Talk Title: Climate Change, The Food Problem, and the Challenge of Adaptation through Sectoral Reallocation

Abstract: This paper combines local temperature treatment effects with a quantitative macroeconomic model to assess the potential for global reallocation between agricultural and non-agricultural production to reduce the costs of climate change. First, I use firm-level panel data from a wide range of countries to show that extreme heat reduces productivity less in manufacturing and services than in agriculture, implying that hot countries could achieve large potential gains by adapting to climate change through increasing imports of food and shifting labor toward manufacturing. To investigate the likelihood that such gains will be realized, I embed the empirically estimated productivity effects in a model of sectoral specialization and trade covering 158 countries. Simulations suggest that climate change does little to alter the geography of agricultural production, however, as high trade barriers in developing countries temper the influence of shifting comparative advantage. Instead, climate change accentuates the existing pattern, known as “the food problem,” in which poor countries specialize heavily in relatively low productivity agricultural production to meet subsistence consumer needs. The productivity effects of climate change reduce welfare by 6-10% for the poorest quartile of the world with existing trade barriers, but by 70% less in an alternative policy counterfactual that moves low-income countries to OECD levels of trade openness.
