Tariffs

A tariff is a tax that a government imposes on imported goods. It increases the cost of imported goods, making them less competitive than domestically produced goods, thereby protecting domestic producers from international competition.

Suppose a country imposes a tariff on imported coffee beans.

With the tariff, coffee bean prices increase, reducing consumer surplus from the area between the demand curve and the world price line to the area under the higher price. This decrease reflects both the higher price paid and the reduced quantity purchased.

Domestic producer surplus increases because domestic producers can sell their coffee beans at a higher price. The area above the supply curve, below the higher price curve, and above the original price curve represents the increased producer surplus.

Also, tariffs generate revenue for the government. It is calculated by multiplying the tariff rate by the quantity of imported coffee beans.

The imposition of a tariff also leads to deadweight loss. These areas indicate the overall loss in economic welfare due to reduced consumption and production inefficiencies.
