3. Decision Making (1) 4. Repeated Games<br />

Bargaining Costs<br />

Agent 1 pays c 1 , agent 2 pays c 2 .<br />

Protocol: After each round, the roles change<br />

and the fee is subtracted (c 1 from agent 1, c 2<br />

from agent 2). Therefore the game is finite.<br />

c 1 = c 2 : Any split is in subgame perfect<br />

Nash-equilibrium.<br />

c 1 < c 2 : Only one subgame perfect Nash<br />

equilibrium: Agent 1 gets all.<br />

c 1 > c 2 : Only one subgame perfect Nash<br />

equilibrium: Agent 1 gets c 2 , agent 2<br />

gets 1 − c 2 .
