Trading Volume Manipulation and Competition Among Centralized Crypto Exchanges
研究了中心化加密货币交易所中竞争如何影响交易量操纵，发现竞争加剧了信息操纵，操纵者短期获利但长期受损。
How competition affects manipulation by firms of information about important attributes of their products and how such information manipulation impacts firms’ short-term and long-term performance are open empirical questions. We use a setting that is especially suitable for answering these questions—centralized crypto exchanges, on which information manipulation takes the form of inflated trading volume. We find that static and dynamic competition measures are positively associated with volume inflation, indicating that competition may lead to increased information manipulation. Exchanges that manipulate volume obtain short-run benefits but are punished in the long run, consistent with the trade-off between short-lived increases in rents and future losses because of damaged reputation.
