For the total supply of labor to remain unchanged, the wage in the non-unionized sector must fall from w* to wNU wNU 2 4 5 6 7 8 9 10 11 12 17 17 18 19 20 21 21 2 3 4 5 7 27 31 35 8 10 36 41 45 12 * Elasticities of Labor Supply (Hours Worked) * Labor Supply for One- andTwo-Earner Households When higher wage rate leads to fewer hours worked: Labor supply curve is backward bending Income effect outweighs the substitution effect Elasticity of labor supply is negative * Equilibrium in a Competitive Factor Market Competitive factor market is in equilibrium when the prevailing price equates quantity supplied and quantity demanded Since workers are well informed, all receive the same wage and generate identical MRPL when employed * Equi
