Sau's degree is valid everywhere...
over the years Sau has gained lots of attention.. Faculty is really good.. Joining SAU is a good bet. It's recognized as well as educational environment is good there... Recently joined faculty from DSe will take it to the new heights..
moreover,SAU started teaching economics in 2010,the course structure is pretty good,but its far below reputed institutes like isi,dse,jnu,jamia,gokhale,mse
it doesnt have any great reputation in the market
Plus just because a dse faculty is joining Sau will make it amazing,this is like saying srcc's faculty will be joining satyawati will make it better.
sorry for writing it so bluntly
