Hedonic price indices for the Paris housing market

Summary: In this paper, we calculate a transaction–based price index for apartments in Paris (France). The heterogeneous character of real estate is taken into account using an hedonic model. The functional form is specified using a general Box–Cox function. The data basis covers 84 686 transactions of the housing market in 1990:01–1999:12, which is one of the largest samples ever used in comparable studies. Low correlations of the price index with stock and bond indices (first differences) indicate diversification benefits from the inclusion of real estate in a mixed asset portfolio.*This paper has been developed at the Research Program Real Estate Finance at Goethe-University of Frankfurt/Main (Germany).

电影翻译的动态观——中国电影翻译考察

综观我国电影翻译的历史,我们发现,无论是翻译数量的多寡还是翻译方式的变革都始终与社会的发展及受众审美观念的变化联系在一起.有理由认为,电影翻译应当与时代、受众的接受程度、理解水平以及他们的精神需求相适应,它不应该是一成不变的,而应该是一个动态发展的过程.本文从我国电影翻译的历史、现状、观众需求等方面进行考察,提出我国电影翻译应当在提高译制质量的同时走多元化的道路.     

中国现当代文学批评观批判

中国现当代文学批评观经历了从进化论文学批评观下的多元化批评,到以现实主义模式独尊的阶级（政治）论文学批评观,再到以社会政治为主导的多元并存的文学批评观的曲折变化历程。这一具有开创性的理论化层次的文学批评道路,有着历史历程碑的重要意义。但这种严重倾斜到非文学的社会立场之上的文学批评观,在文学与社会的基本关系上是颠倒、错位的,导致了一系列批评观念的偏误,需进行严肃的辨析和批判。     

企业多元化经营与企业绩效关系分析模型

通过分析企业多元化与企业生产成本和协调成本的关系,构建了企业多元化对企业绩效影响的分析模型,并得出相关结论：相关多元化经营既能提高企业绩效也能降低企业绩效,适度的相关多元化经营能使企业实现范围经济,提高企业绩效 过度的相关多元化经营将使企业出现范围不经济,降低企业绩效。非相关多元化会降低企业经营绩效。多元化经营企业产品关联度与企业绩效提高成正比,关联度越高,越能提高企业绩效。现代信息技术的广泛使用,增加了企业实行多元化经营的动力。     

大学英语教学“中国文化失语症”及其对策研究

通过对江南大学非英语专业大学生对中国本土文化英语表达能力的调查发现,当前多元文化环境下的大学英语教学中存在本土文化缺失问题,并由此导致学生跨文化交际中频显“中国文化失语症”。建议提倡“生产性多元文化主义”,培养学习者的“文化多面性”和“文化创造力”以及本土文化信息源多样化等措施,以强化在大学英语教学中本土文化教育的重要性。     

Mitigating Supply Uncertainty: The Interplay Between Diversification and Pricing

We consider a firm's sourcing problem from one reliable supplier and one unreliable supplier in two price‐setting scenarios. In the committed pricing scenario, the firm makes the pricing decision before the supply uncertainty is resolved. In the responsive pricing scenario, the firm's pricing decision is made after the supply uncertainty is resolved. For the committed pricing scenario, we develop a condition on supply uncertainty that guarantees the unimodality of the firm's objective function. By comparing the firm's optimal diversification decisions in the two pricing scenarios, we examine the interplay of supply diversification strategy and responsive pricing strategy in mitigating supply uncertainty. While both strategies are effective in mitigating supply uncertainty, we show that they are not necessarily substitutes. The relationship between these two strategies depends on two adverse effects caused by supply uncertainty: the lost‐revenue effect and the lost‐goodwill effect. More specifically, when the lost‐revenue effect dominates the lost‐goodwill effect, these two strategies are complements; otherwise, they are substitutes. Furthermore, we examine the impact of market size, price sensitivity, supplier reliability, and failure rebate on the interplay between these two strategies, and discuss the implications of our results. Finally, we extend our analysis to the case of two unreliable suppliers and show that the insights regarding the interplay between diversification and pricing continue to hold.     

Why is diversification an attractive farm adjustment strategy? Insights from Texas farmers and ranchers

State agencies have been encouraging the development of different enterprises to diversify farm incomes in an effort to retain farmers in business, attract new entrants to agriculture and promote regional development. Entrepreneurship and farming are known to be driven by a complex set of goals including those which are economic and intrinsic in nature. However, little information is available regarding the set of goals that drive agriculture entrepreneurship, preventing state agencies to adequately target potential diversifiers. This paper provides a better understanding of the range of goals, both financial and nonfinancial, that are important in farmers' decisions to diversify their operations. The generation of additional income, the continuance of farming and ranching, and the enhancement of quality of life are among the most important diversification goals in Texas. A principal component factor analysis performed on the importance ratings of diversification goals resulted in six dimensions: (F1) Reduce Uncertainty and Risk; (F2) Grow and Service Markets; (F3) Enhanced Financial Condition; (F4) Individual Aspirations and Pursuits; (F5) Revenues Enhancement; and (F6) Family Connections. The study also examined the relationship between various entrepreneur and farm characteristics and the goal pursuit dimensions. Operator's age, number of generations the farm had been in the family, household income, number of farm employees, and distance to an urbanized area influence types of goals pursued through diversification.
