Another prerequisite of course is greater cooperation among the chief ministers. Karnataka and Andhra Pradesh may be attracting the largest investments in software investments, but they are not advancing their interests by competing to build international airports. Where are the international traffic volumes to justify airports in both the metros Instead a better option would be to build a six-lane highway linking both the capital cities and encourage industrial estates to come up along the route which would develop the backward regions in both states. Similarly, both Karnataka and Andhra can harness their information technology capability to better serve the automobile industry in which Tamilnadu is preeminent. Kerala is similarly a frontrunner in the tourism business which the other southern states can learn from and evolve joint packages. There are many other possibilities for mutually beneficial cooperation. But a beginning indeed can be made in harmonising their tax regimes, rules and regulations including uniform subsidy policies. The EU in fact requires common monetary and fiscal policies among member states. An economic union of southern states should therefore aim for a broad convergence in their respective policy regimes. This will ensure that investments and skills diffuse through the region on efficiency and comparative advantage grounds rather than a race to the bottom. A spirit of cooperation than competition will definitely ensure the southern unions success.
