Bates Model Jump Percentage Parameters

I am trying to calculate the jump parameters for the Bates volatility jumps, specifically, the mean of the jump percentages, $\mu_j$. For the value of $J$, I am using jumps $|\frac{s_{i}-s_{i-1}}{s_{i-...

Change of Measure for Jump Process with Drift and no Brownian motion

If on $(\Omega, \mathcal{F},\mathbb{P})$, $r>0$ is a constant and $Z_t =\sum_{i=1}^{N_t} Y_i$ where $Y_i$ are i.i.d with $E[Y_i]=L$ denotes the size of the jump and can have distributions like ...

Unique risk neutral measure for jumps or incomplete markets for jumps

I wanted to understand why the market is incomplete in jump-diffusion models. whereas if we have a model following geometric Brownian motion then we can get a risk-neutral measure and hence a complete ...
