Answer to Question 2
Political risk is defined as the risk of loss when investing in a given country caused by changes in a country's political structure or policies, such as tax laws, tariffs, expropriation of assets, or restriction in repatriation of profits. In general, political risk is lowest in countries that have a history of stability and consistency. Political risk tends to be highest in nations that do not have this sort of history. Three major types of political risk can be encountered: ownership risk, which exposes property and life; operating risk, which refers to interference with the ongoing operations of a firm; and transfer risk, which is mainly encountered when attempts are made to shift funds between countries.
