Average Revenue Total Revenue / Quantity
Marginal Revenue Addition to total revenue from one additional sale
Short Run Time period when a firm is unable to change factors of production except for one, usually labour
Long Run Time period when all factor inputs can be changed
Minimum Efficient Scale The lowest level of output where long-run average cost (LRAC) is minimised
Economies of Scale The benefits gained through producing on a larger scale
Technical Economies Increased capacity or a technological development that results in lower long-run average cost.
Purchasing Economies Reduced unit costs due to bulk buying of inputs into a business
Managerial Economies Savings in long-run average costs due to the specialisation of management
Financial Economies The cost savings that large firms may receive when borrowing money
External Economies Falling long-run average costs that benefit all firms in an industry
Diseconomies of Scale Causes of an increase in long-run average cost beyond the point of minimum efficient scale

Dynamic Efficiency Where unit costs are lowered over time
Contestable Market A set of conditions where there is always the threat of new firms being able to enter a market
Price Discrimination Where a monopolist charges different prices for the same product in different markets
Monopolistic Competition A market structure with many firms producing a differentiated product and where there are few barriers to entry and exit
Product Differentiation Where there are minor variations in the types of products on offer
Deadweight Loss Loss to society of the firm producing where price exceeds marginal cost
Excess Capacity A consequence of firms producing above the minimum point on the average cost curve
Non-Price Competition Competition between firms on the basis of, for example, branding, customer service, location, range of products, advertising
Oligopoly A market dominated by a few large firms
Interdependent Where the actions of one firm provoke counter-action by others
Kinked Demand Indicative of price rigidity in oligopoly
Game Theory A means of modelling the behaviour of firms
Collusion Where firms tacitly or otherwise agree to not compete on prices, service provision and other matters that might adversely affect mutual well-being
Contestability The extent to which barriers to entry and exit in a market are free and costless
Sunk Costs Those costs that cannot be recovered if a firm ceases operation
"Hit and Run" Entry The way in which a firm enters a market where supernormal profits are being earned and leaves when profits return to normal
