What government policies do the most to improve social welfare?

– Should we spend more (or less) on health insurance? – Should we raise top marginal income tax rates? – Should we invest more in children? At what age?

There is existing research analyzing the effect of many of these policy changes

– But little work quantifying the broad trade-offs across policy categories– Often different welfare methods used (CBA, MCPF, cost per life saved…)

This paper: Conducts a unified welfare analysis of historical policy changes in the US over the past half century

– Study 133 policy changes spanning four major categories: Social insurance, education and job training, taxes and cash transfers, and in-kind transfers

A Unified Welfare Analysis of Government Policies

Page 3: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

For each policy change, we draw upon estimates in existing literature to measure:– The benefits to its recipients (measured as willingness to pay) – The net cost to the government (inclusive of fiscal externalities)– We take the ratio of benefits to net cost to form its Marginal Value of Public Funds:

𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 =𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝐡𝑠𝑠′ π‘Šπ‘Šπ΅π΅π‘Šπ‘Šπ‘Šπ‘Šπ΅π΅π΅π΅π‘Šπ‘Šπ΅π΅π΅π΅π‘ π‘ π‘ π‘  𝑑𝑑𝑑𝑑 𝑀𝑀𝐡𝐡𝑃𝑃

𝑁𝑁𝐡𝐡𝑑𝑑 𝐺𝐺𝑑𝑑𝐺𝐺𝐡𝐡𝐡𝐡𝐡𝐡𝑒𝑒𝐡𝐡𝐡𝐡𝑑𝑑 𝐢𝐢𝑑𝑑𝑠𝑠𝑑𝑑

– Differs from traditional benefit/cost ratios by focusing on incidence of costs on government

Comparisons of MVPFs yield social welfare impacts– Suppose Policy 1 has 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀1 = 1 and Policy 2 has 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀2 = 2– More spending on policy 2 financed by less on 1 increases social welfare iff prefer to take $1 from

Policy 1 beneficiaries to give $2 to policy 2 beneficiaries– MVPF quantifies the tradeoffs across policies– Infinite MVPFs correspond to policies that pay for themselves (π‘Šπ‘Šπ‘Šπ‘Šπ‘€π‘€ > 0 and 𝐢𝐢𝑑𝑑𝑠𝑠𝑑𝑑 < 0)

Measuring the Marginal Value of Public Funds

Page 4: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

Construct comprehensive sample of policy changes (more formally, β€œidentification conditions”) from survey and review articles in the four domains

For each policy change, translate estimated impacts into the MVPF

Assess robustness to range of assumptions– Program Parameters (discount rate, tax rate, etc.) – Forecasting/Extrapolation of Observed Effects– Validity of Empirical Designs (RCTs/RDs vs. Diff-in-Diff; Peer Reviewed vs. not; etc.)– Publication Bias (Andrews and Kasy, 2018)– Missing Causal Estimates (e.g. restrict to subsets of policies with different sets of observed effects)

Data and Approach

Page 5: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

Direct investments in low-income children have had the highest MVPFs– High MVPFs throughout childhood: K12, college and health, not just preschool– Many policies β€œpay for themselves” (e.g. 3 out of 4 child Medicaid expansions)– Lower MVPFs for policies targeting adults (MVPFs ranging from 0.5-2)

Several exceptions:β€’ Children: Large variation in estimates with some low MVPFs (e.g. SSI)β€’ Adults: Policies with indirect impacts on children (e.g. Moving to Opportunity)

Library of MVPFs provides tests of a range of theories (optimal taxation, in-kind vs cash transfers, optimal policy targeting, value of correcting market failures…)

Lessons for future welfare analyses– Comparison to traditional Benefit-Cost analysis– Statistical decision theory to quantify value of future work reducing uncertainty

Goal: Illustrate how the MVPF translates β€œreduced form” policy changes into precise statements about the social welfare impact of those policy changes

Define social welfare:

π‘Šπ‘Š = ∫ πœ“πœ“π‘–π‘–π‘’π‘’π‘–π‘–

– 𝑒𝑒𝑖𝑖 is individual 𝐡𝐡’s utility function β€’ Expected future discounted utility (e.g. 𝑒𝑒𝑖𝑖 = 𝐸𝐸[βˆ‘π‘‘π‘‘β‰₯0 𝛽𝛽𝑗𝑗 𝐺𝐺𝑖𝑖𝑑𝑑])

– πœ“πœ“π‘–π‘– is 𝐡𝐡’s Pareto weight– Define πœ‚πœ‚π‘–π‘– = πœ“πœ“π‘–π‘–πœ†πœ†π‘–π‘–, where πœ†πœ†π‘–π‘– is the marginal utility of income– Ratios πœ‚πœ‚π‘–π‘–

πœ‚πœ‚π‘—π‘—correspond to β€œOkun’s Bucket” (Okun, 1976)

General Welfare Framework

Page 9: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

Consider policy change 𝑑𝑑𝑑𝑑 (e.g. change in tax rate, educ. subsidy, etc.)

