Supply side economics is a macroeconomic theory that posits that production or supply is the main driver of economic growth.
Aspect
Explanation
Definition
Supply-side Economics, often referred to as trickle-down economics, is an economic theory and policy approach that emphasizes the importance of stimulating the production and supply of goods and services to drive economic growth. It contends that by reducing taxes on businesses and high-income individuals, removing regulatory barriers, and promoting entrepreneurship and investment, the overall supply of goods and services will increase. The theory posits that this increase in supply will lead to economic expansion, job creation, and, ultimately, benefits that “trickle down” to all segments of society. Supply-side economics stands in contrast to demand-side economics, which focuses on managing aggregate demand through government intervention and spending to stimulate economic activity.
Key Concepts
– Supply-side Policies: The implementation of policies aimed at incentivizing production, investment, and entrepreneurship. – Tax Cuts: Reductions in income, corporate, and capital gains taxes to encourage investment and business growth. – Deregulation: Removing regulatory barriers and streamlining business-related regulations to reduce compliance costs. – Laffer Curve: A graphical representation showing the relationship between tax rates and tax revenue, often used to justify tax cuts as potentially increasing revenue through economic growth. – Trickle-down Effect: The belief that benefits from economic growth and increased supply will eventually reach all members of society.
Characteristics
– Pro-Production Policies: Supply-side economics promotes policies that favor production, investment, and entrepreneurship. – Tax Reductions: Reducing tax rates, especially for high-income individuals and businesses, is a central tenet. – Focus on Businesses: A strong focus on businesses as the drivers of economic growth and employment. – Market Efficiency: Belief in the efficiency of free markets in allocating resources. – Economic Growth: The ultimate goal is to achieve sustained economic growth.
Implications
– Economic Growth: Supply-side policies aim to spur economic growth through increased production and investment. – Job Creation: A stronger business environment is expected to lead to job creation. – Income Inequality: Critics argue that supply-side policies may exacerbate income inequality if benefits primarily flow to high-income individuals and corporations. – Fiscal Policy: Supply-side economics has implications for tax policy and government spending. – Laffer Curve: The concept of the Laffer Curve plays a role in shaping tax policies.
Advantages
– Economic Growth: Supply-side economics is associated with the potential for robust economic growth. – Job Creation: Businesses expanding and investing can lead to increased job opportunities. – Innovation: A favorable environment for entrepreneurship can stimulate innovation. – Tax Revenue: Proponents argue that lower tax rates can lead to increased tax revenue due to higher economic activity. – Efficiency: Advocates believe that market-driven resource allocation is more efficient.
Drawbacks
– Income Inequality: Critics contend that supply-side policies may exacerbate income inequality by benefiting high-income individuals and corporations more. – Budget Deficits: Tax cuts without corresponding spending cuts can lead to budget deficits. – Effectiveness: The effectiveness of supply-side policies can vary, and outcomes may not always align with expectations. – Deregulation Risks: Excessive deregulation can lead to market abuses and environmental concerns. – Social Safety Nets: Critics argue that reduced government revenues may strain social safety nets.
Applications
– Reaganomics: The economic policies of the Reagan administration in the 1980s, which included significant tax cuts and deregulation, are often cited as a prominent example of supply-side economics in practice. – Tax Reform: Various countries have implemented tax reforms aimed at reducing rates to stimulate economic growth. – Entrepreneurship Promotion: Many governments create programs and incentives to promote entrepreneurship and business development. – Deregulation Initiatives: Efforts to streamline regulations and reduce bureaucratic hurdles for businesses reflect supply-side thinking. – Investment Promotion: Attracting foreign and domestic investment is a common goal in supply-side economic policies.
Use Cases
– Reaganomics: The economic policies of U.S. President Ronald Reagan, which included substantial tax cuts and deregulation, are a well-known example of supply-side economics in action. – Tax Reforms: Various countries have enacted tax reforms aimed at reducing tax burdens on businesses and high-income individuals. – Start-up Ecosystems: Cities and regions worldwide seek to create favorable environments for start-ups and entrepreneurs. – Deregulation Initiatives: Governments often embark on deregulation efforts to reduce compliance costs for businesses. – Infrastructure Investment: Supply-side thinking can extend to infrastructure projects that facilitate business activities and economic growth.
