The political economy of reforming agricultural support policies
Agricultural support policies cost more than US$800 billion per year in transfers to the farm sector worldwide. Support policies based on subsidies and trade barriers are highly distortive to markets and are also regressive as most support is provided to larger farmers. On balance, the incentives this support creates appear to increase greenhouse gas emissions that contribute to climate change. In addition, some subsidies undermine the production of more nutrient-dense commodities that are otherwise critical for the improvement of dietary outcomes.
