The theory is generally associated with Hirschman . He presented a complete theoretical formulation of the strategy . Underdeveloped countries display common characteristics : low levels of GNI per capita and slow GNI per capita growth , large income inequalities and widespread poverty , low levels of productivity , great dependence on agriculture , a backward industrial structure , a high proportion of consumption and low savings , high rates of population growth and dependency burdens , high unemployment and underemployment , technological backwardness and dualism ( existence of both traditional and modern sectors ) . In a less - developed country , these characteristics lead to scarce resources or inadequate infrastructure to exploit these resources . With a lack of investors and entrepreneurs , cash flows can not be directed into various sectors that influence balanced economic growth .
