The Role of Asset Structure, Ownership Structure, and Takeover Defenses in Determining Acquisition Likelihood

This paper extends the Palepu (1986) acquisition likelihood model by incorporating measures of insider and institutional shareholdings, by examining the deterrent effect of various takeover defenses, and by considering the effect of varying proportions of fixed (tangible) assets in a firms total asset structure. We find that the probability of receiving a takeover bid is positively related to tangible assets, and negatively related to firm size and to the net change in institutional holdings. Blank-check preferred stock authorizations are the only common takeover defense significantly (negatively) correlated with acquisition likelihood.

Modeling the Conditional Probability of Foreclosure in the Context of Single-Family Mortgage Default Resolutions

Both empirical and pricing-simulation models of mortgage default focus on foreclosure in a one-step decision framework. Such models are misspecified to the extent that mortgage default and foreclosure are two separate decisions or events, where foreclosure is but one outcome of a default episode. This study examines the dynamics of mortgage borrower default episodes using a large sample of FHA-insured single-family mortgages. We estimate the influence of borrower characteristics, mortgage terms, and economic conditions on probabilities of various resolutions, highlighting under what conditions foreclosure is more likely to result from mortgage default.

The Fractal Structure of Real Estate Investment Trust Returns: The Search for Evidence of Market Segmentation and Nonlinear Dependency

This article presents a further test for market segmentation between the real estate market and the capital markets. We use rescaled range analysis developed in the fractal geometry literature to test for nonlinear trends in the returns series for different asset classes. We make three major conclusions: (1) the stock market displays tendencies consistent with a random walk, (2) portfolios of mortgage and equity REIT returns display tendencies consistent with a random walk and, (3) conditional upon the methods used, segmentation does not exist between different real estate markets and between the real estate and stock markets.

Cost-Benefit Analysis of Single-Family Foreclosure Alternatives

Over the last ten years, single-family mortgage lenders have become more aware of the financial benefits of finding alternatives to foreclosure for borrowers who default on their mortgage obligations. In this article, expected costs of foreclosure alternatives are parameterized to solve for minimum probabilities of borrower success necessary to make pursuing them profitable for lenders. These break-even probabilities are found to be very insensitive to changes in a variety of factors, including interest-rate environments and time horizons. Simulations are performed across house-price-deflation scenarios, loan-to-value ratios, and post-default cure rates. Stochastic processes are introduced through time distributions for foreclosure processing, property disposition, and house-price appreciation.

Credit Lines and Credit Utilization

While much is known about the characteristics of consumers or businesses that obtain credit lines, relatively little is known empirically about credit line utilization after origination. This study fills that gap by testing two interrelated hypotheses concerning borrower credit quality and credit line utilization. The empirical analysis confirms that borrowers with higher expectations of future credit quality deterioration originate credit lines to preserve financial flexibility. Furthermore, we estimate a competing risks model that confirms our predictions concerning changes in borrower credit line utilization in response to borrower credit quality shocks.

Have the GSE affordable housing goals increased the supply of mortgage credit

Abstract In the 1980s, housing market analysts and policymakers were concerned that Freddie Mac and Fannie Mae were not adequately facilitating the financing of affordable housing for low- and moderate-income families. To address these concerns, the Department of Housing and Urban Development established quantitative Affordable Housing Goals requiring the Government Sponsored Enterprises (GSEs) to increase their purchases of mortgages originated by low- and moderate-income households and for homes located in low-income neighborhoods. Our analysis indicates that the goals increased the supply of mortgage credit available to low- and moderate-income households, after controlling for other mortgage market factors. Our analysis suggests that the increase in the supply of low-income mortgage credit occurred primarily in 1998.

The Hazard Rates of First and Second Defaults

This article examines hazards of repeated mortgage default, conditional on reinstating out of an initial default episode. Results indicate that subsequent default risk for reinstated borrowers is significantly greater than the risk of first default, especially during the first two years after a default episode. In addition, economic factors helpful in predicting first defaults are not helpful in predicting subsequent default episodes. This has important implications for mortgage investors and servicers as industry foreclosure avoidance efforts intensify.

REIT Economies of Scale: Fact or Fiction?

The real estate industry has recently witnessed significant and pervasive consolidation with further growth and consolidation generally viewed as inevitable. For example, between 1990 and 1997, growth in average net real estate investments by large REITs outpaced growth in average net real estate investments by small REITs by 13 percent. However, no systematic study of the benefits of this consolidation exists. This research studies whether or not there are gains to consolidation due to economies of scale from size, brand imaging, and informational gains from geographic specialization. Our sample consists of 41 multifamily equity REITs, for whom financial and property level data are available in the SNL REIT Database. Using this data, we construct shadow portfolios that mimic each REITs exposure to changes in local market conditions. Our results show no size economies, that branding in real estate is allusive, and that geographic specialization, in agreement with Gyourko and Nelling (1996), has no significant benefit.

Comovement after Joining an Index: Spillovers of Nonfundamental Effects

This study considers the case of two overlapping categories in the context of recent category models. Specifically, we examine whether investor sentiment and market frictions specific to one category can affect the returns on assets belonging to the other category. With recent additions of several real estate investment trusts (REITs) into general stock market indices as a natural experiment, we find support for spillovers of such nonfundamental effects, as evidenced by the increased return correlation between REITs that remain outside the index and the index stocks. Further analysis reveals that market frictions play a greater role than investor sentiment.

Optimal Put Exercise: An Empirical Examination of Conditions for Mortgage Foreclosure

Implicit in option-pricing models of mortgage valuation are threshold levels of put-option value that must be crossed to induce borrower default. There has been little research into what these threshold values are that come out of pricing models or how they compare to exercised option values seen in empirical data. This study decomposes boundary conditions for optimal default exercise to look at the economic dynamics that should lead to optimal default timing. Empirical data on FHA insured mortgage foreclosures is then examined to discern the predictive influence of optimal-option-valuation-and-exercise variables on observed default timing and values. Interesting results include a new understanding of how to measure and use property equity variables during economic downturns, house-price index ranges over which default is exercised for various classes of borrowers, and implied differences in appreciation rates between market-price indices and foreclosed properties.
