Chapter 02 – Understanding Economics and How It Affects Business
220. A rare and scarce earth metal known as Neodymium is used in many consumer and
military products including smart-phones, smart-bombs, laptop computer monitors, and
electric/hybrid cars. In one year’s time, the price of Neodymium has gone from $19/lb. to
$129/lb. Under these circumstances and the fact that at least 1 kilogram is used in each
electric car that is assembled, a graph of the supply and demand for this product would
show:
A. The current price of Neodymium to be below the equilibrium price for this rare earth
metal.
B. The price of Neodymium to be above the equilibrium price for this rare earth metal.
C. The price of Neodymium to reflect the adjustment of quantity demanded and quantity
supplied.
D. Consumer demand for a product such as electric cars to shift to the right indicating the
desire to purchase the rare earth metal at any price.
Feedback: When there is a shortage of a natural resource, it becomes scarce. The continued
demand for the product will cause the price to increase, at least temporarily, above the
equilibrium point where the quantity supplied and the quantity demanded constitute the
market price: the price that sellers are willing to sell the product for, and buyers are willing to
buy.
221. The price of iPhones™ is falling. In a free-market economic system where everything
else is equal, the most likely explanation is:
A. Suppliers are not producing enough product.
B. Sellers cannot keep up with market demand.
C. The government determined that the product was not worth the price tag that the
producer was asking.
D. The product has competition at the equilibrium price.
Feedback: If producers (sellers) are able to supply the amount of iPhones™ needed at the
market price, but in the short-run, the price is falling, everything else being equal, the likely
problem is added competition in the marketplace.
