  2. Possible answers: • Each country identifies itself by a geographical area over which it claims sovereignty. • Each country has its own government (political system) and its own of rules and regulations. The political systems of most nation states are different. • Activities or transactions leading to movements of people, factors of production (i.e., labor, capital and raw materials), manufactured goods and services across a county's borders are often controlled or restricted and in some cases are prohibited.

  3.

  19. Early Thinking about Trade • Mercantilism • Advocating exports and accumulation of gold and other precious metals • David Hume and the specie-flow mechanism • Accumulation of gold => domestic inflation => decline of exports and increase in imports • Adam Smith (1776) • Trade is beneficial for both trading partners (countries) if each specializes in the production of the good she is more efficient in.
