Innovation plays a key role in economic growth. In this paper, we investigate the effects of intermediate input tariff reduction on the innovation activities of domestic firms.

When the weight given to the domestic firm's profit in the government's objective function is relatively small, it is shown that no AD duty should be imposed if the foreign firm reports its own costs,...
