Development economists looked primarily at economic factors like capital, labor and technology as sources of economic growth, and thought neither about the consequences of growth for politics nor the relationship of political institutions to growth. The Harrod-Domar growth model that was dominant in the 1950s suggested that less- developed countries were poor primarily because they lacked capital, which then led development agencies like the World Bank to try to kick start growth with generous infusions of capital for physical infrastructure. It was only when steel plants and shoe factories in sub- Saharan Africa went idle due to corruption or lack of organizational capacity that they were forced to go back to the drawing board. The political scientists, for their part, scaled back their ambitions from large Huntingtonian-style theory and focused primarily on political phenomena.
