|April 2019||The Impact of Global Warming on Rural-Urban Migrations: Evidence from Global Big Data|
with : w25728
This paper examines the impact of temperature changes on rural-urban migration using a 56km×56km grid cell level dataset covering the whole world at 10-year frequency during the period 1970-2000. We find that rising temperatures reduce rural-urban migration in poor countries and increase such migration in middle-income countries. These asymmetric migration responses are consistent with a simple model where rural-urban earnings differentials and liquidity constraints interact to determine rural-to-urban migration flows. We also confirm these temperature effects using country-level observations constructed by aggregating the grid cell level data. We project that expected warming in the next century will encourage further urbanization in middle-income countries such as Argentina, but it will ...
|July 2018||Explaining the Employment Effect of Exports: Value-Added Content Matters|
in Globalization and Welfare Impacts of International Trade, Shin-ichi Fukuda, Takeo Hoshi, and Fukunari Kimura, organizers
This paper estimates and decomposes the impact of export opportunities on countries’ employment by using a global input-output analysis, focusing on the U.S., China, and Japan. The greater they export, the greater employment in the exporting countries. However, we first document that the number of jobs created per exports varies substantially across destination countries. We find that exports from sectors with higher domestic value-added contents such as natural resource, textile, and service sectors lead to a greater employment effect. As a result, cross-country differences in sectoral compositions of exports explain a large part of the variations in the employment effects across destination countries. Time series changes in the employment effect of exports come from changes in (1) the la...
|November 2017||The ‘China Shock’, Exports and U.S. Employment: A Global Input-Output Analysis|
with : w24022
We quantify the impact on U.S. employment from imports and exports during 1995-2011, using the World Input-Output Database. We find that the growth in U.S. exports led to increased demand for 2 million jobs in manufacturing, 0.5 million in resource industries, and a remarkable 4.1 million jobs in services, totaling 6.6 million. One-third of those service sector jobs are due to the intermediate demand from merchandise (manufacturing and resource) exports, so the total labor demand gain due to merchandise exports was 3.7 million jobs. In comparison, U.S. merchandise imports from China led to reduced demand of 1.4 million jobs in manufacturing and 0.6 million in services (with small losses in resource industries), with total job losses of 2.0 million. It follows that the expansion in U.S. mer...
