文摘

Compare global returns to scale under convex and nonconvex technologies. First to test special case of global sub-constant returns to scale in nonconvex Free Disposal Hull. First to introduce a method for local returns to scale in nonconvex technologies. Document concordance and conflict between convex and nonconvex global returns to scale. Explore local returns to scale in Free Disposal Hull by tracing ray-average productivity.