In essence, supply side economics is concerned with the determinants of productive capacity (output) over time.
The theory is based on the belief that increased production is the best way to drive economic growth.
Production can be stimulated by policies such as:
Deregulation – which removes certain restrictions and lowers the cost of compliance so that businesses are free to explore new opportunities.
Tax cuts – corporate tax cuts enable the company to invest more in hiring workers and capital infrastructure. Income tax cuts, on the other hand, increase the impetus for workers to remain employed and creates more labor output.
Supply side economics is otherwise known as Reaganomics because it formed part of U.S. President Ronald Reagan’s strategy to combat stagflation in the 1980s.
Reagan instituted deregulation, tax cuts, and decreased social spending with the belief that these benefits would “trickle down” from businesses and wealthy individuals to society in general.
In other words, as businesses expanded, they would employ more workers, increase their wages, and put more money in workers’ pockets.
The strategy remained popular in subsequent decades among U.S. Presidents. George W. Bush implemented broad tax cuts between 2001 and 2003 across income, dividends, and capital gains.
In 2017, President Trump cut income and corporate tax rates to stimulate growth and increased tariffs on foreign companies to encourage American manufacturers to produce more.
Is supply side economics effective?
Supply side economics rests on the central tenet that tax cuts for wealthier individuals produce more economic benefit than tax cuts for lower-income individuals.
However, there are two fundamental problems with this idea.
For one, tax cuts for wealthy individuals do not stimulate economic activity or create new jobs.
This is because the extra money tends to be saved, invested, or used to reduce debt. Instead, tax cuts aimed at lower and middle-class earners are a much better way to stimulate macroeconomic activity.
Proponents of supply side economics also believe that tax cuts incentivize workers to earn more money.
In reality, however, studies show that these cuts boost output by increasing discretionary income and thus stimulating demand.
Supply side economics and the Laffer Curve
The Laffer Curve was developed by economist Arthur Laffer in the 1970s. Laffer created the model to show the direct relationship between tax rates and government tax revenue, arguing that each substitutes the other on a 1:1 basis.
The curve showed that a reduction in tax revenue could be offset by the subsequent increase in economic growth which Laffer believed made tax cuts a more prudent policy choice.
Corporate tax cuts faired a little better, with 50% of the loss in tax revenue compensated by increased economic activity.
Case Studies
Reaganomics (United States, 1980s):
Description: Reaganomics refers to the economic policies implemented by U.S. President Ronald Reagan in the 1980s, characterized by tax cuts, deregulation, and reduced government spending. These policies aimed to stimulate economic growth by incentivizing production and investment.
Tax Cuts: Reagan slashed income tax rates, reduced corporate taxes, and implemented capital gains tax cuts to stimulate investment and entrepreneurship. By lowering tax burdens on businesses and individuals, Reagan aimed to spur economic activity and job creation.
Deregulation: Reagan pursued deregulation across various industries, including finance, telecommunications, and energy. By removing regulatory barriers and reducing compliance costs, the government aimed to unleash market forces, promote competition, and enhance productivity.
Impact: Reaganomics contributed to a period of sustained economic expansion, characterized by robust GDP growth, declining unemployment rates, and rising stock markets. While critics argue that the benefits primarily accrued to the wealthy, proponents highlight the overall improvement in economic performance and competitiveness.
Tax Reforms (Various Countries):
Description: Many countries have enacted tax reforms inspired by supply-side economics to stimulate economic growth and competitiveness. These reforms typically involve reducing income tax rates, corporate taxes, and capital gains taxes to incentivize production, investment, and entrepreneurship.
Tax Cuts: Governments implement across-the-board tax cuts or targeted tax relief measures to stimulate economic activity. By lowering tax burdens on businesses and individuals, governments aim to boost disposable incomes, encourage investment, and spur job creation.
Investment Promotion: Tax incentives, such as accelerated depreciation allowances or investment tax credits, are used to encourage businesses to invest in capital assets and expand operations. These incentives reduce the cost of investment and improve the return on investment for businesses.
Impact: Tax reforms aimed at supply-side objectives can enhance business competitiveness, attract investment, and stimulate economic growth. By creating a favorable tax environment for businesses and investors, governments aim to foster innovation, productivity, and job creation.
