Is the GRE Math Subject Test Useful for Economics PhD Applications?
These days, economics is not just a qualitative social science; it has become increasingly quantitative, intertwined with statistical and mathematical analyses. This evolution means that students applying for PhD programs in economics must be well-versed in mathematical skills, particularly in calculus, linear algebra, and real analysis. This article aims to explore the usefulness of the GRE Math Subject Test in the context of economics PhD applications.
The Modern Face of Economics
The world of modern economics is not the same as what Adam Smith, Henry George, David Ricardo, and Karl Marx once wrote about. Contemporary economists rely heavily on mathematical and statistical tools to analyze economic theories, conduct empirical research, and predict economic trends. Advanced mathematical concepts such as calculus, linear algebra, and real analysis are fundamental in this era.
About the GRE Math Subject Test
The GRE Math Subject Test is designed to assess the knowledge of mathematics typically covered in undergraduate studies. The test covers the following areas:
50% Calculus 25% Algebra (including linear algebra, abstract algebra, and number theory) 25% Other topics (including discrete math, combinatorics, probability, and other advanced topics)What the GRE Math Subject Test Covers
While calculus and algebra are indeed important, the GRE Math Subject Test covers topics that are often not directly relevant to the specific mathematical requirements of most economics PhD programs. Many students and admissions committees now recognize that the test does not fully capture the advanced mathematical skills needed for economics PhD programs.
Why the GRE Math Subject Test May Not Be Useful
Calculus: Understanding differential and integral calculus is highly beneficial, especially in the context of econometrics and mathematical economics. However, the GRE Math Subject Test does not delve deeply into these areas, making it only a partial reflection of the deeper mathematical abilities required for advanced economics.
Algebra: Linear algebra is indeed necessary in advanced economics, particularly in econometrics and optimization. However, the GRE Math Subject Test's coverage of algebra is limited, often focusing more on basic linear algebra rather than the advanced concepts required for PhD-level work.
Other Topics: The other topics, including number theory and abstract algebra, are not typically considered essential for economics. These areas are more relevant for fields such as pure mathematics or theoretical physics.
What PhD Programs Really Want
PhD programs in economics seek candidates who have a solid foundation in rigorous, proof-based mathematics. This typically includes a strong understanding of real analysis, where students grapple with abstract concepts and complex proofs. The GRE Math Subject Test does not adequately measure these skills due to its multiple-choice format.
Specific Scenarios
Weaker Programs: For students applying to less selective programs, the GRE Math Subject Test can serve as a way to demonstrate their mathematical aptitude. These programs may be less concerned with advanced mathematical skills, especially if their undergraduate coursework does not include extensive mathematical content.
Quality PhD Programs: For highly competitive PhD programs, the GRE Math Subject Test may not significantly impact the admissions process. Departments might consider other factors, such as the applicant's research experience, letters of recommendation, and overall academic performance, to gauge their readiness for a PhD program.
Conclusion
While the GRE Math Subject Test can be useful for showing mathematical aptitude, its coverage of advanced mathematical skills is limited. Applicants should focus on developing a strong foundation in proof-based mathematics, particularly in areas such as real analysis and algebra. It's also advisable to check if the specific PhD program accepts this test and how it factors into their admissions process.
