Abstract “Hard discounters” are retail formats that set retail food prices even lower than existing discount formats, such as Walmart and Target. Offering limited assortments and focusing on store-brands, these formats promise to change the competitive landscape of food retailing. In this paper, we study the effect of entry of one hard-discount format on markups earned by existing retail stores, focusing on several important grocery markets across the Eastern U.S. Focusing on establishment-level profitability, we estimate store-level markups using the production-side approach of De Loecker and Warzynski (Am Econ Rev 102(6):2437–2471). We find that hard-discounter entry reduced markups for incumbment retailers by 7.3% relative to markups in non-entry markets. These results indicate that the net effect of hard-discounter entry reduces the overall level of store profitability—despite the somewhat higher sales realized by incumbent retailers.
