A survey conducted by American Express in 2015, found that 23% of American adults "hide bills in a secret location at home." a. When people keep their currency for the purpose of saving it, money performs the following function: Money held within your home is easy to spend, so it functions as a medium of exchange. People are holding money for future use, so the money is functioning as a store of value. Since the hidden money is not reflected on tax returns, the money will function as a separate unit of account. A person's money is easier to count this way, so the money is a unit of account. b. Which of the following should be a concern to individuals who keep large amounts of currency hidden in their home:

This saving can be used in future for any purpose. So, they are storing the purchasing power for future. When the money is stored as the purchasing power for the future, it serves as store of value. So, People are holding money for future use, so the money is functioning as a store of value.
