Distributed Ledgers and Secure Multiparty Computation for Financial Reporting and Auditing
研究了分布式账本技术对财务报告和审计的影响，分析了企业误报、审计师监督与竞争、监管政策，发现区块链虽能提高验证效率，但私人激励和先发优势可能导致低效采用，监管协调也可能因企业内生选择交易伙伴而失败。
To understand the disruption and implications of distributed ledger technologies for financial reporting and auditing, we analyze firm misreporting, auditor monitoring and competition, and regulatory policy in a unified model. A federated blockchain for financial reporting and auditing can improve verification efficiency not only for transactions in private databases but also for cross-chain verifications through privacy-preserving computation protocols. Despite the potential benefit of blockchains, private incentives for firms and first-mover advantages for auditors can create inefficient under-adoption or partial adoption that favors larger auditors. Although a regulator can help coordinate the adoption of technology, endogenous choice of transaction partners by firms can still lead to adoption failure. Our model also provides an initial framework for further studies of the costs and implications of the use of distributed ledgers and secure multiparty computation in financial reporting, including the positive spillover to discretionary auditing and who should bear the cost of adoption.
