Tariffs: Estimating the Economic Impact of the 2025 Measures and Proposals

Tariffs are taxes imposed by a government on imported goods, typically calculated as a percentage of the import's value (known as an ad valorem tax). Governments use tariffs for various purposes, such as raising revenue, protecting domestic industries from foreign competition and influencing international trade patterns. By increasing the cost of imported products, tariffs encourage consumers to shift toward domestically produced goods, thus supporting local businesses and potentially stimulating domestic economic activity. However, the overall impact of tariffs depends critically on how much of this cost increase is passed along to domestic consumers and producers, a concept known as pass-through. Empirical research has found that the pass-through rate is generally high (often near 100 percent), meaning that the burden of tariffs typically falls on domestic consumers and firms rather than foreign exporters.
