How to discard non-satiation and free-disposal with paper money
论文证明当存在纸币时，即使消费者可能饱和，竞争均衡仍然存在且弱帕累托有效，解决了因饱和导致的均衡不存在问题。
It is well known that a competitive equilibrium may fail to exist when preferences are possibly satiated. We show that this non-existence problem does not arise if one of the commodities is paper money. Moreover, and equilibrium is weakly Pareto efficient in the economy with money. This paper therefore gives an economic solution to the classical problem of non-existence of competitive equilibria caused by satiation.
