We examine the effect of market efficiency on the efficiency of capital allocation in the setting of decentralized exchanges of crypto assets. Utilizing data on nearly 100 million trades in concentrated liquidity pools on two leading blockchains, we construct a highly granular, capital-market-based measure of capital allocation efficiency. We also design and implement a method of identifying market-efficiency-restoring arbitrage transactions among all blockchain transactions and construct arbitrage-based granular measures of market efficiency. We find that market efficiency has positive, economically and statistically significant, and causal impact on capital allocation efficiency.
Anticompetitive Price Referencing

Off-exchange trades are often executed by referencing on-exchange prices. In equilibrium, such price referencing softens market makers' on-exchange competition and makes liquidity expensive for investors. Additionally, by equalizing on- and off-exchange prices, price referencing guarantees “best-execution” and makes investors indifferent where to trade. Market makers effectively obtain a license to fragment orders off exchange, raising their profits but reinforcing market-wide illiquidity. This inefficiency remains tenacious even if more market makers enter and if they are forced to compete off exchange, as in the SEC's proposed order-by-order auction. The model yields important implications for regulating various forms of off-exchange trading.
