Working Papers

The Local Multiplier Effects of Trade (Job Market Paper)

• Build a multi-sector, 31-province quantitative spatial model calibrated to China’s 2017 MRIO table.
• Study how trade shocks propagate through production networks and local labor markets.
• Show substantial local heterogeneity in multiplier effects, with model-implied multipliers ranging from 0.30 to 1.02.
• Estimate a real export-GDP multiplier of at least 1.721 using shift-share IV.

High-Speed Rail and Market Integration

• Construct a panel with 3.99 million city-pair-month observations from daily wholesale prices in 117 Chinese cities.
• Combine city-pair prices with AutoNavi intercity mobility indices.
• Use staggered HSR rollout and the Green Passage Policy for identification.
• Find that HSR connectivity reduces intercity price dispersion by about 2% on average and up to 5% in short-haul markets.

Other Applied Work
