The measurement of macroeconomic performance

• What are the main objectives of government economic policy?


  • Economic Growth: Increase in the production of goods and services, measured by real GDP.
  • Price Stability: Maintaining low and stable inflation, usually targeting around 2%.
  • Minimising Unemployment: Reducing the number of people unable to find work.
  • Stable Balance of Payments on Current Account: A balanced trade of goods and services with other countries, preventing persistent deficits or surpluses.
• Why is economic growth important for a government?

  • Higher Standards of Living: More goods and services are produced, leading to better living conditions.
  • Job Creation: Economic expansion creates more employment opportunities.
  • Government Revenue: Higher GDP leads to more tax revenue without raising tax rates.
  • Sustained Long-term Benefits: Boosts productivity, technology, and wealth.
• Why is price stability important for an economy?


  • Avoiding Inflation: High inflation reduces purchasing power and creates uncertainty.
  • Preventing Deflation: Deflation can lead to reduced consumer spending and economic stagnation.
  • Economic Certainty: Helps businesses and consumers plan for the future, fostering confidence.
• Why is minimising unemployment important for economic policy?

  • Economic Efficiency: Unemployment indicates underused resources, reducing overall productivity.
  • Social Costs: High unemployment leads to poverty, inequality, and social unrest.
  • Government Expenditure: Unemployment increases welfare claims, straining government finances.
• What is the importance of maintaining a stable balance of payments on the current account?


  • Trade Surplus: A surplus suggests the country is exporting more than importing, which strengthens the economy.
  • Trade Deficit: A deficit can lead to borrowing and currency depreciation.
  • Foreign Reserves: A surplus helps accumulate reserves, reducing reliance on foreign loans.
• Conflicts Between Economic Policy Objectives


  • Economic Growth vs. Price Stability: Growth can lead to inflationary pressures if demand outstrips supply.
  • Unemployment vs. Price Stability: Policies to reduce unemployment (e.g., increasing demand) can cause inflation.
  • Economic Growth vs. Balance of Payments: Increased demand during growth can lead to higher imports, worsening the current account balance.
• What other economic objectives might governments pursue?

  1. Balancing the Budget: Ensuring government spending equals revenue to avoid excessive debt.
  2. Equitable Distribution of Income: Reducing income inequality through taxation, welfare, and public services.
• What are the commonly used macroeconomic indicators to measure an economy’s performance?


  1. Real GDP: Total value of goods and services produced, adjusted for inflation.
  2. Real GDP per Capita: GDP divided by population, used to compare living standards.
  3. Consumer Price Index (CPI) & Retail Price Index (RPI): Indices that measure changes in the price level of a fixed basket of goods and services.
• What are 3 more commonly used macroeconomic indicators to measure an economy’s performance?


  1. Unemployment Rate: Percentage of the labor force that is jobless but actively seeking work.
  2. Productivity: Output per hour worked or per worker.
  3. Balance of Payments on Current Account: Measures trade and financial transactions with other countries.
• What does real GDP represent, and why is it important?

  • Definition: The total value of all goods and services produced, adjusted for inflation.
  • Why It Matters: It shows whether an economy is growing or contracting and helps policymakers set appropriate economic strategies.
• Why is real GDP per capita useful for comparing living standards?


  • Definition: Real GDP divided by the total population, giving an average measure of income or living standard.
  • Why It Matters: Helps compare standards of living across countries and track changes in living conditions over time.
• What is the difference between the Consumer Price Index (CPI) and Retail Price Index (RPI)?


  • CPI: Measures price changes for a selected basket of goods and services, excluding housing costs like rent and mortgage interest.
  • RPI: Includes housing costs, making it a broader measure of inflation.
  • Why It Matters: Both are used to measure inflation, which is vital for economic policy decisions.
• What does the unemployment rate indicate about an economy?


