Number of Credits 5
Academic Year 1

Microeconomics is an introductory course in the theory of markets with relevant applications to business, social and individual issues. This course introduces economic analysis of individual, business, and industry choices in the market economy. Topics include; the price mechanism, demand and supply, optimizing economic behavior, costs and revenue, market structures, factor markets, and market failure. It also provides introductory analysis of the role of governments in seeking to ensure the efficient operation of markets.

  • To introduce economic theories, tools and methods of analysis.
  • To understand the economic environment which functions through individuals, firms, industries, and government.
  • To identify the outcome and pricing decisions of firms operating under difference market conditions.
  • To understand the government microeconomic policy and its economic impact on individuals and businesses.

Upon completion of this course, the students will be able to:

  • Define economics and explain microeconomic concepts
  • Use the supply and demand model to determine the equilibrium price and quantity in a market
  • Use marginal analysis to explain maximizing behavior of firms and Individuals.
  • Describe how price and output decisions are made in different market structures.
  • Understand the application of microeconomic principles on business decision making.
  • Describe the conditions that may lead to market failure and government’s intervening role.
