In the indifference curve budget line model of labor supply,

labor is measured along the horizontal axis and consumption is measured along the vertical axis.

consumption is measured along the horizontal axis and labor is measured along the vertical axis.

In the indifference curve budget line model of labor supply, the slope of the indifference curve is used to measure

the wage rate.

One deficiency of the labor-leisure indifference curve analysis is that because indifference curves are always tangent to the worker’s budget line, the model cannot explain why some people choose not to work.
