# Surplus Produce

## Definition

The portion of a worker's output that exceeds their own consumption needs and
is therefore available for exchange. Smith argues that the certainty of being
able to exchange surplus produce for the products of other workers' labour
is what encourages every person to dedicate themselves to a particular
occupation. Surplus is thus both the material prerequisite and the incentive
for specialisation.

## Source Chapter

Book I, Chapter 2: "Of the Principle which gives Occasion to the Division
of Labour"

## Context

Introduced in the passage describing the emergence of specialised trades in
a tribal society. The armourer, carpenter, smith, and tanner each produce
more of their specialty than they can personally consume, and exchange the
surplus for other goods, reinforcing their commitment to specialisation.

Production

## Smith's Original Wording

"And thus the certainty of being able to exchange all that surplus part of
the produce of his own labour, which is over and above his own consumption,
for such parts of the produce of other men's labour as he may have occasion
for, encourages every man to apply himself to a particular occupation."
