Economics help please!!?

A tariff and a quota will have the same effect.It will cause the consumer price to increase,called economic rent. In case of tariff, the government will have more tax revenue,compared to the case of quota which the money will go to the pocket of importer. Subsidy will not affect the market. Producers just have money and do anything they want. The government will loose tax money. And the society will get more unsold products.The baby has more headache than the mother.
