I Saw a Set of Interesting Papers Last Week
The 2009 "Cash for Clunkers" program (Atif Mian, Berkeley, andAmir Sufi, Chicago Booth School).
Use cross-community variation in the fraction of "clunkers" driven in aMSA (CBASA). Analyze car sales conditioning on X ′s and the fractionof clunkers. Saw a big, positive correlation, so that the programincreased car sales by 360,000 in July-August, 2009. The effects ofthe program appeared to be completed reversed by March 2010 (7months latter). There was no discernible effect on employment, houseprices, or household default rates, except, perhaps, in communities thatmade automobiles.

"Do Expiring Budgets Lead to Wasteful Year-End Spending?Evidence from Federal Procurement" (Jeff Liebman and NealeMahoney).
Spending in the last week of the fiscal year is 4.9 times higher than therest-of-year weekly average. Quality scores of the IT spending in thelast week are 2.2 to 5.6 times more likely to be below the central value.You can do a study like this! See http://www.data.gov/ and/orcontracts at http://www.usaspending.gov/ and/orhttp://www.itdashboard.gov/Amazing data resources for the entrepreneurial student. Think aboutcollaboration!

Interesting Papers Last Week, #3
"The Price Effects of Cash Versus In-Kind Transfers" (Jesse Cunha,Naval Postgraduate School; Giacomc De Giorgi, Stanford; and SeemaJayachandran, Stanford).
Uses interesting data from a field experiment in Mexico. But it showsan important difference between cash and in-kind transfers of food.Cash transfers increase prices (by increasing demand for products).In-kind will result in lower prices, since they increase supply, whichshifts some surplus from producers to consumers. In their case study,they find these price effects are large (the price effects of the in-kindprogram increase net transfers by 12 percent; the price effects for thecash program dissipates 11 percent of the transfer).

Start with Chetty and Saez, August 2005 QJE
Dividend taxes on the highest MTR households fell from 35 percentto 15 percent.
Proposed on 1/7/03. Signed into law 5/28/03, but made retroactiveto 1/1/2003.
This paper is an event study, examining how dividend payout policy isaffected by the change in the tax treatment of dividends.
The dividend puzzle: why do firms pay dividends when they couldrepurchase shares (and this give shareholders capital gains treatmenton their income)?
Bernheim and Wantz (AER —signalling explanation) — it’s stillsomething of a puzzle.

Theories of Dividend Taxation
"Old" view
Dividend taxes reduce the net return on investment and hence thesupply of saving (assuming SEs outweigh IEs).Dividend tax cuts increase saving, investment, profits, and dividendpayouts.
New (but really not new), tax capitalization (or trapped equity) view.
Marginal investments are entirely financed by retained earnings (ratherthan by new share issues, which may have "lemon’s issues").Dividend taxes are then capitalized into the value of the firm (equity istrapped). Hence, reductions in dividend taxes will not affect corporatedecisions.Rather, they simply lower tax burdens on individuals who receive them.

Can’t really tell much.
There’s a post-reform bump, but a time series regression that includesasset and earnings doesn’t reveal a significant change.Why the heck is this a QJE paper???Does entry and exit (sample churning) distort time series patterns?

Figure 2 (initiations)
A substantial, statistically significant number of firms started payingdividends following the 2003 change.
The result is robust (and identical) in a specification that conditions onmany factors thought to influence dividend payouts.
Figure 3 (by month) shows the same thing.
Initiations went from roughly $13 million per quarter (prior to the taxchange) to $205 million per quarter after the reform.The 6 largest quarterly initiation amounts since 1990 took place afterthe tax change.

