Measuring housing affordability: Looking beyond the median

We draw a distinction between the concepts of purchase affordability (whether a household is able to borrow enough funds to purchase a house) and repayment affordability (the burden imposed on a household of repaying the mortgage). We operationalize this distinction in the context of a new methodology for constructing affordability measures that draws on the value-at-risk concept and takes account of the whole distribution of household income and house prices rather than just the median. Empirically we find that the distinction between purchase and repayment affordability can be pronounced. In the Sydney prime mortgage market over the period 1996–2006, repayment affordability deteriorated very significantly while purchase affordability remained quite stable. This difference can be attributed to the loosening of credit constraints in the mortgage market which it seems has carried through primarily into higher house prices rather than an improvement in purchase affordability. We also show how median house-price-to-income ratio measures of affordability can be extended to take account of the whole distribution of income and house prices, and how as a result of differential skewness in the house price and income distributions the housing affordability problem may be significantly worse for lower income households than suggested by standard median measures.     

A micro view on home equity withdrawal and its determinants: Evidence from Dutch households

For most households, home ownership is the largest wealth component that has become more accessible through innovation and deregulation in mortgage markets. This paper studies the factors driving home equity withdrawal (HEW) at the household level using Dutch survey data. In the Netherlands, house prices were growing fast and mortgage expenses are to a large extent tax deductible. Expectations and perceptions do seem to play an important role in HEW. Withdrawers tend to be more positive about house price developments and – although having lower income – less concerned about their future economic situation. HEW can have a significant impact on both households and the economy, with most of the equity released being reinvested in the housing sector and only a small share used to finance consumption expenditure.     

Why Do Mortgage Markets Matter?

1999 saw the return of large scale mortgage equity - ie mortgage borrowing to finance consumption rather than house purchase - for the first time for a decade. Recent developments of the OEF macroeconometric model of the UK economy have focused on the determination of mortgage lending, looking in particular at the impact of downpayment constraints - ie the deposit borrowers have to put down when they buy a house. In this article, Geoffrey Meen uses this model to analyse the effects of mortgages on: (i) the cycle in the UK housing market at a national level; (ii) regional house price differentials; and (iii) aggregate savings and consumer behaviour.     

Negative equity and wages

We examine the relationship between housing equity and wage earnings using nine waves of the national American Housing Survey from 1985 to 2003. Employing a rich set of time and place controls, a synthetic mortgage instrumental variable strategy, and a first difference estimator we find that people underwater on their mortgage command a significantly lower wage than other homeowners. The finding survives a number of robustness checks for reverse causality and unobserved heterogeneity. We also explore other determinants of “house lock” including loss aversion, a low existing mortgage interest rate and property tax assessment caps, but do not find these factors mitigate the effect of negative equity on wages.     

Economic Outlook 1991 – 1995: The London Business School with Gower Publishing: THE HOUSING MAFUCJIT IN RECESSION : A PAINFUL ADJUSTMENT TO ERM DISCIPLINE

We, together with almost every other commentator on the UK housing market, forecast a recovery of house prices and turnover during 1991. These hopes have been disappointed. This Forecast Release addresses some of the questions raised by this prolonged weakness in the housing market. Why did we, and so many others mis-judge the outlook for house prices and housing investment? Are there structural problems, especially those associated with the adjustment to the inflationary discipline of the E M, which are preventing a revival? When will recoverly take place and can there ever be a house-price boom similar to 1984–1988 again? One reason for the unanticipated weakness of the housing market is the growing problem of mortgage arrears and possessions. This can be expected to produce at least some temporary weakening of house prices as a reaction to the current volume of empty properties being put onto the market. There is a more fundamental reason for the current weakness of house prices. Unlike previous house price booms and busts, the present recession offers no relief to the hard-pressed borrower in the form of a rapid inflation of average earnings. Difficulties with mortgage repayments, for highly indebted households, are set to continue for some time. These lessons are not being lost, either on prospective purchasers who are’ being discouraged from taking out substantial mortgages in relation to their incomes, or on mortgage lenders who are being much more prudent in the setting of mortgage to- income and mortgage-to-price limits. The result is a long overdue adjustment of British attitudes towards own er-occupation.     

