Nations trade with each other when, on their own, they do not have the resources, or capacity to satisfy their own needs and wants. By developing and exploiting their domestic scarce resources, countries can produce a surplus, and trade this for the resources they need.
Division of labour
In its strictest sense, a division of labour means breaking down production into small, interconnected tasks, and then allocating these tasks to different workers based on their suitability to undertake the task efficiently. When applied internationally, a division of labour means that countries produce just a small range of goods or services, and may contribute only a small part to finished products sold in global markets. For example, a bar of chocolate is likely to contain many ingredients from numerous countries, with each country contributing, perhaps, just one ingredient to the final product.
Specialisation
Specialisation is the second fundamental principle associated with trade, and results from the division of labour. Given that each worker, or each producer, is given a specialist role, they are likely to become efficient contributors to the overall process of production, and to the finished product. Hence, specialisation can generate further benefits in terms of efficiency and productivity.

     Basic economic problems and their solutions.
     

Key words: Unemployment, income inequality, low quality of life.
The solution for unemployment is, of course, to create new jobs. The number of jobs that need to be created depends on the unemployment rate and the number of people entering the labor force in search of work. When unemployment creeps above 6% to 7% and stays there, it means the economy can't create enough new jobs.
