In this note, we provide a very simple mathematical model for analyzing the effect of economic sanctions on quality of students who decide to emigrate from a country which has economic sanction exposure. Our model's results suggest that applying decisions for foreign universities are based on quality of students but probability of economic sanctions as well as its costs have great impact on this decision. Furthermore, the model provides results which are consistent with empirical findings especially the positive relationship between cost of emigration and quality of applying students.
