Economic Growth Notes

Real GDP per capita is calculated by dividing the real GDP by the total population. It represents the average GDP per person.
A higher real GDP per capita generally correlates with a better-educated and healthier population.
Real GDP per capita does not measure the quality of life, as it doesn't reflect income distribution.
Key Question: For significant economic growth, a nation's real GDP must increase at a faster rate than its population.

Economic growth is defined as an increase in real GDP per capita over time.
It is graphically represented by outward shifts of the Production Possibilities Curve (PPC) and the Long-Run Aggregate Supply (LRAS) curve.
Economic growth is primarily driven by increases in productivity.

Four main factors determine economic growth:
- Natural Resources
- Human Resources
- Capital Resources
- Technology and Innovation

Access to natural resources such as land, water, forests, oil, and mineral resources is a factor in economic growth.
However, it is not the sole determinant. For example, Japan has limited natural resources but has experienced rapid economic growth.
In contrast, India has the fourth-largest coal reserves globally but has developed more slowly.

The labor force, measured through labor input, is a key factor in economic growth.
The level of human capital, including the skills and knowledge possessed by the labor force, is considered the single most important component in economic growth.

Increased and improved capital goods lead to higher output. More and better-designed machines in factories increase production capacity.
Economic growth occurs when more capital is available per worker.
An increase in the capital-to-labor ratio is known as capital deepening, where workers are equipped with more and better tools.

Technology and innovation are crucial for economic growth.
They promote the efficient use of resources, leading to increased output.
Innovations that reduce the time needed to complete tasks can also boost economic growth.

Productivity is the ratio of the amount of output produced to the amount of input, often measured as "output per worker."

Quality of Labor: A better-educated and healthier workforce tends to be more productive.
Technological Innovation: New machines and technologies enable countries to produce more output from the same amount of inputs.
Energy Costs: Gas, electricity, and other fuels power the technologies that increase productivity. Rising energy costs can make these tools more expensive to use, leading to a decline in productivity.
Financial Markets: Efficient financial markets facilitate the flow of funds, allowing them to be allocated to their best uses, thereby increasing productivity. The absence of such institutions can reduce productivity.

The aggregate production function demonstrates that productivity (or output per capita) is positively related to the quantities of physical capital per worker and human capital per worker, as well as changes in technology.
The relationship can be represented as:

$Real \ GDP \ per \ worker = Productivity$
