在本文裏，我們檢視幾個利率架構模型在上限選擇權市場的表現。我們所挑選的模型一方面可以補捉隆凸型的波動，一方面也存在封閉解。我們以一般化的Vasicek模型作為比較的基準，實證的結果顯示GGV與本文所建立的GGVT模型都是非常適當的選擇。

In this article, we evaluate the performance of several term structure model s for the cap market. We concern ourselves with the whole yield curve models that can capture the volatility hump while still remain analytically tractable. The generalized Vasicek is used as a benchmark model for comparison. Our results show that GGV and the proposed GGVT model s are decent choices.
