Understanding economic systems is crucial for grasping macroeconomic behavior and policies. Each economic system shapes how resources are allocated, how goods and services are produced, and how the wealth of a nation is distributed. In this chapter, we will explore different economic systems, their characteristics, and their implications for macroeconomic outcomes. We will also examine real-world case studies to understand how nations transition between systems and the macroeconomic effects of these changes.
Macroeconomic Implications
Economic systems define the rules for the production, exchange, and distribution of goods and services in a society. Macroeconomics studies these systems to evaluate their efficiency, equity, and ability to handle shocks like global recessions or pandemics. Understanding these systems helps students analyze the successes and failures of economies worldwide.

- Market Economies
- Mixed Economies.
- Economically Free Economies
- The Welfare Economic System
1. Command Economies
Command economies are systems where the government controls all major economic activities. Central planning authorities decide what to produce, how to produce, and for whom to produce.
Characteristics of Command Economies
Command economies are defined by the centralized control of economic activities. The government owns resources and manages production, pricing, and distribution. Below are the key characteristics of command economies:
- Government ownership of resources.
- Fixed production targets and quotas.
- Limited consumer choice.
- Price controls instead of market-determined pricing.
1. Government Ownership of Resources
In a command economy, the government owns and controls all natural and capital resources. Private ownership is either heavily restricted or absent.
Case Study: Cuban Nationalization (1960)
In 1960, Cuba’s government, led by Fidel Castro, nationalized all major industries, including sugar production and banking.
- Impact: Government controlled exports, especially sugar, which accounted for 80% of the country’s trade at the time.
- Outcome: Though it reduced foreign influence, it led to inefficiencies and reduced production quality.

2. Fixed Production Targets and Quotas
Central planners decide the amount of goods and services to produce, aiming to meet national priorities.
Case Study: Five-Year Plans in the Soviet Union (1928-1991)
The Soviet Union implemented multiple Five-Year Plans to control industrial production. The first plan (1928-1932) prioritized heavy industries like steel and coal.
- Facts: By 1932, steel production increased by 50%, and coal output doubled. However, consumer goods were neglected.
- Outcome: While industrial targets were met, shortages in essential items like food and clothing emerged, affecting living standards.
- Source: BBC History
3. Limited Consumer Choice
Command economies restrict the variety of goods available. Consumers often face limited options as production focuses on meeting quotas rather than demand.
Case Study: North Korea’s Food Supply System (1990s)
North Korea experienced a famine in the 1990s due to mismanagement of agriculture and strict rationing.
- Facts: Citizens were allocated fixed amounts of rice and other staples. Luxury goods were unavailable to the general public.
- Outcome: The lack of consumer choice, combined with natural disasters, led to severe food shortages and an estimated 2 million deaths.
- Source: World Food Programme
4. Price Controls Instead of Market-Determined Pricing
Governments in command economies set prices to maintain affordability, often ignoring market forces.
Case Study: Venezuela’s Price Controls on Food (2003-2015)
In 2003, Venezuela implemented strict price controls on basic goods like flour and milk.
- Facts: Prices were set below production costs to make goods affordable. However, producers incurred losses, leading to shortages.
- Outcome: By 2015, shelves in grocery stores were empty, and citizens waited in long lines for essential goods.

Examples of Command Economies
Former Soviet Union
The Soviet Union operated a command economy for decades. Centralized decision-making led to rapid industrialization but also inefficiencies like shortages and low-quality goods.
North Korea
North Korea remains a command economy with strict government control. Economic isolation has resulted in severe inefficiencies, low living standards, and chronic shortages of basic goods.
Hence
While command economies aim for equity and stability, real-world examples reveal inefficiencies and hardships. Nationalized resources often lead to mismanagement, fixed quotas ignore actual needs, limited consumer choice frustrates populations, and price controls disrupt the market balance. These examples highlight the challenges faced by command economies globally.
2. Market Economies
Market economies rely on free-market principles, where supply and demand determine production and prices. The government plays a minimal role, focusing mainly on enforcing laws and property rights.
Characteristics of Market Economies
Market economies operate on the principles of supply and demand. Decisions about production and pricing are driven by competition, profit, and consumer preferences. Below, we discuss the key characteristics of market economies:
- Private ownership of resources.
- Profit-driven production.
- High consumer choice.
