Resilient homeownership: how partnership-based finance would have prevented the 2008 US mortgage crisis

Abstract

Purpose

The purpose of this study is to demonstrate that the conventional mortgage system is not appropriate for household finance because it encourages equity extraction and excessive leverage during housing boom and leads to negative equity during a housing bust, a situation that translates into mortgage defaults and foreclosures. Home financing could alternatively be structured as a diminishing partnership preventing the homeowner from ever having negative equity.

Design/methodology/approach

Using Johansen’s cointegration test, the authors provide evidence of a long-run relationship between the delinquency rates, volume of refinancing and the change in house price index (HPI) during the 1994–2019 period. To unravel the short run dynamics between these variables, the authors used a Granger causality test that concludes that the volume of refinancing and the change in the HPI Granger cause default rates.

Findings

The authors provide evidence that under the current conventional mortgage system, excessive refinancing opportunities and equity extraction that are the main factors determining delinquency rates leading to a non-sustainable homeownership.

Practical implications

If mortgages were such that they do not incentivize defaults and foreclosures during a housing downturn, the recovery of the housing market always leads to capital gains. Therefore, disincentivizing refinancing and equity extraction would lead to a more sustainable homeownership.

Social implications

Households would be encouraged to pursue sustainable homeownership through a partnership-based model with long-term wealth accumulation for themselves and their heirs rather than short-term home ownership through the conventional mortgage system, leading to negative equity and defaults when the housing market slumps.

Originality/value

Policymakers ought to rethink the mortgage design by promoting partnership-based finance to protect the equity a household accumulates over a lifetime and thereby enhancing stable and sustainable homeownership.
