### Overview and central thesis
- Policy decisions on taxation and public expenditures intrinsically reflect moral choices.
- Economists and public finance practitioners have traditionally emphasized economic efficiency and often avoided moral considerations.
- Recent work by evolutionary moral psychologists suggests policies can be better designed and muster broader support if policymakers consider a full range of moral perspectives on public finance.
- A few pioneering empirical applications of this approach in economics have shown promise.

### Limitations of the traditional economic approach
- Traditional analysis: individuals as the unit of analysis, with relevant characteristics being income, wealth, or spending potential.
- Two reasons for the traditional approach:
  - Economists’ desire to be viewed as objective social scientists.
  - Dominance of WEIRD (Western, Educated, Industrialized, Rich, and Democratic) values in public finance scholarship, emphasizing the golden rule.
- Evolutionary moral psychology challenges the sufficiency of the golden rule by showing moral judgments often arise from instinctive reactions later justified by reasoning (Greene 2013).

### Moral Foundations Theory — six foundations (Haidt 2012)
- (1) Care/harm: sensitivity to suffering; predisposition to care for those in need.
- (2) Fairness/cheating: valuing collaboration and reciprocal altruism; shunning or punishing cheaters.
- (3) Loyalty/betrayal: rewarding team players and punishing betrayal; focused on group membership.
- (4) Authority/subversion: respect for rank and status; sensitivity to proper behavior in hierarchies.
- (5) Sanctity/degradation: disgust at perceived pollution; longing for purity in nature, feelings, and relationships.
- (6) Liberty/oppression: cooperation in hierarchies but readiness to rebel against tyrannical leaders.
- Note: The first two foundations align with WEIRD traditions and the golden rule; the other four can justify treating people differently depending on group membership and other factors.

### Applications to public finance debates
- Two highlighted debates where moral perspectives matter:
  - Policy responses to job losses from automation and globalization:
    - Traditional economist focus: liberalize labor and housing markets to facilitate individual mobility.
    - Moral-perspective insight: supporting communities left behind may better address people’s identification with place and community.
  - Immigration and access to publicly funded services:
    - Traditional analysis: costs and benefits to citizens/residents.
    - Moral-perspective insight: cultural identity and communitarian concerns affect views on immigrant access to services.
- Globalists (universalists) versus nationalists (communitarians):
  - Universalists: altruism/trust unaffected by social distance.
  - Communitarians: altruism/trust decline with social distance.

### Empirical findings and examples
- Enke, Rodríguez-Padilla, and Zimmermann (2020):
  - Suggest the traditional left-right divide is explained by whether individuals’ moral values are primarily universalist or communitarian.
  - NBER Working Paper 27511.
- Klemm and Mauro (2021):
  - Found communitarians’ opposition to progressive taxation declined among individuals directly hurt by the pandemic through job loss or illness.
  - International Tax and Public Finance 28 (Supplement).
- Stantcheva (2021):
  - Using US surveys, shows notions of fairness are more important than views regarding efficiency in shaping attitudes toward progressivity in the taxation of income or inherited wealth.
  - Quarterly Journal of Economics 136 (4): 2309–69.
- Behavioral experiments (Greene 2013):
  - Participants asked to explain controversial policies (single-payer health care, cap and trade) then reassessed their views; confronting lack of understanding led to more moderate positions.

### Design and communication implications for policy
- Policy design:
  - Consider a broader palette of moral perspectives (care, fairness, loyalty, authority, sanctity, liberty) to craft measures that can muster wider consensus.
  - Leverage specific moral foundations for policy framing:
    - Purity/sanctity: present a carbon tax as safeguarding the purity of the earth; emphasize local environmental purity for communitarians.
    - Loyalty: promote national competitiveness in science, technology, or productivity using patriotic sentiments.
    - Authority: use respected figures (context-dependent: police, military, teachers, doctors, the elderly, religious leaders) to deliver messages that resonate with conservative audiences.
  - Analogy examples: balancing the budget likened to putting one’s house in order invokes purity sentiments.
- Role of information:
  - Persuasion presupposes some openness to information; providing factual explanations of how policies work can moderate extreme positions.
  - Survey-based experiments that provide facts and measure opinion changes suggest information can be the beginning of persuasion (Stantcheva 2021).
- Practical recommendation:
  - When considering tax or spending policies, enrich fairness-focused analysis with additional moral perspectives and tailor presentation to citizens with differing moral values to increase acceptability.

### Key takeaways
- Moral perspectives beyond the golden rule (community, authority, divinity/purity, loyalty, sanctity, liberty) are influential in shaping public finance preferences.
- Understanding these perspectives can explain observed political divides and improve policy design and communication.
- Providing factual information about policy mechanics often leads to more moderate public positions and can facilitate persuasion.
- Large-scale empirical studies applying moral psychology to public finance are nascent but promising; incorporating these insights is a practical starting point for policymakers.
