This paper measures how much households dislike density in their immediate surroundings. Using transaction and administrative data in Singapore, and exploiting the introduction of a regulation that restricted the number of housing units for certain land lots, we find that households do indeed discount density: a 10% increase in within-development density decreases price per square meter by up to 4%. Further, we find that the mean price per square meter of the average development increased by 1 to 3% after the regulation was introduced, while the amount of built-up space remained constant. The increase in total revenue suggests that developers may underestimate the externality caused by density. Our results are particularly relevant during the lockdowns and social distancing of the coronavirus pandemic.
这篇论文测量了有多少家庭不喜欢他们周围的密度。利用新加坡的交易和行政数据,并利用限制特定地块住房单位数量的规定,我们发现家庭确实会对密度进行折扣:开发内密度增加10%,每平方米价格最多会下降4%。此外,我们发现,在监管出台后,平均开发项目的每平方米平均价格上涨了1%至3%,而建筑面积保持不变。总收入的增长表明,开发商可能低估了密度带来的外部性。我们的研究结果在冠状病毒大流行的封锁和保持社交距离期间尤为重要。

Real Options Problem with Non-Smooth Obstacle 非平滑障碍的实物期权问题
Pub Date : 2020-12-17 DOI: 10.2139/ssrn.3751068

We consider a real options problem, which is posed as a stochastic optimal control problem. The investment strategy, which plays the role of control, involves a one-time option to expand (invest) and a one-time option to abandon (terminate) the project. The timing and amount of the investment and the termination time are parameters to be optimized in order to maximize the expected value of the profit. This stochastic optimization problem amounts to solving a deterministic variational inequality in dimension one, with the associated obstacle problem. Because we consider both cessation and expansion options and fixed and variable costs of expansion, the obstacle is non-smooth. Due to the lack of smoothness, we use the concept of a weak solution. However, such solutions may not lead to a straightforward investment strategy. Therefore, we further consider strong ($C^1$) solutions based on thresholds. We propose sufficient conditions for the existence of such solutions to the variational inequality with a non-smooth obstacle in dimension one. When applied to the real options problem, these sufficient conditions yield a simple optimal investment strategy with the stopping times defined in terms of the thresholds.
考虑一个实物期权问题,该问题被视为随机最优控制问题。投资策略具有控制作用,包括扩大(投资)项目的一次性选择和放弃(终止)项目的一次性选择。为了实现利润期望值的最大化,投资的时机和金额以及终止时间都是需要优化的参数。这个随机优化问题相当于解决一个一维的确定性变分不等式,以及相关的障碍问题。因为我们同时考虑了停止和扩张的选择,以及扩张的固定和可变成本,所以障碍并不平坦。由于缺乏平滑性,我们使用弱解的概念。然而,这样的解决方案可能不会导致直接的投资策略。因此,我们进一步考虑基于阈值的强($C^1$)解。我们给出了一类一维非光滑障碍物变分不等式解存在的充分条件。当应用于实物期权问题时,这些充分条件产生了一个简单的最优投资策略,并根据阈值定义了停止时间。

This paper proposes the use of a semiparametric model based on a locally weighted approach that controls for dynamic agglomeration and diffusion effects in constructing localized housing price indices. Based on residential transaction records in Singapore, we create a three-dimensional interactive heat maps that allow for better measurement and visualization of spatial variations and heterogeneity in price appreciation. The heat map captures regional variations and temporal dispersions in price appreciation rates in the business cycle. Our methodology provides high-resolution information about price dynamics that could aid individual buyers, investors, and policy makers in making objective and informed decisions.

