44. Method of Reflections

45. Method of Reflections Product p1 Degree (Countries) Degree (Products) k=2 Country C1 k=3 Product p2 k=2 Country C2 k=4 k=1 Product p3 k=1 Country C3 k=3 Product p4 Diversification Ubiquity

46. Method of Reflections k1= Standardness: Average ubiquity of products exported by a country Mirror k=2 Product p1 k1,1=7/3 Country C1 Country C1 k=2 Product p2 k2,1=2 Country C2 k=1 Country C2 Product p3 k3,1=3 Country C3 k=3 Country C3 Product p4
