Paternity leave can be a great thing for father/child bonding, and for equalizing opportunity for women (who face greater social/practical pressure to take their leave), who can fall behind male colleagues by taking their leave. Unfortunately, it's hard to force men to take their leave, and in the US a lot of men don't because it is frowned upon socially in many companies.
One possible way to incentivize men to take paternity leave is to do so indirectly, by rewarding companies where a large percentage of eligible fathers take the full leave. This would reverse the current dynamic, which is: if you take the full leave, you're putting your family above the company, and not being a team player. Instead, taking the leave would make you a team player and help the company fulfill the goal.
