Borrower Attitudes Toward Alternative Mortgage Instruments*

Much of the existing literature on homeownership assumes that financial markets work well enough to allow households to translate permanent income into effective demand. However, transaction costs, imperfections, and uncertainties all constrain the markets' operation so that people are often forced to choose a quantity of housing stock that diverges from their desired consumption level. Instead of being able to borrow against future income for the down payment or to make monthly payments in a pattern that matches future income, young families in their early years may be constrained from purchasing the size house they desire, and older households may remain in homes larger than they need. In light of these market imperfections, housing and tenure decisions depend not only on permanent income and the relative price of housing services, but also on such mortgage parameters as monthly payment patterns, down payment, and rate of equity accumulation. Models of the demand for housing and homeownership described in the existing literature do not include these parameters of mortgage finance. Mortgage terms are important factors in housing consumption and investment decisions. Because the standard mortgage no longer seems appropriate for all households under all economic conditions, the extent to which alternative mortgage instruments meet the requirements and preferences of different segments of the market becomes an important issue.     

Choice of Mortgage Contracts: Evidence from the Survey of Consumer Finances

This study revisits the empirical question of the determinants of the choice between fixed‐ and adjustable‐rate mortgages using data from the Survey of Consumer Finances that overcome some of the data limitations in previous studies. The results from a logit model of mortgage choice indicate that pricing variables and affordability are important considerations. We also find that factors, such as mobility expectations, income volatility and attitudes toward financial risk largely influence mortgage choice, with more risk‐averse borrowers preferring fixed‐rate mortgages. For households that are less risk averse, the mortgage type choice decision is less sensitive to pricing variables and income volatility, and affordability factors are not significant. These findings provide empirical support that underscores the importance of attitudes toward risks in mortgage choice.     

Alternative Lending Channels and the Crisis in U.S. Housing Markets

To what degree has the development of alternative mortgage funding channels promoted the recent boom and bust in U.S. housing markets? Past research examined whether Alt‐A and subprime market shares are correlated with the housing bubble. This article expands the analysis to include the share of specific “alternative” lending terms and finds that the shares of interest‐only and negative amortization loans are important factors in explaining the housing bubble. This result suggests that research on the housing market bubble should focus on the impacts of loan contract terms rather than loan channel.     

Unobservable Risks in Mortgage Contract Choice

This study proposes a lifetime utility maximization model where borrowers choose optimal mortgage bundles including mortgage type, loan‐to‐value and loan size to maximize their allocation of limited budgets between housing and nonhousing consumptions. The model predicts that the mortgage bundle choices by borrowers of different income and risk attributes explain significant variations in the ex post default risks of the borrowers. The empirical tests using sampled mortgages pooled in nonagency residential mortgage backed securities support the hypothesis that the optimal choice of mortgage bundles reveals hidden risk factors of borrowers, which, if ignored, could lead to misjudgment of ex post default of borrowers.     

Amenity‐Based Housing Affordability Indexes

The recent slump notwithstanding, substantial increases in house prices in many parts of the United States have served to highlight housing affordability for moderate‐income households, especially in high‐cost, supply‐constrained coastal cities such as Boston. In this article, we develop a new measure of area affordability that characterizes the supply of housing that is affordable to different households in different locations of a metropolitan region. Key to our approach is the explicit recognition that the price/rent of a dwelling is affected by its location. Hence, we develop an affordability methodology that accounts for job accessibility, school quality and safety. This allows us to produce a menu of town‐level indexes of adjusted housing affordability. The adjustments are based on obtaining implicit prices of these amenities from a hedonic price equation. We thus use data from a wide variety of sources to rank 141 towns in the greater Boston metropolitan area based on their adjusted affordability. Taking households earning 80% of area median income as an example, we find that consideration of town‐level amenities leads to major changes relative to a typical assessment of affordability.     

