What is the supply curve of a firm in the long run?

The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.

A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?

How does the imposition of a unit tax affect the supply curve of a firm?

What is the relation between market price and average revenue of a price-taking firm?

How does an increase in the number of firms in a market affect the market supply curve?

How does an increase in the price of an input affect the supply curve of a firm?

How does technological progress affect the supply curve of a firm?

Will a profit-maximising firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.

Will a profit-maximising firm in a competitive market produce a positive level of output in the short run if the market price is less than the minimum of AVC? Give an explanation.

Explain the concept of a production function

Find out the maximum possible output for a firm with zero units of L and 10 units of K when its production function is Q = 5L = 2K. 

How is the equilibrium number of firms determined in a market where entry and exit is permitted?

How is the wage rate determined in a perfectly competitive labor market?

If duo poly behavior is one that is described by Cornet, the market demand curve is given by the equation q = 200 - 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price.
