Why Does the U.S. Always Run a Trade Deficit?

The obvious answer to the question of why the United States runs a trade deficit is that its export sales have not kept up with its demand for imports. A less obvious answer is that the imbalance reflects a macroeconomic phenomenon. Using national accounting, one can show deficits are also due to a persistent shortfall in domestic saving that requires funds from abroad to finance domestic investment spending. Reducing the trade imbalance therefore requires both more exports relative to imports and a narrowing of the gap between saving and investment spending.
Who Pays the Tax on Imports from China?

Tariffs , of little interest for decades, are again becoming relevant given the increase in the levies charged on Chinese imports. U.S. businesses and consumers are shielded from higher tariffs to the extent that Chinese firms lower their dollar-denominated prices. However, data indicate that prices on goods from China are not falling. As a result, U.S. firms and consumers are paying the tax.
