Assume that the U.S. PPF measures oil and gas production on the ​x-axis and production of other goods and services on the ​y-axi
iris [78.8K]

Answer:

The U.S. PPF rotates​ outward (abticlockwisely), increasing the ​x-axis intercept with no change in the y-axis intercept

Step-by-step explanation:

Fracking is a method of improving production capabilities on oil and gas production. Although, it usually leads to environmental pollution later, it does bring in higher yields of oil and gas.

If the oil and gas production on the x-axis increases without a simultaneous, almost equal increase in production of other goods and services (on the y-axis), the data points for the x-axis shift more to the right and the PPF rotates more anti-clockwisely outward, thereby increasing the intercept on the now improved x-axis and not too much change on the intercept of the y-axis.
