Market potential, increasing returns and geographic concentration   总被引:17,自引:0,他引:17  
In this paper, I examine the spatial correlation between wages and consumer purchasing power across U.S. counties to see whether regional demand linkages contribute to spatial agglomeration. First, I estimate a simple market-potential function, in which wages are associated with proximity to consumer markets. Second, I estimate an augmented market-potential function derived from the Krugman model of economic geography, parameter estimates for which reflect the importance of scale economies and transport costs. The estimation results suggest that demand linkages between regions are strong and growing over time, but quite limited in geographic scope.  相似文献

Boom‐bust cycles in real estate markets have been major factors in systemic financial crises and therefore need to be at the forefront of macroprudential policy. The geographically differentiated nature of real estate market fluctuations implies that these policies need to be granular across regions and countries. Before the financial crisis that started in 2007 property markets were overvalued in a range of European countries, but much like in other constituencies active policies addressing this were an exception. An increasing number of studies suggest that borrower‐based regulatory policies, such as reductions in loan‐to‐value or debt‐to‐income limits, can be effective in leaning against real estate booms. But many of the new macroprudential policy authorities in Europe do not have clear powers to determine them. Moreover, the cross‐border spillovers they may give rise to suggest the establishment of a well‐defined macroprudential coordination mechanism for the single European market.  相似文献

The Campbell–Shiller present value formula implies a factor structure for the price–rent ratio of housing market. Using a dynamic factor model, we decompose the price–rent ratios of 23 major housing markets into a national factor and independent local factors, and we link these factors to the economic fundamentals of the housing markets. We find that a large fraction of housing market volatility is local and that the national factor has become more important than local factors in driving housing market volatility since 1999, consistent with the findings in Del Negro and Otrok (2007). The local volatilities mostly are due to time variations of idiosyncratic housing market risk premia, not local growth. At the aggregate level, the growth and interest rate factors jointly account for less than half of the total variation in the price–rent ratio. The rest is due to the aggregate housing market risk premium and a pricing error. We find evidence that the pricing error is related to money illusion, especially at the onset of the recent housing market bubble. The rapid rise in housing prices prior to the 2008 financial crisis was accompanied by both a large increase in the pricing error and a large decrease in the housing market risk premium.  相似文献

为了研究沪港通对沪市股票市场有效性的影响,本文选取2000—2015年上证股指,运用 R/S 分析并结合 DFA 统计量得出:沪市股票市场存在明显的长期记忆性,但沪港通之后其长期和短期记忆性显著下降。基于 ARFIMA 模型的预测效果与长期记忆性特征之间得出对应关系:如果长期记忆性显著,则预测效果好;如果记忆性不明显,则预测效果差。本文对沪港通前后进行长度为10步的分数阶自回归模型预测,结果显示 ARFIMA 模型对沪指收益率整体的预测效果较好,但沪港通开通之后模型的预测效果却明显减弱。  相似文献

利用2009—2011年中国制造业上市公司的数据,采用面板数据回归方法探讨了金融集聚对企业R&D投资的影响。实证研究结果显示:地区金融集聚程度与企业的R&D投资强度显著正相关;两者的正相关关系会受到企业所有权性质和企业规模的影响:金融集聚和R&D投资之间显著的正相关关系仅存在于非国有控股企业样本组中;金融集聚对R&D投资的影响在小企业样本中更为明显。  相似文献

This article presents a proposal for a simultaneous competitiveness measurement model for the three geographical levels: country, states, and municipalities. For this, a multivariate factor analysis method is used to help identify five factors, seven sub-factors, and thirty variables, which will be used for the measurement and to present the results of an empirical study on eleven entities: the country, the State of Sonora, and nine municipalities, which represent 80% of the population and 80% of their TGP. The results indicate that, in 2010, the municipality of Hermosillo was the most competitive.  相似文献

The authors investigate R 2 and its relationship with dividend payouts in the Korean stock market. R 2 is derived from the market model regression. Their results are consistent with the previous literature on corporate governance and dividend payouts: they find that R 2 is higher for business group (chaebol) firms and that there is a negative relationship between R 2 and dividend payout. However, the relationship is not stronger for the business group firms than for the non-business group firms. The findings elucidate the relationship between R 2 and dividend payout policy in the United States.  相似文献

We use unique information on migration behaviour and reasons for migration to study the impact of tied migration on labour market outcomes among husbands and wives. Fewer than 2% of couples migrate for job‐related reasons and the majority of these move for reasons associated with the husband's job. Estimates from dynamic random‐effects models indicate that husbands and wives in couples that migrated for job‐related reasons suffer lower job retention rates than non‐migrants. Tied migration reduces the probability of subsequent employment for both husbands and wives and in particular has a large negative impact on job retention rates among wives.  相似文献

Agriculture is one of the most hazardous productive sectors around the world. Most previous studies have focused on health issues of farmers in developing countries, while little attention has been paid to farmers' health problems in developed countries. The present study assesses the effect of farmers' health conditions on agricultural productivity in Norway. Employing stochastic frontier regression techniques, we conclude that differences in farmers' health help to explain the variance in agricultural production efficiency.  相似文献

We visit the role of privatization in the location decision of firms in an industry where no firm can produce all varieties demanded. We demonstrate that the Nash equilibrium locations are socially optimal, in the presence of a publicly owned firm, notwithstanding the degree of privatization.  相似文献
