The Distributional Impacts Of Transportation Networks In China, Lin Ma, Yang Tang
The Distributional Impacts Of Transportation Networks In China, Lin Ma, Yang Tang
Research Collection School Of Economics
We document that the quality of roads and railroads vary substantially over time and space in China, and neglecting these variations biases the distributional impacts of transportation networks. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model for multiple modes, transportation routes, and forward-looking migration decisions. Our findings demonstrate that disregarding quality differences leads to a median bias of approximately 31% in estimating real wage growth rates …

This paper evaluates the distributional impacts of transportation networks in China.We show that the quality of roads and railroads vary substantially over time and space, and ignoring these variations biases the estimates of travel time. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model that allows for multiple modes and routes of transportation and forward-looking migration decision.We find aggregate welfare gain and less spatial income inequality led …

This paper evaluates the impacts of migration flows and transportation infrastructure on the spatial transmission of COVID-19 in China. Prefectures with larger bilateral migration flows and shorter travel distances with Hubei, the epicenter of the outbreak, experienced a wider spread of COVID-19. In addition, richer prefectures with higher incomes were better able to contain the virus at the early stages of community transmission. Using a spatial general equilibrium model, we show that around 28% of the infections outside Hubei province can be explained by the rapid development in transportation infrastructure and the liberalization of migration restrictions in the recent decade.
Geography, Trade, And Internal Migration In China, Lin Ma, Yang Tang
Geography, Trade, And Internal Migration In China, Lin Ma, Yang Tang
Research Collection School Of Economics
This paper quantitatively studies the local welfare impacts of inter-city migration in China. We structurally estimate a trade model with endogenous migration decisions using data from 279 prefecture-level cities. The results suggest that inflows of migrant workers increase welfare in the destination cities between 2000 and 2005 despite their negative impacts on congestion and nominal wage. The positive local impacts of migration depend crucially on the endogenous firm entry. The positive impacts in the destination cities also spill over to the neighboring cities through inter-city trade, often leading to higher welfare gains in the nearby cities than the destination cities …
