PPF - Outward Shifts: Videos & Practice Problems

In examining the impact of technological advancements and resource changes on societal productivity, it becomes evident that societies tend to become more efficient over time. This is particularly noticeable when comparing current technological capabilities to those from a century ago. The concept of outward shifts in production possibilities can be illustrated through two distinct scenarios, focusing on how advancements in specific industries affect overall production.

In the first scenario, consider a technological breakthrough in a particular industry, such as pizza production. This advancement, represented graphically, results in a shift on one side of the production possibilities frontier (PPF). For instance, if a new oven is developed that allows for faster pizza production, the maximum output of pizzas increases while the production capacity for robots remains unchanged. This can be visualized as a rightward shift in the pizza production axis of the PPF, indicating that more pizzas can be produced without affecting the maximum number of robots that can be created.

As a result of this technological improvement, even if the society chooses to maintain its current level of pizza production, the increased efficiency allows for a reallocation of resources. This means that some resources previously dedicated to pizza can now be redirected towards robot production, leading to an increase in the total number of robots produced. Thus, the advancement in pizza technology not only enhances pizza output but also indirectly boosts robot production by optimizing resource allocation.

This example highlights the dynamic nature of production capabilities within an economy, demonstrating how targeted technological improvements can lead to significant shifts in production potential across different sectors.

In economic terms, a general increase in the availability of resources or technology can lead to enhanced productivity across various industries. This phenomenon can be illustrated through a graphical representation of production possibilities. For instance, consider the improvement in pizza ovens, which specifically boosts pizza production. However, a broader increase in resources—such as a growing population due to immigration or the acquisition of oil from conflict—can elevate productivity across multiple sectors.

When visualizing this concept on a graph, the initial production possibilities curve represents the economy's output capacity. Following a general increase in resources or technology, both axes of the graph shift outward, indicating that production of both goods has increased. This outward shift signifies that the economy can now produce more of both goods simultaneously, reflecting an overall enhancement in productivity.

It is important to note that inward shifts of the production possibilities curve are rare and typically occur only under extreme circumstances, such as a catastrophic event that depletes resources. In most cases, advancements in technology and resource availability lead to outward shifts, demonstrating the economy's growth potential.