Distributional Consequences of Alternative Mortgage Instruments

One of the major factors hindering the introduction of alternative mortgage instruments is the possibility of adverse consequences to certain groups of households seeking to obtain credit for homeownership. This study examines this issue through an analysis of cross-sectional household data obtained from the 1970 Survey of Consumer Finances. Using multiple regression analysis, a series of structural demand models are derived and estimated. These models relate the probability of homeownership, levels of housing consumption, mortgage credit usage, and downpayment to income, assets, and other socioeconomic variables, to variables representing the relative price of housing and homeownership, and to certain variables representing the present value and cash flow costs of mortgage credit. Several mortgage-related variables are found to be influential in housing demand decisions. These models are then used to simulate alternative instrument introduction. The graduated-payment and price-level adjusted mortgages are predicted to be superior to the current instrument of mortgage finance in encouraging homeownership, housing consumption, and the use of mortgage credit among all household classes. The standard variable-rate mortgage, especially one tied to a short-term interest rate, is predicted to be inferior to the standard instrument, with the most adverse impacts upon lower-income, young, elderly, and black households.     

Supermarket contracts and smallholder farmers: Implications for income and multidimensional poverty

Food systems in developing countries are changing rapidly with a growing role of modern supermarkets. Supermarkets influence supply chains and the way agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent and high-quality supply. One important question, which is addressed here, is whether smallholder farmers benefit from supermarket contracts. Previous studies address this question, but mostly focus on income effects without exploring implications for other dimensions of household welfare, such as nutrition, health, or housing conditions. Moreover, most existing studies rely on cross-section data. We add to the literature by analyzing effects of supermarket contracts on income and multidimensional poverty using three rounds of panel data collected from smallholder vegetable farmers in Kenya and econometric models with household fixed effects. On average, supermarket contracts increase household income by over 40%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. However, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.     

Commuting with Lost Housing Services as the Opportunity Cost

In American metropolitan areas, households are highly mixed by income with higher average incomes at greater distances from downtown. Also, suburbs attract families with children, while poor households and small households with young heads select sites close to the commercial core. These empirical observations and others are predicted by this standard model of a monocentric city with three major modifications. Time at work is controlled by employers, not employees. Households with more members at home consume in the same house more housing services. Finally, lot prices need not be proportional to area. In the resulting equilibrium, households are mixed by income and separated by family size. This contrasts with classic urban models where households are separated only by their workers' wage rates.     

Mortgage Default and Prepayment Risks among Moderate‐ and Low‐Income Households

Using a unique sample of community reinvestment loans, we study the propensity of very low‐income households to terminate a mortgage and compare it to the outcomes for low‐income and moderate‐income households. The results indicate that, even within moderate‐ and low‐income segments, lower or very low income is associated with higher default and lower prepayment probabilities. In addition, depending on how low the borrower's income is, classic determinants of loan termination such as credit scores, the amount of equity in the home and local labor market conditions can have different impacts on default and prepayment probabilities.     

The Borrower's Perceived Risk in Mortgage Choice

We investigate how borrowers perceive the risk in the adjustable rate mortgage (ARM) versus fixed rate mortgage (FRM) choice. We develop a mortgage choice model where the coefficient on the long‐term bond risk premium is conditional on the borrower's perceived risk. We show that the perceived risk fluctuates over time according to the short‐term interest rate level and housing market conditions. We find that when the short‐term rate level is high (low), the borrowers perceive low (high) risk of a short‐term rate rise, thus opting for ARMs (FRMs). Also, during a down housing market they become more risk‐averse perceiving higher risk in choosing ARMs. The perceived risk level alters the borrowers’ sensitivity to the long‐term bond risk premium.     

Finnish Homes—Through Passages or Traps?

