Macroeconomics in the Era of Covid-19

Background 
Read the following article in detail. Link to article: https://edition.cnn.com/2020/05/06/business/us-debt-deficit-coronavirus/index.html
Question 1
The article talks about “an invisible dog fence” reference by Maya MacGuineas, president of the Committee for a Responsible Federal Budget. What does this refer to, why is it important, and where do you think this “fence” is? Provide evidence to support your argument.
Question 2
One possible longer-run outcome once the economy improves is that we see United States bond interest rates to be low, while inflation increases. Describe how you think this situation would affect investment decisions. (Hint: Think about investment in real terms, using net present value calculations.)
Please submit assignment in word or pdf format.
A few notes:
• Please try to limit your answers to 100-150 words per question.
• Cite TWO additional articles to back up your arguments. The original CNN article or any links from that article do not count.
• Although you can talk to other students about the general ideas of the mini-project, the work must be your own.
• There are likely multiple strong answers to each question. Assignment will be graded not on the answer itself, but on having strong economic arguments to support the answer.
