What Would You Do With $500? Spending Responses to Gains, Losses, News and Loans Andreas Fuster Greg Kaplan Basit Zafar Reserve Bank of New Zealand December 2017 Another Paper Estimating MPCs ? Approaches to estimating MPCs: 1. Revealed
Another Paper Estimating MPCs ?
- Approaches to estimating MPCs:
- 1. Revealed reference: natural experiments, transitory income
- 2. Reported preferences: hypothetical surveys
- Lessons from revealed preference literature:
- Average quarterly MPC: 15%-30%
- Heterogenous, bi-modal, correlated with liquid wealth
- Limited power for developing and distinguishing theories
- Natural experiments: mostly one-time unanticipated windfalls
- Correlating with observables: limited to liquid wealth
1 Fuster, Kaplan and Zafar (2017)
This Paper
- Use hypothetical survey responses to test and refine existing models
- f consumption behavior
- Within-person variation from alternative treatments:
- GAIN: size effect
- LOSS: sign asymmetry
- NEWS about gains and losses
- LOAN
- Better hypothetical survey questions than existing literature
- Compare with theoretical predictions from simple models
- Implement treatments in calibrated life-cycle models
2 Fuster, Kaplan and Zafar (2017)
Main Findings
- Responses to GAIN treatment largely consistent with existing literature
- Insights from additional treatmets:
- 1. (i) Sign asymmetry: LOSS > GAIN;
(ii) No response to NEWS-GAIN ⇒ importance of low levels of liquid wealth
- 2. Response to NEWS-LOSS ⇒ not just myopia
- 3. No response to LOAN ⇒ not short-term credit constraints
- 4. Size effects ⇒ non-convexities, durables, salience may play a role

Baseline Survey Instrument
GAIN: Quarterly MPC out of one-time unexpected receipt of $Y
- Asks respondents how spending behavior would change over
subsequent three months in response to unexpected increase in resources.
- Three amounts: $500, $2500, $5000
- Elicit spending response in two stages:
- 1. Ask whether spending / debt payments / savings would change in
response to windfall
- 2. Ask about magnitude of change

Reported Expenditures in the Literature
- Shapiro-Slemrod, Parker-Souleles
Thinking about your (family’s) financial situation this year, will XX lead you mostly to increase spending, mostly to increase saving, or mostly to pay off debt?
- Japelli-Pistaferri (Italy)
Imagine you unexpectedly receive a reimbursement equal to the amount your household earns in a month. How much of it would you save and how much would you spend? Please give the percentage you would save and the percentage you would spend.
- Graziani-van der Klaauw-Zafar
What are you doing or planning to do with the extra income? Asked to report the share planning to spend / save / pay down debt.
10 Fuster, Kaplan and Zafar (2017)
Reported Expenditures in the Literature
- Christelis-Georgarakos-Jappelli-Pistaferri-van Rooij (Netherlands)
Imagine you unexpectedly receive a one-time bonus from the government equal to the amount of net income your household earns in (one-month / three months). In the next 12 months, how would you use this unexpected income transfer? Distribute 100 points over these four possible uses:
- 1. Save for future expenses [0 …100]
- 2. Repay debt [0 …100]
- 3. Purchase within 12 months durable goods (cars, home improvement, furniture, jewelry, other
durable good) that you otherwise would not have purchased or that you would have purchased later [0 …100]
- 4. Purchase within 12 months non-durable goods and services that do not last in time (food,
clothes, travel, vacation, etc.) [0 …100]
- Boon-Le Roux-Reinold-Surico (UK)
If your household received an unexpected windfall of [amount] tomorrow, what do you think you would do with this extra money?
- I would spend all [100%] or more this year
- I would spend between [75%] and [100%] more this year
- I would spend between [50%] and [75%] more this year
- I would spend between [25%] and [50%] more this year
- I would spend between [1] and [25%] more this year
- I would not change spending and save the windfall
- I would not change spending and use the windfall to pay off some of my debt
11 Fuster, Kaplan and Zafar (2017)
Advantages of Our Questions
- Explicitly state size of windfall, allowing it to be varied
- Two-stage approach:
- Allows more precise estimates of zero MPCs
- Does not prime respondents toward a non-zero response
- Explicit about time horizon over which spending response is measured
- Does not impose that MPC is between 0 and 1
- Richer information from alternative treatments
12 Fuster, Kaplan and Zafar (2017)
Treatments
- GAIN: Quarterly MPC out of one-time unexpected gain of $Y
- LOSS: Quarterly MPC out of one-time unexpected loss of $Y
- NEWS-GAIN: Quarterly MPC out of unexpected news about a gain of
$Y to be received Z quarters from from now
- NEWS-LOSS: Quarterly MPC out of unexpected news about a loss of
$Y to be received Z quarters from from now
- LOAN: Quarterly MPC out of unexpected interest-free loan of $Y to be
repaid 1 year from from now
- Respondents exposed to two treatments in each module
- Order of treatments within a module was randomized