First-order welfare impact:

π‘‘π‘‘π‘Šπ‘Šπ‘‘π‘‘π‘‘π‘‘ = οΏ½

π‘–π‘–πœ“πœ“π‘–π‘–π‘‘π‘‘π‘’π‘’π‘–π‘–π‘‘π‘‘π‘‘π‘‘ = οΏ½Μ…οΏ½πœ‚π‘π‘ οΏ½

π‘–π‘–π‘Šπ‘Šπ‘Šπ‘Šπ‘€π‘€π‘–π‘–

βˆ«π‘–π‘–π‘Šπ‘Šπ‘Šπ‘Šπ‘€π‘€π‘–π‘– = βˆ«π‘–π‘–

𝑑𝑑𝑒𝑒𝑖𝑖𝑑𝑑𝑑𝑑

πœ†πœ†π‘–π‘–is the sum of WTP by beneficiaries out of their own income for the policy

οΏ½Μ…οΏ½πœ‚π‘π‘ = ∫ πœ‚πœ‚π‘–π‘–π‘Šπ‘Šπ‘Šπ‘Šπ‘ƒπ‘ƒπ‘–π‘–βˆ«π‘–π‘– π‘Šπ‘Šπ‘Šπ‘Šπ‘ƒπ‘ƒπ‘–π‘–

is incidence-weighted average social marginal utility of income

Impact of Policy Change on Social Welfare

Most policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral– Let 𝑅𝑅 denote govt budget and 𝐺𝐺 = 𝑑𝑑𝑑𝑑

𝑑𝑑𝑝𝑝denote impact on govt budget that must be financed

– 𝐺𝐺 includes any fiscal externalities from behavioral responses to the policy

The Marginal Value of Public Funds (MVPF) of policy 𝑑𝑑 is given by:

𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑝𝑝 =βˆ«π‘Šπ‘Šπ‘Šπ‘Šπ‘€π‘€π‘–π‘–

$1 of govt spending on the policy delivers $𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 benefits to the beneficiaries of the policy [Mayshar (1990), Slemrod and Yitzhaki (1996, 2001), Kleven and Kreiner (2006), Hendren (2017)]

– Delivers οΏ½Μ…οΏ½πœ‚π‘π‘π‘€π‘€π‘€π‘€π‘€π‘€π‘€π‘€π‘π‘ in social welfare

Compare Policies by Normalizing by Cost

Page 11: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

Take two (non-budget neutral) policies: policy 1 and policy 2

Consider budget neutral policy, 𝑑𝑑𝑑𝑑: increase spending on policy 1 financed from less spending (greater revenue) from policy 2

To first order, combined policy increases social welfare (π‘‘π‘‘π‘Šπ‘Šπ‘‘π‘‘π‘π‘

> 0) if only if

οΏ½Μ…οΏ½πœ‚1𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀1 > οΏ½Μ…οΏ½πœ‚2𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀2

MVPFs characterize price of delivering welfare to the beneficiaries through the policy– Motivates comparing policies with similar distributional incidence (οΏ½Μ…οΏ½πœ‚1 β‰ˆ οΏ½Μ…οΏ½πœ‚2)– Laffer effect occurs when π‘Šπ‘Šπ‘Šπ‘Šπ‘€π‘€ > 0 and 𝑁𝑁𝐡𝐡𝑑𝑑 𝐢𝐢𝑑𝑑𝑠𝑠𝑑𝑑 < 0 β†’ 𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 = ∞

MVPFs (+ social preferences) are the building blocks for measuring the first-order welfare impact of policy changes

Florida International University (FIU) had a minimum GPA threshold for admission that created a fuzzy discontinuity

Zimmerman (2014) utilizes this discontinuity to examine the impact of FIU admission on earnings for 14 years after admission.

Our estimates are constrained by the existence of previous literature

Would Perry Preschool have been published if the effects were an (imprecise) zero?

Andrews and Kasy (2018) provide a method to test for and correct publication bias

Child Policies: 3-4 times more likely to be published if they find a repayment effect

Adult Policies: up to 12 times more likely to be published if they find a distortionary effect

MVPF estimates contain considerable (model + sampling) uncertainty

The MVPF is a shadow price value to reducing uncertainty

Should govt raise $1 of revenue from known MVPF of 1 to spend on policy j?

Can spend 𝐺𝐺𝑗𝑗 to reduce sampling uncertainty before investing

– E.g. reduce sampling uncertainty from PSID -> Admin data estimates of food stamp intro

Solve for 𝐺𝐺𝑗𝑗 that makes government indifferent to learning

– E.g. food stamps: government WTP $0.24 for every $1 spent on SNAP to learn census vs PSID estimate before deciding to spend

Lesson #3: Use MVPF-Framework to Quantify Value of Future Research

Page 73: A Unified Welfare Analysis of Government PoliciesMost policies (i.e. reduced-form variations, 𝑑𝑑𝑑𝑑) are not budget neutral – Let 𝑅𝑅denote govt budget and 𝐺𝐺=

Direct investment in low-income children have had highest, often infinite, MVPFs– Policies often pay for themselves

Lower MVPFs for policies targeting adults – Costly to redistribute from rich to poor adults– Investment in children has historically been efficient method of redistribution

Lessons for future welfare analyses– Incidence on the government matters (difference relative to CBA)– Design RCTs where WTP can be measured, not just costs– High value to identifying long-run earnings effects, especially child spillovers
