Equity: A Distributional Issue

1. Introduction to Inequity and Equity

In economics, equity refers to the fairness of the distribution of resources, wealth, and opportunities within a society. It is a normative concept, meaning it involves value judgments about what constitutes a just or fair distribution. While economic efficiency aims to maximise the total output or “size of the economic pie,” equity focuses on how that pie is divided amongst the population.

Inequity arises when there is an unfair or unequal distribution of resources, opportunities, and outcomes, leading to significant social and economic disparities. These disparities can manifest in various forms, such as differences in income, wealth, and access to essential services. Inequity is fundamentally a distributional issue that can lead to welfare loss and hinder long-term economic and social development.

1.1 Distinguishing Equity from Equality

It is crucial for economic analysis to differentiate between equity and equality:

• Equality (often referred to as ‘equality of outcome’) implies providing everyone with the exact same amount of resources or treating everyone identically, regardless of their individual circumstances, starting points, or specific needs. It aims for a uniform distribution.
• Equity (often referred to as ‘equality of opportunity’ or ‘distributive justice’) focuses on fairness. It recognises that individuals or groups may have different needs or face different barriers. Therefore, to achieve similar outcomes or opportunities, different levels of support or resources may be required. Equity aims to level the playing field, ensuring everyone has a fair chance to succeed.

Example:

• In the context of public transport, equality might mean providing the same bus pass to every citizen.
• Equity might mean providing a subsidised bus pass or specialised transport services to individuals with disabilities, or to low-income earners, to ensure they have equivalent access to jobs and services, despite their specific challenges.

1.2 Inequity as a Distributional Issue: Manifestations and Measurement

Inequity is a pervasive distributional challenge that leads to significant differences in living standards and life chances. Its primary manifestations include:

• Income Inequality:
  • Definition: The uneven distribution of earned income (wages, salaries, profits, rent, interest) among individuals or households within an economy.
  • Measurement:
    • Gini coefficient: A commonly used measure of income inequality, ranging from 0 (perfect equality, where everyone has the same income) to 1 (perfect inequality, where one person has all the income). A lower Gini coefficient indicates a more equal income distribution.
    • Lorenz Curve: A graphical representation of income distribution, illustrating the cumulative percentage of income held by the cumulative percentage of the population. The further the curve bends from the line of perfect equality, the greater the inequality.
  • Context in Singapore: Singapore’s Gini coefficient before government transfers and taxes was 0.433 in 2023. After government transfers and taxes, it fell to 0.371, indicating that government policies significantly reduce income inequality. The median monthly household income from work (including employer CPF contributions) for resident households was S$10,879 in 2023. For the bottom 10% of households, this figure was significantly lower, illustrating the existing income gap.
  • A widening wage gap is the clearest domestic illustration of the equity problem.

Why graduate and non-graduate wages have diverged in Singapore.

• Wealth Inequality:
  • Definition: The unequal distribution of assets (e.g., property, stocks, bonds, savings, valuable collectables owned by individuals or households. Wealth is a stock, accumulated over time, while income is a flow.
  • Significance: Wealth inequality is often more pronounced and persistent than income inequality because wealth can generate further income (e.g., dividends, rental income), creating a compounding effect and perpetuating intergenerational inequality. Access to wealth also provides greater security and opportunities (e.g., funding for education, starting a business).
  • Context in Singapore: While precise wealth distribution data for Singapore is less frequently published compared to income, global reports often indicate that wealth is more concentrated than income. For instance, according to Credit Suisse’s Global Wealth Report 2023, Singapore had a high proportion of its wealth concentrated in the top decile.
• Access to Essential Services and Opportunities:
  • Education: Disparities in access to quality education (e.g., funding for schools, qualified teachers, enrichment programmes, tuition) can limit future earning potential and social mobility for disadvantaged groups. Those from wealthier families often attend better-resourced schools or have access to private tutoring.
    • Context in Singapore: Despite a strong public education system, disparities in academic outcomes can still be observed. For instance, a study by the Ministry of Education in 2020 found that students from lower-income backgrounds (those living in 1-room and 2-room HDB flats) were less likely to progress to university compared to their peers from wealthier backgrounds.
  • Healthcare: Unequal access to affordable and high-quality healthcare services can lead to poorer health outcomes for lower-income groups, impacting their productivity and overall quality of life.
    • Context in Singapore: While Singapore has a robust universal healthcare system with subsidies (Medisave, MediShield Life, CareShield Life), out-of-pocket expenses can still pose a burden for lower-income families or those with chronic conditions, necessitating further government support.
  • Housing: Unequal access to affordable and adequate housing can lead to substandard living conditions, impacting health, education, and overall well-being.
    • Context in Singapore: Singapore’s public housing (HDB flats) covers about 80% of the resident population, which significantly mitigates severe housing inequality compared to many other nations. However, differences in flat size, location, and the availability of private housing still create wealth disparities related to property ownership.
  • Digital Divide: Unequal access to internet connectivity and digital devices can limit educational and employment opportunities in an increasingly digital world, creating a new form of inequity.

