Bias in Survey Based Inflation Expectation: A Developing Country Perspective Vol. 31 Issue 01, 2026

Abstract

We studied the impact of phrasing on consumer inflation expectations in Pakistan using an online survey. Our results imply that optimal phrasing of the question can significantly reduce bias in responses. When the question is asked as an absolute change from PKR 100, responses are high and volatile, with many in multiples of tens and fifties. Moreover, we studied the impact of closed-ended questions on inflation expectations and found that responses to closed-ended questions suffer from central tendency bias. Our study also confirms the impact of information on the formation of inflation expectations. When presented with information about current inflation levels, respondents tend to lower their inflation expectations. Literature provides two possible reasons for this: information bias or social bias.