Figure 5
There was a sharp uptick in the number of firms that increased theirdividends by 20 percent or more.
This is evidence on intensive margin changes
One can’t help but conclude that something happened. Was the taxcut the causal force behind the dividend changes?
JK Scholz ()Dividends - Human Capital 10 / 16
Did Tax Cuts Cause the Dividend Changes?
There was a truckload of corporate scandals in 2001-03, largelyinvolving accounting fraud.
Perhaps this lead to shareholders being worried about management,and therefore forcing firms to get money quickly out of the firm (viadividends).
It turns out that only dividends income distributed to individualsthrough non-tax-favored accounts was affected by the reform.Dividends distributed to pensions, for example, didn’t change.
Use Thomson financial data on institutional ownership. Look atcompanies controlled by insurance companies, pensions, non-profits,etc.In Table 3, diff-in-diff estimates show that the significant increase ininitiations only apply to the companies not controlled by "unaffectedentities."
JK Scholz ()Dividends - Human Capital 11 / 16
Which firms responded?
An executive who holds a large stake in the company experiences alarge change in personal tax payment from a dividend payout. Anexecutive with no shares doesn’t experience any change.
Figure 7 breaks firms into quintiles of share ownership: sure enough,dividend changes are largest for companies with the largest shareownership.
Executives with large stock options are hurt by dividend payouts,since they will lower the value of the firm and hence make it less likelythat the options will be valuable.

Agents and Principals
A literature argues that there is an association between the presenceof a large individual or institutional shareholder and the degree towhich firm behave in a value-maximizing fashion.
The literature looks at a) institutional ownership and b) the existenceof a large, unaffi liated director.
Figure 8 shows institutional ownership matters. But either a largeinstitutional owner or an independent director is suffi cient.
"Our results show that principal-agent issues play a first-order role indetermining behavioral responses to taxation and should be explicitlyincluded in models of optimal dividend taxation."
There is no obvious substitution of dividends for share repurchases,though the counterfactual (would share repurchases have exploded)cannot be ruled out.

Conclusions
Total dividends by nonfinancial, nonutility companies increased by 20percent within 6 quarters of the tax change.
No conclusive proof for either the old view or the new view, though theresults are probably closer to the old view, in that taxes do seem tomatter (though the response is very fast).They call for a theory of dividend behavior that incorporatesprincipal-agent relationships.Perhaps one could get leverage from comparisons of C- and S-Corps,since S-Corps are unaffected. Moreover, one might be able to look atother margins, like investment. How do the dividend tax changesaffect investment?

