Procuring authorities frequently use screening in order to mitigate risky bids. This study estimates the effect of bid screening and litigation on entry and bidding using a unique data set on highway construction procurement auctions in Poland. The market exhibits a screening method that ex post selects eligible offers. We demonstrate with an empirical model that this method disproportionately affects small firms and creates a barrier to entry. Our results suggest that screening increases bids by two channels. First, it directly inflates bids as well as decreasing entry. Second, in a competitive market, lower entry also inflates bids and prices.
