5. Effects on Stakeholders/Market:
   → Households: Better connectivity to urban centers + job markets. Increased travel opportunities foster economic upliftment and regional development.
   → Firms: Boost to tourism and hospitality sectors with improved facilities. Enhanced trade opportunities for businesses using air logistics.
   → Government: Economic growth via expanded transport infrastructure. Higher tax revenues from increased economic activity around airports.

6. Evaluation:
   → Strengths: Regional development through investments + increased efficiency in travel and logistics. Positive spillover benefits to multiple sectors.
   → Limitations: Risks of congestion in urban areas near airports + environmental concerns from increased air traffic.
   → Effectiveness: Demonstrates positive production externality, benefiting the economy broadly. Long-term success depends on addressing environmental trade-offs and urban planning.

2. Positive Consumption Externality

1. Concept: Consumption of COVID-19 Vaccine (Healthcare → Merit Good)

2. Country: India

3. Year: 2021

4. Rate/Amount/Measures: Vaccination Coverage: End of 2021: India administered approximately 1.7 billion vaccine doses, with over 720 million individuals fully vaccinated. Herd Immunity Threshold: herd immunity threshold between 55% and 82%

5. Effects on Stakeholders/Market:
   → Households: Vaccinated ppl: reduced risk of severe illness and mortality from COVID-19. economic relief: enabled safer participation in economic activities → income recovery. HOWEVER, disparities in vaccine access, especially in rural areas → unequal health outcomes.
   → Firms: operational continuity: resumption of business operations → productivity.
   → Government: economic recovery

3. Negative Production Externality

1. Concept: Negative Production Externality from Industrial Pollution

2. Country: United States

3. Year: 2020

4. Rate/Amount/Measures: 41 million pounds of toxic chemicals discharged into the Ohio River Basin. Major pollutant: Nitrates, causing oxygen depletion and algal blooms.

5. Effects on Stakeholders/Market:
   → Households: Health risks + reduced access to safe recreational activities.
   → Firms: Harm to fisheries + reduced agricultural irrigation quality.
   → Government: Increased water treatment costs + challenges in meeting water standards.

6. Evaluation:
   → bad: Persistent pollution + chronic health risks

4. Negative Consumption Externality

1. Concept: Negative Consumption Externality from sugary drinks overconsumption 

2. Country: Malaysia

3. Year: 2024

4. Rate/Amount/Measures: 3.6 million Malaysians, or 15.6% adults, became diabetic. Over half a million malaysians suffer from non-communicable diseases including diabetes, hypertension, high cholesterol and obesity

• Prevalence of overweight and obesity among Malaysian adults has increased from 44.5% in 2011 to 54.4% in 2023.  

5. Effects on Stakeholders/Market:
   → Households: diabetes
   → Firms: 242 beverage products reformulated to contain less sugar under the Healthier Choice Logo (HCL) initiative
   → Government: rise in NCDs increase strain on public hea;lthcare system, increasing government spending 

6. Evaluation:
   → Limitations: bad health :(( 

5. Importance of PED for firms and government decision

1. Concept: Importance of PED for Firms and Government

2. Country: Singapore

3. Year: 2023

4. Rate/Amount/Measures:Tax Hike: 15% increase in excise duty on all tobacco products. Price Impact: Cost per stick rose from 42.7 to 49.1 cents; Marlboro 20-pack increased from S$14 to S$15.52.

5. Effects on Stakeholders/Market:
   → Firms: Tobacco products have inelastic demand (PED < 1), meaning price increases lead to minimal reductions in consumption. Short-term sales decline, but firms maintain revenue as addicted consumers continue purchasing despite price hikes. Firms can adapt by focusing on premium pricing strategies or diversifying product offerings.
   → Government: Capitalizes on inelastic demand to generate an additional S$100 million in annual revenue without a significant drop in tax base. Uses PED analysis to predict limited consumption reductions while achieving public health objectives. Balances public health goals with risks of black markets, as excessively high prices may encourage illicit trade.

