Writing Assignment
Section 1:
1. Equilibrium Price
Qs = Qd
QUANTITY SUPPLIED
P = 2 + 0.2Qs
P - 2 = 0.2Qs
(P - 2)/0.2 = Qs
QUANTITY DEMAND
P = 10 - 0.2Qd
0.2Qd = 10 - P
Qd = (10 - P)/0.2
(P - 2)/0.2 = (10 - P)/0.2
P - 2 = 10 - P
P + P = 10 + 2
2P = 12
P = 6
2. Equilibrium quantity
6 = 2 + 0.2Qs
6 - 2 = 0.2Qs
4 = 0.2Qs
4/0.2 = Qs
Qs = 20
6 = 10 - 0.2Qd
0.2Qd = 10 - 6
0.2Qd = 4
Qd = 4/0.2
Qd = 20 3.
4.
A)
B) An increase in demand will create a shortage, which increases the equilibrium price and equilibrium quantity.
C) This product is a NORMAL good
Section 2:
The business cycle describes the growths and declines that an economy will experience over a length of time. Businesses go through a pattern of ups and downs in their activity level similar to a roller coaster. The value of the activity level is measured from peak to peak by gross domestic product (or GDP) and will fluctuate over a period of time. The five stages of the business cycle are growth (expansion), peak, recession (contraction), trough and recovery. Although long term patterns are predictable their frequency, magnitude, and duration are irregular.
Part A)
The business cycle is characterized by four main phases. During economic growth or expansion there is a “Boom” period of rapid economic growth, prosperity.

The energy is high and unemployment is low as economy creates new jobs. An economic boom occurs when real GDP grows faster than the trend rate of economic growth. An example of this is the housing market boom earlier this century.
