What explains the long thick tail?
Idiosyncratic earnings risk/skewness and precautionary saving response
Savings increasing with wealth (Non-homothetic bequests)
Heterogeneity in discount rates
Entrepreneurship
These explanations, in isolation, have trouble fitting the data
If they do, it is at the cost of counterfactual assumptions (De Nardiand Fella, 2016)

Stochastic wealth returns
Benhabib et al. (2016)
heterogeneous persistent wealth returns (along with some of thefeatures above) can reproduce the long thick tail of the wealthdistribution (and the extent of intergenerational correlation)
Gabaix et al. (2015)
persistent heterogeneity in returns and correlation of returns withwealth (scale and type dependence) can explain the speed of changesin tail inequality
Merit of this literature: shift in focus from heterogeneity in returns tohuman wealth to heterogeneity in returns to financial wealth

Open questions
Not clear if features emphasized by this recent literature are realisticand whether they are quantitatively important
In particular:
Q1: How much heterogeneity in wealth returns?Q2: How much persistence?Q3: Are returns to wealth correlated with wealth itself?Q4: Is there intergenerational correlation in returns?Q5: Is there assortative mating on returns?
Addressing these questions have proved diffi cult
No administrative information on wealth and capital income for arepresentative sample of individuals or asset classes in the USPopulation surveys (SCF) lack a consistent longitudinal component andhave low response rates at the top
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Our contribution and findings
Use population data on wealth and capital income (by broad assetclasses) for Norway over two decades
Tax records: Cover all tax-payers, including the very wealthy
We can construct returns to wealth for each individual tax-payer
Findings:
massive returns heterogeneitystrong correlation with wealthpersistence
within person (strong), across generations (weak), and intramaritally(weak)

The Norwegian data
Population tax record data from 1993 to 2013
Besides income tax, Norwegians pay also a wealth tax, so tax recordsinclude:
Information on income earned (from labor and capital)
Capital income distinguished by “broad” source Details
Detailed information on asset holdings
Also distinguished by “broad” source Details
For most sources, tax value=market valueFor unlisted stocks, etc., tax value≤market value Details
Our definition of wealth excludes housing (for the time being),(rank)-correlation between two measures high.
Third-party reports
Limited scope for tax evasion
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Wealth Returns: Simplest Measurement
Tax returns include capital income:
yit = interest income + dividends + realized capital gains/losses
They also include the stock of wealth at the beginning of year t (“endof year t − 1”): wit
If no accumulation/decumulation of wealth during the year ("passive"portfolio), the average return would simply be:
rit =yitwit
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Wealth returns measurement: Limitations and Adjustments
1. We only observe snapshots of total financial wealth (beginning/end ofeach period)
We use multiple observation points, and redefine our baseline measureas: Example
rit =yit
(wit + wit+1) /2
2. Value of private equity may be understated
We show results for all individuals and for non-private equity owners
3. Capital gains/losses only observed when shares are sold
Our fixed effect strategy will partly remedy thisWe impute unrealized capital gains/losses
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Future Drafts
Shareholder Registry (2004-16)
Can compute unrealized capital gains on a security-by-security level (asin Bach et al., 2016)
Private businesses’balance sheet data
Can improve return measure using information on retained earnings andshares owned through companies (as in Alstadsæter et al., 2016)
Housing Transaction Registry (2000-16)
Can use hedonic regressions to impute housing capital gains (as inMogstad et al., 2017)

Q1: How much heterogeneity should we expect?
In standard Merton-Samuelson model individuals have access to thesame investments opportunities.
Differences in preferences for risk determine the share of risky assetsin portfolio:
πit =rmt − r ft
γiσ2
The return on wealth is
rit = r ft + πit
(rmt − r ft
)Conditioning on the share of risky assets in portfolio, returns shouldbe similar across investors

Q2: Are returns correlated with wealth levels?
"It is perfectly possible that wealthier people obtain higher averagereturns than less wealthy people.... It is easy to see that such amechanism can automatically lead to a radical divergence in thedistribution of capital" (Piketty, 2014).
Wealthy investors may be more risk tolerant
Wealthy investors can buy the services of “financial experts”(economies of scale in wealth management) or be moreexpert/sophisticated themselves
Wealthy investors may have access to different investmentopportunities than retail investors
Some (more lucrative?) mutual funds have an entry requirementReturn on safe assets have a premium for those depositing above athreshold Safe Assets

