3. Street-Vendors
Represent 2% of urban population
Source of self employment for the urban poor
Source of affordable food to large part of the
urban population
In Kolkata estimates say there are 150.000
street-food vendors (NCEUS, 2007)
Project Motivation
4. However, street vendors suffer a welfare loss
because they work in the informal sector:
They are subject to arbitrary evictions
They are potential victims of abuses from
authorities
They cannot demand any right
Formalization may help vendors!
5. The national government is working to
formalize street-vendors expecting that…
“Vendors will suddenly change their
behaviours”
The main hypothesis of the study is that
street-food vendors lack the necessary
awareness and capability to make alone such
a change in behaviour
Project offers an innovative training to help
vendors in this process: specifically, to
improve their awareness and capability
6. Awareness about:
National hawkers act for protection and
livelihood
Maintaining minimum Hygienic standards
Health hazards
Capability about:
How to deal with hygienic standards and health
hazards
How to improve their business
7. Project offers a training designed for street-food
vendors in urban India
Three workshops & follow-up visits at each kiosk
Study took place in April,15-June,16
How can we test the impact of the training?
How can we explain the change in behavior?
Impact Evaluation: Randomized Control Trial
2. Methodology
8. The workshop offered to about 600 vendors
Vendors have been randomly selected
We selected vendors from different areas of the city
to have a representative sample of all the areas of
Kolkata
We use a statistical software (STATA) to implement
the randomization and the statistical analysis
9. Vendors are randomly assigned to different groups in
order to test the most effective way to improve
vendors’ performances!
Vendors are randomly assigned to 4 groups:
Group 1: pilot group for field testing
Group 2: 3 –trainings within a period of 75 days
Group 3: 3 –trainings within a period of 75 days along
with promotional materials
Group 4: control group ( nothing done except
monitoring)
10. The first baseline survey has been
collected in the period March-May 2015
The following analysis is based on 924
collected surveys
86% of vendors interviewed are owners of
the kiosk

Do you expect this training can improve your earnings?
• 93% of vendors are interested in participating in a
training
33. Water & other tools
95% of vendors providing water, use water
from a common container
68% has a dustbin
Only 1% uses an apron
29% have “dirty” towels/cloths
34. Hygiene of the kiosk & cooking area
38% had dirt or food debris on the floor
26% had dust in the cooking area
35. Food
35% Have raw food not covered
25% Have cooked food not covered
36. Disposable Tools
32% of vendors use disposable plates
9% of vendors use disposable forks/spoons
32% of vendors use disposable glasses
37. Using STATA, we created an index which
measures vendors’ hygienic standards based
on the previous indicators
This index aggregates all the observed
behaviour into a unique number
The index takes value 0 for the lowest level
of hygiene and value 1 for the highest level
Note: “1” can be interpreted as “behaving
according to the National Act”
38. • The average value is 0.57
Less Hygiene More Hygiene
39. • No big differences across areas!
Less Hygiene More Hygiene
