Study Notes
Introduction to Macroeconomics
- Macroeconomics studies how entire economies function
- It analyzes broad economic factors and their interactions
- The course explores key macroeconomic concepts, measures, and policies that shape national and global economies
Learning Outcomes
- Key Concepts: Understand core macroeconomic concepts like GDP, inflation, and unemployment
- Economic Measures: Interpret and analyze economic indicators such as GDP growth and CPI
- Economic Policy: Gain insights into fiscal and monetary policy roles
- Global Context: Explore macroeconomic factors' relationship to international trade
Macroeconomics
- Imagine the economy like a giant engine
- Macroeconomists analyze the overall performance, like studying the engine's performance
- GDP (Gross Domestic Product) indicates how much the economy is producing
- Inflation shows if prices are rising too quickly, like overheating
- Unemployment rates show if the engine is stalling
Microeconomics
- Microeconomics focuses on individual interactions happening within a market (a bustling farmer's market)
- It examines how individual farmers decide how many apples to grow and their price
- It looks at how bakers decide on quantities and how prices of ingredients impact their decisions
- Consumers (shopper) make choices impacted by prices, preferences, and other factors
Microeconomics vs Macroeconomics
- Microeconomics examines consumers and businesses' decisions relating to limited resources in specific markets
- This analysis includes interactions, reaction to changes in supply, demand, and prices
- Macroeconomics studies the economy's overall performance, using broad indicators like GDP, inflation, and unemployment
- It helps understand how the economy functions
Key Macroeconomic Issues
- Economic Growth: Measures increase in economy's productive capacity. Crucial for raising living standards
- Inflation: General rise in price levels that can erode purchasing power
- Unemployment: Portion of the labor force unable to find work. High rates indicate economic inefficiency
Gross Domestic Product (GDP)
- Definition: Total value of all final goods and services produced within a country's borders in a year
- Importance: Primary indicator of a country's economic health and growth rate, used to compare economies
- Calculation: Sum of consumer spending, business investment, government spending, and net exports
- Rate of Change: Percentage change in GDP year-on-year indicates the level of economic growth
UK GDP Measure
- Q2 2021 UK GDP reached £520.8 billion, reflecting economic recovery from pandemic disruptions
- GDP growth fluctuated in preceding years due to Brexit uncertainty and global economic shifts
- Economists forecast moderate growth, contingent on post-Brexit trade agreements and global conditions
GDP Growth Rate Comparison
- Specific countries' GDP growth rates are presented for 2019, 2020, and 2021
Inflation Overview
- Definition: Sustained increase in the general price level of goods and services in an economy
- Measurement: Typically measured by changes in the Consumer Price Index (CPI) or GDP deflator
- Impact: Inflation affects purchasing power, savings, investment decisions, and overall economic stability
Consumer Price Index (CPI)
- Definition: Measures average change in prices paid by urban consumers for a market basket of goods
- Calculation: Based on surveys of consumer spending habits and price data from retailers
- Inflation rate: Rate of change of CPI
- Usage: Used to adjust wages, pensions, and government benefits for cost-of-living changes
UK Inflation Rate
- September 2021: UK inflation rate reached 3.1%, exceeding Bank of England's 2% target
- Causes: Supply chain disruptions, energy price increases, pent-up consumer demand
- Implications: Higher inflation may lead to interest rate hikes and reduced consumer purchasing power
Unemployment Concepts
- Definition: Percentage of labor force that is jobless, actively seeking work, and available to work
- Types: Frictional, structural, and cyclical unemployment
- Measurement: Typically calculated through labor force surveys and unemployment benefit claims data
UK Unemployment Trends
- June-August 2018 unemployment rate was 5.6%
- June-August 2021 unemployment rate dropped to 4.6% despite pandemic disruptions
International Trade & Finance Basics
- Exports: Goods and services sold to foreign buyers, contributing to domestic economic growth
- Imports: Goods and services bought from foreign sellers. May increase consumer choice but compete with domestic production
- Trade Balance: Difference between exports and imports. A surplus exists when exports exceed imports, and a deficit, when reversed
Balance of Payments
- Definition: Record of all transactions between a country and the rest of the world
- Components: Current account, capital account, and financial account, each tracking different types of transactions
- Importance: Reflects a country's economic health, international competitiveness, and currency demand
Current Account
- Components: Records trade in goods and services, income flows, and unilateral transfers
- Status: Current account deficit (imports exceed exports), or current account surplus (exports exceed imports)
- Calculation: Formula for calculating current account
- Significance: Large deficits often indicate economic imbalances and potential currency risks
UK Current Account Balance
- 2000-2008: Relatively stable current account deficit
- 2009-2011: Deficit widened post-financial crisis
- 2012-2017: Deficit continued to grow
Interest Rates Overview
- Definition: Cost of borrowing money, expresssed as a percentage
- Types: Nominal, real, and effective
- Importance: Influences saving, borrowing, investment decisions and overall economic activity
Central Banks and Monetary Policy
- Bank of England (UK): Sets base rate to influence broader economy, aiming for a 2% inflation target
- Federal Reserve (US): Uses federal funds rate to manage inflation and employment
- European Central Bank (Eurozone): Sets key interest rates for euro area, focusing on price stability
UK Interest Rate Trends
- 1979: Rates hit a peak of 17% due to inflation
- 1971-2021: Average rate of 7.24%
- 2020: COVID-19 impact resulted in rates cut to 0.10%
- 2024: Post-COVID recovery saw rates increase to 4%
Government Budget Basics
- Government Income: Primarily from taxes
- Government Expenditure: Public services (healthcare, education) and infrastructure, including transfer payments
- The Treasury: Manages national finances by allocating resources
UK Public Sector Borrowing
- Pre-2008: Relatively stable borrowing
- 2008-2010: Sharp increase due to the financial crisis
- 2010-2020: Gradual reduction through austerity measures
The Circular Flow Model
- Households provide factor services to firms and spend on goods/services received from firms
- Firms produce goods and services, paying factor incomes and receiving revenue from sales, thus completing the cycle
Injections and Withdrawals
- Injections: Investment, Government Spending, Exports
- Withdrawals: Savings, Taxes, Imports
Types of Economic Spending
- Consumption (C): Household spending on goods and services (largest component)
- Investment (I): Business spending on capital goods, equipment, structures, and inventories
- Government Spending (G): Public sector spending on goods and services, including consumption and investment
International Trade Components
- Exports (X): Goods and services sold to foreign buyers
- Imports (M): Goods and services bought from foreign buyers
- Net Exports (X-M): Difference between exports and imports. Can be positive (surplus) or negative (deficit)
Aggregate Demand Formula
- Components: AD=C+I+G+(X-M) (consumption + investment + government spending + net exports)
- Significance: Represents total planned expenditure in an economy
- Policy Implications: Changes in components can be targeted by fiscal and monetary policies
Aggregate Supply
- Definition: Total quantity of goods and services that firms are willing to produce at various price levels
- Short-run AS (Upward sloping): Reflects changing production costs as output changes
- Long-run AS (Vertical): Represents potential GDP when resources are fully employed
Macroeconomic Equilibrium
- Definition: Point where aggregate demand equals aggregate supply
- Short-run Equilibrium: Intersection of aggregate demand and short-run aggregate supply
- Long-run Equilibrium: Economy operates at potential GDP
Fiscal Policy
- Definition: Use of government spending and taxation to influence the economy
- Expansionary Policy: Increases government spending or reduces taxes to stimulate economic growth
