Business Economics Concepts and Applications

This business economics assignment explores various economic concepts. It analyzes the impact of price fluctuations on solar panels using supply and demand curves. Additionally, it examines the effect of a decrease in electricity prices on the solar panel market and an increase in solar panel producers. Finally, the assignment calculates the price elasticity of demand for CDs and discusses its implications for Universal Music's pricing strategy.

a)
Figure 1: Price of solar panel is above the equilibrium price
Market equilibrium is obtained when demand and supply curve cuts each other (Fine 2016). dd
and ss in the above figure represents the respective demand and supply curve in the market. P*
is Equilibrium price and Q* is the equilibrium quantity. Suppose now, price is above the
equilibrium price say at P1. At this price market supply exceed the market demand creating an
excess supply of the amount ab. For the excess quantity to be sold in the market price has to be
reduced and reaches to the equilibrium price.

b)
Figure 2: Effect of a fall in price of electricity
The market for solar panel and electricity are substitutes. For, substitute goods a decrease
in the price of a good leads to an increase in own demand while reduces the demand for the
substitute good (Baumol and Blinder 2015). When price of electricity is decreased by 50% , then
people will use more electricity. Given price of solar panel, it seems costlier for consumers and
hence, they reduces the use of solar panel. As a result, the market demand curve of solar panel
shifts leftward. Both equilibrium price and quantity reduces in this situation. the new price is P1
and the new equilibrium quantity is Q1.

c)
Figure 3: Increase in the number of solar panel producer
When number of solar pane producers increases, the supply in the solar panel will
increases. The supply curve in the solar planer market will shift to the right. The new
equilibrium is obtained at the intersection of the new supply curve and old demand curve
(Mahanty 2014). From the figure, it is seen the new equilibrium price is P1 and quantity is Q1. In
the new equilibrium price is reduced whereas the quantity supplied increases.
Answer 5
a) Price elasticity of demand for CD

5BUSINESS ECONOMICS
Price elastcity of demand= Percentage change ∈demand
Percentage chnge∈price
The estimated change in demand when average price of CD decreases from $21 to $21 is
40 percent
percentage change ∈price= 21−15
21 ∗100=28.57
Price elasticity of demand= 40
28.57 =1.40
b) Elasticity plays an important role in deciding the benefits that the firm is going to obtain
from price change. Revenue is price multiplied by quantity sold. Buyers are able to
change their demand to a greater proportion than price then, then demand is said to be
elastic (Moulin 2014 ). In this case, price reduction is beneficial for the firms, as they will
be benefitted more from the increased sale than loss from price reduction. The estimated
elasticity measure is 1.40. Since, the demand is elastic in nature a price cur is advisable
for Universal Music CD.