Climate Change Risk and the Cost of Mortgage Credit 气候变化风险和抵押贷款成本
Pub Date : 2020-11-26 DOI: 10.2139/ssrn.3738234

We show that lenders charge higher interest rates for mortgages on properties exposed to a greater risk of sea level rise (SLR). This SLR premium is not evident in short-term loans and is not related to borrowers’ short-term realized default or creditworthiness. Further, the SLR premium is smaller when the consequences of climate change are less salient and in areas with more climate change deniers. Overall, our results suggest that mortgage lenders view the risk of SLR as a long-term risk and that attention and beliefs are potential barriers through which SLR risk is priced in residential mortgage markets.
我们表明,贷款人对暴露在海平面上升(SLR)风险更大的房产的抵押贷款收取更高的利率。这种SLR溢价在短期贷款中并不明显,也与借款人的短期已实现违约或信誉无关。此外,当气候变化的后果不太突出以及在气候变化否认者较多的地区,SLR溢价较小。总体而言,我们的研究结果表明,抵押贷款机构将单反风险视为一种长期风险,并且关注和信念是住宅抵押贷款市场中单反风险定价的潜在障碍。

The Housing Crisis and the Constitution 住房危机和宪法
Pub Date : 2020-11-16 DOI: 10.2139/SSRN.3731506
H. Hogan, Finn Keyes
Ireland has been in the grip of a housing crisis for several years. Lately, there have been mounting calls for a referendum to introduce a right to housing in the Constitution. Regardless of the merits of this proposal, it stems, in part, from a perception that the Constitution in its current form inhibits the Oireachtas from taking radical steps to remedy the housing crisis. We argue instead that legal interpretations of constitutional case law have over-estimated the degree to which the courts will protect individual property rights at the expense of the common good. In Part I, we outline the case law relating to the protection of property rights in the Constitution, and identify a number of key principles. We conclude from an examination of Irish case law that the courts have, largely, deferred to the Oireachtas in restricting individual property rights in favor of the common good, provided any measures are designed to achieve a clear social objective, are not based on arbitrary or discriminatory considerations, and respect fair procedures. In addition, we note that the courts have been particularly deferential to Oireachtas in taking steps to secure the common good in times of crisis. In Part II, we examine some of the Bills proposed in the Oireachtas over the last several years to address Ireland’s housing crisis and assess, in light of case law, the likelihood that they might have been found constitutional. Despite the wide deference shown by the courts to the Oireachtas in limiting property rights in favor of the public interest, we note that in response to these Bills, the Government has often declared itself to be acting on the basis of legal advice to the effect that radical housing reform would necessarily prejudice the individual property rights of landlords. This has meant that, in reality, the wide provision for legislating for the pressing needs of the public has been diminished in favor of prioritizing individual property rights. This does not correlate with the attitude espoused by the courts. We argue that there is little to suggest that the courts would view constitutional property rights as posing a barrier to radical housing reform, should appropriate safeguards be included. In Part III, we conclude that successive Governments have continued to rely on a narrow understanding of property rights case law to justify a constrained role for the State in the housing market. While this is a perfectly valid political preference, we suggest that it is not a constitutional principle.
几年来,爱尔兰一直受到住房危机的困扰。最近,越来越多的人呼吁举行全民公投,将住房权纳入宪法。不管这个提议的优点如何,它部分源于一种看法,即目前形式的宪法阻碍了Oireachtas采取激进措施来补救住房危机。相反,我们认为,宪法判例法的法律解释高估了法院以牺牲公共利益为代价保护个人财产权的程度。在第一部分中,我们概述了与宪法中财产权保护有关的判例法,并确定了一些关键原则。我们从对爱尔兰判例法的审查中得出的结论是,只要任何措施的目的是为了实现明确的社会目标,不是基于任意或歧视性的考虑,并尊重公平的程序,法院在限制个人财产权利以有利于共同利益方面,在很大程度上都遵循Oireachtas。此外,我们注意到,法院在危机时期采取步骤确保共同利益时特别尊重奥伊雷achtas。在第二部分中,我们研究了过去几年在奥里亚奇塔州提出的一些法案,以解决爱尔兰的住房危机,并根据判例法评估它们可能被发现符合宪法的可能性。尽管法院广泛尊重Oireachtas,限制财产权以支持公众利益,但我们注意到,在回应这些法案时,政府经常宣布自己是根据法律建议采取行动的,即激进的住房改革必然会损害房东的个人财产权。这意味着,在现实中,为公众的迫切需要而立法的广泛规定已经减少,而有利于优先考虑个人产权。这与法院所支持的态度无关。我们认为,如果包括适当的保障措施,几乎没有证据表明法院会将宪法财产权视为对激进的住房改革构成障碍。在第三部分中,我们的结论是,历届政府继续依靠对产权判例法的狭隘理解来证明国家在住房市场中的有限作用是合理的。虽然这是一个完全合理的政治偏好,但我们认为这不是宪法原则。

