Residential Mortgage Markets and the Cost of Mortgage Funds

Early federal housing finance policy appears to have been largely directed at making mortgages more marketable. The creation of FHA, FNMA and FHLMC were designed to homogenize the mortgage instrument and to develop a secondary market for it. Apparently because of a lack of demand for marketability by investors, extensive trading of mortgages has not developed. Nonetheless, the fantastic growth in mortgage pools (as well as the unanticipated growth in FNMA holdings) has increased competition in the supplying of some intermediation functions (mortgage bankers have greatly expanded originations and servicing), has improved interregional flows of mortgage funds, and has given mortgage borrowers a greater access to capital markets generally. The principal result has been a decline in the mortgage rate relative to other market rates, although the inflation-triggered explosion in the demand for mortgage funds in recent years appears to be offsetting the impact of the growth in federal credit broadly defined.     

The Integration of Mortgage Markets and Capital Markets

In this paper, we develop a model to predict the impact of deregulation in the form of relaxing interest rate control on the integration between the mortgage credit market and the general credit market. The model is tested through the examination of the long-term Granger-like equilibrium relationship between mortgage interest rates and general interest rates in the pre-1980 regulated vs. the post-1980 deregulated periods. It is shown that the level of regulation, in the form of targeting general interest rate levels, contributes to the segmentation of the mortgage market from the capital market. To test this model, we compare the relationship between mortgage interest rates and general interest rates around 1980 where major control on interest rate levels in capital markets was lifted. Using Engle and Granger's procedure to overcome the estimation problem from nonstationarity in the interest rate series, we are able to find that the two interest rates were cointegrated after 1980 but not before. More importantly, it appears that the two markets were already integrated before the full development of the secondary mortgage markets between 1984 and 1987. Therefore, we conclude that the bulk of the integration between the mortgage and capital markets was completed as a result of the removal of interest rate controls around 1980, in contrast with previous studies that find integration occurred during the mid-1980s primarily as a result of the rapid development of the secondary mortgage markets.

The Demand and Supply of Mortgage Funds and Mortgage Loan Terms

The supply of and demand for residential mortgages has been the subject of much discussion in the literature. Many of these studies have used single equation, partial adjustment models with the price specified as the contract rate. In this study, two of the assumptions that underlie these previous studies are tested empirically. First, the proper specification of the price of mortgage funds is tested by using both the contract rate alone and all of the terms of the mortgage as the price. Second, the speed of adjustment in the mortgage market is examined by estimating the model in both the instantaneous adjustment and partial adjustment forms. Both of these tests are carried out using a simultaneous equation rather than a single equation model. The empirical results indicate that the contract rate along with the loan initiation fees, the loan-to-value ratio and the maturity is the better specification of price and that the partial adjustment model performs better than the instantaneous model in the mortgage market.     

U.S. Monetary Policy Surprises and Mortgage Rates

This article examines how the U.S. monetary policy surprises impact the mortgage rates in the nation and across five regions from 1990 to 2008. Regression analysis based on bootstrapping shows that surprises in the target federal funds rate (the target factor) have a significantly positive impact on the 1‐year adjustable‐rate mortgage (ARM) rate within the week of the Federal Open Market Committee announcements and the positive impact lasts up to 1 week after the announcements. Surprises in the future direction of the Federal Reserve monetary policy (the path factor) have significantly positive impacts on both the 1‐year ARM rate and the 30‐year fixed mortgage rates in the first week after the announcement. Furthermore, the responses of mortgage rates are asymmetric and affected by the size of monetary policy surprises, the stage of the business cycle and whether the monetary policy is tightening or loosening. There also exists heterogeneity in the mortgage rate pass‐through process across regions and monetary policy surprises have differential impacts on the regional mortgage rates. The cross‐region variations are mainly correlated with the regional housing market conditions, such as home vacancy and rental vacancy rates.     

Mortgage Credit Availability, Housing Starts and the Integration of Mortgage and Capital Markets: New Evidence Using Linear Feedback

This paper employs linear feedback measures to examine the relationship between housing starts and the availability of mortgage credit. Estimates are obtained using monthly data with samples ending with May 1978 and beginning with June 1978. The results indicate that mortgage credit availability contributed significantly to short-run cycles in housing starts in the earlier sample. Such feedback is considerably smaller, however, in the later sample. The results suggest the housing finance sector has become integrated with the overall capital market as the result of the deregulation of thrift deposit rates and the development of the securitized mortgage market.     

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.     

Reversing the Trend: The Recent Expansion of the Reverse Mortgage Market

Reverse mortgages allow elderly homeowners to tap into their housing wealth without having to sell or move out of their homes. However, very few eligible homeowners used reverse mortgages to achieve consumption smoothing until recently, when the reverse mortgage market in the United States witnessed substantial growth. In this article, I examine 1989–2007 loan‐level reverse mortgage data and conduct three sets of analyses to better understand the demand for reverse mortgages among elderly homeowners. First, I study the ZIP code characteristics correlated with reverse mortgage originations. Second, I show that recent reverse mortgage borrowers are significantly different from earlier borrowers in many respects. Third, I investigate the reasons why the reverse mortgage market experienced substantial growth in the mid‐2000s. Combining the reverse mortgage data with county‐level house price data, I find that higher house prices lead to more reverse mortgage originations. Specifically, the increases in house prices account for about one‐third of the overall growth in the reverse mortgage market from 2003 to 2007.     

Taxes, Points and Rationality in the Mortgage Market

This paper addresses the issue of why discount points exist in the mortgage market. In the process of resolving these questions, a number of insights into the mortgage market are achieved. An important principle is that changes in loan structure due to points, prepayments or other deviations in the typical mortgage have no impact on the competitive rate of return. Thus, the essential role of points is not to raise the effective rate of return nor are they the purchase price a risk-averter desires for an option to prepay. Instead it is taxes that play the critical role.     