6. Evaluation:
   → Strengths: PED analysis enables government to effectively target tobacco for tax hikes, as inelastic demand ensures steady revenue. Firms leverage inelastic demand to sustain revenue while complying with regulatory requirements.
   → Limitations: Inelasticity limits significant reductions in smoking prevalence, especially among heavily addicted consumers. Risk of black markets undercuts both government revenues and public health goals.
   → Effectiveness: PED understanding helps align pricing, tax policies, and public health objectives. Past tax hikes reduced smoking prevalence (from 11.8% in 2017 to 10.1% in 2020), showing limited but measurable impact on consumption. Firms and governments must continuously adapt to changes in consumer behavior and market conditions to balance health goals, revenue, and compliance.

6. Minimum price (effective)

1. Concept: Minimum Price for sugarcane

2. Country: India

3. Year: 2023

4. Rate/Amount/Measures: The government increased the Fair and Remunerative Price (FRP) for sugarcane from ₹305 (2022) to ₹315 (2023) per quintal (100 kg), 

5. Effects on Stakeholders/Market:
   → Farmers: Aimed to benefit more than 5 crore sugarcane farmers and lakhs in the sugarcane sector. It serves to double the income of farmers; 99.5% of dues from the previous sugar season were already provided to farmers ∴ they are receiving the correct money for their labour. This represents a 100.6% profit margin over the production cost of ₹157 per quintal.
   → Sugar Mills: The elevated production costs resulting from the higher FRP impacted profits of sugar mills, especially with the obligation to pay within a short timeframe.
   → Sugar Market: Increased production costs; domestic sugar prices pressured by oversupply; potential for reduced export competitiveness.

6. Evaluation:
   → Strengths: With better crop recovery at higher minimum prices, it will ensure fair compensation for farmers. It’s politically favorable for the government. Also aligns with the government's aim for sustainability with ethanol fuels derived from sugarcane.
   → Limitations: Strains sugar mills due to rising COP; possible delayed farmer payments which could lead to imbalance in supply and demand of sugarcane
   → Effectiveness: While enhancing farmer incomes, the success depends on mills' ability to absorb costs without disruption of supply chain

7. Minimum Price (kind of ineffective)

1. Concept: Minimum Price on Alcohol

2. Country: Scotland

3. Year: 2024

4. Rate/Amount/Measures: 50 to 65 pence per unit of Alcohol. Cider alcohol 2 pounds (2018) → 9.75 pounds (2024)

5. Effects on Stakeholders/Market:

   → Consumers: 13.4% fewer deaths reported in Scotland in 2018 with the previous min price. Reduced alcohol consumption by 3% & led to less alcohol related crime

   → Government: No tax revenue received ∴ policy was easy to implement 

   → Producer: The loss in sales was offset due to an increase in price 

6. Evaluation: 

   → Strengths: Easy to implement since the government does not collect any revenue compared to other policies such as indirect taxes. Generally improved the welfare of society with less hospitalizations, alcohol related deaths and crime. 

   → Limitations: Some of the consumers resorted to cheaper alcohol (spirit). People keep drinking since they have high alcohol dependence (71% of people drink once every week) ∴ hard to deter them from drinking, regardless of high prices.

8. Maximum Price

1. Concept: Maximum Price for offshore wind projects (OWP’s)
   Country: UK

2. Year: November 2023

3. Rate/Amount/Measures: Fixed-bottom OWP’s increased from £44/MWh to £73/MWh. Floating OWP’s increased from £116/MWh to £176/MWh. Done to address rising construction costs in renewable energy and attract investment for Allocation Round 6. 

4. Effects on Stakeholders/Market:
   → Consumers: Will be able to power 8.5 million homes each year and reduce the UK’s need for gas by 39%. Creates enough homegrown clean energy, bringing bills down for families.
   → Economy: Supports PM’s expectation to grow the economy through renewable energy production + jobs and meet UK’s ‘net-zero’ emission targets by 2050.
   → Workers: The evolving sector will create tens of thousands of new ‘green’  jobs by 2030.
   → Government: Has potential to attract a record level of private investment in OWP’s next year, with at least 10 projects likely to be eligible. 

