Janet Jiang is a Principal Researcher in the Research Team in the Funds Management and Banking Department. Her current research interests include optimal loss-sharing rules for the large value payment system, the effect of new means of payment on central bank policies, and experimental studies of bank runs, asset bubbles, multiple currencies and competing means of payment. She has also conducted research on how inflation affects banking crises and trading patterns. Janet obtained her PhD in Economics from Simon Fraser University.
Many central banks are considering whether to issue a new form of electronic money that would be accessible to the public. This new form is usually called a central bank digital currency (CBDC). Issuing a CBDC would have implications for the financial system and, more broadly, the wider economy.
We investigate competition between two intrinsically worthless currencies as a result of decentralized interactions between human subjects. We design a laboratory experiment based on a simple two-country, two-currency search model to study factors that affect circulation patterns and equilibrium selection.
We model the introduction of a new payment method, e.g., e-money, that competes with an existing payment method, e.g., cash. The new payment method involves relatively lower per-transaction costs for both buyers and sellers, but sellers must pay a fixed fee to accept the new payment method.
We develop a model to explain a puzzling trend in cash demand in recent years: the value of bank notes in circulation as a percentage of GDP has remained stable despite decreasing cash usage at points of sale owing to competition from alternative means of payment such as credit cards.
