The ability of consumers to buy products X and Y is

The ability of consumers to buy products X and Y is

determined by budget constraints, which may be expressed graphically by the budgeting line

if you buy a stool, than a rope and a soap are a gift

Слайд 3

Assume that the consumer has a limited amount of money, which

Assume that the consumer has a limited amount of money, which

he will spend on the products X and Y

Suppose he'll spend the entire sum

Слайд 4

Budget Equation will be: The budgeting line is a set of

Budget Equation will be:

The budgeting line is a set of all

combinations of products X and Y that can be acquired, if consumer will spend his whole income

Quantity of Y, consumed for some definite period

Quantity of X, consumed for some definite period

Слайд 5

The inclination of the budgeting line: Quantity of Y, consumed for

The inclination of the budgeting line:

Quantity of Y, consumed for some

definite period

Quantity of X, consumed for some definite period

Слайд 6

Consumer balance The balance point can be found by tracing the

Consumer balance

The balance point can be found by tracing the budget

line on the map of indifference for products X and Y

Quantity of Y, consumed for some definite period

Quantity of X, consumed for some definite period

The balance point is a point of tangency of the budgeting line and indifference curve representing achievable combination of X and Y, which provides the highest level of utility

Слайд 7

At the tangency point the inclination of the indifference curve is

At the tangency point the inclination of the indifference curve is

equal to the inclination of the budgeting line:

This is the same model, which provides a quantitative approach

Слайд 8

The model suggests that the total utility of consumption is maximized

The model suggests that the total utility of consumption is maximized

if the consumer’s income is distributed so that the marginal utility per 1 ruble of expenses for each product is the same
