The Subprime Mortgage Calamity and the African American Woman

Many media and scholarly reports have focused on the subprime mortgage crisis and the resultant global financial meltdown. Most of the literature notes unequivocally that discrimination in the mortgage market has been, and remains, race-based and that it has damaged the African-American population disproportionately. This paper discusses the consequences of the subprime mortgage calamity and its negative impact on the Black community, women in general, and African-American women in particular. After controlling for individual, credit and housing characteristics, research shows that disparities in lending have persisted. Studies indicate that 63% of those given subprime mortgages qualified for prime mortgages. African-American females received the most high-cost loans and were over twice as likely to be given a subprime mortgage compared to White females. Moreover, African-American women were five times more likely to have received a subprime loan than similarly situated White males. Upper-income Black women were more often targeted for high-cost loans than lower-income women of color. As a result, the subprime mortgage crisis has precipitated an enormous loss of home equity and wealth among African-Americans that will affect generations to come.     

Diagnosing housing fever with an econometric thermometer

Housing fever is a popular term to describe an overheated housing market or housing price bubble. Like other financial asset bubbles, housing fever can inflict harm on the real economy, as indeed the U.S. housing bubble did in the period following 2006 leading up to the general financial crisis and great recession. One contribution that econometricians can make to minimize the harm created by a housing bubble is to provide a quantitative “thermometer” for diagnosing ongoing housing fever. Early diagnosis can enable prompt and effective policy action that reduces long-term damage to the real economy. This paper provides a selective review of the relevant literature on econometric methods for identifying housing bubbles together with some new methods of research and an empirical application. We first present a technical definition of a housing bubble that facilitates empirical work and discuss significant difficulties encountered in practical work and the solutions that have been proposed in the past literature. A major challenge in all econometric identification procedures is to assess prices in relation to fundamentals, which requires measurement of fundamentals. One solution to address this challenge is to estimate the fundamental component from an underlying structural relationship involving measurable variables. A second aim of the paper is to improve the estimation accuracy of fundamentals by means of an easy-to-implement reduced-form approach. Since many of the relevant variables that determine fundamentals are nonstationary and interdependent we use the endogenous instrumental variable based method (IVX) to estimate the reduced-form model to reduce the finite sample bias which arises from highly persistent regressors and endogeneity. The recursive evolving test proposed by Phillips, Shi, and Yu (PSY) is applied to the estimated nonfundamental component for the identification of speculative bubbles. The new bubble test developed here is referred to as PSY-IVX. An empirical application to the eight Australian capital city housing markets over the period 1999–2017 shows that bubble testing results are sensitive to different ways of controlling for fundamentals and highlights the importance of accurate estimation of these housing market fundamentals.     

Housing Fever in Australia 2020–23: Insights from an Econometric Thermometer

Australian housing markets experienced widespread and, in some cases, extraordinary growth in prices between 2020 and 2023. Using recently developed methodology that accounts for fundamental economic drivers, we assess the existence and degree of speculative behaviour, as well as the timing of exuberance and downturns in these markets. Our findings indicate that speculative behaviour was indeed present in six of the eight capital cities at some time over the period studied. The sequence of events in this nation-wide housing bubble began in the Brisbane market and concluded in Melbourne, Canberra, and Hobart following the interest rate rise implemented by the Reserve Bank of Australia in May 2022. As of March 2023, the housing markets in Sydney, Canberra and Hobart had broadly regained stability, while Melbourne's return to its normal state is more gradual. In addition, over-corrections against fundamentals are evident in the housing markets of Brisbane, Adelaide, Darwin and Perth.
