Although it is commonly assumed that consumers eat more and find food to be more attractive when hungry, surprisingly little research has looked at how robust this effect might be and what could moderate it. Building on theories of hunger and self-control, this research examines which types of foods (hedonic or utilitarian) are more attractive and likely to be consumed by hungry consumers. Across a series of six experiments I find that when hungry and under reduced cognitive capacity, consumers find hedonic foods more attractive and consume them in larger quantities. However, when hungry and with high cognitive capacity, consumers have the ability to engage in counteractive self-control, thus limiting both the attractiveness and consumption of hedonic food items. Furthermore, I find that hunger is not likely to influence the attractiveness of utilitarian foods, but is likely to increase the consumption of these foods, regardless of cognitive capacity.

This research explores the influence of brand and shelf display cues on consumer preferences for products that appear to be in scarce supply. In so doing, I develop a theoretical model of how scarcity operates in the retail environment, identifying when it increases purchase intentions, when it decreases purchase intentions, and the underlying mechanisms driving these outcomes. Across a series of five studies, I find that when consumers infer that products are scarce due to popularity, they are more likely to buy these products, but only when the products are unfamiliar nonfood brands. I also find that scarce products are less likely to be purchased when they are familiar food brands. In addition, the price of the product is an important moderator of these effects, as price further influences perceptions about the popularity of the product.
