We build models with an interest-bearing central bank digital currency (CBDC) to investigate whether the interest-bearing CBDC can lead to financial disintermediation. Our model of CBDC and banking captures a key feature of an intermediated CBDC system that idle CBDC can be converted into...

The authors study banking using the tools of mechanism design, without a priori assumptions about what banks are, who they are, or what they do. Given preferences, technologies, and certain frictions - including limited commitment and imperfect monitoring - they describe the set of incentive...

Are financial intermediaries—in particular, banks—inherently unstable or fragile, and if so, why? We address this question theoretically by analyzing whether model economies with financial intermediation are more prone than those without it to multiple, cyclic, or stochastic equilibria. We...