主房反向抵押贷款支持老年人收入拓展

Using a decision tree to analyze mortgage borrower decision behavior and values concerning interest rates and house prices

In reality, mortgage borrowers are more seriously concerned with the current mortgage boundary (i.e. option exercise) value than with the current option value (i.e. expected present value of the prospective option exercise value). Hence, by combining a simulation framework and a decision tree, the terminations of mortgage behavior can be classified forward but not backward as by the binomial lattice. After simulating 5000 projections for both Taiwan house prices and interest rates, as well as computing for current mortgage boundary values obtained by modifying Ambrose and Buttimer ( 2000 ) to step through the mortgage decision tree, the result shows that the prepayment is affected by rising interest rate volatility. Moreover, the delinquency and the reinstatement are affected by both rising interest rate and house price volatilities. However, due to the cost of delinquency and credit penalties, the foreclosure could not compete over the reinstatement when house prices and interest rates are in a high‐volatility situation. The reinstatement is encouraging for the borrowers. Copyright © 2010 John Wiley & Sons, Ltd.     

Extracting market information from equity options with exponential Lévy processes

Lévy processes have been successfully applied in the modeling of financial assets. Useful information such as implied volatility, skewness, and risk-preferences can be derived from market option prices. In this paper, we advocate using Esscher conjugate Lévy processes to estimate risk-neutral and empirical densities. More specifically, we employ the exponential Meixner and NIG processes to calculate in closed form the pricing kernel in the equity market and then study the evolution of equity market behavior between 2002 and 2010. Our empirical analysis using S&P 500 options shows that the risk preferences of equity investors were signalling an anomaly in the market well before the subprime prime mortgage crisis (August 2007) and the crisis of confidence that followed, anticipating the downfall in equity markets in 2008, but then returning to normal levels in 2009.     

Payment shock and mortgage performance

The effect of payment shocks on subprime hybrid ARM mortgage prepayment and delinquency is examined. Using loan level data from private label securities, we modeled the effects of payment shocks on mortgage performance. Our study provided interesting empirical results in three main areas: First, we addressed the effect of payment shocks on subsequent mortgage delinquency. Second, we studied how the effect of payment shocks varies and decays over time. Third, we disentangled the impact of payment shocks based on the reason for the shocks: payment shock due to the expiration of a teaser rate (i.e. “teaser shock”) versus the payment shock due to index rate changes at the time of reset (i.e. “market rate shock”).We find that the effect of payment shock on loan performance varies by the delinquency status of the loan at the time of the shock. That is, the payment shock has the most significant effect on “current” loans rather than loans already in delinquency. Also of note, we find that the effect of a payment shock decays only gradually over time. We find that the impact of “teaser shocks” and “market rate shocks” on mortgage performance do not differ substantially, even though teaser shocks may be somewhat more predictable than market rate shocks. This suggests that either subprime ARM borrowers did not fully understand the product and the extent of the shock at the first reset date or that financially strapped borrowers used the product to speculate and were caught by the teaser shock when they were unable to refinance or sell (i.e. “flip”) their properties .The study suggests that any modification plan designed to eliminate potential payment shocks or to otherwise lower payments will be most effective for loans that are currently performing rather than loans that are already in delinquency.     

Spillover effects of subprime mortgage originations: The effects of single-family mortgage credit expansion on the multifamily rental market

The dramatic expansion in subprime mortgage credit fueled a remarkable boom and bust in the US housing market and created a global financial crisis. Even though considerable research examines the housing and mortgage markets during the previous decade, how the expansion in mortgage credit affected the rental market remains unclear; and yet, over 30 percent of all U.S. households reside in the rental market. Our study fills this gap by showing how the multifamily rental market was adversely affected by the development of subprime lending in the single-family market before the advent of the 2007/2008 subprime induced financial crisis. We provide evidence for a fundamentals based linkage by which the effect of an innovation in one market (i.e, the growth in subprime mortgage originations) is propagated through to another market. Using a large database of residential rental lease payment records, our results confirm that the expansion in subprime lending corresponds with an overall decline in the quality of rental payments. Finally, we present evidence showing that the financial performance of multifamily rental properties reflected the increase in rental lease defaults.     

