Decomposition of Consumer Sentiment and the Effects of Its Cyclical Component (Job Market Paper)

[Conference Presentation: the 2024 SEA, the NTxEC 2024, the 2024 MEG, the 2024 WEAI, the 2024 CEA, the 2024 EEA, the 2024 WERI]

Conventional empirical models occasionally incorporate sentiment to explain business cycle movements but rarely distinguish consumer optimism or pessimism from overall sentiment level. In this paper, I decompose consumer sentiment into trends and cycles using five filtering methods, with the cycles representing consumer over-optimism or pessimism. To mitigate discrepancies arising from specific statistical methods, I construct an average cycle based on a suite of five distinct commonly used measures. Using the average cyclical sentiment, I analyze the impact of sentiment on inflation expectations and macroeconomic variables. When using monthly U.S. data from 1978 to 2023, I find that cyclical sentiment significantly impacts inflation expectations, unemployment, and industrial production. However, the responses of core CPI inflation and CPI inflation to cyclical sentiment are ambiguous. I also incorporate several additional variables related to personal income, consumption, financial markets, and the labor market to examine their responses to cyclical sentiment. All these variables also exhibit short-lived but significant responses to cyclical sentiment movements.

From Beliefs to Prices: Analyzing How Inflation Expectations Affect Inflation Distribution (with Jose Barrales-Ruiz, Mikidadu Mohammed, Irina Panovska)

[Conference Presentation: the 2024 SEA]

This paper investigates how the distribution of inflation expectations influences realized inflation across its entire distribution. We find that shocks to median inflation expectations increase the median inflation rate for up to three years, and subsequently generate persistent upside risks in inflation that endure for more than six years. By analyzing higher-order moments; specifically, the standard deviation and skewness of inflation expectations, we show that greater disagreement among agents has distinct impacts on the distribution of the inflation rate. While an increase in the standard deviation amplifies right-tail inflation risks and generates quantile-dependent effects at the 90th percentile of the inflation distribution, a negative skewness shock temporarily shifts the distribution without any quantile-dependent effects. Our results highlight the critical importance of the distributional properties of inflation expectations for understanding and managing inflation risks, underscoring the need for well-anchored expectations to promote macroeconomic stability.

Nonlinear Effects of Economic Variables on Disagreements about Inflation Expectations
[Conference Presentation: the SEA 2025 (Scheduled), the AEA ASSA 2026 (Scheduled)]

This paper analyzes the impact of several exogenous shocks on households’ disagreement in inflation expectations and nonlinearities in the response of inflation disagreement that are triggered by the level of inflation or the level of the unemployment rate. Using monthly data from the University of Michigan’s Survey of Consumers from January 1985 to December 2024, I examine the response of disagreement in inflation expectations, measured by the interquartile range and standard deviation of one-year-ahead inflation expectations. I find that disagreement responds significantly, though temporarily, to various oil shocks and economic policy uncertainty shocks. The nonlinear specification shows that the responses of disagreement depend on the level of inflation and the state of the business cycle. Specifically, disagreement tends to be more responsive under low-inflation and low-unemployment regimes compared to cases when inflation or unemployment are high. A robustness check that uses a residualized measure of disagreement that controls for observable household characteristics confirms the main findings. However, economic policy uncertainty shocks generate more persistent effects on disagreement in the residualized model, especially in low-state regimes.

Estimated Output Gap in a Wage-Inflation Expectations Model (with Prajyna Barua Soni, Irina Panovska, Srikanth Ramamurthy)

[Conference Presentation: the SEM 2024, the SEA 2023, the CFE 2022]

We study how incorporating adaptive learning-based inflation expectations for price and wage inflation can improve the performance of Unobserved Components (UC) models both when it comes to inference about the output gap and when it comes to forecasting performance. We incorporate learning-based expectations and bivariate feedback in the learning dynamics for wage and price inflation, and we augment a conventional reduced-form UC model for output and unemployment with this bivariate learning process. Our model directly integrates the expectations dynamics of the Hybrid New Keynesian Philips Curve while also retaining the appealing statistical features of the UC framework, allowing us to extract information about the output gap. Three interesting sets of results stand out. First, while the perceived persistence of inflation fell during the early stages of the pandemic, it increased sharply and substantially during the period 2021Q2-2022Q2. Second, the estimated output gap started decreasing in mid-2019, decreased sharply during the early stages of the pandemic, and bounced back rapidly. Finally, including information about the output gap and about the price and wage inflation expectations process helps improve macroeconomic forecasts.
