Stock Price Processes with Infinite Source Poisson Agents
fractional Brownian motion arbitrage stock price model stable L´ evy motion long-range dependence self-similarity
2011/7/5
We construct a general stochastic process and prove weak convergence results. It
is scaled in space and through the parameters of its distribution. We show that
our simplified scaling is equivalent ...
Optimal Dividend Payments for the Piecewise-Deterministic Poisson Risk Model
Piecewise-deterministic compound Poisson model optimal stochastic control HJB equation quasi-variational inequality threshold strategy barrier strategy
2011/7/5
This paper deals with optimal dividend payment problem in the general setup of a
piecewise-deterministic compound Poisson risk model. The objective of an insurance
business under consideration is to...

The claim experience of the past is a very important information to calculate the fair price of an insurance contract. In a lot of European countries for instance the prices for motor car insurance d...
Segmentation algorithm for non-stationary compound Poisson processes
Segmentation algorithm non-stationary compound Poisson processes
2010/10/18
We introduce an algorithm for the segmentation of a class of regime switching processes. The segmentation algorithm is a non parametric statistical method able to identify the regimes (patches) of th...

The aim of this paper is to study the construction of prospective mortality tables from a low number of persons subjected to risk. The presented models are the Lee-Carter and log-Poisson methods resp...
对理赔到达为复合PoissonGeometric过程的风险模型进行了推广,建立了双复合PoissonGeometric风险模型,即保单到达与理赔到达均为复合PoissonGeometric过程的风险模型并对其进行了研究,证明了基于此模型的调节系数是不存在的。并进一步考虑到保险经营中的随机因素,将模型推广为带干扰的情形,得到了破产概率表达式及其上界。
A Multivariate Poisson Model of Consumer Choice in a Multi-Airport Region
Airport Choice Poisson Regression Expectation Maximization

Using the results of a unique telephone survey the frequency of consumer flights from airports in a multi-airport region are modeled using a multivariate Poisson framework, the parameters of which wer...
保费与理赔相关的复合Poisson风险模型
Poisson风险模型 理赔 保费
2009/7/2
研究一类相依风险过程，其中保费收入为复合Poisson过程，且索赔产生时以概率的可能性同时产生一次续保。运用鞅方法得出破产概率满足的Lundberg不等式和一般公式，给出当收取的保费和索赔额及续保保费均为指数分布时破产概率的具体表达式,并通过数值计算分析了初始资本、期望理赔额及续保率对保险公司破产概率的影响.
Scaling and memory in the non-poisson process of limit order cancelation
Econophysics Inter-cancelation duration Scaling Long memory Multifractal nature
2010/11/2
The order submission and cancelation processes are two crucial aspects in the price formation of stocks traded in order-driven markets. We investigate the dynamics of order cancelation by studying the...
Model uncertainty in claims reserving within Tweedie's compound Poisson models
Claims reserving model uncertainty Tweedie’s compound Poisson model Bayesian analysis model selection model averaging Markov chain Monte Carlo
2010/10/29
In this paper we examine the claims reserving problem using Tweedie’s compound Poisson model. We develop the maximum likelihood and Bayesian Markov chain Monte Carlo simulation approaches to fit the m...
