Time preferences and political regimes: Evidence from reunified Germany

We use the separation and later reunification of Germany after World War II to show that a political regime shapes time preferences of its residents. Using two identification strategies, we find that former residents of the German Democratic Republic exhibit a significantly less pronounced present bias when compared to former residents of the Fed- eral Republic of Germany, whereas measures of patience are statistically indistinguishable. Interpreting the years spent under the regime as a proxy for treatment intensity yields consistent results. Moreover, we present evidence showing that present bias predicts choices in the domains of health, finance, and education, thereby illustrating lasting repercussions of a regime's in uence on time preferences.
