We investigate the introduction of a central bank digital currency (CBDC) into the market for payments. Focusing on the point of sale, we develop and estimate a structural model of consumer adoption, merchant acceptance and usage decisions. We counterfactually simulate the introduction of a...

The market for payment cards is inherently two sided. Consumers benefit from increased merchant acceptance of payment cards and vice versa. To quantify the interdependence of consumer and merchants or network externalities, we construct and estimate a structural two-sided model of a payment...

Digitalization - the use of data, digital platforms and advanced analytics - has quickly become widespread in today's society. This has introduced new opportunities, but it has also created new barriers and exacerbated existing inequities. This is likewise true in the realm of payments, where...

Research into a hypothetical Digital Canadian Dollar has largely focused on public policy, financial technology innovations and public opinion. In this study, we explore the consumer value proposition of a hypothetical Digital Canadian Dollar, considerations for its adoption and the users who...

The market for payments is an important two-sided one, where consumers benefit from increased merchant acceptance of payment cards and vice versa. The dependence between the decisions that are made on each side of the market results in various network externalities that are often discussed but...

Digital payments and decentralized systems enable the creation of new financial products and services for users. One core challenge in digital payments is the need to protect users from fraud and abuse while retaining privacy in individual transactions. We propose a pseudonymous credential...

A well-functioning monetary system is characterized by public and private forms of money that exchange at par as value flows freely between them. This is essential for efficient transacting and contracting in a market economy. A relevant retail public money - whether in the form of cash, a...

We use a simple model to study whether private payment systems based on bank deposits can provide the optimal level of safety. In the model, bank deposits backed by projects are subject to default risk that can be mitigated by a depositor's ex ante and ex post monitoring. Safe payment...

Digital currencies store balances in anonymous electronic addresses. We analyze the tradeoffs between the safety and convenience of aggregating balances in addresses, electronic wallets and banks. In our model, agents balance the risk of theft of a large account with the cost to safeguarding a...

We frame the wide spectrum of possible system architectures for an online retail central bank digital currency (CBDC) and identify a promising architecture well-suited for basic payments. We select OpenCBDC 2PC, a representative system design that fits this architecture and analyze it using a...