A New Test of Borrowing Constraints forEducation
Meta Brown John Karl Scholz Ananth Seshadri
New York Fed (Brown) and the University of Wisconsin - Madison
December 11, 2009
What is this paper about?
Going back at least to Becker (1967), economists haveworried that borrowing constraints may impede efficienthuman capital investment.
But the large literature on the topic does not focus on thefamily’s ”expected family contribution” (EFC) – the differencebetween the cost of attending college and what federalformulas determine is the family’s adjusted available incomefor college.
The EFC, however, is neither legally guaranteed noruniversally offered.
Children whose parents refuse or are unable to make their EFCmay face financial constraints in attending college.
Anecdotal EvidenceFrom the Becker-Posner blog
“Currently if you are under 25 and not in graduate school you areconsidered dependent on your parents’ income and have to includetheir income on your FAFSA which will count against you whenfiguring your expected family contribution. For those of us who didnot receive any financial support from parents other than cosigningloans this is a real kick in the ass. Not only is my family lowermiddle-class and unable to contribute to my education, but thegovernment will tell me that they expected them to contribute andwill punish me by lowering my available loans total.”
Posted by Diana on January 11, 2005 at 11:10am in response to”Government’s Role in Student Loans-BECKER”
Our New ApproachKey assumptions
It is difficult to study the EFC directly. One problem, forexample, is that it is difficult to determine what a parentwould have contributed to a child that does not go to college.
For the EFC to matter, there must be some scope fordisagreement between parents are children. Parents withcollege-age children typically have extensive access to credit.With unitary household preferences, contracts could be madebetween parents and children to repay loans made by parents.
There is considerable evidence against key implications of theunitary model of intergenerational relationships (for example,Altonji, Hayashi, and Kotlikoff, 1992).
If children and parents can write legally binding contracts,where the parent pays for the child’s college and the childrepays the loan with interest, our paper is less interesting.
Our New ApproachThe world we’re living in: children and parents may not always agree
If parents and children are independent decision-makers, weknow college-age children are likely to be constrained sincethey generally cannot borrow against future human capital. Arelevant question in this context is whether parents choose torelieve the constraint?
HRS parents report that 33% of their children who went tocollege did so without their financial backing.
25 percent (16 percent) of children whose parents had$200,000 to $400,000 (over $400,000) of net worth in 2000received no parental financial support for college.
Our New ApproachFinancial aid policy assumes parents make their EFC
U.S. financial aid policy (like the prior academic literature onborrowing constraints for education) assumes that parents who areable to pay for college are willing to pay for college:
Students’ access to federal loans and grants is contingent onparents’ income and assets.
But parents are under no legal obligation to make their”Expected Family Contributions” (EFCs).
The standard for students to be independent is strict: Namely,the child needs to be an orphan, veteran, parent, 24 or older,a grad student, or married.
Do borrowing constraints affect the educational attainment ofstudents whose parents do not meet their EFCs?
Our New ApproachA simple analytic model points to a new way to examine this issue
We model interactions between parents and children as adynamic non-cooperative game, following the intuition ofBruce and Waldman (1991).
Parents care about their own consumption and their children.Children, however, care only about their own consumption(”one-sided” altruistic preferences).
Our New ApproachA simple analytic model points to a new way to examine this issue, part 2
There are two regions to the equilibrium of our model.
In one, parents make post-schooling cash transfers. Childrenachieve the efficient level of education. Financial aid will haveno effect on educational attainment.In the other, parents do not make post-schooling cashtransfers. Children do not (or are less likely) to achieve theefficient level of education. Financial aid will, therefore, affecteducational attainment.
The model tells us how to split the data and where to look forevidence for credit constraints. As I will describe, there isconsiderable empirical evidence that we think is consistentwith the presence of borrowing constraints for children infamilies where parents are unwilling or unable to makepost-college transfers.
ModelObjectives, constraints and timing
Preferences
Uk(ck1 , ck
2 ) = u(ck1 ) + βu(ck
2 )
Up({
c it
}i=p,k; t=1,2
)= u(cp
1 ) + βu(cp2 ) + αUk(ck
1 , ck2 )
Physical capital: ai invested in 1 returns Rai in 2 for i = p, k
Human capital: ep & ek returns h(ep + ek + τ) to the child in pd 2
Choices, constraints & timing:
In 1 Parent moves, choosing cp1 + g1 + ep + ap ≤ xp; g1, e
p ≥ 0.
Child chooses ck1 + ek + ak ≤ g1; ak , ek ≥ 0.
In 2 Parent chooses cp2 + g2 ≤ Rap;
Child consumes ck2 = Rak + h(e) + g2.
Period 2There is a discontinuity in optimal second period transfers
Parent maxg2≥0
{u(Rap − g2) + αu(Rak + h(e) + g2)
}
g2(RaP ,Rak +h(e)) =
g2 s.t. u′(Rap − g2) = αu′(Rak + h(e) + g2)
where u′(Rap) < αu′(Rak + h(e))0 otherwise
(1)
Second period transfers are compensatory, since they decrease withthe child’s income and assets.
Period 1Children may overconsume and credit constraints for college may arise rationally
Child’s Euler equation
u′(ck1) = β max
{R, h′(e)
} (1+
∂g2
∂(Rak + h(e))