5. Evaluation:
   → Strengths: No need for any subsidies + attracts private investment, easier for government to implement and spend without having to reduce gov budget. Provides affordable electricity & savings to bill-payers + improve energy security & reduce consumer exposure to high, volatile gas prices.
   → Limitations: Potential for higher consumer energy costs in SHORT TERM due to recent rises in financing and supply chain costs which all major infrastructure projects have faced.
   → Effectiveness: Overall, it would ensure the lowest costs for energy for consumers IN LONG RUN, providing a sustainable solution to depleting natural energy sources.

9. Subsidy (effective)

1. Concept: Subsidy (effective)

2. Country: Chinese government 

3. Year: 2016

4. Market: Agricultural market of farmers

5. Rate/Amount/Measures: US$ 212 billion in subsidies, significantly more than American and EU combined.

6. Effects on Stakeholders/Market: 

   → Firms: Subsidies given for cotton - good since they are the world’s largest provider of cotton, even though production costs are high. Subsidies given for fisheries - bad since it led to overfishing - welfare loss = overallocation of resources.

   → Government: China’s budget reduced a lot = opportunity cost

   → International Farmers: African cotton farmers (e.g., Burkina Faso, US$790 per capita income) lost income; global prices fell; 15M reliant on cotton production in sub-Saharan Africa affected.

   → Global Market: Reduced cotton prices; 40% tariffs restricted imports; displaced competitive exports.

   → Consumers: Lower prices and more affordable BUT long-term market diversity reduced due to monopolistic Chinese firms. 

7. Evaluation:

   → Strengths: Boosted domestic food security; supported 2500 fishing vessels; largest global cotton producer.

   → Limitations: Global distortions; African farmers’ exports harmed; West African fish stocks depleted; economic harm to fisherfolk.

   → Effectiveness: Cotton production four times costlier than Africa; US$6 billion annual fisheries subsidies resulted in China’s 42% global fishing share. HOWEVER led to reduced incomes in foreign countries & increased food insecurity in vulnerable regions.

   → Consequences: Domestic farmers gained stability; global farmers, fisherfolk lost income, displaced; markets skewed; inequalities worsened.

10. Subsidy (ineffective)

1. Concept: Production Subsidy

2. Country: United Kingdom

3. Year: 2023

4. Market: Agriculture

5. Rate/Amount: Multiple subsidies totaling over £168 million to support innovation, sustainability, and productivity in farming.

6. Effects on Stakeholders/Market:
   → Farmers: £1,000 annually under Sustainable Farming Incentive (SFI); grants of £35,000–£500,000 for water management to reduce waste and improve irrigation; increased access to £12.5 million for environmental sustainability research; 23 actionable plans for land and nutrient management.
   → Environment: £74 million allocated for slurry infrastructure to cut pollution and enhance nutrient efficiency; hedgerow and grassland management under SFI encouraged protection of natural environment.
   → Government: A step towards sustainable agriculture goals; direct agri-environmental payments increased by 81% (£666 million); effective transition from EU Common Agricultural Policy to local support. However, LOT of opp cost
   → Economy: Agri-food sector GVA reached £146.7 billion, up 6.5%; employment in the sector rose by 5%; food chain productivity increased by 3.7%; improved irrigation and waste reduction bolstered overall efficiency.

7. Evaluation:
   → Strengths: Promoted sustainability and innovation as direct financial incentives enabled farmers to adopt greener practices ∴ protecting the environment while improving agricultural sector revenues. ALSO consumers indirectly benefited from sustainable food systems and reduced environmental degradation.
   → Limitations: High initial costs for government due to opp cost + could lead to overdependence of farmers on these subsidies in the future ∴ less self-sustainable
   → Effectiveness: Best effective in pursuing the SDG’s + protecting the farming industry in the long-term.