- Competitive markets.
1. Private Ownership of Resources
Individuals and businesses own land, factories, and other resources in the market economies. They control production and make decisions to maximize their benefits. Lecture 13: Oligopoly

Hence
Market economies rely on private ownership, profit incentives, consumer choice, and competition. These characteristics promote innovation and growth, as seen in examples like Microsoft, Apple, and the textile industries of Bangladesh. However, they also require safeguards to ensure fair competition and address potential inequalities.
3. Mixed Economies
Mixed economies combine elements of both market and command systems. The government regulates key sectors while private enterprises drive other areas.
Characteristics of Mixed Economies
Mixed economies blend elements of both market and command systems. This balance ensures economic efficiency while addressing social needs. Below, we explore the characteristics of mixed economies:
- Coexistence of public and private sectors.
- Government interventions in strategic industries.
- Social welfare programs.
1. Coexistence of Public and Private Sectors
In mixed economies, both the public and private sectors contribute to economic activities. The private sector focuses on profit-driven enterprises, while the public sector provides essential services.
Case Study: Malaysia’s Economic Growth (1980s-Present)
Malaysia’s mixed economy relies on both state-owned enterprises (SOEs) and private businesses.
- Facts: The government controls key sectors like energy (Petronas), while the private sector dominates industries like electronics and palm oil. In 2020, Malaysia’s GDP was $336 billion.
- Outcome: This coexistence has helped Malaysia become one of Southeast Asia’s most developed nations, reducing poverty significantly.

Real-world examples from Singapore, Chile, New Zealand, Rwanda, and Botswana show how these policies lead to innovation, higher incomes, and social progress.
5. The Welfare Economic System: A New Approach
Economic systems worldwide have undergone significant transformations to meet societal needs better. In developing regions like South Asia, a welfare economic system offers an alternative to traditional models by emphasizing social justice, equity, and inclusive growth. Inspired by approaches like the one highlighted in the Welfare Model, this system integrates economic freedom with the ethical obligation to uplift disadvantaged populations.
Characteristics of a Welfare Economic System
A welfare economic system prioritizes the well-being of all citizens, blending elements of market economies and social planning with a focus on equitable development.
Core Principles
- Universal Basic Needs: Ensuring access to education, healthcare, and housing.
- Economic Justice: Reducing income inequality through progressive taxation and redistributive policies.
- Sustainable Development: Balancing economic growth with environmental conservation.
- Community Participation: Empowering citizens to participate in decision-making processes.
The Welfare Economic Model in Action
1. Focus on Education and Literacy
The welfare economic system places education at the forefront of development. For example, the Welfare Model highlights literacy as a cornerstone for reducing poverty and empowering communities.
- Case Example: Finland: Finland’s investment in universal education and teacher training has led to a highly skilled workforce and innovation-driven growth.
2. Healthcare for All
Universal healthcare is another pillar of the welfare economic system. This model emphasizes preventative care and affordable access for marginalized groups.
- Case Example: Sri Lanka: Despite limited resources, Sri Lanka’s government-funded healthcare system has achieved remarkable success in reducing maternal and infant mortality rates.
3. Employment and Economic Stability
A welfare system actively creates jobs by supporting small and medium enterprises (SMEs), investing in public works, and promoting skills development.
- Case Example: Pakistan: Programs like the Benazir Income Support Programme (BISP) aim to reduce unemployment and poverty by offering financial aid to underprivileged families.
4. Tackling Corruption and Inefficiency
Corruption and inefficient resource allocation are significant barriers to welfare system implementation. Policies promoting transparency, such as digital financial systems and e-governance, are essential.
- Case Example: Estonia: Estonia’s digital transformation has minimized corruption, ensuring efficient use of public funds for welfare programs.
Benefits of the Welfare Economic System
- Social Cohesion: By reducing income inequality, the welfare model fosters a more united society.
- Economic Productivity: Healthier and better-educated citizens contribute more effectively to economic growth.
- Resilience Against Crises: Welfare systems cushion economies during global recessions, pandemics, or natural disasters.
- Reduction in Poverty Cycles: Focused policies on education and employment empower future generations to break free from poverty.
Challenges and Solutions
Challenge: Funding Constraints
Developing countries often lack the financial resources for large-scale welfare programs.
