What the GAO study is and is not
What it is:
• An independent investigation of a set of mergers in the oil industry in the late 1990s
• A serious effort to investigate the broad impact of the set of mergers where no similar evidence existed in the public record.
• Indication of the potential usefulness of retrospective evaluation

What it is not:
• Not a study of causes of current price changes
