Background: Some Basic Economic Concepts
Introduction
Economics is a social science that analyzes how societies allocate scarce resources to satisfy unlimited wants. Recent global events, such as elections and international conflicts, highlight the importance of understanding economic principles.
Key Point: Economics helps us interpret and analyze major events and policy decisions.
Example: U.S. elections and the Ukraine-Russia war have significant economic implications.
Scarcity and the Economic Problem
Scarcity is the fundamental concept in economics, referring to the limited nature of resources compared to unlimited human wants. This leads to the economic problem: deciding what to produce, how to produce, and for whom to produce.
Definition: Scarcity means that resources (such as time, money, labor, and raw materials) are insufficient to fulfill all human wants.
Economic Problem:
What goods and services should be produced?
Which production methods should be used?
Who receives the goods and services?
Key Point: Even wealthy societies face scarcity because wants always exceed available resources.
Example: Choosing between funding healthcare or education with limited government budgets.
Choice and Opportunity Cost
Scarcity forces individuals and societies to make choices. Every choice involves an opportunity cost, which is the value of the best alternative forgone.
Definition: Opportunity Cost is the value of the next best alternative that is given up when a decision is made.
Key Point: Only the value of the best alternative is considered, not all possible alternatives.
Example: If you spend time studying instead of working, the opportunity cost is the wages you could have earned.
Types of Opportunity Cost
Economists assume that firms and households are rational, making decisions where benefits exceed costs. Opportunity costs can be categorized as follows:
Monetary Cost ($ cost): The value of goods or money given up.
Time Cost: The value of time lost, such as foregone wages.
External Cost: Costs imposed on others, such as pollution.
Case Study: The Costs of University Education
Attending university involves both explicit and implicit costs, as well as external costs covered by others.
Explicit Costs: Tuition and books.
Implicit Opportunity Cost: Lost wages from not working.
External Costs: Financial support from loans and donations.
Annual Student Costs Table
Category | Item | Amount |
|---|---|---|
Student Costs | Tuition and fees | $3,000 |
Books and supplies | $2,500 | |
Foregone income | $22,000 | |
Total student costs | $26,800 | |
Others' Costs | Quebec Student Loans | $12,000 |
Gifts and donations | $500 | |
Total other costs | $12,500 | |
Total Costs | $39,300 | |
Additional info: Tuition and fees represent less than 1/8 of the total cost of university education, with foregone income being the largest component.
Evaluating University Education: Benefits vs. Costs
Economists recommend attending university only if the extra benefits exceed the total costs. Benefits include higher future earnings and improved employment prospects.
Key Point: The decision to pursue higher education should be based on a comparison of expected benefits and opportunity costs.
Example: Median annual earnings increase with higher levels of education, as shown in national statistics.
Median Annual Earnings by Education Level (2015)
Education Level | Women (Canada) | Men (Canada) |
|---|---|---|
High school diploma | ~$40,000 | ~$55,000 |
College diploma | ~$55,000 | ~$70,000 |
Bachelor's degree | ~$80,000 | ~$100,000 |
