Trade in renewable energy products was also sensitive to tariff reduction at the 5 per cent level. It is possible that these two categories comprise high-technology products, most of which tend to be imported by developing countries. Thus the initial list of EGs could be further narrowed to include only these sub-items for the initial round of liberalization. It should, however, be noted that the elasticity of these products with respect to tariffs is low, with a tariff reduction of 1 per cent leading to only a 0.15 per cent increase in trade.
