Corporate Defendants Significantly Outspend Plaintiffs in Expert Witness Arms Races

In new research, Adam Callister, Andrew Granato, and Belisa Pang argue that differing incentives faced by plaintiffs and defendants in “battles of the experts” litigation (like securities suits) leads to structurally higher spending by defendants on expert witnesses. These incentives also apply to any class action suit and many individual suits. They argue that courts should take this dynamic into account and correspondingly be more aggressive in using authority to employ court-appointed experts.
