Do digital payment technologies generate liquidity premia like cash and Treasury? We provide an estimate in the context of the world's largest digital payment platform, Alipay. Our empirical strategy exploits the variation in the timing of the introduction of money market funds that users on...

We provide evidence that expansionary fiscal policy lowers the return difference between more and less liquid assets—the liquidity premium. We rationalize this finding in an estimated heterogeneous-agent New-Keynesian (HANK) model with incomplete markets and portfolio choice, in which public...
