In micro-level data concerning the housing market, the apartment quality may be signaled via textual statements or the attached descriptions/photos. It may be done using hard information related to the easier-to-measure structural characteristics or soft information related to the apartment condition and design - soft quality. This paper checks whether the choice of the approach to handling the issue of soft quality of apartments influences the properties of hedonic models and the course of hedonic rent indices. The study shows that hedonic models that account for soft quality have better statistical properties than those without soft-quality-related variables. Among them, the models that include the information on quality extracted from descriptions of apartments prove to be the best. Still, considerable differences in the indicated course of hedonic rent indices have not been detected. However, the paper concludes that utilizing information on apartments’ soft quality may be crucial to understanding the market adjustment process to economic shocks. It has been proven that the price reaction of the Poznań (Poland) rental market to the COVID-19 pandemic and the Russian aggression on Ukraine has been diversified in the quality-related market segments.
在有关住房市场的微观数据中,公寓质量可通过文字说明或所附说明/照片来表示。可以使用与较易测量的结构特征相关的硬信息,也可以使用与公寓条件和设计相关的软信息--软质量。本文检验了处理公寓软质量问题的方法选择是否会影响保值模型的属性和保值租金指数的走势。研究表明,考虑了软质量问题的保值模型比没有软质量相关变量的模型具有更好的统计特性。其中,包含从公寓描述中提取的质量信息的模型被证明是最好的。尽管如此,在享乐主义租金指数的指示过程中并未发现显著差异。不过,本文的结论是,利用公寓的软质量信息可能对理解市场对经济冲击的调整过程至关重要。事实证明,波兹南(波兰)租赁市场对 COVID-19 大流行病和俄罗斯入侵乌克兰的价格反应在与质量相关的细分市场上是多样化的。

The research objective of the article was to assess the potential of residential property in Poland as an inflation hedge investment. The study was conducted using innovative measures of the level of inflation hedging. The study was made for Poland’s six largest local residential markets, for two types of investments, for different investment horizons (from 6 to 15 years). The research period adopted was: 3Q2006-4Q2022. In all cities, investments providing only capital gains allowed an attractive inflation hedging level to be achieved. Investments that additionally included rental offered a high inflation hedging level. The variation in the six cities studied in terms of inflation hedging through housing investment was found to be very low. The question of how extending the investment horizon affected the inflation hedging ability was not firmly answered. Frequently, the extension of the investment horizon has been accompanied by an increase in the level of hedging.
文章的研究目标是评估波兰住宅物业作为通货膨胀对冲投资的潜力。研究采用了创新的通胀对冲水平测量方法。研究针对波兰六个最大的本地住宅市场,针对两种投资类型,针对不同的投资期限(6 至 15 年)。研究周期为2006 年第三季度至 2022 年第四季度。在所有城市中,仅提供资本收益的投资可达到有吸引力的通货膨胀对冲水平。另外还包括租金的投资提供了较高的通胀对冲水平。研究发现,六个城市在通过住房投资对冲通胀方面的差异非常小。关于延长投资期限如何影响通胀对冲能力的问题,没有得到确切的答案。通常情况下,投资期限的延长伴随着对冲水平的提高。

Endowment Effect, Information Asymmetry, and Real Estate Market Decisions: Willingness to Pay and Willingness to Accept Disparities 禀赋效应、信息不对称与房地产市场决策:支付意愿和接受差异的意愿

The endowment effect has gained dominance over the decades due to its ability to explain behavioral instincts portrayed by individuals when making decisions and its inconsistency with standard economic theories. It has been extensively applied in different fields of study, however its applicability to the housing market has been limited since its establishment. The study seeks to investigate whether the endowment effect exists in the housing market and whether the disclosure of information, increased affordability and agent evaluation significantly reduce the endowment effect. Using data obtained from a survey conducted between January and August 2022 in the Eastern Cape Province of South Africa, the study found that the disclosure of information eliminates the gap between buyers’ valuations and market values, while the gap between sellers’ valuations and market prices is reduced but not eliminated by information disclosure. The study has further concluded that increased affordability and agent evaluations significantly reduce the endowment effect in the housing market. Therefore, the study recommends that private and public entities should establish laws and regulations which promote the disclosure of information to reduce the gap between the willingness to pay (WTP) and the willingness to accept (WTA) that exists in the market.
几十年来,禀赋效应因其能够解释个人在决策时的行为本能以及与标准经济理论的不一致性而占据主导地位。它已被广泛应用于不同的研究领域,但自其问世以来,对住房市场的适用性一直受到限制。本研究试图探讨住房市场中是否存在禀赋效应,以及信息披露、可负担性提高和代理评估是否会显著降低禀赋效应。利用 2022 年 1 月至 8 月期间在南非东开普省进行的一项调查所获得的数据,研究发现,信息披露消除了买方估值与市场价值之间的差距,而卖方估值与市场价格之间的差距有所缩小,但并未因信息披露而消除。研究进一步得出结论,提高可负担性和代理评价会显著降低住房市场的禀赋效应。因此,研究建议私营和公共实体应制定促进信息披露的法律法规,以缩小市场上存在的支付意愿(WTP)和接受意愿(WTA)之间的差距。

