• Understanding DeFi Through the Lens of a Production-Network Model

  Staff Working Paper 2023-42 Jonathan Chiu, Thorsten Koeppl, Hanna Yu, Shengxing Zhang

  We develop a production-network model to capture how decentralized finance (DeFi) has evolved across different sectors of financial services. The model allows us to measure the value added by different DeFi sectors and to study how the connections across the sectors influence token prices.

• On the Fragility of DeFi Lending

  Staff Working Paper 2023-14 Jonathan Chiu, Emre Ozdenoren, Kathy Yuan, Shengxing Zhang

  We develop a dynamic model to capture key features of decentralized finance lending. We identify a price-liquidity feedback: the market outcome in any given period depends on agents' expectations about lending activities in future periods, with higher future price expectations leading to more lending and higher prices in that period.

• 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.

• Grasping De(centralized) Fi(nance) Through the Lens of Economic Theory

  Staff Working Paper 2022-43 Jonathan Chiu, Charles M. Kahn, Thorsten Koeppl

  We analyze the value proposition and limitations of decentralized finance (DeFi). Based on a distributed ledger and smart contracts, DeFi can guarantee the execution of financial contracts, potentially lowering the costs of intermediation and improving financial inclusion.

• PayTech and the D(ata) N(etwork) A(ctivities) of BigTech Platforms

  Staff Working Paper 2022-35 Jonathan Chiu, Thorsten Koeppl

  Why do BigTech platforms introduce payment services? We explore this using a model in which a monopoly platform faces a trade-off between the costs associated with privacy concerns and the revenue from data services. We then analyze the feedback effects between data and payments.

• Central Bank Digital Currency and Banking: Macroeconomic Benefits of a Cash-Like Design

  Staff Working Paper 2021-63 Jonathan Chiu, Mohammad Davoodalhosseini

  Should a CBDC be more like cash or bank deposits? An interest-bearing, cash-like CBDC not only makes payments more efficient but also increases total demand. This has positive effects on other transactions, inducing more deposit taking and lending and, thus, bank intermediation.

• 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.
