Suppose that Russell Wilson is negotiating a contract with the Seattle Seahawks. Wilson has an offer from the Las Vegas Raiders for $30 million a year. If he signs with the Seahawks, they will earn $60 million in revenue from the signing. The Seahawks next best option is to sign Josh Allen. They would earn $45 million from signing Allen and would pay him a contract of $25 million. Russell Wilson and the Seahawks have equal bargaining power in the sense that they will split the surplus evenly.

a) What is the negotiated salary between Wilson and the Seahawks under Nash Bargaining? What is Wilson's surplus and what is Seahawks surplus?

b) Suppose that the Seahawks know about an injury to Josh Allen, such that they would only earn $30 million in revenue from signing Allen but would only have to pay him a contract of $20 million. What is the new negotiated salary between Wilson and the Seahawks under Nash Bargaining? What is Wilson's surplus and what is Seahawks surplus?
