我们研究的机制,实现林达尔或瓦尔拉斯分配和纳什均衡是动态稳定的广泛的自适应动态的设计。我们认为,超模块化是不是一个理想的稳定性标准,在这种机制的设计背景下,而不是集中在收缩机制。我们提供了必要和充分条件的机制,纳什实现林达尔或瓦尔拉斯分配,表明这些条件是不一致的收缩属性时,消息空间是一维的,然后展示如何使用额外的维度,以实现动态稳定,同时获得预算平衡的平衡。
We study the design of mechanisms that implement Lindahl or Walrasian allocations and whose Nash equilibria are dynamically stable for a wide class of adaptive dynamics. We argue that supermodularity is not a desirable stability criterion in this mechanism design context, focusing instead on contractive mechanisms. We provide necessary and sufficient conditions for a mechanism to Nash implement Lindahl or Walrasian allocations, show that these conditions are inconsistent with the contraction property when message spaces are one-dimensional, and then show how to use additional dimensions to achieve dynamic stability while gaining budget balance out of equilibrium.
