Answer to Question #299634 in Microeconomics for MAKGOROMETSA

Question

2.1 Consider the production function: Y=2X + 16X2- 0.4X3 a) Derive marginal value product (VMP) and average value product (AVP) equations. [04] b) At what levels of X do the TPP reach its maximum? [03] c) At what level of X does stage two (II) begin or stage one (I) end? [04] d) Find and interpret elasticity of production (EP) when X = 1. [02] 2.2 Market structures are referred as the competitive environment in which the buyers and sellers of the product operate. A market consists of all the actual and potential buyers and sellers of a particular product. Discuss thoroughly oligopolistic and perfect competitive market structure and give examples of each form of the market structure. [08] 2.3 Differentiate between product market and labour market (Use diagrams that explain the interactions in the markets). [04

Answer 1

$Y=2X+16X^{2}-0.4X^{3}$

$VMP=\frac{dy}{dx}=2+32X-1.2X^{2}$

$AVP=\frac{Y}{X}=2+16X-0.4X^{2}$

TPP is maximum when VMP is 0

$2+32X-1.6X^{2}=0$

Solving using quadratic formula

$X=\frac{-b+-√(b^{2}-4ac)}{2a}$

$=\frac{-32+-√(32^{2}-4×-1.2×2)}{2×-1.2}$

$X=26.7$

Stage 2 begins when$VMP=AVP$

$2-32X-1.2X^{2}=2+16X-0.4X^{2}$

$=0-48X-0.8X^{2}$

Solving for X using quadratic formula

$X=\frac{48+-√(48^{2}-4×0.8×0)}{2×-0.8}=60$

$EP=\frac{VMP}{AVP}$

$=\frac{2-32X-1.2X^{2}}{2+16X-0.4X^{2}}=-1.8$

The products demand is inelastic since the EP is less than 1.
