International business is the study of business transactions that cross national boundaries.
Ancillary topics such as economic growth and development and ethics in international business are also generally covered. Transactions of both private and public entities are studied with a special focus on the operations of multinational corporations. International business involves all functional business areas and explores how these functions are impacted by expanding beyond the national arena. Particular emphasis is placed on the challenges presented by different sociocultural, political, and economic environments. International business studies are interdisciplinary in nature and are frequently combined with functional business studies or geographical area studies.
