A Matching Model with Bounded Holdings of Indivisible Money
修改了货币的随机配对匹配模型，允许个人持有超过一单位不可分割资产，并设定持有上限，研究资产可分割程度对福利的影响。
Recent versions of pairwise random matching models of money with divisible and perishable goods are amended to allow individuals to hold more than one unit of an indivisible asset. The asset resembles a fiat asset, except that nominal holdings of it yield a small amount of utility. There is a general upper bound on the number of units of the asset that individuals can hold. A steady state with trade is shown to exist. The model is applied to study numerically the effect on welfare of the degree to which the asset is divisible.
