外生冲击与房地产真实价格波动--对1998~2003年中国31省(市、区)的实证研究 总被引:1,自引:0,他引:1
文章首先根据经济学模型界定了两个重要指标:自相关系数与收敛系数.认为不同的外生冲击对这两个系数有不同的影响,而它们决定了房地产真实价格波动形态的差异.在此基础上,文章利用1998~2003年中国31个省(市、区)的面板数据对中国房地产市场进行了实证研究,其结论是,在真实人均可支配收入和真实建筑成本较高、真实税后住宅抵押贷款利率较低的地区有较大的自相关系数和较小的收敛系数,从而房地产真实价格具有更大的波动性.为使房地产真实价格在均衡价格附近平稳运行,降低开发成本和提高消费者购买成本能收到较好的效果. 相似文献

Summary. We present a new class of rules named augmented serial rules for the provision of an excludable public good. First, we characterize this class by the four axioms of strategy-proofness, envy-freeness, access independence, and nonbossiness. Second, we identify two important subclasses by imposing an additional axiom: (i) anonymous augmented serial rules by anonymity, and (ii) Moulins serial rule by individual rationality.Received: 31 December 2002, Revised: 9 June 2004, JEL Classification Numbers:

We study the problem of assigning objects to a group of agents. We focus on probabilistic methods that take agents’ ordinal preferences over the objects. Importantly, we allow for indifferences among objects. Katta and Sethuraman (2006) propose the extended serial correspondence to solve this problem. Our main result is a characterization of the extended serial correspondence in welfare terms by means of stochastic dominance efficiency, stochastic dominance no-envy and “limited invariance,” a requirement we adapt from Heo (2014a). We also prove that an assignment matrix is selected by the extended serial correspondence if and only if it satisfies “non-wastefulness” and “ordinal fairness,” which we adapt from Kesten et al. (2011). 相似文献

We examine the quantile serial dependence in crude oil prices based on the Linton and Whang’s quantile-based portmanteau test which we improved by means of quantile wild bootstrapping (QWB). Through Monte Carlo simulation, we find that the quantile wild bootstrap-based portmanteau test performs better than the bound testing procedure suggested by Linton and Whang. We apply the improved test to examine the efficiency of two crude oil markets – WTI and Brent. We also examine if the dependence is stable via rolling sample tests. Our results show that both WTI and Brent are serially dependent in all, except the median quantiles. These findings suggest that it may be misleading to examine the efficiency of crude oil markets in terms of mean (or median) returns only. These crude oil markets are relatively more serially dependent in non-median ranges. 相似文献

Abstract The effects of fifteen barriers to participation were examined among people who expressed a desire for but were unable to participate in a new recreational activity. Work commitments, overcrowding of facilities, and lack of partners were the three main barriers. The effects of barriers were not perceived uniformly across the sample but varied between subgroups defined according to socioeconomic variables: the people most likely to be affected by barriers to participation included the poor, the elderly, and single parents. The extent to which recreation practitioners can and should respond to these kinds of research findings is discussed, and several ways in which the effects of barriers to participation might be modified or alleviated are evaluated. 相似文献

Individual users demand different quantities of a homogeneous good produced under variable returns. We describe the family of costsharing methods that allocate costs in proportion to demands when returns are constant, and commute with the additivity and composition of cost functions. Two simple such methods are average cost pricing and incremental costsharing. All other methods in the family combine elements of the average cost and incremental ones. Serial costsharing stands out prominently in the family, whereas the Shapley–Shubik method, and all values from the associated stand alone cooperative game, are excluded.Journal of Economic LiteratureClassification Numbers: D63, C71. 相似文献
