Bridging the gap between quantitative and qualitative methods, this article highlights how synthetic control methods can systematically select comparison units for empirical research. The approach allows for precise statistical inference even with small sample sizes while leaving room for traditional case study techniques.

Case Study Focus: Using West Germany following reunification as a prime example, the paper demonstrates how to estimate reunification's economic impact quantitatively.

Methodological Innovation: Synthetic controls offer a structured alternative to ad hoc comparisons by blending numerical rigor with qualitative understanding.

Practical Significance: This technique equips political scientists with tools that can support detailed analysis and nuanced interpretation of complex events.
