This paper tests for bias in consumer lending decisions using administrative data from a high-cost lender in the United … Kingdom. We motivate our analysis using a simple model of bias in lending, which predicts that profits should be identical for … marginal loan applicants by exploiting variation from the quasi-random assignment of loan examiners. We find significant bias …

This article summarizes our views on the role of an "aggregation bias" in explaining the PPP Puzzle, in response to the … counter-examples which are not empirically relevant; (ii) simulation results minimizing the extent of "aggregation bias"; (iii …) unfounded claims on the impact of measurement errors on our results; and (iv) problematic implementation of small-sample bias …

aggregation bias'. This paper re-examines aggregation bias. First, it clarifies the meaning of aggregation bias and its … applicability to the PPP puzzle. Second, the size of the bias' is shown to be much smaller than the simulations in Imbs et. al …. Finally, it is now standard to recognize that small-sample bias plagues estimates of speeds of convergence of PPP. After …
