UFC Fight Outcome Prediction Model

Machine Learning · Sports Analytics

A two-stage ML model to predict UFC fight outcomes. First classifies fighters by style, then predicts matchup results based on how those styles interact. Tracks model performance and hypothetical betting returns on a live dashboard.

Tale of the Tape: UFC Daily Challenge

Interactive Game · Sports Analytics

A daily UFC fighter guessing game where you identify a mystery fighter using stat comparisons. The other UFC daily games are pretty bad, so I built my own. New fighter every day.

The Real Price of Clean Air: EPA Ozone Regulation

Regulatory Economics · Causal Inference · Policy

Leverages the EPA's 0.071 ppm ozone threshold in a regression discontinuity design to quantify the revenue impact on U.S. manufacturing firms, finding a $277M annual reduction absent from the EPA's own analysis.

NYC Congestion Pricing: Mobility and Commercial Effects

Urban Economics · Causal Inference · Policy Research

Applied a difference-in-discontinuities design using C2Smart traffic camera data and MTA ridership records to estimate the causal effect of NYC's congestion pricing zone on vehicle traffic, pedestrian activity, subway ridership, and commercial outcomes at the 60th Street boundary.

Agentic LLMs for Economic and Game Theory Analysis

Applied AI · Behavioral Economics · Game Theory

Using Expected Parrot's EDSL framework (John Horton, MIT Sloan) to run agentic LLMs as simulated economic agents. Testing historical counterfactual prediction accuracy, causal impact analysis, and game-theoretic behavioral modeling. Explores whether Homo silicus replicates and extends findings from classic economics experiments.

About

Zach Winship

Zach Winship

Quantitative Economist and Data Analyst

I recently graduated from Bentley University with a BS in Quantitative Economics and a double minor in Mathematics and Data Technologies. I'm now pursuing the MS in Quantitative Economics at New York University, with expected graduation in May 2027.

My work sits at the intersection of data and policy. I'm drawn to questions where careful empirical methods can cut through noise and say something concrete about how the world works. I've built tools for sports prediction, transportation research, and political economy, always trying to combine rigor with work that's actually interesting to look at.

Outside of coursework I spend a lot of time on personal projects. I'm especially interested in transportation economics, spatial analytics, optimization problems, and the emerging field of Homo silicus — using large language models as simulated economic agents to replicate and extend classic experiments in economics and game theory. Feel free to look around. I had a lot of fun building these.

Infrastructure Maintenance: Evidence from India
Bentley University  ·  2026

Presented Chaurey and Le's paper on the RSVY program, India's 2003 to 2007 infrastructure maintenance initiative targeting 147 "backward districts." Using a regression discontinuity design around the backwardness index threshold, the paper finds that maintenance spending (not new construction) drove a 14 to 16% increase in village-level non-farm employment, entirely through informal microenterprises.
