陈模型
外观
在金融学领域,陳琳模型(Chen model)是一個數學模型,描述利率的动态演變过程。它是一種“三因素模型”(短期利率模型),因為它所描述的利率變動是由三种市場風險推動的。陈琳模型是第一个隨機均值和隨機波動率的利率模型,由经济学家陈琳发表于1994年。陈琳是哈佛大學毕业的經濟學家,曾為美國哈佛大學,新加坡大學,貝魯特美國大學,韩国延世大學,瑞士金融学院,美林证券,里昂信貸銀行和美国聯邦儲備局工作。
在陈琳模型中,瞬時利率的演变是由以下隨機微分方程决定的:
陳琳模型被全球金融機構广泛采用, 它不但具有实际意义, 同时也具有重要的学术价值。在一份權威的現代金融学文献述评中(“金融学的連續時間方法:回顧與評價” [1]),陳琳模型被列為利率期限結構的主要模型。美国学者詹姆斯和韋伯的教科书有几节專門討論陳琳模型。瑞士学者吉布森等人的利率理论综述也有專門一節介绍陳琳模型。丹麦学者安德森等人的文章专门致力于研究、评估和推廣陳琳模型。美国学者伽伦等人的文章測試和验证了陳琳模型和其他利率模型。 美国博士生蔡在她的博士論文研究中测试陳琳模型和其他競爭模型。
