THERE'S NO SUCH THING AS QUALITY:

Smart Money Buys Brand X (Cass R. Sunstein, 7/13/14, Bloomberg View)

To test whether a lack of information is responsible for consumers' choices, Bronnenberg and his co-authors compared a range of consumers who shop in the same markets and chain stores during the same time periods. They used both indirect and direct measures of how well-informed the shoppers were about headache remedies. The indirect measures included occupation and education. The direct measures came from shoppers' responses to questions about the active ingredients in headache remedies. There was a close connection between the indirect and direct measures: The average person accurately answered the ingredient question 59 percent of the time, but that figure rose to 85 percent for registered nurses and to 89 percent for pharmacists.

Using purchase data on more than 77 million shopping trips from 2004 to 2011, the authors matched consumers' actual choices to their knowledge and professions. Pharmacists bought national brands only 8.5 percent of the time, while the average consumer bought them 26 percent of the time. People lacking a college education were especially likely to buy national brands. On the other hand, health-care professionals -- including nurses and doctors -- were more likely to buy store brands than lawyers, who don't have relevant expertise.

In the case of pantry staples (salt, sugar, baking soda and the like), national brands accounted for 40 percent of total sales volume. But among chefs, the share dropped to just 23 percent -- the smallest for any other occupation.
