Hungary, 18.05.2011
case 1 – Evaluation of @lternative II project
• Objective of the project: preventing unemployment among young people.
• The territorial scope: 59 poviats of Poland (NUTS 4) with unemployment
rate above 20% and high unemployment among young people.
• Eligibility:
• young unemployed (27 or younger),
• registered at the labour office.
• Total number of beneficiaries: 5 657.
• Budget: € 4 090 702.
• Type of services: pre-training assistance (recruitment, needs assessment,
guidance); vocational training services linked with ECDL, both at basic and
advanced level, as well as related areas; practical training (temporary
employment/ on the job training organised under the agreements signed with
employers; training allowances; vocational guidance and post training
assistance; job-broking.
• Period of implementation: 2005-2006.

The selection bias problem in
control/comparison group approach
To estimate the impact of the intervention
we cannot simply compare beneficiaries
(treated) with those who did not
participate in the project (non-treated)
 This is because of factors affecting both
participation and outcomes.
 If we don't control for those factors, we
can overestimate or underestimate the
impacts(picking the winners/ picking the
losers).

Data used in the evaluation
PULS System, which:
• is used for services for the unemployed
• is present in approximately 90% of Poviat Labour
Offices in Poland (2006)
• provides a wide range of data on each
unemployed person (socio-demographics,
employment characteristics, previous qualification
improvement, skills etc. ),
• includes a detailed history of unemployment and
other activities on each person (registration in
the office, deregistration, trainings, use of the
benefits, etc.).
Data collection
• We collected data from 55 of the 59 Poviat Labour
Offices involved in the project.
• In total we managed to identify 5 065 participants
of the @lternative II project (90% of all
beneficiaries).
• Moreover we collected data on 126 633 persons
(non-treated), which meet the formal conditions for
eligibility for the project (registration in the labour
office, age condition).

Bearing in mind the assumptions…
Conditional Independence Assumption
Population A
Counterfactual
Treatment
action
Population B
Counterfactual
Treatment
action
• We assume that if we can control for observable differences in characteristics
between the beneficiares and non-treated population, the outcome (observable
change) that would result in the absence of treatment (counterfactual action) is
the same in both populations.
• Ergo, we assume that unobservables do not affect the outcomes!

(Counter)example 2 –
Entrepreneurship promotion project
• Objective of the project: encouraging business
activities among unemployed people.
• Beneficiaries: unemployed people (with priority
to young job-seekers).
• Type of services: initial business training;
guidance on conducting economic activities;
training allowance; relevant specialised training;
coaching after setting up a business.
• Time of implementation: 2004-2005.
• Evaluation framework: the same approach as
in the @lternativa II exaple (the same
methodology, source of data, analysis...).

Lessons learned/points for the discussion

What data we were lacking in both examples?
◦ Missing covariates? (Are our assumptions plausible?)
◦ Missing outcome variables?
What do we know and what we don't know after
completing the evaluation (towards theory based impact
evaluation)?
 How we could modify the plan of the evaluaton to get
more insight on impacts (targeting issue)?
 What is the avaibility of systems such as PULS in other
EU countries (looking for possibilities of implementing
IE)?
 What is the utility of data collected in public statistics?
Do we need new data systems for IE or maybe we need
to modify existing ones? (towards more systematic
discussion on IE planning).

Thank you!!!