Negative home equity,economic insecurity,and household mobility over the Great Recession

This paper uses data from the 2007–09 Survey of Consumer Finances panel to examine U.S. households’ decisions to move during the Great Recession and the role of negative home equity and economic shocks, such as job loss, in these decisions. The recession's effects are nonetheless apparent in the notable fraction of homeowners who moved involuntarily due to, for example, foreclosure. Many involuntary moves appear to stem from a combination of negative home equity and adverse economic shocks rather than negative equity alone. Homeowners with both negative equity and economic shocks were substantially more likely to have moved between 2007 and 2009 and to have moved involuntarily. The findings suggest that, analogous to the double-trigger theory of default, the relationship between negative equity and household mobility varies with households’ exposure to adverse shocks.     

Factors affecting delinquency of household credit in the U.S.: Does consumer sentiment play a role?

In this study, we provide both theoretical and empirical evidence on the determinants of household loan delinquency for home ownership, credit card and auto loans for the U.S. states in a panel framework over a period from 2003 through 2017. In particular, we examine the impact of consumer sentiments on loan delinquency rates. We show that improved current consumer sentiment significantly induce lower mortgage, credit card and automobile loan defaults in the American states subdivided into four different regions. We also find that the higher overall and expected consumer sentiment raise loan delinquencies. Implicit in this finding is the apparently excessive and inappropriate expansion of loans in the U.S. economy in the face of consumers’ optimism, which in turn, provides an intuitive understanding of the circumstances that could precede a depression or outbreak of anomalies in the financial sector. Our general findings further exhibit significant positive effect of unemployment rate and mostly adverse effect of per capita income on mortgage and automobile loan delinquency rates. The results provide some compelling evidence with regard to the effect of consumer confidence on household credit delinquency rates across various states in the U.S. and are robust to alternative measures of income and mortgage rates.     

Macroeconomic implications of mortgage loan requirements: an agent-based approach

It is a well-known fact that the housing market, with its associated mortgage securities, plays a crucial role in modern economies. The recent crisis of 2007, triggered by the U.S. real estate bubble, confirms this key role and suggests the importance of regulating mortgage lending. This paper investigates these issues by designing a housing market with a linked mortgage lending instrument in the Eurace agent-based model. Our results show that the presence of a housing market in the model has relevant macroeconomic implications, driven mainly by the additional amount of endogenous money injected into the economy by new mortgages. This additional money generally helps to support and stabilize aggregated demand, thus improving the main economic indicators. However, if the regulation of mortgage lending is too lax, involving an increase in the debt-service-to-income ratio (DSTI), then the additional supply of mortgages no longer enhances macroeconomic performance, and the stability of the economic system is undermined. Based on a number of recent discussions, a regulation of stock control that targets households’ net wealth (a stock), rather than income (a flow) is designed and analyzed. The results show that regulation of stock control can be combined effectively with DSTI to increase the stability of the housing market and the economy as a whole. Interestingly, the regulation based on stock control also directly affects mortgage distribution among households, avoiding excessive concentration. From a policy perspective, our results suggest that the use of a mild flow control regulation, coupled with a stricter stock control measure, fosters sustainable growth and eases first-time buyers access to the housing market, encouraging homeownership.

     

Young people living as couples: How women's labour supply is adapting to the crisis. Spain as a case study

In this paper, we focus on the effects of the Great Recession on the decisions of young women regarding their labour supply. Considering the profound effect of the economic recession on the Spanish labour market, and in particular on the labour supply of young people, the focus of the empirical part of this paper is on Spain. Using EU-SILC 2007 and 2012 micro data for Spain, the labour supply models of women are estimated by age group, with a particular focus on the 20 to 29 and 30 to 39 age bands, in order to establish how young women living in couples exhibit different labour supply propensities according to their partner's labour market status. Correction is made for the non-random selection of women living in couples in the younger age groups. This first analytical step reveals a negative effect on the likelihood of forming a new household in the context of precarious employment conditions. Analytical results regarding the labour supply of women by age group confirmed a discouraging effect of young children on the labour supply of the youngest mothers, as well as a positive effect from being the owner of a house purchased under mortgage.The literature shows that different effects can be at work within the crisis: an added worker effect (AWE), which is countercyclical labour supply behaviour involving an increase in individual labour supply in response to transitory shocks in the partner's earnings, and a procyclical discouraged worker effect. The resulting estimations of the present study suggest an AWE in 2012 for young women living in couples. While in 2012 the discouragement effect was only prevalent for women over 40, in 2007 it was also prevalent among younger women. Women's higher propensity to enter the labour market when their partner becomes unemployed or is persistently unemployed, coupled with their likelihood to be inactive in the presence of young children, would suggest a need for labour market policies targeted towards young women. Childcare facilities could mitigate the latter effect and produce a more continuous work profile, avoiding the negative effects of work experience interruptions on labour supply during the female lifecycle.

