The third major source of bad taxes can be customs. Integration with the world economy is central to India’s growth strategy. When India shut itself off from the world economy, it stagnated. When India opened up to the world, this brought competition and new ideas, and the country progressed. Every interference with India’s economic integration is inconsistent with India’s quest for high GDP growth. Customs duties reduce competition in India, and hold back the flow of new ideas into the economy. Customs duties, thus, must be levied judiciously.
