Key Economic Concepts (Simplified)
Hourly wage: Pay for one hour of work.
Weekly hours worked: Total hours worked in a week.
Weekly earnings: Hourly wage × weekly hours.
Higher wage scenario: When pay increases significantly.
Choice of hours: With higher wages, workers may work fewer hours, earn more, or
both.
Example choice: A worker keeps the same income but works fewer hours, gaining free
time.
Real hourly earnings: Wage adjusted for inflation (shows true buying power).
g
Working hours trend: Average annual hours have fallen in many countries.
Economic progress effect: People may choose more goods, more free time, or both.
Income per capita: Average income per person (includes wages, profits, interest).
fro
Historical trend: Income rose while work hours declined.
Free time differences: Richer countries often work less and have more leisure.
Living standards: Most countries’ living standards improved, but work–leisure balance
varies.
Key question: Why do some nations prefer more leisure while others keep long work
hours?
ol
Work–Leisure Choice Model
Disposable income: Money available to spend after taxes and transfers.
Karim’s example: Shows trade-offs between working time and free time.
el
Income function: ( y = w \times h ) (income = wage × hours).
Constraint: Limited time and wage rate restrict choices.
Decision factors: Preferences, wage, and available time.
Consumption spending: Money spent on goods/services.
th
Preferences and Trade-Offs
Indifference curve: Shows combinations of goods giving equal satisfaction.
Slope: How much of one good you’d give up for more of another.
Higher curve: Greater satisfaction.
Downward slope: To get more of one thing, you give up another.
Flattening curve: Willingness to trade decreases when you already have a lot.
Steep curve: Willingness to trade increases when you have little.
