Economics of Permissioned Blockchain Adoption
构建经济框架分析供应链中许可型区块链的采用激励，发现区块链能减少信息不对称、提升消费者福利，但制造商因竞争无法转嫁成本，导致均衡中不会自发采用，并提出了促进社会最优采用的转移支付方案。
We construct an economic framework for understanding the incentives of the participants of a permissioned blockchain for supply chains and other related industries. Our study aims to determine whether adoption of blockchain is socially beneficial and whether such adoption arises in equilibrium. We find that blockchain reduces information asymmetry for consumers, thereby enhancing consumer welfare. Consumer welfare gains can be sufficiently large that blockchain adoption is socially beneficial; nonetheless, we find that blockchain adoption does not arise in equilibrium. This situation arises because blockchain adoption costs are borne by manufacturers, and manufacturers cannot extract consumer gains through prices due to the competitive nature of the manufacturing sector. We offer a system of transfers to generate blockchain adoption in equilibrium when it is socially beneficial. This paper was accepted by Vishal Gaur, operations management.
