Study Notes
Introduction to Economics
- Economics comes from the Greek word "oikonomikos" meaning "the task of managing a household."
- Economics studies the economic behavior of people, individuals, households, firms, and governments.
- People economize because of endless human wants, limited resources, and the tendency to make the most of what they have.
- Economics studies how people allocate their resources to various alternatives to maximize gains.
Fundamental Economic Problems
- What to produce? - Deciding which goods and services to provide.
- How to produce? - Determining the methods and resources used for production.
- For whom to produce? - Figuring out who will benefit from the goods and services created.
- Are resources used economically? - Assessing efficiency and avoiding waste in resource allocation.
- Are resources fully employed? - Ensuring all available resources are utilized to their full potential.
- Is the economy growing? - Evaluating the overall growth and development of the economy.
Microeconomics and Macroeconomics
- Microeconomics focuses on the behavior of individual economic units, like consumers and businesses, to understand their decision-making processes.
- Macroeconomics examines the aggregate picture of the economy, studying national income, employment, and the impact of government policies.
Managerial Economics
- Managerial Economics applies economic theory and analytical tools to help organizations make effective decisions.
- It focuses on optimizing resource allocation and achieving organizational goals.
- It bridges economic theory and quantitative methods to solve business problems.
Economic Contributions to Business Decisions
- Choice of business area: Selecting the most suitable industry based on available resources.
- Choice of product: Identifying the optimal products to produce given market conditions and demand.
- Determining optimum output: Finding the ideal level of production to maximize profits.
- Choice of technology: Selecting the most efficient production methods and factor combinations.
- Acquisition of inputs: Making decisions on labor and capital resources.
- Determining product price: Setting prices that balance profitability and demand.
- Assessing economic environment: Understanding the economic landscape and opportunities for business growth.
Consumer Choice
- Effective Demand: Desire to buy, ability to pay, and willingness to pay are crucial for effective demand.
- Utility: The want-satisfying property of a commodity (product perspective) or the satisfaction derived from its possession or consumption (consumer perspective)
- Total Utility: The sum of utility derived from consuming all units of a commodity (TUx = U1 + U2 + U3 + U4)
- Marginal Utility: The additional utility gained from consuming one more unit of a commodity (MUx = TUn – TU(n-1))
- Cardinal Utility: Measures utility with a specific unit, expressed in "utils."
- Ordinal Utility: Utility is not numerically measured but can be ranked or ordered based on preference.
Law of Diminishing Marginal Utility
- As more units of a commodity are consumed, the additional (marginal) utility gained from each successive unit decreases, assuming other factors remain constant.
Assumptions of the Law of Diminishing Marginal Utility
- Units of consumption must be standard.
- Consumption must be continuous.
- Tastes and preferences remain unchanged.
- The good is normal (not addictive).
Indifference Curve Theory
- Developed by Hicks and Allen, this theory uses ordinal utility (comparing preference but not numerically measuring it).
- An indifference curve shows combinations of two goods that give a consumer the same level of satisfaction, meaning they are indifferent between these combinations.
Assumptions of Indifference Curve Analysis
- Only two goods are considered in the consumer's basket.
- Preferences can be ranked but not quantified.
- The consumer is never completely satisfied.
- Consumer choices are consistent.
- Goods are perfectly divisible.
Properties of Indifference Curves
- Downward sloping to the right: Indicates that to gain more of one good, the consumer must give up some of the other.
- Higher curves represent higher utility: As we move higher in the indifference map, the level of utility increases.
- Indifference curves cannot intersect: This would violate the assumption of consistent preferences.
- Convex to the origin: This indicates diminishing marginal rate of substitution and imperfect substitutability between goods.
Marginal Rate of Substitution (MRS)
- MRS is the rate at which one commodity is substituted for another while maintaining the same level of total utility.
- MRS is usually negative, indicating that to gain more of one good, the consumer must give up some of the other.
- MRS diminishes as we move along the indifference curve, meaning the consumer is willing to give up less of one good for each additional unit of the other.
Special Types of Indifference Curves
- Perfect substitutes: Straight downward sloping indifference curves, where the consumer is willing to trade one good for the other at a constant rate (e.g., different brands of water).
- Perfect complements: Right-angled (L-shaped) indifference curves, where goods are consumed in a fixed ratio (e.g., a pair of shoes).
- Both commodities of dislike: Concave indifference curves, where the consumer dislikes both goods (e.g., allergic to seafood).
- One good and one bad: Upward sloping indifference curves, where one good is desirable, and the other is a bad (e.g., industrial development vs. pollution).
