Abstract

This study examines the relationship between inflation expectations and consumer spending.

Using a combination of original consumer survey data on inflation expectations and scanner data on the actual expenditure, we examine whether higher inflation expectations generate greater current spending. The linked data also allows us to directly estimate the value of the elasticity of the intertemporal substitution (EIS) based on a standard macroeconomic model. We find that higher inflation expectations generate greater current spending compared with one year later. We find the value of the EIS significantly positive and approximately 0.1. On the other hand, liquidity-constrained consumers seem to decrease current expenditure in response to higher inflation expectations. This evidence implies that the impact of higher inflation expectations on consumers' intertemporal allocation may vary depending on the type of consumer.
