Study Notes
Introduction
- Credit markets do not function smoothly for the poor
- New products like micro-credit help address this issue
- This lecture focuses on poor savings and the challenges of escaping the poverty trap
Motive for Savings: Intertemporal Consumption Smoothing
- Individuals save to smooth consumption over their lifetime
- Income is earned in one period, and not in another
- Utility is concave, meaning the marginal utility of consumption declines as consumption increases
- If an individual is fully patient (β = 1), they treat current and future consumption equally
- If an individual is less patient (β < 1), they prefer consuming today rather than tomorrow
- Aim is to smooth out consumption to maximize overall utility
Motive for Savings: Self-Insurance
- People need to insure against unexpected income shocks
- Concave utility functions are standard
- Insufficient insurance products mean precautionary savings are needed
Motive for Savings: Self-Insurance
- Poverty leads to greater risks in daily life, so greater needs for insurance
- Individuals with limited access to insurance markets save to handle risks
- The amount saved relies on the individual's patience
Behavioral Biases
- The prefrontal cortex, although recent in evolutionary terms, controls our deliberative processes.
- This region interacts with older brain regions to regulate emotions and survival.
- Individuals may exhibit time inconsistency, favoring immediate gratification over future needs.
- Individuals with time-inconsistent preferences (impatient now, but patient in the future) have trouble saving.
Commitment - Tying Odysseus to the Mast
- People pay for ways to commit to certain goals
- People use gym memberships to commit to exercise. This is more expensive than pay-per-visit gyms.
- There may be reasons why poor individuals struggle to make decisions
Evidence from Philippines
- A study partners with a Filipino rural bank.
- A survey on time inconsistency preferences was conducted on 1,777 existing or former clients
- A new savings account (SEED) was offered to some clients
- The account restricted access but didn't compensate for this.
- The interest rate remains unchanged in the SEED Account.
- Other clients have different types of savings accounts offered and tracked
- The results are then tracked monthly and bi-monthly.
SEED Design - Withdrawal
- Individuals set time-based, and money-based goals from their SEED accounts.
- Customers may choose a date
- Or a particular amount of funds.
- Decisions are non-changeable once made.
SEED Design - Deposits
- Participants may choose a locked box.
- The box allows easy deposit without going to the bank
- Limits money access through a locked box
- An alternate form of deposits is provided via automatic transfer from an existing account.
SEED Design - How To Identify Who Has Commitment Problem?
- Researchers evaluated how time inconsistency impacted saving behavior
- By use of hypothetical scenarios.
SEED Design - Results
- Time inconsistent people are more likely to sign up for the SEED savings product
- The SEED savings effect is mostly seen in women
- The results are largely robust
SEED Design - Results
- Commitment approach has positive savings effect when compared to standard accounts and marketing efforts
- Results are also influenced by outlying behavior of the individuals
SEED Design - Results
- Researchers examined binary outcome variables to counter the effect of outlier bias.
- Savings increase is substantial in the test group.
- Magnitude of the increase was normalized by initial savings
- Commitment influences the individuals and their savings
SEED Design - Results
- The treatments had a lasting effect on commitment to savings.
- Results are positive and significant.
- Marketing efforts didn't influence results.
SEED Design - Results
- The difference between commitment and marketing group treatment isn't significant.
- There is not much difference in conclusions whether compared with OLS.
- Results are largely driven by outlying behaviour.
SEED Design - Results
- Researchers measured total balances six months and 12 months later.
- This examined whether the overall positive savings response was a short-term or lasting result
- Using binary indicators measure the probability of savings behaviour.
SEED Design - Results
-
Improvements in savings amount stem from new savings accumulation and not from a shifting of assets.
-
Results examined whether savings behaviour from the commitment account influenced savings in other regular accounts.
SEED Design - Results
- Results demonstrated the commitment approach positively impacted savings behaviour
SEED Design - Conclusion
- Savings need patience, forgoing immediate gratification
- Individuals exhibit time inconsistency due to this conflict.
- People are more prone to save when faced with commitments.
- Individual preferences can be difficult to measure and recover.
SEED Design - Conclusion
- Positive savings increase are not always welfare-enhancing.
- Loss of funds liquidity may cause individual harm.
