Dr. Bilgin gravitated toward Matching Theory for its "human touch." Unlike macro indicators such as interest rates or stock prices, the field tackles how scarce resources meet real needs when money can't decide. The 2012 Nobel Prize marked a turning point, legitimizing Matching Theory & Market Design (and therefore Behavioral Economics) as forces reshaping mainstream economics.
From theory to real-world solutions
Today, the toolkit serves an array of pressing problems: assigning students to schools, pairing organ donors with recipients, rationing vaccines or ventilators in pandemics, placing refugees, and settling displaced populations due to climate issues. Centralized mechanisms, she argues, deliver fairer, faster outcomes. She half-jokes that "everything should be centralized," citing the chaotic academic job market as proof.
Everything should be centralized — the academic job market proves it.
An evolving, interdisciplinary toolkit
The field is also growing more interdisciplinary, weaving in behavioral insights, data-driven simulations, and laboratory experiments in a continual loop of modeling, testing, and refinement. This integrated approach strengthens the rigor and applicability of market design solutions across diverse domains.
Advice for students navigating economics
Dr. Bilgin reassures economics students that feeling adrift in the third or fourth year is common; the discipline is simply vast. Her coping strategy is keeping as many doors open as possible, sampling different paths, and not hesitating to close off options that clearly aren't a fit. Conserving effort, emotion, and time is itself an economic choice.
For those interested in Matching Theory, a highly theoretical branch of microeconomics and game theory, she urges a solid grounding in theory and suggests the following resources:
Introductory level: Alvin Roth's Who Gets What and Why for an overview.
Exploring people and applications: Oxford's "What Economists Do" video and podcast series, plus Alex Teytelboym's podcasts on refugee placement.
Core texts: A standard game-theory textbook, Roth & Sotomayor's Two-Sided Matching, and the new applications-oriented volume by Tayfun Sönmez and Utku Ünver.
Her message on theory is that theory paired with curiosity can turn an uncertain start into a rewarding, human-focused career. As the TED University Economics Research Union, we thank Dr. Bilgin for this valuable conversation.
