Final answer:
An economist should consult with other economists, apply fundamental economic principles, adjust existing models, or develop new ones when faced with an unprecedented problem without a specific model for analysis.
Step-by-step explanation:
When an economist encounters a novel problem without a pre-existing model for analysis, a pragmatic approach is necessary. Drawing inspiration from the hint provided, a carpenter facing an unfamiliar situation adapts by leveraging their foundational skills, collaborating with other craftsmen, and sometimes inventing new techniques or tools. Similarly, an economist should seek guidance from other economists, apply fundamental economic principles, and adjust established models or develop new ones to suit the unique aspects of the issue.
If none of the existing economic models seem to fit the problem at hand, the economist could consult with other economists who might have encountered similar issues or have complementary knowledge. This collaboration could lead to pooling different insights, fostering creative thinking, and eventually overcoming the lack of a specific model. It's important to ensure that a multidisciplinary perspective is considered, as this can provide a more comprehensive approach to the issue. Ultimately, flexibility, collaboration, and innovation are key when dealing with uncharted economic issues, much like what a skilled carpenter would do when faced with a new challenge.
