The 2023 Harvard International Economics Essay Contest is sponsored by the Harvard Undergraduate Economics Association (HUEA) in conjunction with the Harvard College Economics Review (HCER). This essay competition is open to high school students of any year and is a fantastic opportunity to demonstrate an accomplished level of writing and understanding of economic theory. Through the contest, student competitors hone their academic and professional skills and exhibit their knowledge to future employers and academic programs. Competitors must construct a convincing argument using economic theory and real-world examples. Winning essays will be published in the Harvard Economics Review and will be available for the greater Harvard community to read. Essays should focus on argumentation supported with facts and references, although data-based support is also welcome.
