How are the implied values and their standard errors calculated here? Thank you in advance.
We have this production function with $\alpha+\beta<1$.
$Y$ output, $K$ physical capital, $H$ human capital, $A$ technology.
There are cross-section data for a number of countries, found in the appendix here: http://eml.berkeley.edu/~dromer/papers/MRW_QJE1992.pdf
The model is:
$I/GDP$ is $s_k$ and $SCHOOL$ is a proxy for $s_h$.
I'm unsure about how to find the implied values of $\alpha$ and $\beta$ and their standard errors.
