Study Notes
Introduction to Savings and the Poor
- Credit markets do not function smoothly for the poor
- This leads to new financial products to help the poor, such as microcredit
- This lecture examines poor people's savings and challenges to overcoming poverty through saving.
Motive for Savings: Intertemporal Consumption Smoothing
- Individuals live two periods; work in one and retire in the second.
- Income is represented as (1,0) over two periods
- Utility function (u(c)) shows diminishing marginal returns (concave)
- A specific example of a concave utility function is u(c)=In(c)
- β is the discount factor, reflecting how much an individual discounts future utility
- If β = 1, the individual is fully patient and waiting a period does not affect utility
- If β < 1, the individual prefers consuming today to consuming tomorrow
- For simplicity, the interest rate (R) is assumed to be 1
- The marginal return from consumption decreases as the consumption level increases.
- Consuming x in period 1 provides In(x) utility, and in period 2 provides β*In(x) from the perspective of period 1
- The marginal utility from consumption (u'(c)) shows diminishing returns (decreasing with increasing consumption)
- The optimal consumption allocation equalizes marginal utility from consumption across periods, relative to the discount factor.
- Using u(c) = In(c) implies c1 / c2= β
- Individual should consume similar levels across periods, only an adjustment for β
- Individuals who are less patient (lower β value) want to consume less in the future and more today.
- The desire to smooth consumption over time is a crucial motivation for saving.
Motive for Savings: Self-Insurance
- Savings help with "uninsurable" risks (e.g., income shocks) not covered by typical insurance
- Concave utility and lack of complete market insurance increase precautionary savings
- This need for precautionary savings is especially important for the poor, who often face greater daily risks.
- Savings also depend on how much uncertainty there is about future income
- More savings than expected for those without uncertainty
- This is called "precautionary saving"
Behavioral Biases
- Recent brain evolution focuses on the prefrontal cortex (controls deliberative processes)
- Damage to prefrontal cortex can affect decision-making where deliberation is required
- This evolution did not replace earlier brain functions, but expanded it
- This leads to two types of individuals
- Time-consistent
- Time-inconsistent
- Individuals exhibit time inconsistency in choices: e.g., preference between an immediate fruit versus a chocolate bar next week are significantly different in the actual choice vs the theory of time-consistency. This is not true for very distant future choices (longer than a year).
- Examples such as gym memberships and the desire to go to the gym, preference between low-brow/high-brow videos, and the preference for fruit vs. chocolate next week versus today.
Commitment - Tying Odysseus to the Mast
- People are willing to commit to actions, often by paying a cost (e.g., gym memberships).
- Commitment mechanisms prevent future choices, to ensure today's commitment.
- Committing to long-term savings can be beneficial against time inconsistency.
Evidence from Philippines - SEED Account
- Study in the Philippines (with Green Bank of Caraga)
- Survey of 1777 existing/former clients to identify behaviors
- Half randomly selected to have a new "SEED" account
- SEED account is a pure commitment savings product with restricted access, allowing only small daily deposits
- No compensation for the restriction (same interest rate as a regular savings account)
- Other clients in the control group received no further encouragement/marketing or were only encouraged to save more.
- SEED account clients used it for withdrawals within specific time frames (e.g., school, Christmas) or amounts, such as a house roof.
SEED Design - How To Identify Who Has Commitment Problem?
- Testing time-consistent preferences: determining if people have difficulty with commitment/self-control issues
- Using hypothetical time discounting questions
- This helps figure out if the individuals who have time-inconsistent preferences do save more if they are given a commitment mechanism
SEED Design - Results
- Time-inconsistent individuals (impatient now, but patient for the future) take up the SEED product more frequently
- Females with hyperbolic preferences (about money) also take up the SEED product, by 15.8 % more than men
- Hyperbolic preferences is robust when controlling for income, assets, household composition, and other factors
- Results are smaller and less significant for men
- Research to check for new vs existing saving through checking for changes in balances on non-commitment accounts. This is consistent with the result that commitment works in new savings, not existing ones
SEED Conclusions
- Savings require delaying immediate rewards for greater future rewards
- Individuals with hyperbolic preferences ("impatient now, patient tomorrow", for instance) have self-control problems.
- Difficult to save.
- "Preference for commitment" makes commitment mechanism beneficial - makes those who save harder.
- Hypothetical questions help to test/identify individual time preferences and investigate if offering a commitment device improves savings amongst those with these issues, such as difficulties with commitment/self-control issues.
Additional Considerations on Welfare Implications
- Ambiguous welfare implications; improved savings does not ensure overall wellbeing
- Loss of liquidity can harm individuals
- Further research is recommended

Description
This quiz explores the relationship between savings and poverty, focusing on how credit markets impact the poor. It also discusses innovative financial products, like microcredit, aimed at assisting low-income individuals in saving. Understanding the motive for savings through intertemporal consumption smoothing is also a key component of this section.