Our research into the fast-growing segment of the rental market fits perfectly with the current wave of excitement. In this research, we attempt to answer a fundamental question: how large is the rental segment in Poland? To our surprise, the answer to this key question remains wrapped in mystery, with an absence of continuous studies disclosing its true size. Undaunted, in this paper we took up the challenge to develop a method that would give us a clear answer. Using Eurostat statistics, we develop a methodological framework for estimating the size of the rental segment. We acknowledge that Eurostat data possesses certain limitations, yet serves as a valuable resource for fulfilling our goal under the proposed methodology. In our approach, we determine the size of Polish rental segment between 2007 and 2021. To validate our findings, we dived into the complex relationship between the size of the rental segment and households. Applying linear regression, we sought to unravel the main determinants influencing not only the overall housing market but also the dimensions of the puzzling rental segment. The proposed method proves to be successful and answers the research question. However, it is important to emphasize that the presented results are estimates that give an impression of the elusive size of the rental housing segment and not exact measurements. Moreover, the flexibility of the proposed methodology is promising and allows similar studies to be conducted in different geographical contexts.
我们对快速增长的租赁市场的研究与当前的兴奋浪潮完全吻合。在这项研究中,我们试图回答一个基本问题:波兰的租赁市场到底有多大?出乎我们意料的是,这个关键问题的答案仍然是个谜,缺乏披露其真实规模的连续性研究。在本文中,我们不畏艰难,接受挑战,开发出一种能给出明确答案的方法。我们利用欧盟统计局的统计数据,建立了一个估算租赁市场规模的方法框架。我们承认欧盟统计局的数据具有一定的局限性,但在我们提出的方法中,这些数据是实现我们目标的宝贵资源。在我们的方法中,我们确定了 2007 年至 2021 年波兰租赁市场的规模。为了验证我们的研究结果,我们深入研究了租赁市场规模与家庭之间的复杂关系。通过线性回归,我们试图揭示影响整体住房市场以及令人费解的租赁市场规模的主要决定因素。事实证明,所提出的方法是成功的,回答了研究问题。然而,必须强调的是,所提出的结果只是估计值,给人的印象是租房群体的规模难以捉摸,而不是精确的测量值。此外,拟议方法的灵活性也很有前景,可以在不同的地理环境中开展类似的研究。

Every road investment has both positive and negative consequences in spatial, economic, environmental, and social terms. The objective of the article is the social assessment of the effect of construction of the Southern Warsaw Ring Road (WRR) on: (i) the quality of life of the local community, and (ii) the residential real estate market. The analyses employed the method of quantitative analysis with the application of the survey technique. The questionnaire was made publicly available to residents of the Wilanów district in Warsaw. Results obtained in the scope of the study render decision making models of respondents depending on the distance of the place of residence from the WRR. The results reveal that responses given by the group of respondents living nearer the ring road are the most variable, particularly in the context of assessing the effect of the investment on the quality of life, including nuisance related to the express road and plans to change the place of residence. The same group of respondents provided the highest share of responses supporting the claim that housing prices increased due to the construction of the ring road.
每项道路投资都会在空间、经济、环境和社会方面产生积极和消极的影响。本文旨在对华沙南环路(WRR)建设对以下方面的影响进行社会评估:(i) 当地社区的生活质量,以及 (ii) 住宅房地产市场。分析采用了定量分析方法和调查技术。问卷向华沙 Wilanów 区的居民公开发放。在研究范围内获得的结果呈现了受访者根据居住地与 WRR 的距离而做出决策的模式。结果显示,居住在环城路附近的受访者群体的回答最具可变性,尤其是在评估投资对生活质量的影响方面,包括与快速路相关的滋扰和改变居住地的计划。同一组受访者中支持房价因修建环城路而上涨这一说法的比例最高。

