Demonstration effect
Topic: Consumer Behaviour, Demand and Elasticity · NCERT: Beyond NCERT
Meaning
The demonstration effect is the tendency of people to copy the consumption habits of richer groups or richer countries. James Duesenberry described it in 1949. Ragnar Nurkse (1953) applied it across countries. When people imitate richer lifestyles, their consumption rises and their savings fall. In a developing economy, this reduces the money available for capital formation, which means building factories, machines and infrastructure.
Example
A middle-income household in a small town sees city families or foreign lifestyles on social media. It then buys a premium smartphone and eats out more often, and saves less of its income than before.
Don't confuse with
- Bandwagon effect: demand for a particular good rises because many people already buy it. The demonstration effect is about copying the overall lifestyle of those above you, and its main result is lower savings.
- Conspicuous consumption: spending to display your own status. The demonstration effect is imitating others' spending.
