  So their payoff is just 30. They didn't get an education so it was free.
  收益是30 他们不学习也就不用花钱
• 
  
  They get 30 for free, so their payoff is just 30.
  他们得到30的工资因此收益是30

  So here come the bad workers. They find their way into my class in SOM.

  They have a miserable time.
  他们学得很辛苦
• 
  
  I have a miserable time because they're having a miserable time.
  我也因此教得很辛苦

  But at the end of the day they're identified as good workers
  最后他们被认为是好雇员

  and hence they're paid 50.
  得到工资50
• 
  
  And their payoff is 50 - 3 x 10.01 which is approximately 20.
  他们的收益就是50-3×10即20

  Is that right?
  对吧
• 
  
  So they don't want to deviate either and now I'm done,
  他们也不想改变 那我就证明完了
• 
  
  I've shown it's an equilibrium.
  这样我就证明这是个均衡了
