For your selected nation (ICELAND) and the United States' new/proposed rates, compare and contrast them and the impact of tax policies on business development and employment opportunities; some relationships to investigate:
-as firm's taxes increase, they reduce R & D expenditure, decrease equipment & HR investment, and increase product/service price;
-as individual's taxes increase, they, as consumers, have decreased disposable income and will adjust product/service expenditures;
-how will participation in the supply chain of product/service and employment opportunity be impacted?
