President Pranab Mukherjee today said that dynamic nature of world calls for adopting and developing appropriate public policies. Speaking to a group of students of Indian School of Business, Mohali, who had called on him in New Delhi, Mr Mukherjee noted that a good public policy with poor implementation is of no value to the nation. He said the scale and speed of changes happening around the world are unprecedented and so are the challenges. <br/><br/>He said, what is read in literature about public policy today will change in few years and it calls for constant upgradation of skills and knowledge even on the part of the specialists. He said human capacity has been a key determinant in the rise of nations. He said, even today, the race among nations is not necessarily won by those with immense resources, but by those who have the capacity to make the most effective use of those resources for building the nation. <br/><br/>The President said, that capacity is directly related to the ability to make effective public policies and to implement these policies effectively. The President said the treatise of Chanakya on public policy discourse has always been a guiding force in the area of public finance, urban governance, security and diplomacy. He added that Public policy is an area of study which has great relevance to the continuing task of nation building.
