I'm skeptical of just a mathematical model without tying it to real data, no matter how hard the researchers try to make it "realistic." You can make a mathematical model that says anything. That said, I did find this part interesting:

Burgess and his colleagues delved into the mechanics of ambition after earlier work found that fisheries performed best when boats stopped searching for more fish once they reached higher-than-average catches. They wanted to see if the mathematics supported the strategy in other realms of life, too.