Entrepreneurship Promotion (Various Countries):
Description: Governments implement policies to promote entrepreneurship and small business development, often inspired by supply-side economics. These policies aim to create a conducive environment for start-ups, encourage innovation, and stimulate economic dynamism.
Start-up Ecosystems: Governments invest in infrastructure, provide access to financing, offer business incubation services, and streamline regulatory processes to support entrepreneurial activity. By fostering a vibrant start-up ecosystem, governments aim to unleash the potential of innovative ventures and new business models.
Tax Incentives: Tax breaks, exemptions, and credits are offered to entrepreneurs and small businesses to reduce the cost of doing business and encourage risk-taking. These incentives may include lower corporate tax rates, tax holidays, or deductions for research and development expenditures.
Impact: Entrepreneurship promotion policies can drive economic growth by fostering innovation, job creation, and competition. By supporting the growth of small and medium-sized enterprises (SMEs), governments aim to diversify the economy, boost productivity, and enhance resilience.
Deregulation Initiatives (Various Countries):
Description: Governments undertake deregulation initiatives to reduce bureaucratic barriers, streamline regulatory processes, and create a more business-friendly environment. Inspired by supply-side economics, deregulation aims to unleash market forces, promote competition, and spur economic growth.
Streamlining Regulations: Governments review and simplify regulations across sectors such as finance, telecommunications, energy, and transportation. By removing unnecessary regulatory burdens, governments aim to reduce compliance costs, enhance efficiency, and encourage investment.
Promoting Competition: Deregulation opens up industries to greater competition by removing entry barriers, monopolistic practices, and anti-competitive regulations. Increased competition can lead to lower prices, improved product quality, and greater innovation, benefiting consumers and businesses alike.
Impact: Deregulation initiatives can stimulate economic growth by fostering entrepreneurship, investment, and market dynamism. By creating a more competitive and efficient business environment, governments aim to spur innovation, enhance productivity, and boost overall economic performance.
Key takeaways:
Supply side economics is a macroeconomic theory that posits that production or supply is the main driver of economic growth.
Supply side economics is otherwise known as Reaganomics because it formed part of U.S. President Ronald Reagan’s strategy to combat stagflation in the 1980s. The idea remained popular with successive U.S. presidents.
Supply side economics believes that tax cuts for wealthier individuals derive the most economic benefit, but in truth, tax cuts for low and middle-income earners are more effective. The ability of supply side economics to compensate for lower tax receipts with higher economic growth is also questionable.
Key Highlights
Supply Side Economics Definition: Supply side economics is a macroeconomic theory that emphasizes the role of production or supply as the primary driver of economic growth.
Focus on Production and Output: Supply side economics centers on the determinants of productive capacity (output) over time and believes that increased production is the key to stimulating economic growth.
Stimulating Production Through Policies:
Deregulation: Removing restrictions and reducing compliance costs to encourage businesses to explore new opportunities.
Tax Cuts: Corporate tax cuts encourage investment in hiring and capital infrastructure. Income tax cuts boost worker employment and labor output.
Origins and Popularization: Supply side economics is also known as Reaganomics due to its adoption in the 1980s by U.S. President Ronald Reagan. It involves strategies like deregulation, tax cuts, and reduced social spending, aiming to stimulate growth by benefiting businesses and wealthy individuals.
Effectiveness of Supply Side Economics:
Tax Cuts for Wealthier Individuals: The theory believes that tax cuts for wealthier individuals have greater economic benefits, but evidence suggests that tax cuts for lower and middle-income earners are more effective in stimulating macroeconomic activity.
Laffer Curve: This model, developed by Arthur Laffer, depicts the relationship between tax rates and government tax revenue. It suggests that lower tax rates can lead to higher economic growth and potentially offset revenue losses.
Critiques and Limitations: Studies show that the efficacy of supply side economics is limited. A substantial portion of income tax cuts may not lead to equivalent economic growth. Corporate tax cuts have a relatively better impact, but their ability to fully compensate for tax revenue losses is still questionable.
The idea of a market economy first came from classical economists, including David Ricardo, Jean-Baptiste Say, and Adam Smith. All three of these economists were advocates for a free market. They argued that the “invisible hand” of market incentives and profit motives were more efficient in guiding economic decisions to prosperity than strict government planning.
