I turn price, cost, demand, and market-integration data into empirical models, deployed tools, and clear decisions. My work spans 6.6M retail scanner records, 3.99M commodity-price observations, mobility traces, input-output tables, customs micro-data, and geospatial rasters, using causal inference, demand estimation, structural modeling, machine learning, and counterfactual simulation.
Retail pricing decisions
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
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
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
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.
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.
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.
