While the Sustainable Development Goals (SDGs) do not explicitly mention trade, freer trade does support at least two of them: SDG 8 (Promote inclusive and sustainable economic growth, employment, and decent work for all) and SDG 12 (Ensure sustainable consumption and production patterns) are possible through the benefits of the movement of goods and services globally. Dating back to the work of Adam Smith and David Ricardo, evidence suggests that trade is beneficial and that different types of countries can gain from trade. The gains come from efficient production and expansion of consumption opportunities.
