Answer to Question 1

D

Answer to Question 2

a) A forecast of higher rainfall this year is likely to increase the demand for umbrellas. An increase in the demand for umbrellas will push the price of umbrellas up, and hence, increase the value of marginal product of labor. This will increase the demand for labor, which will cause an increase in the wage rate and the employment level in the firm.

b) Raincoats are substitutes to umbrellas. With a decrease in the price of raincoats, it is likely that the demand for umbrellas will fall. This will cause a decrease in the price and in the value of marginal product of labor employed by the firm. The result will be a fall in the demand for labor, which will cause a decrease in the wage rate and the employment level in the firm.

c) Labor-saving technology is a type of technology that can substitute for existing labor inputs, reducing the marginal product of labor. Hence, the use of such technology will decrease the value of marginal product of labor, which will result in a fall in the demand for labor. Eventually, there will be a decrease in the wage rate and employment level in the firm.
