Motivating example: Google, Apple, Microsoft et al were recently fined $430 million for wage collusion and anti-trust violations regarding hiring of employees. Their employees were involved in a class action lawsuit. My uninformed guess is that the wage collusion and anti-poaching agreements adversely affected market wages as a whole for everyone in software. I'd like to know how one might prove that.
To limit the scope of the question a little: how would one go about calculating the impact of anti-poaching agreements on market wages? My intuition for a solution involves brute forcing an implausibly accurate dataset, but I know you economists are clever folks.
