Economics – The interaction of demand and supply | e-Consult

Diagram: A demand and supply diagram should be drawn. The supply curve should shift to the left, reflecting the increased cost of production due to the higher fertiliser price. Label the original equilibrium point as E1 (price P1, quantity Q1) and the new equilibrium point as E2 (price P2, quantity Q2). The leftward shift in supply will lead to a higher equilibrium price and a lower equilibrium quantity.

Explanation of Impact: The increase in fertiliser prices increases the cost of production for dairy farmers. This leads to a decrease in the supply of milk, shifting the supply curve to the left. This results in a new equilibrium with a higher price and a lower quantity traded.

Effects on Dairy Farmers: Dairy farmers face lower profits due to the lower price of milk. They may need to:

• Reduce production
• Seek alternative sources of fertiliser
• Pass on some of the increased cost to consumers (potentially reducing demand)
• Apply for government subsidies or support schemes

Effects on Consumers: Consumers face a higher price for milk, reducing their purchasing power. This could lead to a decrease in the quantity of milk consumed. Consumers may switch to cheaper alternatives, such as plant-based milk.

Other Considerations: The magnitude of the impact on farmers and consumers will depend on the elasticity of demand and supply for milk. If demand for milk is relatively inelastic, consumers will continue to purchase milk even at a higher price. If supply is relatively inelastic, the price increase will be more significant.
