Why do economists spend time thinking about conditions that almost never exist?

Economists analyze rare conditions, like perfect competition or complete information, to better understand how markets function under ideal circumstances. These theoretical models help clarify fundamental principles and provide a benchmark against which real-world scenariOS can be evaluated. By examining these "what-if" situations, economists can identify inefficiencies and design policies that may improve outcomes in more complex, imperfect conditions. Additionally, these models can stimulate critical thinking and innovation in economic theory and practice.
