Globalization refers to the increasing integration of economies around the world through reductions in trade barriers and increases in flow of goods, services, and capital between countries. It leads to more specialization internationally and an increased material wealth. Foreign direct investment contributes directly to international business by allowing companies to invest across borders through mechanisms like mergers and acquisitions or building new facilities in other countries. This increases productivity in the host country and can transfer skills and technology. However, political stability, legal systems, economic conditions, and currency fluctuations in different countries can significantly impact foreign businesses operating there.
