10.3 - Taxation & Government Spending
How government spending affects the economy
Governments use spending as a tool to shape economic activity. This involves directing funds into areas like social services, health, and education, which injects money directly into the system and influences businesses operating within that economy.
Effects of different types of government spending
- Spending on welfare benefits - Adjustments to benefits have a rapid effect because recipients quickly gain or lose disposable income. For example, higher benefits increase spending power, which can raise demand for goods and services, benefiting firms.
- Spending on infrastructure - Investments in roads, transport, or utilities take longer to impact the economy. These improvements help businesses by speeding up access to raw materials, reducing costs, and making it easier for customers to reach them, potentially boosting demand over time.
The impact of taxation on businesses and consumers
Taxation allows governments to collect revenue from individuals and firms, with changes in rates directly affecting spending and business decisions. Taxes are categorised as direct (on income or profits) or indirect (on spending).
Types of taxes and their effects on individuals
- Income tax - This is a direct tax on personal earnings. Higher rates cut disposable income, leading to reduced consumer spending and lower demand for products. Lower rates increase spending power, encouraging purchases and helping businesses grow profits.
- Indirect taxes - These include value-added tax (VAT) and duties on items like tobacco, alcohol, or pollution. High rates can discourage spending, reducing economic activity, while lower rates or subsidies can motivate consumers to buy more.
Types of taxes and their effects on businesses
- Taxes on profits - Sole traders and partnerships pay income tax on earnings, while limited companies pay corporation tax, both direct taxes. High rates lower after-tax profits, limiting funds for reinvestment or expansion.
- Business rates - This tax is based on property values, which are often higher in southern regions than northern ones, influencing where firms choose to locate to manage costs.
- Overall impact of tax changes - Increasing taxes can slow business growth by raising costs and cutting demand, while reducing them or offering subsidies can encourage expansion and investment.
How tax changes influence luxury and staple goods
Tax adjustments affect demand differently based on the type of product. Luxury items see bigger shifts in demand when incomes change due to taxes, while essential items maintain more steady demand.
Income elasticity of demand and its effects
Income elasticity of demand (YED) measures how the quantity demanded of a good changes in response to a shift in consumer income. It helps explain why some products are more sensitive to economic changes than others.
Formula for income elasticity of demand
Where:
- Percentage change in quantity demanded = ((new quantity - old quantity) / old quantity) × 100
- Percentage change in income = ((new income - old income) / old income) × 100
A positive YED greater than 1 indicates an income-elastic good (demand changes more than income), typical for luxuries. A YED between 0 and 1 shows an income-inelastic good (demand changes less than income), common for necessities.
Worked example - Calculating income elasticity of demand
A consumer's income rises from $30,000 to $36,000, and their demand for luxury holidays increases from 4 to 7 per year. Calculate the YED and interpret what it means.
Step 1: Identify the values
- Old income = $30,000
- New income = $36,000
- Old quantity = 4 holidays
- New quantity = 7 holidays
Step 2: Calculate percentage changes
Percentage change in income = (($36,000 - $30,000) / $30,000) × 100 = 20% Percentage change in quantity demanded = ((7 - 4) / 4) × 100 = 75%
Step 3: Apply the YED formula
Step 4: Interpretation
A YED of 3.75 means demand is income elastic; a 20% income rise leads to a 75% increase in demand, typical for luxury goods like holidays.
The stages of the business cycle and business responses
The business cycle illustrates fluctuations in economic activity over time, moving through phases of growth and decline. Governments use tools like taxation, spending, and monetary policy to aim for steady, sustainable growth.
Stages of the business cycle
- Boom - High gross domestic product (GDP), full production capacity, shortages of goods, rising prices, and increasing wages.
- Recession - Falling incomes, reduced demand, and declining business confidence.
- Slump - Low GDP, factory closures, rising redundancies and unemployment, and increased business failures through insolvency or bankruptcy.
- Recovery - Growing production, higher employment, and increased consumer spending.
Income elasticity affects how cycles impact firms: demand for income-elastic products swings sharply, while income-inelastic products remain more stable.
How businesses respond to business cycle changes
- During booms - Firms may increase prices to boost profits, though this could temper demand. Prolonged booms allow investment in new facilities or product development.
- During recessions - Strategies include making redundancies, maximising use of existing capacity, or shifting to national markets if the downturn is local.
- In national or global downturns - Businesses might target international markets or, in severe long-term cases, relocate abroad.
- In global upswings - Opportunities arise for broad growth, but global recessions harm all firms regardless of location.
Microeconomic and macroeconomic uncertainty
Businesses operate in environments with varying levels of uncertainty, which can stem from specific market factors or broader economic issues. Understanding the difference helps in planning responses.
Differences between microeconomy and macroeconomy
- Microeconomy - Focuses on individual consumers and firms in a particular market.
- Macroeconomy - Covers the whole economy, including all businesses and consumers.
Sources of uncertainty in business environments
- Microeconomic uncertainty - Includes new competitors entering the market or shortages of raw materials, affecting specific sectors.
- Macroeconomic uncertainty - Involves wider issues like changes in government, alterations to international trade deals, or new legislation impacting the entire economy.
Businesses address these risks through economic forecasting, which predicts future trends, and scenario planning, which prepares for different possible outcomes.