  • Definition: The percentage of the labor force that is jobless but actively seeking work.
  • Why It Matters: High unemployment signals inefficiency in the economy and can lead to social and economic problems like poverty and inequality.
• What is productivity, and why is it important?


  • Definition: Measures the efficiency with which goods and services are produced, often expressed as output per worker or per hour worked.
  • Why It Matters: Higher productivity leads to higher living standards, lower costs, and more competitive industries, driving economic growth.
• Why is the balance of payments on the current account important?


  • Definition: A record of a country’s trade in goods, services, income, and transfers with the rest of the world.
  • Why It Matters: A surplus indicates that the country is exporting more than it imports, while a deficit may require borrowing or lead to currency devaluation.
• How are index numbers used and calculated?


  • Base Year: Set to 100, and subsequent years are compared against it.
  • Weights: Reflect the importance of each component in the index (e.g., food vs. entertainment in CPI).
  • Interpretation: A value of 110 means a 10% increase compared to the base year.
• How are index numbers used in economics?


  • Measuring Inflation: CPI and RPI are used to track changes in the price level.
  • Comparing Economic Variables: Can measure changes in GDP, wages, or national income, providing a clear view of economic trends.
• How can national income data be used to assess living standards?


  • Use: National income measures total economic output and average income.
  • Limitations: Does not reflect income distribution, non-market activities, or environmental sustainability.
• How is national income data used for international comparisons?


  • Purchasing Power Parity (PPP): Adjusts exchange rates to reflect price level differences between countries, giving a more accurate measure of living standards.
  • Limitations: Differences in data collection methods and environmental costs may distort comparisons.
• What are the limitations of using national income data for comparing living standards?


  • Income Inequality: National income doesn’t show how income is distributed within a country.
  • Non-Market Activities: Excludes unpaid work or informal sectors, which are important for assessing actual welfare.
  • Environmental Costs: National income doesn’t account for environmental degradation that could undermine long-term well-being.
• How do economic policy objectives sometimes conflict with one another?


  • Growth vs. Inflation: Stimulating growth (e.g., through fiscal policies) can lead to inflationary pressures if demand outpaces supply.
  • Unemployment vs. Inflation: Efforts to reduce unemployment (e.g., by increasing government spending) can cause inflation, especially if the economy is at or near full capacity.
  • Growth vs. Trade Balance: Economic growth increases demand for goods and services, often leading to increased imports, which can worsen the current account balance and create a trade deficit.
• How do government economic objectives change over time?


  • Short-term Focus: In times of recession or economic slowdown, governments may prioritize reducing unemployment and stimulating growth, sometimes at the expense of controlling inflation or maintaining a balanced budget.
  • Long-term Focus: Over the longer term, governments often emphasize achieving sustainable growth, price stability, and a stable current account balance to ensure a strong and resilient economy.
• Why is balancing the government budget a key objective?


  • Avoiding Excessive Debt: A balanced budget prevents the accumulation of unsustainable government debt, reducing the risk of a debt crisis.
  • Sustainable Public Services: Without high deficits, governments are better positioned to fund essential public services and investments.
  • Fiscal Policy Flexibility: A balanced budget provides flexibility to respond to future economic challenges without relying heavily on borrowing.
• Why might a government aim to achieve an equitable distribution of income?


  • Social Cohesion: Reducing income inequality can enhance social stability and cohesion, preventing class divisions and social unrest.
  • Poverty Reduction: An equitable distribution of income helps to lift people out of poverty and ensures that more individuals have access to basic needs like education, healthcare, and housing.
  • Economic Efficiency: Reducing inequality may increase overall economic efficiency by promoting greater investment in human capital (e.g., education, healthcare) and stimulating consumer demand.
• What are the limitations of using real GDP as a measure of economic well-being?

