Over the last 10 years the price of a cell phone has declined dramatically. At the same time, taste and preferences for cell phones has increased substantially. Using a supply and demand diagram of the market for cell phones, explain what likely caused this outcome.
The market adjustment can be described as follows:
1) First there is a rise in demand - this is when consumers
realize the benefits of the new technology.
A cell phone is more useful the more people have it - they show
network effects - and soon more and more people
are buying cell phones until the existing producers just can't keep
up. This is shown as the shift from D0 to D1 keeping supply curve
fixed at S0; price of a cell phone rises.
2) More producers get to hear that there are sweet profits to be made in the cell phone industry; this motivates them to try and imitate existing technology. As more and more producers join the market, the supply curve shifts outward from S0 to S1; price falls.
