Who’s Ready to Spend? Constrained Consumption across the Income Distribution
Spending on goods and services that were constrained during the pandemic is expected to grow at a fast pace as the economy reopens. In this post, we look at detailed spending data to track which consumption categories were the most constrained by the pandemic due to social distancing. We find that, in 2019, high-income households typically spent relatively more on these pandemic-constrained goods and services. Our findings suggest that these consumers may have strongly reduced consumption during the pandemic and will likely play a crucial role in unleashing pent-up demand when pandemic ...

An Update on the Health of the U.S. Consumer
The strength of consumer spending so far this year has surprised most private forecasters. In this post, we examine the factors behind this strength and the implications for consumption in the coming quarters. First, we revisit the measurement of “excess savings” that households have accumulated since 2020, finding that the estimates of remaining excess savings are very sensitive to assumptions about measurement, estimation period, and trend type, which renders them less useful. We thus broaden the discussion to other aspects of the household balance sheet. Using data from the New York ...

A Turning Point in Wage Growth?
The surge in wage growth experienced by the U.S. economy over the past two years is showing some tentative signs of moderation. In this post, we take a closer look at the underlying data by estimating a model designed to isolate the persistent component—or trend—of wage growth. Our central finding is that this trend may have peaked in early 2022, having experienced an earlier rise and subsequent moderation that were broad-based across sectors. We also find that wage growth seems to be moderating more slowly than the trend in services inflation.

Nonlinear Firm Dynamics
This paper presents empirical evidence on the nature of idiosyncratic shocks to firms and discusses its role for firm behavior and aggregate fluctuations. We document that firm-level sales and productivity are hit by heavy-tailed shocks and follow a nonlinear stochastic process, thus departing from the canonical linear. We estimate a state-of-the-art model to flexibly capture the rich dynamics uncovered in the data and characterize the drivers of nonlinear persistence and non-Gaussian shocks. We show that these features are crucial to get empirically plausible volatility and persistence of ...

How Large Are Inflation Revisions? The Difficulty of Monitoring Prices in Real Time
With prices quickly going up after the COVID-19 pandemic, inflation releases have rarely been as present in the public debate as in recent years. However, since inflation estimates are frequently revised, how precise are the real-time data releases? In this Liberty Street Economics post, we investigate the size and nature of revisions to inflation. We find that inflation estimates for a given month can change substantially as subsequent data vintages are released. As an example, consider March 2009. With the economy contracting amid the Global Financial Crisis, the twelve-month inflation rate ...

Latent Heterogeneity in the Marginal Propensity to Consume
We estimate the unconditional distribution of the marginal propensity to consume (MPC) using clustering regression and the 2008 stimulus payments. Since we do not measure heterogeneity as the variation of MPCs with observables, we can recover the full distribution of MPCs. Households spent at least one quarter of the rebate, and individual households used rebates for different goods. While many observables are individually correlated with our estimated MPCs, these relationships disappear when tested jointly, except for nonsalary income and the average propensity to consume. Household ...

How Did State Reopenings Affect Small Businesses?
In our previous post, we looked at the effects that the reopening of state economies across the United States has had on consumer spending. We found a significant effect of reopening, especially regarding spending in restaurants and bars as well as in the healthcare sector. In this companion post, we focus specifically on small businesses, using two different sources of high-frequency data, and we employ a methodology similar to that of our previous post to study the effects of reopening on small business activity along various dimensions. Our results indicate that, much like for consumer ...

Consumption Sensitivity of Uncertain Households
Uncertainty is a key component of everyday economic decisions of consumers and, perhaps not surprisingly, it plays a central role in economic models. According to economic theory, forward-looking consumers rely on their expectations and perceived uncertainty when making economic decisions. Nevertheless, measuring the uncertainty that households actually perceive, and how it affects consumer behavior, is challenging. The probabilistic nature of the Survey of Consumer Expectations enables us to make progress on this subject and to construct household-specific time-varying uncertainty. In our ...

Subjective Uncertainty and the Marginal Propensity to Consume
Earnings uncertainty is central to most heterogeneous-household models. Yet, there is surprisingly little evidence on how subjective uncertainty is related to consumption behavior. Using unique data from the Survey of Consumer Expectations, we show that the marginal propensity to consume (MPC) is increasing and concave in individual specific earnings growth uncertainty. In the workhorse consumption–savings model, augmented with risk heterogeneity, MPCs decline with earnings uncertainty, contrary to the empirical evidence. We pinpoint which mechanisms, central to the model, create this ...

Stimulus through Insurance: The Marginal Propensity to Repay Debt
Using detailed micro data, we document that households often use “stimulus” checks to pay down debt, especially those with low net wealth-to-income ratios. To rationalize these patterns, we introduce a borrowing price schedule into an otherwise standard incomplete markets model. Because interest rates rise with debt, borrowers have increasingly larger incentives to use an additional dollar to reduce debt service payments rather than consume. Using our calibrated model, we then study whether and how this marginal propensity to repay debt (MPRD) alters the aggregate implications of fiscal ...
