Which structure is responsible for all non-home-country activities and is often set up when a firm initially expands abroad?

The International Division Structure is indeed the correct choice for this question. This organizational structure is often established when a company begins to expand its operations beyond its home country. The key characteristic of the International Division Structure is that it centralizes all non-home-country operations under a single division, which can streamline management and operations as the firm navigates the complexities of international markets.

When a firm first ventures into international business, it typically faces numerous challenges including cultural differences, regulatory environments, and logistical considerations. By creating an International Division, the company can focus its resources, expertise, and strategies specifically on managing its activities outside of its home country, facilitating more coordinated and effective operations.

Other structures, such as the Global Product Structure, Geographic Region Structure, and Global Functional Structure, have varying focuses. The Global Product Structure emphasizes product lines over geographic areas, while the Geographic Region Structure organizes operations based on geographic areas but may not necessarily centralize all non-home activities. The Global Functional Structure centers around specific functions, such as marketing or finance, rather than focusing on international operations as a whole. Thus, the International Division Structure most directly addresses the needs of a firm when it expands initially into international markets.
