How Do Supply Chain Pressures Affect Monetary Policy Transmission? (Job Market Paper)
The COVID-19 pandemic and geopolitical shocks have severely strained global supply chains and contributed to persistent inflation worldwide. Although supply chain disruptions have been widely discussed in policy circles since the pandemic, their role in monetary policy transmission remains understudied, largely because firm-level stress is hard to measure using conventional data. I address this gap by developing a firm-level indicator using natural language processing of earnings call transcripts. Empirically, I show that after expansionary monetary shocks, constrained firms invest more in capital and raise prices more aggressively than unconstrained peers. I incorporate these findings into a New Keynesian general equilibrium model in which supply chain frictions imply that not all ordered inputs arrive on time or in usable condition. Model simulations align with the evidence and highlight a substitution mechanism: following an expansionary shock, firms substitute away from constrained inputs toward capital to expand production and meet higher demand. Together, the results show that stressed supply chains alter the transmission of monetary policy and pose a trade-off for policymakers: expansionary shocks can boost long-run productive capacity via input-to-capital substitution, but at the cost of a short-run inflation overshoot.

The Effect of U.S. Monetary Policy on Foreign Firms: Does Debt Maturity Matter? [SSRN] (Revise and Resubmit, Journal of International Economics)
Joint work with Sebastiao Oliveira and Jay Rafi
We provide novel evidence that corporate debt maturity plays an important role in the transmission of U.S. monetary policy to foreign firms. Using an identification strategy that explores the ex-ante maturity structure of long-term debt to predict firms’ financial position in a given year, we show that the effect of U.S. monetary policy shocks on foreign firms is amplified by financing constraints. After a contractionary shock, financial conditions in foreign countries become tighter, and firms with a high proportion of long-term debt maturing right after the shock significantly decrease investment and sales. We find that firms in emerging economies are much more affected by these shocks compared to those in advanced economies, and the amplification effect of U.S. monetary policy shocks by financing constraints is present only in emerging economies.

Interpreting Monetary Policy Surprises: Does Central Bank Credibility Matter? [SSRN] (Submitted, Review of Finance)
Joint work with Sebastiao Oliveira
This paper uses the Brazilian central bank’s loss of credibility episode under President Dilma Rousseff’s administration (2011-2014) to provide novel evidence that professional forecasters interpret monetary policy surprises differently depending on the level of central bank’s credibility. With credibility, they understand a monetary policy surprise as a monetary policy shock and decrease their inflation expectations 12 months ahead by -0.25%. With no credibility, they interpret it as an information effect and increase their inflation expectations by 0.57%. We also document three stylized facts: noneffective inflation target tolerance intervals during periods of low credibility, a loss of credibility has a long-lasting impact on long-term inflation expectations, and significantly higher disagreement among inflation expectations during low credibility periods.

Mining the Gap: Extracting Firms' Inflation Expectations from Earnings Call [IMF Working Paper]
Joint work with with Silvia Albrizio and Allan Dizioli
Using a novel approach involving natural language processing (NLP) algorithms, we construct a new cross-country index of firms' inflation expectations from earnings call transcripts. Our index has a high correlation with existing survey-based measures of firms' inflation expectations, it is robust to external validation tests and is built using a new method that outperforms other NLP algorithms. In an application of our index to United States, we uncover some facts related to firm's inflation expectations. We show that higher expected inflation translates into future inflation. Going into the firms level dimension of our index, we show departures from a rational framework in firms' inflation expectations and that firms' attention to the central enhances monetary policy effectiveness.

Breaking the Chain: Supply Chain Disruptions and Terms-of-Trade Amplification Draft Link
Joint work with Flavio Rodrigues
This paper examines how supply chain disruptions amplify the macroeconomic consequences of terms-of-trade shocks in open economies. We develop a parsimonious small-open-economy model in which supply chain bottlenecks reduce the efficiency of imported goods. Leveraging a novel, country-specific measure of supply chain pressures constructed from textual analysis, we find that periods of elevated strain magnify the adverse effects of terms-of-trade deteriorations. In such episodes, output declines are steeper, unemployment rises more sharply, real exchange rate depreciation is greater, and inflation accelerates relative to low-pressure periods. The empirical evidence closely aligns with the model’s predictions. Taken together, these results highlight the critical role of supply chain conditions in shaping the transmission of external shocks and suggest that conventional stabilization policies may be less effective when such disruptions are acute.

Attention, please! Listening to the central bank in uncertain times (AEA Papers and Proceedings, 2025, Vol. 115)
Joint work with with Silvia Albrizio, Allan Dizioli and Yifan Zhang
This paper investigates how firms' attention to central banks influences monetary policy transmission under varying macroeconomic uncertainty. The paper utilizes the earnings calls-based firm inflation expectations index and a novel attention indicator at the firm level in the empirical analysis. Attention amplifies the impact of monetary policy in low-uncertainty environments, but this effect dissipates during periods of high uncertainty. An extended rational inattention model with a central bank signal explains these findings. The model predicts that, in high-uncertainty environments, firms are already well-informed, and there is less new information from the Central Bank.
Text-to-Insight: An NLP Pipeline for Quantifying Open-Ended Survey Responses
Joint work with with Shihan Xie
Open-ended survey questions offer unique insights into nuanced economic beliefs but remain challenging to analyze due to costly and subjective manual coding. We introduce a practical, reproducible natural language processing (NLP) framework designed specifically for systematically analyzing open-ended survey responses. Demonstrated through two applications, we benchmark transformer-based models and large language models, providing clear guidance on selecting appropriate NLP strategies. Our method significantly lowers barriers to analyzing qualitative data, empowering economists to derive robust quantitative insights efficiently.
Individual Uncertainty and Attention to Macro Conditions
Joint work with with Shihan Xie
This paper explores the relationship between individual uncertainty about economic conditions and households' attentiveness to the macroeconomy. Drawing on household-level data, we establish stylized facts that reveal two opposite effects of uncertainty, depending on an individual's employment status. For individuals with jobs, increased income uncertainty leads to greater attentiveness to macroeconomic situations, resulting in lower forecast errors of future inflation. This finding suggests a precautionary motive for attentiveness. Conversely, for individuals experiencing extreme economic difficulty, such as job loss, attention to macroeconomic conditions is crowded out by the need to devote time to job search. These effects are amplified during recessions. Our results contribute to a better understanding of how individual uncertainty and macroeconomic conditions interact and have implications for policymakers seeking to support households during times of economic difficulty.
The literature offers no consensus on whether variations in consumer expectations influence consumption. Using households’ political preferences as an instrument for shifts in sentiment, this paper finds asymmetric and significant changes in macroeconomic expectations around U.S. presidential elections, with no corresponding increase in willingness to spend. Analysis of expectations for personal economic conditions, employment status, income growth, and credit availability, shows no significant changes. The results suggest that partisan-driven shifts in macroeconomic expectations do not reflect accurate personal forecasts and, therefore, fail to translate into consumer behavior.