11. Indirect tax (effective)

1. Concept: Indirect tax on tobacco products

2. Country: Singapore

3. Year: 2023

4. Rate/Amount/Measures: 15% increase in excise duty on all tobacco products.

5. Effects on Stakeholders/Market:

   → Limitations: Hard to isolate impact, risk of shift to untaxed high-sugar products
   → Effectiveness: Reduced sugar consumption post-tax, long-term health impacts need monitoring
   → Consequences: Consumers paid more but benefited health-wise, manufacturers faced reformulation costs, government achieved revenue goals, public health improved through lower sugar intake

13. Indirect tax (ineffective)

1. Concept: Indirect Tax (Cigarette Tax Proposal)

2. Country: United States

3. Year: 2020

4. Rate/Amount/Measures: Increase from $2.70 to $4.35 per pack; $1.65 hike

5. Effects on Stakeholders/Market:
   → Consumers: Higher costs; expected reduction in smoking, but 3.7% of high schoolers and 10.7% of adults still smoked
   → Government: Projected $103.73M annual revenue; expected $1.44B long-term healthcare savings
   → Public Health: Tax aimed to prevent 23,700 youths from smoking, encourage 46,300 adults to quit, and avoid 18,700 premature deaths

6. Evaluation:
   → Strengths: Increased prices discourage smoking initiation and promote quitting, especially among youth and low-income groups
   → Limitations: Ineffective at significantly reducing overall smoking rates, as 3.7% of high schoolers and 10.7% of adults remained smokers
   → Effectiveness: Limited impact due to cross-border purchasing from lower-tax regions; accessibility of alternatives undermined deterrence
   → Consequences: Consumers faced higher costs, with minimal reductions in smoking prevalence; retailers experienced sales loss to neighboring states; government fell short of expected public health improvements

14. Indirect tax (ineffective)

1. Concept: Indirect Tax (Goods and Services Tax - GST)

2. Country: India

   → Small Businesses: Compliance challenges; increased operational costs; some closures due to inability to adapt
   → Consumers: Higher prices on certain goods; essential items like bicycles taxed at 12%, affecting affordability for low-income groups
   → Government: Aimed to streamline tax structure; faced criticism over implementation issues and economic disruptions

6. Evaluation:
   → Strengths: Unified multiple taxes; intended to increase efficiency and reduce tax evasion
   → Limitations: Aviation services taxed at 15–18%, doubling the earlier rates of 6–9%, slowing growth. Insurance products costlier, with taxes rising by 300–320 basis points. Real estate market projected to decline by 12%, with demand for new homes down due to a 10% increase in costs. Inter-state goods supply faced a proposed 1% non-vatable tax for two years to compensate states for revenue loss.
   → Effectiveness: Revenue Neutral Rate crucial for success, ensuring no revenue loss post-implementation. States' disagreement over uniform implementation and rates caused inconsistencies.
   → Consequences: Small businesses struggled with compliance, leading to closures; consumers bore higher costs on essential services like insurance and real estate; government faced criticism for uneven growth across sectors due to high taxation rates.

15. Carbon tax (pigouvian)

1. Concept: Carbon Tax

2. Country: Singapore

3. Year: 2024

4. Rate/Amount/Measures: Increased carbon tax to S$25/tCO₂e from S$5/tCO₂e (2019–2023), with planned increases to S$45/tCO₂e by 2026–2027 and S$50–80/tCO₂e by 2030. Covers seven greenhouse gases and facilities emitting ≥25,000 tCO₂e annually.

5. Effects on Stakeholders/Market:
   → Large Emitters: ~50 facilities responsible for 80% of emissions face significant operational cost increases. Over time, industries may invest in cleaner technologies or relocate if unable to remain competitive. Risk of delayed adaptation in emissions-intensive trade-exposed (EITE) sectors due to global competition.
   → Households: Electricity tariffs projected to rise ~1% for every S$5/tCO₂e increase; cumulative impacts by 2030 may strain low-income households despite U-Save rebates and energy-efficient appliance subsidies. Behavioral shifts towards energy conservation expected, but their extent depends on household adaptability.
   → Environment: Domestic emissions reductions likely, but progress hinges on large emitters adopting effective mitigation strategies. The 5% offset cap ensures local decarbonization focus but may slow down progress for sectors with limited alternatives.
   → Government: Revenue from the tax to fund sustainable initiatives and green infrastructure, yet challenges remain in balancing environmental goals with industry competitiveness. Long-term success depends on continuous policy alignment with global standards and innovation incentives.

