Institutional disparities in the pricing of adjustable rate mortgage loans

In recent years, commercial banks and savings and loan associations in South Florida have consistently offered initial adjustment period teasers, or subsidies, on their adjustable rate mortgage loans (ARMs). This study adopts the size of the initial subsidy as a proxy for a lender's willingness to offer ARM loans and develops an econometric model which relates the size of the teaser to a series of internal variables (other lending parameters), and external variables (financial market conditions).The results suggest that subsidization policies are not identical across institutions. Specifically, savings and loan associations seem to be less willing than commercial banks to accept the interest rate exposure inherent in ARM lending when future loan rates are constrained by adjustment limits. Consequently, the study argues that the character of a lender's existing assets influences its reactions to the risk/return properties of new assets.This paper has benefitted greatly from the comments of the Journal's reviewers. Responsibility for remaining errors rests with the author.     

Teaser rates in conventional adjustable-rate mortgage (ARM) markets

This article examines the pricing of teaser rates on adjustable-rate mortgages (ARMs). The theory indicates that lenders may offset teaser rates on ARMs through an increase in upfront fees or points, through looser life of loan rate caps, or through higher contract rates after the teaser has expired. Cross-sectional regression results fail to reject the null hypothesis that teaser ARMs are correctly priced.     

The pricing of exchange rate risk and stock market segmentation: The Canadian case

Empirical evidence by Eun and Resnick (1988), among others, has demonstrated the significance of exchange rate risk in the international asset allocation and they have noted that the risk is nondiversifiable. Yet, exchange rate risk was found by Jorion (1991) to be a risk factor that is not priced in the U.S. stock market. This study reexamines such counterintuitive results using data from the Toronto Stock Exchange. The evidence here weakly supports the pricing of the exchange rate risk. Further, the sample period in this study coincides with Jorion's to ensure that both studies examine the pricing of the exchange rate risk in the same global economic environment. The significant pricing of exchange rate risk in Canada and the insignificant pricing in the U.S. imply the possibility of market segmentation.     

The impact of exchange rate risk on international asset pricing under various market structures

This article derives international equity pricing relations by taking into account inflationary exchange risk under various forms of market segmentation/integration. In a mean-variance framework, a two-country, two-period, two-goods model is analyzed under three different market structures: segmented, mildly segmented and integrated. It is found that as long as investors are consuming imported goods, in the presence of market frictions, inflationary exchange risk is an important determinant of real equity prices. This is the case because inflationary exchange rate affects the real purchasing power of investors.

Analytic bond pricing for short rate dynamics evolving on matrix Lie groups

We provide closed-form expressions for bond prices in interest rate models based on compact Lie groups. Our approach uses a Doob transform technique and PDE solutions by the Mathieu periodic functions. As a by-product, we derive formulas for bond option prices as well as new identities for the Laplace transform of periodic functionals of Brownian motion and Brownian diffusion processes.     

Interest rate indexation and the pricing of loan commitment contracts

The central question addressed in this paper is why most loan pricing agreements between banks and their commercial customers involve additive rather than multiplicative markups over the base lending rate. It is argued that banks generally prefer additive pricing because the real value of the premiums moves inversely with inflation. Therefore this pricing formula provides an automatic partial inflation hedge for banks. Most borrowers who hold long positions in nominal assets also prefer this formula for the same reason. However, some borrowers who hold net short positions in nominal assets prefer multiplicative pricing. Banks provide them with such a form of pricing in exchange for appropriate compensation. Supporting empirical evidence is provided.     

Bond and option pricing for interest rate model with clustering effects

This paper analyzes an interest rate model with self-exciting jumps, in which a jump in the interest rate model increases the intensity of jumps in the same model. This self-exciting property leads to clustering effects in the interest rate model. We obtain a closed-form expression for the conditional moment-generating function when the model coefficients have affine structures. Based on the Girsanov-type measure transformation for general jump-diffusion processes, we derive the evolution of the interest rate under the equivalent martingale measure and an explicit expression of the zero-coupon bond pricing formula. Furthermore, we give a pricing formula for the European call option written on zero-coupon bonds. Finally, we provide an interpretation for the clustering effects in the interest rate model within a simple framework of general equilibrium. Indeed, we construct an interest rate model, the equilibrium state of which coincides with the interest rate model with clustering effects proposed in this paper.

