Final answer:
In a polycentric staffing model, host country nationals are typically hired for higher-level positions in foreign operations, as they are familiar with the local environment and business practices.
Step-by-step explanation:
When using a polycentric staffing model, you would primarily use host country nationals to staff higher-level foreign positions. A polycentric staffing approach means that a multinational company is more likely to employ management that is from the host country where the subsidiary or foreign operation is located. This model is based on the understanding that locals have a better understanding of the local business environment, culture, language, and business practices, which can be advantageous in managing operations effectively in that country. By contrast, parent country nationals come from the company's home country, third-country nationals are hired from a country other than the host or home country, and regional specialists could be employed from any location with specific regional expertise.
