1.4 Macroeconomics: The Big Picture

Macroeconomic indicators are crucial tools for assessing a nation's economic health. These measures, including GDP growth, employment rates, and price stability, provide insights into the overall performance of an economy. Understanding these indicators helps businesses and policymakers make informed decisions.

Business cycles, fiscal policies, and monetary policies play significant roles in shaping economic conditions. By examining unemployment types, inflation causes, and additional indicators like GNP and trade balance, we gain a comprehensive view of economic dynamics. This knowledge is essential for navigating the complex landscape of modern economies.

1 of 3

• Economic growth
  • Measured by percentage change in real GDP
  • Real GDP adjusts for inflation represents total value of all goods and services produced within a country's borders (United States)
  • Positive economic growth indicates expanding economy leads to higher living standards and increased economic health
  • Economic growth rate measures the speed at which the economy is expanding or contracting
• Employment rates
  • High employment rates suggest strong labor market and thriving economy
  • Low unemployment rates indicate more people working, earning income, and contributing to economic growth
  • High unemployment rates signal weak economy can lead to reduced consumer spending and slower economic growth
• Price stability
  • Occurs when general price level in an economy remains relatively constant over time
  • Low and stable inflation rates associated with price stability (2% annual inflation target)
  • Price stability fosters economic health by providing predictable environment for consumers and businesses encourages investment and long-term planning

Business Cycles and Economic Policies

• Business cycles
  • Fluctuations in economic activity over time, including periods of expansion and contraction
  • Influenced by various factors such as consumer spending, investment, and government policies
• Fiscal policy
  • Government's use of taxation and spending to influence the economy
  • Can be used to stimulate growth during recessions or cool down an overheating economy
• Monetary policy
  • Actions taken by the central bank (Federal Reserve System in the US) to manage money supply and interest rates
  • Used to promote price stability, full employment, and sustainable economic growth

Unemployment and Inflation

Types and impacts of unemployment

• Frictional unemployment
  • Short-term unemployment occurs when people are transitioning between jobs
  • Considered normal part of job search process has minimal impact on economy
• Structural unemployment
  • Caused by mismatch between skills of unemployed and requirements of available jobs
  • Can result from technological advancements or shifts in economy (decline of manufacturing industry)
  • May have more significant and longer-lasting impact on economy compared to frictional unemployment
• Cyclical unemployment
  • Occurs during economic downturns or recessions when there is decrease in demand for goods and services
  • Businesses lay off workers to cut costs leading to higher unemployment rates
  • Can have severe impact on economy as reduced consumer spending further exacerbates economic downturn (2008 financial crisis)
• Seasonal unemployment
  • Results from predictable changes in labor demand due to seasonal patterns (holiday hiring, agricultural work)
  • Generally has limited impact on overall economy as it is anticipated and temporary

Demand-pull vs cost-push inflation

• Demand-pull inflation
  • Occurs when aggregate demand for goods and services exceeds aggregate supply
  • Caused by factors such as increased consumer spending, government spending, or exports
  • Results in higher prices as businesses raise prices to meet increased demand (housing market boom)
• Cost-push inflation
  • Occurs when cost of production increases leading to higher prices for goods and services
  • Caused by factors such as rising raw material costs, higher wages, or increased taxes
  • Businesses pass increased costs on to consumers in form of higher prices (oil price shocks)
• Measuring inflation
  1. Consumer Price Index (CPI)
     • Measures average change in prices paid by urban consumers for basket of goods and services
     • Calculated monthly by Bureau of Labor Statistics
  2. Producer Price Index (PPI)
     • Measures average change in prices received by domestic producers for their output
     • Focuses on cost of production can provide insight into future consumer price changes
  3. GDP deflator
     • Measures change in prices of all goods and services produced in an economy
     • Calculated by dividing nominal GDP by real GDP and multiplying by 100
     • $GDP deflator = \frac{Nominal GDP}{Real GDP} \times 100$

Additional Economic Indicators

• Gross National Product (GNP)
  • Measures the total value of goods and services produced by a country's residents, regardless of location
  • Differs from GDP by including income from foreign investments and excluding domestic production by foreign companies
• Balance of trade
  • Difference between a country's exports and imports
  • A positive balance (trade surplus) occurs when exports exceed imports, while a negative balance (trade deficit) occurs when imports exceed exports
