The number of bankruptcies in Sweden is at its highest level in decades, while reports of financial crime are hitting record levels. Most suspicions of crime are detected and reported by bankruptcy trustees, with auditors as the second most important source. Both groups are legally obliged to act as gatekeepers, protecting creditors and society from financial irregularities. Despite their central role, we know surprisingly little about how effective they are. In this project, we investigate the interaction between bankruptcy trustees and auditors and how audit quality affects the trustee's ability to recover assets, protect creditors and detect crime. With unique access to data on trustee reports, criminal complaints and convictions, we analyze when they succeed, when they fail and why. We also study how professional networks can prevent or enable crime, and how misconduct prediction models can be improved by including information from trustee reports and individual-based risk factors. By bringing together insights from accounting, auditing, law and criminology, the ambition is to generate new knowledge that can be useful in the context of crime prevention. The results are also expected to provide practitioners with better tools to detect financial crime at an early stage. The project combines data on auditors and trustees, crime reports and convictions allowing for unique studies of the role of these gatekeepers in the fight against crime.
