Once you've written the main paragraphs of your economic essay you can consider the main part of the writing done. However, this does not mean you can relax and expect your essay to come out with a good conclusion. A solid conclusion is crucial for any paper, even an economics essay example. Your conclusion is the section of your essay that most contribute to the overall impression your reader has of your writing. A weak conclusion can also leave your reader with a negative impression.
A conclusion can be thought of as the final version of your essay. When your reader has finished reading your paper, this is the conclusion. Reiterating your main argument from the introduction is a fine way to end your essay.
It's a mistake to think that once you've written your essay, you can submit it. It is important to remember that this is a draft and needs some editing before you submit it.
