应pc加拿大预测准确率概率统计研究所邀请，新加坡国立大学数学系Class of 62讲座教授寇星罡（Steven Kou）教授将于近期访问我校并作系列学术报告。

     报告一： Simulating Risk Measures
     时   间：10月19日（星期三）下午2:00
     地    点：齐云楼911报告厅.
摘要：Risk measures, such as value-at-risk and expected shortfall, are widely used in risk management, as exemplified in the Basel Accords proposed by Bank for International Settlements. We propose a simple general framework, allowing dependent samples, to compute these risk measures via simulation. The framework consists of two steps: In the C-step, we control the relative error in the simulation by computing the necessary sample size needed for simulation, using a newly derived asymptotic expansion of the relative errors for dependent samples; in the S-step, the risk measures are computed by using sorting algorithms. Numerical experiments indicate that the algorithm is easy to implement and fast, compared to existing methods, even at the 0.001 quantile level. We also give a comparison of the relative errors of value-at-risk and expected shortfall. This is a joint work with Wei Jiang.

    报告二： The Science of Money

    时   间：10月19日（星期三）下午3:30
    地   点：齐云楼911报告厅.
摘要：We will discuss three aspects of the application of scientific methods to finance. Although more advanced tools, such as stochastic differential equations, Monte Carlo simulation, psychology, statistical inference, optimization, and functional analysis may be needed to study these topics, only high school mathematics will be used in the talk. We aim at giving some concrete examples in these topics, to inspire interests among the general public. In particular, we will focus on three examples: (1) Optimal portfolio choices, e.g. Kelly and Merton criteria. (2) The binomial model for option pricing.