We show ek= ak= 0. There are two cases to consider. Wheng2> 0
u′(cp1) = αu′(ck
1); u′(cp1) = βRu′(cp
2); (3)
h′(e) = R; u′(cp2) = αu′(ck
2)
If g2 ≥ 0 binds, however
u′(cp1) = αu′(ck
1); u′(cp1) = βRu′(cp
2); u′(ck1) = βh′(e)u′(ck
2 );
h′(e) > R; u′(cp2) > αu′(ck
2 )
Description of equilibriumTwo regions based on whether second period transfers are made
Partition the xp × α× h space into 2 regions
Region 1
→ xp and/or α large and/or h′(·) to R quickly
→ g2 > 0, h′(e) = R
→ Strategic concerns; efficient HC investment
Region 2
→ xp and/or α small and/or h′(·) to R slowly
→ g2 = 0, h′(e) > R
→ No strategic concerns; but underinvestment in HC
When does financial aid matter?Our central Proposition
Proposition 2: In any equilibrium in which g2 > 0, ∂(ep+ek )∂τ = −1.
Financial aid does not influence totaleducational attainment.
In any equilibrium in which g2 ≥ 0 binds,∂(ep+ek )
∂τ > −1. Financial aid increases totaleducational attainment.
Empirical strategyOur model calls for data on parent-child pairs, g2, and financial aid
The model implies the response of educational attainment tofinancial aid should differ for g2 > 0 and g2 = 0 families.
No data set we know contains full financial aid information,realized educational attainment, and post-schooling transfers.
However, we can go to the HRS for educational attainmentand post-schooling transfers, if we can find an informativefinancial aid proxy.
A consistent feature of U.S. federal aid formulas generatessubstantial aid variation with family structure:
EFC(I,A) calculated at the parent level
At the student level, Aid = COA -EFC(I,A)
NTherefore a student’s federal aid can vary substantially withthe number of siblings he or she has in college.We use birth spacing as a proxy for financial aid.
Is Birth Spacing a Reasonable Proxy for Financial Aid?Evidence from the NLSY-97 suggests it is

The Data Used to Examine Our Central PropositionThe Health and Retirement Study
U.S. national panel study initiated in 1992.
Cohorts: HRS (born between 1931-1941); in 1998 additionalcohorts were added, including the AHEAD (born before 1923);CODA (1923-1930); and War babies (1942-1947).
For much of the analysis we start with 13,091 families in the1998 HRS. We restrict the sample by requiring:
Those with complete information on the child’s DOB,education, gender, gift information, and relationship to theHRS respondent.Children who are 24 or older in 2000 with at least one siblingThe main sample is reduced to 9,471 families with 34,593children.The module sample (see next slide) goes from 427 families to334, with 1,262 children.
HRS Measures of Post-College TransfersThe HRS poses two specific, gift questions that are useful to this study
We rely on transfers reported by parents over the period 1998-2004in response to the Waves 4, 5, 6 & 7 questions:
”Including help with education but not shared housing or sharedfood (or any deed to a house), in the last 2 years did [theRespondent or Spouse] give financial help totaling $500 or more toany of their children or grandchildren?”
An even more ideal question was asked of a smaller group ofrespondents in the 1994 Wave 2 Transfers Module:
“Other than contributions toward education expenses, have youever given substantial gifts to your grown children?”
Central Empirical Model
Many observable and unobservable factors influence schoolingdifferences between two arbitrarily chosen individuals, includingparental attitudes and investments in their children, and heritablecomponents of aptitude.
We account for time invariant family-specific factors by estimatingthe following model.
eis = ωi + Xis β + γois + ε is ,
wherei = 1, ...,N familiessi = 1, ...,Si children of family ieis education of child s of family iωi family i fixed effectXis exogenous characteristics of child s of family iois years of overlap in college ages of child s with family i sibs
Central ResultsBirth spacing affects schooling, but only for the no-gift samples

The Results and Next Steps
A student with a sibling 5 years (or more) younger or older,will get roughly one semester less schooling than an otherwiseidentical twin.
Themes and variation
Overlap won’t matter for low-income families (who get fullfinancial aid) or high income families. Use net worth terciles todistinguish groups.Make use of historical changes in financial aid.The margin should be college: it is.Identification in the fixed effects models come from familieswith three or more children. This, in a sense, throws away alot of information. Are results robust to random effects?Split the sample by altruism.
Cross-Child Financial Aid Differences are Likely Small inLow- and High-Income Families
The EFC for high-income families is likely the full cost ofcollege. Therefore, birth spacing will generate no financial aiddifferences for children in these families, since financial aid willbe $0 regardless of spacing.
The EFC for low-income parents is $0. Therefore, birthspacing will also generate no financial aid differences forchildren in these families, since financial aid will be completeregardless of spacing.
We don’t know parental income or net worth at the time thechild attended college.Instead, we separate the overlap coefficients for each parentalnet worth tercile.We expect overlap to matter most (or only matter) in themiddle tercile of the no-gift sample.
Sensitivity AnalysesThe effects hold in the middle net worth tercile of the no-gift sample

Results Should Be Larger When There is More AvailableFinancial Aid
The Middle Income Student Assistance Act of 1978substantially increased financial aid to middle and higherincome families.
We split the sample that includes only students who reachedage 18 by 1978; and those who reached 18 after 1978.We expect overlap in the post-MISAA sample to larger than inthe pre-MISAA sample for the middle tercile of the no-giftsample.

