Final Flashcards
Four kinds of goods
- private goods
- club goods
- common resources
- public goods
Private goods
excludabe
rival in consumption
ie: clothing, congested toll rodes
Public goods
not excludable
not rival in consumption
ie: national defence, tornado siren
Common resources
not excludable
rival in consumption
ie: fish in the ocean, Crown land, congested non-toll roads
Club goods
excludable
not rival in consumption
ie: cable tv, fire protection, uncongested toll roads
Non-excludable
Producers cannot prevent particular individuals from enjoying its benefits.
Explicit costs
Input costs that require an outlay of money by the firm.
Implicit costs
Input costs that do not require an outlay of money by the firm.
Short-run
Time period where the number of firms in the industry and the amount of land and capital employed by existing firms towards the production of a good are fixed.
Long-run
Time period were all factors of production (FOP) are variable.
Monopoly
A market where one firm dominates the market for a good that has no substitutes and where significant barriers to entry exist.
Barriers to entry
Technical, competitive or cost-related impediments to joining a market and competing against the existing firms.
Natural monopoly
Occurs in a market where the lowest cost can be achieved when only one firm sells to the market. It is typically associated with large fixed start-up costs.
Price discrimination
Occurs when different prices are charged to different consumers for the same good by the same provider.
Marginal benefits
The additional utility or satisfaction derived by an increase or a decrease in the amount of an item consumed or an activity enjoyed.
Deadweight loss
The loss of welfare, utility or benefits to market participants, typically as a result of taxes, protectionist policies or externalities.
Shut-down rule
price of its output is less than its average variable cost of production.
(If the firms total losses exceed its total fixed costs, then the firm will minimise its losses by shutting down).
Monopolistic competition
A market is monopolistically competitive if there are many firms producing differentiated products and there are no barriers to entry.
Free Rider problem
A person who receives the benefit of a good but avoids paying for it
marginal changes
small incremental adjustments to a plan of action
inflation
an increase in the overall level of prices in the economy
cost-benefit analysis
A study that compares the costs and benefits to society of providing a public good.
Tragedy of the Commons
a parable that illustrates why common resources are used more than is desirable from the standpoint of society as a whole
allocative efficeny
perfect amount of goods in market
fixed costs
costs that do not vary with the quantity of output produced
variable costs
costs that vary with the quantity of output produced
sunk cost
a cost that has already been committed and cannot be recovered
Economies of scale
when long-run average total cost falls as it increases production
Diseconomies of scale
when long-run average total cost increases as it increases production
Constant returns to scale
when it can increase production without changing long-run average total cost
Competitive market
A market in which there are many buyers and many sellers so that each has a negligible impact on the market price (price takers).
Three characteristics of economics
- There are many buyers and many sellers in the
market. - The goods offered by the various sellers are
largely the same. - Firms can freely enter or exit the market.
Exit
refers to a long-run decision to leave the market
Moral hazard
The tendency of a person who is imperfectly monitored to engage in dishonest or otherwise undesirable behaviour
