同学你好。
这个要从他们最基本的定义来理解,而不是对比两个公式哪个公式字母多。
1.Equilibrium term structure models are models that seek to describe the dynamics of the term structure using fundamental economic variables that are assumed to affect interest rates. 均衡模型用的参数是基本面经济变量。
2.In arbitrage-free models, the analysis begins with the observed market prices of a reference set of financial instruments and the underlying assumption is that the reference set is correctly priced. 无套利模型用的是参考金融工具的市场价格。
3.对比所使用的的参数,明显均衡模型需要的参数更少。