- Solution: Progressive taxation and international aid partnerships can bridge funding gaps. We will discuss this section under “Ehsan” during the study of applied Islamic Economics. The “zakat” system and “Qarz E Hasanah” are key to accelerating economic growth and reducing income inequalities.
Challenge: Resistance to Change
Shifting from existing systems to a welfare economic model can face political and bureaucratic resistance.
- Solution: Gradual implementation and pilot projects can demonstrate feasibility and build public trust.
Challenge: Corruption and Inefficiency
Leakages in welfare programs reduce their effectiveness.
Corruption in Developing Countries: Causes, Effects, and Solutions

Corruption in Pakistan: Becoming Common Practice
- Solution: Digital governance tools and anti-corruption frameworks ensure accountability.
Application in Pakistan
Pakistan’s socio-economic challenges, including low literacy rates, poor healthcare access, and unemployment, underscore the need for a welfare economic system. Following the principles of the Welfare Model, the government could:
- Expand Universal Education: Invest in teacher training and infrastructure, particularly in rural areas.
- Enhance Social Safety Nets: Scale up programs like the Ehsas Program to include skills training and job placement.
- Promote Public-Private Partnerships (PPPs): Encourage private-sector involvement in building infrastructure and delivering essential services.
- Adopt Digital Platforms: Use technology to deliver welfare services efficiently and transparently.
Hence
A welfare economic system offers a sustainable pathway to equitable development by balancing economic growth with social justice. By learning from global examples and adapting models like the Welfare Model, nations can address systemic challenges, improve living standards, and foster inclusive prosperity. This approach is especially relevant for countries like Pakistan, where a strategic focus on education, healthcare, and employment can transform lives and uplift entire communities.
The Transition of Economic Sytems
The following case studies illustrate the transition of economic systems from one approach to another. They demonstrate how governments can evolve to meet the needs of their people and adapt to changing requirements. These transformations provide valuable insights into adopting a welfare economic system.
World Around Us:
1. China’s Transformation from Command to Mixed Economy
China’s economic transformation is a textbook example of a command economy transitioning to a mixed model. In the 1980s, under Deng Xiaoping’s leadership, China introduced market reforms.
- Agriculture Reform: Farmers were allowed to sell surplus produce in open markets.
- Special Economic Zones (SEZs): Areas like Shenzhen became hubs for foreign investment.
- Results: China’s GDP grew at an average rate of 10% for decades, lifting millions out of poverty. However, challenges like regional inequality and environmental degradation persist.
2. India’s 1991 Economic Liberalization
India’s economy faced a severe crisis in 1991, with dwindling foreign reserves and rising debt. The government initiated sweeping reforms:
- Reduction of Trade Barriers: Import duties were lowered to encourage competition.
- Privatization: State-owned enterprises were opened to private investment.
- Foreign Investment: Policies were revised to attract multinational corporations.
- Results: India emerged as a major global IT and services hub, but disparities between urban and rural areas remain a concern.
Transition to the Welfare Economic System
Transitioning to a welfare economic system requires balancing economic growth with social justice. Nations must integrate market efficiency with policies aimed at reducing inequality and providing basic needs to all citizens. By learning from past transitions, governments can build frameworks that ensure both prosperity and social well-being. Below, we explore key steps and case studies to illustrate this approach.
1. Emphasize Education and Skill Development
A welfare economic system prioritizes access to quality education for all. Skilled citizens contribute to economic productivity and social progress.

Hence
Adopting a welfare economic system involves significant reforms in education, healthcare, social welfare, and infrastructure. By examining transitions like Thailand’s universal healthcare or Brazil’s cash transfer program, nations can develop policies tailored to their needs. These examples show how combining economic efficiency with social equity creates a balanced and sustainable path for development.
Welfare System Through the Lens of Behavioral Economics
The welfare economics can be studied through the lens of behavioral economics. Traditional welfare economics focuses on how resources can be allocated to maximize social welfare, often assuming that individuals make rational choices.
However, behavioral economics challenges this assumption by incorporating psychological insights into economic decision-making. It recognizes that people don’t always act rationally, and their choices can be influenced by cognitive biases, emotions, and social factors. This adds complexity to the study of welfare economics.
Here are some key areas where welfare economics and behavioral economics intersect:
1. Consumer Preferences
- Traditional welfare economics assumes individuals have well-defined preferences.
