Benefits to Homeowners from Mortgage Portfolios Retained by Fannie Mae and Freddie Mac

Mortgage investing is the domain of financial intermediaries, such as Fannie Mae and Freddie Mac, who possess specialized knowledge and experienced analytic teams. Capital is channeled to homeowner/borrowers at lower cost through such entities. As the demand for mortgage borrowing outstrips aggregate domestic saving (which is currently negative) foreign sources of capital should become even more significant. Foreign capital can be channeled efficiently into the U.S. mortgage market by Fannie and Freddie. Their debt has the highest credit standing and their risk management ability has been demonstrated by their enormous retained portfolios of mortgages.     

A New Approach to Group Structure, Burden Sharing, and the Equilibrium Provision of Public Goods

In the received model of the voluntary provision of a pure public good, the usual practice is to proceed from assumptions about the group characteristics to inferences about an implied outcome. The approach advocated in this paper reverses the traditional direction. Assuming a Nash equilibrium, we ask how to characterize the diverse set of group characteristics which will support it. Approaching the problem from this angle we define three crucial characteristics of a group-equilibrium: consumer's free rider inducing supply, zero contribution-inducing wealth and voluntary surplus tribute which is the amount by which a person's actual income exceeds his/her zero-contribution inducing wealth. Defining these indicators we show how they form the foundation of a complete mapping between the distribution of individual characteristics of a group, and equilibrium public good supply. Certain questions such as the interaction between size of the group and heterogeneity of incomes and tastes not yet adequately addressed are shown to yield easily to this approach.     

Balance Sheets, the Transfer Problem, and Financial Crises

In a world of high capital mobility, the threat of speculative attack becomes a central issue of macroeconomicpolicy. While first-generation and second-generation models of speculative attacks both have considerablerelevance to particular financial crises of the 1990s, a third-generation model is needed to make sense of thenumber and nature of the emerging market crises of 1997-98. Most of the recent attempts to produce such amodel have argued that the core of the problem lies in the banking system. This paper sketches another candidatefor third-generation crisis modeling—one that emphasizes two facts that have been omitted from formal modelsto date: the role of companies' balance sheets in determining their ability to invest, and that of capital flows inaffecting the real exchange rate.

Commercial Mortgage Default: A Comparison of Logit with Radial Basis Function Networks

This article explores the use of artificial neural networks in the modeling of foreclosure of commercial mortgages. The study employs a large set of individual loan histories previously used in the literature of proportional hazard models on loan default. Radial basis function networks are trained (estimated) using the same input variables as those used in the logistic. The objective is to demonstrate the use of networks in forecasting mortgage default and to compare their performance with that of the logistic benchmark in terms of prediction accuracy. Neural networks are shown to be superior to the logistic in terms of discriminating between good and bad loans. The study performs sensitivity analysis on the average loan and offers suggestions on further improving prediction of defaulting loans.     

Fixed-Rate Endowment Mortgage and Mortgage Indemnity Valuation

We use a contingent claims framework for valuing the the default and prepayment embedded options in certain British fixed-rate endowment mortgages, with a (capped) mortgage indemnity guarantee (MIG). This methodology provides a template for the borrower, lender, and insurer to compare mortgage terms, including the fairness of contract rates, arrangement fees, prepayment penalties, any MIG premiums required, and co-insurance exposure. With empirical inputs, this model may eventually be useful as a mark-to-value proxy for all parties, as expected parameters change (especially interest rate and house price levels, and expected future volatilities), for purposes of determining valued added accounting, appropriate reserves, and indeed for setting premiums and business drivers. Fixed-rate endowment mortgages differ from fixed-rate repayment mortgages primarily because, in the event of early termination, the amount owed by the borrower is a function of the evolution of the term structure of interest rates, whereas for a repayment mortgage it is pre-determined. We compare endownment and repayment mortgages for different levels of loan-to-value ratios, interest rate and house price volatilities.     

Analyst Following and Equity Offerings Subsequent to Initial Public Offerings

Analyst forecast information is collected for firms following their IPOs and is used in an examination of subsequent seasoned equity offerings (SEOs). Consistent with information asymmetry arguments, the analysis indicates that a larger percentage of firms conducting SEOs within three years of the IPO are covered by financial analysts than those without SEOs, and that analyst coverage is a significant predictor of subsequent SEOs. In addition, the results indicate that long-term earnings growth forecasts are larger for firms with subsequent SEOs, but growth forecasts decline significantly following the SEOs. Further, SEO abnormal returns exhibit a significant negative relationship with earnings growth forecasts. These results are consistent with windows of opportunity arguments since they suggest that SEOs are timed to coincide with the peak of earnings growth expectations, but that market participants compensate by reacting more negatively to offerings by firms with high growth forecasts.     

