Price Elasticity of Demand
The responsiveness of the quantity demanded to a change in price, measured by dividing the percentage change in the quantity demanded of a product by the percentage change in the product's price.
The demand for a product is highly responsive to price changes. The range of a demand curve where elasticities of demand are greater than 1.0.

a given change in price causes a proportional change in quantity demanded. The point of any demand curve where revenue is maximised.
Perfectly elastic demand
Any increase in price results in all demand being eliminated.
Perfectly inelastic demand
the case where the quantity demanded is completely unresponsive to price, and the price elasticity of demand equals zero.
Cross (Price) Elasticity of Demand
a measure of how much the quantity demanded of one good responds to a change in the price of another good, computed as the percentage change in quantity demanded of the first good divided by the percentage change in the price of the second good.

a good that consumers demand less of when their incomes increase. Occurs when yED is a negative value.
Price Elasticity of Supply
a measure of how much the quantity supplied of a good responds to a change in the price of that good, computed as the percentage change in quantity supplied divided by the percentage change in price
a fixed amount that is imposed upon a product by the government; it has the effect of shifting the supply curve vertically upwards by the amount of the tax.

A tax on a good that is often meant to limit consumption of that good.
the actual division of the burden of a tax between buyers and sellers in a market

a maximum price that can be legally charged for a good or service: set below equilibrium
a legal minimum on the price at which a good can be sold: set above equilibrium
the amount a buyer is willing to pay for a good minus the amount the buyer actually pays for it. It is seen as excess utility for the consumer.
the amount a seller is paid for a good minus the seller's cost of providing it. It is viewed as excess satisfaction for the producer.

Marginal Social Cost
the true cost borne by society when the production of a good or service is increased by one unit
a good or service considered as beneficial for people and that would be under provided by the market and so under consumed
a good or service considered to be harmful for people who consume them and society as a whole. If left to the market forces or private enterprise, they would be over-produced and thus over consumed

a period of time sufficiently short that at least one of the firm's factors of production cannot be varied
A period of sufficient time to alter all factors of production used in the productive process - all inputs can be changed.
all the goods and services produced by a business during a given period of time with a given amount of input
Law of Diminishing Marginal Returns
As more of a variable resource is added to a given amount of a fixed resource, marginal product eventually declines and could become negative
The total opportunity costs of production to a firm, including the opportunity cost of entrepreneurship.
Costs that do not vary with the quantity of output produced
Costs that vary directly with the level of production
Total Costs divided by quantity. ATC = TC/Q
Increasing returns to scale
When long-run average total cost declines as output increases. Economies of scale outweigh diseconomies of scale
Economies of Scale
factors that cause a producer's average cost per unit to fall as output rises in the long run
Diseconomies of Scale
factors that cause a producer's average cost per unit to rise as output rises in the long run
the amount paid by buyers and received by sellers of a good, computed as the price of the good times the quantity sold
Total revenue minus total cost, including both explicit and implicit costs - accounting profit minus the opportunity costs.
the payment made by a firm to obtain and retain entrepreneurial ability; the minimum income entrepreneurial ability must receive to induce it to perform entrepreneurial functions for a firm
Refers to a firm earning as much sales revenue as possible while, at the same time, keeping costs to a minimum. Profit maximisation is the most common goal for a firm. Occurs at the quantity of output where MR=MC
An alternative goal of some firms: to produce the output level yielding the highest value of sales (MR=0)
An alternative goal of some firms: to expand output as quickly as possible
Choosing an option that is acceptable, although not necessarily the best or perfect.
a market structure in which a large number of firms all produce the same product and no single seller controls supply or price and barriers to entry are low
products that have income elasticity between 0 and 1. When consumer income grows, quantity demanded rises by less than the rise in income.
goods that have income elasticities greater than 1. when consumer income grows, quantity demanded of luxury goods rises more than the rise in income

the extra cost of producing one more unit of output
the sum of the fixed and variable costs for any given level of production
the production of a good in the least costly way: occurs at ATC minimum.
Decreasing returns to scale
when long-run average total cost increases as output increases: diseconomies of scale outweigh economies of scale
Constant returns to scale
the property whereby long-run average total cost stays the same as the quantity of output changes
Revenue per unit produced. It is calculated by dividing TR by the output. NOTE: This is always equals Price if there is no price discrimination.
the additional income from selling one more unit of a good; sometimes equal to price
a short-run decision not to produce anything during a specific period of time because of current market conditions. This would minimize losses for the firm if AVC > AR at Qpm. The firm would only be losing it's fixed costs.
Operate at a loss
a short-run decision to continue operating in spite of losses. Losses would be minimized with this decision if AR>AVC at Qpm. In other words, the revenue would be paying for all of the variable costs and some portion of the fixed costs.
