• 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.

• 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.

• Blockchain-Based Settlement for Asset Trading

  Staff Working Paper 2018-45 Jonathan Chiu, Thorsten Koeppl

  Can securities be settled on a blockchain and, if so, what are the gains relative to existing settlement systems? We consider a blockchain that ensures delivery versus payment by linking transfers of assets with payments and operates using a proof-of-work protocol. The main benefit of a blockchain is faster and more flexible settlement, whereas the challenge is to avoid settlement fails when participants fork the chain to get rid of trading losses.

• Incentive Compatibility on the Blockchain

  Staff Working Paper 2018-34 Jonathan Chiu, Thorsten Koeppl

  A blockchain is a digital ledger that keeps track of a record of ownership without the need for a designated party to update and enforce changes to the record. The updating of the ledger is done directly by the users of the blockchain and is traditionally governed by a proof-of-work (PoW) protocol.
