-# Division of Labour
-
-## Definition
-
-The separation of a work process into a number of distinct tasks, each performed
-by a specialised worker, resulting in a significant increase in the productive
-powers of labour. Smith identifies it as the principal cause of improvement in
-the productive capacity of any trade, art, or manufacture. The effect arises
-from three circumstances: increased dexterity, saved time in transition between
-tasks, and the invention of labour-saving machinery.
-
-## Source Chapter
-
-Book I, Chapter 1: "Of the Division of Labour"
-
-## Context
-
-The division of labour is the central argument of the chapter. Smith opens by
-asserting that it is the greatest source of improvement in productive powers,
-then illustrates it through the pin-factory example, explains its three causal
-mechanisms, and concludes by showing how it generates universal opulence through
-exchange.

-## Smith's Original Wording
-
-"The greatest improvements in the productive powers of labour, and the greater
-part of the skill, dexterity, and judgment, with which it is anywhere directed,
-or applied, seem to have been the effects of the division of labour."
-
-## Modern Interpretation
-
-The division of labour remains a foundational concept in economics and
-organisational theory. Modern extensions include specialisation theory,
-comparative advantage (Ricardo), and the study of transaction costs that
-determine the boundaries between internal division and market exchange (Coase).
