A foreign direct investment (FDI) refers to purchase of an asset in another country, such that it gives direct control to the purchaser over the asset (e.g. purchase of land and building). In other words, it is an investment in the form of a controlling ownership in a business, in real estate or in productive assets such as factories in one country by an entity based in another country. It is thus distinguished from a foreign portfolio investment or foreign indirect investment by a notion of direct control.
The origin of the investment does not impact the definition, as an FDI: the investment may be made either "inorganically" by buying a company in the target country or "organically" by expanding the operations of an existing business in that country.
Definitions
Broadly, foreign direct investment includes mergers and acquisitions, building new facilities, reinvesting profits earned from overseas operations, and intra company loans. In a narrow sense, foreign direct investment refers just to building new facility, and a lasting management interest (10 percent or more of voting stock) in an enterprise operating in an economy other than that of the investor. FDI is the sum of equity capital, long-term capital, and short-term capital as shown in the balance of payments. FDI usually involves participation in management, joint-venture, transfer of technology and expertise. Stock of FDI is the net (i.e., outward FDI minus inward FDI) cumulative FDI for any given period. Direct investment excludes investment through purchase of shares (if that purchase results in an investor controlling less than 10% of the shares of the company).
FDI, a subset of international factor movements, is characterized by controlling ownership of a business enterprise in one country by an entity based in another country. Foreign direct investment is distinguished from foreign portfolio investment, a passive investment in the securities of another country such as public stocks and bonds, by the element of "control". According to the Financial Times, "Standard definitions of control use the internationally agreed 10 percent threshold of voting shares, but this is a grey area as often a smaller block of shares will give control in widely held companies. Moreover, control of technology, management, even crucial inputs can confer de facto control."
Theoretical background
Before Stephen Hymer's landmark work on FDI in 1960, no theory existed that dealt specifically with FDI. However, there are theories that dealt generally with foreign investments. Both Eli Heckscher (1919) and Bertil Ohlin (1933) developed the theory of foreign investments by using neoclassical economics and macroeconomic theory. Based on this principle, the differences in the costs of production of goods between two countries cause specialisation of jobs and trade between countries. Reasons for differences in costs of production can be explained by factor proportions theory. For example, countries with a greater proportion of labour will engage in labor-intensive industries while countries that have a greater proportion of capital will engage in capital-intensive industries. However, such a theory makes the assumption that there is perfect competition, there is no movement of labour across country borders, and the multinational companies assumes risk neutral preferences. In 1967, Weintraub tested this hypothesis by collecting United States data on rate of return and flow of capital. However, the data failed to support this hypothesis. Data from surveys on the motivation of FDI also failed to support this hypothesis.
