I came across a new database which provides in-depth information on the nature of trade agreements that have been entered between the period 1947 and 2010.
As the website says, “The Design of Trade Agreements Database (DESTA) aims to systematically collect data on various types of preferential trade agreements (PTAs). These may be customs unions, free trade agreements or partial free trade agreements (or what economists often call economic integration agreements). DESTA covers approximately 790 PTAs with information on a large set of design features, including sector coverage, depth of commitments, trade integration and compliance tools for the time period between 1947 and 2010. So far we have coded 587 agreements (as of June 2013).”
While it is extremely difficult (rather impossible) to get information on imports and exports under trade agreements publicly (I still can’t find any such information for India.. well does the Ministry of Commerce, Government of India, has it to begin with?), any information on trade agreements is helpful.
