This paper shows the equivalence between the stable solution set of an
y cooperative game in characteristic form (G1) and the subgame perfect
Nash equilibria in pure strategies of a certain noncooperative game (
G2). Players of G1 are named ''agents.'' G2 is played by different pla
yers (''principals'') who compete in wages to attract agents. The equi
valence result holds when there are enough principals (if the game is
superadditive, two principals suffice). Finally, another related coope
rative game (G3) is constructed with both principals and agents as pla
yers. For G2 and G3 the same result is then proven, for any number of
principals. Journal of Economic Literature Classification Numbers: C71
