As an economics major, writing may not be your strongest suit. And that's okay; you just need to be willing to look for resources that can help you with your writing. If you are looking for help for your economics research paper, there are a number of places that you can find the help that you need. Here are a few of the places that you should consider if you need help with your writing.
Your college or university's writing center. Your college or university likely has a writing center that you can go to and get help with writing your paper. Whether you're struggling with brainstorming or need someone to edit your paper, there's someone there that can give you the assistance that you need in writing your economics research paper.
An online paper writing or editing service. There are a number of online services that specialize in writing and/or editing papers. These services can help you with the same things that your writing center can, but they usually come with a cost. They are inexpensive, however, and if you pick a company that has native English speakers on staff, the work you receive will be worth the money you put into it.
A freelancer. Much like online paper writing or editing services, a freelancer can provide you with writing and editing services as well. The advantage of hiring a freelancer is that you get to handpick the person who is doing the work for you. They may be a bit more expensive than the services listed above, however.
Your professor. Your professor, obviously, isn't going to write your paper for you, but they can help you with the writing process. They can help you narrow down your topic, outline your work, and even determine if your thesis is acceptable for the research paper that you are doing. The advantage of going to your professor is that they have a Master's degree or Doctorate in economics, so they're going to know a lot more than anyone else that you may approach for help.
Colleagues and/or friends. If you need writing help and you have friends or colleagues that offer their assistance, utilize them. You don't have to pay them, and they know you well enough that they can get into your head and help you figure out what you want to talk about in your paper. Just make sure you take them out to lunch or something else as a thank you for the work they put into helping you, okay?
