Economic models are important tools that help us understand inflation and how it affects us. They give us a way to look at how different parts of the economy interact with each other.

1. What is Inflation?

   • Inflation is when the overall prices for things we buy, like food and clothes, go up. This means our money buys less than before.
   • For example, in Sweden, inflation was about 2.8% in 2021. But then it jumped to around 5.8% in 2022. This shows how quickly things can change.

2. Key Economic Models:

   • Demand-Pull Inflation Model: This model talks about how when people want to buy more stuff, prices can go up. For instance, if families earn 10% more money, they might want to buy more things, which can push prices higher.
   • Cost-Push Inflation Model: This model explains how when it costs more to make things (like when worker wages go up or raw materials cost more), prices go up too. For example, if oil prices rise by 15%, the cost to transport goods will increase, which can lead to higher prices for products.

3. Effects of Inflation:

   • Inflation can hurt savings and investments because it makes money worth less.
   • In 2022, real wages in Sweden dropped about 2.4% because of inflation. This shows how inflation reduces what people can buy with their earnings.

By using these models, experts can predict and manage how inflation impacts the economy.
