Globalization
One index of globalization is the "KOF Index of Globalization", which measures three important dimensions of globalization: economic, social, and political. Another is the A.T. Kearney / Foreign Policy Magazine Globalization Index.
Measurements of economic globalization typically focus on variables such as trade, Foreign Direct Investment (FDI), Gross Domestic Product (GDP), portfolio investment, and income. However, newer indices attempt to measure globalization in more general terms, including variables related to political, social, cultural, and even environmental aspects of globalization.
History of globalization
Between the globalization in the 19 th and in the 20th there are significant differences. There are two main points on which the differences can be seen. One point is the global trade in this centuries as well as the capital, investment and the economy.The global trade in the 20th century shows a higher share of trade in merchant production, a growth of the trade in services and the rise of production and trade by multinational firms.
The production of merchant goods in the 20th century largely decreased from the levels seen in the 19th century. However, the amount of merchant goods that were produced for the merchandise trade grew. 
The trade in services also grew more important in the 20th compared to the 19th century. 
The last point that distinguishes the global trade in the 19th century compared to the global trade in the 20th century, is the extent of multinational cooperation. In the 20th century you can see a "quantum leap" in multinational cooperation compared to the 19th century. Before the 20th century began, there were just Portfolio investment, but no trade-related or production-relation Direct investment.
