An estimation of returns to scale of airport airsides under multiple optimal solutions in DEA

The returns to scale (RTS) nature of 37 Chinese airport airsides are investigated in this paper. Multiple optimal solutions in DEA (Data Envelopment Analysis) models may lead to error RTS estimation. To address this problem, we use the (Zhu and Shen, 1995) RTS method. The empirical study shows that all those airsides with two runways operate under decreasing RTS and those airsides with only one runway either operate in the area of increasing RTS or in the area of constant RTS.     

耦合产业系统中资源与污染的结构性动态分析

可持续的产业发展分析往往关注于经济增长与资源、环境之间的互动影响,以及它们在最优增长路径上的动态分配过程,一般很少考虑产业依赖的资源与产业发展中环境诸要素(如衰减能力、环境本底值等)的背景条件不同而引发的耦合产业结构和规模的问题[1-14]。本文主要对基于资源消耗和可持续发展框架下耦合产业系统的最优化增长路径上产业结构的动态变化进行刻画和模拟实证。数值模拟显示,对于可持续的耦合产业系统长期发展而言,两个产业的结构和规模将随着环境诸要素动态变化,随之产生的社会效益和环境损害也是动态变化的。而且,资源的消耗水平、耦合产业中各子产业的发展结构、环境条件将影响到耦合产业系统的最优增长路径,在特定的情况下将出现类似于Kuznets曲线性状的拐点。     

Subnational institutional environment,scale competition and MNEs’ ownership levels in transition economy: evidence from China

Abstract

This paper shows that the effect of market scale competition on the ownership levels of foreign-funded enterprises is conditioned on sub-national institutional environment in China. Analysis is based on the idea that multinational enterprises subject to the dual pressures of institutional isomorphism and competition in the host country. The provincial panel data from 2001 to 2012 is used for empirical tests. This study indicates that the weaker the legal property rights protection and legal enforcement of contracts, and the higher the opening up, the more the large foreign-funded enterprises decrease their ownership levels, whereas the negative moderating effect incurred by the reduction to government intervention in business is limited significant.     

The effect of firm scale and CSR geographical scope of impact on consumers' response

The role of corporate social responsibility (CSR) in shaping consumer perception and attitude has received many attentions both in the academia and practitioner world. While this domain has invited numerous research, but research highlighting how consumers react toward learning the size of a firm conducting CSR and geographical scope of the CSR impact is still scarce. We investigate how consumers shape their attitude and consumption behavior after knowing that the CSR action is done by a small, locally-owned business that brings impact to the local community through an experimental study. Our study adds a shade in understanding how the effect of a firm size and geographical scope of CSR impact might increase consumers' favorable attitude and behavior toward the business and its products. Our findings show that when consumers learn that the firm conducting CSR is a small, locally-owned (in coffee shop business) that directs its action toward local beneficiaries, they demonstrate more favorable attitudes toward the action and the firm, which manifest in the form of better intentions to acquire the product as well as willingness to pay premium prices for it. Our findings confirm the US consumers' love affair with local businesses, in particular. While the findings generally benefit small, locally-owned businesses, they also suggest recommendations for large, multinational businesses to design their marketing strategy in an attempt to increase favorable reactions from consumers.     

论《新装》中女主人公梅布尔矛盾的双重性格

《新装》是英国著名意识流小说家弗吉尼亚.伍尔夫的短篇小说之一,小说刻划了女主人公梅布尔矛盾的双重性格特征：既爱慕虚荣又渴望诚实,既自卑绝望又充满希望,既羡慕嫉妒又厌恶憎恨,既懦弱多变又勇敢坚强,既追求个性又迷失自我。从她矛盾的双重性格特征中可以看出人的本性及弱点。     

Sequential estimation of a location parameter and powers of a scale parameter from delayed observations

The problem of sequentially estimating a location parameter and powers of a scale parameter is considered in the case when the observations become available at random times. Certain classes of sequential estimation procedures are derived under an invariant balanced loss function and with the observation cost determined by a convex function of the stopping time and the number of observations up to that time.

国有产权安排和国有经济规模内生性研究

运用马克思经济学关于生产力决定生产关系的基本理论和杨小凯发展的斯密-科斯框架的交易费用理论分析所有权安排的演进的内生性决定因素,得出其结论:一种所有权安排是技术变迁和制度变迁相互作用的结果。用内生交易费用和外生交易费用分别来刻画一个特定时点上制度条件和技术条件的现实状况,说明一个时期的内生交易费用和外生交易费用的分布可以决定这个时期的所有权安排。     

Are some Indian banks too large? An examination of size efficiency in Indian banking

In this paper we use data from the years 1997–2003 to evaluate the size efficiency, as distinct from scale efficiency, of Indian banks. Following Maindiratta [Maindiratta A (1990) J Econ 46:39–56] we consider a bank to be “too large” if breaking it up into a number of smaller units would result in a larger output bundle than what could be produced from the same input by a single bank. When this is the case, the bank is not size efficient. Our analysis shows that many of the banks are, indeed, too large in various years. We also find that often a bank is operating in the region of diminishing returns to scale but is not a candidate for break up.
