Final answer:
Directly dealing with foreign-based retailers is mainly efficient because it eliminates the need for intermediaries, which streamlines the supply chain and may lower costs, amongst other benefits like improved business relationships and quicker adaptation to market changes. Therefore, the correct option is D.
Step-by-step explanation:
Dealing directly with foreign-based retailers is efficient because it eliminates the need for intermediaries. This streamlining of the supply chain can lead to a reduction in costs, time, and complexities associated with trade. When a business engages in direct trade, it can better manage its inventory, have more control over the distribution process, and reduce the number of touchpoints where errors or delays might occur. As a result, companies may enjoy lower costs and increased efficiency. Further benefits include the potential for stronger business relationships, quicker response times to market changes, and a more transparent flow of goods. The reductions in tariffs, quotas, and other trade barriers, along with improved transportation and communication media, enhance this efficiency and make it easier for companies to engage in direct international trade.
In the context of global trade, dealing directly with foreign-based retailers allows even small economies to take advantage of economies of scale and benefit from competition and variety offered by multiple producers, as highlighted in the benefits of reducing barriers to international trade.
