We model aggregate delinquency behaviour for consumer credit (including credit card loans and other consumer loans) and for residential real estate loans using data up until 2008.

Personal credit scoring on credit cards has been a critical issue in the banking industry. The bank with the most accurate estimation of its customer credit quality will be the most profitable.

The predicting models used are instant-based cl...

We provide the first economic research on `buy now, pay later' (BNPL): an unregulated FinTech credit product enabling consumers to defer payments interest-free into instalments. In 2021 transactions by BNPL firms are charged $19.5\%$ of active cards in our UK data. Charging a $0\%$ interest, amortizing debt cards, where typical interest rates $20\%$ and amortization schedules decades-long, rais...
