Verified step by step guidance

1. Step 1: Understand the definitions of tariffs and sanctions. A tariff is a tax imposed on imported goods, while sanctions are penalties or restrictions imposed on countries or entities to influence their behavior.
2. Step 2: Analyze the primary purpose of tariffs. While tariffs can generate government revenue and protect domestic industries, they are often used strategically to influence foreign producers or governments by making their goods more expensive.
3. Step 3: Analyze the primary purpose of sanctions. Sanctions are typically used as a political or economic tool to pressure foreign governments or entities to change certain behaviors or policies.
4. Step 4: Compare the objectives of tariffs and sanctions. Both can serve as instruments to influence the behavior of foreign governments or producers, rather than solely focusing on consumer surplus or correcting externalities.
5. Step 5: Conclude that the similarity between tariffs and sanctions lies in their use as tools to influence foreign behavior, rather than primarily aiming to increase domestic consumer surplus, eliminate externalities, or reduce marginal social costs.
