Difference between tarrifs and quota.?

Question

What are their differences? and how each affect domestic price, domestic consumption and domestic production?

Answer 1

The main difference is that a tariff adds a tax to imports, causing the price to go up, and a quota limits the amount of imports.  They both increase domestic price, which decreases domestic consumption and increases domestic production.  The only difference is that the proceeds from tariffs go to the government, and if quota are not auctioned off, the difference between the domestic price and the international price (quota rent) goes to the foreign producers.
