Term Structure model里面哪些是equilibrium model?

i think everything mentioned on the slide is equilibrium model because they are all based on model assumptions. Model assumptions can vary from model to model. Therefore, you will get different prices from different models and they are all appropriate. Arbitrage, on the other hand, starts from the market price. You assume market price is accurate to begin with. If you get different prices from the market, you are observing an arbitrage.