  • Ignores Income Distribution: Real GDP doesn’t account for how income is distributed among the population, meaning it could increase while inequality rises.
  • Excludes Non-Market Activity: Activities like unpaid work (e.g., housework or volunteering) are not counted in real GDP, even though they contribute to well-being.
  • Environmental Degradation: Real GDP might grow despite the depletion of natural resources or environmental harm, which can negatively affect long-term prosperity.
• What is the difference between GDP (Gross Domestic Product) and GNP (Gross National Product)?

  • GDP: Measures the total value of goods and services produced within a country’s borders, regardless of who owns the production assets.
  • GNP: Measures the total value of goods and services produced by the residents of a country, both domestically and abroad, including income earned from abroad and excluding income earned by foreign residents in the domestic economy.
• What are the implications of high and low unemployment rates?


  • High Unemployment: Leads to loss of economic output, higher government spending on welfare, and social problems such as increased crime, poverty, and mental health issues.
  • Low Unemployment: Suggests that labor resources are being fully utilized, contributing to economic growth and higher consumer confidence. However, very low unemployment can also lead to labor shortages, pushing up wages and creating inflationary pressures.
• What are the differences between the CPI and RPI, and how are they used?

  • CPI: Measures price changes for a basket of goods and services but excludes housing costs (e.g., rent, mortgage). It is often used to target inflation.
  • RPI: Includes housing costs such as rent and mortgage payments, making it a broader measure of inflation.
  • Use: Both indices help track inflation and assess changes in the cost of living. Policymakers use these indices to adjust interest rates and set fiscal policies.
• Why is real GDP per capita an important indicator for comparing living standards?

  • Definition: Real GDP per capita divides a country's total real GDP by its population, showing average income or output per person.
  • Importance: It allows for comparisons of economic well-being between countries with different population sizes and provides insight into the average living standards of individuals within the country.
• What are the limitations of using national income data to compare living standards between countries?

  • Differences in Cost of Living: National income data does not account for differences in the cost of living between countries, which can distort comparisons.
  • Non-Market Activities: Unpaid work (e.g., caregiving or volunteering) is not included in national income data, but it contributes significantly to well-being.
  • Environmental Impact: National income figures may increase despite environmental damage, which could negatively affect long-term living standards.
• What is Purchasing Power Parity (PPP) and why is it important for international comparisons of living standards?

  • Definition: PPP is an exchange rate method that adjusts for differences in price levels between countries, providing a more accurate comparison of living standards.
  • Importance: It removes the distortion caused by fluctuating exchange rates and enables better comparisons of income, wages, and costs between countries with different price levels.
• How does national income data fail to account for certain aspects of economic well-being?

  • Non-Market Activities: Activities like unpaid work, informal economies, or volunteer services are excluded, yet they significantly contribute to social welfare.
  • Environmental Costs: The depletion of natural resources or environmental degradation is not reflected in national income, even though it might harm long-term living standards.
• How does national income fail to address environmental sustainability?

  • Limitations: National income might increase despite negative environmental impacts (e.g., pollution, deforestation), which can reduce the quality of life in the future.
  • Example: A country could see a rise in GDP due to industrial output, but if this is achieved through environmentally damaging practices, the long-term costs (e.g., health problems, resource depletion) could outweigh the benefits.
• What are index numbers used for in economics?

  • Measuring Changes in Prices: Index numbers, like the CPI and RPI, track changes in the price level of a fixed basket of goods and services over time.
  • Tracking Other Economic Variables: Index numbers can also be used to measure changes in GDP, wages, and productivity.
  • Comparisons Over Time: They provide a way to compare economic conditions at different points in time or between different regions or countries.
• What are some limitations of using index numbers?

  • Base Year Selection: The choice of base year can affect the interpretation of index numbers, as economic conditions may differ significantly between base years.
  • Changes in Consumer Behavior: Index numbers often assume that consumption patterns stay constant over time, which may not reflect changes in consumer preferences or technological advances.
  • Substitution Bias: Consumers may switch to cheaper alternatives as prices rise, but index numbers often fail to capture these substitutions, leading to an overestimate of inflation.
