浅析中国股市政策性依赖减弱的原因

文章从投资者的风险偏好角度出发,分析中国股票市场从特征明显的“政策市”到政策性依赖趋于减弱的原因。通过研究单一代表性经济人的单期模型发现,在投资者风险厌恶程度较低时,由政策因素引起的预期股票收益率的变化而带来的股市变化幅度较大;随着投资者结构以及投资理念的转变,投资者的风险厌恶程度明显加大,导致政策因素变化对股票市场的影响幅度大大减弱。     

The water footprints of Morocco and the Netherlands: Global water use as a result of domestic consumption of agricultural commodities

The volume of international trade in agricultural commodities is increasing faster than the global volume of production, which is an indicator of growing international dependencies in the area of food supply. Although less obvious, it also implies growing international dependencies in the field of water supply. By importing food, countries also import water in virtual form. The aim of the paper is to assess the water footprints of Morocco, a semi-arid/arid country, and the Netherlands, a humid country. The water footprint of a country is defined as the volume of water used for the production of the goods and services consumed by the inhabitants of the country. The internal water footprint is the volume of water used from domestic water resources; the external water footprint is the volume of water used in other countries to produce goods and services imported and consumed by the inhabitants of the country. The study shows that both Morocco and the Netherlands import more water in virtual form (in the form of water-intensive agricultural commodities) than they export, which makes them dependent on water resources elsewhere in the world. The water footprint calculations show that Morocco depends for 14% on water resources outside its own borders, while the Netherlands depend on foreign water resources for 95%. It is shown that international trade can result in global water saving when a water-intensive commodity is traded from an area where it is produced with high water productivity to an area with lower water productivity. If Morocco had to domestically produce the products that are now imported from the Netherlands, it would require 780 million m³/year. However, the imported products from the Netherlands were actually produced with only 140 million m³/year, which implies a global water saving of 640 million m³/year.     

新疆国内游客综合满意度影响因子及发展对策分析

从旅游业各组成要素的角度,运用灰色综合关联度分析法以及满意度四分图模型对影响新疆国内游客综合满意度的主导因子及其影响力的大小进行了探讨。研究结果表明,各因子对综合满意度的影响程度存在明显差别,可分为三个层次:长途交通、景区游览的满意度与综合满意度的关联度最高,在0.9以上,是目前影响新疆国内游客综合满意度的关键因子;购物和导游是主要因子,关联度在0.8以上;而娱乐、餐饮和住宿的关联度最低,是次要因子。因此,今后应把重点放在各类交通的发展和景区的建设和提高上。处于提升区的购物和导游是目前新疆旅游业发展急待改进的因子,也是新疆国内游客满意度提高的关键所在,要加大对这两方面的投入,争取在短时间内提高服务水平,改善购物环境,以扩大国内旅游客源市场份额。     

Oblivious equilibrium for concentrated industries

This article explores the application of oblivious equilibrium (OE) to highly concentrated markets. We define a natural extended notion of OE, called partially oblivious equilibrium (POE), that allows for there to be a set of strategically important firms (the “dominant” firms), whose firm states are always monitored by every other firm in the market. We perform computational experiments that explore the characteristics of POE, OE, and Markov perfect equilibrium (MPE), and find that POE generally performs well in highly concentrated markets. We also derive error bounds for evaluating the performance of POE for cases where MPE cannot be computed.     

An Application of the Dynamic Network DEA Model: The Case of Banks in Taiwan

ABSTRACT

In this study, we apply the dynamic network slack-based measure data envelopment analysis model (DNSBM) to measure the efficiency of Taiwanese banks during the period 2005–11. Using the network structure, we define intellectual capital creation capability as one of the production stages. In order to capture the dynamics of the transformation process, the nonperforming loans and loan loss reserves are defined as carryover items. This study offers sufficient information for managers to understand not only the overall performance of their banks but also the efficiency of each production stage and the dynamic changes of the overall and divisional efficiencies.

An Empirical Analysis of Synthesizing the Effects of Festival Quality,Emotion, Festival Image and Festival Satisfaction on Festival Loyalty: A Case Study of Macau Food Festival

This study aims to examine the interrelationships among the festival quality dimensions, festival quality, emotion, festival image, festival satisfaction and festival loyalty. Analysis of data from 454 attendees in the 12^th Macau Food Festival indicates that the proposed model fits the data. The result of this study will assist festival management in developing and implementing market‐orientated service strategies to increase quality and image, and enhance the emotion and satisfaction of attendees in order to attain their loyalty toward food festivals.

Celebrity Attachment and Behavioral Intentions: The Mediating Role of Place Attachment

Film‐induced tourism has recently gained increased attention in academic research. Although previous literature has identified the existence of consumer–celebrity attachment, scant empirical studies have examined whether celebrity attachment influences behavioral intentions in a film tourism context. The purpose of this study is to examine the relationship between celebrity attachment and behavioral intentions as well as to clarify the role of place attachment. Survey data from 312 tourists in Taiwan indicate that celebrity attachment is positively related to behavioral intentions. Moreover, place attachment partially mediates the relationship between celebrity attachment and behavioral intentions. Implications of these findings for managing marketing strategies as well as future research directions are subsequently discussed. Copyright © 2013 John Wiley & Sons, Ltd.
