Research

My research sits at the intersection of microeconomic theory and transportation and urban economics: how public transit should be financed, market design, and discrete choice models.

    Financing Transit Through Economic Activity

    with Kevin Hasker and Eren İnci

    Develops an equilibrium model in which transit serving shopping trips is financed by a fare and a sales tax. Shifting revenue from the fare to the sales tax raises welfare; the welfare-maximizing fare is zero. The result is driven by an insurance effect (the fare is paid regardless of whether a purchase occurs, the tax only upon purchase) and reinforced by a participation effect under economies of scale.

  • M.A. thesis

    Optimal Financing of Public Transit

    Advisor: Eren İnci · Sabancı University, expected 2027

  • Ongoing project

    Time vs. Money Under Conscription: A Hybrid Choice Analysis of Turkey’s Paid Military Service

    Team of four, ECON 635 Discrete Choice Methods · Sabancı University, Fall 2025

    Proposes a hybrid choice (ICLV) specification of the choice between six-month standard service and a three-week paid exemption to estimate the value of time, with latent attitudes shifting time and cost sensitivities. Estimation in Biogeme (Python) is in progress.

Mathematics background

Before moving to economics I worked on low-dimensional topology and homological methods.
