The relative political and economic stability of the United States has been an important factor in attracting foreign buyers. Political and economic instability can increase greatly the risk of what is already a riskier situation than purely domestic investments or acquisitions. Acquiring firms must consider the frequency with which the government changes, how orderly the transfer of power is, and how much government policies differ from one administration to the next, including the degree of difference between the dominant political parties. They Must assess the likelihood of government intervention on the upside and the downside (for example, subsidies, tax breaks, loan guarantees, and so forth, on the one hand, all the way to outright expropriation on the other hand).

Desirable economic factors include low, or at least predictable, inflation. Labor relations are another important consideration in economic stability. Western European labor unions appear to have a greater voice in the management of companies than do American unions.
