Which scenario could shift the production possibilities curve outward?

The scenario that would shift the production possibilities curve outward is technological advancements. When a society experiences technological improvements, it generally leads to more efficient production processes, enhanced productivity, and the ability to produce more goods and services with the same amount of resources. This increase in efficiency allows the economy to maximize its output potential, effectively expanding the production capabilities represented by the production possibilities curve.

In contrast, increased consumer demand typically influences the allocation of resources rather than the total production capacity. Higher taxes on production and increased regulation can lead to a reduction in incentives for production, potentially restricting output and shifting the curve inward or limiting the economy's growth potential. Thus, while these factors can impact the short-term operations of an economy, technological advancements are the key driver for long-term growth and the outward shift of the production possibilities curve.
