3. Entrepreneurship <strong>and</strong> Income<br />

A. Costs <strong>to</strong> the Firm<br />

Prices determine costs, not vice versa. (Recall that the<br />

“costs of production” are largely the prices of fac<strong>to</strong>rs.)<br />

The plethora of cost curves in mainstream texts assume<br />

fixed fac<strong>to</strong>r prices, <strong>and</strong> cannot explain the emergence of<br />

prices because they proceed from the viewpoint of an<br />

individual, “price taking” firm.<br />

Average costs per unit may vary <strong>with</strong> the level of output<br />

because of indivisibilities in fac<strong>to</strong>r inputs.<br />

B. Business Income<br />

A business owner’s gross income consists of: (a) interest<br />

on capital invested, (b) (implicit) wages for his managerial<br />

tasks, (c) rents of ownership-decision, <strong>and</strong> (outside<br />

the ERE) (d) entrepreneurial profit or loss.<br />

C. Personal Consumer Service<br />

Certain entrepreneurs (such as doc<strong>to</strong>rs <strong>and</strong> lawyers)<br />

sell their labor directly <strong>to</strong> the final consumer. These people<br />

are self-employed <strong>and</strong> earn a wage only in the implicit<br />

sense.<br />

D. <strong>Market</strong> Calculation <strong>and</strong> Implicit Earnings<br />

Implicit earnings can only be computed if there are<br />

explicit prices on an actual market <strong>with</strong> which <strong>to</strong> compare<br />

one’s gross income from a given activity.