Positive economics is concerned with describing and explaining economic phenomena; it is based on facts and empirical evidence. Normative economics, on the other hand, is concerned with making judgments about what “should be” done. It contains value judgments and recommendations about how the economy should be.
When there is an increased price of goods and services over a long period, it is called inflation. In these times, currency shows less potential to buy products and services. Thus, general prices of goods and services increase. Consequently, decreases in the purchasing power of currency is called inflation.
Asymmetric information as a concept has probably existed for thousands of years, but it became mainstream in 2001 after Michael Spence, George Akerlof, and Joseph Stiglitz won the Nobel Prize in Economics for their work on information asymmetry in capital markets. Asymmetric information, otherwise known as information asymmetry, occurs when one party in a business transaction has access to more information than the other party.
Autarky comes from the Greek words autos (self)and arkein (to suffice) and in essence, describes a general state of self-sufficiency. However, the term is most commonly used to describe the economic system of a nation that can operate without support from the economic systems of other nations. Autarky, therefore, is an economic system characterized by self-sufficiency and limited trade with international partners.
Creative destruction was first described by Austrian economist Joseph Schumpeter in 1942, who suggested that capital was never stationary and constantly evolving. To describe this process, Schumpeter defined creative destruction as the “process of industrial mutation that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one.” Therefore, creative destruction is the replacing of long-standing practices or procedures with more innovative, disruptive practices in capitalist markets.
Happiness economics seeks to relate economic decisions to wider measures of individual welfare than traditional measures which focus on income and wealth. Happiness economics, therefore, is the formal study of the relationship between individual satisfaction, employment, and wealth.
An oligopsony is a market form characterized by the presence of only a small number of buyers. These buyers have market power and can lower the price of a good or service because of a lack of competition. In other words, the seller loses its bargaining power because it is unable to find a buyer outside of the oligopsony that is willing to pay a better price.
The term “animal spirits” is derived from the Latin spiritus animalis, loosely translated as “the breath that awakens the human mind”. As far back as 300 B.C., animal spirits were used to explain psychological phenomena such as hysterias and manias. Animal spirits also appeared in literature where they exemplified qualities such as exuberance, gaiety, and courage. Thus, the term “animal spirits” is used to describe how people arrive at financial decisions during periods of economic stress or uncertainty.
State capitalism is an economic system where business and commercial activity is controlled by the state through state-owned enterprises. In a state capitalist environment, the government is the principal actor. It takes an active role in the formation, regulation, and subsidization of businesses to divert capital to state-appointed bureaucrats. In effect, the government uses capital to further its political ambitions or strengthen its leverage on the international stage.
The boom and bust cycle describes the alternating periods of economic growth and decline common in many capitalist economies. The boom and bust cycle is a phrase used to describe the fluctuations in an economy in which there is persistent expansion and contraction. Expansion is associated with prosperity, while the contraction is associated with either a recession or a depression.
The paradox of thrift was popularised by British economist John Maynard Keynes and is a central component of Keynesian economics. Proponents of Keynesian economics believe the proper response to a recession is more spending, more risk-taking, and less saving. They also believe that spending, otherwise known as consumption, drives economic growth. The paradox of thrift, therefore, is an economic theory arguing that personal savings are a net drag on the economy during a recession.
In simplistic terms, the circular flow model describes the mutually beneficial exchange of money between the two most vital parts of an economy: households, firms and how money moves between them. The circular flow model describes money as it moves through various aspects of society in a cyclical process.
Trade deficits occur when a country’s imports outweigh its exports over a specific period. Experts also refer to this as a negative balance of trade. Most of the time, trade balances are calculated based on a variety of different categories.
A market type is a way a given group of consumers and producers interact, based on the context determined by the readiness of consumers to understand the product, the complexity of the product; how big is the existing market and how much it can potentially expand in the future.
Rational choice theory states that an individual uses rational calculations to make rational choices that are most in line with their personal preferences. Rational choice theory refers to a set of guidelines that explain economic and social behavior. The theory has two underlying assumptions, which are completeness (individuals have access to a set of alternatives among they can equally choose) and transitivity.
