We provide new causal evidence of the link between gas prices and household inflation expectations and demonstrate that gas prices play a more significant role in shaping inflation expectations than previously suggested in the literature. We also show experimental evidence that informing households about the tax reduction leads them to adjust their inflation expectations downward.
