چکیده

This article proposes a model for stock prices which incorporates shot-noise effects. This means, that sudden jumps in the stock price are allowed, but their effect may decline as time passes by. Our model is general enough to capture arbitrary effects of this type. Generalizing previous approaches to shot-noise we in particular allow the decay to be stochastic. This model describes an incomplete market, so that the martingale measure is not unique. We derive the minimal martingale measure via continuous time methods.

Risk measurement and Implied volatility under Minimal Entropy Martingale Measure for Levy process

This paper focuses on two main issues that are based on two important concepts: exponential Levy process and minimal entropy martingale measure. First, we intend to obtain   risk measurement such as value-at-risk (VaR) and conditional value-at-risk (CvaR) using Monte-Carlo methodunder minimal entropy martingale measure (MEMM) for exponential Levy process. This Martingale measure is used for the...

Minimal F Q - Martingale Measures for Exponential Lévy Processes

Let L be a multidimensional Lévy process under P in its own filtration. The f-minimal martingale measure Qq is defined as that equivalent local martingale measure for E(L) which minimizes the f-divergence E [ (dQ/dP ) ] for fixed q ∈ (−∞, 0) ∪ (1,∞). We give necessary and sufficient conditions for the existence of Qq and an explicit formula for its density. For q = 2, we relate the sufficient c...

The Variance{optimal Martingale Measure for Continuous Processes

We prove that for continuous stochastic processes S based on ( ;F;P) for which there is an equivalent martingale measureQ with square-integrable density dQ=dPwe have that the so-called "variance optimal" martingale measure Q for which the density dQ=dPhas minimal L(P)-norm is automatically equivalent to P. The result is then applied to an approximation problem arising in Mathematical Finance.

The Minimal Entropy Martingale Measure and Hedging in Incomplete Markets

The intent of these essays is to study the minimal entropy martingale measure, to examine some new martingale representation theorems and to discuss its related Kunita-Watanabe decompositions. Such problems arise in mathematical finance for an investor who is confronted with the issues of pricing and hedging in incomplete markets. We adopt the standpoint of a ra­ tional investor who principally...

Doubly Stochastic Poisson Process and the Pricing of Catastrophe Reinsurance Contract

We use a doubly stochastic Poisson process (or the Cox process) to model the claim arrival process for catastrophic events. The shot noise process is used for the claim intensity function within the Cox process. The Cox process with shot noise intensity is examined by piecewise deterministic Markov process theory. We apply the Cox process incorporating the shot noise process as its intensity to...
