We study the impact of mandatory calorie posting on consumers' purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers' food choices--there is almost no change in purchases of...

The 2010 Patient Protection and Affordable Care Act (ACA) introduced a mandate requiring chain restaurants to post calorie counts on menus and menu boards. This paper investigates whether and why calorie posting laws work. To do so, we develop a model of calories consumed that highlights two...

Owners of intellectual property or mere sponsors of an idea (e.g., authors, security issuers, sponsors of standards) often need to persuade potential buyers or adopters of the worth of their property or idea. To this purpose, they often resort to more or less independent certifiers. This paper...

Quality certification programs help consumers to identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK's online marketplace, we study how certification's impact on consumer demand varies with market- and seller-level attributes, exploiting...

We study the effects of receipts that include personalized ordering suggestions designed to reduce fat and calorie consumption on purchasing behavior at a restaurant chain. We find that customers, in the aggregate, made most of the item substitutions that were encouraged by the messages, such as...

We evaluate the effectiveness of energy efficiency labeling in guiding household decisions. Using a carefully designed choice experiment with alternative labels, we disentangle the relative importance of different types of information and intertemporal behavior (i.e., discounting) in guiding...

This essay reviews the theoretical and empirical literature on quality disclosure and certification. After comparing quality disclosure with other quality assurance mechanisms and describing a brief history of quality disclosure, we address three key theoretical issues: (i) Why don't sellers...
