Are the statements true, false, or uncertain arguments? An export tax always reduces the exporter's net revenues. It is highly evident which industries will produce more technological spillovers and which less. The bulk of child employment is in the tradeable sector of poor countries. The real cause of child labor is low GDP per capita. Trade restrictions save jobs that are more visible, but result in job losses elsewhere. When trade is diverted away from countries that employ children, the children allocate more time to education. When subsidies are not an option, import tariffs are a second-best policy to promote key industries. The main, perhaps only, concern of U.S. labor unions regarding their fellow workers in developing countries are the working conditions of those foreign workers.
