American economist: Imposing tariffs will lead to higher prices in the US.

On the 7th local time, Trump announced that he would impose tariffs ranging from 25% to 40% on products imported from 14 countries. On the 8th, Trump also stated that a new 50% tariff would be imposed on all copper imports into the United States. Many American economists believe that the uncertainty of American tariff policies will eventually lead to price increases and harm consumer interests. Douglas Holtz-Eakin, former chief economist of the White House Council of Economic Advisers, told American media that adding a 50% tariff on copper will not reduce national security risks, but will only lead to price increases and negatively impact the economy.
