First Principles of Economics

Economics textbook by Paul Krugman and Robin Wells, sixth edition, published 2021 by Worth Publishers
The book is revised by Vitaly Terekhov

What You Will Learn in This Chapter

Four principles guiding individual choices
Four principles governing how individual choices interact
Three principles illustrating economy-wide interactions

The Principles: Individual Choice, Part 1

Choices are necessary due to scarce resources
Resource: anything usable for producing something else
Scarcity: a resource's lack of availability to satisfy all societal needs
Scarce resources include: minerals, lumber, petroleum, time, human skills, clean air, and clean water

The Principles: Individual Choice, Part 2

Opportunity cost: the value of the next best alternative forgone
Mark Zuckerberg's decision to drop out of Harvard exemplifies opportunity cost

The Principles: Individual Choice, Part 3

Decisions often involve trade-offs, comparing costs and benefits
Marginal decisions focus on "how much" – whether to do a little more or less of something
Marginal analysis studies marginal decisions

The Principles: Individual Choice, Part 4

Marginal decision: a decision made at the margins of an activity (e.g., studying a bit more or less)
Marginal analysis: the study of marginal decisions

The Principles: Individual Choice, Part 5

People respond to incentives
Incentive: anything offering rewards for behavior change
Example: policies to reduce pollution, choosing between education or financial reward

Learn by Doing: Practice Question 1

Costco offers free samples; customers eat until full. Do they face opportunity cost?
- Answer: Yes

Learn by Doing: Practice Question 2

Costco offers free samples; economists label this as an example of
- Answer: Bad Incentives

The Principles: Interaction of Individual Choices, Part 1

Gains from trade arise from specialization
Specialization: each person focuses on tasks they excel at

The Principles: Interaction of Individual Choices, Part 2

Markets typically move toward equilibrium
Equilibrium: an economic state where no individual benefits from changing their actions

The Principles: Interaction of Individual Choices, Part 3

Resources should be used efficiently for achieving societal goals
Efficiency: opportunities to benefit people without worsening others' situations

The Principles: Interaction of Individual Choices, Part 4

Equity: everyone gets a fair share; a condition
Markets typically lead to efficiency, but intervention can improve societal welfare in cases of market failure

Learn by Doing: Practice Question 3

Fast-food chains' task division (e.g., taking orders, preparing food, bagging) is an illustration of
Answer: Specialization

Learn by Doing: Practice Question 4

Low-skilled workers earning below poverty line is considered a failure related to
- Answer: Inequity

The Principles: Economy-Wide Interactions, Part 1

One person's spending is another's income
Recessions: decrease in business spending, less income, less spending leading to layoffs, rising unemployment

The Principles: Economy-Wide Interactions, Part 2

Overall spending can deviate from the economy's productive capacity
Government policy can influence spending to address these imbalances (e.g., recessions or inflation)

The Principles: Economy-Wide Interactions, Part 3

Increased economic potential leads to economic growth over time
Economic growth: increase in living standards over time
Economy's potential: total goods/services it could produce
Factors boosting potential: new technologies, availability of resources
Disparities in growth impacts: uneven distribution for different groups

Learn by Doing: Discussion Question 1

Wealthy people (like Oprah Winfrey and Jeff Bezos) still face scarcity