The pricing of FIREARMs (“Falling Interest Rate Adjustable-Rate Mortgages”)

The purpose of this article is to propose and price a new type of adjustable-rate mortgage: the FIREARM (Falling Interest Rate Adjustable-Rate Mortgage). The interest payments on this mortgage adjust downward whenever interest rates decline, while remaining stable when interest rates increase. The FIREARM is alternatively priced as a prepayable and non-prepayable mortgage with a spread over the short-term interest rate. We price these two instruments and contrast their prices with those of fixed-rate mortgages using the parsimonious assumptions of a non-stationary arbitrage-free binomial term structure model.     

Company Tax Structure and Company Tax Incidence

This paper reviews conflicting theories of company tax incidence impliedby the alternative new and traditional views of dividends andexamines their contrasting policy implications. Whereas, under thetraditional view, closer integration of the corporate and personalincome tax systems is suggested, an alternative policy orientationemphasizing the non-distorting features of the classical system is impliedby the new view. Even if the traditional view is accepted, theimplications for design and reform of the company tax vary widely underalternative specifications of domestic and international tax policy objectives. Schedular alternatives to global income taxation are alsoconsidered.     

Interest-only and principal-only mortgage strips as interest-rate contingent claims

Interest-only (IO) and principal-only (PO) mortgage strips are valued in a stochastic interest-rate environment. The prepayment rate of the underlying mortgages is affected by two considerations not present in the pure financially rational model: (1) The property owner's holding period is assumed to follow a Gamma distribution, resulting in the possibility of prepayment due to the sale of the property (i.e., prepayment that is too early based on market interest rates); and (2) borrowers are assumed to face heterogeneous transaction costs related to refinancing the existing mortgage, and delay refinancing when market conditions make it optimal to do so (refinancing too late). Properties of IO/PO strips are identified by the finite difference method.     

Strategic default,workout, and commercial mortgage valuation

This paper extends existing equilibrium commercial mortgage pricing models by endogenizing negotiated workout into the usual noncooperative lending game. Workout is a feasible subgame strategy for the lender to play whenever foreclosure transaction costs exist for either party to a loan transaction. In particular, negotiated workout solutions Pareto dominate the foreclosure alternative when default occurs. To obtain our results, we embed a cooperative bargaining game within a noncooperative mortgage loan/default game. We also address the valuation wedge problem that occurs when foreclosure transaction costs are introduced. Through the notion of replacement game equilibrium, we find symmetric mortgage pricing solutions that eliminate the valuation wedge and thus suggest that lending will occur in commercial real estate mortgage markets even when foreclosure transaction costs exist.     

Explaining intercity home price differences

This paper develops and tests an equilibrium model seeking to explain intercity variation in owner-occupied housing prices. Empirical tests with a reduced form equation using aggregated 1980 data on 94 SMSAs suggest explanation for 84% of this intercity home price variation. Intercity housing demand, based upon homeowner quality of life equilibrium, is successfully represented by the non-monetary income determinant of climate mildness in addition to several monetary income determinants that reflect household residual after-tax real income. Intercity housing supply was found to be influenced by intercity variation in construction costs and limitations upon the available supply of undeveloped urban land.     

Do Market Makers Suffer from Splitting Headaches?

Studies of transactions surrounding stock split ex-dates often conclude that splitting firms either experience a decline or an improvement in their stock's liquidity, based on independent measures of trading costs and trading activity. In contrast, our evidence suggests that splits from outside into what often is deemed to be the optimal stock price range of $10.00 to $39.99 are nonevents for market makers: The spread-setting behavior of the market does not change after a split. Our analysis accounts for the interdependencies between bid-ask spreads and market microstructure effects and distinguishes between optimal and all other splitting firms.     

