A Simple Model of MRP and Salary Determination in Major League BaseballThe MRP and salary determination model should consider 1) revenues are related to individual performance through their effect on team standing 2) the reserve clause reduces player salaries below player MRP

Degree of Monopsonisitic Exploitation of Professional Ball Players Players are generally exploited and to a
large degree Over a career length average players
receive salaries equal to about 11 of their gross MRP and 20 of their net MRP
Star players receive about 15 of MRP Some mediocre players have salaries in
excess of their net MRP
Policy Implications
Place ball players under a contractual arrangement similar to pro football A player can play out his option and become a free agent Player-initiated transfers would still not exist
Long-term contracts Contracts for 5+ years followed by free agency
Completely free labor market will all contracts for a full season negotiated off-season Eliminate economic rents of players

Player is a free agent until a one year contract is signed Contract is exclusively renewable for the owner (reserve clause) Owner may renew sell or terminate the contract Player make accept the terms or negotiate After ownerrsquos ldquofinal offerrdquo player must accept or withdraw from professional baseball
MRP is ldquothe ability or performance he contributes to the team and the effect of that performance on the gate receipts The effect of a player performance on revenue may be direct or indirectrdquo ldquoAbility contributes to team performance and victories raise gate receiptsmdashand
