This article summarizes my dissertation on corporate political activities and political institutional environments in international business. It addresses how firms are affected by random (crisis), regular (election), and firm-induced changes in their political environment. The three key findings of my dissertation are that internal and external institutional pressures are not independent of each other; firms´ international and national diversification act as safeguards when political events occur; and non-pivotal corporate political activities are oftentimes underestimated. In its entirety, the dissertation not only sheds light on various political challenges, but also on firms’ strategies in addressing those challenges.
