The largest body of work I know of is Punished by Rewards by Alfie Kohn, with over 50 pages of citations of studies proving over and over that coercive methods simply do not work on humans. Extrinsic motivation does not magically transform into intrinsic motivation. Instead, coercion causes irreparable harm on parent/child relationships and damages intrinsic motivation. Humans are not birds nor rats so conditioning and reinforcement do not work as intended. They do work to give the enforcer a sense of power and sadistic pleasure but do not teach anything valuable beyond “violence and bullying work.” Are these your primary goals?
