Creator: Goodfriend, Marvin. and McDermott, John H. Series: Economic growth and development Abstract:
We explain how a long period of slow pre-industrial development triggers an Industrial Revolution that leads to modern balanced growth. Development in the preindustrial period is driven by increasing returns to specialization made possible by a growing population. Increasing access to specialized intermediate goods eventually makes fundamental technological innovation possible. Innovation initiates the Industrial Revolution, after which productivity grows endogenously regardless of population growth. Industrialization reconciles the crucial role of population early on with its weak relation to per capita product in developed economies. Faster population growth speeds early development, though if it results from a highly productive primitive technology, the consequences for development are ambiguous.

Creator: Galor, Oded, 1953- and Weil, David N. Series: Productivity and the industrial revolution Abstract:
This paper develops a unified model of growth, population, and technological progress that is consistent with long-term historical evidence. The economy endogenously evolves through three phases. In the Malthusian regime, population growth is positively related to the level of income per capita. Technological progress is slow and is matched by proportional increases in population, so that output per capita is stable around a constant level. In the post-Malthusian regime, the growth rates of technology and total output increase. Population growth absorbs much of the growth of output, but income per capita does rise slowly. The economy endogenously undergoes a demographic transition in which the traditionally positive relationship between income per capita and population growth is reversed. In the Modern Growth regime, population growth is moderate or even negative, and income per capita rises rapidly. Two forces drive the transitions between regimes: First, technological progress is driven both by increases in the size of the population and by increases in the average level of education. Second, technological progress creates a state of disequilibrium, which raises the return to human capital and induces parents to substitute child quality for quantity.
