Exposure to Daily Price Changes and Inflation Expectations

Abstract: We show that, to form aggregate inflation expectations, consumers rely on the price changes they face in their daily lives while grocery shopping. Specifically, the frequency and size of price changes, rather than their expenditure share, matter for individuals' inflation expectations. To document these facts, we collect novel micro data for a representative US sample that uniquely match individual expectations, detailed information about consumption bundles, and item-level prices. Our results suggest that the… Show more

“…Alternatively, if the price of goods purchased by households rises today and they do not alter their spending patterns much, their spending will be higher and they will likely raise their inflation expectations, since households generally form expectations based on the prices of goods they typically purchase (D'Acunto, Malmendier, Ospina, and Weber 2019). A positive correlation between spending and inflation expectations therefore need not imply a causal relationship from expectations to spending decisions.…”

“…We leave out of the analysis a variety of other plausible theories, which help explain different types of data. These include wishful thinking (e.g., Brunnermeier and Parker, 2005;Caplin and Leahy, 2019); 9 For a detailed discussion of this difference, see the end of Section 5 and the accompanying Appendix B. over-weighting of personal experience (e.g., Malmendier and Nagel, 2016;D'Acunto, Malmendier, Ospina, and Weber, 2019;Das, Kuhnen, and Nagel, 2020); adaptive learning (e.g., Eusepi and Preston, 2011;Evans and Honkapohja, 2001;Sargent, 2001); uncertainty shocks (e.g., Bloom, 2009a;Baker, Bloom, and Davis, 2016); robustness and ambiguity (e.g., Hansen and Sargent, 2012;Ilut and Schneider, 2014;Bhandari, Borovička, and Ho, 2019); non-Bayesian belief contagion (e.g., Carroll, 2001;Burnside, Eichenbaum, and Rebelo, 2016); and other plausible departures from the fully rational model (e.g., Adam and Woodford, 2012;Gabaix, 2019;Molavi, 2019;Woodford, 2018).…”

“…If information access depends on an individual's gender, absent knowing the nature of the missing, inaccurate, or emphasized information, it may be difficult for individuals to correct these disparities. Research demonstrates substantial gender gaps in knowledge of fundamental economic parameters, which are used to inform consumption, financial, and labor market choices (D'Acunto et al, 2019;Dwyer et al, 2002). Our work points to disparate information access as one plausible determinant of these knowledge and behavior gaps.…”