- Behavioral economics shows that preferences are often inconsistent, and influenced by factors like framing effects, loss aversion, and present bias.
2. Market Failures
- Behavioral economics can explain market failures that traditional welfare economics cannot. For example, people may overestimate small risks (leading to market inefficiencies) or make decisions based on short-term rewards, even when they harm their long-term welfare.
3. Paternalism
- Behavioral economics justifies some level of paternalism in policy. For instance, it supports government interventions like “nudges” to guide individuals toward decisions that enhance their welfare, even if those individuals don’t act in their long-term best interest.
4. Inequality and Fairness
- Behavioral economics takes into account how people perceive fairness and inequality, which can affect their welfare. For example, individuals may accept income redistribution if they feel the process is fair, even if it lowers their income.
5. Social Welfare Functions
- Behavioral economics can refine the social welfare function by accounting for people’s attitudes towards risk, fairness, and social preferences, which traditional models may overlook.
Challenges in Implementing Welfare Systems with Behavioral Economics
Behavioral economics acknowledges that economic actors don’t always act rationally. This introduces several challenges in implementing an efficient welfare system:
1. Inconsistent Preferences
- Problem: People’s preferences can be inconsistent due to cognitive biases, like present bias (valuing immediate rewards over future benefits). This can lead to suboptimal decisions, like not saving for retirement or overconsuming unhealthy goods.
- Impact on Welfare: If individuals make choices that harm their long-term well-being, a welfare system based on rational choice assumptions may not align with actual needs.
2. Overreaction to Losses
- Problem: Behavioral economics shows that people tend to experience loss aversion, where the pain of losing something is stronger than the pleasure of gaining something of equal value.
- Impact on Welfare: Welfare policies like taxes or redistributive programs may face resistance, as people may overreact to perceived losses (even if they are ultimately beneficial).
3. Nudging and Ethical Concerns
- Problem: While “nudges” (small changes in the way choices are presented) can guide people toward better decisions, they raise ethical concerns about manipulation and paternalism.
- Impact on Welfare: Implementing nudges can be seen as infringing on individual freedom, which might undermine the trust and legitimacy of welfare systems.
4. Misunderstanding of Policy Impacts
- Problem: Due to limited cognitive processing and biases like overconfidence, people may not fully understand the effects of welfare programs. For instance, they may misinterpret the benefits of tax incentives or social safety nets.
- Impact on Welfare: If individuals do not understand or trust the benefits of welfare systems, they may be less likely to support or engage with them.
Overcoming the Flaws to Implement Welfare Systems
To overcome these challenges and design effective welfare systems based on behavioral insights, several strategies can be employed:
1. Designing Better “Nudges”
- Solution: Use nudges in welfare policy design that align with people’s biases while promoting better decisions. For instance:
- Automatic Enrollment: Automatically enrolling individuals in retirement savings plans or health insurance and allowing them to opt out can help overcome present bias and encourage long-term welfare.
- Default Options: Offering default choices (like healthier food options or energy-efficient appliances) that are beneficial to individuals and society can lead to better outcomes without limiting freedom.
2. Simplifying Decisions
- Solution: Simplify the decision-making process to reduce cognitive load. Welfare systems should present information in clear, straightforward ways, helping individuals make better choices.
- For example, providing simple, easy-to-understand tax incentives or benefits can reduce confusion and make people more likely to engage with welfare programs.
3. Addressing Loss Aversion
- Solution: Reframe policies to reduce perceived losses. For example, if taxes are necessary, policymakers can emphasize the long-term benefits or “win-win” outcomes for society (like increased public services) rather than focusing solely on the immediate cost to individuals.
- Opt-Out Mechanisms: People may be more willing to accept changes or contributions (like pension plans) if the default is set in their favor, and they can opt out if they choose.
4. Framing Policies Around Social Preferences
- Solution: People care about fairness and social norms. Welfare systems can be more successful if they emphasize how policies benefit society and reduce inequality.
- Social Proof: Demonstrating that most people participate in a certain program can increase enrollment, as people are often influenced by what they perceive as socially acceptable behavior.
5. Education and Trust-Building
- Solution: Educate citizens about the benefits of welfare programs and the real-world impact of policies. This helps counteract misperceptions or biases regarding the effectiveness of such systems.
- Transparency: Ensuring that welfare policies are transparent and easy to understand builds trust and reduces skepticism about the system’s impact.
