Answer: c. 1 and 3
Explanation:
1. Even though Investors and Savers forego their immediate consumption for future consumption, it is generally assumed that both groups actually prefer immediate consumption to deferred consumption.
This is why they are offered a rate of return that compensates them enough to convince them to take deferred consumption over current consumption.
3. When inflation rises, it erodes the value of money such that people are able to buy less goods using the same amount of money as they were able to before.
If you therefore receive a payment of $100 and inflation is 5%, then 5% of the value of that $100 has been eroded which is $5. This means you're only able to buy $95 worth of goods and services.
