Markets In Action Flashcards
Main functions of the price mechanism
Allocation, Rationing, Signalling, Incentives
Allocation
Allocating scarce resources away from markets exhibiting excess supply and into markets where there is excess demand
Rationing
Prices serve to ration scarce resources when market demand outstrips supply
Signalling
Prices adjust and provide information to buyers and sellers. Prices which cause excess demand can act as a signal to firms to raise prices for example
Interest rates
The cost of borrowing money
Elasticity
The responsiveness of something to changes in another component
Nominal Income
Your income without taking into account the rate of inflation
Real Income
Your income while taking into account the rate of inflation
Perfect competition
- Homogeneous products
- Price takers
- Perfect knowledge
- Many firms
- No barriers
- AR=MR=D
Imperfect competition (Monopoly)
- Differentiated products
- Price makers
- Barriers to enter and exit
- One firm
- Imperfect knowledge
- AR=D, MR different
Market Conduct
How markets compete and whether firms work in isolation or have competition
Market performance
Whether the market satisfices or profit maximises along with market efficiency
Reasons for increase market competition
Price and non-price competition which can drive down prices, improve quality of goods. Firms will cut costs leading to greater efficiencies.
Creation of differentiated goods which can give consumers greater variety.
Monopolistic competition
A form of imperfect competition. It’s like the perfect competition but more realistic. Many buyers and sellers, slightly differentiated goods, firms are price makers, low barriers to entry and exit, good info, non-price competition, profit maximisers
Social efficiency
The optimal distribution of resources in society taking into consideration all the internal and external costs and benefits
Oligopoly competition
- Few firms dominate the market (4-6 hold 60% ms)
- Differentiated goods
- High barriers to entry/exit
- Interdependence
- Non-price competition
- Fight for market share over profit maximising
Contestable markets
Always changing and driven by the fear of competitors and threat of new entry. Almost all markets are contestable to some degree. An entrant has access to all production techniques with no barriers to entry/exit and no sunk costs.
Hit and run entry
When businesses enter an industry to take advantage of temporarily high (supernormal) market profits then leave after taking those profits
Sunk costs
Costs that cannot be recovered if a business decides to leave an industry. The existence of sunk costs makes a market less contestable
Creative destruction
Evolution of innovations and technologies. When newer innovations destroy older economic structures while simultaneously creating new ones. For example the invention of the automobile caused the fall of the horse and carriage market
Price fixing in a cartel
A cartel is a group of firms colluding to maintain high prices. In a competitive market demand is equal to supply but in a cartel they will charge the profit maximising price and will not set prices lower, they restrict output and increase price. Cheating in a cartel can destroy the cartel so they sanction the cheater and rebuild. Main aims are profit maximising and price fixing which is achieved by quarters based on each firms contributions
Negatives of a cartel
Cartels allow inefficient firms to stay in business rather than cutting costs or going out of business, while other more efficient members of the cartel enjoy abnormal profits. Cartels portray the disadvantages of monopoly by protecting inefficient firms and enabling firms to enjoy an easy life protected from competition along with unnecessarily high prices for consumers
Divorce of ownership from control
A situation where the owners (shareholders) and those who control the firm (managers) are different groups with different objectives
Long run monopolistic competition
No allocative efficiency as MC is lower than price, consumers being exploited. No productive efficiency as not producing at lowest point of AC. No dynamic efficiency as no long run sp so not enough profit to reinvest
