Question

what role does competition play in international trade?
it results in higher prices.

Explanation:

In international trade, competition among producers and exporters leads to more choices for consumers. To attract buyers, firms lower prices. Higher prices are contrary to competitive - market effects. Competition doesn't discourage imports as it can make imported goods more attractive too. And competition doesn't eliminate the need for investment as firms need to invest to be more competitive.
