We provide open-source software for three different Product-Mix Auctions. (All Product-Mix Auctions are single-round sealed-bid auctions for multiple units of multiple distinct goods.)
- This is a generalisation of the design that is the basis of the "ILTR" auction that is now regularly used by the Bank of England — see paper.
- It permits flexible buyer and seller preferences over an arbitrary number of goods.
Version for Budget-constrained bidders.
- This version was originally designed for the Government of Iceland.
- As in the standard version, bidders simultaneously make sets of bids. In this case, however, each of a bidder's bids can specify a total budget to be spent.
"Positive and negative dot-bids" Version.
- This version extends the standard version to permit all participants (buyers and seller) to express any strong substitute preferences for indivisible goods.
This software is available both as a command-line program pma, and a web application pma-server (all open-source). The latter provides a single-user interface allowing an auction specification to be constructed in a web browser form. We host the web application here and also provide the code so users can host it locally.