The scale of environmental pressure caused by the construction sector has prompted a search for new technical solutions to minimize the negative impact of this part of the national economy on the environment. The drive to evaluate the adopted solutions has led to the creation of building assessment systems - environmental certificates. The aim of the article is both to introduce the certification processes used in the Polish residential property market and to indicate the locations of residential investments that have obtained the certificates in question. The paper takes a closer look at environmental certification using multi-criteria building assessment systems, i.e. BREEAM, LEED and HQE. The time scope of the presented research covered the years 2016 to the first quarter of 2022. The research carried out allowed an upward trend to be observed in the number of environmental certificates awarded, indicating the use of green building principles for residential properties. It is certain that there has been a development of this type of investment in Poland in the recent years. An analysis of the spatial distribution of the surveyed investments shows that location clusters have formed - green (low-emission) residential investments are distributed in the largest cities in Poland, which are characterized by a strictly defined consumer profile.
建筑业对环境造成的巨大压力促使人们寻找新的技术解决方案,以最大限度地减少国民经济的这一部分对环境的负面影响。对所采用的解决方案进行评估的动力导致了建筑评估系统--环境证书--的诞生。本文的目的是介绍波兰住宅房地产市场所使用的认证程序,并指出获得相关证书的住宅投资地点。本文通过多标准建筑评估系统(即英国建筑性能评估体系、美国能源与环境设计先锋奖和 HQE)对环境认证进行了深入研究。本文研究的时间范围涵盖 2016 年至 2022 年第一季度。通过研究可以发现,颁发的环保证书数量呈上升趋势,这表明住宅物业采用了绿色建筑原则。可以肯定的是,近年来波兰的此类投资有所发展。对所调查的投资空间分布的分析表明,已经形成了地点集群--绿色(低排放)住宅投资分布在波兰最大的城市,这些城市的特点是有严格定义的消费者特征。

Low Interest Rates and Uncreative Destruction in the Office Market 低利率与写字楼市场的非创造性破坏
Pub Date : 2024-02-20 DOI: 10.2478/remav-2024-0018
Krzysztof Olszewski, Dariusz Trojanowski, J. Łaszek
Low interest rates were introduced in the global economy to support the weak economic growth that followed the global financial crisis. In the real estate sector, low interest rates usually lead to a boom in investment and prices. This boom, however, is not spread throughout the economy, but rather concentrated in major cities. We demonstrate this phenomenon on the example of the office market in Warsaw (Poland). While it would be beneficial for the Polish economy to develop office space in smaller cities that have an insufficient supply of modern office space, investors have focused mainly on the capital. This has not only led to an increase in the cost of building land and construction, but has also pushed some relatively new existing office buildings off the market. We call such behaviour uncreative destruction and explain why it was possible.
全球金融危机爆发后,经济增长乏力,为支持经济增长,全球经济开始实行低利率。在房地产领域,低利率通常会导致投资和价格的繁荣。然而,这种繁荣并没有遍及整个经济,而是集中在大城市。我们以波兰华沙的写字楼市场为例说明这一现象。虽然在现代办公空间供应不足的小城市发展办公空间对波兰经济有利,但投资者却主要集中在首都。这不仅导致了建筑用地和建筑成本的增加,也将一些相对较新的现有办公楼挤出了市场。我们将这种行为称为 "非创造性破坏",并解释了其产生的原因。

In recent years, machine learning algorithms have been used in the mass appraisal of real estate. In this study, 5 machine learning algorithms are used for residential type real estate. Machine learning algorithms used for mass appraisal in this study are Artificial Neural Networks (ANN), Random Forest (RO), Multiple Regression Analysis (MRA), K-Nearest Neighborhood (k-nn), Support Vector Regression (SVR). To test the study, real estate data collected from the central districts of Ankara, were used. The main purpose of this study is to find out which machine learning algorithm gives the best results for the mass appraisal of real estates and to reveal the most important variables that affect the prices of real estate. According to the results obtained for the city of Ankara, it was observed that the best algorithm for mass appraisal is RF in residential-type real estates, followed by the ANN, k-nn, and linear regression algorithms, respectively. According to the results obtained from the residential real estate, it was concluded that heating and distances to places of importance had the greatest effect on the value.

