Another achievement of this research is to elaborate the modified concept of Cash Rebate Mortgages. To examine the difference between Cash Rebate Mortgages and standard mortgages, we have built a simulation model to study the behavior of these two types of mortgages. The results indicate that the value of Cash Rebate Mortgages is higher than that of standard mortgages, but is more sensitive to embedded options. If the probability of exercising an option is higher, then the value of Cash Rebate Mortgages will drop at a faster rate than that of standard mortgages. / Several findings are elaborated in this dissertation. Our model has identified the major contributors to mortgage prepayment, and has developed a logistic regression model to describe prepayment behavior. We further illustrate that prepayment and default behavior are associated with financial reasons: the value of the refinancing incentive is usually greater than the prepayment penalty plus the transaction cost for refinancing mortgages, and the outstanding balance of the mortgage is higher than the current market value of the underlying property minus the transaction cost. / The final objective of this dissertation is to develop an option model for MBS issuers. Most previous studies that have developed MBS models have focused on investors, but the model that is presented here is specifically for MBS issuers. The current study develops a risk management tool for issuers and guarantors to monitor their MBS portfolios. The model projects the cash inflow of mortgages and the cash outflow to MBS, alters the traditional model by introducing decision trees, and uses a simulation program with multiple path generation to develop a model for issuers to manage their MBS portfolios. According to the results of the model, issuers can manage the risk level of their portfolios by determining the Collection Account Balance, the Overcollateralization Ratio, the Net Residual Value, and the Liquidity Advance. Finally this paper also provides suggestions on risk management for MBS issuers. / The objective of this dissertation is to develop an option model for residential mortgages and Mortgage-Backed Securities. Previous studies in the literature have identified several research opportunities that have not yet been explored. The current study attempts to fill the research gap, by altering the traditional model of mortgage valuation with a trinomial tree. We combine the prepayment, delinquency, default, and recovery of delinquency into a single model, to build a simulation program to generate different cash flow scenarios. The industrial data of the Korea Mortgage Corporation and a medium sized Hong Kong bank are used as empirical evidence for the model. / by Yat-ming Lam. / "February 2003." / Source: Dissertation Abstracts International, Volume: 64-09, Section: A, page: 3408. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2003. / Includes bibliographical references (p.

In 2010, regulators established new rules for single-family mortgage services that tightened the loan amount consumers could qualify for, restricted fees lenders could charge, and placed numerous financial penalties for improper servicing of loans. Regulatory fee restrictions made it difficult for leaders to offset the compliance costs through the price of services provided. Leaders responsible for mortgage regulatory compliance experienced increased operating costs for single-family mortgage services due to the new regulations, and some leaders found it challenging to comply and remain competitive. The purpose of this multiple case study was to explore strategies leaders in the single-family mortgage services industry used to comply with federal regulations and remain competitive. The study population included 5 leaders responsible for single-family mortgage regulatory compliance from the southwestern and northern regions of the United States Porter's 5 forces analysis was the conceptual framework. Data were collected using semistructured interviews and analysis of data from a website hosted by government regulators. Data were analyzed using color-coded transcriptions, methodological triangulation, member checking, and coding software. Themes that emerged from data analysis revealed that costs and control methods for regulatory compliance strategies required leaders to change their infrastructure to remain competitive and profitable. The implication of this study for positive social change relates to competitive pricing for single-family mortgage loans for consumers yielding an increase in home ownership.

This dissertation first investigates the possible house price trend and the relationship with the mortgage market, from the perspective of risk management; then it chooses the angle from bond insurers and figures out possible methods to avoid capital procyclicality. In Chapter I, we apply vector auto regression models (VAR) and simultaneous equations models (SEM) to estimate the dynamic relations among house price returns, mortgage rates and mortgage default rates, using historical data during the time period of 1979 through second quarter 2008. We find that house prices would be better estimated and predicted with the consideration of the mortgage market. In Chapter II, following the methodology of co-integration, we first construct several succinct measures to display the possible intrinsic values of house prices. In the short run, house price return dynamics are investigated by dynamic adjustments following Capozza et al (2002) and error correction models. We examine the possible overshooting problem of house price returns. By analytical derivations and simulations, we demonstrate the effects of the coefficients on overshooting. In Chapter III, we adopt a structural model with time-varying correlations for bond insurers. We consider losses due to bond insurers’ downgrading and losses from both insurance contracts and investment portfolio. On that basis, we propose forward-looking smoothing rules of capital over a full business cycle, instead of only based on a short-term horizon, to avoid the procyclicality. With the smoothed capital, a bond insurer can actually establish some capital buffer in good times to support the potential losses in crisis.

The research investigates the application of asset allocation model to pension structure and mortgage payment. The defined contribution pension plan has become the main pension plan in Taiwan. In this pension plan, labors could adjust the contribution rate to maximize their utility function even if they change jobs. Thus, the pension plan may cause changes in their optimal asset allocation. In addition, due to the financial innovations of personalized debt instruments, lenders are allowed to adjust the mortgage payment to maximize personal utility function and hence the adjustable payment ratio could also change the lenders¡¦ optimal asset allocation. This study presents an extended intertemporal asset allocation model of Campbell(1993) and Viceira(2001) to investigate the effects of defined contribution pension and mortgage payment. The numeric simulation is also present to demonstrate the effects on labors¡¦ optimal asset allocation.

This dissertation consists of three independent essays. Chapter 1, "The Effect of Mortgage Securitization on Foreclosure and Modification," assesses the impact of mortgage securitization on foreclosure and modification. My primary innovation is using the freeze of private mortgage securitization in the third quarter of 2007 to instrument for the probability that a loan is securitized. I find that privately securitized mortgages are substantially more likely to be foreclosed and less likely to be modified. Chapter 2, "Disagreement and Liquidity," analyzes how disagreement between investors affects the relationship between trading, liquidity, and asymmetric information. Traditional models predict that asymmetric information should destroy trade and liquidity. In contrast, I document empirical evidence that asymmetric information increases trading volumes in stock, corporate bond, and option markets. To resolve this puzzle, I propose a model of overconfident disagreement trading in which private information enhances trading and liquidity. Chapter 3, "Is Real Interest Rate Risk Priced? Theory and Empirical Evidence," asks whether investors demand compensation for holding assets whose returns covary with real interest rate shocks. Empirically, there is little evidence that real interest rate risk is priced in the cross section of stocks or across asset classes. Theoretically, interest rate risk can be positively or negatively priced depending on whether interest rate changes are due to time preference shocks or consumption growth shocks.
