Study Notes

Managerial Economics

  • Managerial economics is the study of how to direct scarce resources to efficiently achieve a managerial goal.

Basic Principles of Effective Management

  • Identify goals and constraints
  • Recognize the nature and importance of profits
  • Understand incentives
  • Understand markets
  • Recognize the time value of money
  • Use marginal analysis
  • Make data-driven decisions

Identify Goals and Constraints

  • Identify well-defined goals
  • Make decisions
  • Identify constraints

Recognize the Nature and Importance of Profits

  • Accounting Profit = Total Amount of Money – Cost of Producing Goods or Services
  • Economic Profit = Total Revenue – Total Opportunity Cost

Understand Incentives

  • Provide incentives to resource holders to alter their use of resources

Understand Markets

  • Consumer-Producer Rivalry: competing interests of consumers and producers
  • Consumer-Consumer Rivalry: among consumers, reducing negotiating power
  • Producer-Producer Rivalry: among producers, competing for customers
  • Government and the Market: may induce government intervention when disadvantaged in the market process

Recognize the Time Value of Money

  • Present Value: the current value of future cash flows
  • Example: $100 in 10 years at 7% interest rate is $50.83
  • Net Present Value: the sum of the present values of future cash flows
  • Example: purchasing a machine with a cost of Rs. 330,000 and a useful life of 5 years, yielding cost reductions of Rs. 50,000 to Rs. 90,000 per year

Use Marginal Analysis

  • Control Variable: the level of the managerial control variable that maximizes net benefits
  • Marginal Benefit (MB): the additional benefits from using an additional unit of the control variable
  • Marginal Cost (MC): the additional cost incurred by using an additional unit of the control variable
  • Example: finding the optimal level of control at which MB = MC

Make Data-Driven Decisions

  • Quantitative managerial decisions: using data to make decisions
  • Observation: collecting data to understand relationships between variables
  • Examples: regression analysis and using a spreadsheet to perform a regression