A Preliminary Investigation into the Effects of the Federal Override of State Usury Ceilings on the Supply of Mortgage Funds by FSLIC-Insured S&Ls in New York and New Jersey

Examined is the economic theory that restrictive usury ceilings reduce the supply of residential mortgage funds and tighten terms of the mortgage instrument. Studied are the mortgage policies adopted by New York and New Jersey FSLIC-insured S&Ls during periods when there were restrictive usury ceilings and when these usury ceilings were removed. The results clearly confirm the theory that effective elimination of usury ceilings increases the supply of mortgage funds and also liberalizes the terms of the mortgage instrument.

Mortgage Pass-Through Securities: Progress and Prospects

This paper discusses the Housing Commission's perspective and recommendations on mortgage pass-through securities markets, reviews federal policy toward such securities in the wake of the Housing Commission Report , and considers prospects for mortgage securities in the housing finance system of the future. Concerning the outlook, it is concluded that massive "securitization" of housing finance may not be inevitable–contrary to the developing conventional wisdom on this topic–partly because the underlying need for secondary market transactions may not be as strong as commonly expected. Furthermore, the relative importance of pass-through securities as secondary market vehicles may erode if federally related programs are phased down in line with Housing Commission recommendations, even if policies currently being developed within the Administration to improve the functioning of fully private securities markets are implemented.     

Residential Mortgage Markets: Current Developments and Future Prospects

Historical developments as well as current innovations have generated significant changes in the structure and operation of the residential mortgage market. General economic stability, a low inflation rate, growth of savings and loan associations, and strong consumer demand marked the fifteen-year period immediately following World War II. In contrast, the decade of the sixties was characterized by increased competition in the mortgage market, a series of credit crunches, and increased governmental activity. In reaction to these and related developments, current innovations affecting the mortgage market focus on design of new mortgage instruments, improvements in market efficiency, and reform of financial institutions. If history is a guide, it suggests that the residential mortgage market responds flexibly to adverse conditions.     

Financial Literacy,Broker–Borrower Interaction and Mortgage Default

This article examines the relationship between broker–borrower interaction in the origination process and subsequent mortgage performance. I show that face‐to‐face interaction between a mortgage broker and borrower before the loan funds is associated with lower levels of ex post default. The relation between face‐to‐face broker–borrower interaction and mortgage performance holds only for borrowers that have characteristics associated with low levels of financial literacy. Specifically, face‐to‐face interaction is negatively related to default for minorities, borrowers located in areas with low levels of education, low‐income borrowers and borrowers with low FICO scores. My results suggest that face‐to‐face interaction between the mortgage broker and borrower may reduce problems associated with financial illiteracy.     

Pricing Efficiency in the Mortgage Market

Traditionally, the presence of serial correlation has been presumed to indicate an inefficient market for financial assets. As Latham [15] discusses, while the absence of serial correlation implies market efficiency, its mere presence does not imply inefficiency. Rather, market efficiency is a characteristic of security pricing. This study investigates pricing efficiency in the mortgage market. Using mortgage loan quotations for 343 institutions over a 71-week period, the empirical findings show that a wide variety of mortgage contracts are efficiently priced.     

Pricing Private Mortgage Insurance

Issues involved in an evaluation of the price of private mortgage insurance are discussed. Cost considerations are emphasized as long-run equilibrium competitive market prices equal long-run marginal and average cost. An empirical evaluation of current insurance premiums vis-a-vis competitive market norms requires more empirical information on the determinants of foreclosures, especially the links between micro and macro determinants. Option pricing models suggest other data comparisons that also may shed light on an evaluation of insurance premiums.     

住房抵押贷款提前还贷风险管理研究

从现代金融和风险管理角度看,住房抵押贷款提前还贷对商业银行是一种期权性风险,对其收取违约金并非国际惯例,也并不是有效的风险补偿方式。商业银行应适应市场竞争需要,接受风险转嫁并提供风险管理服务,运用风险定价技术在按揭交易价格中对提前还贷风险进行补偿。对于已承担的风险,商业银行应构建抵押贷款提前还贷的数据库,通过表内对;中和市场对冲,推出多样化的住房抵押贷款方式,积极推进住房抵押贷款证券化．从而最终增强银行的盈利来源和核心竞争力。     

Mortgage Refinancing with Asymmetric Information

Information asymmetry exists between the lender and the borrower regarding the holding period of the mortgaged real estate; the lender does not know how long the borrower plans to own the house. This information asymmetry allows the cost of obtaining a mortgage to deviate from its value to the borrower. As a result, the exercise price of the option to refinance becomes the cost to the borrower of obtaining a new mortgage instead of the outstanding balance of the existing mortgage as used in previous models. The option to refinance is a sequential option; after the borrower refinances, a new option is obtained to refinance again in the future. A mortgage refinancing model is developed taking information asymmetry and sequential refinancing into account. The model is used to solve for (1) the value to the borrower of a callable mortgage and (2) the minimum interest rate differential between the contract rate of the existing mortgage and the market interest rate needed to justify refinancing.     

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.     

An Analysis of Market Segmentation in Mortgage Lending Between a Commercial Bank and a Mutual Savings Bank*

This paper is concerned with determining whether commercial banks and mutual savings banks serve separable clienteles in the mortgage market. In order to test the hypothesis, determinants of mortgage lending terms at a major commercial bank and a large mutual savings bank were analyzed. The results indicate that market segmentation does exist. However, some variable signs were other than anticipated. Nevertheless, the significance level of the summary statistic shows that the overall population was separable for the two institutions. Thus, the results of this paper are preliminary. To draw general conclusions, additional data from a larger sample must be obtained.
