Study Notes
Introduction to Economics and Scarcity
- Economics is the study of how societies allocate scarce resources to satisfy unlimited wants.
- Scarcity arises when demand for a good or service exceeds its availability.
What is Economics?
- Economics analyzes the choices made by individuals, businesses, governments, and nations to allocate limited resources.
- These choices have ramifications in various fields like politics, psychology, business, and law.
Studies Demand and Supply
- The law of supply and demand describes how price changes impact supply and demand.
- As price increases, supply rises while demand declines.
- As price drops, supply constricts while demand grows.
Studies Consumption, Production and Distribution of our Scarce Resources
- Economics focuses on analyzing choices to allocate limited resources.
- It affects areas like politics, psychology, business, and law.
Etymologically, “ΟΙΚΟΝΟΜΙΑ”
- The word "economics" derives from the Greek word "oikonomia."
- "Oikonomia" means "household management" or "management of household affairs."
- It encompasses how people earn and spend income on necessities, comforts, and luxuries.
Studies of How Society Manages its Scarce Resources (Mankiw 2018)
- Resources are allocated through combined choices of individuals and firms instead of a powerful dictator.
- Economists study how people make decisions regarding work, consumption, savings, and investments.
Efficient Allocation of Society's Scarce Resources in Meeting the Unlimited Demands
- Scarcity is an economic concept where individuals allocate limited resources to meet needs.
- Demand exceeding availability creates scarcity and affects the monetary value of goods and services.
Economics as a Social Science
- Economics is a social science as it studies how people interact and make decisions related to resource allocation and production.
Mankiw's Ten Principles of Economics
- How do people make their decisions?
- People face trade-offs.
- The cost of an item is its opportunity cost (what is sacrificed to get it).
- Rational people seek to maximize their utility.
- People respond to incentives.
- How people interact with each other?
- Trade makes everyone better off.
- Markets are a good way to organize economic activity.
- Governments can sometimes improve market outcomes.
- How the entire economy works?
- A country's standard of living depends on its ability to produce goods and services.
- Growth of money leads to inflation.
- Society faces a short-run trade-off between inflation and unemployment.
Trade-offs
- In economics, a trade-off arises when choosing one thing means losing another opportunity.
- Every choice involves a trade-off, sacrificing something to gain something else.
Opportunity Cost
- Opportunity cost is the value of the next best alternative forgone when making a decision.
- Understanding opportunity costs is crucial for making informed choices.
Unlimited Human Demands
- Human desires and needs are unlimited, while resources are limited.
- This inherent conflict highlights the importance of resource allocation in economics.
Needs & Wants
- Needs are essential for survival (e.g., food, water, shelter.)
- Wants are desires that enhance the quality of life.
Hierarchy of Needs (Maslow)
- Physiological: Food, water, breathing, homeostasis, sexual reproduction.
- Safety: Protection, security, stability, freedom from fear.
- Love and Belonging: Friendship, family, intimacy, belonging.
- Esteem: Self-esteem, confidence, respect from others.
- Self-actualization: Achieving personal potential, fulfillment of desires.
What is Scarcity?
- Scarcity means that society has limited resources to produce goods and services.
- It occurs when demand for a good exceeds its availability.
Economic Resources – Finite
- Economic growth relies heavily on Earth's resources, which are ultimately finite.
- This dependence is unsustainable and has negative environmental consequences.
Factors of Production
- Land: Includes natural resources and land for agriculture or commercial use.
- Labor: Effort and work involved in production.
- Capital: Money and capital goods (machinery, tools) used in production.
- Entrepreneurship: Combines other factors creatively to produce goods/services.
Gross Domestic Product (GDP)
- GDP measures the total monetary or market value of the finished goods and services produced within a country's borders in a specific period.
- It serves as a scorecard of a country's economic health.
GDP Formula
- GDP = Consumption (C) + Government Spending (G) + Investment (I) + Net Exports (NX)
Gross National Product (GNP)
- GNP is the total monetary value of products and services produced by a country's residents, both domestically and overseas, in a specific period.
- It accounts for income earned by residents from investments abroad, subtracting income earned by foreigners.
Understanding GNP
- GNP measures the output of a country's residents (regardless of their location).
- It includes output by residents abroad but excludes output by foreigners in local markets
The Difference Between GNP and GDP
- The major difference between GNP and GDP largely stems from considering whether income is generated by domestic or foreign residents.