Borrowing Constraints and Credit Demand in a Developing Economy

This paper investigates the determinants of credit demand in the presence of borrowing constraints in a developing economy. We model the determinants of observed debt for Chilean households while accounting for selection bias and the endogeneity of their income and specific household assets. Using a novel Chilean dataset, we estimate the relationship between household characteristics and consumer and mortgage debt. We find substantial differences in the nature of these relationships across the types of debt. For example, we find that the income elasticity for consumer debt is greater than 1 whereas for mortgage debt it is not. The results suggest the increased availability of credit, combined with the aging of the Chilean population, is likely to drastically change the distribution and level of Chilean debt. These findings are particularly relevant for other developing economies currently experiencing rapid income and debt growth. Copyright © 2015 John Wiley & Sons, Ltd.     

Subprime lending and the housing bubble: Tail wags dog?

The cause of the “housing bubble” associated with the sharp rise and then drop in home prices over the period 1998–2008 has been the focus of significant policy and research attention. The dramatic increase in subprime lending during this period has been broadly blamed for these market dynamics. In this paper we empirically investigate the validity of this hypothesis vs. several other alternative explanations. A model of house price dynamics over the period 1998–2006 is specified and estimated using a cross-sectional time-series data base across 20 metropolitan areas over the period 1998–2006. Results suggest that prior to early 2004, economic fundamentals provide the primary explanation for house price dynamics. Subprime credit activity does not seem to have had much impact on subsequent house price returns at any time during the observation period, although there is strong evidence of a price-boosting effect by investor loans. However, we do find strong evidence that a credit regime shift took place in late 2003, as the GSE’s were displaced in the market by private issuers of new mortgage products. Market fundamentals became insignificant in affecting house price returns, and the price-momentum conditions characteristic of a “bubble” were created. Thus, rather than causing the run-up in house prices, the subprime market may well have been a joint product, along with house price increases, (i.e., the “tail”) of the changing institutional, political, and regulatory environment characteristic of the period after late 2003 (the “dog”).     

Credit rationing, race, and the mortgage market

This study applies microdata from the 1983 Survey of Consumer Finances to evaluate the effects of borrower race and default risk in mortgage lending. The empirical analysis is based on a probit model of whether borrowers obtain FHA or conventional mortgages; the former are fully insured and are characterized by easier downpayment constraints, but are typically more expensive. Hence, households borrowing through the FHA will tend to be credit constrained in the conventional market. Results of the analysis indicate that variables which proxy lender concerns about default risk and cost have an important effect on the type of loan borrowers obtain. Empirical estimates also suggest that minority households are significantly less likely to obtain conventional financing than whites, even after controlling for various proxies of default risk. These results suggest that race effects in mortgage lending may persist for reasons unrelated to borrower default risk.

Some Truths about Ostriches: Who Doesn't Prepay Their Mortgages and Why They Don't

Prepayment estimation is essential in forecasting expected mortgage cash flow patterns. Accordingly, mortgage and mortgage-backed security prices are highly dependent on prepayment assumptions. Yet borrower prepayment behavior appears to be highly irrational, in the sense that many borrowers prepay their mortgages when it is not optimal to do so and fail to prepay their mortgages when the prepayment option is substantially in the money. In this paper, we explore the latter phenomenon, using a large data set of loans originated during the relatively high-rate 1980s that have failed to prepay by year-end 1996. As a control group, we examine similar loans that did prepay during the refinancing boom of 1993. By coupling Case–Shiller house price index information at the zip-code level, we can analyze the effect of broader housing market trends, especially housing appreciation, on borrower prepayment behavior. Although housing prices did decline significantly during the late 1980s and early 1990s in many areas of the United States, we find evidence that only about 25% of non-refinancing households might have been constrained by declining collateral values. Household demographic characteristics may provide some further explanation for this apparently non-optimizing behavior; however, we do not have a complete explanation.
