How can we measure economic growth?
In economics, growth is commonly modeled as a function of physical capital, human capital, labor force, and technology. Increasing the quantity or quality of the working-age population, the tools that they have to work with, and the recipes that they have available to combine labor, capital, and raw materials will lead to increased economic output. Economic growth, as we said before, is an increase in the production of the quantity and quality of the economic goods and services that a society produces. The total income in a society corresponds to the total sum of goods and services the society produces — everyone’s spending is someone else’s income. This means that the average income corresponds to the level of average production so the average income in a society increases when the production of goods and services increases.

A loaf of bread doesn’t cost $2 but $40, a pair of jeans costs $400, and an old car costs $40,000. If you ask yourself how these price increases would change your daily consumption and your day-to-day life, you can get a sense of what it means to live in a poor country. When a level of real output is below the full capacity level of output (Y5), AD shifts from AD1 to AD2 increasing the real output (Y1 to Y2), but not the price level (P1). When an economy has plenty of spare capacity the aggregate demand can increase without creating inflationary pressures.