This is a study of tenure choice, housing demand and mobility in the submarkets of the Helsinki metropolitan area. The empirical analysis is based on data on households, type of tenure, housing characteristics and mobility for a sample of Helsinki residents at the end of 1980s. According to our results the probability of owning is affected not only by user costs of alternative tenure forms but also by permanent income and demographic variables. Results from the tenure specific housing demand models indicate that there are non-neutralities in the housing markets. Permanent income elasticities of housing demand are clearly positive in owner-occupied sector and systematically higher than in the rented sector. The demand for owner-occupied housing depends very strongly on the age of the household head. User cost per housing unit affects housing demand negatively in both tenure forms. Effective demand is greater in private housing sector. The results suggest that owner-occupied living is preferred with heavily subsidized households the least likely to move. In the rental sector, where the probability of moving is higher, it is also true that the most heavily subsidized households are the least likely to move.     

Mortgage Borrower Repayment Behavior: A Microeconomic Analysis with Canadian Adjustable Rate Mortgage Data

In this paper we estimate a model of mortgage borrower behavior using micro-level data on Canadian borrowers with rollover mortgages—a form of adjustable-rate mortgage. Our results suggest that the probability of default rises with a decrease in housing equity and an increase in the mortgage contract rate; however the size of these changes is relatively small. They also show that partial prepayment is sensitive to fluctuations in the rates of return from investing in housing versus other assets. For the United States experience, our results suggest that, relative to fixed-rate mortgage borrowers, adjustable-rate mortgage borrowers are more likely to default and less likely to prepay.     

Estimation of Mortgage Defaults Using Disaggregate Loan History Data

This paper addresses, theoretically and empirically, the structure of influences affecting the default option in mortgage contracts. A formal theoretical model recognizes that a number of loan and non-loan related effects beyond equity in the unit could influence the default decision. These include 1) payment levels relative to income, which could displace other investment opportunities or cause a need for borrowing or sale to meet mortgage obligations; 2) current and expected neighborhood and housing market conditions, in particular the expected relative rate of appreciation of the unit and the relative cost of homeownership; 3) economic conditions; 4) wealth; 5) borrower characteristics proxying for variability in income or "crisis" events; as well as 6) transactions costs incurred upon default. Estimates of the model making use of a micro-level sample of individual loan histories over a twelve year period, supplemented by longitudinal census and economic information, find a number of these "other" effects important. Simulations find several of them to dominate the equity effect on default and to help explain why some households with zero or negative equity may not default, while others with positive equity may. The implications of these results for appropriate specification of the pricing model describing the default option and for appropriate underwriting of AMIs are noted.     

Are Adjustable‐Rate Mortgage Borrowers Borrowing Constrained?

Past research argues that changes in adjustable‐rate mortgage (ARM) payments may lead households to cut back on consumption. These outcomes are more likely if ARM borrowers are borrowing constrained, and we show in this article that ARM borrowers exhibit attitudes toward borrowing and behavior that are consistent with being borrowing constrained. Although the demographic and financial characteristics of ARM and fixed‐rate mortgage (FRM) borrowers are somewhat similar, ARM borrowers differ from FRM borrowers in their uses of credit and attitudes toward it. In addition, we find the consumption growth of households with an ARM is more sensitive to past income than the consumption growth of other households, suggesting the ARM borrowers may be subject to borrowing constraints that hinder their ability to smooth consumption.     

The Impact of Housing Vouchers on Mobility and Neighborhood Attributes

This article examines the effect of receiving a housing voucher on the mobility and neighborhood attributes of low‐income households. Housing policy has shifted toward vouchers in lieu of public housing projects to allow households to move away from high‐poverty areas. We use administrative records collected from an experiment to examine this issue. We find that households moved immediately after receiving the subsidy but did not relocate to lower poverty neighborhoods until several quarters later. Our findings suggest that recipients initially lease in nearby units to secure the subsidy, while continuing to search for housing in lower poverty neighborhoods.     

