What happens when a tariff is lowered

People will buy more things / tariff is a tax just letting you know

One potential benefit to this would be that the people are given more choices with regard to the products that they would want to buy. So if they prefer to buy a lot of foreign agricultural products, then more spending will incur. At the same time, local companies will fight back by making better products which will cause people to spend more. More spending means more taxes. The drawback here is that if the country does not greatly limit foreign goods from coming in, local companies will not survive. 

The answer is monsoons.
