1Lecture 12 Food Consumption and Labeling
Policies
- Kristin Kiesel
- UC Berkeley
2Motivation and Outline
- Information provision as alternative policy tool
to address externalities - Organic labeling
- Nutritional labeling and the food guide pyramid
- (non-biotech or non-GMO labeling)
- Policy context as determinant of success
- Food consumption
- Interdependencies with marketing efforts and
media coverage
3Objective
- Does availability of information insure that it
will be incorporated into consumer behavior? - If not, which aspects of informational changes
under labeling regulations are most effective in
altering consumer behavior? - A better understanding of the interplay between
regulation, media coverage, and product
marketing helps determine which regulatory tools
best serve consumers interest and policy
objectives at the same time
4Food Consumption
- For any policy evaluation, its history and
context need to be well understood - Traditional analysis of food demand
- Two influential models in analysis of
additional aspects - Additional determinants of individual food
consumption - General trends in food consumption
-
5Traditional Analysis of Food Demand
- Food demand depends on
- quality (nutritional value, taste, food safety)
- prices and income
- Increase in prices lead to reduction in
consumption - (law of demand)
- Impacts of income on consumption
- Luxury goods increase in income results in more
than proportional increase in consumption (filet
mignon) - Normal good increase in income results in less
than proportional increase in consumption
(cheese) - Inferior good increase in income results in
reduction in consumption (canned peas) - Illustration 5 increase in income will increase
consumption of filet mignon by 8, increase in
consumption of cheese by 4, and reduce canned
peas consumption by 7
6Traditional Analysis of Food Demand (cont.)
- The demand for a specific food product depends on
the price of other food products - Complements (peanut butter and jelly, bread and
butter) - increase in price of one will reduce the demand
for the other (higher peanut butter price will
reduce demand for jam) - Substitutes (butter and margarine, corn syrup
and sugar) - increase in price of one will increase the
demand for the other (higher butter prices will
increase the demand for margarine).
7Traditional Analysis of Food Demand (cont.)
- Seasonality and availability constraints
- Turkey demand surges at Thanksgiving
- Prices and quality of fruits and vegetables
- Additionally, most people shop at a particular
supermarket, limiting their range to the
assortment of that store
Prices of fruits and vegetables are lowest in the
midst of season when the quality is best
price
Middle of season
Time
8Two Influential Theoretical Models
- Household production function (Becker 1965,
Lancaster 1966) - Logic of production functions applied to consumer
side products are purchased in the market as
inputs, and utility is derived from attributes
after some transformation (e.g. labor, time) - Important concept of opportunity costs of time
- Hedonic price functions (Rosen 1974)
- Allows consideration of differentiated goods
through a value (price) function that depends on
specific amount of product characteristics
9Household Production Models A Modern Approach to
Food Demand
- Families purchase food products, and use
equipment and time to produce meals - (eggs versus omelet)
- The demand for food depends on household
composition and labor market considerations - Increased participation of women in labor force
lead to increased demand for - Precut meats and salads
- Ready to eat meals
- Food outside of home (restaurants)
10Hedonic Models Whats in the price of food?
- Hedonic price function a product price is the
sum of monetary valuation of each of its
attributes - Price of food bundles payments for
- Health (nutritional content)
- Quality and taste
- Convenience
- Example a 15 entry at a restaurant reflects
- 5 nutritional components (calories, protein,
vitamins, etc.), - 4 quality and taste (specific preparation,
seasoning, etc. ), - 3 convenience, and 3 atmosphere
- Two main trends increased willingness to pay for
convenience and taste (quality)
11The Power of the Consumer
- Only about 17 of new food products introduced in
retail market succeed - Costs of failure are high as introduction of a
new product nationally is 5-10 million or more
(Asp 1999) - Heterogeneity in preferences as important
- factor of food consumption
- Implications for marketing, labeling,
- certification, and technology adoption
- Factors affecting consumer demand beyond
- classical determinants not well understood
- and important area of research
- Food consumption as possible political statement
and new level of consumer-producer discourse
(Puis 2000)
12Lifestyle, Family Dynamics, and Cooking Skills
- Food habits (cultural standardized set of
behavior) and lifestyle as determinants of food
demand - Family dynamics
- Women tend to have more control over food choices
- The cook and the grocery shopper determine food
purchases Less convenience food is purchased
when the shopper is not the cook (when wife cooks
and the husband shops, he is less likely to buy
precut chicken than when she shops) - Eating habits of children in household influence
food choices (e.g. picky eater) - More skilled and appreciative cooks will buy less
pre-processed food like precut vegetables (e.g.
slow food movement)
13Beliefs, Attitudes, and Perceptions
- Religious and ethical beliefs, social and
environmental considerations can further
establish norms and constraints in food
consumption - Friday penance by Catholics (required meat
abstinence) after announcement by Pope Paul VI
(1966) that it is not binding, Friday fish
consumption declined drastically - Kosher food for Jewish, and halal meats for
Muslims - Vegetarian, vegan eating habits
- non-biotech and organic preferences
- Economic relevance
- Better understanding of consumer behavior
- Policy implications
14Established and Emerging Food Trends
- Convenient foods
- Fresh foods
- Ethnic foods
- Fusion foods
- Prepared home meal replacements
- Food mixtures
- Natural and organic food
- Health promoting foods (e.g. probiotics)
- Physical performance foods
15Regulatory Settings
- Two types of informational policies
- 1. Reactive policies In response to food trends
- Regulation to ensure consistent and truthful
information provision to consumer - Development of standards, rules and certification
(e.g. National Organic Program) - Beliefs and perceptions can be invoked and
strengthened by regulation - 2. Proactive policies Aimed at influencing food
trends - Regulation to provide information aimed at
directly affecting consumption patterns (e.g.
