lmprovement of Portfolio Models Research:An Empirical Study of Corporate Social Responsibility
摘要
Abstract
In this paper, we study corporate social responsibility ( CSR ) through the prism of investors in the process of portfolio.In order to study CSR, we extend traditional portfolio model to five objectives portfolio selec-tion model by adding CSR index as objective functions in Markowitz mean-variance.We extend traditional utility function and prove that the new function is efficient.We measure the typical corporate CSR performance by the mainstream evaluation criteria.The new model has five objectives which include expected returns, variance, the core stakeholders, dormant stakeholders and edge stakeholders.We formulate portfolio by selecting 10 points on the surface of the minimum variance portfolio.The multi-objective formulation is tested by randomly choosing nondominated portfolios with out-of-sample data to testify efficiency.We find that part of portfolio returns are sig-nificantly higher than market returns in the same period.It shows that the formulation can not only help investors to control the CSR directly, but also prove the advantage by actual data, which can provide one method and an idea for investors who focus on CSR.关键词
