International trade allows a small economy to take advantage of economies of scale, access a variety of products and services, and obtain resources.
Step-by-step explanation:
International trade allows a small economy to take advantage of economies of scale by accessing a larger market. By exporting goods to other countries, a small economy can increase its production and reduce costs. This can lead to greater efficiency and competitiveness. International trade also provides access to a variety of products and services that may not be available domestically, and it allows countries to obtain resources they may not have in abundance.
