Slotting allowances are payments made by manufacturers to obtain retail shelf space. They are widespread in the grocery industry and a concern to antitrust authorities. A popular view is that slotting allowances arise because there are more products than retailers can profitably carry given their shelf space. We show that the causality can also go the other way: the scarcity of shelf space may in part be due to the feasibility of slotting allowances. It follows that slotting allowances can be anticompetitive even if they have no effect on retail prices.

What to Eat is a classic—"the perfect guidebook to help navigate through the confusion of which foods are good for us" (USA Today). Since its publication in 2006, Marion Nestle's What to Eat has become the definitive guide to making healthy and informed choices about food. Praised as "radiant with maxims to live by" in The New York Times Book Review and "accessible, reliable and comprehensive" in The Washington Post, What to Eat is an indispensable resource, packed with important information and useful advice from the acclaimed nutritionist who "has become to the food industry what . . . Ralph Nader [was] to the automobile industry" (St. Louis Post-Dispatch). How we choose which foods to eat is growing more complicated by the day, and the straightforward, practical approach of What to Eat has been praised as welcome relief. As Nestle takes us through each supermarket section—produce, dairy, meat, fish—she explains the issues, cutting through foodie jargon and complicated nutrition labels, and debunking the misleading health claims made by big food companies. With Nestle as our guide, we are shown how to make wise food choices—and are inspired to eat sensibly and nutritiously.
