In this paper we consider the relative merits of net versus gross settlement of interbank payments. Net settlement economizes on the costs of holding non-interest-bearing reserves, but increases moral hazard problems. The "put option" value of default under net settlement can also distort banks'...

Payment finality is critical to decentralized exchange. By specifying how the transfer of one type of claim extinguishes another, the rules governing finality minimize opportunities for default along credit chains and allocate other risks. ; The authors provide a basic analysis of finality and...

Most people are familiar with retail payments systems such as checks and credit cards. Less familiar are wholesale payments systems, which consist of electronic networks used for sending large sums among banks. A feature common to all wholesale networks is that settlement is carried out by...

The quintessential crime of the information age is identity theft, the malicious use of personal identifying data. In this paper, the authors present a model of identities and their use in credit transactions. The incidence of identity theft represents a tradeoff between a desire to avoid costly...

What are the benefits provided by a payment system? What are the tradeoffs in public versus private payment systems and in restricted versus open payments arrangements? Modern payment systems encompass a variety of institutional designs with varying degrees of counterparty protection. We develop...

Previous comparative analyses of gross and net settlement have focused on the credit risk of the central counterparty in net settlement arrangements and on the incentives for participants to alter the risk of the portfolio under net settlement. By modeling the trading economy that generates the...

We examine the question of whether transactable forms of privately issued, demandable debt are better used as "banknotes" or "checks." The distinction between the two is that a check must be redeemed by the issuing bank with each use, whereas a banknote can circulate. We find that the answer to...

The quintessential crime of the information age is identity theft, the malicious use of personal identifying data. In this paper we model “identity” and its use in credit transactions. Various types of identity theft occur in equilibrium, including “new account fraud,” “existing...

An extensive literature in monetary theory has emphasized the role of money as a record-keeping device. Money assumes this role in situations where using credit would be too costly, and some might argue that this role will diminish as the cost of information, and thus the cost of credit-based...

This paper investigates the question of why banks almost always settle payments in cash as opposed to debt. Our model suggests that adverse selection with respect to the quality of bank assets may be the primary motivation underlying this practice. Banks with higher-quality assets prefer not to...
