Combinatorial procurement auctions are increasingly being employed in the private and public sector as an alternative to simultaneous single contract auctions. This mechanism has the advantage that it enables suppliers to express synergies across bundles of public contracts. This mitigates the...

The first part of the paper reports the results from a sequence of laboratory experiments comparing the bidding behavior for multiple contracts in three different sealed bid auction mechanisms; first-price simultaneous, first-price sequential and first-price combinatorial bidding. The design of...

This paper presents the outcome of an experiment where the standard one shot sealed bid procurement auction for two identical goods provides the benchmark. Inducing scale economies a combinatorial auction is applied on the situation with non-linear costs. The mechanisms are first run without,...

Non-contractible quality dimensions are at risk of degradation when the provision of public services is privatized. However, privatization may increase quality by fostering performance-improving innovation, particularly if combined with increased competition. We assemble a large data set on...

Controlling for differences in taxes and transportation costs, the Nordic Competition Authorities claims, in a report from 2005, that food prices are 11% higher in Sweden compared to the EU-15 countries. One explanation for this put forward in the report is the limited competition on this market...

The bidding process in public procurement in Sweden is a first-price sealed bid auction. Although there is a competitive effect on the bids in this type of auction, the contracting entity can, through the choice of procurement procedure, restrict the number of bidders. This paper studies this...
