Assume that demand for a commodity is represented by the equation P = 20 – 0.6 Qd, and supply by the equation P = 10 + 0.2 Qs, where Qd and Qs are quantity demanded and supplied, respectively, and P is the Price. Use the equilibrium condition Qs = Qd:

1. Solve the equations to determine the equilibrium price.

2. Determine the equilibrium quantity.

3. Graph the two equations to substantiate your answers and label these graphs as D1 (Demand) and S1 (Supply).

4. Using demand and supply, show what happens to the equilibrium price and quantity if eating this product causes cardiac problems.

The principles of demand and supply are fundamental in understanding how markets function and how prices are determined through interactions between consumers and producers. In this assignment, we are tasked with calculating the equilibrium price and quantity for a specific product, graphing the demand and supply equations, and analyzing the impact of health-related external factors on market equilibrium.

First, to find the equilibrium price, we set the demand equation equal to the supply equation, because at equilibrium, quantity demanded equals quantity supplied (Qd = Qs). The demand equation is P = 20 – 0.6 Qd, and the supply equation is P = 10 + 0.2 Qs. By setting Qd = Qs = Q, we obtain:

20 – 0.6 Q = 10 + 0.2 Q.

To solve for Q, we rearrange the equation:

20 – 10 = 0.2 Q + 0.6 Q,

which simplifies to:

10 = 0.8 Q.

Dividing both sides by 0.8, we find:

Q = 10 / 0.8 = 12.5.

Thus, the equilibrium quantity is Q = 12.5 units.

Next, to find the equilibrium price, substitute Q = 12.5 back into either the demand or supply equation. Using the demand equation:

P = 20 – 0.6(12.5) = 20 – 7.5 = 12.5.

Therefore, the equilibrium price is P = $12.50.

Graphing these equations involves plotting the demand and supply curves on a set of axes, with quantity on the x-axis and price on the y-axis. The demand curve D1 starts at a price of P = 20 when Q = 0, decreasing with a slope of –0.6, while the supply curve S1 starts at P = 10 when Q = 0, increasing with a slope of 0.2. The intersection point at (Q = 12.5, P = 12.5) confirms the equilibrium identified analytically. This visual representation reinforces the understanding of how the market reaches equilibrium through interactions of demand and supply.

Finally, considering the external health concern—cardiac problems caused by consuming this product—introduces a negative externality. Such health risks typically lead to a decrease in demand as consumers become more cautious or legally discouraged from consumption. Graphically, demand shifts leftward from D1 to D2, reflecting reduced quantity demanded at each price point. The new market equilibrium would occur at a lower price and quantity, indicating a market correction to the negative externality. Mathematically, suppose the new demand equation becomes P = 20 – 0.6 Qd – E, where E reflects health-related external pressure. As E increases, the entire demand curve shifts leftward, decreasing the equilibrium quantity and price accordingly. This change illustrates how external health risks can influence market outcomes, advocating for policy interventions like health warnings or taxes.

In conclusion, understanding demand and supply equations, their graphs, and the external effects on market equilibrium offers crucial insights into market dynamics and policy implications, particularly in health-related contexts. By calculating the initial equilibrium and analyzing the externality impact, we see real-world applications of economic principles that help inform policy decisions for public health.