Euro Housing Market Co-Movement: Medium vs. Short-Term Cycles 欧洲房地产市场共同运动:中期与短期周期
Pub Date : 2020-11-08 DOI: 10.2139/ssrn.3727027
W. Miles
A lack of co-movement among the national housing markets in the euro monetary union makes the job of the ECB difficult. If markets are depressed in some countries, while booming in others, the ECB would be unable to create simultaneous loose and tight monetary conditions tailored to each national situation. Co-movement across national housing markets has thus been a topic of several previous studies. Most of these papers focused on business-cycle frequency dynamics. Medium term cycles, however, have been shown to play a more important role for long-run output and the financial cycle than short-term fluctuations. We examine both business cycle and medium-term components of housing in eight euro nations. We find that the medium cycle is more volatile than the business cycle component in all markets. This indicates the medium cycle plays a more important role for housing in the long-run than short-term fluctuations. We find, however, that there is greater co-movement among the medium cycles of different national housing markets than between the short-term fluctuations.

We also find that co-movement of short-term cycles did appear to spike subsequent to the euro’s adoption, but that this greater apparent integration did not persist, and short-term co-movement has fallen in recent years. Finally, although medium-term co-movement is for most countries higher than that of the business cycle frequency, this greater synchronization does not appear to be a function of the euro common currency itself.
欧元区国家房地产市场缺乏合作,这让欧洲央行的工作变得困难。如果一些国家的市场低迷,而另一些国家的市场繁荣,欧洲央行将无法根据每个国家的情况同时制定宽松和紧缩的货币政策。因此,全国住房市场的共同走势一直是之前几项研究的主题。这些论文大多集中在商业周期频率动力学上。然而,中期周期已证明对长期产出和金融周期比短期波动发挥更重要的作用。我们研究了八个欧元区国家的商业周期和住房的中期组成部分。我们发现,在所有市场中,中期周期比商业周期更不稳定。这表明中期周期对住房的长期影响比短期波动更大。然而,我们发现,不同国家住房市场的中期周期之间比短期波动之间存在更大的共同运动。我们还发现,短期周期的协同运动在采用欧元后确实出现了飙升,但这种更大的明显一体化并没有持续下去,短期协同运动近年来有所下降。最后,尽管对大多数国家来说,中期的同步波动高于商业周期的频率,但这种更大的同步似乎并不是欧元共同货币本身的作用。

Does Temporary Mortgage Assistance for Unemployed Homeowners Reduce Longer Term Mortgage Default? An Analysis of the Hardest Hit Fund Program 失业房主的临时抵押贷款援助能减少长期抵押贷款违约吗?重灾区基金项目分析

