Globalization is characterized by increased flows of trade, capital, technology, information and people across borders. While not a new process, globalization accelerated after World War II due to technological advances. Supporters argue it raises living standards through comparative advantage and improves environmental/labor standards over time. Critics argue it harms some people and serves corporate interests by enabling a "race to the bottom" in regulations. Studies have shown mixed effects of globalization on economic growth, inequality, and poverty reduction between and within nations.
