Antitrust
• U.S. Law
– Sherman Act (1890)
– Clayton Act (1914)
– Various regulatory acts (Federal Trade Commission Act of 1914,
Telecommunications Act)
• Economic Rationale
– Monopolist will produce output to the point where MR=MC.
– When demand is downward sloping, the MR schedule is always
below the demand curve, so that at any output, consumer
willingness to pay for an additional unit exceeds the MR that
producing the unit gives the monopolist
Antitrust
• At the monopoly output, the social marginal value (i.e. willingness to
pay for an additional unit) exceeds MC, so increased output would
improve social welfare.
• Social marginal benefit is maximized when p= MC, i.e. at the
competitive equilibrium.
Antitrust
– This result holds more generally in so-called general equilibrium
models, where reduced competition results in an equilibrium
allocation of all goods and services which is not socially optimal.
• Natural Monopoly
– As we saw in our discussion of the dominant firm model, a
declining average cost structure (which makes being large
advantageous) coupled with network externalities can lead
naturally to the emergence of a dominant firm.
– This market configuration is generally socially optimal since the
dominant firm can best supply society with the products it wants
(the externality effect) at the cheapest possible cost (via the
declining average cost).
Antitrust
• Antitrust issues with natural monopoly
– Under-provision of product, over-pricing
– Anti-competitive business practices
• Bundling of competitive products with monopolized ones
• Exploiting common carrier status to vertically integrate a market
• Collusive behavior with rival firms (cartel formation)
Antitrust
• Price Regulation
– Public utility review and approval authority over prices and extent
of service
Antitrust
• Regulating Business Practices
– Require government approval of changes in business practices
– Formalize common carrier status of monopoly
• Legal Remedies
– Civil suits
– Divestiture
• Social Consequences of Antitrust Actions
– Positive
• Restored competitiveness of the market
• Enhanced innovation
– Negative
• Potential loss of scale/scope economies associated with natural
monopoly
Information Policy
• Copyright
– Balancing social benefit against the need for incentives
– Role of technology in undermining this balance
– Public Goods
• Non-excludable
– Impossible to prevent someone from consuming the good once it has
been provided
• Non-rival
– Social marginal cost of consuming one additional unit of the good is zero
• Public Provision
Information Policy
• Taxation
– For provision of public goods and services
• Benefit Principle
– As an economic policy lever
• Capital formation issues
– Organizational capital
• Privacy
– New Applications
• Digital cash
• Electronic signatures
• Electronic contracts
– Regulatory Issues
• Protection of personal information
– Credit histories and ratings
– Health status
– Personal history (past criminal records, employment history)
Information Policy
• An economic rock and a hard place
– Adverse selection revisited: Health Insurance
– Two risk classes, healthy people and sick people
– Monopoly insurance company (separating equilibrium)
» Policies targeted to healthy generate incentives for sick to mimic
healthy
» If costs of covering illness are sufficiently high, insurance company
loses money
» Only policies targeted to sick make a profit
» Healthy don’t buy insurance
» Since only healthy people don’t have insurance, entrants can make
a profit providing insurance targeted to healthy.

» Market fails
• Protection from unwanted marketing
– Spam
– Unwanted advertising
– Price discrimination
Information Policy
• Globalization
– Comparative Advantage and Free Trade
Information Policy
– Business Cycles
– Role of financial markets
• Free movement of capital
• Contagion
– Similarity to bank runs
– Self-fulfilling prophecies
– Labor Markets and Migration
• Economic migrations are demand-pull
• Political migrations
• Wage equalization
