level questions: Long Run Average Cost

QuestionAnswer
In the Long Run, what can happen their Short Run Average Cost? (SRAC: This is just AC)-Since all Factors of Production are Variable, Firms can have the potential to boost Productivity. -So, SRAC can shift Downwards and Right. South East. -SRAC will however have an AC where it can’t go lower, which can be the most Productive Efficient Point.
What is the Firm’s Long Run Average Cost?-LRAC shows off the Minimum AC at each level of Production. -It follows the lowest Point of each SRAC. -LRAC can show the Point where the Firm’s Maximum Productive Efficient point is. Just how SRAC is a U Shape, an LRAC is too.
How is the Shape of the LRAC determined?-Average Costs will Fall, when Output rises. This occurs when a Firm has Internal Economics of Scale. -Average Costs Rise, when output rises as well. This occurs when Firms has Internal Diseconomies of Scale. -Firms can experience both Internal Economies/Diseconomies at same Output - whichever one has the Greatest effect matters here.
What is 1. External Economies of Scale 2. External Diseconomies of Scale1. This makes the LRAS fall Downwards - AC falls at ALL output levels (Technology breakthrough) 2. Forces the LRAS upwards - AC rises at ALL Output levels (Fuel Duty)
