Excess Capacity as a Commitment to Promote Entry
提出主导企业持有过剩产能并非总是反竞争，反而可作为对上下游企业的承诺，防止机会主义行为，从而促进进入并提升社会福利。
Excess capacities held by a dominant firm are usually viewed as ant icompetitive because they constitute a barrier to entry. This paper explores an alternative reason for a dominant firm to hold excess capacities: they serve as an assurance to upstream (or downstream) companies that the dominant firm will not behave opportunistically once they have made their sunk investments. Excess capacities held for this reason lead to a welfare (Pareto) improvement.
