What effect of the lightbulb illustrates the economic multiplier concept beyond just the sale of the product?
Answer
The ability to run factories 24 hours a day and create new employment sectors
The lightbulb allowed industries to extend operational hours well beyond daylight, fundamentally changing labor patterns and overall productivity. This efficiency gain is a prime example of an economic multiplier, where the invention acts as a catalyst for growth across multiple sectors. This leads to the creation of entirely new types of employment and economic activity that generate value far exceeding the initial sales of the bulbs themselves.
