• Requested data using formal legal powers
• Data on payday loans in 2012-3: top 37 lenders, ~99% market
• For 11 lenders, ~90% market, all applications, denied and accepted, including lender credit score and revenues and costs
• Match applicants across firms and to credit bureau files using unique identifier. 6 years of data including loan applications, holding and balances, credit events, defaults and credit bureau credit scores

Recreating lending decisions: credit scores
‘Good’ credit score
45o – credit score has no explanatory power
ROC = Receiver Operating Characteristic

Causal impact of payday loan use on consumersChange in likelihood of
exceeding overdraft limit 95% confidenceinterval • Evidence suggests
payday use worsens financial outcomes
• Use behavioural models to assess welfare impacts
Months relative to first loan application
Next step: identify heterogeneous treatment effects, who is gaining and losing, using data science methods (Athey and Imbens, 2015)

• DATA: FCA collects rich transaction data + legal powers to gather more data
• METHODS: Undertaken rigorous, ground-breaking empirical research to inform policies. Starting to use range of data science methods
• PEOPLE: Empirical economists + data scientists
• OPEN: Open to new ideas for research + collaboration. Regularly work with world-leading academics + aim to publish in top journals
• ACCESSIBLE: Creating high-specification secure cloud environment facilitating off-site access
• REAL-WORLD RELEVANT: Research has to be immediately usable to inform policymakers
