Aggregate Supply Explained: What It Is, How It Works
Total production, or aggregate supply, is the total amount of products and services produced in an economy at a certain price in a given period. The aggregate supply curve shows how price levels affect firm production. Usually, aggregate supply and price levels are positive.
Explaining Aggregate Supply
Rising prices usually mean enterprises should increase production to fulfill aggregate demand. Constant supply and rising demand cause consumers to compete for goods and pay higher prices. This drives enterprises to produce more to sell. Price normalization and output stay high due to supply increase.
Aggregate supply changes
Many factors affect aggregate supply, including labor size and quality, technology advances, salary increases, production cost increases, producer taxes and subsidies, and inflation. Some of these factors increase aggregate supply, while others decrease it. Outsourcing or automation can boost labor efficiency, lowering labor cost per supply unit and increasing supply production. In contrast, salary increases raise production costs and lower aggregate supply.1
Short- and long-term aggregate supply
In the near run, aggregate supply increases production inputs to meet greater demand and prices. In the short term, capital is fixed. Therefore, a corporation cannot build a factory or adopt new technologies to boost production. Instead, the corporation boosts supply by boosting worker hours or technology utilization.
In the long run, aggregate supply is driven primarily by productivity and efficiency gains, not price. Increases in labor skills, education, technology, and capital are examples. Keynesian economics holds that long-run aggregate supply is price elastic up to a point. Supply becomes price-insensitive after this stage.2
Example of Aggregate Supply
While producing 100,000 widgets every quarter for $1 million, XYZ Corporation’s 10% important component increases in price due to a lack of resources or other external circumstances. If it spends $1 million on production, XYZ Corporation could only make 90,909 widgets. These cuts would lower aggregate supply. Lower aggregate supply may cause demand to surpass output. This, together with rising production costs, may raise prices.
Conclusion
- Total products produced at a single price point for a period constitute aggregate supply.
- Demand fluctuations largely affect aggregate supply in the short term.
- Long-term aggregate supply variations are most affected by new technologies or industry developments.
