چکیده

We consider the Constant Elasticity of Variance (CEV) process, reviewing the relationships between its transition density and that of the non-central chi-squared distribution. When the CEV parameter exceeds one, the forward price process is a strictly local martingale, and the price of a plain vanilla European call option reflects this fact. We develop techniques for Monte Carlo simulation of the CEV process, for all parameter regimes, and compare the results against the analytic expressions for plain vanilla European option prices. Using these techniques, we also verify the local martingale property.

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...

A Minimality Property of the Minimal Martingale Measure

Let X be a continuous adapted process for which there exists an equivalent local martingale measure (ELMM). The minimal martingale measure P̂ is the unique ELMM for X with the property that local P -martingales strongly orthogonal to the P -martingale part of X are also local P̂ -martingales. We prove that if P̂ exists, it minimizes the reverse relative entropy H(P |Q) over all ELMMs Q for X. A co...

Multi-Agent Simulation for Promoting Clean Energy Vehicle Considering with Concern for Environment and Local Interaction

Clean energy vehicles such as EV or PHV should be promoted for the reduction of greenhouse gas emission in the transportation section. However, it is pointed out that the social interaction affects the promotion of CEV. Therefore, the multi-agent simulation system for promotion planning of CEV is developed considering with not only concern for environment but also local interaction process as s...

The Existence of Absolutely Continuous Local Martingale Measures

We investigate the existence of an absolutely continuous martingale measure. For continuous processes we show that the absence of arbitrage for general admissible integrands implies the existence of an absolutely continuous (not necessarily equivalent) local martingale measure. We also rephrase Radon-Nikodym theorems for predictable processes. 1.Introduction. In our paper Delbaen and Schacherma...

Testing Whether the Underlying Continuous-Time Process Follows a Diffusion: an Infinitesimal Operator Based Approach

We develop a nonparametric test to check whether the underlying continuous time process is a diffusion, i.e., whether a process can be represented by a stochastic differential equation. Our testing procedure utilizes the infinitesimal operator based martingale characterization of diffusion models, under which the null hypothesis is equivalent to a martingale difference property of the transform...
