How is aggregate supply defined?

Aggregate supply is defined as the total supply of goods and services that producers in an economy are willing and able to sell at a given price level over a specific period. This concept is rooted in the relationship between the price levels and the output offered by producers.

When we consider aggregate supply, we recognize that various factors influence the amount of goods and services available in the economy, including production costs, technology, and the availability of resources. At higher price levels, producers are typically incentivized to increase output, as their revenue may rise, covering higher costs. Thus, the definition captures the essence of how much an economy is capable of producing when prices are stable.

The other options are related to economic concepts but do not correctly define aggregate supply. The overall production capacity reflects potential output but does not focus specifically on the relationship with price levels. Total demand refers to the amount of goods and services consumers wish to purchase, which is distinct from supply. Finally, the sum of all taxable income speaks to taxation and income distribution rather than the supply aspect of the economy. Therefore, the definition emphasizing total supply at a given price level accurately characterizes aggregate supply in macroeconomic terms.
