Yero Samuel Ndiaye

Welcome! I am a PhD candidate in Economics at the University of Cologne and the Max Planck Institute for Behavioral Economics, affiliated with ECONtribute (Area: Market Design and Behavior) and the Center for Social and Economic Behavior (C-SEB). I hold an MSc in Statistics from the London School of Economics, where I received the Royal Statistical Society Prize for Best Graduate, and an MSc and BSc in Economics from the University of Cologne, all with Distinction.

I will be on the job market in 2026/27.

My research investigates how information and institutional design shape decisions in markets. I focus on health economics, auctions, and political economy, combining laboratory and field experiments, microeconomic theory, and modern causal inference methods.

Who Should Know What and Why? Curated Supply of Political Information

Job Market Paper — Working paper coming soon

Inaccurate political beliefs persist not only because people encounter falsehoods, but because truths that would correct them are selectively withheld. In a pre-registered experiment with 1,200 representative U.S. adults, senders decide whether to share verified immigration statistics with receivers who hold inaccurate beliefs. Senders provide accurate information at high rates (above 80%), but are 7 percentage points more likely to share facts aligned with their political position than facts that contradict it—even when receivers cannot take political action. This selectivity doubles to 13 percentage points when receivers make a consequential political decision, with the amplification operating primarily through withholding of unaligned information. The baseline alignment gap reflects an expressive preference for belief congruence; its doubling under political action reflects instrumental strategy. This curated truth—the selective provision of accurate information—distorts the information environment through a channel that existing fact-checking and anti-misinformation policies cannot reach. #information #experiment #political-economy
