Rather than generating tax revenue as do tariffs, subsidies require tax revenue. Therefore, they are not an effective protective device for the home economy. Do you agree?

Yes. Subsidies are benefits that the government can grant to institutions, households and businesses to promote economic efficiency and reduce market failures. They may be distributed through cash or by cutting tax rates. However, there is controversy about the effectiveness of using subsidies for the economy, often related to the inefficiency of promoting a free market, allocating resources that could be used for investment in productive resources and masking the results of economic efficiency. Another major concern with the use of subsidies is the formation of political alliances of those who receive them and those who provide them, creating political interests because of their use.
