Economist Explains Math Errors in Trump Administration's Tariff Calculations

Identified Math Errors in Tariff Formula

• 🎯 Dr. Stan Veuger highlights significant math errors in the formula used by the Trump administration to calculate tariffs.
• 💡 The formula divides the trade deficit by total imports and then applies adjustment factors (epsilon and phi), but the value for phi was incorrectly chosen.
• ⚠️ The correct value for phi, representing the change in import prices when a tariff changes, should be close to one, not the 0.25 used by the administration.
• 📉 Using the incorrect number for phi results in calculated tariffs being four times higher than they should be.

Impact of Incorrect Calculations

• 📈 If the math had been done correctly, the highest tariff rates would have been below 14%, significantly lower than the nearly 50% calculated by the administration.
• 🌍 This error affects numerous trading partners, with tariffs for countries like Cambodia, Vietnam, and Laos being four times larger than they should be.
• 🗣️ Internal administration discussions reveal a lack of consensus, with officials pointing fingers at each other regarding the formula's origin, suggesting internal disagreement and potential lack of ownership.

Critiques of the Tariff Approach

• 🚫 Even with correct math, the approach of basing tariffs solely on trade deficits is criticized as bad economics.
• 🧩 Factors like comparative advantage and geographic considerations, which influence trade deficits, are ignored by this narrow approach.
• 📉 The policy's instability, with tariffs potentially changing based on negotiations, makes long-term investment in manufacturing in the US difficult.

Broader Economic and Soft Power Concerns

• 🇺🇸 Tariffs risk undermining the stability and predictability the US has offered globally, impacting its role as a stable economic force.
• ✈️ A country-by-country negotiation approach is seen as labor-intensive and less effective than consistent tariff policies.
• 🎓 The administration's policies are also seen as jeopardizing American soft power by potentially deterring international students and impacting cultural exports.