The substantial costs of foreclosures to individuals and society motivated nearly $40 billion in government subsidies to homeowners during the Great Recession. Most of these subsidies were in the form of permanent loan modifications with mixed evidence of effectiveness. This paper estimates the loan outcomes of an alternative form of mortgage subsidy that provided unemployed homeowners with temporary mortgage payment assistance, through the U.S. Department of Treasury’s Hardest Hit Fund (HHF). Our primary empirical strategy exploits the fact that some states were not eligible to offer an HHF program and that certain Metropolitan Statistical Areas (MSAs) encompass jurisdictions in both HHF and non-HHF states. We match HHF-assisted homeowners to otherwise similar non-assisted homeowners who lived in the same MSA but were not eligible for HHF assistance because they lived in a non-HHF state. By 48 months after the start of assistance, receipt of HHF is associated with a 28 percentage point reduction in the probability of default, which is a 49 percent reduction in the average default rate of 57 percent. In support of the liquidity hypothesis, we find that the HHF effect is not driven by a reduction in mortgage balance, which only occurs for about 10 percent of HHF borrowers. Further, the effect is larger for borrowers who were underwater on their mortgages at the time of assistance.
丧失抵押品赎回权给个人和社会带来的巨大成本促使政府在大衰退期间向房主提供了近400亿美元的补贴。这些补贴大多是永久性贷款修改的形式,其有效性证据好坏参半。本文估计了另一种形式的抵押贷款补贴的贷款结果,该补贴通过美国财政部的重灾基金(HHF)向失业房主提供临时抵押贷款支付援助。我们的主要经验策略利用了一些州没有资格提供HHF项目的事实,以及某些大都市统计区(MSAs)涵盖了HHF和非HHF州的司法管辖区。我们将HHF援助的房主与生活在同一MSA但由于生活在非HHF状态而没有资格获得HHF援助的类似非援助房主进行匹配。在援助开始48个月后,收到HHF与违约概率降低28个百分点相关,即平均违约率(57%)降低49%。为了支持流动性假设,我们发现HHF效应不是由抵押贷款余额减少驱动的,抵押贷款余额减少只发生在约10%的HHF借款人身上。此外,对于那些在获得援助时抵押贷款资不抵债的借款人来说,这种影响更大。

The Anatomy of Collateralized Loan Obligations: On the Origins of Covenants and Contract Design 贷款抵押债务剖析:契约的起源与契约设计
Pub Date : 2020-10-27 DOI: 10.2139/ssrn.3740092

This paper provides a dissection of the Collateralized Loan Obligation (CLO) market and examines the significance of covenants in facilitating the provision of credit. Since the Great Financial Crisis of 2008, the leveraged loan market has witnessed unprecedented growth. CLOs play an increasingly central role in the provision of credit to corporations, holding as much as 75% of all new institutional leveraged loans, as reported in 2019. The rise of the leveraged loan and CLO markets have attracted the attention of central banks which have been concerned with both the growth of the market and the opaque nature of interconnections between intermediaries, leveraged borrowers, and investors. Despite their increasing importance, little is understood about CLO intermediaries. In this paper, I describe the agency frictions inherent in the CLO market, and discuss how optimal contracts are derived with covenants that curtail such frictions. In addition, I describe the general macroeconomic milieu that has facilitated the rapid growth of the CLO market as well as recent changes that have developed. Understanding the structural aspects and dynamics of CLOs intermediaries, situated between investors and loan syndicates, is paramount for analysis of the innards of the market, the role of covenants, and developing insights into the shadow banking sector as well as other securitizations.
本文对贷款抵押债券(CLO)市场进行了剖析,并考察了契约在促进信贷提供方面的意义。自2008年金融危机以来,杠杆贷款市场出现了前所未有的增长。clo在向企业提供信贷方面发挥着越来越重要的作用,据2019年的报告,clo占所有新增机构杠杆贷款的75%。杠杆贷款和CLO市场的兴起引起了各国央行的注意,它们一直关注市场的增长以及中介机构、杠杆借款人和投资者之间相互联系的不透明性质。尽管它们越来越重要,但人们对CLO中介机构知之甚少。在本文中,我描述了CLO市场中固有的代理摩擦,并讨论了如何从减少这种摩擦的契约中衍生出最优合约。此外,我还描述了促进CLO市场快速增长的宏观经济环境,以及最近发生的变化。了解位于投资者和贷款辛迪加之间的clo中介机构的结构方面和动态,对于分析市场内部、契约的作用以及深入了解影子银行部门和其他证券化至关重要。