2. Causes of Inequity

Inequity is a complex issue stemming from a combination of economic, social, and political factors:

2.1 Economic Causes

• Market Forces (Demand for Skills and Industries):
  • In a free market economy, the demand for certain skills and the profitability of specific industries determine wage levels. Individuals with highly sought-after, scarce skills (e.g., AI specialists, top financial analysts) command significantly higher wages due to their marginal revenue product.
  • Real-world Example: The rapid growth of the technology and finance sectors globally has led to a substantial increase in demand for specialised professionals, driving their salaries upwards. In Singapore, the average gross monthly income for those in “Information & Communications” was S$8,995 in 2023, while “Accommodation & Food Services” workers earned an average of S$3,000, illustrating this disparity.
• Globalization:
  • Increased competition: Globalisation allows firms to outsource production to countries with lower labour costs, which can lead to job losses or wage stagnation for lower-skilled workers in developed economies.
  • Returns to capital vs. labour: Globalisation can increase the mobility of capital, allowing it to seek the highest returns globally, potentially benefiting capital owners more than labour, thus exacerbating wealth inequality.
  • Real-world Example: While manufacturing jobs have shifted from high-wage economies (like the U.S. and parts of Europe) to lower-wage economies (like China, Vietnam), this has also created new opportunities and lifted millions out of poverty in developing nations. However, it has put downward pressure on wages for some segments of the workforce in developed countries.
• Technological Change:
  • Skill-biased technological change: New technologies often complement high-skilled labour (e.g., IT specialists, managers) while substituting for low-skilled labour (e.g., factory workers, administrative staff). This increases the demand and wages for skilled workers, while reducing demand and wages for unskilled workers.
  • Rise of the “Gig Economy”: While offering flexibility, some gig economy jobs may lack benefits, job security, and consistent income, contributing to precarious employment and widening income gaps for some.

2.2 Social Causes

• Education and Skills:
  • Human Capital Theory: Higher levels of education and specialised skills enhance an individual’s human capital, leading to higher productivity and, consequently, higher earnings. Access to quality education is thus a key determinant of social mobility.
  • Real-world Example: In Singapore, academic qualifications are highly correlated with income. As of 2023, the median gross monthly income for university graduates was S$5,200 compared to S$2,8000 for those with secondary qualifications and S$2,000 for those with primary or no qualifications. Disparities in access to early childhood education and enrichment programmes can create a significant head start for children from wealthier backgrounds.
• Discrimination and Social Exclusion:
  • Definition: Unequal treatment based on characteristics such as race, gender, religion, disability, or age. This can lead to barriers in hiring, promotion, unequal pay for equal work, or limited access to economic opportunities.
  • Real-world Example: While Singapore has anti-discrimination laws, subtle biases can still exist. For instance, while the official gender pay gap has narrowed, statistics from the Ministry of Manpower in 2023 showed that women in Singapore earned 14.3% less than men on average in 2023, largely due to differences in industry, occupation, and working patterns, but also with a smaller portion attributed to unexplained factors that could include discrimination.
  • Social Exclusion: When certain groups are systematically denied full participation in economic, social, and political life due to factors like poverty, disability, or ethnicity.
• Health and Disability:
  • Chronic illness or disability can significantly limit a person’s ability to work full-time or in high-paying jobs, leading to lower income. Additionally, healthcare costs can deplete savings, further entrenching poverty.
  • Real-world Example: In Singapore, individuals with disabilities often face challenges in securing employment. While the government has initiatives like the Open Door Programme to support their employment, the employment rate for persons with disabilities (aged 15-64) was around 30% in 2021, significantly lower than the general population, highlighting this barrier to economic participation.

