The headlines regarding Trump's proposed tariffs and their inflationary consequences are undoubtedly worrying, but will they prove correct?

Instead of taking the "experts" at their word, let's consider how tariffs may affect the prices of all goods and services, not just the items subject to tariffs. Furthermore, it's worth discussing how tariffs could impact the economy, as economic activity greatly influences inflation. Lastly, we lean on historical precedence, capitalism, and the dollar to further evaluate how tariffs might impact inflation and economic growth.

Higher prices & the substitution effect

Price changes of a good or service are primarily a function of supply and/or demand variations. However, price indexes – the basis for how economists measure inflation – are constructed on the prices of a basket of goods and services. The goods and services within the basket are weighted by the consumption of said items.

Considering the difference between the price of one good and the inflation index for an economy, let's think about how consumers react to higher prices.

If the price of an imported good increases due to a tariff, and the company selling the good commensurately increases the price, consumers respond in three ways.

  • Some consumers will decide not to pay the higher price and purchase a substitute good.
  • Others will decide not to pay the higher price or buy competing goods and save their money.
  • Another group of consumers will pay the higher price, leaving them with less money to buy other goods.
