In cases where surpluses were generated, such as in the EU and United States, export subsidies were granted, which depressed international prices. As a result, these price support programmes with their accompanying stock creation started out as domestic measures, but eventually spilled over to international markets through the creation of trade barriers and their impact on world prices. The effects, however, can be similar to those of price support programmes as both programmes share the same objectives of stabilising prices and influencing the levels of prices.
