Before the 1980s, a mono-disciplinary approach was applied to define economic development. Economic development basically meant sustained increase in per capita income.

This notion of development was prevalent among many of the third world countries until the end of the 1960s. However, during the last quarter of the twentieth century, a multi-dimensional concept of economic development was developed. One of the shortcomings of deﬁning economic development in terms of sustained increase in per capita income is that it fails to accommodate the question of distribution of income.
