2016年度约翰·贝茨·克拉克奖得主尤利伊·桑尼科夫的学术贡献主要体现在将连续时间建模技巧应用到契约理论和博弈论之中,并以金融为主要应用领域,为解决公司金融中的动态激励和融资机制、解释企业的声誉和共谋现象提出了新的研究视角,同时也在金融摩擦和货币政策效应等问题上提出了一系列开创性的方法,从而推动了当代行为金融理论的发展。本文主要从契约理论的基础方法、博弈论在公司金融中的应用和宏观经济模型中的金融问题等角度对桑尼科夫在金融经济学领域的贡献进行梳理和评述。
In 2016, the academic contribution of Juliusz Sonnik, winner of the John Bates Clarke, is mainly reflected in the application of continuous-time modeling techniques to contract theory and game theory. With financial as the main application field, The dynamic stimulus and financing mechanism in corporate finance, the interpretation of corporate reputation and complicity put forward a new research perspective, but also put forward a series of groundbreaking methods on the issues of financial friction and monetary policy so as to promote the contemporary The Development of Behavioral Finance Theory. In this paper, we mainly review and comment on Sonikov’s contribution to the field of financial economics from the perspectives of the basic methods of contract theory, the application of game theory in corporate finance and the financial issues in the macroeconomic model.
