The concavity exercise asks students to think about erosion in natural forms and how that concavity contrasts with the convexity of the objects. Dominant, subdominant, and subordinate relationships ...

Most investable assets and strategies tend to cluster into two broad groups - productive and scarce. Practitioners who are aware of the concave and convex nature of productive and scarce assets and ...
