Q: What would be the beneficence of my study?

It’s not clear if you indeed mean ‘beneficence’ or perhaps benefit/significance of the study.

Beneficence is concerned with ethics in research, and involves the researcher keeping the interest of the participant/s in mind. While you seem to wish to study the sales policy of Cemenco (a cement company in Liberia also known as Liberia Cement Corporation), you haven’t mentioned how there could be a potential risk to the participant(s). In any case, in any research, you need to keep the interests – privacy, confidentiality, and welfare – of the participant in mind before undertaking the study. Additionally, you need the consent of the participant before proceeding with the study. You may learn more about ethics and consent through the following resources:

• The need for ethics approval
• Informed consent

Now, in case you meant the benefit or significance of the study, that is the potential importance of your study for the broad area of study or for the target population. If so, you may learn more here: What is meant by the significance of the study?

Note that the first concept is something you discuss in the Methods section and the second is something you discuss in the Introduction section.

Hope that helps. And all the best for your study!