Since the Great Financial Crisis of 2008, the leveraged loan market has witnessed unprecedented growth. CLOs play an increasingly central role in the provision of credit to corporations, holding as much as 75% of all new institutional leveraged loans, as reported in 2019. The rise of the leveraged loan and CLO markets have attracted the attention of central banks which have been concerned with both the growth of the market and the opaque nature of interconnections between intermediaries, leveraged borrowers, and investors. Despite their increasing importance, little is understood about CLO intermediaries. In this paper, I describe the agency frictions inherent in the CLO market, and discuss how optimal contracts are derived with covenants that curtail such frictions. In addition, I describe the general macroeconomic milieu that has facilitated the rapid growth of the CLO market as well as recent changes that have developed.

Taming the Housing Crisis: An LTV Macroprudential Policy 驯服住房危机:LTV宏观审慎政策

This paper develops a DSGE framework featuring a heterogeneous housing market, endogenous default, and a banking sector. We find that the idiosyncratic mortgage risk shock plays an important role in explaining the fluctuations of house prices during the mid-1980s and the years leading up to the financial crisis. The same shock is also one of the main driving forces of household loans. By placing an occasionally binding constraint on the loan-to-value ratio, we find that the overheating of the housing economy in the early 2000s and the subsequent crash could have been alleviated, if authorities had adopted such a macroprudential policy measure. A welfare comparison indicates that the maximum loan-to-value policy is preferable over an augmented Taylor rule that responds to house price growth.
本文开发了一个以异质住房市场、内生违约和银行部门为特征的DSGE框架。我们发现,特殊抵押贷款风险冲击在解释20世纪80年代中期和金融危机前几年的房价波动方面发挥了重要作用。同样的冲击也是家庭贷款的主要推动力之一。我们发现,如果当局采取了这样的宏观审慎政策措施,通过偶尔对贷款与价值比率施加约束性约束,21世纪初房地产经济的过热以及随后的崩盘本可以得到缓解。一项福利比较表明,最大贷款价值比政策比响应房价增长的增强泰勒规则更可取。

The Misallocation in the Chinese Land Market 中国土地市场的错配
Pub Date : 2020-10-21 DOI: 10.2139/ssrn.3716540

This paper proposes a spatial equilibrium model to quantify welfare losses from land market distortions in China. In the model, heterogeneous firms in a variety of sectors choose their locations across regions with costly trade, frictional labor migration, and land market distortions. We match land transaction and firm-level survey data to estimate land market distortions for firms. Misallocation arises when similar firms are faced with land prices that effectively prevent productive firms from establishing in large cities where they can benefit from agglomeration forces and access to higher productivity. Our framework incorporating land market distortions also helps clarify the mystery of China’s undersized cities, a phenomenon noted by Au and Henderson (2006) and Chauvin et al. (2017). Our estimates suggest large negative effects of land policies on the economic welfare in China. We end with a counterfactual exercise that suggests that a coordinated land and labor migration reform would generate welfare gains and reduce regional inequality
本文提出了一个空间均衡模型来量化中国土地市场扭曲造成的福利损失。在该模型中,不同行业的异质企业在贸易成本高、劳动力迁移摩擦和土地市场扭曲的地区之间选择其所在地。我们将土地交易和企业层面的调查数据相匹配,以估计土地市场对企业的扭曲。当类似的企业面临土地价格时,土地价格有效地阻止了生产性企业在大城市落户,而在大城市,它们可以从集聚力量中受益,并获得更高的生产率。我们纳入土地市场扭曲的框架也有助于澄清中国小规模城市的奥秘,Au和Henderson(2006)以及Chauvin等人(2017)指出了这一现象。我们的估计表明,土地政策对中国的经济福利产生了巨大的负面影响。我们以一个反事实的练习结束,该练习表明,协调的土地和劳动力迁移改革将产生福利收益并减少地区不平等
