emphasizing its significance over small acceptance number single sampling plans. The procedures for designing such sampling plans for specified degree of discrimination which would ensure protection to the producer and consumer are discussed with illustrations under the conditions for the application of gamma-Poisson distribution.

喹乙醇对斑点叉尾(鱼回)鱼种生长的影响

用3种不同剂量(30μg/g、100μg/g、200 μg/g)的喹乙醇饲料组和一个对照组对一冬龄斑点叉尾倒鱼种进行30d的饲养试验。结果表明:斑点叉尾(鱼回)鱼种平均尾增重以100μg/g组最高:其饲料系数最低,为2.31;耐低氧试验表明,100μg/g组最强,半致死浓度时间为3.25 h和3.19h;血糖测定表明:100μg/g组血糖含最最高,为201.15 mg/100ml;血红蛋白测定表明:各组血红蛋白很接近。     

1990年以来的日本经济增长分析

日本进入20世纪90年代之后,经济长期不振陷入爬行增长状态。通过国民收入支出法的量化分析,说明内需严重不足,特别是民间投资部门的增长率和贡献度都呈负值。尽管公共部门和国际贸易部门在经济增长中起到了一定的积极作用,但由于泡沫经济崩溃的影响和多年来积累的结构性矛盾的解决需要时间,所以直到21世纪初日本经济仍未能摆脱长期萧条的状态。     

对称性在定积分中的应用

对称性在定积分中的应用孙军安，郑德印利用函数图形的对称性可简化定积分的计算。在特殊情况下，甚至可以求出原函数不是初等函数的定积分。因此掌握用对称性计算定积分的方法是必要的有益的。本文首先给出一个引理，由此得出一系列有趣的结果，并通过实例说明这些结果的...     

国际资本流动冲击有利于经济增长吗

本文估算并应用潜在产出描述经济增长,尝试从国际合作角度设定动态结构面板向量自回归模型,识别自发性国际资本流动的综合性结构冲击,并进一步分解为共同冲击和特有冲击,提出研究国际资本流动冲击对经济增长影响的计量思路,以金砖国家为例进行实证分析。研究发现：国际资本流动冲击对金砖各国经济增长的效应因资本账户开放进程而异,但对金砖整体经济增长存在正效应,且不为金砖各国之间的资本流动冲击所扰;将金砖国家视为以国际合作形式联合的整体进行计量分析是可行且有经济意义的。中国应推进包括金砖国家在内的全方位南南合作,不断完善资本账户开放条件,分散国际资本流动冲击并使其有利于长期共同发展。     

Examining the Impact of Demographic Factors on Air Pollution

This study adds to the emerging literature examining empirically the link between population size, other demographic factors and pollution. We contribute by using more reliable estimation techniques and examine two air pollutants. By considering sulfur dioxide, we become the first study to explicitly examine the impact of demographic factors on a pollutant other than carbon dioxide at the cross-national level. We also take into account the urbanization rate and the average household size neglected by many prior cross-national econometric studies. For carbon dioxide emissions we find evidence that population increases are matched by proportional increases in emissions while a higher urbanization rate and lower average household size increase emissions. For sulfur dioxide emissions, we find a U-shaped relationship, with the population-emissions elasticity rising at higher population levels. Urbanization and average household size are not found to be significant determinants of sulfur dioxide emissions. For both pollutants, our results suggest that an increasing share of global emissions will be accounted for by developing countries. Implications for the environmental Kuznets curve literature are described and directions for further work identified.
