Proponents of economic planning for developing countries have argued that the uncontrolled market economy can,and often does,supject these nations to economic dualism,fluctuating prices,unstable markets,and low levels of employment. In particular,they have claimed that the market economy is not geared toward the principal operational task of poor countries:mobilizing limited resources in a way that will bring about the structural change necessary to stimulate a sustained and balanced growth of the entire economy. Planning has come to be accepted,therefore,as an essential and pivotal means of guiding and accelerating economic growth in almost all developing countries.
