The equilibrium wage rate in an industry is determined by
whether workers or management are better at negotiating.
the intersection of the market demand curve for labor and the market supply curve for labor.
the strength of the substitution effect relative to the elasticity of demand for labor.
finding where the market supply curve indicates that the substitution effect and income effect
of a wage increase are offsetting.
Coal and iron ore are complements in the manufacture of steel. An increase in the price of coal
would lead to
an increase in the demand for iron ore as producers substitute more iron ore for coal in the
production process.
an increase in the supply of iron ore as iron ore producers see an opportunity to expand their
markets.
a decrease in the demand for iron ore as steel manufacturers reduce production of steel.
no change in the demand for iron ore since the steel makers must use both iron ore and coal if
they are to make steel.
The price elasticity of demand for a variable input will be greater
the easier it is for a particular input to be substituted for by other inputs.
the lower the price elasticity of supply of all other inputs.
the smaller the proportion of total costs accounted for by a particular variable input.
the fewer substitutes there are for the final product.
Assume that a perfectly competitive firm faces a fixed wage rate of $4 and a constant per–unit cost
of capital of $2. If the marginal product of labor and capital are 16 and 6, respectively, then to
maximize profits the firm should
use relatively more capital.
increase all inputs proportionately.
decrease all inputs proportionately.
use relatively less capital.
