A great read about the history of French Timber auctions: Marty Preget, "A Socioeconomic Analysis of French Timber Auctions", 2010. And our structural view on what's happening there, in the paper: Andreyanov, Hadi, "Secret Reserve Prices by Uninformed Sellers", 2021.
French timber data was collected by Preget and Waelbroeck (PW for short) for their 2012 paper and later shared with us. We translate from French and recast the data into two dataframes: long and wide. Long has a format of per-bidder observations, while wide is per-auction.
