what might happen in the economy if we closed the borders to trade? How does the federal budget deficit interact with an open economy/trade deficit?

Choose a good that is either made entirely in a foreign nation and imported or one that is made partially in a foreign nation and imported.Where is your good made (may be in multiple countries)? Could it be produced in the US? Why or why not? If we banned importation of this good who would benefit? Who would lose? How would you estimate the costs and benefits of the ban?Does this ban affect multiple goods or just one?How does that complicate the cost/benefit analysis?

how has the US trade deficit changed over the past three years as as tariffs have been imposed? Why?
