Why Evidence Based Decision Making?

• Limited resources to address needs

• Multiple policy options to address needs

• Rigorous evidence often lacking to prioritize policy options and program elements

Active Labor Market Policies:Getting Unemployed into Jobs

• Improve matching of workers and jobs

• Assist in job search• Improve quality of labor supply

• Business training, vocational training• Provide direct labor incentives

• Job creation schemes such as public works

International Evidence on Effectiveness of ALMPs

• Active Labor Market Policy Evaluations: A Meta Analysis. By David Card, Jochen Kluve, and Andrea Weber (2009)• Review of 97 studies between 1995-2007

• The Effectiveness of European Active Labor Market Policy. By Jochen Kluve (2006) • Review of 73 studies between 2002-2005

Do ALMPs Help Unemployed Find Work?(Card et al. (2009), Kluve (2006))

• Subsidized public sector employment• Relatively Ineffective

• Job search assistance (often least expensive)• Generally favorable, especially in short run• Combined with sanctions (e.g. UK “New Deal”)

promising

• Classroom and on-the-job training• Not especially favorable in short-run• More positive impacts after 2 years

Do ALMPs Help Unemployed Find Work?(Card et al. (2009), Kluve (2006))

• ALMPs targeted at youth• Findings mixed

The Impact Evaluation Challenge

• Impact is difference in outcome with and without program for those beneficiaries who participate in the program

• Problem: beneficiaries have only one existence; they participate in the program or they do not.

Page 10: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

Impact Evaluation Challenge: before – after comparison ok?

before after

$1000

$2000

Skills Training

Program Impact = $1000 extra income?

Income for beneficiary increases from $1000 to $2000 after training

Page 11: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

11

Impact Evaluation Challenge: before – after often incorrect

before after

$1000

$2000

NO Skills Training

NO! Program Impact = $500 $1500

Income for the same person but without training would have increased from $1000 to $1500 because of improving economy

Page 12: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

Impact Evaluation Challenge

•Solution: a proper comparison group

• Comparison outcomes must be identical to treatment group outcomes, if the treatment group did not participate in the program.

Impact Evaluation Approaches

Ex ante:1.Randomized evaluations2.Double-difference (DD) methods

Ex post:3. Propensity score matching (PSM)4. Regression discontinuity (RD) design5. Instrumental variable (IV) methods

Random assignment

before after

$1000

$2000

Skills Training

Program Impact = $500

$1500

Income comparison group is $1500

Income treatment group is $2000

Page 15: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

15

Randomized AssignmentEnsures Proper Comparison Group

• Ensures treatment and comparison at start of program are the same (background and outcomes)

• Any differences that arise after program must be due to the program and not due to selection-bias

• “Gold” standard for evaluations; not always feasible

Page 16: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

Examples Randomized ALMP Evaluations

• Improve matching of workers and jobs• Counseling the unemployed in France

• Improve quality of labor supply• Providing vocationally focused training for

disadvantaged youth in USA (Job Corps)

• Provide direct labor demand / supply incentives• Canadian Self-Sufficiency Project

Challenges to Randomized Designs

•Cost

•Ethical concerns: withholding a potentially beneficial program may be unethical

• Ethical concern must be balanced with:• programs cannot reach all beneficiaries (and randomization may be fairest)

• knowing the program impact may have large potential benefits for society …

Societal Benefits

• Rigorous findings lead to scale-up:

•Various US ALMP programs – funding by US Congress contingent on positive IE findings

• Opportunidades (PROGRESA) – Mexico

• Primary school deworming – Kenya

• Balsakhi remedial education – India

World Bank’s Development Impact Evaluation Initiative (DIME)

• 12 Impact Evaluation Clusters:• Conditional Cash Transfers• Early Childhood Development• Education Service Delivery• HIV/AIDS Treatment and Prevention• Local Development• Malaria Control• Pay-for-Performance in Health• Rural Roads• Rural Electrification• Urban Upgrading• ALMP and Youth Employment

Other Evaluation Approaches

Ex ante:1.Randomized evaluations2.Double-difference (DD) methods

Ex post:3. Propensity score matching (PSM)4. Regression discontinuity (RD) design5. Instrumental variable (IV) methods

Non-Randomized Impact Evaluations “Quasi-experimental methods”

•Comparison group constructed by evaluator

• Challenge: evaluator can never be sure if behaviour of comparison group mimics that of treatment group without program: selection bias

Page 23: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

23

Example: Suppose Only Very Motivated Underemployed Seek Extra Skills Training

• Data on (very motivated) under-employed individuals who participated in skills training.

• Construct comparison group from (less motivated) under-employed who did not participate in skills training.

• DD method: evaluator compares increase in average incomes between two groups

Page 24: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

Double-Difference (DD) Method

Treatment group

Comparison group (non-randomization)

Program impact (positive bias)

Page 25: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

25

Non-experimental design

•May provide unbiased impact answer•Relies on assumptions regarding comparison•Usually impossible to verify assumptions

•Bias always smaller if evaluator has detailed background variables (covariates)

Page 26: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

26

Assessing Validity of Non-Randomized Impact Evaluations

• Verify pre-program characteristics are same between treatment and comparison

• Test ‘impact’ of program on outcome variable that should not be affected by the program

• Note: will always hold in properly designed randomized evaluations

Page 27: What Works? Evaluating the Impact of Active Labor Market Policies May 2010, Budapest, Hungary Joost de Laat (PhD), Economist, Human Development

27

Conclusion

•Everything else equal, experimental designs are preferred. Assess case-by-case.•Most appropriate when:

• New program in pilot phase• Not in pilot phase but receives large

amounts of resources and its impact is questioned

•Non-experimental evaluations often cheaper; interpretation of results requires more scrutiny
