November 2017The Effect of Air Pollution on Migration: Evidence from China
with Shuai Chen, Paulina Oliva: w24036
This paper looks at the effects of air pollution on migration in China using changes in the average strength of thermal inversions over five-year periods as a source of exogenous variation for medium-run air pollution levels. Our findings suggest that air pollution is responsible for large changes in inflows and outflows of migration in China. More specifically, we find that independent changes in air pollution of the magnitude that occurred in China in the course of our study (between 1996 and 2010) are capable of reducing floating migration inflows by 50 percent and of reducing population through net outmigration by 5 percent in a given county. We find that these inflows are primarily driven by well educated people at the beginning of their professional careers, leading to substantial ch...
Temperature Effects on Productivity and Factor Reallocation: Evidence from a Half Million Chinese Manufacturing Plants
with Olivier Deschenes, Kyle C. Meng, Junjie Zhang: w23991
This paper uses detailed production data from a half million Chinese manufacturing plants over 1998-2007 to estimate the effects of temperature on firm-level total factor productivity (TFP), factor inputs, and output. We detect an inverted U-shaped relationship between temperature and TFP and show that it primarily drives the temperature-output effect. Both labor- and capital- intensive firms exhibit sensitivity to high temperatures. By mid 21st century, if no additional adaptation were to occur, we project that climate change will reduce Chinese manufacturing output annually by 12%, equivalent to a loss of $39.5 billion in 2007 dollars. This implies substantial local and global economic consequences as the Chinese manufacturing sector produces 32% of national GDP and supplies 12% of globa...