The dynamics of livelihood diversification in post-famine Ethiopia

Based on data for almost 300 households this paper explores associations among income diversification, household perceptions of livelihood risks, and changes in consumption outcomes across two points in time in post-famine Ethiopia. Four key questions are addressed: i) To what extent did households emerging from the famine period with relatively higher income and calorie consumption levels also have a more diversified income base?; ii) Was higher income diversification in 1989 associated with higher income and consumption levels by 1994?; iii) Which households increased their share of income from non-cropping activities most during the inter-survey years?; and iv) Did household heads perceive a lack of non-farm income activities to be an important risk factor in famine vulnerability? We find that wealthier households tended to have more diversified income streams; those initially more diversified subsequently experienced a relatively greater increase in both income and calorie intake; households with a greater concentration of assets were more likely to fall in their relative outcome ranking (as were female-headed households); and, initially less diversified households subsequently realized greater gains in income diversification. We also find suggestive evidence that personal perceptions of risk factors guided subsequent diversification decisions.     

How Does Mortgage Debt Affect Household Consumption? Micro Evidence from China

The high growth rate of mortgage debt in various emerging and developed economies has captured headlines following the financial crisis. In this article, we investigate how mortgage debt impacts household consumption behavior and various components of household consumption. Utilizing comprehensive household survey data from China, we show that households with a mortgage consume a higher portion of income than households without a mortgage. This is in line with the argument that having a mortgage reduces the uncertainty that the household faces regarding how much to save each month in order to be able to own a house, and this reduced uncertainty leads to lower monthly savings for the purpose of buying a house. We also find that among households with a mortgage, those who spend a larger share of their income on mortgage payments spend less on consumption, reflecting the crowding out effect of mortgage payments on household consumption. Furthermore, we show that a government policy of decreasing the maximum loan‐to‐value ratio has a significant impact on households’ consumption. The article offers the first evidence of the impact of growing mortgage debt on the consumption behavior of households, and will have implications for government policies that encourage mortgage borrowing.     

The Accuracy of Senior Households’ Estimates of Home Values: Application to the Reverse Mortgage Decision

Using a unique data set of more than 14,000 senior homeowners in the United States, this study compares self‐assessed home values to arm's length contemporaneous appraisals. In a sample of seniors who received counseling for a reverse mortgage, the absolute value of the assessment error averages 18.9% of appraised value and it is biased upwards by 13.4%. When adjusted to reflect the general population of seniors, the size and bias of the average error fall to 16.1% and 4.2%. Both the bias and the size of the error tend to be lower for households with higher income and credit scores but it is greater for black households. In our sample period of 2009–2011, house prices were falling. The greater the rate of price reduction, the greater is the upward bias and size of the assessment error. When seniors who applied for a reverse mortgage learn that they overvalued their home, their probability of closing the loan falls.     

Information Externalities,Neighborhood Characteristics and Home Mortgage Pricing and Underwriting

Theories of rational redlining suggest thinness in housing markets should lead to greater uncertainty in house price appraisals, increasing mortgage denial rates or pricing. Empirical tests found support for this theory in mortgage underwriting using 1990s data. Using 2006 data and bank‐specific regression models, we revisit this topic in light of two developments leading to the recent mortgage bubble: the widespread securitization that allowed banks to shift loan risk to investors and the advent of risk‐based pricing. Consistent with expectations, we find that information externalities have become economically very small and have shifted from underwriting to pricing decisions.     

Price Expectations,Distressed Mortgage Markets and the Housing Wealth Effect

Using a unique combination of regulatory and survey microdata, we examine the importance of the life cycle theory of consumption in estimating housing wealth effects for the Irish mortgage market. Since the recent financial crisis, this market has experienced substantial house price declines and negative equity. Thus, house price expectations are likely to be important in influencing housing wealth effects. We find a positive correlation between consumption and changes in housing wealth among our sample of mortgaged Irish households. Furthermore, we find that this positive association only exists when housing wealth changes are perceived to be of a permanent nature.
