Explanation:

Trade can be defined as a process which typically involves the buying and selling of goods and services between a producer and the customers (consumers) at a specific period of time.

Basically, trade can be categorized into two (2) main groups and these are;

I. Import: this involves bringing in goods from a foreign country to sell in a different (domestic) country.

II. Export: it involves the sales of goods produced in a domestic country to a foreign country.

An export subsidy can be defined as any government policy that encourages the export of goods to other countries while discouraging the sales of goods in the domestic market through the use of tax reliefs, low cost loans, government foreign adverts, etc.

A surplus is the amount by which the quantity supplied of a good exceeds the quantity demanded of the good.

Producer surplus is the amount a buyer is willing to pay for a good minus the cost of producing the good.

Consumer surplus is the amount a buyer is willing to pay for a good minus the amount the buyer actually pays for it.

Hence, an export subsidy will increase producer surplus, decrease consumer surplus, decrease government revenue, and decrease overall domestic national welfare.
