That is, log wages increase with experience, but at a declining rate. a) How does the theory of human capital rationalize this finding? In your answer, make sure to explain the role of on-the-job training, and how it evolves over the life-cycle. b) How does Jovanovic's model of match quality rationalize this finding? c) Is the wage-experience profile steeper for college graduates or for high-school graduates? Can this finding be rationalized by the model you described in part (a)? By the model you described in part (b)? d) Is the wage experience profile steeper for men or for women? Has the shape of the wage- experience profile for women changed over time? Can this finding be rationalized by the model you described in part (a)? By the model you described in part (b)
