Chp 14 Flashcards
Many buyers/sellers, goods are identical, free entry and exit, no barriers to entry
Perfectly competitive markets
True or False: The actiona of a single buyer/seller have a negligible impact on the marlet price of a good/service. No single firm is powerful enough to control price.
True
Individuals who take the given market price are?
Price takers
Total Revenue (Linear)
Price times Quantity sold (P x Q);
Profit
Total Revenue minus Total Costs (TR - TC)
True or False: Total Costs must be higher than Total Revenue, otherwise losses occur
True
How much revenue a firm gains from each typical unit sold?
Average Revenue ( TR / Q )
Marginal Revenue
The change in revenue from an additional unit sold
The change in Total Revenue / The change in Quantity
True or False: Marginal Revenue equals Price in a perfectly competitive market ( MR = P )
True
True or False: Price = Average Revenue = Marginal Revenue
True
As long as Marginal Revenue is greater than Marginal Costs? ( MR > MC )
A firm should keep making that Quantity of product
If Marginal Revenue is less than Marginal Cost ( MR < MC ),
A firm should produce less product
When a firm maximizes profit, it sells Quantity at the point where
Marginal Revenue = Marginal Costs
True or False: In a perfectly competitive market, a firm produces where Price = Marginal Revenue = Marginal Cost ( P = MR = MC )
True
True or False: A firm’s supply curve is its Marginal Cost (MC) curve
True
Where a firm temporarily stops producing because of marlet conditions
Shutdown
Shutdown occurs where
Total Revenue < Total Variable Costs (TR < TVC) or Price < Average Variable Costs (P < AVC)
Sunk costs
Costs that have already been spent and cannot be recovered
Firm’s SR supply curve
The portion of the Marginal Cost (MC) curve that is above the minimum Average Variable Cost (AVC)
Shutdown Price
Where Price equals minimum Average Variable Cost (P = AVC)
Shutdown Price
P = AVC
A competitive firm’s demand curve is perfectly (elastic/inelastic)
Elastic
In a perfectly competitive market, for a firm;
Price equals Average Revenue equals Mariginal Revenue equals Demand
(P = AR = MR = D)
When Price > Average Total Cost,
Positive economic profit
