On the Distribution of Money Holdings in a Random‐Matching Model*
研究随机匹配模型中货币持有的稳态与非稳态分布，推导最优货币量，并证明在成本不太高时，最优货币量的任何分布都会渐近收敛到均匀分布。
This article studies stationary and nonstationary distributions of money holdings in a random‐matching model. The first part characterizes the stationary distributions of money holdings and derives the optimum quantity of money. The second part considers nonstationary distributions of the optimum quantity of money to show that if the production costs are not too large, any distribution of the optimum quantity of money converges asymptotically to the uniform distribution.
