住宅是一种异质性商品,它的构成使用价值的各个特征之间有明显的差异,因此特征价格定价模型广泛用于住宅的价值评估。但是由于住宅数据中常常表现出空间问题,使得传统的特征价格模型不再适用,空间效应在不动产领域的存在引起了学者们的广泛关注。对空间分析在住宅价值评估中的应用研究进行了回顾和阐述,首先分析空间效应的来源和影响,讨论了在传统模型中纳入空间效应的重要性,接着阐述如何对这些空间效应进行有效建模和检验,并分析了进一步研究的方向。 相似文献

制造企业的内部资源有效配置是关系到转型升级成效的内在问题,但资源配置的组态如何影响转型升级成效尚没有得到充分研究。文章将企业的资源要素分为研发投入、人才水平、发展潜力以及客户集中度四个方面,将企业规模设为调节变量,运用模糊集定性比较分析方法,对31家制造企业进行实证研究,得到资源配置的四种有效组态形式为:高抗风险型、高创新投入型、高市场地位型以及紧密客户关系型。研究结论证实了转型升级资源配置组态效应的客观存在,既丰富了企业转型升级理论及方法,也为企业转型升级的路径选择及有效性分析提供了的启示和参考。 相似文献

This paper analyzes Milton Friedman's (1968a) article “The Role of Monetary Policy,” via a discussion of seven fallacies concerning the article. These fallacies are as follows: (i) “The Role of Monetary Policy” was Friedman's first public statement of the natural rate hypothesis. (ii) The Friedman–Phelps Phillips curve was already present in Samuelson and Solow's (1960) analysis. (iii) Friedman's specification of the Phillips curve was based on perfect competition and no nominal rigidities. (iv) Friedman's (1968a) account of monetary policy in the Great Depression contradicted the Monetary History’s version. (v) Friedman (1968a) stated that a monetary expansion will keep the unemployment rate and the real interest rate below their natural rates for two decades. (vi) The zero lower bound on nominal interest rates invalidates the natural rate hypothesis. (vii) Friedman's (1968a) treatment of an interest-rate peg was refuted by the rational expectations revolution. The discussion lays out the reasons why each of these seven items is a fallacy and infers key aspects of the framework underlying Friedman's (1968a) analysis. 相似文献

ABSTRACT Land market regulations are often justified by the assumption that activities of foreign and non-agricultural investors drive up prices in domestic land markets. However, empirical knowledge about the dynamics of agricultural land prices across borders is sparse. Using the German reunification as a natural experiment, we study the effect of the former inner German border on the dynamics of agricultural land prices in East and West Germany. We apply a land price diffusion model with an error correction specification to analyse spatial agricultural land markets. A novel feature of our model is its ability to distinguish price diffusion within states and across state borders. We provide evidence for a persistent border effect given that the fraction of spatially integrated counties is larger within states than across the former border. Moreover, we observe non-significant error correction terms for many counties along the former border. From a policy perspective, it is striking to realize that even 25 years after German reunification, pronounced land price differences persist. It is quite likely that price diffusion through existing borders within the EU would take even more time given language barriers, different institutional frameworks, and information asymmetries between domestic and foreign market participants. 相似文献

本文首先基于住房财富效应,构建了房价变动对居民消费的跨空间影响的分析框架。该框架阐释了住房财富效应的区域差异:不同地区间房价的空间传导、居民的异地消费以及消费的示范效应,使得本地房价变动可能引起周边地区居民消费的连锁反应。其后,本文利用中国278个地级市2000—2018年数据,通过空间面板杜宾模型,实证考察了不同地区住房财富效应的差异,以及房价变动对居民消费的跨空间影响。结果显示:(1)虽然中国整体上存在住房财富效应,但西部城市财富效应并不显著,并且核心城市还存在负财富效应。(2)不同城市间房价对消费存在跨区影响。东部城市和核心城市对周边城市消费的正向影响很显著,而边缘城市则对周边城市消费有显著的负向影响。(3)不同城市间的消费也具有空间上的示范效应。最后,本文从房价和居民消费空间联动的视角,为政府扩大内需、调控房地产市场提供了相关政策建议。 相似文献

We exploit a regression discontinuity design to provide causal evidence of the relative age effect (RAE) on a long-run adult age outcome: Political selection. We find strong evidence of the RAE in politics in Finland. However, the effect is heterogeneous: We find that male candidates born early in the calendar year have a significantly higher probability of getting elected to the parliament but no similar RAE applies to female candidates nor to municipal elections. Moreover, this effect only takes place in the most competitive parliamentary districts and is present only for some parties. We also find that in all the groups where the RAE does not exist, early-born candidates are under-represented suggesting attrition of talent in the candidate placement. Overall, our results show that seemingly artificial cutoffs imposed by the government have persistent consequences even on the selection to the highest positions of power within a society. 相似文献

We analyze whether product market advertising has a spillover effect on stock price synchronicity by transmitting firm-specific information to the capital market and attracting more investor attention. Using a sample of Chinese listed firms from 2009 to 2017, we find that firms with greater advertising expenditures have lower stock price synchronicity. The results are robust after we address endogeneity concerns. In accord with our hypothesis that product market advertising increases the amount of firm-level information capitalized into stock prices through the information channel, we find that the impact of advertising on synchronicity is more pronounced for firms with a higher degree of information asymmetry and firms in the consumer-product industry. Further tests show that product market advertising enhances the ability of current period returns to reflect future earnings, and thus rules out that the negative relationship between advertising and synchronicity is driven by noise trading. Our results imply that product market advertising plays an informative role and improves information efficiency in a capital market. 相似文献

Benchmark models that exogenously specify equity dynamics cannot explain the large spread in prices between put options written on individual banks and options written on the bank index during the financial crisis. However, theory requires that asset dynamics be specified exogenously and that endogenously determined equity dynamics exhibit a “leverage effect” that increases put prices by fattening the left tail of the distribution. The leverage effect is larger for puts on individual stocks than for puts on the index, thus increasing the basket-index spread. Time-series and cross-sectional variation in the leverage effect explains option prices well. 相似文献

通过空间计量模型考察生产性服务业发展模式与制造业集聚的空间溢出效应后发现:生产性服务业专业化水平及多样化水平与制造业集聚呈倒U型关系,同时城市化水平会对服务业发展模式与制造业集聚关系产生影响。分区域模型研究发现,生产性服务业对制造业全要素生产率影响因区域经济发展水平、产业层次、要素禀赋等因素有所差异,东部地区制造业全要素生产率与生产性服务业呈线性关系,适合选择多样化发展模式;中部地区呈倒U型关系,现阶段中部地区生产性服务业更适合选择多样化发展模式;西部地区生产性服务业发展水平与制造业全要素生产率呈正U型关系,生产性服务业专业化和多样化发展都将促进制造业全要素生产率提升。 相似文献
