A baseball player is offered a 4-year, $50 million contract which pays him the following amounts at the end of each year: Year 1: $11 million Year 2: $12 million Year 3: $13 million Year 4: $14 million Instead of accepting the contract, the player asks for a contract that has the team paying the same total amount, but payments are equal ($12.5 million a year) and come at the beginning of each year for the 4 years instead of the end of the year (4 total payments). Assuming that the appropriate discount rate is 6% per year, what is the difference in the present value of two offers?
