Project Ideas for Doctor of Philosophy in Economics

Front-rank quantitative research driving policy and market innovation.

🏛 Introduction

Northwestern’s Economics PhD develops scholars who marry rigorous micro-theory with big-data empirics to solve real-world puzzles—from carbon pricing to fintech adoption. Doctoral students publish in *AER* and *QJE* while leveraging Chicago-Fed micro-data, satellite-imaging land-use panels, and machine-learning causal tools. Joint workshops with Kellogg and the Institute for Policy Research hone both academic and policy voice, preparing graduates for tenure-track posts, central-bank fellowships, and tech-economist leadership.
