Briefly explain the concept of the cost function.
The functional relationship between the cost of production and the output is called the cost function. It is expressed as
C = f ( Qx )
Where,
C = cost of production
Qx =units of output x produced
In other words, the output-cost relationship for a firm is depicted by the cost function. The cost function depicts the least cost combination of inputs associated with different output levels.
What is the total product of input?
When does a production function satisfy decreasing returns to scale?
Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve?
Explain the relationship between the marginal products and the total product of an input.
What is the law of diminishing marginal product?
The following table gives the total product schedule of labour. Find the corresponding average product and marginal product schedules of labour.
Why is the short-run marginal cost curve 'U'-shaped?
What do the long-run marginal cost and the average cost curves look like?

When do we say that there is an excess demand for a commodity in the market?
What do you mean by the production possibilities of an economy?
How are the total revenue of a firm, market price, and the quantity sold by the firm related to each other?
What is budget line?
How do the equilibrium price and the quantity of a commodity change when the price of input used in its production changes?
The following table shows the total cost schedule of a competitive firm. It is given that the price of the good is Rs 10. Calculate the profit at each output level. Find the profit maximising level of output.

5 15 22 27 31 38 49 63 81 101 123 |
