The Brattle Group has expertise in supporting testimony at the class certification stage of antitrust class action litigation. We have supported top-tier academics by performing statistical analyses of detailed sales data and by analyzing market structure to aid the court in deciding whether a purported class meets the requirements set forth by Rule 23. These analyses include regression analyses of sales data to address price dispersion, which is increasingly required to meet the evolving standard of proof for class certification, analyses of entry costs, and analyses of market structure.
