Trade allows countries to specialize, increasing productivity and leading to better, less expensive goods and services. However, while beneficial in the aggregate, not everyone benefits from increased competition and lower prices.
Using a coffee market example, the video illustrates how opening up to international trade, where the world price is lower than the domestic price, causes the domestic price to decrease. This leads to an increase in quantity demanded by consumers.
When the world price is below the domestic price, consumers gain from trade. Consumer surplus increases for existing buyers because of lower prices and for new buyers who can now afford coffee, leading to an overall larger consumer surplus.
Conversely, domestic sellers lose from trade when the world price is lower than the domestic price. The lower price and reduced domestic sales decrease producer surplus. The difference between domestic production and consumption is covered by imports.
Despite domestic sellers losing surplus, the total economic surplus for the domestic country increases with trade. However, the gains from trade are unevenly distributed, and some individuals (like domestic producers and their employees) can be hurt.
Governments sometimes restrict trade, often using tariffs (taxes on imported goods) to protect domestic industries. Tariffs raise the world price for imported goods, leading to more domestic production but resulting in higher prices for consumers and fewer goods sold overall.
Economists generally support open international trade due to increased overall productivity and surplus. While trade benefits consumers through lower prices, it can hurt domestic businesses and workers. Tariffs, while seemingly protective, lead to inefficient resource use, higher consumer prices, and decreased economic surplus.
