FalseFalseFalseFalseFalseFalseThe price of money is the interest rate.Savers should weigh the expected benefits and costs of savings.Inflation influences the value of money over time.In such a case, inflation exceeds the return on savings, making it unwise to save.The rule of 72 provides a method for calculating how long it takes for savings to double.When people save, they make more money available in the loanable funds market. This means more dollars will be available for borrowing and lending.There may be ties when saving is not worth the sacrifice. In periods of high inflation, for example, it is expensive to save. Economics of SeinfeldThis illustrates that when savers save, their assets don't sit idle; they are immediately channeled to some productive investment most often by the banking system or another intermediary (such as the blood bank in this example), but sometimes through direct transfer (such is the case with direct purchase of stocks and bonds, and in this example, the direct transfer of Kramer's blood to Jerry).The Blood
In this episode, Kramer is donating blood and saving it in a blood bank for future use. He becomes dissatisfied with high fees at the blood bank, and decides to keep it at home instead. In the meantime, Jerry nicks his jugular with an Exacto knife and needs blood. He awakens in the hospital with three pints of Kramer's blood in him.When deciding whether to save or consume, people ought to weigh the expected costs against expected benefits. It is important to consider real numbers adjusted for price-level changes in making such decisions.

Activity 1 Part 3What is the loanable funds market?The loanable funds market is the market that brings together the people who want to supply funds (savers) and the people who want to demand funds (borrowers).How does increasing savings cause interest rates to decrease?Adding money into the loanable funds market increases the supply of savings dollars. This shifts the supply curve for dollars to the right, causing the price (interest rates) to fall.How does reducing savings cause interest rates to increase?Reducing the amount of money in the loanable funds market decreases the supply of savings dollars and shifts the supply curve for dollars to the left, causing the price (interest rate) to increase.
