Combinatorial procurement auctions enable suppliers to pass their potential cost synergies on to the procuring entity and may therefore lead to lower costs and enhance efficiency. However, bidders might find it profitable to inflate their stand-alone bids in order to favour their package bids....

We study the effects of politics on public procurement in Swedish municipalities in 1990-98 using data on cleaning services. No procuring municipality committed to a standard auction format or to an explicit scoring rule. Political identity of the governing party is not correlated with the...

We study a reform by which a standardized model of choice and competition was introduced in tax-financed home care in a majority of Swedish municipalities. The market for home care is of particular interest since it is close to the ideal quasi-market. For identification, we exploit the different...

This paper studies the practice of environmental requirements in the allocation of public contracts (Green Public Procurement, GPP) under two different regulation periods. More specifically, the effect of GPP and revised regulation (including increased GPP ambitions) on competition, bids, and...

We compare beauty contests with first-price sealed-bid and scoring auctions, using data on public procurement of cleaning services in Swedish municipalities. The lowest submitted and winning bids are similar in all auction designs despite a higher price sensitivity of procurement bureaucrats in...

During the 19th century, poor and orphan Swedish children were boarded out. The foster-parents' compensation was determined in English auctions. Some children were re-auctioned. We use historical data from such auctions to study whether informational asymmetry and possibly adverse selection...

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...
