I am a research student currently assigned to a client to carry out economic impact analysis for them. My client is into tourism activity. Unfortunately i have no economics background and have no idea how to carry out such an impact analysis. I have research about it but i am struggling to find a model to use. I would be glad if anyone could help me how to carry out tourism impact study and model that i can use to carry out such study , particularly the model which i can easily get via online.
