We study how within-store price variation changes with inflation, and whether households exploit it to attenuate the inflation burden. We use micro price data for food products sold by 91 large multi-channel retailers in ten countries between 2018 and 2024. Measuring unit prices within narrowly defined product categories, we analyze two key sources of variation in prices within a store: temporary price discounts and differences across similar products. Price changes associated with discounts grew at a much lower average rate than regular prices, helping to mitigate the inflation burden. By contrast, cheapflation—a faster rise in prices of cheaper goods relative to prices of more expensive varieties of the same good—exacerbated it. Using Canadian Homescan Panel Data, we estimate that spending on discounts reduced the change in the average unit price by 4.1 percentage points, but expenditure switching to cheaper brands raised it by 2.8 percentage points.

He also co-founded PriceStats in 2011, the leading private source of inflation and PPP statistics in over 25 countries.
Cavallo earned a Bachelor of Science in Economics with summa cum laude from the Universidad of San Andres in Buenos Aires in 2000.

NBER Working Paper #32626
We study how within-store price variation changes with inflation, and whether households exploit it to attenuate the inflation burden. We use micro price data for food products sold by 91 large multi-channel retailers in ten countries between 2018 and 2024. Measuring unit prices within narrowly defined product categories, we analyze two key sources of variation in prices within a store: temporary price discounts and differences across similar products. Price changes associated with discounts grew at a much lower average rate than regular prices, helping to mitigate the inflation burden. By contrast, cheapflation—a faster rise in prices of cheaper goods relative to prices of more expensive varieties of the same good—exacerbated it. Using Canadian Homescan Panel Data, we estimate that spending on discounts reduced the change in the average unit price by 4.1 percentage points, but expenditure switching to cheaper brands raised it by 2.8 percentage points.
American Economic Review - Insights (forthcoming)We leverage the inflation upswing of 2022 and various granular datasets to identify robust price-setting patterns following a large supply shock. We show that the frequency of price changes increases dramatically after a large shock. We set up a parsimonious New Keynesian model and calibrate it to fit the steady-state data before the shock. The model features a significant component of state-dependent decisions, implying that large cost shocks incite firms to react more swiftly than usual, resulting in a rapid pass-through to prices--large shocks travel fast. Understanding this feature is crucial for interpreting recent inflation dynamics.NBER Working Paper 29437We use data from a large web-based job platform to study how the price of remote work is determined in a globalized labor market. In the platform, workers located around the world compete for jobs that can be done remotely. We document that, despite the global nature of the marketplace, the worker's country accounts for almost a third of the variance in remote wages. The observed wage differences are strongly correlated to the GDP per capita in the worker's location. This correlation is not accounted for by differences in workers' observable characteristics, occupations, or differences in the employers' locations. Instead, data on wage-histories indicate that remote wages are partly determined by the conditions that workers face in their local labor markets. We also document that, as with internationally traded goods, remote wages expressed in local currency move strongly with the dollar exchange rate of the worker's country, and are highly sensitive to changes in the wages of foreign competitors.Journal of International Economics (forthcoming)We use a detailed micro dataset on product availability to construct a direct high-frequency measure of consumer product shortages during the 2020--2022 pandemic. We document a widespread multi-fold rise in shortages in nearly all sectors early in the pandemic. Over time, the composition of shortages evolved from many temporary stockouts to mostly discontinued products, concentrated in fewer sectors. We show that unexpected product shortages have significant inflationary effects within three months. These effects are larger and more persistent for imported goods and import-intensive sectors. We develop a model of inventories in a sector facing both demand and cost disturbances, and use the observed joint dynamics of stockouts and prices to show that these effects can be associated with elevated costs of replenishing inventories and higher exposure to trade.
