Study Notes
Economic Growth
- One of society's main goals is to improve living standards and well-being, which requires increasing available resources. Economic growth, expanding resources, is a key element in this process.
Defining Economic Growth
- Potential growth is an increase in an economy's productive capacity. This is visually represented by a shift in the Production Possibility Frontier (PPF), enabling the production of more goods/services.
- Actual growth, measured by the rate of change in real GDP, may reflect a move towards this potential.
- The AD/AS model can illustrate growth as a shift in the LRAS (long-run aggregate supply) curve outwards. This shift increases full employment output.
- Actual GDP is observable, while potential GDP is the level of output if all resources are used efficiently.
The Output Gap
- The output gap is the difference between actual real GDP and its maximum possible level (potential GDP).
- A negative output gap below full employment means unused resources (unemployment, idle capital).
- A positive output gap shows actual GDP exceeding capacity, often a short-term response to increased demand. Measuring the output gap is challenging as identifying the exact point of full capacity is difficult.
Sources of Economic Growth
- Factors of production (capital, labor, enterprise, land) are crucial.
- An increase in production factors or their productivity elevates capacity output.
- Productivity is a measure of a factor's efficiency (labor productivity = output/worker, etc.).
- Total Factor Productivity (TFP) is the average productivity of all factors.
- Increased productivity boosts aggregate supply and potential output.
Capital
- Capital is essential for production increases.
- Investment (in capital goods) is crucial for accumulating and expanding capital.
- Gross fixed capital formation (net additions to capital, and depreciation) is a key measure of investment.
- Technological advancements (and new forms of capital) increase capital's contribution to potential output.
Labour
- Skilled labor is needed to operate new technologies and capital.
- Labor force size is limited by factors like international migration.
- Labor productivity gains through training and education are key.
Growth and International Trade
- International trade can boost economic growth in smaller countries by enabling specialization and economies of scale (producing more efficiently).
- Expanding export markets can lead to export-led growth, as shown in several East Asian economies.
- Access to larger markets and foreign exchange are essential for many developing countries.
Growth and Aggregate Demand
- An increase in aggregate demand leads to higher real output, especially when initial output is below full potential.
- This is considered actual growth, not a change in capacity.
- Investment-driven increases in AD can lead to increases in productive capacity.
