Purpose

The purpose of this study is to analyse the trends regarding housing segregation over the past 10–20 years and determine whether housing segregation has a spillover effect on neighbouring housing areas. Namely, the authors set out to determine whether proximity to a specific type of segregated housing market has a negative impact on nearby housing markets while proximity to another type of segregated market has a positive impact.

Design/methodology/approach

For the purposes of this paper, the authors must combine information on segregation within a city with information on property values in the city. The authors have, therefore, used data on the income of the population and data on housing values taken from housing transactions. The case study used is the city of Stockholm, the capital of Sweden. The empirical analysis will be the estimation of the traditional hedonic pricing model. It will be estimated for the condominium market.

Findings

The results indicate that segregation, when measured as income sorting, has increased over time in some of the housing markets. Its effects on housing values in neighbouring housing areas are significant and statistically significant.

Research limitations/implications

A better understanding of the different potential spillover effects on housing prices in relation to the spatial distribution of various income groups would be beneficial in determining appropriate property assessment levels. In other words, awareness of this spillover effect could improve existing property assessment methods and provide local governments with extra information to make an informed decision on policies and services needed in different neighbourhoods.

Practical implications

On housing prices emanating from proximity to segregated areas with high income differs from segregated areas with low income, policies that address socio-economic costs and benefits, as well as property assessment levels, should reflect this pronounced difference. On the property level, positive spillover on housing prices near high-income segregated areas will cause an increase in the number of higher income groups and exacerbate segregation based on income. Contrarily, negative spillover on housing prices near low-income areas might discourage high-income households from moving to a location near low-income segregated areas. Local government should be aware of these spillover effects on housing prices to ensure that policies intended to reduce socioeconomic segregation, such as residential and income segregation, produce desirable results.

Social implications

Furthermore, a good estimation of these spillover effects on housing prices would allow local governments to carry out a cost–benefit analysis for policies intended to combat segregation and invest in deprived communities.

Originality/value

The main contribution of this paper is to go beyond the traditional studies of segregation that mainly emphasise residential segregation based on income levels, i.e. low-income or high-income households. The authors have analysed the spillover effect of proximity to hot spots (high income) and cold spots (low income) on the housing values of nearby condominiums or single-family homes within segregated areas in Stockholm Municipality in 2013.

隔离的住房市场对附近住宅区的房价有溢出效应吗？

目的

本研究的目的是分析过去 10-20 年住房隔离的趋势，并确定住房隔离是否对邻近的住房区域产生溢出效应。也就是说，作者着手确定靠近特定类型的隔离住房市场是否会对附近的住房市场产生负面影响，而靠近另一种类型的隔离市场是否会产生积极影响。

设计/方法/方法

就本文而言，作者必须将有关城市内部隔离的信息与有关该城市财产价值的信息结合起来。因此，作者使用了人口收入数据和从住房交易中获取的住房价值数据。使用的案例研究是瑞典首都斯德哥尔摩市。实证分析将是对传统享乐定价模型的估计。预计将用于公寓市场。

发现

结果表明，以收入分类衡量的隔离在某些住房市场中随着时间的推移而增加。它对邻近住宅区的住宅价值的影响是显着的，并且具有统计学意义。

研究限制/影响

更好地了解与不同收入群体的空间分布相关的对房价的不同潜在溢出效应将有助于确定适当的财产评估水平。换句话说，对这种溢出效应的认识可以改进现有的财产评估方法，并为地方政府提供额外的信息，以便就不同社区所需的政策和服务做出明智的决定。

实际影响

关于靠近高收入隔离区与低收入隔离区的房价不同，解决社会经济成本和收益以及财产评估水平的政策应反映这种显着差异。在房地产层面，高收入隔离区附近房价的正向溢出将导致高收入群体数量增加，加剧基于收入的隔离。相反，低收入地区附近房价的负溢出可能会阻止高收入家庭搬到靠近低收入隔离区的地方。地方政府应该意识到这些对房价的溢出效应，以确保旨在减少社会经济隔离的政策，如住宅和收入隔离，产生理想的结果。

社会影响

此外，对这些对房价的溢出效应的良好估计将使地方政府能够对旨在打击隔离和投资于贫困社区的政策进行成本效益分析。

原创性/价值

本文的主要贡献是超越了传统的隔离研究，这些研究主要强调基于收入水平的居住隔离，即低收入或高收入家庭。作者分析了 2013 年斯德哥尔摩市隔离区内靠近热点（高收入）和冷点（低收入）对附近公寓或单户住宅的住房价值的溢出效应。
