Foreign direct investment (FDI) involves a company from one country making a physical investment in building or expanding a business in another country. There are several potential benefits of FDI for host countries, including transferring technology, exploiting natural resources, and generating employment. However, the effects of FDI depend on the type (e.g. greenfield vs mergers and acquisitions) and can include both positive and negative externalities. Political risk also affects foreign investment and refers to complications from political decisions and instability in a country that impact business objectives and outcomes.