Q3: Is returns heterogeneity persistent?
Certain individuals may reap persistently higher/lower returns thanthe average
Preferences
High risk tolerance leading certain individuals to invest inhigh-risk/high-return financial instruments (and preferences for risk arevery stable over time).
Talent
Better at “stock-picking” or at timing the marketBetter financial educationBusiness income/private equity: entrepreneurial ability

Modeling returns heterogeneity
We consider a simple panel data regression model
rit = X ′itβ+ uit
Observables:Lagged wealth =⇒ size effectsLagged share in risky assets, private equity, direct stocks =⇒ riskexposureTime dummies and interactions with shares =⇒ common movementsin returnsAge dummies =⇒ life cycle effects
Unobservables:
uit = fi + εit
How much returns heterogeneity is explained by observables, fixedeffects, and remaining unobservables?

Q4 and Q5: Assortative mating in (returns to) wealth andintergenerational correlation in returns
Benhabib, Bisin and Luo (2016) assume that returns are stochastic,constant within a generation, and persistent across generations
We find a role for intergenerational effects both of returns and thepersistent component of returns. To intergenerational
Our data can also be used to study assortative mating by individualwealth and returns to wealth To assortative mating
we find assortative mating by wealthwe also find some (weaker) assortative mating on returns to wealth(conditional on assortative mating on wealth)both the high and low return spouse matters for the household returns
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Implications of returns heterogeneity
Implications of the evidence presented so far:
Can it explain the extent of wealth inequality and concentration?
What does it say about whether capital income taxation is preferrableto wealth taxation? (Guvenen et al., 2016)
Does it have an impact on measurement of wealth inequality andconcentration based on the capitalization approach? (Saez andZucman, 2016)
Our previous paper (Fagereng et al., 2016) focuses on the latter.Summary
Another paper (in progress) focuses on the first question.

Conclusions
Not much is known about the distribution of returns to financialwealth across individuals and households
This paper provides evidence using population tax records fromNorway
Returns exhibit massive heterogeneity, are correlated with the level ofwealth, and are persistent over time for the same individual andacross generations
Various implications for the debate on the causes and consequences ofwealth inequality

Q4: Are returns to wealth correlated intergenerationally?
Benhabib, Bisin and Luo (2016) assume that returns are stochastic,constant within a generation, and persistent across generations
Persistence may be due to sharing a private business, orintergenerational transmission of preferences for risk or talent forinvestmentHowever, BBL find weak evidence for persistence
Our data can be used to study mobility (or intergenerationalcorrelation) in wealth-related variables

Q5: Is there assortative mating on returns to wealth?
In the literature there is evidence of assortative mating by education,income, and parents’wealth (Eika et al., 2014; Lam, 1988; Charles etal., 2013)
Our data can be used to study assortative mating by individual wealthand returns to wealth
In the data:
we observe couples before they get married (or have children)we find assortative mating by wealthwe also find some (weaker) assortative mating on returns to wealth(conditional on assortative mating on wealth)

Assortative mating on wealth and returns to wealth
Why may people want to sort on returns to wealth?
Similarity of traits - preferences for risk, etc.To preserve whatever wealth they have
Whether this matters depends on who manages the householdresources
If rposti = max{rprew , rpreh
}, then assortative mating on returns
shouldn’t matter
We consider a simple regression:
rposti = β0 + β1max {rprew , rpreh }+ β2min {rprew , rpreh }+ ei

Valuation of unlisted stocks
In addition to balance sheet information, unlisted companies have tosubmit a statement to the tax authorities detailing the “Estimatedtotal value of the company” (“Beregnet samlet verdi bakaksjene iselskapet”)
This may differ from the company’s book value of equity (althoughρ = 0.88) Graph
The estimate does not include net present value calculations orgoodwill
Companies with >5M NOK (approx. $500k) are subject to an auditobligation in the following financial year

