Hello, I am enrolled in a master in economics program, which is not in North America, and applying for PhD in economics program in North America presently. More than three economics professors agreed to be my referees and I have decided to use recommendation letters of different professors for different programs. However, there is a question: for my dream school, which referee should I choose between the following two professors? Might someone be nice to offer me some suggestion?
One professor has some connection, because he is affiliated with some economics associations in North America and also had cooperation with researchers in North America. However he said he will write the recommendation only based on my performance in his class. Although I achieved good grades in the class, the information is still limited. Another one is my academic advisor, though he has little connection with departments of economics in North America, he knows me very well and would like to write strong recommendation. Since I know recommendation letters are critical for PhD application, I dare not to randomize between them though I have decided the choice of other two referees. Therefore, would someone be kind to give some advices?
