Summary The exact mean square error for the ratio estimator of a finite population total based on simple random sampling without replacement
is shown to have an expected value less than that of the variance of the ratio estimator based on Midzuno’s scheme, under
a usual super-population model. 相似文献

The paper reexamines the conventional results relating to inflow of foreign capital, removal of protectionism and structural reform programmes, in a small open economy in terms of a two-sector general equilibrium model with an informal sector. The paper shows that in the presence of labour market distortion and a protectionist policy, inflow of foreign capital may be desirable irrespective of the pattern of trade of the economy due to its favourable impact on welfare. But the welfare implications of tariff reductions and/or structural adjustment programmes, such as deregulating the formal sector labour market, depend crucially on the economy's trade pattern. The paper provides an answer to the question as to whether in a developing economy labour market reform and tariff reform should go hand-in-hand or whether one should precede the other for welfare improvement.

中国和印度不平衡发展的比较研究 总被引:3,自引:0,他引:3
本文考察了中国和印度近年来经济增长不平衡的情况,并分析了不平衡增长对不均等和贫困的影响。通过对家庭调查数据和官方加总数据的分析,本文发现增长存在不平衡——区域间、产业间和家庭层面上,这表明减贫工作进展不平衡,若增长更平衡,减贫效果可能更好;另外,收入不均等程度也在提高。本文探讨了增长不平衡及其应引起重视的原因。具体讨论围绕"有利的"和"不利的"不均等两个概念展开——不均等与不平衡增长对公平性以及长期增长与发展的有利或不利影响。我们认为,需要制定相关政策,保持有利的不均等——继续鼓励创新和投资,同时降低不利的不均等的程度,尤其是通过人力资本和农村基础设施投资,帮助贫困人口参与市场。 相似文献

Sustaining cooperation in laboratory public goods experiments: a selective survey of the literature 总被引:5,自引:0,他引:5
Ananish Chaudhuri 《Experimental Economics》2011,14(1):47-83
I survey the literature post Ledyard (Handbook of Experimental Economics, ed. by J. Kagel, A. Roth, Chap. 2, Princeton, Princeton
University Press, 1995) on three related issues in linear public goods experiments: (1) conditional cooperation; (2) the role of costly monetary
punishments in sustaining cooperation and (3) the sustenance of cooperation via means other than such punishments. Many participants
in laboratory public goods experiments are “conditional cooperators” whose contributions to the public good are positively
correlated with their beliefs about the average group contribution. Conditional cooperators are often able to sustain high
contributions to the public good through costly monetary punishment of free-riders but also by other mechanisms such as expressions
of disapproval, advice giving and assortative matching. 相似文献

We consider efficient estimation in moment conditions models with non‐monotonically missing‐at‐random (MAR) variables. A version of MAR point‐identifies the parameters of interest and gives a closed‐form efficient influence function that can be used directly to obtain efficient semi‐parametric generalized method of moments (GMM) estimators under standard regularity conditions. A small‐scale Monte Carlo experiment with MAR instrumental variables demonstrates that the asymptotic superiority of these estimators over the standard methods carries over to finite samples. An illustrative empirical study of the relationship between a child's years of schooling and number of siblings indicates that these GMM estimators can generate results with substantive differences from standard methods.

The paper deals with a production inventory model for various types of items where multiple suppliers, a manufacturer and the multiple non-competing retailers are the members of the supply chain. In this model, each supplier supplies only one type of raw material to the manufacturer. The manufacturer produces a finished item by the combination of certain percentage of the various types of raw materials. The manufacturer produces also multi-items and delivers them according to the demand of the different retailers. Finally, an integrated profit of the supply chain is optimized by optimal ordering lot sizes of the raw materials. A numerical example is provided to justify the proposed model. 相似文献

The effects of media, product and advertising strategy variables on consumers' thoughts and feelings are investigated. Both direct and indirect paths from the advertising variables to ad persuasiveness measures are also analysed with the indirect paths leading through affective and cognitive responses. Two hundred and forty television and magazine ads are analysed with respect to advertising variables, affect, cognition and ad persuasiveness. Results indicate that advertising variables are indirectly linked to ad persuasiveness with the indirect path occurring through affective and cognitive responses. 相似文献

In a two‐country model where firms behave à la Cournot, we show that trade liberalization increases (decreases) the social desirability of those mergers that generate sufficiently large (small) reductions in marginal cost. There exists a range of intermediate levels of marginal cost savings such that marginal tariff reductions increase (decrease) the desirability of merger at sufficiently low (high) tariff levels. Moreover, in the neighborhood of free trade, we show that if trade liberalization increases the profitability of a merger, it necessarily also increases its desirability. 相似文献

The objective of this paper is to develop a multi-echelon supply chain model for multiple-markets with different selling seasons. Here, two suppliers are involved to supply the raw materials to the manufacturer where the main supplier may face supply disruption after a random time and the secondary supplier is perfectly reliable but more expensive than the main supplier. In this article, the manufacturer produces a random proportion of defective items which are reworked after regular production and are sold in a lot to another market just after completion of rework. The retailer sells the finished products in different markets according to seasons. Finally, an integrated expected cost per unit product of the chain is minimized analytically by considering the lot-size ordered as a decision variable. An appropriate numerical example is also provided to justify the proposed model. 相似文献

In the retail domain, we consider the moderating influence of shopper experience (high versus low experience) and store type (high- versus low-priced stores) on a model that identifies three distinct routes (economic, affective and informational) from perceived merchandise value to willingness to pay a higher price. Each route accounts for a different outcome arising from merchandise value and leading to willingness to pay a higher price. Analyses of data obtained from a sample of 600 shoppers at four grocery stores provide results for specific hypotheses related to each moderator and each distinct route. The results of multiple sample analyses show that the economic route is stronger for high experience shoppers as well as for high-priced stores. Findings pertaining to hypotheses for moderation of both the affective and informational routes are mixed. We discuss the importance of these findings for retail managers as well as for future research. 相似文献
