Actually my research is on economic growth theory, and I'm doing some
empirical work on Emerging Market Economies (24 countries) between
1991-2016 period.

For searching the growth spillovers, I've used the geographical distance
weighting matrix (exogenous) to estimate my growth regression. (SAR with FE)
But I decided to change the definition of space for Emerging Markets,
because they don't have exact similarities on geographical basis. Therefore
I'm planning to create an institutional weighting matrix for my estimation
and it is time variant, which makes also an endogeneity problem too.
Do you suggest me any estimation method? I was planning to do it again on
ML estimation, but maybe Bayesian will work better? But I don't know how to
do it. Could you please help me.

Thanks,
Merve Aksoylar
