I'm using panel data set. I want to show diffentiated effect of financial development on growth in diffent financially developed countries.
I want to estimate;
Y= bo+b1X+b2(Financial Development)+b3(Financial Development *High Financially Developed Dummy)

I want to construct a High Financially developed dummy, if country is more financially developed 1 and 0 otherwise. Please help me
