Question

Why might a low-income country put up barriers to trade, such as tariffs on imports?

Short answer

To protect domestic industries.

Step-by-step solution

Step 1. Definition

Trade barriers refer to the restrictions imposed by the government on the inflow of trade in the economy. Tariffs, quotas, and standards are some examples of trade barriers.

Step 2. Explanation 

The inflow of trade introduces competition in the market. Consumers are benefited from lower profits and greater variety in the market. However, trade can also be harmful as some industries might not be able to survive foreign competition. If such firms are driven out of the market it may lead to job loss.

So, low-income countries impose trade barriers to protect infant industries from foreign competition.
