Show that the quantity of labor(X1) and capital(X2) that a firm demands decreases with a factor’s own factor price (w for labor and r for capital) and increases with the output price (P) when the production function is a Cobb-Douglas of the form q=AX1^αX2^β
As quantity of a variable input increases, explain why the point where marginal product begins to decline is reached before the point where average product begins to decline. Also explain why the point where Average product begins to decline is reached before the point where total product begins to decline.
Let the production function of a firm is given as
𝑞=(𝑥0.5 +𝑦0.5)2
Where 𝑥 and 𝑦 are inputs and 𝑤𝑥 is the price of input 𝑥 and 𝑤𝑦 is the price
of input 𝑦.
a) Assume the firm has a limited budget to spend on buying input. Find
the cost-conditional input demand function for each input.
b) Find the cost function of the firm.
With practical example. Discuss the following
1) Elasticity and income Elasticity of demand.
Ii) The relationship between price Elasticity, total revenue and marginal revenue.
III) The factors affecting price Elasticity of demand.