Greater Education Should Be College and Not High School
Overlap is insignificant in the g2 > 0 and g2 = 0 sample ifboth are restricted to those children with high school or lesseducation.
Not surprisingly, the overlap coefficients get substantially largerif high school dropouts are excluded.
Fixed or Random Effects?
The fixed effect estimates are identified off spacing differencesbetween children in families with three of more children.
Children in 2-child families will have identical years of overlap,and hence will be captured by the fixed effect.
Random effects allow us estimate the overlap coefficient usingfamilies with two or more children.
Sensitivity AnalysesResults are robust using cross-sectional variation: the RE estimates

Further Evidence: split the sample on a direct altruismquestion
Would parents give 5 percent of their income to a child with athird, half, or three quarters of the parent’s income?
62 percent of the subsample (914 parents with 3,292 childrenhave useable data) answered ”yes” if their child hadthree-quarters of the parents income. These parents were mostaltruistic.We expect financial aid (and hence overlap) should not matter(or matter less) for the most altruistic families.
We interact the overlap coefficient with three dummies thatseparate the sample by self-reported altruism.
Sensitivity AnalysesAltruism: financial aid matters less for more altruistic families

Conclusions
As we mention at the outset, many prior papers discussborrowing constraints for higher education.
In our framework, all else equal, educational attainment willvary inversely with parental resources for g2 = 0 families.
EFC rises with parental resources. Hence, as income increases,children must finance a greater share of education costs ifparents are unwilling or unable to contribute.
The relationship between education and parental income isdifficult to interpret when studies mix together families willingto meet and unwilling to meet their EFCs.
Conclusions, continued
We develop a theory of human capital investment thatrecognizes the distinct roles of parents and children.
The model reveals an identifiable category of students who arelikely to be meaningfully borrowing constrained.
Estimates using HRS and NLSY97 data are consistent with theexistence of such constraints.
Hence, we think the literature suggesting there are noimportant financial barriers to college is mistaken.
Aid policy is incomplete to the extent that it leaves children ofnoncontributors under-funded.
Policy prescriptions based on these results are unclear:Though increasing financial aid is would move the HC ofnoncontributors’ children toward the efficient level, manychildren of contributors would receive inframarginal subsidies.

What is the Federal EITC?What is the Federal EITC?
It is a refundable tax credit directed primarily at p ylow-income working families.
There is a small credit available to childless taxpayers.There are three ranges to the credit: the phase-in (or subsidy); flat; and phase-out (or clawback) ranges.
C $3 2000EITC is a large program: $31.5 billion in FY2000 (larger than the combined federal spending on food stamps and TANF)stamps and TANF).

Employment elasticities with respect to net income of 0.69 to 1.16.(See Hotz & Scholz, 2003 for full survey of these results.)
All but first two papers use “Diff-in-Diff” approach.

3. We use a different “Diff-in-Diff” identification t t ( t )strategy (cont.)
We systematically “assess” the validity of implication of this identification strategyimplication of this identification strategy
EITC policy “treated” all households with 2 or more children the same (i.e., same credit).So, we should expect to see no difference in outcomes of interest (e.g., employment) between 2+ and 3+ child households.households.

4. Focus on effects of EITC on employment for important population.
Female-Headed households on welfare sometime during 1990s.Look at behavior of these households both on & off of welfareof welfare.Estimating effects of EITC for this population is particularly relevant from public policy perspective.particularly relevant from public policy perspective.

