Final answer:
In the cocoa market, a drought and a new study demonstrating health benefits of cocoa will affect the price and quantity bought and sold.
Step-by-step explanation:
In the cocoa market, if countries producing cocoa experience a drought and a new study is released demonstrating the health benefits of cocoa, several factors will affect the price and quantity bought and sold. The drought will reduce the supply of cocoa, causing a shift in the supply curve to the left. This will lead to a higher equilibrium price and a lower quantity bought and sold. On the other hand, the new study demonstrating health benefits of cocoa will increase the demand for cocoa, causing a shift in the demand curve to the right. This will lead to a higher equilibrium price and a higher quantity bought and sold.
Overall, the price of cocoa will increase due to the reduced supply and increased demand, while the quantity bought and sold will depend on the magnitude of the changes in supply and demand.
