Answer: Drop, rise
Step-by-step explanation:
When the market price of the coffee drops the owner of the coffee field will not receive the profit of selling the coffee and he or she will reduce the wages of the coffee labors. On the other hand if the coffee prices in the market increase the owner will also gain profit and will also increase the wages of the labor. So, the wages of the labor is dependent upon the profit or loss the owner receives on selling the coffee yield.
