Applied Economist

I work with large market datasets to understand how prices, promotions, market structure, and mobility relate to demand and market outcomes, then translate that evidence into forecasts, scenarios, and decision-support tools. My work spans 6.6M retail scanner records, 8.68M historical market records, mobility traces, input-output tables, customs micro-data, and geospatial rasters.

Retail pricing decisions

How should price and promotion changes be tested before rollout?

I estimate demand response, simulate price and promotion scenarios, and optimize profit under cost, inventory, and margin constraints. Core asset: Pricing and Promotion Decision Engine.

Commodity prices and market integration

How do mobility and connectivity shocks change spatial price dispersion?

I use high-frequency wholesale prices and smartphone-based mobility data to study how passenger connectivity, rather than freight costs, shapes spatial price dispersion across Chinese cities. Core asset: HSR and Market Integration paper.

Trade-cost shocks and local multipliers

Why do similar external shocks produce different regional outcomes?

I build quantitative spatial models to measure how trade-cost shocks propagate through domestic production networks, local absorption, and non-tradable demand. Core asset: Trade shock paper.

Research and Tools

Selected work

Full research list

Decision Tool - 2025-Present

Pricing and Promotion Decision Engine

Built on 6.6M rows of Dominick's scanner data: log-log fixed-effects demand estimation, price and promotion counterfactuals, constrained profit optimization under cost and margin inputs, and A/B power calculations, deployed as a live Streamlit app.

Market Intelligence - 2026-Present

Vegetable Price Intelligence

Built an auditable historical price system from 8.68M market records: rolling forecasts, a validation-frozen price-risk signal, and explicit fallbacks or no-go decisions when out-of-sample evidence did not support a stronger product claim.

Working Paper - 2022-2025

High-Speed Rail and Market Integration

Constructed a panel with 3.99 million city-pair-month observations from daily wholesale prices and mobility indices. Estimates indicate HSR connectivity lowers intercity price dispersion by about 2% on average and up to 5% in short-haul markets.

Working Paper - 2024-Present

The Local Multiplier Effects of Trade

Built a multi-sector quantitative spatial model for 31 Chinese provinces calibrated to MRIO, ICIO, and Customs micro-data. Identifies the own-trade share as the structural organizing statistic for multiplier heterogeneity, with inland inward-oriented economies amplifying external shocks through non-tradable service demand.
