Tariffs on $200 billion of U.S. imports from China subject to earlier 10 percent levies increased to 25 percent beginning May 10, 2019, after a breakdown in trade negotiations. In this post, we consider the cost of these higher tariffs to the typical U.S. household.
One way to estimate the effect of these higher tariffs is to draw on the recent experience of the 2018 U.S. tariffs. Our recent study found that the 2018 tariffs imposed an annual cost of $419 for the typical household. This cost comprises two components: the first, an added tax burden faced by consumers, and the second, a deadweight or efficiency loss.
The magnitude of these costs depends on how a tariff affects the prices charged by foreign exporters and the U.S. demand for imported goods. Studies, including our own, have found that the tariffs that the United States imposed in 2018 have had complete passthrough into domestic prices of imports, which means that Chinese exporters did not reduce their prices. Hence, U.S. domestic prices at the border have risen one‑for-one with the tariffs levied in that year. Our study also found that a 10 percent tariff reduced import demand by 43 percent.
U.S. purchasers of imports from China must now pay the import tax in addition to the base price. Thus, if a firm (or consumer) is importing goods for $100 a unit from China, a 10 percent tariff will cause the domestic price to rise to $110 per unit. This adds a $10 cost per unit for buyers of imports, but it is not a true cost for the U.S. economy because the money is simply transferred from buyers of imports to government coffers and thus could, in principle, be rebated.
Some firms may also reorganize their supply chains in order to purchase their products from other, cheaper sources. For example, the 10 percent tariffs on Chinese imports might cause some firms to switch their sourcing of products from a Chinese firm offering goods for $100 a unit to a less efficient Vietnamese firm offering the product for $109. In this case, the cost to the importer has risen by nine dollars, but there is no offsetting tariff revenue being paid to the government. This tariff-induced shift in supply chains is therefore called a deadweight or efficiency loss.
Economic theory tells us that deadweight losses tend to rise more than proportionally as tariffs rise because importers are induced to shift to ever more expensive sources of supply as the tariffs rise. Very high tariff rates can thereby cause tariff revenue to fall as buyers of imports stop purchasing imports from a targeted country and seek out imports from (less efficient) producers in other countries.
We can see these two forces at work when we compare the estimates of the costs of the 2018 tariffs with those of the recently announced higher tariffs on $200 billion of Chinese products. As one can see in the following table, in November 2018, purchasers of imports were paying $3 billion per month in added tax costs and experiencing another $1.4 billion in deadweight losses. Thus, the total bill for U.S. importers was $4.4 billion per month. If we annualize these numbers, they amount to a cost of $52.8 billion, or $414 per household. Of this cost, $282 per household per year was flowing into government coffers as a tax increase and could theoretically be rebated. For example, U.S. government transfers to farmers to mitigate their losses from foreign retaliatory tariffs can be thought of as households receiving just this type of transfer. However, deadweight losses accounted for an additional $132 to households per annum and represent a net loss to the U.S. economy that is in excess of any tariff revenue collected by the government.
Based on these estimates, we can infer the likely cost of increasing the tariff rate from 10 percent to 25 percent on $200 billion of Chinese imports. From the table, we see that the tax portion of the cost to households actually falls, from $282 to $211 per annum, because the tariff-inclusive price for Chinese imports becomes so high that consumers start to purchase substitute goods from countries like Vietnam instead. As the U.S. economy sources more goods from countries other than China, firms are forced to pay more for similar goods, but there is no tariff revenue collected. Our results are based on estimates where imports from China can be substituted for other foreign suppliers or stopped altogether. In principle, consumers could switch expenditure to domestically produced goods, where domestic firms might be able to benefit from the lack of foreign competition, but in practice, other studies have found that other developing countries often pick up much of the slack when one of them is targeted. Nevertheless, the deadweight efficiency loss arises regardless of whether consumers switch to more expensive foreign sources or to a more expensive domestic source.
As a result of this expenditure switching, we estimate that the annualized deadweight loss increases from $132 to $620 per household, bringing the total annual cost of the new round of tariffs to the typical household to $831. In sum, according to our estimates, these higher tariffs are likely to create large economic distortions and reduce U.S. tariff revenues.
