Countries can improve their gross national income (GNI) through foreign investment and sending people out of the country to get jobs.
- Foreign investment brings in capital which can stimulate economic growth and increase income levels.
- Sending people out of the country to get jobs can lead to remittances, which are financial transfers sent back home that can significantly contribute to a country's GNI.
The other options, such as blocking international trade and increasing imports, are unlikely to have a positive effect on GNI. Blocking international trade can reduce overall economic activity, and increasing imports typically does not directly contribute to GNI.
