Intelligence, Social Mobility, and Growth
构建了一个模型，其中人力资源配置、代际社会流动性与技术增长相互决定。高增长会提高认知能力的回报，使个人配置更依赖先天能力而非社会背景，从而可能形成多重内生增长均衡。
We develop a model where the allocation of human resources, intergenerational social mobility, and technological growth are jointly determined. High growth endogenously increases the equilibrium return to innate cognitive ability and makes the allocation of individuals depend more on innate ability and less on social background. Individuals with a higher level of innate cognitive ability can deal better with less known, but more productive, technologies and thus choose a higher rate of technological growth. A social allocation based on innate ability and high growth will thus reinforce each other, implying the possibility of multiple endogenous growth equilibria.
