Abstract

Many currencies are backed by redemption promises – including historical gold-backed currencies, free bank notes, and emerging stablecoins – but little evidence or theory informs currency redemption policy. We study the impact of redemption policy on steady-state currency acceptance and flows using unique transaction data from a digital platform. We leverage both cross-sectional variation in redemption convenience and unexpected changes in redeemability. We show in a search-theoretic framework that redeemability may induce currency adoption at zero steady-state cost. However, the evidence is more consistent with a heterogeneous –agent model in which redeemability is both costly and necessary for money circulation. An implication is that optimal policy may  impose some degree of redemption friction.
