It decreases (i.e. shifts to the left of the demand curve)B. It increases (i.e. shifts to the right of the demand curve)C. Not enough information to answer 2. Does an increase in the wage causes leisure always to increase, because leisure is a normal good?A. YesB. NoC. Only if the substitution effect dominates the income effectD. Only if the income effect dominates the substitution effect27. Describe the concept of the marginal rate of technical substitution. Explain.69. If the price of labor falls relative to the price of capital, and as a result the quantity of capital employed decreases, it can be concluded that: A.
