Central Bank Digital Currencies and Banking: Literature Review and New Questions

Staff Discussion Paper 2023-4 James Chapman, Jonathan Chiu, Mohammad Davoodalhosseini, Janet Hua Jiang, Francisco Rivadeneyra, Yu Zhu
We review the nascent but fast-growing literature on central bank digital currencies (CBDCs), focusing on their potential impacts on private banks. We evaluate these impacts in three areas of traditional banking: payments, lending and liquidity and maturity transformation. We also take a broader look at CBDCs and highlight two promising directions for future research.

How Do Households Respond to Expected Inflation? An Investigation of Transmission Mechanisms

Staff Working Paper 2024-44 Janet Hua Jiang, Rupal Kamdar, Kelin Lu, Daniela Puzzello
We conduct surveys to study how consumer spending responds to higher inflation expectations. Most respondents spend the same, sticking to fixed budget plans or not considering inflation for spending decisions. About 20% decrease spending because they feel poorer and cut spending to invest in inflation-proof assets. Very few increase spending.

Inflation, Output, and Welfare in the Laboratory

Staff Working Paper 2023-11 Janet Hua Jiang, Daniela Puzzello, Cathy Zhang
We investigate the effect of inflation on output and welfare in the laboratory. Consistent with monetary theory, we find that inflation acts as a tax on monetary exchange and reduces output and welfare.

How Long is Forever in the Laboratory? Three Implementations of an Infinite-Horizon Monetary Economy

Staff Working Paper 2021-16 Janet Hua Jiang, Daniela Puzzello, Cathy Zhang
Standard monetary models adopt an infinite horizon with discounting. Testing these models in the lab requires implementing this horizon within a limited time frame. We compare three approaches to such an implementation and discuss their relative advantages.

Monetary Policy Pass-Through with Central Bank Digital Currency

Staff Working Paper 2021-10 Janet Hua Jiang, Yu Zhu
Many central banks are considering issuing a central bank digital currency (CBDC). This would introduce a new policy tool—interest on CBDC. We investigate how this new tool would interact with traditional monetary policy tools, such as the interest on central bank reserves.

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
We show that issuing a deposit-like central bank digital currency (CBDC) with a proper interest rate would encourage banks to pay higher interest to keep their customers. Banks would then attract more deposits and offer more loans. Hence, a CBDC would not necessarily crowd out private banking.

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.
