Center node: "non cooperative games with preplay negotiations"
  Abstract: We consider an extension of strategic normal form games with a phase of negotiations before the actual play of the game, where players can make binding oers for transfer of utilities to other players after the play of the game, in order to provide additional incentives for each other to play designated strategies. The enforcement of such oers is conditional on the recipients playing the specied strategies and they eect transformations of the payo matrix of the game by accordingly transferring payos between players. Players can exchange series of such oers in a preplay negotiation game in an extensive form. We introduce and analyze solution concepts for normal form games with such preplay oers under various assumptions for the preplay negotiation phase and obtain results for existence of ecient negotiation strategies of the players.
