Market Economics
Current Issues - LHS
Supply and Demand• Supply
– Reflects the amount of a product available to be purchased at a particular place
– UPWARD slope• Higher the price, the more
quantity of a product is available
• Lower the price, the less quantity of a product is available
– Suppliers produce more when prices are high b/c they make more money selling products at the higher price
Supply Curve
Supply and Demand• Demand– Reflects the desire for
a product at a particular price
– DOWNWARD slope• The higher the price the
less demand for a product
• The lower the price, the more demand for a product
– The higher the price, the lower the quantity someone buys
Demand Curve
Supply and Demand• Finding “equilibrium”
between supply and demand– Equilibrium = where
supply, demand curves intersect
– Means that the amount of goods being supplied is exactly the same as the amount of goods being demanded
– When this happens, everyone is happy! (unfortunately, it’s only theoretical)
Let’s Practice!
• What happens to demand if price goes UP?
• What happens to supply if price goes UP?
• What happens to demand if price goes DOWN?
• What happens to supply if price goes DOWN?
The Business Cycle
• Refers to shifts in the economy over time
• Measured by the growth rate of the Gross Domestic Product– GDP = total market
value of goods and services produced in a year
– Used as a common comparison point between countries
The Business Cycle• Expansion (increase in
production and prices)• Crisis (stock exchange
crash, b/k)• Recession (drops in
price, output)• Recovery (stocks
recover b/c price, incomes fall)
• Since WWII, business cycle has not been as extreme (gov’t use of fiscal, monetary policy to avoid worst effects)
Government Regulation & the Economy
• Two categories– Economic regulations
seek to control prices• Prevent monopolies
from gouging consumers
• Stabilize agricultural prices
– Anti-trust law strengthens market forces to avoid direct regulation• Prohibit practices that
lessen competition• Prevent mergers that
would limit competition
Government Regulation of the Economy
• Other bases of government regulation– Protecting public’s
health and safety– Maintain clean and
healthy environment– Preventing businesses
from failing• Bailouts, direct purchase
of business by government
• Nationalization of businesses: appropriate or not?
Deregulation
• Conservatives usually support fewer regulations on business
• They argue that regulations:– Interfere with free
enterprise– Increase costs of doing
business– Contribute to inflation
• Is deregulation appropriate or not?
