The elimination of trade barriers within the European Union has greatly facilitated the movement of goods among member countries. Goods can now move freely without facing tariffs or quotas, making trade between member countries much more efficient. This has led to increased cooperation and integration among member countries, as they are now able to trade with each other more easily.
Additionally, the elimination of trade barriers has allowed member countries to specialize in producing goods in which they have a comparative advantage, leading to increased efficiency and productivity. This has resulted in member countries being able to produce all the goods they need without having to rely on trading with countries outside the EU.
However, it is important to note that larger countries within the EU may have an advantage in terms of importing and exporting goods due to their size and market power. This could potentially lead to unequal trade relationships among member countries, with larger countries having more influence in setting trade policies.
