Hello,

I am trying to estimate the elasticity of substitution of labor across different sectors using GMM, but am encountering some errors.

I think the main error is the following.

“Error using dseries/extract (line 91)  
dseries::extract: Variable ellh is not a member of o!”

What does this error mean?

I’ve attached the relevant files below.

Thank you.

The `steadystate.m` is missing.

Your `csv`-file contains a unicode byte order mark at the beginning that throws off Matlab.
