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

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

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)

slide-14
SLIDE 14

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

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

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 − ∆

  • MPC for treatment T ∈ {G, L, NG, NL, LN}:

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)

slide-43
SLIDE 43

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)

SLIDE 44

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)

slide-47
SLIDE 47

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)

slide-48
SLIDE 48

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
