If the user asks question that shows no evidence of prior search/research effort you might use the following generic response (special thanks to Mark C. Wallace - mod from History.SE for allowing us to repurpose their generic answer).
Welcome to Economics:SE. Thank you for your question; please consider revising it to be more in line with our community expectations. Like many other stacks,
[we expect questions to provide evidence of prior research](https://economics.stackexchange.com/help/how-to-ask).
That helps us to understand the question, and avoids our repeating work you've already done. Our[help center](https://economics.stackexchange.com/help),
and[other stacks](https://interpersonal.meta.stackexchange.com/questions/3224/how-do-i-write-a-good-question)
provide additional resources to assist with revisions.
Note to future mods: You can also consider using automatic post notice in appropriate situations.
