(Potential) Number of Bidders and Winning Bids Evidence from the London Bus Tendering Model

Journal of Transport, Economics and Policy, 2013, Volume 47, Number 1, p.17-34, (2013)

In this paper we investigate the relationship between cost and number of bidders for local transportation contracts in London.  Using an original database on 806 calls for tender on local bus transportation routes we find that a higher number of bidders is associated with a lower cost of service.  This finding, in addition of being one of the few empirical tests of a crucial theoretical issue, has important policy implications, especially for countries in which bids are organized such that only few bidders are allowed to participate (e.g. France).  More precisely, our results point out that the allotment of an urban transport network may be a source of significant costs reductions.

Interfirm cooperation in strategic relationships: the role of formal contract

Industrial and Corporate Change, 2012, Vol 21 (4), 811-836

In this article, we use a large database of more than 3700 interfirm relationships in force between French firms in 2003 to study the way they achieve cooperation. We find that cooperation is enhanced by a partner’s reputation. Our results also suggest that while formal contracts have a direct negative impact on ex-post cooperation, they are an enhancing factor of cooperative behaviors as soon as the intrinsic hazards of the relationship require higher ex-ante contractual safeguards to secure agreements.