News: Conditional on Responding to Loss
- Among subset who do respond to a loss today, three-quarters would
also respond to a future loss, with similar distribution
- Over half these households respond to news about loss in 2 years
- Evidence against extreme myopia.

about future gains, even those with large responses to actual gains
- 5. Response to news about losses: People do respond to news about
future losses, even those with low liquid assets
- 6. No response to loans: Even for people who respond to gains

Framework and Definitions
- Budget constraint in quarter t
cit + sit = xit xi,t+1 = yi,t+1 + Rsit,
- GAIN and LOSS: constraint unexpectedly becomes:
cit + sit = xit + ∆ xi,t+1 = yi,t+1 + Rsit,
- NEWS-GAIN and NEWS-LOSS: constraint unexpectedly becomes:
cit + sit = xit xi,t+1 = yi,t+1 + Rsit + ∆,
- LOAN: constraint at t becomes cit + sit = xit + ∆
constraint at t + 4 becomes xi,t+4 = yi,t+4 + R (si,t+3) sit+3 − ∆

Rule-of-Thumb Consumers
- Consume all disposable income every period
MPCG = MPCL = MPCLN = 1 MPCNG = MPCNL = 0
- No size effect
- No sign asymmetry
- Not consistent with NEWS-LOSS: people are forward looking
31 Fuster, Kaplan and Zafar (2017)
PIH Consumers
- Quadratic utility, fixed interest rate R = β−1, No-Ponzi schemes
MPCL = MPCG = r 1 + r ≈ 0 MPCNL = MPCNG = r (1 + r)2 ≈ 0 MPCLN = r 1 + r − r (1 + r)5 ≈ 0 where approximations hold for small r
- MPCG = MPCL: small for everyone, no sign asymmetry
- Similar response to news as to gains / losses
- MPCG ≈ MPCNG: consistent with NEWS-GAIN
- MPCL ≈ MPCNL: not consistent NEWS-LOSS
32 Fuster, Kaplan and Zafar (2017)
Spender-Saver Model
- Fraction α rule-of-thumb (spenders), fraction 1 − α PIH (savers):
MPCG = MPCL = MPCLN = α MPCNG = MPCNL = 0
- Simple, popular modeling choice:
- Heterogenous MPCG
- Smaller response to news than gains: MPCNG < MPCG
- MPCL correlated with liquid wealth as in data
- No size effect
- No sign asymmetry
- Not consistent with NEWS-LOSS

Predictions from Infinite-Horizon Model
V (x) = max
c,s≥0 u (c) + βE [V (x′, y ′)]
subject to c + s = x x′ = Rs + y ′
- Strict concavity of consumption function c(x): MPCL > MPCG
- For large x consumption function is approximately linear:
c(x) → [ R (βR)
1 γ − 1
] x
- In practice, approximation holds well except for low wealth households
near borrowing constraint
34 Fuster, Kaplan and Zafar (2017)
High and Medium Wealth Households
- No sign asymmetry: MPCG = MPCL
- No size effect: MPCG = MPCL ≈ r for βR ≈ 1
- Similar responses to news vs gains / losses
MPCNG = 1 RMPCG MPCNL = 1 RMPCL (differ only because of discounting)
- For households sufficiently far from constraint MPCLN ≈ 0 (order r 2)
35 Fuster, Kaplan and Zafar (2017)
Very Low Wealth Households
- Sign asymmetry, size effect:
- Large response to losses of all sizes: MPCL = 1 for all ∆
- Responses to gain:MPCG ≤ 1 depending on size of ∆
- NEWS-GAIN and NEWS-LOSS
- MPCNG = 0: learn about HtM from MPCG − MPCNG
- MPCNL: depend on reason for being low wealth
- LOAN
- Depends on how long a household expects to be constrained for
- Very impatient of present biased households: expect to take up
loan, like the rule-of-thumb

Adapted from Kaplan and Violante (2010,14)
- Quarterly lifecycle model: 38 yrs working , 20 yrs retirement
- Utility over non-durables and housing services:
u(c, s) = ( cφs1−φ)1−γ 1 − γ with γ = 2, φ = 0.85
- Idiosyncratic income risk: age profile + AR(1), ρ = 0.97
- Two assets:
- Liquid asset: r l = 0%
- Illiquid asset: r a = 5%, housing services = 3%
- Fixed transaction cost = $2, 000
- Discount factor β so ratio of av wealth to av. ann. earnings = 3.5
- One asset models: φ = 1, r l ∈ {0%, 5%}

Concluding Thoughts
- Moving beyond MPC’s for unexpected gains: useful for guiding theory
- In the absence of natural experiments, suitably designed hypothetical
surveys can offer new insights into consumption behavior
- Key findings:
- 1. (i) Size asymmetry: LOSS > GAIN;
(ii) No response to NEWS-GAIN ⇒ importance of low levels of liquid wealth
- 2. Response to NEWS-LOSS ⇒ not just myopia
- 3. No response to LOAN: ⇒ not short-term credit constraints
- 4. Size effects: ⇒ non-convexities, durables or salience
- To do: explore behavioral phenomena: present-bias, inattention,
mental accounting etc
