U.S. Trade Debates: The Case For and Against Trade Restrictions


Background
The 116th Congress is positioned for continuing oversight of
the Trump Administration's evolving trade policy.
Congress' role in trade policy stems from a number of
overlapping responsibilities, beginning with Article I of the
U.S. Constitution, which grants Congress the power to lay
and collect taxes, duties, imposts, and excises and to
regulate commerce with foreign nations. In some areas,
particularly in tariffs and trade negotiations, Congress has
delegated certain authorities to the President. Over the past
year, the Trump Administration has made greater use of
these authorities to impose tariffs on some U.S. imports and
advocate for what it considers to be free, fair, and
reciprocal trade. These developments have intensified
congressional interest in trade policy and analysis of the
impact of trade restrictions, including U.S. tariffs and their
effects.
Effects   of Trade Liberalization
Since World War  II (WWII), the United States has been a
driving force in removing trade barriers across the globe
and constructing an open and rules-based global trading
system through a wide range of international institutions
and agreements. The effects of these efforts on the U.S.
economy  and the mechanisms by which trade has affected
U.S. growth are difficult to quantify. This is partly due to
the challenges associated with disentangling the effects of
trade liberalization from those of other domestic and global
economic developments. Nevertheless, most economists
contend that in the aggregate the economic benefits of
reducing restrictions to trade outweigh the costs.
Reducing trade restrictions tends to lower prices and
increase the variety of goods and services and provides U.S.
firms with export opportunities. Studies show that U.S.
firms engaged in trade often achieve greater productivity
and pay higher wages and benefits to their workers. While
the net payoff is substantial, the reality is that trade
liberalization and globalization have presented both
opportunities and challenges for the United States.
Because the gains from trade tend to be more widely
dispersed than the losses, they are often not readily apparent
or well understood. Some groups argue that globalization
has not been inclusive, benefiting some more than others.
They point to job losses, stagnant wages, and rising
inequality among some groups as indicators of the negative
aspects of trade liberalization, although the causes of these
trends are highly contested.
The Trump  Administration and some Members  also
contend that while past trade negotiations and agreements
have lowered or eliminated U.S. trade restrictions, they
have failed to address effectively foreign protectionist
practices and enhance reciprocal market access for U.S.
firms and workers. In their view, some countries play by
different rules and conduct their economic and trade


policies based on priorities that differ from-and often
undermine-those  of the United States. Additionally, while
the impact of trade liberalization is multifaceted and in
some cases disruptive, the growth of global value chains-
combined  with changes related to technology, labor
productivity, consumer preferences, and broader economic
factors-have also transformed some U.S. industries.
Debates over Trade Restrictions
Arguments  for increased tariffs and other restrictions on
trade come in several forms, but most are not compelling on
economic grounds alone. Economists argue that
protectionism imposes costs on the economy as a whole
that exceed any potential benefits. These costs arise from
implementation and enforcement, higher prices, inefficient
resource allocation, and foreign retaliation. Three common
arguments for trade restrictions are evaluated below.

Trade  Destroys jobs
Some  argue that trade restrictions are needed to save jobs.
The economic  reality is that jobs are constantly being
created and replaced as some economic activities expand
and others contract, and trade-like other market forces-
contributes to this process. While some workers may
benefit from trade (e.g., those who get higher-paying jobs
when  exporters expand their production), others bear the
costs (e.g., those who are displaced because of import
competition).
During the current U.S. economic expansion, for instance,
employment  has grown by almost 20 million jobs and the
unemployment  rate has fallen from 10.0% to 4.0%, while at
the same time U.S. merchandise imports have increased
nearly 50% in nominal terms (Figure 1). In addition, the
expansion of production increasingly requires advanced
technology but relatively less labor. As a result, for many
products, labor-intensive activities like assembly have
