Does food marketing need to make us fat? A review and solutions

Food marketing is often singled out as the leading cause of the obesity epidemic. The present review examines current food marketing practices to determine how exactly they may be influencing food intake, and how food marketers could meet their business objectives while helping people eat healthier. Particular attention is paid to the insights provided by recently published studies in the areas of marketing and consumer research, and those insights are integrated with findings from studies in nutrition and related disciplines. The review begins with an examination of the multiple ways in which 1) food pricing strategies and 2) marketing communication (including branding and food claims) bias food consumption. It then describes the effects of newer and less conspicuous marketing actions, focusing on 3) packaging (including the effects of package design and package-based claims) and 4) the eating environment (including the availability, salience, and convenience of food). Throughout, this review underscores the promising opportunities that food manufacturers and retailers have to make profitable "win-win" adjustments to help consumers eat better.

Nutrition Labeling to Prevent Obesity: Reviewing the Evidence from Europe

Overweight and obesity are major public health problems in the European Union (EU). Providing nutrition information on foods and menus is considered a relevant means to guide consumers toward more healthful food choices, in part characterized by adequate energy intakes to achieve and maintain a healthy body weight. Various formats of back-of-pack and front-of-pack nutrition labeling can currently be found across the EU, with varying levels of penetration. Experimental studies show that consumers are reasonably able to understand and use the different systems to identify more healthful food products from given choice sets. However, European studies assessing the impact of nutrition labeling on actual dietary intake are scarce, and no real-life evidence exists linking nutrition label use with measured changes in body weight. This review summarizes how European consumers respond to nutrition labels when shopping for food or eating out of home, considering evidence published between 2007 and mid-March 2012.

The financial consequences of too many men: sex ratio effects on saving, borrowing, and spending

The ratio of males to females in a population is an important factor in determining behavior in animals. We propose that sex ratio also has pervasive effects in humans, such as by influencing economic decisions. Using both historical data and experiments, we examined how sex ratio influences saving, borrowing, and spending in the United States. Findings show that male-biased sex ratios (an abundance of men) lead men to discount the future and desire immediate rewards. Male-biased sex ratios decreased men's desire to save for the future and increased their willingness to incur debt for immediate expenditures. Sex ratio appears to influence behavior by increasing the intensity of same-sex competition for mates. Accordingly, a scarcity of women led people to expect men to spend more money during courtship, such as by paying more for engagement rings. These findings demonstrate experimentally that sex ratio influences human decision making in ways consistent with evolutionary biological theory. Implications for sex ratio effects across cultures are discussed.

Self-perceived Age and Attitudes Toward Marketing of Older Consumers in China

Understanding consumer psychological characteristics and their impact on consumer behavior is an important foundation for business marketing strategies. Self-perceived age has a great impact on older consumers' behavior. This article defines the gray market in China, investigates the factors that affect the differences between older consumers' self-perceived age and life age, and analyzes the influence of self-perceived age on older Chinese consumers' behavior. In this study, 1,120 older consumers were randomly selected from six cities in China. Findings show that over half of the respondents feel younger than their actual life age. Related marketing strategies are discussed.

Brand placement and consumer choice: an in-store experiment

An in-store experiment was performed to investigate the effects of shelf placement (high, middle, low) on consumers' purchases of potato chips. Placement of potato chips on the middle shelf was associated with the highest percentage of purchases. The results confirm the importance of item placement as a factor in consumers' buying behavior.

The Market Response to the Sioux City DC-10 Crash

The 1989 DC-10 crash at Sioux City, Iowa presented a rare instance in which a potential threat to safety was both (i) intensely publicized over a short period and (ii) also amenable to the unobtrusive measurement of the market reaction it evoked. As such, it allowed a useful case study of the extent and duration of behavior change caused by a frightening event. Using reservations data from travel agencies in five states, this paper estimates the short-term effects of the Sioux City crash on passenger willingness to fly the DC-10. The data suggest that, in the first few weeks after the crash, more than one third of travelers who would normally have booked DC-10 flights chose instead to fly other aircraft. Within 2 months of the disaster, however, DC-10 bookings rebounded to within 10% of the level that would have been expected had the Sioux City crash not occurred. At no time, apparently, did the airlines that operate DC-10s use their "yield-management" computer pricing systems unofficially to lower DC-10 fares relative to those on other types of plane.
