Economics Homework Help

I’m working on a macro economics discussion question and need an explanation and answer to help me learn.

Chapter 12 discusses the resource markets, labor, and productivity. Can you discuss how productivity gains are the source of higher wages? Do you think that the lack of those might have been a contributor to the Great Resignation?

Chapter 16 is about international trade and tariffs. Suppose that a huge tariff was imposed on steel imported into the US. How would that affect the cost of the cars and subsequently employment in the US auto industry?