Hence
Behavioral economics highlights the real-world limitations of human rationality in economic decision-making. However, by applying behavioral insights to the design of welfare systems; such as nudging, simplifying choices, addressing biases like loss aversion, and improving education and transparency; governments can overcome these flaws and implement more effective, inclusive welfare systems that can improve societal well-being.
Economic systems shape a nation’s growth trajectory and affect every aspect of society. By studying systems like command, market, and mixed economies, you can understand how policies impact wealth distribution, resource allocation, and living standards. Case studies provide insights into the challenges and opportunities of transitioning economies, offering valuable lessons for nations aiming for sustainable development via a welfare economic system. The economic system is applied through an economic model. We have explained it in the previous lectures.
Important Transitions under the Welfare Economic System
1. Production Possibility Frontier (PPF)
This graph represents the Production Possibility Frontier (PPF) under a welfare economic system:
- PPF (Blue Line):
- Shows the maximum combinations of two goods (Good X and Good Y) that an economy can produce using its resources efficiently.
- Inefficient Point (Red):
- Located inside the PPF, representing underutilized resources or inefficiencies in production.
- Efficient Point (Green):
- Located on the PPF represents optimal resource allocation to maximize societal welfare. This is the allocative efficiency point.
- Unattainable Point (Orange):
- Located outside the PPF representing combinations that are impossible to achieve with the current resources and technology.
Key Illustration:
- Allocative Efficiency:
- At the green point, resources are distributed in a way that maximizes social welfare, achieving the balance between equity and efficiency.
- Role of Welfare Economics:
- Welfare policies aim to push inefficient points (like the red point) closer to the PPF through measures such as education, healthcare, and infrastructure development.
This framework helps explain how welfare economics promotes efficiency and equity while highlighting the limits of production capacity.
2. Social Welfare Function (SWF)
The Social Welfare Function is a tool in economics used to evaluate the overall well-being of a society based on the utility levels of individuals or groups within that society. It reflects the preferences of society for equity (fairness) and efficiency (optimal resource allocation).
Key Components
- Utility of Individuals: Measures the satisfaction or benefit individuals derive from resources or goods.
- Equity vs. Efficiency Trade-Off:
- Equity: A focus on distributing resources more equally among individuals.
- Efficiency: Maximizing total societal welfare, often leading to unequal distributions.
Social Welfare Curves
- Social welfare curves, also called social indifference curves, represent combinations of utilities of two individuals (Person A and Person B) that yield the same level of social welfare.
- The shape of these curves reflects society’s attitude towards inequality.
Equilibrium of a Welfare Economy
The equilibrium of a welfare economy is achieved at the point where the PPF is tangent to the highest attainable social indifference curve. This point signifies:
- Efficiency: The economy is operating on its PPF, maximizing the use of its resources.
- Social Welfare Maximization: The point of tangency represents the combination of utilities that maximizes overall social welfare, given societal preferences for equity and efficiency.
Here is a hypothetical graph illustrating the equilibrium of a welfare economy:
- Production Possibility Frontier (PPF): Represents the maximum attainable utilities for Individuals A and B given resource constraints (blue curve).
- Social Indifference Curves (SICs): Represent different societal preferences for balancing equity and efficiency:
- Green: Balanced preference.
- Red: Efficiency-focused.
- Purple: Equity-focused.
- Equilibrium Point: The point of tangency between the PPF and the highest possible SIC (marked with a black dot), representing the optimal allocation of resources that maximizes social welfare.
3. Market Failures and Externalities:
Here is a hypothetical graph illustrating externalities (e.g., pollution) and how welfare economics aims to correct them through interventions such as subsidies:
- Marginal Private Cost (MPC): Represents the cost borne by producers for each unit of output (blue dashed line).
- Marginal Social Cost (MSC): Reflects the true cost to society, including externalities like pollution (red solid line).
- Marginal Benefit (MB): Represents the benefits consumers receive for each unit of output (green solid line).
Key Points:
- Without Correction: The equilibrium occurs where MPC intersects MB, leading to overproduction and ignoring external costs.
- With Correction: Welfare economics uses subsidies or taxes to align private costs with social costs. The new equilibrium is where MSC intersects MB, reducing the externality and achieving a socially optimal outcome.
