Reviewer 3 Report

Dear Authors, 

Thank you for sending your manuscript. 

The following changes are require 

(a) The introduction needs to be redrafted to show the contribution of the study to literature. 

(b) The motivation of the work should be improved.

(c) The short form of the equations should be used.

(d) The author should include policy implications of their result and compare with previous literature. 

(d) The conclusion is poorly written and should not begin with questions. You have done the work and you need to summarise and provide policy strategy as well as direction for future research.

Round 2

Reviewer 2 Report

Thank you for taking my suggestions seriously and for responding adequately.

Some small issues:

1. In line 234 you still write "four" models, but now they are more.

2. Line 408: You have subtracted the mean of the logarithmic variables, not the logarithm of the average, be careful with notation here, the "bar" should cover also the "Ln" symbol, not just "X".

Also perhaps you should mention this earlier, near eq. 18 which is the translog specification.

3. In the translog eq. 18 I do not see the (1/2) factor in front of the Interaction Terms component.

4. Equation  19 is missing in the file I received (I believe it shows how the inefficiency term is specified as a function of Z's).

5. A final round of text editing and continuing improvement of English will not hurt. In general, I detect a tendency to omit the definite article "the", e.g. line 501 should read "How do the independence assumption...", etc.
