Which of the following statements best describes the 'forward rate evolution' in the HJM framework?
Question 2
What is the primary purpose of the 'drift condition' in the Heath-Jarrow-Morton (HJM) framework?
Question 3
In the HJM framework, what does 'arbitrage-free parameterization' refer to?
Question 4
Which of the following is a key characteristic of the HJM framework's approach to modeling interest rates?
Question 5
Consider the instantaneous forward rate $f(t, T)$ in the HJM framework. If the volatility of the forward rate is given by $\sigma(t, T)$, the drift condition under the risk-neutral measure is given by: $ \alpha(t, T) = \sigma(t, T) \int_{t}^{T} \sigma(t, u) du $ What does this formula primarily ensure?
