Using a Production Possibility Curve (PPC), analyse the effect of a decrease of some of the resources on an economy.

A decrease in some of the economy's resources, such as labor, capital, land, or raw materials, means the economy has fewer inputs available for production. This directly reduces the overall productive capacity.

When resources decrease, the economy can no longer produce as much as it could before. This is represented by an inward shift of the entire Production Possibility Curve. The curve moves closer to the origin, indicating that the maximum potential output for both goods has diminished.

The inward shift of the PPC signifies a reduction in the economy's potential output and productive capacity. This means the economy can produce fewer goods and services overall, leading to a lower potential Gross Domestic Product (GDP) and a decrease in the overall standard of living if the economy was previously operating efficiently.

The effect of a decrease of some of the resources on an economy, using a Production Possibility Curve (PPC), is an inward shift of the entire PPC. This indicates a reduction in the economy's overall productive capacity and potential output.
