This book postulates the proposition that small economies exhibit a higher degree of outward orientation and structural adaptability, compared to their larger counterparts within the context of the European Union and two case studies (i.e. Catalonia and New Zealand).The number of nations has doubled in the last half of the century to around 200 independent economic units. Moreover, the break-up of the former Soviet bloc into a large number of small independent nations in Central and Eastern Europe, and the continued threat of separatist groups (i.e. Canada, Spain, and Sri Lanka) have sparked economists' interest to focus on the size of nations once again. This book offers a more comprehensive measurement of smallness than the conventional one for the analysis of the globalization strategies and flexibility of countries to overcome smallness.
