Abstract: In the standard New Keynesian (NK) framework, an increase in inflation expectations raises consumption. This conventional result rests on strong general equilibrium effects and the assumption that households do not perceive expected real income losses when inflation expectations rise. In this paper, I disentangle the underlying economic mechanisms and show that the consumption response can easily turn negative once empirically relevant features are taken into account. I decompose the total effect into an intertemporal substitution channel and a negative real income channel, under the empirically supported assumption that inflation expectations do not fully pass through to nominal wage expectations. In the Representative Agent NK model, consumption still increases because households also receive profits, which offset expected real wage declines. By contrast, in a stylized Heterogeneous Agent NK model, the total effect may turn negative if the profit channel is dampened and the disconnect between inflation and nominal wage expectations is sufficiently strong. I further examine the role of the wealth effect, which reinforces the possibility of a negative consumption response.Presented: Directorate General Research Seminar (European Central Bank; Frankfurt), 56th Annual Conference of the Money, Macro and Finance Society (University of Reading; Reading), 28th International Conference on Macroeconomic Analysis and International Finance (University of Crete; Crete), 6th Behavioral Macroeconomics Workshop (Heidelberg University and Bamberg University; Heidelberg), ERMAS 2024 (Babeș-Bolyai University and National Bank of Romania; Cluj-Napoca), 4th Sailing Macro Workshop (Sapienza University of Rome; Ortygia, Siracusa), 3rd Naples School of Economics PhD and Post-Doctoral Workshop (NSE; Naples), Workshop on Households’ Inflation Expectations, Czech National Bank (CNB; Prague)
