To explain why ending hunger has been so hard, Peter Timmer highlights four main themes: the complex role of markets, the importance of government policies, the historical process of structural transformation, and the need to identify the appropriate time horizon for analysis and interventions. These themes are not new, but integrating them into a coherent approach to ending hunger seems to be original
Trade is a key tool to bring food security to an estimated 800 million people around the world that remain chronically undernourished. Many countries need reliable access to international markets to supplement their inadequate domestic food supplies. Better policies to make agriculture in developing countries more productive and profitable, including via exports, would also help alleviate food insecurity and reduce poverty. Stronger international trade rules would help by constraining the beggar-thy-neighbor policies that distort trade, contribute to price volatility, and discourage investments in developing-country agriculture.
