Abstract

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, theoretical production-network model to measure the value added and service outputs of different DeFi sectors which is fundamentally different from the commonly used metric of Total Value Locked (TVL). Our calibrated model is then used to study DeFi token prices and to predict the equilibrium effects of increasing network interconnectedness.
