The market for diamond rings is closely linked to the market for high-quality diamonds.
If a large quantity of high-quality diamonds enters the market, then the
a. supply curve for diamond rings will shift right, which will create a shortage at the
current price. Price will increase, which will decrease quantity demanded and increase
quantity supplied. The new market equilibrium will be at a higher price and higher
quantity.
b. supply curve for diamond rings will shift right, which will create a surplus at the
current price. Price will decrease, which will increase quantity demanded and decrease
quantity supplied. The new market equilibrium will be at a lower price and higher
quantity.
c. demand curve for diamond rings will shift right, which will create a shortage at the
current price. Price will increase, which will decrease quantity demanded and increase
quantity supplied. The new market equilibrium will be at a higher price and higher
quantity.
d. demand curve for diamond rings will shift right, which will create a surplus at the
current price. Price will decrease, which will increase quantity demanded and decrease
quantity supplied. The new market equilibrium will be at a lower price and higher
quantity.
