Microeconomics Unit 3 Exam
predicting oligopoly behavior
-cartel analysis (working together) -game theory -Use the supply and demand to model basics
cooperation possibilities for game theories
-collusion (formal and illegal) -tacit collusion (informally working together) -only possible if it is a repeated game
policy options for negative externalities
-command and control -taxes (charges) -permits
Regulatory options for natural economies
-cost plus regulation (cover cost and normal rate of return. no incentive to keep costs low) -price cap regulations (setting a price they cant go over. incentive to keep prices down. efficient as can be)
why do we expect corporations to externalize costs
-designed to maximize profits -promise to shareholders -if they don't have to pay for the cost why should they
Characterisitics of a private good

anit competitive practices
-exclusive dealing -tying sales (bundling) -predatory pricing
what makes cartels more stable
-few members with similar goals and cost structures -maintained with legal provisions -unable to differentiate their products -significant barriers to entry
natural monopoly
-high fixed costs (economies of scale) -don't want to break up natural economies because cost increase -problem with it is there isn't efficiency the lower costs wont be passes to the consumers
costs of market consolidation
-higher prices and lower quantity, deadweight loss -less variety -poor customer service -less incentive to innovate/maintain quality standards -layoffs and lower wages -small businesses are unable to compete
what does the kinked demand curve model assume
-if a firm raises it prices no one will follow them -if a firm lowers its prices it competitors will follow
potential benefits of market consolidation

How do firms differentiate

causes of market failure

monopolistic competition in the long run

public goods

common resources

characteristic of an oligopoly