The study addresses the problem of diverse housing conditions experienced by seniors in Poland and equipping their apartments with installations improving the quality of life for people with reduced mobility, taking into account various forms of residential premises ownership: a condominium, a cooperative apartment and a council flat. The study aimed at providing answers to a number of questions, including: what is the readiness to change an apartment into a council flat adapted to the needs of people with mobility limitations, taking into account the current ownership status of the apartment (condominium, cooperative member’s ownership right to residential premises, the right to rent a flat from the council-owned housing resources). The research was conducted in the cities of Wrocław and Jelenia Góra, located in Poland in the Lower Silesia Voivodship. A total of 208 people aged 50 and over were covered by the study. The authors found correlations between access to utilities and facilities in an apartment and the form of ownership of the dwelling. Among other things, the survey found that a toilet in the stairwell and the lack of central heating are much more common in communal apartments than in cooperative apartments and condominiums. Residents also pointed to the need to adapt bathrooms that are located in apartments. Tenants of public housing were also more likely to express a desire to adapt their apartments to the needs of people with limited mobility.
这项研究针对的是波兰老年人所经历的不同住房条件问题,以及为他们的公寓配备改善行动不便者生活质量的设施问题,同时考虑到各种形式的住宅所有权:公寓、合作公寓和议会公寓。这项研究旨在回答一系列问题,其中包括:考虑到公寓目前的所有权状况(公寓、合作社成员对住宅的所有权、从议会拥有的住房资源中租房的权利),将公寓改建为适应行动不便者需求的议会公寓的准备程度如何。研究在波兰下西里西亚省的弗罗茨瓦夫市和耶莱尼亚戈拉市进行。研究共涉及 208 名 50 岁及以上的人。作者发现,公寓内公用设施的使用情况与住宅的所有权形式之间存在关联。除其他外,调查还发现,与合作公寓和共管公寓相比,公共公寓中楼梯间的厕所和缺乏中央供暖系统的情况要普遍得多。居民们还指出,需要对位于公寓内的浴室进行改造。公共住房的租户也更有可能表示希望对公寓进行改造,以满足行动不便者的需求。

Transportation Management in Urban Functional Areas 城市功能区的交通管理
Pub Date : 2024-02-20 DOI: 10.2478/remav-2024-0021

Urban and suburban transport within Functional Urban Areas (FUAs) is now considered an integrated system. In these regions, many residents commute from the suburbs to the city daily for work, education, and social purposes. Transport planning must consider these dynamics to ensure consistent and convenient connections between the city and its suburbs. This article stresses the need for a standardized tool to collect data on transport management models in FUAs across 38 OECD-affiliated countries. The proposed tool, a survey questionnaire, aims to gather information on how transport management models are organized and operate in these regions. The article discusses research conducted in the Olsztyn FUA, revealing significant variations in transport management methods among municipalities. The questionnaire is categorized into four themes: public transport, transport infrastructure, FUA transport strategy and innovation, and risks and monitoring, offering a comprehensive view of the transport management model. The study also highlights varying development priorities among FUA municipalities; some focus on public transport, while others invest in road infrastructure. This study underscores the importance of a cohesive approach to transport management in FUAs, considering their diverse needs and requirements.
城市功能区(FUA)内的城市和郊区交通现已被视为一个综合系统。在这些地区,许多居民每天都要从郊区前往市区工作、上学和社交。交通规划必须考虑这些动态因素,以确保城市与郊区之间连贯、便捷的连接。本文强调,需要一种标准化工具来收集 38 个经合组织成员国的友好城市交通管理模式数据。拟议的工具是一份调查问卷,旨在收集有关这些地区如何组织和运作交通管理模式的信息。文章讨论了在奥尔什丁联邦行政区开展的研究,揭示了各市在交通管理方法上的显著差异。调查问卷分为四个主题:公共交通、交通基础设施、FUA 交通战略与创新以及风险与监控,从而对交通管理模式提供了一个全面的视角。本研究还强调了 FUA 各市不同的发展重点;一些城市侧重于公共交通,而另一些则投资于道路基础设施。考虑到各联邦直辖区的不同需求和要求,本研究强调了在联邦直辖区采取协调一致的交通管理方法的重要性。
