This paper experimentally examines the multilateral bargaining games so as to derive some policy implications for real trade negotiations. It shows the following findings: there are significant delays in games including veto players in some circumstance, but no delays in games including multiple-vote players. In addition, non-veto players as weak players, who are disadvantageous in taking share, collusive attempts against veto players, but not effective. As policy implications, this paper suggests enforceable deadline or threat toward low quality agreements to reduce the delay problems. Furthermore, as another remedy for the delays, it suggests the effort to group countries like multiple-vote players in unequal weight games. (The rest is omitted.)
