In any negotiation, a key variable influencing the protagonists' behavior, hence the outcome, is what failure to reach an agreement would cost each of them. In this case, the issue is the cost of Greece's exit (“Grexit") from the eurozone – a prospect that was widely discussed in the media throughout the recent negotiation, with considerable speculation about the stance of the various players, especially the Greek and German governments.
在任何谈判中，一个影响参与者行为进而决定最终结果的关键变量是不能形成一致会给双方带来多大成本。在希腊的例子中，这一成本便是希腊退出欧元区（希腊退出）的成本。在最近的讨论过程期间，媒体广泛讨论了希腊退出的情景，并且就各参与方的立场（特别是希腊和德国政府）做出了各种猜测。
