Study Notes

Learning Objectives

Demonstrate optimal working time choices among labor owners.
Analyze how workers respond to changes in factor prices.
Understand the derivation of the labor supply curve.

Time Allocation Model

Developed by Gary S. Becker in 1965.
Focuses on optimal time allocation between work and leisure.
Collective time allocation decisions determine the labor supply curve.

Assumptions of the Model

Individuals can distribute their time between leisure and labor.
Work does not provide utility; leisure does.
Individuals are willing to work if compensated adequately.
Utility is derived from consumption made possible by income.

Elements of the Model

H: Maximum available time.
h: Time spent on leisure.
L: Time spent on work, where H = h + L.
Wage income (Y) expressed as Y = wL, where w represents the wage rate.
Total expenditure is represented as Y = pC, where p is price and C is consumption.

Utility Function and Indifference Curve

Utility represented as U(h, C).
Indifference curves illustrate combinations of leisure and consumption yielding the same utility level.

Budget Constraint

Fits the equation H = h + L.
Rearranged to express income based on working hours and leisure: Y = w(H - h).

Choice of Optimal Working Time

Individuals strive to maximize utility (U) under the given income constraint.
Maximization involves Lagrangean formulation: α(h, C, λ) = U(h, C) + λ(wH - wh - pC).

Substitution Effect

An increase in wage affects leisure and work time allocations.
Higher wages induce a decrease in leisure time and an increase in work time.
Graphically, represents changes in consumption and leisure time based on shifts in the wage rate.

Income Effect

In the face of a wage increase, the overall value of total time resources rises.
Both consumption (C) and leisure (h) are considered normal goods, causing increased leisure with rising wages.
Entails a decrease in working hours (L) due to increased disposable income.

Final/Net Effect

Combines results of substitution and income effects.
Change in leisure (h) can be derived as an aggregate of the two effects, showing varying influences based on the wage changes.

Graphical Representation

Illustrates how the substitution effect (SE) and income effect (IE) impact decisions on leisure and labor.
Depictions show shifts in consumption curves based on changes in w, highlighting the relationship between labor supply and time allocation decisions.

Labor Supply Curve Implications

The resulting labor supply curve reflects the interplay between SE and IE, capturing changes in labor supply based on wage fluctuations.

Homework Reminder

Analyze substitution and income effects under decreased wages for deeper understanding.
