n autarky, suppose that equilibrium sugar price is $100 per ton in Birdonia, a small agricultural nation. Now, suppose Birdonia engages in free trade with the rest of the world. The world price of sugar is $125 per ton.What will happen to the domestic price of sugar in Birdonia

the domestic price of sugar will increase to $125.

Explanation:

Since the world price of sugar is higher than the domestic price, domestic producers of sugar will export their products in order to earn a higher profit. That will eventually lead to an increase in the equilibrium price from $100 (former equilibrium price) to a higher price equal to the world price ($125).

The domestic variety is cheaper because there is no import duties or no charges imposed on it because of the import from other countries.

Explanation:

A country produces a lot of goods and services in it's own economy using the resources which are present in it's own country. But the goods and the services that are not available in the country but are demanded by the citizens of the country are imported from other countries.

When these goods and services are imported from other countries then there is an imposition of duties or taxes on those goods making the charges of those goods high. With the transportation of the goods from one country to the other, then also some cost is imposed on the good. This increases the cost or the price of the good.
