SG Talk

The document outlines various measures under Singapore’s SG60 initiative, including vouchers, rental support, cultural initiatives, tax rebates, and philanthropic incentives.

To analyze this using game theory, we can consider the following:

1. Strategic Interactions:

The government, citizens, businesses, and charities are all players with different incentives.

Businesses benefit from increased consumer spending due to vouchers.

Citizens are incentivized to spend within certain sectors (e.g., hawkers, supermarkets).

Charities receive matching funds, motivating increased fundraising efforts.

2. Prisoner’s Dilemma in Philanthropy:

Matching grants encourage donations, but individual donors might hesitate, expecting others to contribute instead.

If all donors wait for others, total giving could decrease despite incentives.

3. Coordination Games:

The success of the SG60 Vouchers depends on citizens actively claiming and using them within the designated time.

If businesses don’t widely accept the vouchers, their utility diminishes, reducing the intended stimulus effect.

4. Incentive Design:

The tax rebate has a cap ($200), benefiting middle-income earners more than high-income groups.

The SG Culture Pass and ActiveSG Credit Top-Up may have limited uptake if not well-publicized.


Weaknesses and Flaws:

1. Short-Term Effect:

The measures focus on immediate economic stimulus rather than long-term structural improvements.

Once incentives expire, spending behavior may revert to previous levels.

2. Inefficiency in Targeting:

Vouchers may not reach those in greatest need effectively, as wealthier individuals also receive them.

A fixed PIT rebate cap might not provide sufficient relief for low-income individuals who pay minimal taxes.

3. Potential for Market Distortion:

Businesses accepting vouchers might raise prices, reducing the actual benefit.

Rental support is uniform rather than need-based, meaning successful businesses receive the same relief as struggling ones.

4. Behavioral Uncertainty:

The success of the philanthropy incentives depends on donor behavior, which is hard to predict.

The cultural and sports credits assume that recipients will engage in activities rather than save them.

Effectiveness Consequences of SG60 Measures

While the SG60 measures aim to stimulate economic activity and social engagement, their effectiveness depends on behavioral responses, market reactions, and unintended consequences. Below is a deeper dive into their potential successes, limitations, and risks through a game theory perspective.

1. SG60 Vouchers – Short-Term Stimulus with Potential Market Distortions

✅ Effectiveness:

Encourages immediate spending, supporting local businesses.

Targets lower- and middle-income groups better than cash handouts (since spending is restricted to certain merchants).


❌ Consequences & Risks:

Inflationary Pressure: Businesses accepting vouchers might raise prices, knowing demand is temporarily boosted.

Substitution Effect: Consumers may shift spending rather than increase it (e.g., using vouchers for essentials but saving their usual cash for discretionary spending, neutralizing the intended economic boost).

Expiration Risk: If people delay usage, the intended stimulus effect may be unevenly distributed over time.


🔍 Game Theory Perspective:

The effectiveness depends on whether businesses see it as an opportunity to compete (lowering prices) or exploit the situation (raising prices).

A commitment mechanism (e.g., businesses must maintain pre-voucher pricing to qualify) could prevent inflationary pressure.

A time-sensitive discount (extra 10% value if spent in the first 3 months) could prevent delayed usage.

2. Personal Income Tax Rebate – Limited Benefit for Lower-Income Groups

✅ Effectiveness:

Provides tax relief to middle-income workers, potentially increasing disposable income.

Simple, automatic, and widely applicable.


❌ Consequences & Risks:

Regressive Impact: A flat $200 cap means a middle-income worker earning $50,000 benefits more than a low-income worker earning $20,000.

Zero Benefit for Non-Taxpayers: Many lower-income earners who pay little or no tax receive no direct benefit.

Unclear Spending Impact: Higher-income individuals may simply save the extra money, reducing the intended economic stimulus.


🔍 Game Theory Perspective:

The income effect suggests that higher-income groups are more likely to save, making the tax rebate less effective as a stimulus.

A tiered tax rebate system (e.g., 80% rebate up to $500 for lower-income groups, but only 40% for higher earners) would increase spending impact where it’s needed most.

3. Rental Support for Hawkers – Potential for Misuse or Price Manipulation

✅ Effectiveness:

Directly helps small businesses reduce costs.

Protects an important cultural and economic sector (hawker centers).


❌ Consequences & Risks:

No Guarantee of Consumer Benefit: Some hawkers may keep prices the same, absorbing the subsidy as profit instead of passing on savings.

Long-Term Market Effects: Landlords may increase rent in the future, knowing that tenants have received government aid.

One-Time Impact: Once rental support ends, struggling hawkers could still face the same financial pressures.


🔍 Game Theory Perspective:

If all hawkers lower prices, they gain more customers (positive-sum game).

If some lower prices while others don’t, those who reduce prices lose revenue while others profit (prisoner’s dilemma).

A conditional rental subsidy (hawkers must maintain or reduce prices to qualify) would align incentives better.

4. SG60 Philanthropy Incentives – Risk of Free-Riding and Uneven Giving

✅ Effectiveness:

Matching grants amplify donations, encouraging higher contributions.

Long-term incentives (3-year commitments) reduce volatility in funding.


❌ Consequences & Risks:

Free-Rider Problem: Some donors might wait for others to donate first, assuming total contributions will be met by others.

Big Donor Bias: The enhanced 1.5x matching for large ($250,000+) donations might benefit corporate donors more than small grassroots givers.

Misdirected Giving: Donors might redirect existing giving instead of increasing total donations (e.g., giving through matched channels instead of their usual causes).


🔍 Game Theory Perspective:

This is a public goods problem, where individuals benefit from the total contribution without necessarily increasing their own giving.

A tiered matching system (e.g., higher match for first-time donors, lower match for large donors) could broaden participation.

A public donation tracker (showing real-time progress toward fundraising goals) could counter the waiting effect by creating urgency.

Final Assessment: Do These Measures Achieve Their Goals?

Key Takeaways:

The vouchers and tax rebates stimulate spending but are not well-targeted to lower-income groups.

The rental support lacks a mechanism to ensure hawkers pass on benefits to consumers.

The philanthropy incentives encourage donations but favor large donors over small grassroots contributions.


🔍 Game Theory-Based Solutions:

1. Time-Sensitive Spending Incentives → Avoid delayed voucher use.


2. Tiered Tax Rebates → Ensure fairness in relief distribution.


3. Conditional Rental Support → Require hawkers to maintain or reduce prices.

4. Balanced Philanthrop
y Matching → Higher incentives for smaller donors to prevent free-riding.
