List all the market weaknesses ✤ Imperfect Information
✤ Monopoly
✤ Public Goods
✤ Externalities
✤ Economic Instability or Recession
✤ Economic Injustice
What are the three questions we need to ask when 1. Problem: What is the source of the market breakdown?
analyzing market weaknesses? 2. Intervention: What could government do to correct the problem?
3. Evaluation: How successful is government intervention likely to be?
Unintended consequences?
, Describe imperfect information ✤ Because they do not have complete or correct information, parties make
exchanges that might be harmful.
✤ The value/cost of the good is not accurate.
✤ Both parties are not better off
what are possible government responses to imperfect ✤ Use the courts to recover damages
information? ✤ Require information labels and warnings
✤ Control production and marketing of goods
What are the challenges of government intervention in they can prevent good exchanges from happening - like the example of FDA,
relieving imperfect information? maybe lives could be lost
Describe monopoly and the problems? ✤ A monopoly can exercise significant control over prices because
it has exclusive control over production.
Inequality: Monopolist receives greater benefit from exchange
and can amass great wealth.
✤ Inefficiency: exchanges are restricted because of price
What are possible government responses to ✤ Government may regulate economically powerful firms, forcing them to
monopolies? price their products and behave like competitive firms.
✤ Example: Local utility company.
✤ Government may take action to foster competition in order to eliminate
the economic power of firms.
✤ Example: FCC decisions on exclusive cable TV deals for apartment
complexes.
What are the challenges of government intervention in ✤ Differences in interests
relieving monopolies? ✤ Businesses have powerful incentives to lobby regulatory
agencies. Individual consumers have relatively small stakes
(and thus a collective action problem).
✤ Antitrust laws
✤ Court cases can be expensive, time-consuming
What is a recession? ✤ Definition: "a significant decline in economic activity spread across the
country, lasting more than a few months ..."
✤ National Bureau of Economic Research Business Cycle Dating
Committee
✤ Great Depression lasted 43 months
✤ Previous post-WWII recessions have lasted from 6 to 16 months
(average: 10 months)
Why do recessions occur? ✤ A negative "shock" hits the economy
✤ Example: stock market correction, oil price increase, bank panic, etc.
✤ If wages and prices adjust downward quickly, full employment is preserved and
output
stabilizes
✤ But contracts, inertia, and other forces (government policies?) prevent quick
adjustment of wages and prices
✤ Output falls and resources are unemployed, including labor
✤ Recovery takes place as wages and prices adjust
