Final answer:
Dr. Louise Atwater likely belongs to the Keynesian school of thought, which holds that market imperfections can extend the short-run period, often necessitating government intervention to aid in economic adjustment.
Step-by-step explanation:
Dr. Louise Atwater, who believes that market imperfections are large and may prolong the short run, is most likely aligned with the Keynesian school of thought. Keynesians emphasize the effects of market imperfections and the role of government in smoothing out economic cycles.
They argue that in the presence of such imperfections, prices and wages adjust slowly, which can extend the short-run effects of economic disturbances and may require government intervention to bring the economy back to its potential GDP.
Contrastingly, economists of the neoclassical perspective would expect markets to self-correct more quickly without the need for significant government intervention, as they focus on long-term outcomes where markets are adjusted and display productive and allocative efficiency, reflecting the ability and willingness to pay among consumers in a market.
