Final answer:
New teaching techniques that improve the educational performance of high school seniors can lead to a more skilled workforce, increased productivity, and thus higher full-employment output in the long term.
Step-by-step explanation:
Improving the educational performance of high school seniors with new teaching techniques can lead to an increase in full-employment output. When students acquire better education and skills, they become part of a more qualified workforce, capable of higher productivity. As the education and skill levels of the labor force improve, the economy can leverage these human capital investments to enhance efficiency and output. Higher education levels can also lead to innovation and technological advancements, further increasing productivity and, consequently, the potential for full-employment output.
In the neoclassical view, full-employment is determined by the supply side factors like the production capacity of the economy. In the long run, where wages and prices are flexible, it is the aggregate supply, influenced by factors like the productivity of the workforce, that determines the real GDP's size. Therefore, any improvement in the educational performance that boosts productivity is likely to have a positive impact on full-employment output.
