What happens when technological advance makes available a new highly productive
capital good for which MP/P is greater than that of labor for which it is a substitute
resource?
A. Labor will replace the new capital because labor is now cheaper.

firm should use

A firm's demand schedule for a resource is the firm's marginal product schedule for the
resource.
295.
A competitive firm's marginal revenue product of labor will fall as it employs more
labor because the price of labor decreases as more of it is employed.
16-136
296.
The marginal revenue product curve for an input is downsloping because of the law of
diminishing returns.
297.
If MRP of labor < wage rate, a firm should hire more workers.
298.
Changes in the price of a product would not shift the demand for the resources needed
to produce the product.

If the demand for a product produced by an input decreases, the demand for the input
will also decrease.

input.
301.
The demand for a resource will shift left if the price of a substitute resource decreases.
302.
If the price of labor increases relative to the price of capital, and as a result the quantity

If two resources are complementary, an increase in the price of one will increase the
demand for the other.

The less the elasticity of product demand, the greater the elasticity of resource demand.

The elasticity of demand for labor varies inversely with the elasticity of demand for the

307.
To achieve profit maximization, a firm must produce the profit-maximizing output with
the least amount of economic resources.
308.
If a firm pays labor $5 and receives an MPL of 10, while paying capital $100 and
receiving an MPC of 100, to lower production costs it should hire more labor and less
