Final answer:
A global firm is a multinational corporation that operates across multiple countries, integrating various aspects of its operations to leverage international advantages. These firms significantly impact globalization and contribute to the economies where they have a presence. Option E is therefore the correct answers.
Step-by-step explanation:
A global firm is best described by option E: A firm that operates in more than one country and captures R&D, production, logistical, marketing, and financial advantages not available to purely domestic competitors. This aligns with the comprehensive definition of a multinational corporation (MNC), which is an entity with manufacturing or service operations in various countries. MNCs are significant players in the global economy, often influencing legal and economic policies in the countries where they operate due to their substantial assets and influence.
When discussing the broader context, such organizations play vital roles in globalization—a trend that reflects increased cross-national market interactions for buying and selling goods and services. Multinationals not only contribute to the GDP and business cycles of the countries in which they operate, but they also drive employment and control significant capital and production capacities without regard to national borders.