The Information Content of Bank Examinations

We identify three types of information from bank examinations—auditing information from verifying the honesty and accuracy of the bank's books, regulatory discipline information about the treatment of the bank by regulators, and private information about bank condition. We estimate these information effects by comparing the cumulative abnormal market returns associated with examinations in which the CAMEL rating remained unchanged, improved, and worsened. All three information effects are found to be greater for banks entering the examination process with unsatisfactory ratings from prior examinations. The only consistently strong effect found is that examination downgrades appear to reveal unfavorable private information about bank condition. The evidence also suggests that the information may reach the market in part through loan quality data released in quarterly financial statements.     

The “Rent-To-Own” mortgage and prepayment risk

The most important risk factor in the mortgage and mortgage-backed security market has been prepayment risk. Various innovations have arisen to deal with it but none hedge it fully. The Rent-To-Own (RTO) mortgage discussed here is a mortgage instrument that reduces or even reverses prepayment risk. It does so by creating an incentive structure within the framework of the mortgage contract that penalizes prepayment when interest rates are low and rewards it when interest rates are high. This is the opposite of standard mortgages. The RTO incentive structure is based on a unique buyout feature. Borrowers who want to buy out the financial interest of the lender may do so whenever they want, but the buyout price is a negative function of the market interest rates prevailing currently, that is, at the time of the buyout. Hence the lower these rates, the higher the buyout price. Other advantages of the RTO mortgage are also described.     

On Transitory Earnings

The paper develops a concept of transitory earnings and contrasts this source of earnings to core (or recurring) earnings. It is shown that any two of the following three attributes of transitory earnings imply the third: (i) forecasting irrelevance with respect to next-period aggregate earnings, (ii) value irrelevance, and (iii) unpredictability. The paper makes the case that the current dirty surplus items make sense, especially if one expands the valuation perspective to also allow for agency considerations.     

On the Economics of Subprime Lending

US mortgage markets have evolved radically in recent years. An important part of the change has been the rise of the subprime market, characterized by loans with high default rates, dominance by specialized subprime lenders rather than full-service lenders, and little coverage by the secondary mortgage market. In this paper, we examine these and other stylized facts with standard tools used by financial economists to describe market structure in other contexts. We use three models to examine market structure: an option-based approach to mortgage pricing in which we argue that subprime options are different from prime options, causing different contracts and prices; and two models based on asymmetric information–one with asymmetry between borrowers and lenders, and one with the asymmetry between lenders and the secondary market. In both of the asymmetric-information models, investors set up incentives for borrowers or loan sellers to reveal information, primarily through costs of rejection.     

The impact of tax on foreign direct investment: Empirical evidence and the implications for tax integration schemes

We estimate the impact of taxation on foreign direct investment (FDI) flows, using data on flows between seven countries for 1984 through 1989, and a sophisticated measure of the cost of capital. We find that the choice between domestic investment and total outward FDI is not significantly affected by taxation but that taxation does affect the location of outward FDI. These results are used to examine the impact of tax integration systems. Giving a tax credit to foreign shareholders may induce a large increase in inward FDI from exemption countries but not from partial-credit countries. For the United States, the total effect would be small.     

Performance of residential mortgages in low and moderate-income neighborhoods

This paper presents the first data on performance of mortgages on residences located in lowand moderate-income neighborhoods of U.S. cities. It provides new data on delinquencies and foreclosure provided by a sample of lenders who are members of the National Association of Affordable Housing Lenders and who have lending programs established pursuant to the Community Reinvestment Act.Sample mortgages on multifamily dwellings perform comparably with national sample data, whereas sample mortgages on single-family mortgages perform much better than comparable national sample data.The findings of this paper demonstrate clearly that lending programs in lowand moderate-income neighborhoods can be viable. The findings do not, however, help to settle the issue as the racial or gender discrimination in mortgage origination.This paper is based on Performance Analysis of Community Reinvestment Programs, prepared by the athors for the Woodstock Institute, Chicago, IL.     

The Effect of Mortgage Price and Default Risk on Mortgage Spreads

Variations over time in mortgage yield spreads should reflect changes in the underlying prepayment option value; moreover, the relationship between mortgage yield spreads and interest rate dynamics should weaken as the value of the borrowers prepayment option declines. We verify this hypothesis through an empirical analysis of residential mortgage yield spread behavior, and we also present evidence that the strength of the relationship between mortgage spreads and interest rate dynamics weakens (strengthens) as the level of default risk increases (decreases). This result is consistent with the competing risks effect between a borrowers option to prepay or default. Our results demonstrate the importance of accounting for mortgage price discount to par as well as default risk when developing time series of mortgage yields.
