Final answer:
It is difficult to determine if Sara was behaving rationally when she bought those shoes without more information. Economic rationality assumes that individuals make decisions that maximize their utility or satisfaction, taking into account the costs and benefits.
Step-by-step explanation:
From the economist's perspective, it is difficult to determine if Sara was behaving rationally when she bought those shoes without more information. Economic rationality assumes that individuals make decisions that maximize their utility or satisfaction, taking into account the costs and benefits. It is possible that Sara bought the shoes based on her personal preference, which would align with rational behavior. However, if she did not consider the potential negative consequences of buying the shoes, such as the impact on her budget or financial goals, it could be argued that she did not behave rationally. Ultimately, the answer depends on the specific circumstances and information surrounding her decision.
