In this paper, we argue that the observed difference in the cost of intraday and overnight liquidity is part of an optimal payments system design. In our environment, the interest charged on overnight liquidity affects output, while the cost of intraday liquidity only affects the distribution of...

We study the incentives of participants in a real-time gross settlement system with and without the addition of a liquidity-saving mechanism (queue). Participants in our model face a liquidity shock and different costs for delaying payments. They trade off the cost of delaying a payment against...

In this paper I ask whether a central bank policy of providing liquidity to banks during panics can prevent bank runs without causing moral hazard. This kind of policy has been widely advocated, most notably by Bagehot (1873). To analyze such a policy, I build a model with three key features: 1)...

We develop a model in which financial intermediaries hold liquidity to protect themselves from shocks. Depending on parameter values, banks may choose to hold too much or too little liquidity on aggregate compared with the socially optimal amount. The model endogenously generates a situation of...

This paper studies banks' incentives regarding the timing of payment submissions in a collateral-based RTGS payment system and how these incentives change with the introduction of a liquidity-saving mechanism (LSM). We show that an LSM allows banks to economise on collateral while also providing...
