Hi Jey, welcome to the econ stackexchange. 
Maybe you can clarify your question more and define what RDD you would run. E.g., what is your running variable, what is the estimation equation.
Also, are you looking for causal identification or "just" robust correlational evidence?

My running variable is subsidy amount (fossilf) and I want to estimate the causal effects of subsidy amount on GDP per capita.
