This paper examines W. Arthur Lewis’s Dual Sector Model of Development. Lewis, a
founder of Development Economics, has been one of its most significant contributors.
This paper applies the Dual Sector Model to Moldova and Romania and explores the
economic growth occurring in each country. Considerations are made for each country’s
unique situation, and observations not accounted for in the original Model are
acknowledged. Lewis’s Dual Sector Model can be successfully applied to both Moldova
and Romania, although each one is at a different stage economically, and certain
modifications need to be madeconcerning the situation of contemporary developing
countries.
