His model was subsequently formalized by John Fei and Gus Ranis, who ended up at Yale. Ranis also made the first formal empirical application, looking at. from phase one to phase two growth, as defined in the Lewis-Ranis-Fei model. This implies that phase three growth could be achieved by the commercialisation. The upcoming discussion will update you about the difference between Lewis model and Ranis-Fei model. According to Rains-Fai point (end of the first phase) .