2.3 Political Causes

• Unequal Political Power and Rent-Seeking:
  • Individuals or groups with significant wealth or influence can lobby governments to enact policies (e.g., tax loopholes, deregulation, favourable contracts) that protect or enhance their economic interests, sometimes at the expense of broader societal well-being or income redistribution. This is often termed rent-seeking.
  • Real-world Example: In many countries, powerful corporations and wealthy individuals contribute significantly to political campaigns, which can lead to policies that favour their industries or reduce their tax burdens, potentially widening the gap between the rich and the poor.
• Weak Social Safety Nets:
  • Insufficient government provision of welfare benefits, unemployment support, or social assistance programmes can leave vulnerable populations without adequate support, allowing economic shocks to quickly translate into deeper inequity.
• Deregulation:
  • Policies that reduce regulation in labour markets (e.g., weakening trade unions, reducing minimum wage protection) can lead to lower wages for some workers and increased profits for capital owners, potentially increasing inequality.
• Taxation and Spending Policies:
  • The design of a country’s tax system (e.g., progressive vs. regressive) and how government revenue is spent (e.g., on universal public services vs. targeted benefits) directly impacts income and wealth distribution.

3. Government Policies to Address Inequity

Governments play a critical role in mitigating inequity through a range of redistributive and opportunity-enhancing policies.

3.1 Redistribution Policies (Adjusting Outcomes)

• Progressive Taxation:
  • Mechanism: A tax system where the marginal tax rate increases as income rises, meaning wealthier individuals pay a larger proportion of their income in taxes. Revenue is then used to fund public services or transfers.
  • Real-world Example: Singapore employs a progressive income tax system, with the highest marginal tax rate for individuals at 24% for incomes above S$1 million (as of YA2024). This ensures that high-income earners contribute a larger share of their income to public coffers, which funds various social programmes for low-income citizens, such as ComCare, which provides financial assistance for basic needs.
• Social Transfers and Welfare Programmes:
  • Mechanism: Direct payments or in-kind benefits provided by the government to low-income households or vulnerable populations. These act as a safety net.
  • Real-world Example: Singapore’s ComCare scheme provides short-to-medium term financial assistance, subsidies for healthcare, education, and childcare for low-income families and individuals. The Workfare Income Supplement (WIS) scheme tops up the wages of lower-wage workers and encourages them to work, providing up to S$4,200 annually in cash and CPF contributions for eligible workers aged 30 and above.
• Minimum Wage:
  • Mechanism: A legally mandated lowest hourly wage that employers can pay. It aims to raise the income of the lowest-paid workers.
  • Real-world Example: While Singapore does not have a universal minimum wage, it implements a Progressive Wage Model (PWM) for specific sectors (e.g., cleaning, security, landscape, retail, food services). The PWM links wage increases to skills training and productivity improvements, aiming to uplift the wages of lower-income workers in a sustainable manner.

3.2 Education and Employment Policies (Enhancing Opportunities)

• Subsidised Education and Training Programmes:
  • Mechanism: Government funding for schools, universities, and vocational training initiatives to ensure access to quality education and lifelong learning for all, regardless of socio-economic background. This enhances human capital.
  • Real-world Example: Singapore’s SkillsFuture initiative provides significant subsidies (e.g., SkillsFuture Credit) for adult learners to acquire new skills, undergo reskilling or upskilling, and improve their employability across various industries. This aims to reduce occupational immobility and income disparity related to skills gaps. Scholarships and bursaries are also extensively provided to students from lower-income families.
• Job Creation and Labour Market Policies:
  • Mechanism: Policies aimed at stimulating economic growth and creating employment opportunities (e.g., investment in infrastructure, attracting foreign direct investment, supporting SMEs). Active labour market policies (e.g., job matching services, career counselling) also help.
  • Real-world Example: The Economic Development Board (EDB) in Singapore actively attracts high-value investments into various sectors, creating diverse job opportunities across different skill levels and contributing to overall employment and income growth.

3.3 Health and Housing Policies (Basic Needs and Security)

• Universal Healthcare and Housing Assistance:
  • Mechanism: Government provision or significant subsidies for essential services like healthcare and housing, ensuring that all individuals, regardless of income, can access basic necessities for a decent quality of life.
  • Real-world Example: Singapore’s Public Housing Scheme (HDB) provides affordable housing to approximately 80% of the population, with significant subsidies and grants for lower-income households. The multi-layered healthcare financing system, including MediShield Life (universal health insurance) and Medisave (compulsory health savings), coupled with substantial government subsidies at public healthcare institutions, aims to ensure that healthcare remains accessible and affordable for all Singaporeans.

