Liquidity, transaction costs, and reintermediation in electronic markets

Relationships between trading cost, technology, and the nature of intermediation in the trading services industry are discussed. Electronic markets are linked to reductions in trading costs. Lower explicit costs are related to system development and operating costs. Electronic order book information is identified as a means of realizing implicit cost savings. The concept of liquidity management in electronic environments is introduced, and its potential is empirically illustrated. The empirical results suggest new roles for brokerage and exchange operations, and competition between the two. Competitive advantage with respect to the provision of liquidity management services is compared across types of intermediaries.
