Globalization refers to the increasing integration and interdependence of world economies through increased trade and financial flows. It involves two components: the globalization of markets, where domestic markets become international markets, and the globalization of production, where components and goods are produced across multiple countries. Lowering of trade barriers since WWII and advances in technology have accelerated globalization trends dating back 10,000 years. Notable global institutions that have emerged to govern economic interactions include the WTO, IMF, World Bank, and UN.
