Decentralized finance (DeFi) is composed of a variety of heterogeneous sectors that are interconnected through an input-output network of its tokens. We first use a panel data set to empirically document the evolution of the DeFi network across its different sectors. Instead of looking at the...

Decentralized Finance (DeFi) is composed of a variety of heterogeneous sectors that are interconnected through an input-output network of its tokens. We use a panel data set to empricially document the evolution of the DeFi network across its different sectors. We then employ a standard,...

We develop a dynamic model of decentralized finance (DeFi) lending that incorporates two/these key features: 1) borrowing and lending are decentralized, anonymous, overcollateralized and backed by the market value of crypto assets where contract terms are pre-specified and rigid; and 2)...

We develop a dynamic model of DeFi lending that incorporates the following key features: 1) borrowing and lending are decentralized, anonymous, overcollaterlized, and backed by the market value of crypto assets where contract terms are pre-specified and rigid; and 2) information friction exists...

How well can a cryptocurrency serve as a means of payment? We study the optimal design of cryptocurrencies and assess quantitatively how well such currencies can support bilateral trade. The challenge for cryptocurrencies is to overcome double-spending by relying on competition to update the...

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)...

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-vs-payment by linking transfers of assets with payments and operates via a Proof-of-Work protocol. The main benefit of a blockchain is...

We study the trading dynamics in an asset market where the quality of assets is private information of the owner and finding a counterparty takes time. When trading of a financial asset ceases in equilibrium as a response to an adverse shock to asset quality, a large player can resurrect the...

This article provides an analysis of the value proposition of De(centralized) Fi(nance) and its limitations using a simple stylized model of collateralized lending. DeFi uses a decentralized ledger to run smart contracts that automatically enforce the terms of a lending contract and safeguard...
