Business I / The Industrial Revolution
Practice question · Multiple choice

Allen argues the spinning jenny was invented in Lancashire rather than Bengal, where cotton skills were older and deeper. What made Britain the profitable place to mechanise?

Hints
  1. A machine substitutes energy for labour. Ask what the two cost in each place.
  2. Would you buy a labour-saving device where labour is nearly free?
Show the answer

C. Its unusual price ratio: high wages and cheap coal

Why

Invention responds to relative prices, and the jenny paid for itself only where wages were high relative to fuel, the same device was a bad investment in Bengal. It reframes the Industrial Revolution as an induced response to a local price structure rather than a burst of British genius.
