The R-script 'Code_Imhof_Wallimann' is the code of the paper by David Imhof and Hannes Wallimann: Detecting bid-rigging coalitions in different countries and auction formats published in the International Review of Law and Economics (https://doi.org/10.1016/j.irle.2021.106016). If you use our data, please quote the paper.

In addition, we provide the following data sets prepared for the paper:
- Okinawa cartel (see also Ishii, 2014, Huber et al., 2020): 'Japanesedata'
- Swiss cartels (see also Wallimann et al., 2020): 'Swissdata'
- Italian cartels (see also Conley and Decarolis, 2016): 'Italiandata'
- Robustness analysis (see also Wallimann et al., 2020):
(1) Swiss cartels with additional predictors: 'Swissdata_addpred'
(2) MISSING YET: Swiss cartels with coalitions of two firms