6. Evaluation:
   → Strengths: Gradual tax increase allows adaptation; high coverage (~90% of emissions) ensures broad impact. Policy design aligned with international benchmarks (e.g., South Korea, California), enhancing credibility and global competitiveness. Future increases encourage technological innovation and green investment.
   → Limitations: Risk of carbon leakage in EITE sectors could offset gains; high costs may disproportionately impact smaller businesses and low-income households. The 5% offset cap may limit flexibility for hard-to-abate sectors, slowing progress in challenging areas.
   → Effectiveness: By 2030, emissions are expected to decrease, provided industries transition effectively. Tariff increases may drive widespread adoption of energy-efficient technologies but could also lead to economic strain if adaptation lags. Success relies on complementary measures, such as subsidies for green transitions and market oversight to prevent overcharging.
   → Future Consequences: Likely decline in carbon-intensive activities and improvement in emissions metrics. Potential for higher goods and services costs, with price-sensitive consumers reducing discretionary spending. Long-term economic benefits hinge on whether Singapore can foster innovation to maintain industrial competitiveness while achieving environmental objectives.

16. Minimum wages

1. Concept: Minimum Wage Increase

2. Country: United States (California)

4. Rate/Amount/Measures: Minimum wage for fast-food workers increased to $20/hour for restaurants with 60+ locations, up from previous rates.

5. Effects on Stakeholders/Job Market:
   → Workers: Wages increased by ~18%, improving financial well-being and reducing reliance on government aid.
   → Employment Levels: Fast-food sector reached record high employment of 750,500 jobs by July 2024, though seasonally adjusted data shows a potential loss of ~5,400 jobs.
   → Businesses: Menu prices rose ~3.7%; businesses adjusted by reducing hours or operational changes to manage labor costs.
   → Economy: Reduced income inequality and aimed to lower government support dependency; potential ripple effects on consumer costs and overall economic dynamics.

6. Evaluation:
   → Strengths: Improved financial stability for low-wage workers; challenged the narrative that higher minimum wages cause large-scale job losses.
   → Limitations: Increased menu prices transferred costs to consumers; discrepancies in employment data require further investigation to confirm true impacts.
   → Effectiveness: Achieved primary goal of raising worker pay, but broader impacts on business profitability and economic stability need monitoring.
   → Future Consequences: Long-term outcomes depend on whether the policy fosters sustainable industry practices or pressures other regions to adopt similar measures.

17. Contracting out to private sector (ineffective)

1. Concept: Government Intervention in Response to Public Goods–Contracting Out to Private Sector (ineffective)

2. Country: Ireland

3. Year: 2024

4. Rate/Amount /Measures: Direct Provision system: primarily contracting private entities to manage these centers on a for-profit basis. This approach aimed to provide essential services efficiently by leveraging private sector capabilities. MORE THAN 30 private companies were paid over €10 million by the Government for accommodating Ukrainians and asylum seekers last year

5. Effects on Stakeholders/Market: Households: Residents in Direct Provision centers often faced challenges such as prolonged stays averaging 24 months, limited privacy due to shared accommodations, and restricted access to employment and education opportunities. However, their essential needs like food were met. They got access to medical cards (free access to healthcare) Firms: Private contractors benefited financially from government contracts. Government:  government aimed to meet international protection obligations cost-effectively. Nonetheless, the system faced criticism for its impact on residents’ well-being, prompting plans to replace it with a new International Protection Support Service by the end of 2024.

6. Evaluation: Strengths: Contracting out allowed the government to rapidly establish accommodation facilities for asylum seekers, utilizing private sector resources and expertise. Limitations: profit-oriented nature of private management → concerns abt service quality, living conditions, overall resident welfare.
