Globalization is a phenomenon based on the continuous increase in the interconnection between the different nations of the world at the economic, political, social and technological levels. A key issue is interdependence linking different countries or regions.
A more connected world has a great impact on production, international trade, foreign investment, economic growth and labour markets: trade on goods and services, financial flows, migratory processes have been extremely increased in last five decades with a profoundly influence on international relationships.
As a consequence, on one hand, national issues are fading and it is difficult separate domestic from external economic activities. On the other hand, as a reaction, nationalist ideas have been raising over the time.
Globalization is, therefore, a complex idea that involves economy, politics, social issues, technology, and is driven by the convergence of cultural and economic systems but, in addition, another outcome is world inequality.
