How can the saying "Knowledge, if accompanied by awe, is with you; otherwise, it is against you" be applied to the study of economics, which is based on man-made laws and economic problems?

Knowledge, if intended for the sake of Allah, is good for its possessor. But if it is intended for an evil purpose, it becomes a detriment to him, as stated in the noble Hadith about the first people with whom Hellfire will be ignited. The wisdom, "If knowledge is accompanied by awe of God, it is with you; otherwise, it is against you," applies to the study of economics and other fields. Islam encourages strength and striving for what is beneficial, and economics is one of the sources of strength. Allah Almighty says: (It is He who made the earth subservient to you, so walk in its regions and eat from His provision) and (And prepare for them whatever you are able of power). The Prophet, peace and blessings be upon him, said: "A strong believer is better and more beloved to Allah than a weak believer."

Studying man-made laws is permissible for a legitimate purpose, such as knowing the superiority of Islamic law over them, or benefiting from them in ways that do not contradict Islamic law, provided that it does not distract from individual obligations and duties, and with the dislike of judging by them. The evidence for this is Hudhayfah's question, may Allah be pleased with him, about evil. However, if the purpose of studying economics or man-made laws is to engage in work that contradicts Islamic law, or to teach them to those who will act upon them, then this is forbidden and will be a detriment to its possessor.
