The article discusses how parties in a contract decide whether to give control to the boss or the worker. When authority is given to the worker, they choose a project and work hard to complete it. This setup motivates the worker to put in effort by letting them pick projects they like, but it can also lead to inefficient choices. Overall, giving authority to the worker is better for parties who are not very patient, while keeping control with the boss is better for those who are more patient.
