Document Summary

Chapter 18: the markets for the factors of production. Factors of production: the inputs used to produce goods and services. Labour, land, and capital are the most important! The demand curve for a factor of production is a derived demand. A irm"s demand for a factor of production is derived from its decision to supply a good in another market. Production function: the relationship between the quantity of inputs used to make a good and the quantity of output of that good. Marginal product of labour: the increase in the amount of output from an additional unit of labour. Diminishing marginal product: the property whereby the marginal product of an input declines as the quantity of the input increases. Proit from an additional worker = worker"s contribution to revenue - Value of the marginal product: the marginal product of an input times the price of the output.

23.

b. increasing the demand for non-union made goods

c. increasing the productivity of union workers

d. increasing the demand for union-made goods

12. If a firm wants to maximize its profits, it should

a. equates the marginal revenue product for each input to the price of the input

b.hire unskilled labour rather than skilled labour since unskilled labour is cheaper

c. hire lots of capital and very little labour since labour needs to be trained

d. equate the marginal physical product for each input to the price of the input

10. A profit-maximizing monopolist will hire labour up to the point where

b. advances in telecommunications and computer networking.

c. support from organized labour.

d.sharp increases in the cost of overseas labour.

8. Suppose firms in an industry hire unskilled labour and skilled labour. unskilled labour is a substitute for capital and skilled labour is a complement with capital. A decrease in the real price of capital would:

a. cause the demand for unskilled labour to increase and the demand for skilled labour to decrease. the wage of unskilled labour would rise relative to the wage of skilled labour

b. cause the demand for both kinds of labour to decrease. wages rates of both kinds of labour would decrease too.

c. cause the demand for labour to increase, raising wages of both skilled and unskilled labour.

d. cause the demand for unskilled labour to decrease and the demand for skilled labour to increase. the wage of unskilled labour would decrease relative to the wage of skilled labour.
