Principal Researcher

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.

Curriculum vitae


Central Bank Digital Currency and Banking

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.

Competing Currencies in the Laboratory

Staff Working Paper 2017-53 Janet Hua Jiang, Cathy Zhang
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.

Adoption of a New Payment Method: Theory and Experimental Evidence

Staff Working Paper 2017-28 Jasmina Arifovic, John Duffy, Janet Hua Jiang
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.

Understanding the Cash Demand Puzzle

Staff Working Paper 2014-22 Janet Hua Jiang, Enchuan Shao
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.

Interest on Cash, Fundamental Value Process and Bubble Formation on Experimental Asset Markets

Staff Working Paper 2014-18 Giovanni Giusti, Janet Hua Jiang, Yiping Xu
We study the formation of price bubbles on experimental asset markets where cash earns interest. There are two main conclusions.
