Final answer:
The internalization theory recommends FDI over licensing in a stable regulatory environment.
Step-by-step explanation:
The internalization theory recommends FDI (Foreign Direct Investment) over licensing in a situation where there is a stable regulatory environment. Licensing involves granting permission to a foreign company to use intellectual property, while FDI entails establishing a physical presence in a foreign market. In a stable regulatory environment, FDI provides more control and flexibility for a company compared to licensing, ensuring they can adapt to any changes in regulations.