Explaining the decline in returns at the very top
At the top 1%, more than 60% of wealth is held in private equity(entrepreneurship)
Three possibilities:
tax evasion (Zucman, 2016)"pivate equity premium puzzle" (Moskowitz and Vissing-Jorgensen,2002)direct control over dividend policy (Alstadsæter, Kopczuk and Telle,2014)

Measurement of wealth inequality in the US
Saez and Zucman (2016) have access to IRS tax records on capitalincome (yit = ritwit), but wealth data are not available
They impute wealth using a capitalization method, imposing returnsheterogeneity (within broad asset classes):
wit =yitrt
If there is returns heterogeneity, and in particular a positivecorrelation between returns and wealth, the capitalization methodoverstates the extent of wealth inequality and concentration
If the correlation increases over time, the rise in wealth inequality andconcentration may also be overstated
In our Norwegian data we can compare actual wealth inequality withimputed wealth inequality

Theoretical Results
With independence between returns to wealth and wealth levels, bothGini and top wealth shares are overstated Result 1
With correlation between returns to wealth and wealth levels, Gini stilloverstated, while top wealth shares may be overstated or understateddepending on the sign of ρ Result 2
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
How large are the biases in practice?
We replicate Saez and Zucman’s capitalization approach to imputewealth (excluding housing, which is of higher quality only after 2010)in the Norwegian case
We then compute Gini indexes, and shares of wealth owned by thetop 5%, 1%, 0.1%
Results:
Gini indexes systematically overstate the degree of wealth inequalityFor top shares, results depend on how far in the tail we go
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Gini
The Gini based on imputed wealth captures suffi ciently well thelong-term trends in actual wealth inequalityHowever, it overstates true inequality by a 1.05 factor on averageIt tends to do significantly worse in the middle of the sample perioddue to the introduction of a shareholder tax in 2006 (with someannouncement effects at work since 2001)
A. Fagereng, L. Guiso, D. Malacrino, and L. Pistaferri Returns Heterogeneity
Top shares
The evidence on top shares is more nuancedThe larger the share we consider, the larger the overestimationHowever, the degree of overestimation declines if we consider smallerand smaller fractiles

Between 1978 and 2012, the top 0.1% wealth share increases by 15p.p. in the US (Saez and Zucman, 2015)
An increase in the correlation between wealth and returns mayoverstate the increase in wealth concentration at the very top (i.e.,∆ρ = 0.07)

Serial correlation?
From uit = fi + εit , additional persistence in returns may in principlecome from εit
We plot E (∆uit∆uit−s ) = E (∆εit∆εit−s ) for all s ≥ 0
The moments for s ≥ 2 are all economically undistinguishable from 0
Consistent with returns being basically unpredictable once controllingfor demographics and fixed effects

Issue # 1: Snapshot bias
Capital income may partly come from assets sold or purchased overthe year.
Suppose individual has wit = 100 and invests it in a rit = 0.1 CD
In mid-year, she puts extra savings into it (say, 50)At the end of year, we observe yit = 12.5 and wit+1 = 162.5The naive return measure is: rit = 0.125 → too highThe adjusted measure is much closer to actual one: rit = 0.095
Consider again the same starting scenario
But after 8 months, individual cashes half of CD and spends itAt the end of the year, we observe yit = 8.33 and wit+1 = 58.33The naive measure of return is: rit = 0.0833 → too lowThe adjusted measure is again much closer to actual one: rit = 0.105

Offshore Wealth
Potentially important at the top. Can distort measures of wealthconcentration
Alstadseter, Johannesen and Zucam (2015): data from a tax amnestyin Norway
1419 taxpayers disclose assets hidden offshoreNone below the 99th percentile of wealthOnly 12% in the top 0.1% (so not all hide assets offshore)Can potentially understate wealth at the top 0.1% by 4 p.p.
Does this matter for measurement of returns?
If the wealthy hide money offshore to avoid taxes at home, no: ourmeasure of gross returns would be unaffectedIf they invest offshore to grab more favorable returns, our estimates area lower bound of the extent of heterogeneity and correlation withwealth