Exploit access to data on federal tax returns for households in sample over 1990s.If our “Diff-in-Diff” identification strategy is isolating EITC effects on employment, should see differential rates of EITC claiming by 2+ vs 1 Kid households rates of EITC claiming by 2+ vs. 1-Kid households before & after expansion.
Our Data Combine Several Ad i i t ti SAdministrative Sources
/Monthly AFDC/TANF case records.Demographic information and benefit receipt.Prior information starting in 1987 on benefits come from Medicaid data.
Q t l d t f UI tQuarterly data from UI system.Measure employment starting in 1986
F d l i f i Federal tax return information. Data from CA Franchise Tax Board beginning in 1990.

Child-only casesCases with more than 2 adults in household
We focus most of analyses on AFDC-FG cases.
SamplingStart random stratified sample of all assistance units on Welfare in California between 1987 & 2000on Welfare in California between 1987 & 2000.
Drawn by Rand for another evaluation. Sample includes ~ 50% of all cases.
Define a “sampling date” – 4th quarter of a household’s spells on welfarehousehold s spells on welfare.
We determine number & ages of children when household on welfare. All cases, on and off welfare, are treated symmetrically. Avoid “overweighting” long-term welfare recipients in our sample.p
Sampling (cont.)
Utilize two samples of households in our analysesCross sectional:
Employment in year following sampling date.This sample mimics repeated cross-section data used in previous studies.
Longitudinal: Employment in periods 3 2 1 and 0 (sampling)Employment in periods -3, -2, -1, and 0 (sampling).Longitudinal data on households allow control for household-specific fixed effects, so focus on within household changes to identify EITC effects.

Empirical Strategy for Understanding the EITC's Effect
Our strategy for assessing validity of estimated EITC’s effect on employmenton employment:
1. Does employment of families with 2+ children increase relative to 1-Kid families? (They should )to 1-Kid families? (They should.)
2. Does employment of 2+Kid families differ from effects for 3+Kid families? (They should not)D t l tt f EITC l i i i l t 3. Do temporal patterns of EITC claiming mirror employment patterns in #1 and #2? (They should)
4. Do see any differences in employment btwn. 2+Kid and 1-Kid h h ld t fili t t ? (W h ld t!)households not filing tax returns? (We should not!)
Similar strategy for #1 - #3 should apply to Claiming EITC.

No qualitative difference in estimated EITC effects on employment or EITC claiming for above variants of our employment or EITC claiming for above variants of our basic results.
Sensitivity Analyses (cont.)y y ( )
Examine EITC effects on household employment and Examine EITC effects on household employment and EITC Claiming for two-parent households on welfare (AFDC-UP cases). (AFDC UP cases).
Do not find any evidence of positive employment effects for AFDC-UP households.Perhaps employment barriers are larger for the subset of UP households with no workers.
Conclusions
W fi d b ff f h diff i l We find robust effects of the differential expansion of EITC btwn. 2+Kid vs. 1-Kid households on employment rates & rates of EITC claiming.gOur identification strategy for identifying EITC effects is validated several different EITC effects is validated several different ways.
Conclusions (cont.)Conclusions (cont.)EITC increased employment for families with 2+ kids b h 3 4 l K d by as much as 3.4 percentage points relative to 1-Kid families.
Ill strationIllustration:11.8% of 31 percentage point employment increase for families with two or more children between 1991 and 2000. Smaller than Meyer & Rosenbaum (2001) or Grogger (2003)
But, another way to look at this is that 77 percent of the differential gain in employment for families with two or more differential gain in employment for families with two or more kids.
Conclusions (cont.)( )Implied Elasticity of Employment w.r.t. household disposable incomedisposable income:
Average EITC differential for families with two or more children was $439 in 1998.$Average disposable income (including transfers) was around $10,000.
The EITC increased disposable income around 4.4 percent.
Employment rates in 1998 were around 60 percent.The EITC increased the relative employment of families with two or The EITC increased the relative employment of families with two or more children 3.2 percentage points, or 5.6 percent.
The implied employment elasticity with respect to disposable i i 1 3 hi h i t d f ti t i EITCincome is 1.3, which is at upper end of estimates in EITC-Effects-on-Employment Literature.
