hi
i am using stata and "sfcross command" for calculating profit efficiency with cross sectional data. 3variable inputs and 2quasi-fixed inputs. i have some questions.
1) How to apply or test the properties of the profit function? like monotonicity, convexity and ...Is it necessary to test these at all?
2) Does estimating a profit function have a specific command? Or the software itself detects?
3) What is a one-step command estimate for my model?
please help me. thanx
