other antitrust issues

Restrictive Practices: -price fixing, market sharing, predatory pricing -resale price maintenance -exclusive dealing -tying sales/bundling Mere Bigness is not a crime

anti trust laws:

Series of laws that tried to protect consumers against monopolization and limited competition

What were the first and second anti trust laws?

The Sherman Act (1890). It prevented monopolization and conspiracy in restraint of trade . Clayton Act (1914). Interlocking directorates, allowed gov. to oversee mergers, triple damages

mere bigness is not a crime

a business that is huge and dominates its market; as long as it play fair, theres not an antitrust problem

exclusive dealing

a firm will agree to sell a good to a retailer only if the retailer agrees only to buy from the firm. this reduces competition because the retailer can't go out and find better prices

how does government oversight the market place

by anti trust laws and through regulation of business

economics issues

economics issues: -efficiency from economies of scale -decrease in market competition *the more concentrated it is, it is less competitive it is

market sharing

firms agree not to compete against each other

substantial economies of scale occur when

fixed costs are upfront and the rest of the marginal costs are lower. this results in the AVFC to be lower. inevitably, these firms can become monopolies. 1. the industry is a monopoly 2. these natural monopoly situations often occur with goods and services that we tend to think are viable to our well being. the govt has declared certain natural monopolies to be public utilities and if the firm is said to be a public utility then the govt. has the right to regulate that firm. by regulating it means; govt. has approval over the prices that it will charge but the regulation inevitably goes further than that...

mergers and acquisitions

mergers and acquisitions:

pre-notification

pre-notification: -if two companies want to merge they have to notify the govt. and say "we want to merge". The govt. is then given 90 days to study this proposal and if they think the merger will not be a good thing, then they get to challenge it.

resale price maintenance

sells goods to a retailer and then tells the retailer "you need to sell this good for this price". it limits competition to the harm of consumers.

if the average total cost curve of a firm is constantly falling then

the marginal cost curve MUST be bellow it. it must be that the cost of producing an additional unit goes down.

competition is good for consumers true or false?

true

large scale production can reduce average cost of production through economies of scale, true or false?

true

markets in the real world are rarely perfectly competitive, true or false?

true

Regulatory Lag

when a company requests a rate increase, the hearing process of studying the issue and hearing the decision can drag on for a long time

predatory pricing

when a large established firm artificially lowers its price if a new firm enters the market. By pushing the price really low, the new firm will not be able to establish its position in the market. Even though the big firm will lose money for a little while, they will kick the small firm out.
