Migration And Resource Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang Mar 2024

Migration And Resource Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang

Research Collection School Of Economics

We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equilibrium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with firm productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture misallocation increases aggregate welfare, discourages migration toward large prefectures, and reduces spatial inequality. Moreover, internal migration alleviates micro-frictions’ impacts on aggregate welfare and worsens their effects on spatial inequality.


The Distributional Impacts Of Transportation Networks In China, Lin Ma, Yang Tang Mar 2024

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 …

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Tang Yang

Research Collection School Of Economics

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 …

Migration And Spatial Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang

Research Collection School Of Economics

We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equi-librium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture mis-allocation increases the aggregate welfare, discourages migration towards large cities, and narrows the spatial inequality. Moreover, internal migration alleviates the impacts of micro-frictions on aggregate welfare and worsens their impacts on spatial inequality.


Geography, Trade, And Internal Migration In China, Lin Ma, Yang Tang Jan 2020

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 …
