Governments intervene in trade for economic and noneconomic reasons. Economically, they aim to protect domestic industries and jobs through measures like tariffs and quotas. Noneconomically, reasons include national security, cultural preservation, and political influence. However, intervention can backfire and harm consumers through higher prices. It may also lead to retaliation. While companies initially seek government protection, they must also innovate and adjust to global competition over time. Measures include relocating production, focusing on market niches, and internal efficiency gains. Overall, the effects of subsidies, quotas and other policies on trade are complex, with both benefits and unintended consequences requiring consideration.
