While the issues are fairly technical the basic intuition is that the presence of wealth effects (which is the feature that most clearly delineates general equilibrium analysis from partial equilibrium) generates the possibility of multiple equilibria.
虽然该问题相当技术性，其直觉在于财富效应的存在（此为一般均衡分析与局部均衡区别最为显著的特征）产生了多重均衡的可能性。
