N. Sh we test for constant return to scale by imposing restriction that alpha plus beta equals to 1 and this will be null hypothesis. If we are able to reject this then no constant return to scale if p value will be less than 0.05. thanks
Thank you sir! That means my study shows decreasing returns to scale. Is that acceptable? In most of the studies I have seen the value more than 0.05. Does it mean something is wrong with my variables?
Thank you so much for making this video, it helps a lot
and what commands do you use if you are using a time series?
Hi ! Thanks a lot for your help ! Have you any idea on how to run Aw, Chen and Roberts productivity index methodology on stata ?
where can I find the data to practice?
Could you elaborate on why we don't get coefficient for materials? Do we recover it in second stage?
Please spec test revealed that the database structure is not adabtable with a pannel model. can I apply this method of L and P on this database?
Thank you sir for this vidéo.
Please how can i verify the hypothesis of the model?
I can't predict TFP because the stata keeps rejecting the option omega. how can I install the command?
Hi! Thanks for this video! I have an average TFP of 15. This seems too high. Did I do something wrong. All values are ln ....
Sir, if the p value of Wald test of constant returns is 0.000, what does that mean? Should it be always more than 0.05? Please reply.

@@sacredheart36 please, how can i do the validate the lp model?
Thank you so much sir
Hello, what is the vgo in your stata
what is the vgo in your equation?
Levinsohn and Perrin estimation should not be used as elasticity of output wrt labour is not probably identified.
Thank you
