How Trade Shapes State Economies
Interpreting openness, balances, and growth when the evidence is sub-national rather than only national.
National trade politics often treats “America” as a single unit. State-level flows show which economies live and die by ports, farming exports, advanced manufacturing, or cross-border services.
