when all factors input are reduced by half, the production possibility curve will shift
Answer Details
When all factors input are reduced by half, the production possibility curve will shift inwards. This means that the maximum amount of goods and services that can be produced with the reduced factors of production will be lower than before. The reason for this is that the production possibility curve represents the trade-off between producing different goods and services with limited resources. When the resources are reduced, the economy is no longer able to produce the same amount of goods and services as before, hence the production possibility curve shifts inwards. This represents a reduction in the potential output of the economy, which can have negative effects on economic growth and development.
