Formula for Adaptive Expectations
Adaptive expectations is a model of how economic agents form their expectations about future inflation. It posits that the expected inflation for the current period () is based on the recently observed actual inflation, specifically the inflation rate from the previous period (). This relationship is captured by the formula: This formula is a key component in explaining how inflation can persist or accelerate over time.

Consider an economic model where individuals' expectations for this year's inflation are determined solely by last year's actual inflation rate. If the actual inflation rate is steadily increasing each year, then individuals' expectations will consistently be an underestimate of the actual inflation that occurs.

An economy's inflation expectations are formed based on the previous period's actual inflation rate. The table below shows the actual inflation rate for Years 1 through 4. Match each subsequent year (the term) to its corresponding expected inflation rate (the definition).
Year Actual Inflation 1 2% 2 3% 3 5% 4 4% In an economic environment where people's expectations about future inflation are based solely on the inflation rate of the most recent past period, suppose the actual inflation rate was 2.5% in 2022 and 4.0% in 2023. Based on this model, the expected inflation rate for 2024 would be ____%.