The peer-to-peer (P2P) economy is one where buyers and sellers interact directly without the need for an intermediary third party or other business. The peer-to-peer economy is a business model where two individuals buy and sell products and services directly. In a peer-to-peer company, the seller has the ability to create the product or offer the service themselves.
The term “knowledge economy” was first coined in the 1960s by Peter Drucker. The management consultant used the term to describe a shift from traditional economies, where there was a reliance on unskilled labor and primary production, to economies reliant on service industries and jobs requiring more thinking and data analysis. The knowledge economy is a system of consumption and production based on knowledge-intensive activities that contribute to scientific and technical innovation.
In a command economy, the government controls the economy through various commands, laws, and national goals which are used to coordinate complex social and economic systems. In other words, a social or political hierarchy determines what is produced, how it is produced, and how it is distributed. Therefore, the command economy is one in which the government controls all major aspects of the economy and economic production.
How do you protect your rights as a worker? Who is there to help defend you against unfair and unjust work conditions? Both of these questions have an answer, and it’s a solution that many are familiar with. The answer is a labor union. From construction to teaching, there are labor unions out there for just about any field of work.
The bottom of the pyramid is a term describing the largest and poorest global socio-economic group. Franklin D. Roosevelt first used the bottom of the pyramid (BOP) in a 1932 public address during the Great Depression. Roosevelt noted that – when talking about the ‘forgotten man:’ “these unhappy times call for the building of plans that rest upon the forgotten, the unorganized but the indispensable units of economic power.. that build from the bottom up and not from the top down, that put their faith once more in the forgotten man at the bottom of the economic pyramid.”
Glocalization is a portmanteau of the words “globalization” and “localization.” It is a concept that describes a globally developed and distributed product or service that is also adjusted to be suitable for sale in the local market. With the rise of the digital economy, brands now can go global by building a local footprint.
Market fragmentation is most commonly seen in growing markets, which fragment and break away from the parent market to become self-sustaining markets with different products and services. Market fragmentation is a concept suggesting that all markets are diverse and fragment into distinct customer groups over time.
The L-shaped recovery refers to an economy that declines steeply and then flatlines with weak or no growth. On a graph plotting GDP against time, this precipitous fall combined with a long period of stagnation looks like the letter “L”. The L-shaped recovery is sometimes called an L-shaped recession because the economy does not return to trend line growth. The L-shaped recovery, therefore, is a recession shape used by economists to describe different types of recessions and their subsequent recoveries. In an L-shaped recovery, the economy is characterized by a severe recession with high unemployment and near-zero economic growth.
Comparative advantage was first described by political economist David Ricardo in his book Principles of Political Economy and Taxation. Ricardo used his theory to argue against Great Britain’s protectionist laws which restricted the import of wheat from 1815 to 1846. Comparative advantage occurs when a country can produce a good or service for a lower opportunity cost than another country.
The Easterlin paradox was first described by then professor of economics at the University of Pennsylvania Richard Easterlin. In the 1970s, Easterlin found that despite the American economy experiencing growth over the previous few decades, the average level of happiness seen in American citizens remained the same. He called this the Easterlin paradox, where income and happiness correlate with each other until a certain point is reached after at least ten years or so. After this point, income and happiness levels are not significantly related. The Easterlin paradox states that happiness is positively correlated with income, but only to a certain extent.
In Economics, Economies of Scale is a theory for which, as companies grow, they gain cost advantages. More precisely, companies manage to benefit from these cost advantages as they grow, due to increased efficiency in production. Thus, as companies scale and increase production, a subsequent decrease in the costs associated with it will help the organizationscale further.
In Economics, a Diseconomy of Scale happens when a company has grown so large that its costs per unit will start to increase. Thus, losing the benefits of scale. That can happen due to several factors arising as a company scales. From coordination issues to management inefficiencies and lack of proper communication flows.
An economy of scope means that the production of one good reduces the cost of producing some other related good. This means the unit cost to produce a product will decline as the variety of manufactured products increases. Importantly, the manufactured products must be related in some way.
Price sensitivity can be explained using the price elasticity of demand, a concept in economics that measures the variation in product demand as the price of the product itself varies. In consumer behavior, price sensitivity describes and measures fluctuations in product demand as the price of that product changes.
