Safe Payments

Staff Working Paper 2020-53 Jonathan Chiu, Mohammad Davoodalhosseini, Janet Hua Jiang, Yu Zhu
In a cashless economy, would the private sector invest in the optimal level of safety in a deposit-based payment system? In general, because of externalities, the answer is no. While the private sector could over- or under-invest in safety, the government can use taxes or subsidies to correct private incentives.

Bank Market Power and Central Bank Digital Currency: Theory and Quantitative Assessment

Staff Working Paper 2019-20 Jonathan Chiu, Mohammad Davoodalhosseini, Janet Hua Jiang, Yu Zhu
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.

Do Sunspots Matter? Evidence from an Experimental Study of Bank Runs

Staff Working Paper 2014-12 Jasmina Arifovic, Janet Hua Jiang
A "sunspot" is a variable that has no direct impact on the economy’s fundamental condition, such as preferences, endowments or technologies, but may nonetheless affect economic outcomes through the expectations channel as a coordination device. This paper investigates how people react to sunspots in the context of a bank-run game in a controlled laboratory environment.

Money and Price Posting under Private Information

Staff Working Paper 2011-22 Mei Dong, Janet Hua Jiang
We study price posting with undirected search in a search-theoretic monetary model with divisible money and divisible goods. Ex ante homogeneous buyers experience match specific preference shocks in bilateral trades. The shocks follow a continuous distribution and the realization of the shocks is private information.
