2Introduction
- By 2010, 21 farmers markets throughout the
Boston metropolitan area participated in the BBB
program and the usage of SNAP (41,402.28) along
with BBB matches (36,409.46) combined for a
total of 77,811.74 in sales- a 387 increase
over the previous summer. - Representing 28.5 of total Boston sales, the ten
FM located in Dorchester and Roxbury reported a
total of 21,699.58 in combined SNAP/BBB sales
(The Food Project, preliminary report, 2011). - BUT, there remains a widespread perception that
farmers market produce is more expensive than
conventional supermarket produce. This
uninformed perception is a barrier to the
attendance of price-sensitive shoppers at
farmers markets.
3Relative Cost of Direct Retail
- Problems with previous research did not devise
plan to handle multi-leveled inconsistency of
produce, combined produce into market basket,
short time frame ignored effects of seasonality
and volume. - Demonstrated need for a replicable methodology
for comparing produce prices at conventional
grocery outlets with those at direct retail
outlets - Must be neighborhood-specific, include strategies
that account for hard to measure effects of
seasonality and quality

4Observational Study
- Objective
- Clarify perception that farmers market produce is
more expensive than conventional market produce
in order to accurately educate communities about
the local affordability of healthy food inform
the efforts of community groups, policy
advocates, farmers, etc. - Learn how the price of produce differs
- between farmers markets and supermarkets
- in Dorchester and Roxbury
- Focus on specifics of a well-defined
- geographic/demographic area
- Assess relative quality between locations
5Methods Variable Selection
- Neighborhoods
- North Dorchester, South Dorchester, Roxbury
- Similar socio-economic statistics, outlet
density, momentum - Retail Outlets
- All 10 FM and 7 SM in 8 mile area
- FM implemented for variety of reasons
- All outlets accept SNAP/EBT, WIC all FM accept
FMNP and BBB - Time Periods
- Eight 14-day periods between July 5 and October
24, 2010 - Vendor Research
- Organic certification, time between point of
harvest and sale, pricing strategies

7Methods Variable Selection
- Produce Types
- Carrots unpeeled, with green tops and w/o green
tops - Cucumbers unwrapped, not English
- Onions yellow, large, loose (not bagged)
- Tomatoes (field) about fist size, not hot house/
greenhouse, not heirloom, no vine - Zucchini green summer squash
- White Potatoes loose
- Scallions green onions (not red bulb)
- Lettuce green leaf, not romaine/Bibb/iceberg
variety, not bagged/washed/trimmed - Bell Peppers (green) loose
- Green Beans loose

8Methods Data Collection
- All observations were taken within the same
14-day period - Recorded price/lb. data for the smallest, most
conventional (i.e. non-organic) unit sold - If non-pound unit, recorded unit price and took
RS of unit weight to be converted into price/lb. - Ranked overall visual quality of the produce item
using a scale of 1 to 3 - All data collectors went through training
workshop in order to ensure consistency - Many problem-specific strategies
9Description of Data
- Only 45 of possible observations at FM were
actually realized and included in the final data
set, compared with 88 of possible observations
at SM. - Both location types have fairly equal
representation in the final data set - An unrealized data point most commonly resulted
from the case that a certain produce item was not
available at the time or day of data collection,
but may have also been the consequence of
misreported data, a sold out item, or market
cancellation due to weather, among others. - The variance of mean price per pound at FM
(0.904) was significantly lower (p .026) than
the variance for the same value at SM (0.985),
meaning that overall variation in mean price per
pound was greater at SM. -
- Mean quality at FM (2.74) was significantly
higher (p lt 0.00) than at SM (2.46) by .27, or
about 11. - The standard deviation of quality rating was also
lower at FM (0.47) than at SM (0.62), indicating
that SM reported greater variation in quality.
10Data Analysis
Multivariate Regression Model

TIME7 ?9 PROD1 ?17 PROD9 ?18 QUAL1
?19 QUAL2 E
- How does the mean price per pound (PRICE) change
with variation in location type (LOCATION), while
produce type (PRODUCE), time period (TIME), and
quality rating (QUALITY) are held constant? - Results verified using log transformation to
enhance normality of distribution - Statistical analyses were performed using STATA,
version 9.0 (StataCorp, College Station, TX,
2008).
11Regression Model
Regression Summary of lnPRICE on Successive Fixed
Effects
- A regression of the dependent variable lnPRICE on
LOCATION controlling for PRODUCE, TIME, and
QUALITY yields an estimated coefficient of .029
and a p-value of 0.043. These results suggest
that when produce type, time period, and quality
are held constant, the price per pound is 2.9
greater at farmers markets. The very low
p-value of .043 asserts the statistical
significance of this result.

16Other Discount Opportunities
- Bulk discounts
- i.e. Shaws loose onions were sold for 1.79/lb.
compared with a 2 lb. package of onions for
0.92/lb (about a 50 discount), and Tropical
Foods sold loose potatoes for 0.79/lb. compared
with a 5 lb. bag for 0.34/lb (nearly a 60
discount). - Value card discounts
- i.e. Stop and Shop Card offered zucchini for
0.50/lb. (regular price 1.49) or green beans
for 0.20/lb. (regular price 1.69). - Bounty Bucks
- Up to 10.00 in free produce for SNAP users
17More on Quality
- Organic or IPM Growing Methods
- 2 vendors certified (Langwater and Serving
Ourselves), all others practice mostly organic
growing methods - Freshness
- All produce was grown within 2 hours driving time
of Boston - Likely sold within 24-48 hours of harvest
Examples of Comments on Quality
18How Much Really is 3?
- The Economic Research Service of the USDA
recently announced that an adult on a
2,000-calorie diet could satisfy recommendations
for fruit and vegetable consumption in the 2010
Dietary Guidelines for Americans at an average of
2 to 2.50 per day (Stewart et al., 2008). - Using a mean of 2.25, an increase by 3 would
increase daily cost of consuming the recommended
F V amount by about 7-cents to 2.32. - Over the course of the 16-week/112 day summer
market season used in this study, purchasing the
recommended daily amount of produce would
increase from 252.00 to 259.84- just under
8.00 over 4 months. - This added expense could be more than compensated
for in just one day using Bounty Bucks!
19How can this information be used to educate
consumers about the affordability of neighborhood
farmers markets?
- Focus on the seasonal height of specific produce
types and use time-sensitive publicity to
encourage purchasing when price is lowest. For
example, highlight bell peppers and cucumbers as
Top Pickings or Highest Seeds during the last
two weeks of September (time period 6), and do
the same for scallions and lettuce during the
first two weeks in October (time period 7). - Create a citywide graphic that shows a visual of
how much produce 20 could get a SNAP user at
farmers markets and how that produce translates
into a few days worth of vegetable servings. - Create a side-by-side visual comparison of the
amount of produce a shopper could buy using 10
worth of SNAP at a supermarket, then show that
same amount doubled for farmers markets to
demonstrate the double voucher benefits available
through Boston Bounty Bucks.
