A recent lawsuit alleged that a billionaire investor bought the rights to a new drug just to eliminate a potential competitor. We asked Yale SOM's Florian Ederer to explain why a "catch-and-kill" merger can be damaging and what to do about the phenomenon.

A study from Yale SOM’s Florian Ederer suggests that when individuals or organizations don’t fully understand how they’re being ranked, they’re likely to work harder for higher ratings.
