Learning Incentive Schemes for the Working Poor Catherine Eckel University of Texas, Dallas Cathleen Johnson CIrANO Claude Montmarquette University of Montreal and CIRANO Evidence-Based Public Policy: New Tools from Experimental Economic 2005
Why Experimental Economics? • The effectiveness of a policy can be enhanced substantially if it is tailored to the preferences of the target population
New Addition to Economist’s Toolkit • Has the potential to outperform the two traditional empirical methodologies: • Outcome based measures • Survey questions
Advantages of Laboratory Experiments • Decisions involve real money, costly decisions • Real, not hypothetical decisions • Control for situational variation by placing subjects in identical settings
Securing External Validity • Relevant aspects of the decision-making context are incorporated • Substantial stakes
Key Research Question Given the right incentive, will the working poor save to invest in human capital?
The Laboratory Experiment The laboratory experiment focused on three major questions: • Will the working poor invest in various assets? • Are these subjects willing to delay consumption for substantial returns? And • How do these subjects view risky choices?
Subjects • Community groups whose membership primarily consisted of working poor helped with recruitment
Subjects • 256 subjects • 2/3 women • Seventy-two percent of subjects partcipate in the labor market
Subjects • Far from being uneducated • 78% high school diploma • And 26% university degree • 72 percent had a family income of less than 120 percent of Statistics Canada Low Income Cutoff (120-Lico) • Total household income $20-25,000 on average
Experimental Instruments Two surveys: • Information questions (43) • Socioeconomic • Behavioural • Attitudinal • Compensated questions (64)
Protocol • $12 Show-up fee, child care and bus fare • Practice Choice Questions • Bingo balls used for random draw process • Dice were used for gambles • Distributed 2 surveys • As individuals finished they left the room and were paid privately for one choice question
Compensated Questions - 64 • Investment Preferences • Cash v. Investment choices • Time Preferences • Cash v. Cash later • Risk Preferences • Cash v. Risky cash
Investment Preferences • Cash v. Investment Choice • Cash alternative made the choice of investment costly to the subject • pinpoint optimal match rates for the learn$avedemonstration and • Gather the information necessary for determining preference ordering between different forms of investment
% of participants choosing family member’s education over $100 one week from today Labour Force Participants Non-Labour Force Participants
% participants that chose retirement savings over cash one week from the day of the experiment
Time Preference • We elicit a series of time preferences by asking subjects when they prefer to take their compensation • Choices vary in terms of • initial payoffs and • alternative payoffs with respect to • day lapsed and • discount rates
Time Preference • Using these responses • Measure overall degree of patience • Shape of the subject’s discount function
Creating Indexes • It is well known that impatience and attitude toward risk influence both the decisions to invest in human capital and to save for future consumption • Our experiment uses choice questions with monetary payoffs to construct measures of these characteristics
Determinants of the Impatience Index for Each Individual • Younger subjects and men favour the earliest choices • We can conclude that the women were more patient than the men in our sample, choosing on average to delay payment for three more decisions than men • The number of children does not seem to affect patience 256
Determinants of the Proportion of Subjects Choosing Early Payoff • Delaying alternative payoff reduces the incentive to pick the latest alternative • Increasing the rate of return induces subjects to delay reward • Absolute difference encourages the subjects to delay their reward
Risk Preference • Elicit the participant’s attitude towards risk • Obtain a behavioural measure of risk aversion with 14 pairs of lottery questions • Risk aversion for monetary payoffs
Risk Aversion Index • LESS RISKY CHOICES is a simple count of the number of times the subject has chosen the safest payoff (0-14)
Descriptive Statistics • 16.4 % of sample always chose the earliest payoff (5.1% always saved) • 16.4 % of sample always chose the safest lottery payoff (2.3% riskiest) • 15.2% chose cash over every investment option (5.5% investment over cash)
Analysis Education Preference Overall intensity of preference for education (No, some, strong, very strong) Is a function of • Time Preference (experimentally measured) • Risk Preference (experimentally measured) • Other attitudes and perceptions (survey) • Socioeconomic characteristics (survey)
Determinants of Choosing Educational Expenses over Cash • Impatient subjects exhibit a higher probability to choose cash over education • More risk averse subjects show a lower probability of investing in human capital • Younger subjects more likely to invest • Those with some post secondary education were also more likely to invest
Determinants of Choosing Cash over Family Member’s Education • Children increase probability of investment • Students have higher probability of choosing cash • Impatient subjects have higher probability of taking cash • Risk aversion measure plays no role
What Have We Learned So Far? • In general, the working poor in our sample are risk averse and impatient • Nevertheless, many can be induced to invest in their own education • 44 percent accepted analogous learn$ave offer • Overall, own educational expenses was preferred to family member’s education and retirement savings • Some couldn’t be induced to invest in any asset even when return approached 500%
What Have We Learned So Far? • Savings programs may benefit from higher take-up rates if they • Offer high returns • Stress absolute returns • Allow short term savings horizons
