Final answer:
In this business scenario, duopoly dynamics and game theory predict that Warner Music and UMG will base their decisions on how many artists to sign on strategic considerations, with different outcomes depending on whether the game is played once or repeatedly.
Step-by-step explanation:
The scenario described represents a duopoly situation involving Warner Music and UMG, where they need to decide how many new artists to sign each year. The revenue payoff for each scenario depends on their individual and collective decisions regarding the number of artists they sign and the subsequent market price per song that results from those decisions.
Scenario 1: If one label signs 20 artists and the other sticks with 10, the first label's earnings would be 20 artists × 3 million songs/artist × $0.75/song = $45 million, while the second label would make 10 artists × 2 million songs/artist × $1.25/song = $25 million.
Scenario 2: If both labels sign 20 artists, they would both earn 20 artists × 4 million songs/artist × $0.30/song = $24 million each.
In a single play scenario, both firms might opt for a higher number of artists to avoid being undercut. If this game is played once, each producer will likely sign 20 artists, and the price of a song will be $0.75. However, if played annually, they might strategize differently to maintain prices and consumer surplus, potentially settling for a higher price and fewer artists to avoid a race to the bottom. This reflects strategic behavior similar to game theory principles.
