讲座内容：

While some of firms’ strategic decisions have positive impact on performance, some do not and may have negative impacts. In this presentation, I will talk about how to evaluate the impact of strategic decisions on firms’ financial and operational performances for both short period and long term. In particular, for the short term, I will present how to evaluate market value changes with three models: the Carhart four-factor model, the market model, and the market-adjusted model. For the long term performance evaluation, I will talk about how to use control firms with different matching methods. Examples from my research will be used to illustrate how to establish the causal relationship.
