A computational model of the effects of borrower default on the stability of P2P lending platforms
Peer-to-peer (P2P) lending has attracted scholarly attention because of its economic significance and potential to democratize access to finance. However, P2P lending platforms face many challenges and failures that we need to understand more clearly. We build a computational model to study how borrower default affects P2P platform lending. We show that borrower default disrupts the P2P network formation process and undermines platform stability. Moreover, we find that defaults increase the inequality in accessing funding and provide a rationale for using curation rules, widely used in P2P platforms, in contrast to P2P insurance, which fosters cascading defaults. We also address a new trend in P2P lending platforms in which large companies (institutional investors) play an increasingly important role. We find that the presence of large companies creates a denser network (more loans) but generates a trade-off between making the platform more resilient to cascading defaults and more dependent on specific players. Overall, we explain how borrower defaults affect platform stability and what makes a platform vulnerable, threatening its survival. We discuss research and managerial insights into platform stability and the economic effect of P2P lending platforms.
期刊介绍:
The mission of Eurasian Economic Review is to publish peer-reviewed empirical research papers that test, extend, or build theory and contribute to practice. All empirical methods - including, but not limited to, qualitative, quantitative, field, laboratory, and any combination of methods - are welcome. Empirical, theoretical and methodological articles from all fields of finance and applied macroeconomics are featured in the journal. Theoretical and/or review articles that integrate existing bodies of research and that provide new insights into the field are highly encouraged. The journal has a broad scope, addressing such issues as: financial systems and regulation, corporate and start-up finance, macro and sustainable finance, finance and innovation, consumer finance, public policies on financial markets within local, regional, national and international contexts, money and banking, and the interface of labor and financial economics. The macroeconomics coverage includes topics from monetary economics, labor economics, international economics and development economics.
Eurasian Economic Review is published quarterly. To be published in Eurasian Economic Review, a manuscript must make strong empirical and/or theoretical contributions and highlight the significance of those contributions to our field. Consequently, preference is given to submissions that test, extend, or build strong theoretical frameworks while empirically examining issues with high importance for theory and practice. Eurasian Economic Review is not tied to any national context. Although it focuses on Europe and Asia, all papers from related fields on any region or country are highly encouraged. Single country studies, cross-country or regional studies can be submitted.
