the market for yam is in equilibrium ,show how the following events will affect the market. 1. Research has shown that eating more yam cut the risk of cardiovascular diseases. 2. there is an increase in the cost of fertilizer​

Scenario 1 ⇒ Demand for yam will increase.

If people found out that eating yams reduced the risk of them getting cardiovascular diseases, they would demand more of it so they can benefit from this reduced risk.

This will lead to a rise in price because the Demand curve will shift to the right and intersect with the Supply curve at a higher equilibrium price.

Scenario 2 ⇒ Supply of yam will decrease.

With the cost of fertilizer increasing, farmers of yam will have to incur more cost to be able to produce yams. They will therefore reduce their production levels so that they incur less cost thereby decreasing supply.

This decrease in production levels will lead to a rise in price because the supply curve will shift to the left and intersect with the Demand curve at a higher equilibrium price.

the answer is c teaching students and collaborating with teachers on instructional content.
