This paper studies the economic impact of introducing a personal bankruptcy regime, using China’s recent pilot reforms as a natural experiment. We exploit the staggered rollout of personal bankruptcy frameworks across Chinese cities and construct a novel dataset of bankruptcy case filings, combined with survey-based measures of credit access and official firm registration records. Our difference-in-differences estimates show that the reforms significantly improve small business credit access - business loan take-up increases by 1.3 % (21% relative to pre-reform mean), with no offsetting rise in interest rates. Effects are concentrated among non-corporate firms, firms with less employees and female entrepreneurs. Moreover, the reform is also associated with a 9.7% increase in new firm registrations. To interpret these findings, we develop a simple but novel theoretical model in which personal bankruptcy reduces the downside risk of entrepreneurial failure while preserving creditor recoveries. These findings underscore how debtor protection policies, when designed to reduce enforcement costs without expanding exemption rights, can enhance credit supply and entrepreneurial activity.
