Optimal order placement in limit order markets
I am reading the paper: https://sci-hub.do/10.1080/14697688.2016.1190030 because I want to split the target shares in market order book and limit order book.
I have a question when it comes to page 10 ...

Poisson modelling of non-life insurance claims with reporting delay
I am considering a portfolio of car insurance policies. In order to capture the individual history (driving skills, age, etc.) of policyholders, it is assumed that the claim numbers $N(t)$ are modeled ...

How to calculate the expectation of Poisson process when its intensity is also stochastic
How to calculate the expectation of Poisson process $N_t$ when its intensity is also stochastic? Since when intensity $\lambda_t$ is non-random, then we have
$$E[dN_t] = \lambda_tdt.$$
But how about ...

Marked poisson process vs compounded
I am a bit fuzzy about difference between compounded poisson process defined as
$$\sum_{i=1}^{N_t} D_i $$
where $N_t$ is poisson process and $ D_i $ are iid random variables
and marked poisson ...

Black-Scholes formula for Poisson jumps
For underlying asset
$$d S = r S dt + \sigma S d W + (J-1)Sd N$$
here $W$ is a Brownian motion, $N(t)$ is Poisson process with intensity $\lambda.$
Suppose $J$ is log-normal with standard deviation $\...

How to simulate a jump-diffusion process?
I would like to price Asian and Digital options under Merton's jump-diffusion model. To that end, I will have to simulate from a jump diffusion process.
In general, the stock price process is given ...

Bond price under Poissonian model of interest rate
Working through an exercise in interest rate modelling and I have the following setup:
$r_t = r_0 + \delta N_t$ where $\delta > 0$ and $\lambda > 0$ is the intensity of the Poisson pricess $N_t$...

Does a Poisson process converge to an Ito process in long term?
I have heard that a Poisson process "converges" to an Ito (diffusion) process in long term. However I do not see how the characteristic function of the form morphs into that of the latter. In what ...

Probability density function of simple equation, compound Poisson noise
I would like to find the probability density function (at stationarity) of the random variable $X_t$, where:
\begin{equation*}
dX_t = -aX_t dt + d N_t,
\end{equation*}
$a$ is a constant and $N_t$ is a ...
