Final answer:
International trade affects different industries differently, based on their comparative advantages, leading to job creation in some industries and losses in others, with an overall potential rise in average wages.
Step-by-step explanation:
The effect of international trade on jobs varies significantly among different industries. This is because each industry has a different comparative advantage or disadvantage in the global market. For example, industries in which a country has a comparative advantage tend to expand, potentially increasing employment opportunities within that industry.
Conversely, industries without a comparative advantage may contract, leading to job losses in those sectors. These shifts arise due to the competitive pressures of international trade, which influence where jobs are created or lost. Additionally, international trade can contribute to a rise in the average level of wages through increased productivity, but it can also lead to disparities where some workers gain while others experience wage reductions or job losses.
