ECN Tutorial Sheet 4 (2024) by University of Zambia - Production Theory and Market Structures - Economics

Description

This ECN Tutorial Sheet 4 from the University of Zambia is a comprehensive practice resource covering two major areas of microeconomic theory: Production Theory and Market Structures. The Production Theory section requires students to define and explain the properties of isoquants, calculate the marginal rate of technical substitution (MRTS), and analyze returns to scale for given production functions (Q = KL and Q = L^0.75 K^0.25), including deriving short-run functions and comparing marginal and average products. It also includes a cost table completion exercise and a graphical illustration of the three stages of production. The Market Structures section focuses on perfect competition and monopoly, asking students to explain why perfectly competitive firms are price takers, distinguish between short-run and long-run equilibria, and describe the factors that drive profits to zero in the long run. For monopoly, the tutorial requires drawing and labeling demand and marginal revenue curves from an inverse demand function (P = 100 - Q), deriving cost curves from a given total cost function (TC = 50Q), and calculating and illustrating deadweight loss. This tutorial sheet is an essential study aid for university students pursuing degrees in economics to master analytical and graphical skills for exam preparation. To reinforce your understanding of these advanced concepts, download and work through the tutorial problems.
