RT Monograph SR 00 A1 Gagnepain, Philippe A1 Martimort, David T1 Collusion in Bidding Markets: The Case of the French Public Transport Industry YR 2025 FD 2025-03-31 VO 25-1631 SP 30 K1 Bidding Markets K1 Market Sharing K1 Collusion K1 Innovation K1 Public Transport AB We explore empirically the impact of the market sharing collusive practices that were implemented in the French public transportation industry between 1994 and 1999. We build a structural model of bidding markets where innovating firms compete for the market and have the ability to spread the benefits of their innovation through all markets on which they are active. Each local competitive environment shapes the distribution of the prices (the bids) paid by public authorities to transport operators. We recover empirically the distribution of prices and innovation shocks and we show that collusive practices had overall a limited impact on prices. Firms were in reality more interested in avoiding significant financial risks inherent to the activity, as well as the high cost of preparing a tender proposal. As a by-product, we perform a counterfactual analysis that allows us to simulate how an increase in firms’ innovation reduces prices significantly.
