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...

This paper is an empirical analysis of first-price sealed-bid procurement auctions in Sweden, with and without combinatorial bidding. The data comprises procurement auctions of identical contracts (road resurfacing) with identical bidders conducted under the same time period (2009-2011) in two...

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...
