A re-examination and analysis ofdata in court records covering sealed-biddingpractices, market shares, incumbency rates, andprofit margins of two dairies charged with bid-riggingdisclose that Scott's analysis is flawed in severalimportant respects: reliance on selective bid data,omission of relevant bid data, and errors in reportedbids.
