Military Service of Politicians, Public Policy, and Parliamentary Decisions

How do politicians with past military service decide on societal issues? We explore the voting behavior of parliamentarians in the informative institutional setting of Switzerland with a conscription army. Our setting allows controlling for voter preferences and party ideology. Results show that politicians who have served in the military do not differ from those who have not served when comparing their voting behavior on issues related to female welfare and welfare of the weak and disabled. However, politicians who have served in the military tend to have a higher probability to accept proposals on neutrality and a lower probability to accept proposals linked to international human rights and the environment. We explore differences with respect to military ranks and ideological positions within parties and find that having chosen to serve in higher military ranks is associated with a differential voting pattern. This suggests that motivation for the military affects voting in parliament.