The closing rate on residential mortgage commitments: An econometric analysis

Mortgage lenders routinely guarantee rates and points for periods of 60 days or more and hedge the inherent interest rate risk by selling the proportion of mortgages expected to close in forward markets. This article presents a model of the decision to close on the mortgage and demonstrates that the estimates of the model increase the precision of closing rate forecasts. The analysis indicates that changes in mortgage rates are important determinants of the closing rate for fixed-rate mortgages (FRM) and adjustable-rate mortgages (ARM). Other important factors include whether the mortgage is for a new purchase, for owner occupancy, and for a single-family house, and what the overall level of mortgage rates and the loan-to-value ratio are and whether the rate guarantee was granted at the application date or later.     

Contract theory and mortgage foreclosure moratoria

Contracts are an essential institution in capitalist economies. Contract law provides a long and interesting constitutional history. At the same time, mortgage foreclosure moratoria is shown to be an occasional and repeated phenomenon. This paper explores the legal and economic aspects of this issue via a survey of the schools of thought on contracts. The paper also speculates about the nature of mortgage contracts and the economics of moratoria statutes.     

Optimal mortgage contracts with time-inconsistent preferences

This paper integrates a time-inconsistent preference into the mortgage design problem and studies the corresponding effects on the optimal contract. By assuming exogenous time inconsistency in borrower's preference, we find that the time-inconsistent preference increases the loss in the lender's value and the compensation boundary. We implement the optimal contract using standard securities and option adjustable-rate mortgages (ARMs). The findings show that the time-inconsistent preference increases the default rate, and relative to standard securities, option ARMs increase the total debt capacity, but the borrower's time inconsistency can lead to sudden jumps in the total debt capacity. We also consider the endogenous time inconsistency in the borrower's preference and derive the corresponding mortgage contract; we find that a lender can perfectly offset the effect of a borrower's time inconsistency on the value function and compensation strategy. The liquidation boundary at the low interest rate varies with the degree of time inconsistency, explaining the heterogeneity in mortgage default behaviors observed in practice.     

The use of digital footprints in the US mortgage market

We study the rise of digital footprint (DF) users in the U.S. residential mortgage market. The proportion of lenders that use a borrower's DF has witnessed remarkable growth from 6% in 2013 to 34% in 2018 in a short span – according to our analysis. We show that the use of DFs can significantly reduce a lender's overall risk and that the use of DFs can result in considerable societal benefits, by reducing the overall discriminatory forces. In sum, we provide evidence that the informational advantage associated with using a borrower's DF far outweighs that of existing traditional lending methods.     

Housing and the mortgage securities markets: Review,outlook, and policy recommendations

During the 1980s, strong demographic demand for housing created a bulging need for mortgage credit. The mortgage market has creatively accommodated this need through extensive securitization of residential mortgages. This process greatly facilitated the financing of housing demand. During this decade, however, the scheme of funding long-term mortgages with short-term deposits bankrupted savings institutions. A gigantic federal bailout for thrifts was finally required. In the 1990s, the weakening demographics and the resulting reduction in the demand for mortgage credit afford the federal government opportunities to reformulate its housing policies in terms of limiting federal insurance on consumer deposits, phasing out income tax deductibility of mortgage interest, and ensuring capital adequacy at federally sponsored credit agencies.

Production-based measures of risk for asset pricing

A stochastic discount factor for asset returns is recovered from equilibrium marginal rates of transformation inferred from producers’ first-order conditions. The marginal rate of transformation implies a novel macro-factor asset pricing model that does a reasonable job explaining the cross-sectional variation in average stock returns with plausible parameter values. Using a flexible representation of firms’ production technology, producers’ ability to transform output across states of nature is estimated to be high, in contrast with what is typically assumed in standard aggregate representations of firms’ production technology.     

Determinants of financial covenants and pricing of debt in private debt contracts: the UK evidence

This paper presents details of financial covenants given by a sample drawn from the largest 200 non-financial quoted firms in the UK in private debt contracts and analyses these data to see whether there are relationships between the nature of the covenants given and firm characteristics. Data were obtained from 72 firms, of which 17 gave no financial covenants. Firm size was found to be the only significant factor influencing whether firms did or did not give covenants as well as the only factor which influenced the margin given on debt. Some types of covenants given were found to be different from those found in previous research. In particular, there is greater use of EBITDA as a base for both interest cover and gearing covenants. This shows the importance of cash flow based lending as opposed to asset based lending for general financing for large firms.     

Frictions, Heterogeneity and Optimality in Mortgage Modeling

The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.
