The event provides an annual stage for frontier research on the economic analysis of public procurement by bringing together in Mannheim empirical and theoretical economists active in this area with different backgrounds. Around 20 participants from Europe and Overseas gathered this time. The format consisted of nine presentations, followed by a discussion and Q&A with the audience. Topics ranged from the reverse auction design and the implications of contract renegotiation to the analysis of the role of buyers and competition policies.
