Population Growth In the history of advanced economies, population growth was endogenous – induced by accelerated economic growth In the history of advanced economies, population growth was endogenous – induced by accelerated economic growth Population explosion is exogenous Population explosion is exogenous Theory of demographic transition – four phases Theory of demographic transition – four phases (Source: Hayami: Development Economics)

Population Growth Model 1: Malthus – a natural instinct to maximize the number of children: Is this assumption valid now? Model 1: Malthus – a natural instinct to maximize the number of children: Is this assumption valid now? Model 2: Model 2: What are the utilities and disutilities of having children? What are the utilities and disutilities of having children? Can you interpret the diagram for the early stage of industrialization (from 0 to 1) and for the advanced modern society? Can you interpret the diagram for the early stage of industrialization (from 0 to 1) and for the advanced modern society? Both models give the same results for the early stage of development (economic growth increases population) Both models give the same results for the early stage of development (economic growth increases population) (Source: Hayami: Development Economics)
