Abstract: Continues-time finance model are discussed and modified for the purpose of estimating value-at-risk. Kernel method are applied to estimate price density and VaR of Shanghai Stock Index VaR. Comparing with VaR estimated from Black-Scholes geometric Brownian Motion hypothesis, the modified model is better.

Key words: Value-at-risk, price density, kernel smoothing

摘要: 用改进后的连续时间金融模型给出金融资产收益率的价格密度函数的非参数估计,计算了上证A股指数的VaR,与Black-Scholes密度函数下的VaR相比,得到较好的结果。

关键词: VaR, 价格密度, 非参数估计
