Quantified Impacts of Mobile Phone Adoption in the Kerala Fish Market

Information and Market Efficiency

In a region with many isolated local markets for a perishable good, sellers historically had little information about prices in other locations, leading to significant price differences and occasional waste from unsold goods. A new technology is introduced that gives all sellers instant access to real-time price data from every market. Which of the following outcomes is the most direct and significant consequence of this technological change?

The introduction of a technology that provides real-time price information across multiple, previously isolated local markets for a perishable good will result in economic gains for every single participant group involved (producers, consumers, and intermediaries).

Information, Behavior, and Market Outcomes

Mechanism of Market Price Convergence

A group of producers of a perishable good, who operate in several geographically separate local markets, gain access to a new technology that provides them with real-time price information for all locations. Arrange the following events in the logical order they would occur, showing how this new information transforms the market.

After a new technology provided widespread, real-time price information in a previously fragmented market for a perishable good, different groups were affected in distinct ways. Match each market participant or entity with the primary outcome they experienced.

When producers in a fragmented market for a perishable good gained access to real-time price information, they could actively seek out the specific locations offering the highest prices to maximize their income. This strategic behavior, aimed at capturing economic gains that arise from temporary market inefficiencies, is an example of ________.

In a large city, flower vendors operate in several distinct neighborhoods. Historically, a lack of communication meant that on any given day, a surplus of unsold flowers in one neighborhood could coincide with a shortage and high prices in another. When these vendors adopt a smartphone app that shows real-time supply and demand data for all neighborhoods, the overall price for flowers across the city stabilizes, and less product is wasted. Which economic principle best explains why this technological change led to these specific outcomes?
