Bachelor of Science Double Major in Mathematics & Economics

3 Years On Campus Bachelors Program

Polytechnic Institute of Paris

Program Overview

The Bachelor of Science Double Major in Mathematics & Economics at École Polytechnique is a unique three-year program that blends a rigorous mathematical approach to economics, helping you build skills in abstract modeling, data analysis, and logical thinking to tackle real-world problems. It's perfect for students like you who love numbers, enjoy quantitative challenges, and want to understand how economies work through science-backed methods—preparing you for top careers in finance, policy, or research.

Curriculum Structure
First Year
You'll kick off with a strong foundation in core sciences, including an Introduction to Economics class that teaches basic concepts and how to apply logic to economic questions, alongside Mathematics, Computer Science, and Physics. This year builds your quantitative skills and lets you explore options to confirm this double major is your fit, with opportunities to dip into labs and interact with researchers right away.

Second Year
Here, the program dives deeper into a math-oriented take on economics, with courses like Microeconomics (analyzing household and firm behavior, strategic interactions, and market equilibrium), Macroeconomics (exploring growth, business cycles, monetary policy, and fiscal tools), Econometrics (using stats to test theories against real data), and Finance (evaluating investments in uncertain settings). You'll also join Economics Workshops to apply these ideas to real-life scenarios, sharpening your ability to think critically and quantitatively.

Third Year
Advanced topics take center stage, including Game Theory, International Trade, Industrial Organization, Public Policy, Labor Economics, and Poverty and Development, plus broader courses in Law, History, Sociology, and Anthropology. You'll cap it off with a Bachelor Thesis as a hands-on research project, letting you dive into a topic you're passionate about and showcase your expertise.

Focus Areas
Core strengths include mathematical modeling of economic behavior, empirical data analysis via econometrics, strategic decision-making through game theory, and policy applications in trade, labor, and development—all grounded in abstract thinking and real-world testing.

Learning Outcomes
Graduates master constructing and interpreting economic models, applying statistical tools to data, reasoning logically under uncertainty, and conducting independent research—equipping you with versatile skills for complex problem-solving in economics and beyond.

Professional Alignment (Accreditation)
The program earns a fully accredited Bachelor of Science degree (180 ECTS), making you eligible for master's programs worldwide, with a scientific edge that aligns perfectly with grad studies in economics, finance, or data science.

Reputation (Employability Rankings)
École Polytechnique's Bachelor grads are highly sought after, with strong placement in top firms and programs—our alumni from this double major excel in competitive fields, backed by the school's elite status in global science education.

Experiential Learning (Research, Projects, Internships etc.)

At the Polytechnic Institute of Paris, our Bachelor of Science Double Major in Mathematics & Economics stands out because students dive into hands-on learning right from year one, building real-world skills through workshops, research projects, and direct access to cutting-edge facilities. You'll sharpen your logical thinking with mathematical models applied to economics, tackling everything from market behaviors to policy impacts via empirical data and experiments. In years two and three, this ramps up with Economics Workshops that explore practical applications, plus a capstone Bachelor Thesis as an independent research project—giving you invaluable experience in analysis and problem-solving that employers love.

This practical focus connects directly to our world-class resources designed for double major students:

- Laboratories: Enter École Polytechnique's research labs from your first year to interact with scientists, experiment with data, and apply economic models in real research environments.
- Economics Workshops: Hands-on sessions in year two to study real-life economic applications, bridging theory and practice.
- Bachelor Thesis Research Project: A third-year requirement where you conduct original research, using empirical data from field sources or controlled experiments.
- Minor in Computational Mathematics (optional for top performers): Adds practical tools for economic modeling, with access to math-focused computing resources.

Imagine putting all this to work—it's why our grads are ready to lead in finance, policy, and beyond.
