Robert Hall from Stanford University and Michael Woodford from Columbia University won the 2026 Nobel Prize in economics. The prize committee chose them for their work on how small economic decisions affect the whole economy. Their research shows how governments can help keep the economy stable.
A main part of their work is the idea of "sticky prices." In a perfect world, prices would change every second. But in the real world, prices often stay the same for a long time. This means prices do not move quickly when the economy changes. This delay can cause problems for businesses and people.
Timo Boppart, a member of the prize committee, used an ice cream shop to explain this. An ice cream shop does not change its prices every day. Instead, it might keep the same prices for a whole season. Because the prices stay the same for months, they are "sticky." This explains why markets do not always react to news immediately.
This idea is important for "New Keynesian economics." Old models thought markets always balanced themselves quickly. But these models could not explain why economies have hard times. New Keynesian economics shows that prices and wages do not change immediately. This helps economists understand how economies grow or fall.
The research is also important for history. For example, during the 1970s, the world had "stagflation." This was a time when inflation and unemployment both went up. This was a very difficult period. Understanding sticky prices helps explain why these unusual problems happen. This research helps leaders plan how to keep the economy steady during difficult times.
