Abstract
Communication around inflation has become a central focus in both economic research and policy, as managing inflation expectations is critical for effective monetary policy. Despite intensified efforts by central banks to inform the public, recent studies show that standard information treatments often have limited success, particularly when targeting medium-term expectations or audiences with low financial literacy (Cavallo et al., 2017; Coibion et al., 2022; Nghiem et al., 2024). While financial markets typically absorb central bank messages efficiently, reaching the broader public remains a challenge (Blinder et al., 2024). One potentially approach, emphasized by Shiller (2019) and Harari (2018), is the use of narratives - relatable and emotionally appealing stories that may foster deeper engagement and retention of economic information. This project aims to investigate whether narratives are more effective than standard quantitative or qualitative inflation information in shaping households’ inflation expectations. Furthermore, we aim to examine whether framing macroeconomic developments in the form of relatable stories enhances the persistence of belief updates, particularly among individuals with limited financial knowledge. This study will address a gap in the literature by examining the impact of emotionally engaging narrative communication on non-expert audiences and will offer policy-relevant insights into how central banks can enhance the effectiveness of their outreach to the general public.

Experimental Design

Experimental Design
We will conduct a randomized controlled trial (RCT) with a representative sample of 3.000 German households. Participants will be randomly assigned to one of five groups: a control group and four treatment groups. One treatment group will receive standard quantitative information about past, current, and future inflation, while another will be provided with the same information in qualitative form. The remaining two treatment groups will receive either the quantitative or qualitative information, but with the added component of a relatable narrative designed to enhance emotional engagement with the information. We will elicit participants objective and subjective inflation expectations before and after treatment through asking different questions, allowing us to assess the effect of each treatment in bringing expectations closer to the 2% target rate. We will include post-treatment survey questions to assess participants’ levels of understanding of the information, and their engagement, emotional response, and identification with the narrative. We plan to conduct a short follow-up survey after two weeks to evaluate the persistence of the effects.
