The dual-sector model is a model in developmental economics. It is commonly known as the Lewis model after its inventor Sir William Arthur Lewis, winner of the Nobel Memorial Prize in Economics in 1979. It explains the growth of a developing economy in terms of a labour transition between two sectors, the capitalist sector and the subsistence sector.

Famous quotes containing the word model:
“The Battle of Waterloo is a work of art with tension and drama with its unceasing change from hope to fear and back again, change which suddenly dissolves into a moment of extreme catastrophe, a model tragedy because the fate of Europe was determined within this individual fate.”
—Stefan Zweig (18811942)