4. Consumer Surplus and Producer Surplus
Here is a hypothetical graph showing Consumer Surplus and Producer Surplus on a supply-and-demand diagram:
- Demand Curve (blue line): It represents the willingness of consumers to pay for a good at different quantities.
- Supply Curve (green line): It represents the cost of production for producers at different quantities.
- Equilibrium Point (red dot): The point where the supply and demand curves intersect, determining the market equilibrium price and quantity.
Surpluses:
- Consumer Surplus (blue-shaded area): The area above the equilibrium price and below the demand curve. It represents the benefit consumers receive by paying less than they were willing to pay.
- Producer Surplus (green shaded area): The area below the equilibrium price and above the supply curve. It represents the benefit producers receive by selling at a higher price than their cost of production.
Welfare economics seeks to maximize these surpluses to ensure the most efficient allocation of resources and maximize societal benefit.
5. Lorenz Curve and Gini Coefficient:
The graph above illustrates the Lorenz Curve and the Gini Coefficient:
- Line of Perfect Equality: (Dashed): It represents a situation where income is distributed equally across the population.
- Lorenz Curve: Depicts the actual income distribution. The farther the curve is from the line of equality, the greater the income inequality.
- Gini Coefficient:
- Calculated as the area between the line of equality and the Lorenz Curve divided by the total area under the line of equality.
- A value of 0 represents perfect equality, while 1 represents maximum inequality.
- In this example, the shaded light blue area highlights the inequality.
Role of Welfare Policies:
- Redistribution: Welfare policies aim to reduce the gap between the Lorenz Curve and the line of equality, lowering the Gini Coefficient.
- Examples:
- Progressive taxation: Higher income earners pay a larger share of taxes.
- Social transfers: Benefits like subsidies, pensions, and unemployment insurance help the lower-income groups.
These measures bring the Lorenz Curve closer to the line of equality, reducing disparities in income. We will discuss this in detail during the lecture about income inequalities.
Research Suggestion
These targeted research areas can help welfare economists develop comprehensive policies that enhance societal welfare while addressing challenges of equity, sustainability, and resilience.
Behavioral Economics in Resource Allocation:
Investigate how cognitive biases, such as loss aversion and status quo bias, influence production and consumption choices at the PPF boundary. Analyze how nudges or incentives can guide individuals and firms toward efficient allocation.
PPF and Technological Advancements:
Research how breakthroughs in automation, AI, and green technologies can push the PPF outward, enhancing societal welfare. Evaluate policies that encourage equitable access to these technologies to prevent exacerbating inequalities.
Incorporating Equity into PPF Analysis:
Explore how redistributive policies, such as progressive taxation and targeted social spending, affect the efficiency-equity trade-off. Develop metrics to measure welfare improvements beyond economic efficiency.
Gender and Inclusion in Resource Allocation:
Research the role of gender equity in enhancing economic outputs at the PPF. Examine how inclusive policies, such as equal access to education and credit, can shift the PPF outward sustainably.
Environmental Constraints on the PPF:
Analyze how resource depletion and climate change restrict the PPF’s potential. Study policies like carbon taxes and renewable energy subsidies to balance economic growth with environmental sustainability.
Circular Economy and Welfare:
Examine the role of a circular economy—recycling and reusing materials—in expanding the PPF. Evaluate its potential to enhance welfare by minimizing resource scarcity and reducing waste.
Shifts in the PPF During Crises:
Investigate how natural disasters, pandemics, and geopolitical tensions shift the PPF inward by disrupting production and resource allocation. Propose strategies to minimize welfare losses during such crises.
Economic Recovery and PPF Re-expansion:
Study post-crisis recovery strategies that restore and expand the PPF. Focus on the role of targeted investments, such as infrastructure development and skill training, in accelerating recovery while reducing inequalities.
Trade and Production Frontiers:
Research how international trade affects the PPF, particularly for developing nations. Examine how access to global markets influences production capacities and welfare outcomes.
Resilience in Global Value Chains:
Explore how vulnerabilities in global supply chains impact the PPF and propose frameworks for enhancing resilience. Focus on policies that balance globalization benefits with domestic welfare protection.
Automation’s Role in Expanding the PPF:
Analyze the impact of automation and digitalization on production efficiency. Research policies to reduce job displacement while ensuring welfare gains from technological progress.
AI in Welfare Maximization:
