Entry and Subcontracting in Public Procurement Auctions
利用公共工程拍卖数据，采用双重差分法研究不同拍卖形式（第一价格拍卖与平均价格拍卖）如何影响企业的进入决策和分包行为。
We empirically study how the interplay between entry and subcontracting choices is affected by the use of different auction formats in public procurement. The difference-in-differences strategy used exploits a data set of auctions for public works run alternately under first price and average bid auctions. We find that the use of first price auctions causes a marked decline in both entry and subcontracting. We also find that the type of firms entering first price auctions changes with firms becoming more likely to bid jointly with other firms in ad hoc joint ventures.
