The Big Push model is a theory that suggests that economic development requires a coordinated effort in order to be successful. This means that all sectors of the economy need to work together in order to create growth. This model was first proposed by Economist Rostow in his book The Stages of Economic Growth.
The reason why the Big Push model is important is because it provides a framework for understanding how different sectors of the economy can work together to spur growth. It also highlights the importance of government intervention in the economy in order to create conditions that are conducive to growth.
The Big Push model has been criticized for its lack of realism and for the fact that it does not take into account the role of market forces in the economy. However, despite its shortcomings, the Big Push model provides a useful way of thinking about how to achieve economic development.
