Environmental Hazards and Mortgage Credit Risk: Evidence from Texas Pipeline Incidents

Minhong Xu, Yilan Xu

Research output: Contribution to journalArticlepeer-review


This study examines the effects of pipeline hazards on credit risk using evidence from the 2005–2011 home mortgage loans in Texas. Difference-in-difference analyses show a permanently lower origination rate by 1.9% in the pipeline-present areas compared to the pipeline-free areas, which was further enlarged by 1.8% whenever pipeline incidents happened. Evidence suggests that the permanent difference in credit access reflects lenders’ concerns about collateral value and borrowers’ repayment ability. The elevated post-incident risk perceptions indicate lenders’ aversion to environmental liabilities. Lenders’ risk management strategies differed by borrowers’ income and evolved with the tightening of the securitization market.