Nutritional Labeling and Food Guide Pyramid) - Attitudes and beliefs affect regulatory goals
16The National Organic Program (NOP)
- The U.S. organic market is projected to reach a
value of 30.7 billion by 2007, with a five-year
compound annual growth rate of 21.4 percent
between 2002 and 2007, (Organic Trade
Association) - One of the fastest-growing categories in food
business. - Nearly two thirds of U.S. Consumers bought
organic foods and beverages in 2005 (Consumer
Reports 2006, CR). - Organic products sell at a significant price
premium compared to their conventional
counterparts at 50 on average which prices often
doubling for milk and meats (CR 2006). - Organic Foods Production Act (OFPA) of 1990
required the USDA to develop a national standard
to assure consumers that agricultural products
marketed as organic meet consistent, uniform
standards - National organic standard and labeling
regulations for organically produced agricultural
products became effective in October 2002
17What is Organic Food?
- Definition (from National Organic Program
website, USDA) - Organic food is produced by farmers who
emphasize the use of renewable resources and the
conservation of soil and water to enhance
environmental quality for future generations.
Organic meat, poultry, eggs, and dairy products
come from animals that are given no antibiotics
or growth hormones. Organic food is produced
without using most conventional pesticides
fertilizers made with synthetic ingredients or
sewage sludge bioengineering or ionizing
radiation. Before a product can be labeled
"organic," a Government-approved certifier
inspects the farm where the food is grown to make
sure the farmer is following all the rules
necessary to meet USDA organic standards.
Companies that handle or process organic food
before it gets to your local - supermarket or restaurant must be certified
too. -
- Addresses positive environmental externalities
of - consuming organic food
18What is Organic Food? (cont.)
- USDA makes no claims that organically produced
food is safer or more nutritious than
conventionally produced food - Little or no scientific evidence on enhanced
nutritional value or health benefits (e.g.
Williams 2000) - In many studies top motives to buy organic are
taste, food safety and health concerns - Example organic dairy (McEachern and McClean
2002) purchase motivations - Improved taste (30)
- Food safety (24)
- Health benefits (17)
- Environmental concern (16)
- Ethical concerns (10)
- These perceptions might be reinforced by
USDA-label - Attracts attention to attribute
- Might suggest potential benefits or risks that
make it worth pointing out - Acts as an anchor and/or adds intrinsic value
(Kahneman and Twersky 2000, Ariely , Loewenstein
and Prelec 2003)
19Cost-Benefit Analysis of the NOP
- How do we go about evaluating the NOP?
- 1. How do we measure the costs?
- 2. How do we measure the benefits?
- How do we account for heterogeneous preferences?
- What if consumers choose organic products for the
wrong reason? - How do we account for different informational
aspects such as media coverage, marketing
efforts, and actual - labeling change?
- Do we see growth because of changes in
regulations or were - changes in regulations a result of growth ?
20My research Milk is Milk?
- 1. How does the implementation of the NOP and
changes in information provision affect consumer
preferences for organically produced milk? - 2. Do these effects vary across consumer
segments differentiated by both heterogeneous
preferences and heterogeneity in prior knowledge
and information costs? - 3. How much did consumer benefit from these
regulatory changes and how are these benefits
distributed across consumer segments? - 4. How do changes in purchase behavior relate to
different aspects of the information changes,
such as prior media coverage of regulatory
changes and actual appearance of the USDA organic
seal on milk containers? - Preliminary results indicate a increased
probability of organic milk purchase after the
appearance of the USDA seal. - The hedonic price function approach as well as
simulations within discrete choice models suggest
that consumers value the changes in labeling
regulations. - A positive relation between organic milk sales
relative to total milk sales and media coverage
prior to the appearance of the USDA organic seal
is detected.
21Nutritional Labeling and the Food Guide Pyramid
- What is the externality addressed with
these regulations? - Nutrition, Labeling, and Education Act of 1990
gave FDA authority to require nutrition labeling
of most foods - In April 1992 USDAs Eating right pyramid
- released after a year of controversy and
- 855.000 additional spending
- In February 2006 USDA unveils revised food
- pyramid
22The Food Pyramid of to a Bad Start
- In April 199, printing of the eating right
pyramid was blocked due to opposition from meat
and dairy industry - final version preferred version by meat and
- dairy industry (non-hierarchical)
- Media coverage of the political background paints
a picture of politics versus sciences
23Related Research Findings
- Purchase behavior changed, but purchase of
healthy products increased only in some
categories (e.g. Teisl, Bockstael, and Levy 2001) - Nutritional labeling has reduced
- and narrowed focus on nutrition in
- advertisement
- (e.g. Ippolito and Pappalardo 2002)
24Back to Food Consumption
25Conclusions
- Some critics say that organic labels takes
attention away from health problems related to
obesity and other nutritional issues - But, evaluation of organic labeling might provide
a better understanding of successful aspects of
informational regulation and ultimately allow to
design better health and environmental related
informational policies
