Document Summary

Income effect dominating substitution effect: when the supply curve bends backward. Leisure is more beneficial to individual than income. @ high wages the income effects dominates. Fixed quantity of labor willing to work per week no matter the wage: vertical line in fixed hours spot. Income effect: causes individuals to reduce hours and invest in leisure because they believe their income is high enough. Substitution effect: causes individuals to sacrifice leisure for income because the wages are too high or opportunity cost of not working is too high. Equilibrium wage: the wage where there is neither shortage or surplus in labor income effect versus substitution effect definition= The income effect will decrease labor supply while the substitution effect will increase labor supply. Externalities: the costs/benefits of a market activity that affect a third party (e. g. pollution, waste. Occur when private cost/benefit diverges from social cost/benefit (external cost exists)

(10 points) In It is commonly argued that the individual labor supply curve should be backward bending: at low wages, an increase in the wage results in an increase in work hours, but at high wages an increase in the wage results in a decrease in work hours. Using the concepts of income and substitution effects, explain (in your own words) why the labor supply curve should be backward bending.

Suppose a firm employs both labor and capital. If the ratio of marginal product to price of labor is 50/$10 and the ratio of marginal product of capital to price of capital is 60/$12, the firm should
