摘要
This article analyzes household food purchase behavior in response to changes in product package size. In particular, we exploit food manufacturer package downsizing strategy and design a difference-in-difference analysis to track shifts in household purchase volume in affected and comparison product groups before and after package size changes. We use UPC-level purchase data from a panel of households over a seven-year period for analysis. Our empirical approach overcomes two important limitations of the extant literature: it (i) accounts for determinants of purchase behavior and (ii) produces results that elucidate the long-term effects of package size changes. The main finding is that, on average, smaller package size significantly reduces household purchase volume, which indicates a positive correlation between package size and food-at-home consumption. The results also show that downsizing does not have a significant effect on the purchase volume of non-downsized products and on the number of packages purchased. The implications of the results for policy and potential interventions are discussed.
