-
- Sustained increase in the general price level of goods and services over time
- Causes
- Demand-pull inflation occurs when grows faster than (increased consumer spending, government spending, or exports)
- Cost-push inflation happens when increased production costs (raw materials, wages) lead to higher prices (oil price shocks, labor union negotiations)
- Measurement
- Consumer Price Index (CPI)
- Tracks changes in prices of a fixed basket of goods and services (food, housing, transportation)
- Calculated by:
- Producer Price Index ()
- Measures average change in selling prices received by domestic producers for their output (manufacturing, mining, agriculture)
-
- Measures changes in prices of all goods and services produced in an economy
- Calculated by:
- Consumer Price Index (CPI)
- Historical impact
- Erodes purchasing power of money, reducing the value of savings and fixed incomes (pensions)
- Redistributes wealth from creditors to debtors as the real value of debt decreases over time
- May lead to economic instability and uncertainty, discouraging investment and long-term planning ( in Weimar Germany, Zimbabwe)
Unemployment: rates and implications
- Unemployment rate
- Percentage of the labor force that is jobless, actively seeking employment, and willing to work
- Calculation:
- Labor force is the sum of employed and unemployed persons
- Types of unemployment
- is short-term unemployment due to job transitions (recent graduates, workers changing jobs)
- occurs when there is a mismatch between skills of workers and job requirements (automation, outsourcing)
- happens due to economic downturns or recessions (decreased consumer demand, business closures)
- Economic implications
- High unemployment
- Reduced consumer spending and economic growth as households have less disposable income
- Increased government spending on social welfare programs (unemployment benefits, food stamps)
- Potential social and political instability due to financial hardship and inequality
- Low unemployment
- Potential inflationary pressures due to increased consumer demand and competition for workers
- Possible labor shortages and upward pressure on wages as businesses struggle to find qualified employees
- High unemployment
GDP as economic indicator
-
- Total value of all final goods and services produced within a country's borders in a given period (quarterly, annually)
- Calculation methods
- Expenditure approach:
- C: Consumer spending on goods and services
- I: Investment spending by businesses on capital goods
- G: Government spending on public goods and services
- X: Exports of goods and services
- M: Imports of goods and services
- Income approach:
- Expenditure approach:
- Real vs. Nominal GDP
- Real GDP is adjusted for inflation and reflects actual growth in production
- Nominal GDP is measured at current prices and not adjusted for inflation
- Limitations as an economic indicator
- Does not account for income distribution or quality of life (poverty, inequality)
- Excludes non-market transactions (unpaid work, black market activities)
- May not capture environmental costs or sustainability (pollution, resource depletion)
- Economic implications
- Growth in real GDP indicates economic expansion and increased standard of living
- Consistent decline in real GDP signals recession and potential job losses
- GDP per capita is often used to compare living standards across countries (developed vs. developing nations)
Economic Cycles and Policy Responses
-
- Fluctuations in economic activity over time, consisting of expansion, peak, contraction, and trough phases
- Aggregate demand and supply
- Aggregate demand represents total spending on goods and services in an economy
- Aggregate supply is the total production of goods and services by all firms in an economy
-
- Government's use of taxation and spending to influence economic conditions
- Can be used to stimulate growth during recessions or control inflation during expansions
-
- Central bank's management of money supply and interest rates to achieve economic objectives
- Tools include open market operations, reserve requirements, and discount rates
-
- The value of one currency in terms of another, affecting international trade and capital flows