4. Trade-offs between Efficiency and Equity

3 Examples of How Achieving Efficiency may lead to Inequity

• 1) Globalisation – freer movement of goods and services, labour and capital internationally promotes economic efficiency. For example, a key theory of international trade, the Theory of Comparative Advantage shows how free trade can allow for productive efficiency (goods are produced in countries that incur least opportunity costs in producing those goods) and allocative efficiency globally as there would be deadweight welfare losses to society if trade restrictions are imposed as free trade actually increases societal welfare. (You will learn all these under International Trade and Globalisation.) Unfortunately, especially in developed economies, globalisation has led to a lot of job losses for the locals due to competition from foreigners. Entire industries may relocate and thus disappear, leaving workers structurally unemployed. Low skilled workers may face intense competition from foreign labour, which will keep their wages depressed whilst high skilled workers see their wages soar as the industries serve a global market and there is higher demand for their skills due to global competition. In short, this means that the income gap widen whilst the economy may be booming due to globalisation and the increased efficiency globally. Widening income gap will lead to issues of inequity as the lower income may be “out-priced” in markets for housing, education etc. You can learn more about how globalisation has led to widening income gap through our Chief Tutor’s explanatory video below.

• 2) To correct the over-consumption of demerit goods, such as cigarettes, indirect taxes may be imposed. However, as indirect taxes are regressive in nature (hurts the lower income more so than high income earners due to higher tax burden as a proportion of income), it may be considered inequitable. Also, as it may cause the lower income to have to forgo other necessities even if they were to cut back on cigarettes. (Counter argument: Since it is a demerit good, it may be a good thing for them if they are forced to completely give up smoking. This can improve their health and increase their productivity, which can help them earn more. This view is of course rather subjective.
  
• 3) In the pursuit of productive efficiency, capital goods and technological advancements may be adopted at the expense of low-skilled workers. Demand for low-skilled workers fall while demand for high-skilled, for example those with robotics programming skills would increase. Once again, this can lead to widening income gap and this issues of inequity.

3 Examples of How Achieving Equity May Lead To Inefficiency

1) A minimum wage is quite common across the world and is a means to reduce the income gap and help enable the lower income to afford necessities and merit goods. However, retrenchments and higher unemployments occur with implementation of minimum wage. This leads to deadweight welfare losses in the labour market and hence inefficiency occurs. (Details are covered under minimum wage topic.)

2)  Food subsidies may be provided to ensure affordability by low income and thus achieve equity. However, this would increase supply (assuming indirect subsidies), leading to an increased allocation of resources to the production of food, than is socially optimal (assuming the free market equilibrium is allocatively efficient). Thus, allocation of resources to food and allocative inefficiency now exists. (More details done in Subsidy and Market Failure topic.)

3) Progressive income tax system is one whereby higher income earners will pay a higher proportion of their income in taxes. This will help reduce the income gap and also yield substantial tax revenues that can be redistributed to the low income earners through transfer payments and subsidies, who can thus better afford necessities. This obviously improves equity but can lead to inefficiency. For example, it can lead to a fall in incentive to work as the marginal tax rate increases as income increases. If skilled labour are now working fewer hours as a result of this, it can be deemed that productive inefficiency is occurring in the economy as scarce resources are not well-utilised and will lead to lower production of goods and services.

5. Conclusion

Inequity is a significant and complex challenge for economies worldwide, as it can hinder economic growth, reduce social mobility, and threaten social cohesion. While the free market is efficient in allocating resources based on demand and supply, it does not inherently guarantee an equitable distribution of outcomes. Governments, therefore, play a critical and active role in addressing inequity. Through a combination of redistributive policies (like progressive taxation and social transfers) and opportunity-enhancing policies (like subsidised education and universal access to essential services), governments aim to ensure that everyone has the resources and opportunities they need to thrive, thus fostering a more inclusive and stable society.

Discussion Questions

1. What is the fundamental difference between “equality of outcome” and “equality of opportunity,” and why is this distinction crucial when discussing government policies to address inequity?
2. Evaluate the potential trade-offs between pursuing greater equity and maintaining economic efficiency. Can policies aimed at reducing inequity ever lead to greater overall economic growth?
3. Beyond income and wealth, discuss how inequity in access to digital resources (the “digital divide”) can exacerbate existing disparities in modern economies. What policies could address this?
4. Using specific examples, analyse the challenges governments face in implementing effective policies to address inequity, considering factors such as political feasibility, administrative costs, and potential disincentive effects.
