New (!) & Ongoing Work
Randomized Entry: The Equilibrium Effects of Entry in Digital Financial Markets [v: February 2025 (PDF)] [v: NBER Working Paper (PDF)], AEA RCT REGISTRY (with MTN MobileMoney Ltd and Ghana Commercial Bank Ltd)
[enlisting non-financial firms to provide retail financial services is a widespread and scalable practice globally. yet, little is known about the equilibrium effects of such market entry approach on firms and consumers, and on markets. we created randomized variation across and within markets to estimate the direct, indirect, and multiplier effects of small microenterprises’ entry into a new market: the market for mobile money services.]
Beliefs Over Contracts, AEA RCT REGISTRY (with MTN MobileMoney Ltd and Collin Raymond)
[why do firms choose different incentive contracts? what contracts do firms/managers believe to work best and why? what contracts work best in practice? how well do managers' predictions align with actual outcomes? what leads managers to be able to better predict which contracts will work well?]
